                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2019), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

Commandant, meets the standards in IMO Resolution A.739(18).
    Independent laboratory means an organization which meets the 
standards for acceptance in Sec.  159.010-3 of this part, and which is 
accepted by the Coast Guard for performing certain tests and 
inspections. In addition to commercial testing laboratories, the 
Commandant may also accept classification societies and agencies of 
governments that are involved in the inspection and testing of marine 
safety equipment that meet the requirements of Sec.  159.010-3.
    Marine Equipment Directive (MarED) means the European Community 
Council Directive 96/98/EC of December 20, 1996 on marine equipment, as 
amended.
    Memorandum of Understanding (MOU) is an agreement between the Coast 
Guard and a laboratory that specifies the approval functions a 
recognized independent laboratory performs for the Coast Guard and the 
recognized independent laboratory's working arrangements with the Coast 
Guard.
    Mutual Recognition Agreement (MRA) means an agreement between the 
United States and other Maritime Administrations or organized 
associations, such as the European Community and the European Free Trade

    (1) Manufacturer. Each manufacturer must--
    (i) Perform all tests and examinations necessary to show compliance 
with this subpart and subpart under which the life preserver is approved 
on each lot before any inspector's tests and inspection of the lot;
    (ii) Follow established procedures for maintaining quality control 
of the materials used, manufacturing operations, and the finished 
product; and
    (iii) Allow an inspector to take samples of completed units or of 
component materials for tests required by this subpart and for tests 
relating to the safety of the design.
    (2) Laboratory. An inspector from the accepted laboratory shall 
oversee production in accordance with the laboratory's procedures for 
production inspections and tests accepted by the Commandant. During 
production oversight, the inspector shall not perform or supervise any 
production test or inspection unless--
    (i) The manufacturer has a valid approval certificate; and
    (ii) The inspector has first observed the manufacturer's production 
methods and any revisions to those methods.
    (3) At least quarterly, the inspector shall check the manufacturer's 
compliance with the company's quality control procedures, examine the 
manufacturer's required records, and observe the manufacturer perform 
each of the required production tests.
    (c) Test facilities. The manufacturer shall provide a suitable place 
and apparatus for conducting the tests and inspections necessary to 
determine compliance of life preservers with this subpart. The 
manufacturer shall provide means to secure any test that is not 
continuously observed, such as the 48 hour buoyancy test. The 
manufacturer must have the calibration of all test equipment checked in 
accordance with the test equipment manufacturer's recommendation and 
interval but not less than at least once every year.
    (d) Lots. A lot may not consist of more than 1000 life preservers. A 
lot number must be assigned to each group of life preservers produced. 
Lots must be numbered serially. A new lot must be started whenever any 
change in materials or a revision to a production method is made, and 
whenever any substantial discontinuity in the production process occurs.

    (2) For a lot next succeeding one from which any sample life 
preserver failed the buoyancy test, the sample shall consist of not less 
than ten specimen life preservers to be tested for buoyancy in 
accordance with paragraph (f) of this section.
    (f) Buoyancy test. The buoyancy of the life preservers must be 
determined by measuring the upward force exerted by the individual 
submerged unit. The buoyancy measurement must be made at the end of the 
24 or 48 hours of submersion, as specified in the applicable approval 
subpart, during which period the pad inserts must not be disturbed.
    (g) Buoyancy required. The buoyancy must meet the requirements of 
the applicable approval subpart.
    (h) Lot inspection. On each lot, the laboratory inspector shall 
perform a final lot inspection to be satisfied that the life preservers 
meet this subpart. Each lot must demonstrate--
    (1) First quality workmanship;
    (2) That the general arrangement and attachment of all components, 
such as body straps, closures, tie tapes, and drawstrings, are as 
specified in the approved plans and specifications;
    (3) Compliance with the marking requirements in the applicable 
approval subpart; and
    (4) The information pamphlet specified in 33 CFR part 181 subpart G, 
if required, is securely attached to the device, with the PFD selection 
information visible and accessible prior to purchase.
    (i) Lot acceptance. When the independent laboratory has determined 
that the life preservers in the lot are of a type officially approved in 
the name of the company, and that such life preservers meet the 
requirements of this subpart, they shall be plainly marked in waterproof 
ink with the independent laboratory's name or identifying mark.
    (j) Lot rejection. Each nonconforming unit must be rejected. If 
three or more nonconforming units are rejected for the same kind of 
defect, lot inspection must be discontinued and the lot rejected. The 
inspector must discontinue lot inspection and reject the lot if 
examination of individual units or the records for the lot shows

Sec.  160.010-6  Capacity of buoyant apparatus.

    (a) The number of persons for which a buoyant apparatus is approved 
must be the lowest number determined by the following methods:
    (1) Final buoyancy of the buoyant apparatus in Newtons after the 
watertight integrity test as described in Sec.  160.010-7 (e) and (f), 
divided by 145 (divided by 32 if buoyancy is measured in pounds). The 
divisor must be changed to 180 (40 if buoyancy is measured in pounds) if 
the apparatus is designed so that persons supported are only partially 
immersed or where facilities are provided for climbing on top of the 
apparatus.
    (2) Number of 300 mm (1 ft.) increments in the outside perimeter of 
the buoyant apparatus. The inside edge of peripheral-body type buoyant 
apparatus is not considered in determining the capacity.
    (b) [Reserved]



Sec.  160.010-7  Methods of sampling, inspections and tests.

    (a) General. Production tests must be conducted under the procedures 
in subpart 159.007 of this chapter. An inspector from the independent 
laboratory must inspect the place of manufacture, observe the various 
operations involved in the construction process and determine that 
buoyant apparatus are made in accordance with this subpart and of 
materials and parts conforming strictly with the plans and 
specifications submitted by the manufacturer and approved by the 
Commandant (CG-ENG-4).
    (b) Sampling of production lots. A production lot must consist of 
not more than 300 buoyant apparatus of the same design and capacity 
manufactured by one factory. Samples for production tests must be 
selected at random from each lot. The required sample size for various 
lot sizes is given in Table 160.010-7(b).

------------------------------------------------------------------------

    (c) Testing of sample buoyant apparatus from production lots. Each 
sample buoyant apparatus selected for test from a production lot must be 
subjected to the tests described in paragraphs (d) through (g) of this 
section. The stability test in paragraph (h) must be performed whenever 
a question of stability arises.
    (d) Strength tests. The buoyant apparatus tested for approval must 
be subjected to the drop test. Buoyant apparatus tested for production 
lot inspections must also be subjected to the drop test except that in 
the case of peripheral body type apparatus, the beam loading test may be 
substituted.
    (1) Drop test. Drop the complete sample buoyant apparatus into still 
water from a height of 18 m (60 ft.) twice, once flat and once endwise. 
There must be no damage that would render the apparatus unserviceable.
    (2) Beam loading test. The buoyant apparatus must be stood on edge 
on one of its longer sides. A wood block 600 mm (24 in.) long and wide 
enough to cover the body of the apparatus must be centered on the top 
edge of the apparatus. A loading beam must be set at right angles to the 
float at a height so that the beam is in a horizontal position with its 
center on the center of the wood block. The loading beam must be hinged 
at one end and a load applied at the other end at a uniform rate of 225 
kg (500 lb.) per minute until the load at the end of the beam as shown 
on Table 160.010-7(d)(2) is reached. The beam is then held stationary 
for 10 minutes. The device used to apply the load must be a chain fall, 
hydraulic cylinder or other device that allows the device to unload as 
the

[[Page 39]]

strain on the buoyant apparatus relieves. At the end of the 10 minute 
period, the drop in the load on the device must not exceed the maximum 
permissible drop shown in Table 160.010-7(d)(2). If the buoyant 
apparatus is not one of the sizes listed in the table, the loads must be 
determined by linear interpolation.

    Note: Because of the lever ratio of the beam loading apparatus 
described here, the actual loads applied to the apparatus are twice the 
loads shown in the Table.

------------------------------------------------------------------------

    (e) Buoyancy test. Known weights are loaded on the sample buoyant 
apparatus until it is awash. The buoyancy is the downward force exerted 
by the weights loaded on the apparatus. A raised platform of known 
weight having two runners on edge spaced so as to bear on the apparatus 
may be used to support the weights out of water to avoid the necessity 
for making allowances for the displacement of submerged weights. This 
test is not a required production test if the manufacturer--
    (1) Uses the same plastic buoyancy foam used in previous production 
lots,
    (2) Determines that the density of each batch of foam used is within 
a range specified on the approved plans, and
    (3) Closely controls the amount of foam used in each apparatus.
    (f) Watertight integrity test. The buoyant apparatus is submerged 
for 24 hours at a depth of 3 m (10 ft.) or equivalent water pressure. 
The final buoyancy of the buoyant apparatus is determined in accordance 
with paragraph (e) of this section. The final buoyancy must be at least 
145 N (32 lb.) per person capacity of the buoyant apparatus or 180 N (40 
lb.) per person capacity if the apparatus is designed so that persons 
supported are only partially immersed or if facilities are provided for 
climbing on top of the apparatus. The loss of buoyancy must not exceed 5 
percent of the initial buoyancy. This test is not a required production 
test if the manufacturer uses the plastic buoyancy foam controls 
permitted as an alternative to the buoyancy test in paragraph (e) of 
this section.
    (g) Painter attachment strength test. The apparatus must be 
positioned with its painter attachment fitting at the lowest point of 
the apparatus, directly below the center of buoyancy. The apparatus must 
be suspended in this position from the highest side. A load equal to 
twice the buoyancy of the apparatus must be suspended from the painter 
attachment fitting for 10 minutes. The fitting must remain firmly 
attached to the buoyant apparatus and the apparatus must not sustain any 
visible damage.
    (h) Stability test. With the sample buoyant apparatus floating in 
water, a weight of 22.5 kg of iron per meter of length (15 lb. per foot) 
must be suspended in the water from the life lines along one of the 
longer edges. The same test must be performed along one of the shorter 
edges. The minimum weight along any one edge must be 27 kg (60 lb.). The 
buoyant apparatus must neither capsize nor become partially awash under 
either of these tests.
    (i) Weight test. One buoyant apparatus of the lot submitted for 
approval must be weighed. The weight of the complete buoyant apparatus 
must be within the limit required in Sec.  160.010-3(d).
    (j) Lot acceptance or rejection. Inability of a sample buoyant 
apparatus to pass any one or more of the tests required in this section 
causes rejection of the lot. Each buoyant apparatus in a rejected lot 
must be reworked by the manufacturer to correct the defects found before 
the lot is resubmitted for inspection and testing.

    (2) The top and bottom of each spacer ear must be attached to a 
suspension member.
    (3) The top point of attachment must be at least 100 mm (4 in.) 
above the top surfaces of the rungs attached to the spacer ear.

[[Page 43]]

    (4) Each spacer ear made of sheet metal must have features such as 
formed ribs, rolled flange edges, and stress relief holes at the ends of 
cuts, to prevent the ear from bending or tearing.
    (h) Fasteners. Each fastening device must have a means to prevent 
the device from loosening.
    (i) Workmanship. A ladder must not have splinters, burrs, sharp 
edges, corners, projections, or other defects that could injure a person 
using the ladder.

    (b) [Reserved]



Sec.  160.017-21  Approval tests.

    (a) General. Each approval test must be conducted on a ladder of the 
longest length for which approval has been requested. If a ladder fails 
one of the tests in this section, the cause of the failure must be 
identified and any needed changes made. After a test failure and any 
design change, the failed test, and any other previously completed tests 
affected by the design change, must be rerun.
    (b) Visual examination. Before starting the tests described in this 
section, an assembled chain ladder is examined for evidence of 
noncompliance with the requirements in Sec. Sec.  160.017.11, 160.017-
13, and 160.017-15.
    (c) The following approval tests must be conducted:
    (1) Strength test 1. An assembled ladder is supported so that a 
static load, if placed on any of its steps, would exert a force both on 
the step and each suspension member. A static load of 315 kg (700 lb.) 
is then placed on one step for at least one minute. The load must be 
uniformly distributed over a contact surface that is approximately 100 
mm (4 in.) wide. The center of the contact surface must be at the center 
of the step. This test is performed on six different steps. No step may 
break, crack, or incur any deformation that remains after the static 
load is removed. No attachment between any step and a suspension member 
may loosen or break during this test.
    (2) Strength test 2. A ladder is suspended vertically to its full 
length from its top lashing rings. A static load of 900 kg (2000 lbs.) 
is then applied to the bottom lashing rings so that it is distributed 
equally between the suspension members. The suspension members, lashing 
rings, and spacer ears must not break, incur any elongation or 
deformation that remains after the test load is removed, or be damaged 
in any other way during this test.
    (3) Strength test 3. A rolled-up ladder is attached by its top 
lashing rings to anchoring fixtures in a location away from any wall or 
structure that would prevent it from falling freely, and where it can 
hang to its full length vertically. The ladder when dropped must unroll 
freely. When unrolling the ladder, its steps and attachments must not 
become cracked, broken, or loosened. Other similar damage making the 
ladder unsafe to use must likewise not occur.



Sec.  160.017-25  Marking.

    (a) Each chain ladder step manufactured under Coast Guard approval 
must be branded or otherwise permanently and legibly marked on the 
bottom with--
    (1) The name of the manufacturer;
    (2) The manufacturer's brand or model designation;
    (3) The lot number and date of manufacture; and
    (4) The Coast Guard approval number.
    (b) [Reserved]



Sec.  160.017-27  Production tests and examination.

    (a) General. Each ladder manufactured under Coast Guard approval 
must be tested in accordance with this section and subpart 159.007 of 
this chapter. Steps that fail testing may not be marked with the Coast 
Guard approval number and each assembled ladder that fails testing may 
not be sold as Coast Guard approved.

[[Page 44]]

    (b) Test 1: Steps. Steps must be separated into lots of 100 steps 
or less. One step from each lot must be selected at random and tested as 
described in Sec.  106.017-21(c)(1), except that the step may be 
supported at the points where it would be attached to suspension members 
in an assembled ladder. If the step fails the test, ten more steps must 
be selected at random from the lot and tested. If one or more of the ten 
steps fails the test, each step in the lot must be tested.
    (c) Test 2: Ladders. Assembled ladders must be separated into lots 
of 20 ladders or less One ladder must be selected at random from the 
ladders in the lot. The ladder selected must be at least 3 m (10 ft.) 
long or, if each ladder in the lot is less than 3 m long, a ladder of 
the longest length in the lot must be selected. The ladder must be 
tested as prescribed in Sec.  160.017-21(c)(2), except that only a 3 m 
section of the ladder need be subjected to the static load. If the 
ladder fails the test each other ladder in the lot must be tested.
    (d) Independent laboratory. Each production test must be conducted 
or supervised by an independent laboratory. However, if a test is 
performed more than 4 different times per year, laboratory participation 
is required only 4 times per year. If the laboratory does not 
participate in all tests, the times of laboratory participation must be 
as selected by the laboratory. The times selected must provide for 
effective monitoring throughout the production schedule.
    (e) Visual examination. The visual examination described in Sec.  
160.017-21(b) must be conducted as a part of each production test.

Sec.  160.021-2  Type.

    (a) Hand red flare distress signals specified by this subpart shall 
be of one type which shall consist essentially of a wooden handle to 
which is attached a tubular casing having a sealing plug at the handle 
end, the casing being filled with a flare composition and having a 
button of ignition material at the top, with a removable cap having a 
friction striking material on its top which may be exposed for use by 
pulling a tear strip. The flare is ignited by scraping the friction 
striker on top of the cap against the igniter button on top of the 
flare. The general arrangement of the flare is shown by Figure No. 
160.021-2(a). Alternate arrangements which conform to all the 
performance requirements of this specification (and other arrangements 
which conform with all performance requirements except candlepower and 
burning time, but provide not less than 3,000 candela-minutes with a 
minimum of \1/3\ minute burning time) will be given special 
consideration.

Sec.  160.021-3  Materials, workmanship, construction and 
performance requirements.

    (a) Materials. The materials shall conform strictly to the 
specifications and drawings submitted by the manufacturer and approved 
by the Commandant. The color of the tube shall be red. Flare 
compositions containing sulphur shall not contain more than 2.6 percent 
of potassium chlorate or an equivalent amount of any other chlorate. 
Flare compositions containing chlorates in any quantity shall not 
contain any ammonium salts.
    (b) Workmanship. Hand red flare distress signals shall be of first 
class workmanship and shall be free from imperfections of manufacture 
affecting their appearance or that may affect their serviceability. 
Moistureproof coatings shall be applied uniformly and shall be free from 
pinholes or other visible defects which would impair their usefulness.
    (c) Construction. The casing shall be fitted and secured to the 
handle with not less than a 25 mm (1 in.) overlap and shall be attached 
to the handle in such a manner that failure of the joint will not occur 
during tests, ignition, or operation. The plug shall be securely affixed 
in the casing to separate the flare composition from the wooden handle. 
The flare composition shall be thoroughly mixed and be uniformly 
compressed throughout to preclude variations of density which may 
adversely affect uniformity of its burning characteristics. The cap 
shall have a lap fit of not less than 25 mm (1 in.) over the end of the 
casing and flare composition to entirely and securely protect the 
exposed surface of the igniter button and end of flare composition and 
casing, and shall have an inner shoulder so constructed that it is 
mechanically impossible for the inner surface of the cap to come in 
contact with the igniter button. The cap shall be securely attached to 
the casing in such manner as to preclude its accidental detachment. The 
cap shall be provided on its top with a friction striking material which 
shall, by a pull of the tear strip, be entirely exposed for striking the 
friction igniter button. The igniter button shall be non-water soluble 
or be protected from moisture by a coating of some waterproof substance, 
and shall be raised or exposed in such manner as to provide positive 
ignition by the friction striker. The igniter button shall be firmly 
secured in or on the top of the flare composition; the arrangement shall 
be such that the ignition will be transmitted to the flare composition. 
The assembled flare, consisting of tear strip, cap, casing, and handle, 
shall be sealed and treated to protect the flare from deterioration by 
moisture. The protective waterproof coating shall be applied so none 
adheres to the friction striking surface. Special consideration will be 
given to alternate waterproofing of the signal by means of a water-
resistant coating on the signal plus packaging in a sealed plastic 
waterproof bag satisfactory to the Commandant.
    (d) Performance. Signals shall meet all the inspection and test 
requirements contained in Sec.  160.021-4.



Sec.  160.021-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
100 signals from which samples must be taken for testing for approval 
under Sec.  160.021-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this Chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.

[[Page 47]]

    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 30,000 signals. Lots must 
be numbered serially by the manufacturer. A new lot must be started 
with: (i) Any change in construction details, (ii) any change in sources 
of raw materials, or (iii) the start of production on a new production 
line or on a previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into construction of the signals and inspection of the finished signals, 
to determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.
    (3) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this Chapter must perform or supervise the inspections and tests under 
paragraph (b)(2) of this section at least 4 times a year, unless the 
number of lots produced in year is less than four. The inspections and 
tests must occur at least once during each quarterly period, unless no 
lots are produced during that period. If less than four lots are 
produced, the laboratory must perform or supervise the inspection and 
testing of each lot. In addition, the laboratory must perform or 
supervise the technical tests in paragraph (d) of this section at least 
once for every ten lots of signals produced, except that the number of 
technical tests must be at least one but not more than four per year. If 
a lot of signals tested by the independent laboratory is rejected, the 
laboratory must perform or supervise the inspections and tests of the 
reworked lot and the next lot of signals produced. The tests of each 
reworked lot and the next lot produced must not be counted for the 
purpose of meeting the requirement for the annual number of inspections 
and tests performed or supervised by the independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.021-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defects (Table 
160.021-4(c)(2)) is assigned a score (failure percent) in accordance 
with that table. In the case of multiple defects, only the score having 
the highest numerical value is assigned to that signal. If the sum of 
all the failure percents (cumulative failure percent) for the number of 
units in the sample is less than or equal to the accept criterion, the 
lot is accepted. If the cumulative failure percent falls between the 
accept and reject criteria, another sample is selected from the 
production lot and the operational tests are repeated. The cumulative 
failure percent of each sample tested is added to that of the previous 
samples to obtain the cumulative failure percent for all the signals 
tested (cumulative sample size). Additional samples are tested and the 
tests repeated until either the accept or reject criterion for the 
cumulative sample size is met. If any signal in the sample explodes when 
fired or ignited in a way that could burn or otherwise injure the person 
firing it, the lot is rejected without further testing. (This procedure 
is diagrammed in figure 160.021-4(c)).
    (2) Test procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water resistance. Immerse 
specimen horizontally with uppermost portion of the signal approximately 
25 mm (1 in.) below the surface of the water for a period of 24 hours. 
If the signal is protected by alternate waterproofing consisting of a 
water-resistant coating on the signal plus packaging in a sealed plastic 
waterproof bag, the 24-hour water immersion conditioning will be 
conducted while the signal is in the sealed plastic waterproof bag and 
will be followed by an additional immersion of the bare signal (i.e., 
after removal from the bag) 25 mm (1 in.) below the surface of the water 
for a period of 10 minutes.

[[Page 48]]

    (ii) Waterproofing of igniter button. Remove the cap from the test 
specimen. Place head of specimen without cap about 25 mm (1 in .) under 
the surface of water for approximately 5 minutes. Remove specimen from 
the water and wipe dry.
    (iii) Ignition and burning characteristics. Test specimens shall 
ignite and burn satisfactorily with uniform intensity when the 
directions on the signal are followed. Test specimens shall not ignite 
explosively in a manner that might be dangerous to the user or persons 
close by. The plug separating the flare composition from the handle 
shall in no case allow flame or hot gases to pass through it or between 
it and the casing in such manner as might burn the hand while holding 
the signal by the handle.
    (iv) Burning time. The burning time of a specimen shall be obtained 
by stop watch measurements from the time a distinct sustained flame is 
emitted until it ceases. Test specimens shall burn in air not less than 
2 minutes.

------------------------------------------------------------------------

    (d) Technical tests. Three signals must be subjected to each of the 
following tests. Two of the three signals must pass each test in order 
for the lot of signals to be accepted.
    (1) Underwater burning. Condition each sample in accordance with 
paragraph (c)(2)(i) of this section. Ignite specimen and let it burn 
about 5 seconds in air. Submerge the burning signal in water in a 
vertical position with head down. Obtain under water burning time by 
stop watch measurement from time of submersion until distinct, sustained 
flame emission ceases. The test specimen shall burn under water not less 
than 5 seconds when subjected to this test.

    (2) Bending strength. Place the specimen on supports 15 cm (6 in.) 
apart. Attach a weight of 35 kg (77 lb.) to a length of wire. Hang the 
weight from the supported signal by looping the wire around the signal 
approximately

[[Page 50]]

equidistant from the two points of support. Let the weight hang 
approximately 5 minutes. The test specimen shall not deflect more than 7 
mm (1/4 in.), nor shall the joint between the casing and the handle 
fail, when subjected to this test.
    (3) Tensile strength. Place the specimen in a chuck firmly holding 
it about 13 mm (1/2 in.) below the cap. Attach a weight of 35 kg (77 
lb.) to a length of wire. Hang the weight from the supported signal by 
looping the wire through a hole bored perpendicular to and through the 
axis of the handle. Let the weight hang approximately 5 minutes. The 
test specimen shall not show noticeable distortion, nor shall the joint 
between the casing and handle fail, when subjected to this test.
    (4) Luminous intensity. The luminous intensity of each specimen 
tested shall be measured by a visual photometer or equivalent 
photometric device, while the specimen is supported in a horizontal 
position and the photometer is at right angles to the axis of the 
specimen. Visual luminous intensity readings shall be observed and 
recorded at approximately 20 second intervals during the burning of the 
specimen. The minimum photometric distance shall be 3 m (10 ft.). 
Recording photometers shall have a chart speed of at least 25 mm (1 in.) 
per minute. The luminous intensity of specimen shall be computed as the 
arithmetical average of the readings recorded. The average luminous 
intensity of a test specimen shall be not less than 500 candela. The 
burning time of a specimen shall be obtained by stop watch measurements 
from the time distinct, sustained flame is emitted until it ceases. Test 
specimens shall burn in air not less than 2 minutes.
    (5) Elevated temperature, humidity and storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for 10 days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during the 72-hour conditioning period. 
(Total of 24 hours on and 48 hours off.) The signal shall not ignite or 
decompose during this conditioning. The signal shall ignite and operate 
satisfactorily following this conditioning.
    (6) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signals shall not 
ignite or undergo marked decomposition.
    (7) Chromaticity. The color of the burning signal must be vivid red 
as defined by sections 13 and 14 of the ``Color Names Dictionary.'' Two 
identical test plates of white cardboard about 30 cm x 60 cm 
(12 x 24) are used. Except for a negligible amount 
of stray daylight, the first test plate is illuminated by light from the 
specimen placed at a distance of about 1.5 m (5 ft.). The second test 
plate is illuminated only by light from an incandescent lamp operated at 
a color temperature close to 2,848 [deg]K at a distance of about 30 cm 
(1 ft.). The first plate is viewed directly, the second through 
combinations of Lovibond red, yellow, and blue glasses selected so as to 
approximate a chromaticity match. By separating the test plates by a 
wide unilluminated area (subtending at the observer about 45[deg]), it 
is possible to make accurate determinations of chromaticity in terms of 
the 1931 CIE Standard Observer and Coordinate System, in spite of 
fluctuations in luminous intensity of the specimen by factors as high as 
2 or 3. The CIE coordinates are converted to the Munsell notation which 
is cross-referenced to the color name in Section 13 of the ``Color Names 
Dictionary'' (see the discussion in section 10 of ``The Universal Color 
Language'').
    (8) Heptane ignition. (i) A metal pan must be used to hold a layer 
of water at least 12mm (\1/2\ in.) deep with a layer of technical grade 
heptane on top of the water. The pan must be at least 1 m (39 in.) 
square with sides extending between 175 mm (7 in.) and 200 mm (8 in.) 
above the surface of the water. The amount of heptane used to form the 
layer must be 2.0 liters per square

[[Page 51]]

meter of pan area (6.25 fluid ounces per square foot).
    (ii) The test must be conducted in a draft-free location. The 
ambient temperature, the temperature of the water, and the temperature 
of the heptane must all be between 20 [deg]C (68 [deg]F) and 25 [deg]C 
(77 [deg]F) at the time of the test.
    (iii) The signal under test must be held with the flame end pointing 
upward at an angle of approximately 45[deg], 1.2 m (4 ft.) directly 
above the center of the pan. The signal must be ignited as soon as the 
heptane is observed to spread out over the water in continuous layer. 
The signal must be allowed to burn completely, and must remain in 
position until it has cooled.
    (iv) The heptane must not be ignited by the flare or by material 
from the flare.

    Caution: Heptane ignites rapidly and burns vigorously. The flare 
should be remotely ignited and all personnel should stay clear of the 
test pan while the flare is burning and while any part of it remains 
hot.

Sec.  160.021-5  Labeling and marking.

    (a) Labeling. Each hand red flare distress signal shall bear a label 
securely affixed thereto, showing in clear, indelible black lettering on 
a red background, the following wording and information:

                  (Company brand or style designation)

                     Hand Red Flare Distress Signal

                   500 Candela--2 Minutes Burning Time

               Use Only When Aircraft or Vessel Is Sighted

    Directions: Pull tape over top of cap. Remove cap and ignite flare 
by rubbing scratch surface on top of cap sharply across igniter button 
on head of signal.
    Caution: Stand with back to wind and point away from body when 
igniting or flare is burning.
    Service Life Expiration Date (Month and year to be inserted by 
manufacturer) (Month and year manufactured) (Lot No.__). Manufactured by 
(Name and address of manufacturer). U.S. Coast Guard Approval No.__

    (b) Marking of expiration date. The expiration date must be not more 
than 42 months from the date of manufacture.
    (c) Other marking. (1) There shall be die-stamped, in the side of 
the wooden handle in figures not less than 3 mm (C\1/8\ in.) high, 
numbers indicating the month and year of manufacture, thus: ``6-54'' 
indicating June, 1954.
    (2) In addition to any other marking placed on the smallest packing 
carton or box containing hand red flare distress signals, such cartons 
or boxes shall be plainly and permanently marked to show the service 
life expiration date, date of manufacture, and lot number.
    (3) The largest carton or box in which the manufacturer ships 
signals must be marked with the following or equivalent words: ``Keep 
under cover in a dry place.''

    Note: Compliance with the labeling requirements of this section does 
not relieve the manufacturer of the responsibility of complying with the 
label requirements of 15 U.S.C. 1263, the Federal Hazardous Substances 
Act.



Sec.  160.021-6  Container.

    (a) General. Containers for stowage of hand red flare distress 
signals in lifeboats and life rafts on merchant vessels are not required 
to have specific approval or to be of special design, but they shall 
meet the following test for watertightness when closed, and shall be 
capable of being opened and reclosed hand-tight to meet the same 
watertightness test. The materials shall be copper, brass, bronze, or 
equally corrosion-resistant to salt water and spray. The type container 
illustrated by Figure Number 160.021-6(a) is recommended for most 
purposes.
    (b) Watertightness test for containers. Whenever a question arises 
as to the watertightness of a container, the following test may be made 
to determine whether it is satisfactory in this respect. Open the 
container, remove the contents, insert colored blotting paper as a 
lining, re-close container as tightly as possible by hand (no wrenches 
or special tools permitted), submerge container with top about 30 cm (1 
ft.) below the surface of the water for two hours, remove container from 
water, wipe off excess moisture on outside,

[[Page 52]]

then open the container and examine the blotting paper and entire 
interior for evidence of moisture penetration. If any moisture or water 
is evidenced, the container is not satisfactory.

[[Page 53]]


    (c) Marking of container. Containers shall be embossed or bear a 
brass or equivalent corrosion-resistant nameplate, or otherwise be 
suitably and permanently marked, to plainly show in letters not less 
than 13 mm (\1/2\ in.) high the following wording: ``HAND RED FLARE 
DISTRESS SIGNALS''. No additional marking which might cause confusion as 
to the contents shall be permitted. The vessel's name ordinarily is 
painted or branded on equipment such as this container, and nothing in 
this subpart shall be construed as prohibiting same.

Sec.  160.022-2  Type.

    (a) Floating orange smoke distress signals, specified by this 
subpart shall be of one type which shall consist essentially of an outer 
container, ballast, an air chamber, an inner container, the smoke 
producing composition, and an igniter mechanism. Alternate arrangements 
which conform to the performance requirements of this specification will 
be given special consideration.
    (b) [Reserved]



Sec.  160.022-3  Materials, workmanship, construction, and 
performance requirements.

    (a) Materials. The materials shall conform strictly to the 
specifications and drawings submitted by the manufacturer and approved 
by the Commandant. Metal for containers shall be not less than 0.5 mm 
(0.020 in.) in thickness. Other dimensions or materials may be 
considered upon special request when presented with supporting data. 
Igniter systems shall be corrosion-resistant metal. The combustible 
material shall be of such nature that it will not deteriorate during 
long storage, nor when subjected to frigid or tropical climates, or 
both.
    (b) Workmanship. Floating orange smoke distress signals shall be of 
first class workmanship and shall be free from imperfections of 
manufacture affecting their appearance or that may affect their 
serviceability.
    (c) Construction. The outer container shall be of a size suitable 
for its intended use. All sheet metal seams should be hook-jointed and 
soldered. The whole container shall be covered with two coats of 
waterproof paint or equivalent protection system. The igniter mechanism 
shall be simple to operate and provide ignition in most unfavorable 
weather. The mechanism shall be protected with a watertight

[[Page 54]]

cover having a finish which is corrosion-resistant to salt water and 
spray. The cover shall be easily and quickly removable by hand without 
the use of tools. If attachment of the cover is by formed screw threads, 
it shall be of such construction or material to prevent rusting or 
corrosion and will not back off and loosen under shipboard vibration.
    (d) Performance. Signals shall meet all the inspection and test 
requirements contained in Sec.  160.022-4.



Sec.  160.022-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
100 signals from which samples must be taken for testing for approval 
under Sec.  160.022-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.
    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 30,000 signals. Lots must 
be numbered serially by the manufacturer. A new lot must be started 
with:
    (i) Any change in construction details,
    (ii) Any change in sources of raw materials, or
    (iii) The start of production on a new production line or on a 
previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into construction of the signals and inspection of the finished signals, 
to determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.
    (3) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this chapter must perform or supervise the inspections and tests under 
paragraph (b)(2) of this section at least 4 times a year, unless the 
number of lots produced in a year is less than four. The inspections and 
tests must occur at least once during each quarterly period, unless no 
lots are produced during that period. If less than four lots are 
produced, the laboratory must perform or supervise the inspection and 
testing of each lot. In addition, the laboratory must perform or 
supervise the technical tests in paragraph (d) of this section at least 
once for every ten lots of signals produced, except that the number of 
technical tests must be at least one but not more than four per year. If 
a lot of signals tested by the independent laboratory is rejected, the 
laboratory must perform or supervise the inspections and tests of the 
reworked lot and the next lot of signals produced. The tests of each 
reworked lot and the next lot of signals must not be counted for the 
purpose of meeting the requirement for the annual number of inspections 
and tests performed or supervised by the independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.022-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defects (Table 
160.022-4(c)(2)) is

[[Page 55]]

assigned a score (failure percent) in accordance with that table. In the 
case of multiple defects, only the score having the highest numerical 
value is assigned to that signal. If the sum of all the failure percents 
(cumulative failure percent) for the number of units in the sample is 
less than or equal to the accept criterion, the lot is accepted. If this 
sum is equal to or more than the reject criterion the lot is rejected. 
If the cumulative failure percent falls between the accept and reject 
criteria, another sample is selected from the production lot and the 
operational tests are repeated. The cumulative failure percent of each 
sample tested is added to that of the previous samples to obtain the 
cumulative failure percent for all the signals tested (cumulative sample 
size). Additional samples are tested and the tests repeated until either 
the accept or reject criterion for the cumulative sample size is met. If 
any signal in the sample explodes when fired or ignited in a way that 
could burn or otherwise injure the person firing it, the lot is rejected 
without further testing. (This procedure is diagrammed in figure 
160.022-4(c).)
    (2) Test Procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water-resistance. Immerse 
specimens horizontally with uppermost portion of the signal 
approximately 25 mm (1 in.) below the surface of the water for a period 
of 24 hours.
    (ii) Smoke emitting time. Ignite specimen according to the 
directions printed on the signal and place signal in tub or barrel of 
water. The smoke emitting time of a specimen shall be obtained by stop 
watch measurements from the time of distinct, sustained smoke emission 
until it ceases. The watch shall be stopped during periods of flame 
emission. The smoke emitting time for a specimen shall be not less than 
4 minutes.
    (iii) Ignition and smoke emitting characteristics. Test specimens 
shall ignite and emit smoke properly when the directions on the signal 
are followed. Test specimens shall not ignite explosively in a manner 
that might be dangerous to the user or persons close by. Test specimens 
shall emit smoke at a uniform rate while floating in calm to rough 
water. Signals should be so constructed that water submerging the signal 
in moderately heavy seas will not cause it to become inoperative.

    (d) Technical tests. Three signals must be subjected to each of the 
following tests. Two of the three signals must pass the test in order 
for the lot of signals to be accepted.

[[Page 57]]

    (1) Smoke emission in waves. The signal shall be ignited and thrown 
overboard under conditions where the waves are at least 30 cm (1 ft.) 
high. The smoke emitting time must be at least 4 minutes and the signal 
shall float in such a manner that the signal shall function properly 
during this test. Failure to pass this test shall be cause for the lot 
to be rejected.
    (2) Underwater smoke emission. Condition each sample in accordance 
with paragraph (c)(2)(i) of this section. Ignite specimen and let it 
burn about 15 seconds in air. Submerge the burning signal in water in a 
vertical position with head down. Obtain underwater smoke emission time 
by stop watch measurements from time of submersion until distinct, 
sustained smoke emission ceases. The test specimen shall emit smoke 
underwater not less than 15 seconds when subjected to this test.
    (3) Elevated temperature, humidity, and storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for ten days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during 72-hour conditioning period. (Total of 
24 hours on and 48 hours off). The signal shall not ignite or decompose 
during this conditioning. The signal shall ignite and operate 
satisfactorily following this conditioning.
    (4) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signal shall not 
ignite or undergo marked decomposition.
    (5) Susceptibility to explosion. Remove smoke composition from 
signal and punch a small hole in the composition. Insert a No. 6 
commercial blasting cap. Ignite the cap. The test specimen shall not 
explode or ignite.
    (6) Corrosion resistance. Expose the complete specimen with cover 
secured hand-tight to a finely divided spray of 20 percent by weight 
sodium chloride solution at a temperature between 32 [deg]C and 38 
[deg]C (90 [deg]F and 100 [deg]F) for 100 hours. The container and cap 
must not be corroded in any fashion that would impair their proper 
functioning.
    (7) Color of smoke. Ignite specimen in the open air in daytime 
according to the directions printed on the signal, and determine the 
smoke color by direct visual comparison of the unshadowed portions of 
the smoke with a color chart held so as to receive the same daylight 
illumination as the unshadowed portions of the smoke. The color of the 
smoke must be orange as defined by Sections 13 and 14 of the ``Color 
Names Dictionary'' (colors 34-39 and 48-54).
    (8) Volume and density of smoke. The test specimen shall show less 
than 20 percent transmission for not less than 3 minutes when measured 
with apparatus having a light path of 19 cm (7\1/2\ in.), an optical 
system aperture of + 3.7 degrees, and an entrance air flow of 18.4m\3\ 
per minute (650 cu. ft. per minute), such apparatus to be as described 
in National Bureau of Standards Report No. 4792.



Sec.  160.022-5  Marking.

    (a) Directions for use. Each floating orange smoke distress signal 
shall be plainly and indelibly marked in black lettering not less than 3 
mm (\1/8\ in.) high ``Approved for daytime use only'', and in black 
lettering not less than 5 mm (\3/16\ in.) high with the word 
``Directions''. Immediately below shall be similarly marked in black 
lettering not less than 3 mm (\1/8\ in.) high: ``1. Use Only When 
Aircraft or Vessel Is Sighted''. Then in numbered paragraphs, in similar 
lettering, there shall follow in simply and easily understood wording, 
instructions to be followed to make the device operative. Pasted-on 
labels are not acceptable.
    (b) Other markings. (1) There shall be embossed or die-stamped, in 
the outer container in figures not less than 5 mm (\3/16\ in.) high, 
numbers, indicating the month and year of manufacture, thus: ``6-54'' 
indicating June 1954. The outer container shall also be plainly and 
indelibly marked with the commercial designation of the signal, the 
words

[[Page 58]]

``Floating Orange Smoke Distress Signal'', name and address of the 
manufacturer, the Coast Guard Approval No., the service life expiration 
date (month and year to be entered by the manufacturer), the month and 
year of manufacture and the lot number.
    (2) In addition to any other marking placed on the smallest packing 
carton or box containing floating orange smoke distress signals, such 
cartons or boxes shall be plainly and indelibly marked to show the 
service life expiration date, the month and year of manufacture, and the 
lot number.
    (3) The largest carton or box in which the manufacturer ships 
signals must be marked with the following or equivalent words: ``Keep 
under cover in a dry place.''
    (c) Marking of expiration date. The expiration date must be not more 
than 42 months from the date of manufacture.

    Note: Compliance with the labeling requirements of this section does 
not relieve the manufacturer of the responsibility of complying with the

Sec.  160.024-2  Type.

    (a) Pistol-projected parachute red flare distress signals specified 
by this subpart shall be of one type which shall consist essentially of 
a cartridge having centered primer, propelling charge, and projectile 
consisting of a case, delay element, expelling charge, and pyrotechnic 
candle attached to a parachute by shroud lines; the cartridge to be of 
such dimensions that it can be fitted into and fired from a signal 
pistol with chamber and bore dimensions within the limits provided by 
Figure 160.028-2(a) of subpart 160.028 of this chapter.
    (b) [Reserved]



Sec.  160.024-3  Materials, workmanship, construction, and
performance requirements.

    (a) Materials. The materials used in pistol-projected parachute red 
flare distress signals shall conform strictly to the specifications and 
drawings submitted by the manufacturer and approved by the Commandant. 
In general, all metallic parts shall be corrosion-resistant or properly 
protected against corrosion.
    (b) Workmanship. Pistol-projected parachute red flare distress 
signals shall be of first class workmanship and shall be free from 
imperfections of manufacture affecting their appearance or that may 
affect their serviceability.
    (c) Construction. The exterior case of the cartridge shall be made 
of suitable metal and shall protect against the entrance of moisture. 
The projectile case and delay element shall be so constructed as to 
prevent any possibility of the propelling charge blowing by and causing 
premature ejection of the projectile contents. The shoulder of the base 
of the cartridge shall be between 2.29 mm (0.090 in.) and 2.67 mm (0.015 
in.) in thickness. The centered primer shall be set below the surface of 
the base between 0.25 mm (0.010 in.) and 0.50 mm (0.020 in.).
    (d) Performance. Signals shall meet all of the inspection and test 
requirements contained in Sec.  160.024-4.



Sec.  160.024-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
100 signals from which samples must be taken for testing for approval 
under Sec.  160.024-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.
    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 30,000 signals. Lots must 
be numbered serially by the manufacturer. A new lot must be started 
with: (i) Any change in construction details, (ii) any change in sources 
of raw materials, or (iii) the start of production on a new production 
line or on a previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into construction of the signals and inspection of the finished signals, 
to determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.
    (3) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this chapter must perform or supervise the inspections and

[[Page 61]]

tests under paragraph (b)(2) of this section at least 4 times a year, 
unless the number of lots produced in a year is less than four. The 
inspections and tests must occur at least once during each quarterly 
period, unless no lots are produced during this period. If less than 
four lots are produced, the laboratory must perform or supervise the 
inspection and testing of each lot. In addition, the laboratory must 
perform or supervise the technical tests in paragraph (d) of this 
section at least once for every ten lots of signals produced, except 
that the number of technical tests must be at least one but not more 
than four per year. If a lot of signals tested by the independent 
laboratory is rejected, the laboratory must perform or supervise the 
inspections and tests of the reworked lot and the next lot of signals 
produced. The tests of each reworked lot and the next lot produced must 
not be counted for the purpose of meeting the requirement for the annual 
number of inspections and tests performed or supervised by the 
independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.024-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defects. (Table 
160.024-4(c)(2)) is assigned a score (failure percent) in accordance 
with the table. In the case of multiple defects, only the score having 
the highest numerical value is assigned to that signal. If the sum of 
all the failure percents (cumulative failure percent) for the number of 
units in the sample is less than or equal to the accept criterion, the 
lot is accepted. If this sum is equal to or more than the reject 
criterion the lot is rejected. If the cumulative failure percent falls 
between the accept and reject criteria, another sample is selected from 
the production lot and the operational tests are repeated. The 
cumulative failure percent of each sample tested is added to that of the 
previous samples to obtain the cumulative failure percent for all the 
signals tested (cumulative sample size). Additional samples are tested 
and the tests repeated until either the accept or reject criterion for 
the cumulative sample size is met. If any signal in the sample explodes 
when fired or ignites in a way that could burn or otherwise injure the 
person firing it, the lot is rejected without further testing. (This 
procedure is diagrammed in figure 160.024-4(c).)
    (2) Test procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water resistance. Immerse 
specimen horizontally with uppermost portion of the signal approximately 
25 mm (1 in.) below the surface of the water for a period of 24 hours.
    (ii) Firing and operating characteristics. Signals shall fire and 
operate satisfactorily when shot from a pistol of the type described in 
subpart 160.028. The parachute and pyrotechnic candle shall be ejected 
at approximately the maximum altitude reached by the projectile case. 
The parachute shall open and properly suspend the pyrotechnic candle 
without fouling. The pyrotechnic candle shall burn with uniform 
intensity and without damaging the parachute, shrouds, or leader line.
    (iii) Altitude. The altitude reached by a signal is considered to be 
the height at which the parachute and pyrotechnic candle are ejected 
from the projectile case, as determined by visual observation against an 
object of known height, such as a tower or balloon, or by triangulation 
from two or more points of observation, or by other method satisfactory 
to the Commandant. The altitude reached shall be not less than 45 m (150 
ft.).
    (iv) Rate of descent. The rate of descent of a signal is considered 
to be the calculated average rate obtained by dividing the altitude by 
the time of descent to the surface. The rate of descent shall not exceed 
1.8 m (6 ft.) per second.
    (v) Burning time. The burning time of the pyrotechnic candle shall 
be obtained by stop watch measurement from the time distinct, sustained 
flame is emitted until it ceases. The burning time shall be not less 
than 30 seconds.

    (d) Technical tests. Three signals must be subjected to each of the 
following tests. Two of the three signals must pass each test in order 
for the lot of signals to be accepted.
    (1) Luminous intensity. The luminous intensity of each pyrotechnic 
candle tested shall be measured by a visual photometer or equivalent 
photometric device while the specimen is supported in a horizontal 
position and the photometer is at right angles to the axis of

[[Page 64]]

the specimen. Visual luminous intensity readings shall be observed and 
recorded at approximately 5-second intervals during the burning of the 
specimen. The minimum photometric distance shall be 3 m (10 ft.). 
Recording photometers shall have a chart speed of at least 10 cm (4 in.) 
per minute. The luminous intensity of the specimen shall be computed as 
the arithmetical average of the readings recorded. The average luminous 
intensity of a specimen shall be not less than 20,000 candela.
    (2) Elevated temperature, humidity, and storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for 10 days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during the 72-hour conditioning period. 
(Total of 24 hours on and 48 hours off.) The signal shall not ignite or 
decompose during this conditioning. The signal shall fire and operate 
satisfactorily following this conditioning.
    (3) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signal shall not 
ignite or undergo marked decomposition.
    (4) Chromaticity. The color of the burning signal must be vivid red 
as defined by Sections 13 and 14 of the ``Color Names Dictionary.'' Two 
identical test plates of white cardboard about 30 cm x 60 cm 
(12 x 24) are used. Except for a negligible amount 
of stray daylight, the first test plate is illuminated by light from the 
specimen placed at a distance of about 1.5 cm (5 ft.). The second test 
plate is illuminated only by light from an incandescent lamp operated at 
a color temperature close to 2,848[deg] K at a distance of about 30 cm 
(1 ft.). The first plate is viewed directly, the second through 
combinations of lovibond red, yellow, and blue glasses selected so as to 
approximate a chromaticity match. By separating the test plates by a 
wide unilluminated area (subtending at the observer about 45[deg]), it 
is possible to make accurate determinations of chromaticity in terms of 
the 1931 CIE Standard Observer and Coordinate System, in spite of 
fluctuations in luminous intensity of the specimen by factors as high as 
2 or 3. The CIE coordinates are converted to the Munsell notation which 
is cross-referenced to the color name in Section 13 of the ``Color Names 
Dictionary'' (see the discussion in section 10 of ``the Universal Color 
Language'').

            Subpart 160.027_Life Floats for Merchant Vessels

    Source: CGD 79-167, 47 FR 41376, Sept. 20, 1982, unless otherwise 
noted.



Sec.  160.027-2  Type.

    (a) Each life float must meet the requirements in subpart 160.010 of 
this chapter for a peripheral body type buoyant apparatus designed so 
that persons supported are only partially immersed (180 N (40 lb.) of 
buoyancy per person required).
    (b) [Reserved]



Sec.  160.027-3  Additional requirements for life floats.

    (a) Each life float must have a platform designed to drop through 
the center of the float, whichever way the life float is floating. A 
typical arrangement is shown in Figure 160.027-3(a).
    (b) The platform must meet the requirements of one of the following 
paragraphs:

[[Page 68]]

[GRAPHIC] [TIFF OMITTED] TC03MR91.008

    (1) A lattice type platform must be of western red cedar, port 
orford cedar, sitka spruce, northern white pine, or southern cypress 
slats constructed on an oak frame. The slats must have nominal cross-
section dimensions not less than 90 mm (3\5/8\ in.) by 9.5 mm (\3/8\ 
in.). The frame members must have

[[Page 69]]

nominal cross-section dimensions not less than 100 mm (4 in.) by 12.5 mm 
(\1/2\ in.). The space between adjacent slats must not exceed the width 
of the slats. The space between each frame member and the adjacent slat 
must not exceed twice the width of the slats. The platform must be 
riveted together at each intersection of--
    (i) Frame members,
    (ii) Slats, and
    (iii) Frame members and slats.
    (2) A plywood platform must be made of exterior or marine type 
plywood with surfaces that are either ``A'' or ``B'' grade as commonly 
designated in the plywood industry. Holes 35 mm (1\3/8\ in.) to 50 mm (2 
in.) in diameter must be drilled through the platform. The number of 
holes must be at least the number equal to (L-25) (W-25)/225, where L is 
the length of the platform in cm and W is the width of the platform in 
cm. (The formula is (L-10)(W-10)/36 where L and W are measured in 
inches.) The thickness of the plywood must be at least--
    (i) 12.5 mm (\1/2\ in.) for life floats of 10 persons capacity and 
under,
    (ii) 16 mm (\5/8\ in.) for life floats between 11 and 25 persons 
capacity inclusive, and
    (iii) 19 mm (\3/4\ in.) for life floats of 26 persons capacity and 
over.
    (3) A platform of construction differing from that described in 
either (1) or (2) of this paragraph will be approved if it has holes to 
permit the passage of water and if it passes the tests in Sec.  160.027-
7. The number of holes must be the same as required for a plywood 
platform. If the platform is netting on a frame, the netting must be 
constructed of cordage with a breaking strength of at least 1600 N (355 
lb.). The netting must be constructed on not more than 5 cm (2 in.) 
centers and must be knotted together at each point where the lines 
intersect.
    (c) Each platform must be of a material that is resistant to 
deterioration by exposure to weather or must have a surface that 
protects it from deterioration by exposure to weather. For a wood 
platform, this surface must be at least two coats of water resistant 
spar varnish, or two coats of marine paint.
    (d) Each part of the platform, including surfaces, edges, and rivets 
must be smooth and must not have cutting edges, points, or splinters 
which would be dangerous for bare feet.
    (e) The platform must be arranged so that under normal stowed 
conditions, it can be retained in the center of the float and can be 
readily released from this position for use.
    (f) The platform must be suspended from the body of the float by a 
net or an equivalent arrangement, which when fully extended, holds the 
top of the platform approximately 900 mm (36 in.) below the center of 
the float body.
    (1) The net must be constructed of cordage with a minimum breaking 
strength of 1600 N (355 lb.). The net must be attached to the platform 
through holes on centers that do not exceed 165 mm (6\1/2\ in.).
    (2) If the platform is suspended from the body of the float by an 
arrangement other than a net as described in paragraph (c)(1) of this 
section, the arrangement must be of equivalent to the net in terms of 
strength, resistance to tangling, and allowing the platform to freely 
pass through the center of the life float body.



Sec.  160.027-7  Pre-approval tests for alternate platform designs.

    (a) The tests in this section are for life float platforms that do 
not meet the requirements of either Sec.  160.027-3(b) (1) or (2).
    (b) The float body must be supported so that the platform is 
suspended in the air by the net or equivalent supporting arrangement. 
The platform must be loaded evenly with a weight equal to 60 percent of 
the weight of the total number of persons for which the float is to be 
rated, assuming a weight of 75 kg (165 lb.) per person. The weight must 
be allowed to remain on the platform for ten minutes after which it is 
removed. The supporting arrangement and platform must not show any 
evidence of damage or permanent deformation as a result of this test.
    (c) The float body must be supported so that the platform is 
suspended in the air by the net or equivalent supporting arrangement. A 
bag of sand, shot or similar granular material weighing 90 kg (200 lb.) 
must be dropped onto the center of the platform

[[Page 70]]

from a height of 3 m (10 ft.). The supporting arrangement and platform 
must not show any damage that would affect the serviceability of the 
float or platform.
    (d) As part of the buoyancy test required in Sec.  160.010-7(e) of 
this chapter, the platform must be loaded with weights equal to \1/2\ 
the rated capacity of the float. There must be no damage to the 
supporting arrangement or platform as a result of this test.

    Note: Since the weights on the platform will be submerged during 
this test, allowance must be made for the displacement of the submerged 
weights. The weight required is calculated by the formula W = (18d)/(d-
4895), where W is the required submerged weight per person (in kg) and d 
is the density of the material (in kg/m\3\). (In customary U.S. units, 
the formula is W = 40d)/(d-63) where W is in lb. and d is in lb./
ft.\3\).

    (c) Approval to incorporate by reference the material listed in this 
section was obtained from the Director of the Federal Register on 
November 1, 1979. The material is on file in the Federal Register 
library.



Sec.  160.036-2  Type.

    (a) Handheld rocket-propelled parachute red flare distress signals 
specified by this subpart shall be of one type which shall consist 
essentially of a completely self-contained device which can be fired 
from the hand to provide a rocket-propelled parachute red flare distress 
signal.
    (b) [Reserved]



Sec.  160.036-3  Materials, workmanship, construction and performance
requirements.

    (a) Materials. The materials used in handheld rocket-propelled 
parachute red flare distress signals shall conform strictly to the 
specifications and drawings submitted by the manufacturer and approved 
by the Commandant. In general, all exposed parts shall be corrosion-
resistant or properly protected against corrosion.
    (b) Workmanship. Handheld rocket-propelled parachute red flare 
distress signals shall be of first class workmanship and shall be free 
from imperfections of manufacture affecting their appearance or that may 
affect their serviceability.
    (c) Construction. The exterior case of the cartridge shall be made 
of a suitable metal and shall protect against the entrance of moisture. 
The construction shall be such that the parachute and pyrotechnic candle 
will be

[[Page 76]]

expelled at approximately the maximum altitude reached.
    (d) Performance. Signals shall meet all of the inspection and test 
requirements contained in Sec.  160.036-4.



Sec.  160.036-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
100 signals from which samples must be taken for testing for approval 
under Sec.  160.036-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this Subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.
    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 30,000 signals. Lots must 
be numbered serially by the manufacturer. A new lot must be started 
with:
    (i) Any change in construction details,
    (ii) Any changes in sources of raw materials, or
    (iii) The start of production on a new production line or on a 
previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into construction of the signals and inspection of the finished signals, 
to determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.
    (3) Inspections and test by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this chapter must perform or supervise the inspections and tests under 
paragraph (b)(2) of this section at least 4 times a year, unless the 
number of lots produced in a year is less than four. The inspections and 
tests must occur at least once during each quarterly period, unless no 
lots are produced during this period. If less than four lots are 
produced, the laboratory must perform or supervise the inspection and 
testing of each lot. In addition, the laboratory must perform or 
supervise the technical tests in paragraph (d) of this section at least 
once for every ten lots of signals produced, except that the number of 
technical tests must be at least one but not more than four per year. If 
a lot of signals tested by the independent laboratory is rejected, the 
laboratory must perform or supervise the inspections and tests of the 
reworked lot and the next lot of signals produced. The tests of each 
reworked lot and the next lot produced must not be counted for the 
purpose of meeting the requirement for the annual number of inspections 
and tests performed or supervised by the independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.036-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defects (Table 
160.036-4(c)(2)) is assigned a score (failure percent) in accordance 
with that table. In the case of multiple defects, only the score having 
the highest numerical value is assigned to that signal. If the sum of 
all the failure percents (cumulative failure percent) for the number of 
units in the sample is less than or equal to the accept criterion, the 
lot is accepted. If this sum is equal to or more than the

[[Page 77]]

reject criterion the lot is rejected. If the cumulative failure percent 
falls between the accept and reject criteria, another sample is selected 
from the production lot and the operational tests are repeated. The 
cumulative failure percent of each sample tested is added to that of the 
previous samples to obtain the cumulative failure percent for all the 
signals tested (cumulative sample size). Additional samples are tested 
and the tests repeated until either the accept or reject criterion for 
the cumulative sample size is met. If any signal in the sample explodes 
when fired or ignites in a way that could burn or otherwise injure the 
person firing it, the lot is rejected without further testing. (This 
procedure is diagrammed in figure 160.036-4(c)).
    (2) Test procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water resistant. Immerse 
specimen horizontally with uppermost portion of the signal approximately 
25 mm (1 in.) below the surface of the water for a period of 24 hours.
    (ii) Firing and operating characteristics. Signals shall fire and 
operate satisfactorily when the manufacturer's directions are followed. 
The parachute and pyrotechnic candle shall be ejected at approximately 
the maximum altitude reached by the projectile case. The parachute shall 
open and properly suspend the pyrotechnic candle without fouling. The 
pyrotechnic candle shall burn with uniform intensity and without 
damaging the parachute, shrouds, or leader line.
    (iii) Altitude. The altitude reached by a signal is considered to be 
the height at which the parachute and pyrotechnic candle are ejected 
from the projectile case, as determined by visual observation against an 
object of known height, such as a tower or balloon, or by triangulation 
from two or more points of observation, or by other method satisfactory 
to the Commandant. The altitude reached shall be not less than 150 m 
(500 ft.).
    (iv) Rate of descent. The rate of descent of a signal is considered 
to be the calculated average rate obtained by dividing the altitude by 
the time of descent to the surface. The rate of descent shall not exceed 
4.5 m (15 ft.) per second.
    (v) Burning time. The burning time of the pyrotechnic candle shall 
be obtained by stop watch measurement from the time a distinct, 
sustained flame is emitted until it ceases. The burning time shall be 
not less than 30 seconds.

    (d) Technical tests. Three signals must be subjected to each of the 
following tests. Two of the three signals must pass each test in order 
for the lot of signals to be accepted.
    (1) Luminous intensity. The luminous intensity of each pyrotechnic 
candle

[[Page 80]]

tested shall be measured by a visual photometer or equivalent 
photometric device while the specimen is supported in a horizontal 
position and the photometer is at right angles to the axis of the 
specimen. Visual luminous intensity readings shall be observed and 
recorded at approximately 5-second intervals during the burning of the 
specimen. The minimum photometric distance shall be 3 m (10 ft.). 
Recording photometers shall have a chart speed of at least 10 cm (4 in.) 
per minute. The luminous intensity of the specimen shall be computed as 
the arithmetical average of the readings recorded. The average luminous 
intensity of a specimen shall be not less than 20,000 candela.
    (2) Elevated temperature, humidity, and storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for ten days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during the 72-hour conditioning period. 
(Total of 24 hours on and 48 hours off.) The signal shall not ignite or 
decompose during this conditioning. The signal shall fire and operate 
satisfactorily following this conditioning.
    (3) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signal shall not 
ignite or undergo marked decomposition.
    (4) Chromaticity. The color of the burning signal must be vivid red 
as defined by Sections 13 and 14 of the ``Color Names Dictionary.'' Two 
identical test plates of white cardboard about 30 cm x 60 cm 
(12 x 24) are used. Except for a negligible amount 
of stray daylight, the first test plate is illuminated by light from the 
specimen placed at a distance of about 1.5 m (5 ft.). The second test 
plate is illuminated only by light from an incandescent lamp operated at 
a color temperature close to 2,848[deg] K at a distance of about 30 cm 
(1 ft.). The first plate is viewed directly, the second through 
combinations of Lovibond red, yellow, and blue glasses selected so as to 
approximate a chromaticity match. By separating the test plates by a 
wide unilluminated area (subtending at the observer about 45[deg]), it 
is possible to make accurate determinations of chromaticity in terms of 
the 1931 CIE Standard Observer and Coordinate System, in spite of 
fluctuations in luminous intensity of the specimen by factors as high as 
2 or 3. The CIE coordinates are converted to the Munsell notation which 
is cross-referenced to the color name in Section 13 of the ``Color Names 
Dictionary'' (see the discussion in Section 10 of ``The Universal Color 
Language'').

Sec.  160.036-5  Marking.

    (a) General. Each hand-held rocket-propelled parachute red flare 
distress signal shall be legibly marked or labeled as follows:

    (Company brand or style designation) Hand-Held Rocket-Propelled 
Parachute Red Flare Distress Signal--20,000 candela--30 seconds burning 
time. Use Only When Aircraft or Vessel Is Sighted. Directions--(In 
numbered paragraphs, simply worded instructions for firing the device). 
Service Life Expiration Date (date to be inserted by manufacturer) 
(Month and year manufactured) (Lot No. __) Manufactured by (Name and 
address of manufacturer) U.S. Coast Guard Approval No. __.

    (b) Marking of expiration date. The expiration date must be not more 
than 42 months from the date of manufacture.
    (c) Other marking. (1) On each hand-held rocket propelled parachute 
red flare distress signal there shall be die-stamped in figures not less 
than 3 mm (\1/8\ in.) high, on the signal, numbers indicating the month 
and year of manufacture, thus: ``6-54'' indicating June, 1954.
    (2) The pyrotechnic candle shall be legibly marked with the month 
and year of manufacture.
    (3) In addition to any other marking place on the smallest packing 
carton or box containing signals, each carton or

[[Page 81]]

box shall be plainly and permanently marked to show the service life 
expiration date, date of manufacture, and lot number.
    (4) The largest carton or box in which the manufacturer ships 
signals must be marked with the following or equivalent words: ``Keep 
under cover in a dry place.''

    Note: Compliance with the labeling requirements of this section does 
not relieve the manufacturer of the responsibility of complying with the 
label requirements of 15 U.S.C. 1263, the Federal Hazardous Substances 
Act.



Sec.  160.036-6  Container.

    (a) General. The container for storing the signals on lifeboats and 
liferafts is not required to be of a special design or be approved by 
the Coast Guard. The container must meet the requirements in Subpart 
160.021 (Sec.  160.021-6) except that the wording on the container must 
be:

Sec.  160.037-2  Type.

    (a) Hand orange smoke distress signals specified by this subpart 
shall be one type which shall consist essentially of a wooden handle to 
which is attached a tubular casing having a sealing plug at the handle 
end, the casing being filled with a smoke producing composition and fuse 
with button of ignition material at the top, and a removable cap having 
a friction striking material on its top which may be exposed for use by 
pulling a tear strip. The signal is ignited by scraping the friction 
striker on top of the cap against the igniter button on top of the body 
of the signal. Alternate arrangements which conform to the performance 
requirements of this specification will be given special consideration.
    (b) [Reserved]



Sec.  160.037-3  Materials, workmanship, construction, and performance
requirements.

    (a) Materials. The materials shall conform strictly to the 
specifications and drawings submitted by the manufacturer and approved 
by the Commandant. The color of the tube shall be orange. The 
combustible materials shall be of such nature as will not deteriorate 
during long storage, nor when subjected to frigid or tropical climates, 
or both.

[[Page 82]]

    (b) Workmanship. Hand orange smoke distress signals shall be of 
first class workmanship and shall be free from imperfections of 
manufacture affecting their appearance or that may affect their 
serviceability. Moisture proof coatings shall be applied uniformly and 
shall be free from pinholes or other visible defects which would impair 
their usefulness.
    (c) Construction. The casing shall be fitted and secured to the 
handle with not less than a 25 mm (1 in.) overlap and shall be attached 
to the handle in such a manner that failure of the joint will not occur 
during tests, ignition, or operation. The plug shall be securely affixed 
in the casing to separate the smoke composition from the wooden handle. 
The smoke composition shall be thoroughly mixed and be uniformly 
compressed throughout to preclude variations of density which may 
adversely affect uniformity of its smoke emitting characteristics. The 
cap shall have a lap fit of not less than 25 mm (1 in.) over the end of 
the casing and smoke composition to entirely and securely protect the 
exposed surface of the igniter button and end of smoke composition and 
casing, and shall have an inner shoulder so constructed that it is 
mechanically impossible for the inner surface of the cap to come in 
contact with the igniter button. The cap shall be securely attached to 
the casing in such manner as to preclude its accidental detachment. The 
cap shall be provided on its top with a friction striking material which 
shall, by a pull of the tear strip, be entirely exposed for striking the 
friction igniter button. The igniter button shall be non-water soluble 
or be protected from moisture by a coating of some waterproof substance, 
and shall be raised or exposed in such manner as to provide positive 
ignition by the friction striker. The igniter button shall be firmly 
secured in or on the top of the smoke composition; the arrangement shall 
be such that the ignition will be transmitted to the smoke producing 
composition. The assembled signal, consisting of tear strip, cap, 
casing, and handle, shall be sealed and treated to protect the signal 
from deterioration by moisture. The protective waterproof coating shall 
be applied so none adheres to the friction striking surface. Special 
consideration will be given to alternate waterproofing of the signal by 
means of a water-resistant coating on the signal plus packaging in a 
sealed plastic waterproof bag satisfactory to the Commandant.
    (d) Performance. Signals shall meet all the inspection and test 
requirements contained in Sec.  160.037-4.



Sec.  160.037-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
100 signals from which samples must be taken for testing for approval 
under Sec.  160.037-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.
    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 30,000 signals. Lots must 
be numbered serially by the manufacturer. A new lot must be started 
with:
    (i) Any change in construction details,
    (ii) Any change in sources of raw materials, or
    (iii) The start of production on a new production line or on a 
previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into

[[Page 83]]

construction of the signals and inspection of the finished signals, to 
determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.
    (3) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this Chapter must perform or supervise the inspections and tests under 
paragraph (b)(2) of this section at least 4 times a year, unless the 
number of lots produced in a year is less than four. The inspections and 
tests must occur at least once during each quarterly period, unless no 
lots are produced during this period. If less than four lots are 
produced, the laboratory must perform or supervise the inspection and 
testing of each lot. In addition, the laboratory must perform or 
supervise the technical tests in paragraph (d) of this section at least 
once for every ten lots of signals produced, except that the number of 
technical tests must be at least one but not more than four per year. If 
a lot of signals tested by the independent laboratory is rejected, the 
laboratory must perform or supervise the inspections and tests of the 
reworked lot and the next lot of signals produced. The tests of each 
reworked lot and the next lot produced must not be counted for the 
purpose of meeting the requirement for the annual number of inspections 
and tests performed or supervised by the independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.037-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defeats (Table 
160.037-4(c)(2)) is assigned a score (failure percent) in accordance 
with that table. In the case of multiple defects, only the score having 
the highest numerical value is assigned to that signal. If the sum of 
all the failure percents (cumulative failure percent) for the number of 
units in the sample is less than or equal to the accept criterion, the 
lot is accepted. If the sum is equal to or more than the reject 
criterion the lot is rejected. If the cumulative failure percent falls 
between the accept and reject criteria, another sample is selected from 
the production lot and the operational tests are repeated. The 
cumulative failure percent of each sample tested is added to that of the 
previous samples to obtain the cumulative failure percent for all the 
signals tested (cumulative sample size). Additional samples are tested 
and the tests repeated until either the accept or reject criterion for 
the cumulative sample size is met. If any signal in the sample explodes 
when fired, or ignites in a way that could burn or otherwise injure the 
person firing it, the lot is rejected without further testing. (This 
procedure is diagrammed in figure 160.037-4(c)).
    (2) Test procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water resistance. Immerse 
specimen horizontally with uppermost portion of the signal approximately 
25 mm (1 in.) below the surface of the water for a period of 24 hours. 
If the signal is protected by alternate waterproofing consisting of a 
water-resistant coating on the signal plus packaging in a sealed plastic 
waterproof bag, the 24-hour water immersion conditioning will be 
conducted while the signal is in the sealed plastic waterproof bag and 
will be followed by an additional immersion of the bare signal (i.e., 
after removal from the bag) 25 mm (1 in.) below the surface of the water 
for a period of 10 minutes.
    (ii) Waterproofing of igniter button. Remove the cap from the test 
specimen. Place head of specimen without cap about 25 mm (1 in.) under 
the surface of water for approximately 5 minutes. Remove specimen from 
the water and wipe dry.
    (iii) Smoke emitting time. Ignite specimen according to directions 
printed on the signal. The smoke emitting time of a specimen shall be 
obtained by stop watch measurements from the time of distinct, sustained 
smoke emission until it ceases. The watch shall be

[[Page 84]]

stopped during periods of flame emission. The smoke emitting time for a 
specimen shall be not less than 50 seconds.
    (iv) Ignition and smoke emitting characteristics. Test specimens 
shall ignite and emit smoke properly when the directions on the signal 
are followed. Test specimens shall not ignite explosively in a manner 
that might be dangerous to the user or persons close by. The plug 
separating the smoke producing composition from the handle shall in no 
case allow flame or hot gases to pass through it or between it and the 
casing in such manner as might burn the hand while holding the signal by 
the handle.

    (d) Technical tests. Three signals must be subjected to each of the 
following tests. Two of the three signals must pass each test in order 
for the lot of signals to be accepted.
    (1) Underwater smoke emission. Condition each sample in accordance 
with

[[Page 86]]

paragraph (c)(2)(i) of this section. Ignite specimen and let it burn 
about 15 seconds in air. Submerge the burning signal in water in a 
vertical position with head down. Obtain underwater smoke emission time 
by stop watch measurements from time of submersion until smoke emission 
ceases. The test specimen shall burn underwater not less than 10 seconds 
when subjected to this test.
    (2) Bending strength. Place the specimen on supports 15 cm (6 in.) 
apart. Attach a weight of 35 kg (77 lb.) to a length of wire. Hang the 
weight from the supported signal by looping the wire around the signal 
approximately equidistant from the two points of support. Let the weight 
hang approximately 5 minutes. The test specimen shall not deflect more 
than 7 mm (\1/4\ in.), nor shall the joint between the casing and the 
handle fail when subjected to this test.
    (3) Tensile strength. Place the specimen in a chuck firmly holding 
it about 13 mm (\1/2\ in.) below the cap. Attach a weight of 35 kg (77 
lb.) to a length of wire. Hang the weight from the supported signal by 
looping the wire through a hole bored perpendicular to and through the 
axis of the handle. Let the weight hang approximately 5 minutes. The 
test specimen shall not show noticeable distortion, nor shall the joint 
between the casing and handle fail, when subjected to this test.
    (4) Elevated temperature, humidity and storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for 10 days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during the 72-hour conditioning period. 
(Total of 24 hours on and 48 hours off.) The signal shall not ignite or 
decompose during this conditioning. The signal shall ignite and operate 
satisfactorily following this conditioning.
    (5) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signal shall not 
ignite or undergo marked decomposition.
    (6) Susceptibility to explosion. Remove smoke composition from 
signal and punch a small hole in the composition. Insert a No. 6 
commercial blasting cap. Ignite the cap. The test specimen shall not 
explode or ignite.
    (7) Color of smoke. Ignite specimen in the open air in daytime 
according to the directions printed on the signal, and determine the 
smoke color by direct visual comparison of the unshadowed portions of 
the smoke with a color chart held so as to receive the same daylight 
illumination as the unshadowed portions of the smoke. The color of the 
smoke must be orange as defined by Sections 13 and 14 of the ``Color 
Names Dictionary'' (colors 34-39 and 48-54).
    (8) Volume and density of smoke. The test specimen shall show less 
than 70 percent transmission for not less than 30 seconds when measured 
with apparatus having a light path of 19 cm (7\1/2\ in.), an optical 
system aperture of + 3.7 degrees, and an entrance air flow of 18.4m\3\ 
per minute (650 cu. ft. per minute), such apparatus to be as described 
in National Bureau of Standards Report No. 4792.



Sec.  160.037-5  Labeling and marking.

    (a) Labeling. Each hand orange smoke distress signal shall bear a 
label securely affixed thereto, showing in clear, indelible black 
lettering on an orange background, the following wording and

Sec.  160.040-5  Approval and production tests.

    (a) Approval tests. An independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter must perform or supervise 
the performance tests in paragraph (c) of this section.
    (b) Production inspections and tests. Production inspections and 
tests must be conducted under the procedures in Sec.  159.007 of this 
chapter. Each appliance or lot of rockets which fails the inspections 
and tests must not be represented

[[Page 90]]

as meeting this subpart or as being approved by the Coast Guard.
    (1) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include the inspection of appliances 
during production as well as inspection of finished appliances, to 
determine that the appliances are being produced in accordance with the 
approved plans. The performance tests in paragraph (c) of this section 
must be performed by the manufacturer.
    (2) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this chapter must inspect and test appliances and rockets at least once 
each year. The inspection must determine that the appliances and rockets 
are being produced in accordance with the appropriate plans. The tests 
must be in accordance with paragraph (c) of this section.
    (c) Performance tests--(1) Appliances. Each appliance shall be 
tested by firing three rounds. These rounds may be regular rockets or 
buoyant type rockets carrying regular service lines, as provided in 
paragraph (c)(2) of this paragraph or may be dummy projectiles, of the 
same size and weight as the regular rocket projectile, expelled into an 
earthen bank or other resisting medium from a reasonable distance. At 
least one of the rounds shall be fired using a primer-ejector cartridge 
loaded with a charge double the normal charge; the other rounds may be 
fired using regular primer-ejector cartridges. After the firing tests 
have been completed, each appliance shall be fired twice using the 
regular primer-ejector cartridges only, for the purposes of 
demonstrating that the appliance is still in operating condition. The 
entire assembly of the appliance shall then be examined. Results of the 
test firing and the physical examination shall show none of the 
following: Failure to eject cartridge, failure to close breech, trigger 
malfunction, safety lock failure to function, breech catch malfunction, 
broken spring, broken handgrips, cracked barrel or discharge chamber, 
firing pin or plunger broken, distorted or excessively worn or loose 
breech. A single misfire is acceptable if a second cartridge fires on 
repeated test. Misfire of both shall be cause for rejection of the 
appliance. More than one loose screw shall be cause for rejection. If an 
appliance exhibits a single loose screw, it may be retightened.
    (2) Rockets. The rocket shall utilize a solid fuel propellant which 
shall function in accordance with all applicable requirements of MIL-R-
23139. The use of black powder for the rocket motor is not acceptable. 
The ignition of the rocket motor shall occur at such a distance from the 
appliance so as not to spew flame, hot gaseous exhaust, or hot particles 
of propellant in such a manner as to create a hazard to personnel or the 
vessel. The rocket shall have a service line carrier assembly 
permanently attached and made of material, or suitably protected, to 
withstand the heat from the rocket motor's exhaust. From each 200 
rockets manufactured, not less than three must be selected to be tested 
by firing with service line attached. The rockets selected will, over a 
period of time, include representative samples of both the regular and 
buoyant type rockets, except that the approval test must include both 
types. The line shall be carried, under conditions of reasonably still 
atmosphere, a minimum of 230 m (750 ft.), without breaking or fouling 
the line, and the rocket shall alight not more than 15 m (50 ft.) from 
either side of the target line. In no case shall a test rocket be fired 
without a line attached. After a buoyant type rocket is fired, it shall 
demonstrate its ability to float in water for not less than 2 hours. 
Failure to meet any of the test requirements, nose cone cracks, rupture 
in flight, erratic flight, or unusual burning rate, shall be cause for 
rejection of rockets produced until suitable correction has been made. 
If rockets selected from this lot are used for the tests required in 
paragraph (c)(1) of this section this may be accepted as meeting the 
requirements of this paragraph.
    (3) Primer-ejector cartridges. Inasmuch as primer-ejector cartridges 
are used for the tests required by paragraphs (c) (1) and (2) of this 
paragraph, additional tests of primer-ejector cartridges will be made 
only when deemed advisable by the independent laboratory. Misfiring or 
failure of any kind shall be

[[Page 91]]

cause for rejection of cartridges produced until suitable correction has 
been made.



Sec.  160.040-6  Marking and labeling.

    (a) The appliance shall be permanently and legibly marked by die-
stamping or raised letters with the model designation of the appliance,

Sec.  160.047-4  Construction.

    (a) General. This specification covers buoyant vests which 
essentially consist of a vest-cut envelope containing compartments in 
which are enclosed pads of buoyant material arranged and distributed so 
as to provide the proper flotation characteristics and buoyancy required 
to hold the wearer in an upright backward position with head and face 
out of water. The buoyant vests are also fitted with tapes, webbing, and 
hardware to provide for proper adjustment and close and comfortable fit 
to the bodies of various size wearers.
    (b) Envelope. The envelope or cover shall be cut to the pattern 
shown on Dwg. No. 160.047-1, Sheet 1, for adult size, and Sheets 2 and 3 
for child sizes, and sewed with seams and stitching as shown on the 
drawing. Three compartments shall be formed to hold the buoyant pad 
inserts, two front compartments and one back compartment, and 
reinforcing strips of the same material as the cover shall be stitched 
to the inside of the front compartments in way of the strap attachments 
as shown by the drawings. As alternate construction, the front and/or 
back cover panels may be made in two pieces, provided that the two 
pieces are joined by a double stitched seam from the top center of the 
neck hole to the top of the vest as shown in Section J-J of the 
drawings.
    (c) Pad inserts--(1) Forming and sealing. The buoyant pad inserts 
shall each be formed from two pieces of film cut to the patterns shown 
by Dwg. No. 160.047-1, Sheet 4, which shall be heat-sealed tight. The 
heat-sealed pad seams shall show an adhesion of not less than 8 pounds 
when 1 inch strips cut across and perpendicular to the seams are pulled 
apart at a rate of separation of the clamping jaws of the test machine 
of 12 inches per minute.
    (2) Kapok-filled pads for Models AK-1, CKM-1, and CKS-1. The buoyant 
pad inserts for Models AK-1, CKM-1, and CKS-1 buoyant vests shall be

to measure the actual buoyancy provided by the pads, proceed as follows:
    (i) Weigh the empty wire basket under water.
    (ii) Place the pads inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water 
for 24 hours. The tank shall be locked or sealed during this 24-hour 
submergence period. It is important that after the pads have once been 
submerged they shall remain submerged for the duration of the test, and 
at no time during the course of the test shall they be removed from the 
tank or otherwise exposed to air.
    (iii) After the 24-hour submergence period unlock or unseal the tank 
and weigh the weighted wire basket with the pads inside while both are 
still under water.
    (iv) The buoyancy is computed as (i) minus (iii).

Sec.  160.048-4  Construction and workmanship.

    (a) General. This specification covers buoyant cushions of the box 
type filled with kapok or fibrous glass contained in heat-sealed vinyl 
film pad covers which are inserted in an outer cover fitted with grab 
straps. The primary purpose of such cushions is to provide buoyancy to 
aid a person in keeping afloat in the water. No hooks, snaps, or other 
means shall be included which might facilitate fastening the cushion to 
a boat. Buoyant cushions shall be of such size and volume as to provide 
not less than 20 pounds buoyancy when tested in the manner described in 
Sec.  160.048-5(e), but no cushion providing less than 225 square inches 
of top surface area or measuring less than 2 inches or more than 3 
inches in thickness will be acceptable.
    (b) Cover. One piece of material each for the top and bottom shall 
be

[[Page 105]]

stitched together to form the cover except that piecing of the cover 
material will be allowed provided it is for decorative purposes only. 
Gusset or boxing materials shall be of not more than two pieces. If more 
than one piece of material is used for the top, bottom, boxing or 
gusset, they shall be attached by a double row of stitching of the type 
shown in Federal Standard No. 751, for seam types SSw-2 or LS(b)-2. The 
top and bottom may be of any of the materials permitted for the cover, 
but the boxing or gusset shall be a cotton fabric as specified by Sec.  
160.048-3(c)(1) or other equivalent material of a porous nature. 
Nonporous materials will not be permitted for the boxing or gusset, but 
coated upholstery cloth specified by Sec.  160.048-3(d)(2), perforated 
to permit adequate draining and drying will be acceptable.
    (c) Buoyant material. Buoyant cushions shall be filled with the 
minimum amounts of kapok or fibrous glass determined as follows:
    (1) Rectangular buoyant cushions 2 inches thick shall be filled with 
the amounts of kapok or fibrous glass indicated for the various widths 
and lengths of such cushions by Table 160.048-4(c)(1)(i) or 160.048-
4(c)(1)(ii), as applicable. Trapezoidal buoyant cushions 2 inches thick 
shall be filled with the amounts of kapok or fibrous glass indicated for 
the various widths and lengths of rectangular buoyant cushions by Table 
160.048-4(c)(1)(i) or 160.048-4(c)(1)(ii) as applicable, on the basis 
that the length of a trapezoidal cushion shall be considered as its 
average length in each case.

[[Page 107]]

    (2) All buoyant cushions more than 2 inches thick, and all buoyant 
cushions 2 inches thick which are of shapes different from those covered 
by paragraph (c)(1) of this section, shall be filled with kapok or 
fibrous glass as determined in the following formulas:

Amount of kapok (ounces) = A x t / 22.5 (1)

Amount of fibrous glass (ounces) = A x t / 12.5 (2)

Where:

A = Top surface area of cushion in square inches as determined from 
          measurements taken along finished edges.
t = Thickness of boxing or gusset of finished cushion in inches.

    (d) Pad covers for buoyant material. Before being inserted in the 
outer cover the buoyant material shall be placed in waterproof vinyl 
film pad covers which shall be heat-sealed tight. The heat-sealed pad 
seams shall show an adhesion of not less than 8 pounds when one inch 
strips cut across and perpendicular to the seams are pulled apart at a 
rate of separation of the clamping jaws of the test machine of 12 inches 
per minute. Each cushion shall contain not less than four pads and all 
pads in a cushion shall contain approximately equal portions of the 
total amount of buoyant material in the cushion. The buoyant material 
may be inserted directly into the vinyl film pad covers, or may first be 
packed in bags made of print cloth or other suitable material and then 
inserted into the vinyl film pad covers. The pads shall be of such size 
as to adequately fill the outer cover, and prior to sealing, the pads 
shall be evacuated of air sufficiently that when sat on the pads will 
not ``balloon'' excessively because of the pressure in the pad covers. 
For 15 x 15 x 2 cushions the four vinyl 
film pad covers shall each be cut approximately 12 wide x 
12 long or approximately 8 wide x 18 
long shall have a sealed area of approximately 125 square inches; shall 
contain not less than 5 ounces of kapok or 9 ounces of fibrous glass 
each; and the volume displacement of the individual heat-sealed pad 
inserts shall be 5\1/2\ pounds each, plus or minus \1/2\ pound, when 
tested in accordance with the method set forth in Sec.  160.048-5(e)(1), 
except that the pad covers shall not be slit open, and the period of 
submergence shall be only long enough to determine the displacement of 
the pads.
    (e) Grab straps. Grab straps shall be attached as shown on Dwg. No. 
160.048-1 and shall finish 20 inches long and 1 inch wide at opposite 
ends. The grab straps, if formed from cover material shall be folded and 
stitched together so as to produce a double thickness with raw edges 
turned under. Other means will be given special consideration.
    (f) Seams and stitching. Seams shall be constructed with not less 
than a \3/8\ inch border between the seam and the edge of the cover 
materials. All stitching shall be a lock stitch, 7 to 9 stitches per 
inch, except as follows: Chain stitching 6 to 8 stitches per inch, with 
20/4 thread on top and 40/3 thread on the bottom, will be acceptable in 
constructing straps.
    (g) Workmanship. All cushions shall be of first class workmanship 
and shall be free from defects materially affecting their appearance or 
serviceability. Cushions classified as ``seconds'' or ``irregular'' will 
not be acceptable under this specification.

---------------------------------------------------------------------------

    (a) General. Manufacturers of listed and labeled buoyant cushions 
shall maintain quality control of the materials used, manufacturing 
methods and the finished product so as to meet the applicable 
requirements, and shall make sufficient inspections and tests of 
representative samples and components produced to maintain the quality 
of the finished product. Records of tests conducted by the manufacturer 
and records of materials, including affidavits by suppliers that 
applicable requirements are met, entering into construction shall be 
made available to the recognized laboratory inspector or the Coast Guard 
inspector, or both, for review upon request. Any examinations, 
inspections and test which are required by the recognized laboratory for 
listed and labeled devices produced

[[Page 108]]

will be conducted by the laboratory inspector at the place of 
manufacture or other location at the option of the laboratory.
    (b) Lot size and sampling. (1) A lot shall consist of not more than 
1,000 buoyant cushions. A new lot shall be started with any change or 
modification in materials used or manufacturing methods employed. When a 
lot of buoyant cushions is ready for inspection, the manufacturer shall 
notify the recognized laboratory so that they may, at their discretion, 
assign an inspector to the plant for the purpose of making any tests and 
inspections deemed necessary. From each lot of buoyant cushions, the 
manufacturer or the recognized laboratory or U.S. Coast Guard inspector, 
when assigned, shall select samples in accordance with Table 160.048-
5(b)(1) to be tested for buoyancy in accordance with paragraph (e) of 
this section.

    (2) For a lot next succeeding one from which any sample cushion 
failed the buoyancy test, the sample shall consist of not less than 10 
specimen cushions to be tested for buoyancy in accordance with paragraph 
(e) of this section.
    (c) Additional tests. Unannounced examinations, tests and 
inspections of samples obtained either directly from the manufacturer or 
through commercial channels may be made to determine the suitability of 
a product for listing and labeling, or to determine conformance of a 
labeled product to the applicable requirements. These may be conducted 
by the recognized laboratory or the Coast Guard.
    (d) Test facilities. The laboratory inspector, or the Coast Guard 
inspector, or both, shall be admitted to any place in the factory where 
work is being done on listed and labeled products, and either or both 
inspectors may take samples of parts or materials entering into 
construction of final assemblies, for further examinations, inspections, 
or tests. The manufacturer shall provide a suitable place and the 
apparatus necessary for the performance of the tests which are done at 
the place of manufacture.
    (e) Buoyancy--(1) Buoyancy test method. Remove the buoyant pad 
inserts from the cushion and cut three slits in the vinyl film, each not 
less than 6 inches in length on both sides of each pad. Securely attach 
the spring scale in a position directly over the test tank. Suspend the 
weighted wire basket from the scale in such a manner that the basket is 
weighed while it is completely under water. In order to measure the 
actual buoyancy provided by the pads, the underwater weight of the empty 
basket should exceed the buoyancy of the pads. To obtain the buoyancy of 
the pads, proceed as follows:
    (i) Weigh the empty wire basket under water.
    (ii) Place the pads inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water 
for 24 hours. The tank shall be locked or sealed during this 24-hour 
submergence period. It is important that after the pads have once been 
submerged that they shall remain submerged for the duration of the test, 
and at no time during the course of the test shall they be removed from 
the tank or otherwise exposed to air.
    (iii) After the 24-hour submergence period unlock or unseal the tank 
and weigh the weighted wire basket with the pads inside while both are 
still under water.
    (iv) The buoyancy is computed as (i) minus (iii).
    (2) Buoyancy required. The buoyant pads from the cushion shall 
provide not less than 20 pounds total buoyancy.

all-purpose vinyl adhesive such as or equivalent to U.S. Rubber No. M-
6256 or Minnesota Mining No. EC-870 and No. EC-1070;
    (ii) Three layers or less that may be cemented; and
    (iii) Staggered butts and seams of adjacent layers.
    (d) Grab Straps. Grab straps shall be attached as shown on Dwg. No. 
160,049-1 and shall finish 20 inches long and 1 inch wide at opposite 
ends. The grab straps, if formed from cover material shall be folded and 
stitched together so as to produce a double thickness with raw edges 
turned under. Other means will be given special consideration.
    (e) Seams and stitching. Seams shall be constructed with not less 
than a \3/8\-inch border between the seam and the edge of the cover 
materials. All stitching shall be a lock stitch, 7 to 9 stitches per 
inch, except as follows: Chain stitching 6 to 8 stitches per inch with 
20/4 thread on top and 40/3 thread on the bottom, will be acceptable in 
constructing grab straps.

    (c) Additional tests. Unannounced examinations, tests and 
inspections of samples obtained either directly from the manufacturer or 
through commercial channels may be made to determine the suitability of 
a product for listing and labeling, or to determine conformance of a 
labeled product to the applicable requirements. These may be conducted 
by the recognized laboratory or the U.S. Coast Guard.
    (d) Test facilities. The laboratory inspector, or the Coast Guard 
inspector, or both, shall be admitted to any place in the factory where 
work is being done on listed and labeled products, and either or both 
inspectors may take samples of parts or materials entering into 
construction of final assemblies, for further examinations, inspections, 
or tests. The manufacturer shall provide a suitable place and the 
apparatus necessary for the performance of the tests which are done at 
the place of manufacture.
    (e) Buoyancy--(1) Buoyancy test method. Securely attach the spring 
scale in a position directly over the test tank. Suspend the weighted 
wire basket from the scale in such a manner that the basket is weighed 
while it is completely under water. In order to measure the actual 
buoyancy provided by the cushion, the underwater weight of the empty 
basket should exceed the buoyancy of the cushion. To obtain the buoyancy 
of the cushion, proceed as follows:
    (i) Weigh the empty wire basket under water.
    (ii) Place the cushion inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water 
for 24 hours. The tank shall be locked or sealed during this 24-hour 
submergence period. It is important that after the cushion has once been 
submerged that it shall remain submerged for the duration of the test, 
and at no time during the course of the test shall it be removed from 
the tank or otherwise exposed to air.
    (iii) After the 24-hour submergence period unlock or unseal the tank 
and weigh the weighted wire basket with the cushion inside while both 
are still under water.
    (iv) The buoyancy is computed as (i) minus (iii).
    (2) Buoyancy required. Each cushion shall provide not less than 20 
pounds buoyancy.

Sec.  160.050-4  Construction and workmanship.

    (a) General. This specification covers ring life buoys which provide 
buoyancy to aid in keeping persons afloat in the water. Each buoy 
consists of a body constructed in the shape of an annular ring, with an 
approximately elliptical body cross section and which is fitted with a 
grab line around the outside periphery. The outside and inside diameters 
of the ring and the length and width of the cross section of the body 
shall be uniform throughout.
    (b) Body. The body shall be made in either one or two pieces. If of 
two pieces, the pieces shall be equal in size and shall be adhesive 
bonded along a center line through an axis passing through the flat area 
dimension of the body. The adhesive shall be a liquid cold setting, 
polymerizable, nonsolvent, containing material of the 
phenolepichlorhydrin type or equivalent having good strength retention 
under outdoor weathering conditions.
    (c) Grab line. The finished length of the grab line shall be four 
times the outside diameter of the buoy. The ends of the grab line shall 
be securely and neatly spliced together, or shall be hand whipped with a 
needle and both ends securely and smoothly seized together. The grab 
line shall encircle the buoy and shall be held in place by the beckets. 
The spliced or seized ends of the grab line shall be placed in the 
center of the width of one of the beckets.
    (d) Beckets. Each ring buoy shall be fitted with four beckets 
located at equidistant points about the body of the buoy. The beckets 
shall be passed around the body of the buoy with the free ends to the 
outside, and shall be securely cemented to the buoy with a suitable 
waterproof adhesive which is compatible with the unicellular plastic 
used in the buoy body. The ends of the beckets shall be turned under at 
least 1 inch, one end to go around the grab line, and the other to be 
laid flat against the first end. The beckets shall then be stitched to 
the grab line with not less than five hand stitches made with two parts 
of thread or machined stitched with not less than three stitches per 
inch. Alternate methods for rigging beckets and grab line will be given 
special consideration.
    (e) Weight. The weight of the completely assembled buoy shall be not 
less than 2.5 pounds and not more than 4.25 pounds for the 20-inch size, 
not less than 3.0 pounds and not more than 5.5 pounds for the 24-inch 
size, and not less than 5.0 and not more than 7.5 pounds for the 30-inch 
size.
    (f) Workmanship. Ring life buoys shall be of first class workmanship 
and free from any defects materially affecting their appearance or 
serviceability.

Sec.  160.050-5  Sampling, tests, and inspection.

    (a) General. Production tests and inspections must be conducted in 
accordance with this section, subpart 159.007 of this chapter, and if 
conducted by an independent laboratory, the independent laboratory's 
procedures for production inspections and tests as accepted by the 
Commandant. The Commandant may prescribe additional production tests and 
inspections necessary to maintain quality control and to monitor 
compliance with the requirements of this subchapter.
    (b) Oversight. In addition to responsibilities set out in part 159 
of this chapter and the accepted laboratory procedures for production 
inspections and tests, each manufacturer of a ring life buoy and each 
laboratory inspector shall comply with the following, as applicable:
    (1) Manufacturer. Each manufacturer must--
    (i) Perform all tests and examinations necessary to show compliance 
with this subpart and the subpart under which the ring life buoy is 
approved on each lot before any inspector's tests and inspection of the 
lot;
    (ii) Follow established procedures for maintaining quality control 
of the materials used, manufacturing operations, and the finished 
product; and
    (iii) Allow an inspector to take samples of completed units or of 
component materials for tests required by this subpart and for tests 
relating to the safety of the design.
    (iv) Meet 33 CFR 181.701 through 33 CFR 181.705 which requires an 
instruction pamphlet for each device that is sold or offered for sale 
for use on recreational boats, and must make the pamphlet accessible 
prior to purchase.
    (2) Laboratory. An inspector from the accepted laboratory shall 
oversee production in accordance with the laboratory's procedures for 
production inspections and tests accepted by the Commandant. During 
production oversight, the inspector shall not perform or supervise any 
production test or inspection unless--
    (i) The manufacturer has a valid approval certificate; and
    (ii) The inspector has first observed the manufacturer's production 
methods and any revisions to those methods.
    (3) At least quarterly, the inspector shall check the manufacturer's 
compliance with the company's quality control procedures, examine the 
manufacturer's required records, and observe the manufacturer perform 
each of the required production tests.
    (c) Test facilities. The manufacturer shall provide a suitable place 
and apparatus for conducting the tests and inspections necessary to 
determine compliance of ring life buoys with this subpart. The 
manufacturer shall provide means to secure any test that is not 
continuously observed, such as the 48 hour buoyancy test. The 
manufacturer must have the calibration of all test equipment checked in 
accordance with the test equipment manufacturer's recommendation and 
interval but not less than at least once every year.
    (d) Lots. A lot may not consist of more than 1000 life buoys. A lot 
number must be assigned to each group of life buoys produced. Lots must 
be numbered serially. A new lot must be started whenever any change in 
materials or a revision to a production method is made, and whenever any 
substantial discontinuity in the production process occurs. The lot 
number assigned, along with the approval number, must enable the ring 
life buoy manufacturer to determine the supplier's identifying 
information for the component lot.
    (e) Samples. (1) From each lot of ring life buoys, manufacturers 
shall randomly select a number of samples from completed units at least 
equal to the applicable number required by table 160.050-5(e) for 
buoyancy testing. Additional samples must be selected for any tests, 
examinations, and inspections required by the laboratory's production 
inspections and tests procedures.

    (2) For a lot next succeeding one from which any sample ring life 
buoy failed the buoyancy or strength test, the sample shall consist of 
not less than ten specimen ring life buoys to be tested for buoyancy in 
accordance with paragraph (f) of this section.
    (f) Tests--(1) Strength test. The buoy body shall be suspended by a 
2-inch-wide strap. A similar strap shall be passed around the opposite 
side of the buoy and a 200-pound weight suspended by it from the buoy. 
After 30 minutes, the buoy body shall be examined, and there shall be no 
breaks, cracks or permanent deformation.
    (2) Resistance to damage test. The buoy body shall be dropped three 
times from a height of 6 feet onto concrete, and there shall be no 
breaks or cracks in the body.
    (3) Buoyancy test. To obtain the buoyancy of the buoy, proceed as 
follows:
    (i) Weigh iron or other weight under water. The weight shall be more 
than sufficient to submerge the buoy.
    (ii) Attach the iron or other weight to the buoy and submerge with 
the top of the buoy at least 2 inches below the surface for 48 hours.
    (iii) After the 48-hour submergence period, weigh the buoy with the 
weight attached while both are still under water.
    (iv) The buoyancy is computed as paragraph (f)(3)(i) minus paragraph 
(f)(3)(iii) of this section.
    (4) Buoyancy required. The buoys shall provide a buoyancy of not 
less than 16.5 pounds for the 20-and 24-inch sizes, and not less than 32 
pounds for the 30-inch size.
    (g) Lot inspection. On each lot, the laboratory inspector shall 
perform a final lot inspection to be satisfied that the ring life buoys 
meet this subpart. Each lot must demonstrate--
    (1) First quality workmanship;
    (2) That the general arrangement and attachment of all components 
are as specified in the approved plans and specifications; and
    (3) Compliance with the marking requirements in the applicable 
approval subpart.
    (h) Lot acceptance. When the independent laboratory has determined 
that the ring life buoys in the lot are of a type officially approved in 
the name of the company, and that such ring life buoys meet the 
requirements of this subpart, they shall be plainly marked in waterproof 
ink with the independent laboratory's name or identifying mark.
    (i) Lot rejection. Each nonconforming unit must be rejected. If 
three or more nonconforming units are rejected for the same kind of 
defect, lot inspection must be discontinued and the lot rejected. The 
inspector must discontinue lot inspection and reject the lot if 
examination of individual units or the records for the lot shows 
noncompliance with either this subchapter or the laboratory's or the 
manufacturer's quality control procedures. A rejected unit or lot may be 
resubmitted for testing and inspection if the manufacturer first removes 
and destroys each defective unit or, if authorized by the laboratory, 
reworks the unit or lot to correct the defect. A rejected lot or 
rejected unit may not be sold or offered for sale under the 
representation that it meets this subpart or that it is Coast Guard-
approved.

    (5) The manufacturer shall test--
    (i) At least one vest from each lot for buoyancy in accordance with 
procedures contained in paragraph (e) of this section; and
    (ii) At least one vest in each 10 lots for strength of the body 
strap assembly in accordance with the procedures contained in paragraph 
(f) of this section.
    (6) If a vest fails the buoyancy test, the sample from the next 
succeeding lot must consist of 10 specimen vests or more to be tested 
for buoyancy in accordance with paragraph (e) of this section.
    (7) The manufacturer shall keep on file and make available to the 
laboratory inspector and Coast Guard inspector the records of 
inspections and tests, together with affidavits concerning the material.
    (c) Additional compliance tests. An inspector from the recognized 
laboratory or Coast Guard may conduct an examination, test and 
inspection of a buoyant device that is obtained from the manufacturer or 
through commercial channels to determine the suitability of the device 
for listing and labeling or to determine its conformance to applicable 
requirements.
    (d) Test facilities. The manufacturer shall admit the laboratory 
inspector and the Coast Guard inspector to any part of the premises at 
the place of manufacture of a listed and labeled device to--
    (1) Examine, inspect, or test a sample of a part or a material that 
is included in the construction of the device; and
    (2) Conduct any necessary examination, inspection, or test in a 
suitable place and with appropriate apparatus provided by the 
manufacturer.
    (e) Buoyancy--(1) Buoyancy test method. Remove the buoyant inserts 
from the vests. Securely attach the spring scale in a position directly 
over the test tank. Suspend the weighted wire basket from the scale in 
such a manner

[[Page 124]]

that the basket can be weighed while it is completely under water. In 
order to measure the actual buoyancy provided by the inserts, the 
underwater weight of the empty basket should exceed the buoyancy of the 
inserts. To obtain the buoyancy of the inserts, proceed as follows:
    (i) Weigh the empty wire basket under water.
    (ii) Place the inserts inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water. 
Allow the inserts to remain submerged for 24 hours. The tank shall be 
locked or sealed during this 24-hour submergence period. It is important 
that after the inserts have once been submerged they shall remain 
submerged for the duration of the test, and at no time during the course 
of the test shall they be removed from the tank or otherwise exposed to 
air.
    (iii) After the 24-hour submergence period, unlock or unseal the 
tank and weigh the wire basket with the inserts inside while both are 
still under water.
    (iv) The buoyancy is computed as paragraph (e)(1)(i) of this section 
minus paragraph (e)(i)(iii) of this section.
    (2) Buoyancy required. The buoyant inserts from adult size buoyant 
vests shall provide not less than 15\1/2\ pounds buoyancy in fresh 
water; the inserts from child medium size vests shall provide not less 
than 11 pounds buoyancy; and the inserts from child small size vests 
shall provide not less than 7 pounds buoyancy.
    (f) Body strap test. The complete body strap assembly including 
hardware, shall be tested for strength by attaching the dee ring to a 
suitable support such that the assembly hangs vertically its full 
length. A weight as specified in Sec.  160.052-3(d) shall be attached to 
the other end of the snap hook for 10 minutes. The specified weight 
shall not break or excessively distort the body strap assembly.
    (g) Additional approval tests for nonstandard vests. Tests in 
addition to those required by this section may be conducted by the 
inspector for nonstandard vests to determine performance equivalence to 
a standard vest. Such additional tests may include determining 
performance in water, suitability of materials, donning time, ease of 
adjustment, and similar equivalency tests. Costs of any additional tests 
must be assumed by the manufacturer.

plastic foam shall be installed in the rescue boat. This material shall 
be protected from mechanical damage. It shall be distributed uniformly 
in the boat and such that at least one-quarter of the required volume is 
located at the sides of the boat. The minimum amount of buoyant 
material, in cubic feet, shall be determined by the following:

B = 2 + (W - W / d) / 62.4 - c (1)

Where:

B = Volume of buoyant material required in cubic feet.
W = Weight of equipped boat, in pounds.
d = Specific gravity of hull material.
c = Density of buoyant material, in pounds per cubic foot.



Sec.  160.056-3  Fittings and equipment.

    (a) Fittings. (1) The rescue boat shall be fitted with one pair of 
rowlock sockets. Detachable rowlocks shall be permanently attached to 
the boat by chain or other suitable means.
    (2) At least one eyebolt, ring, or other fitting suitable for 
attaching a painter shall be fitted to the bow and stern.
    (b) Equipment. (1) The rescue boat shall be provided with one pair 
of oars of suitable size and material.
    (2) A painter shall be attached to the bow and to the stern 
fittings. Each shall be of suitable material, at least \3/8\-inch in 
diameter, and at least 30 feet long.



Sec.  160.056-4  Approval tests of prototype rescue boat.

    (a) Drop test. The rescue boat, fully equipped, shall be dropped, in 
a free fall, from a ten-foot height into water. No damage which would 
render the rescue boat unserviceable shall result from this drop.
    (b) Stability and freeboard test. The rescue boat shall have 
sufficient stability and freeboard so that the gunwale on the low side 
shall not be submerged with 350 pounds placed nine inches from the side 
in way of and about the level of the middle thwart.
    (c) Rescue boarding test. With one man in the rowing position, a 
second kneeling on the stern thwart facing aft, and a third man balanced 
on the transom, the minimum freeboard of the transom shall be five 
inches. The men should average 165 pounds each. This test simulates the 
rescue of a person over the transom by a two-man boat crew.

[[Page 135]]

    (d) Rowing test. Three men, averaging 165 pounds each, shall be 
seated on the centerline of the boat, one on each thwart. One man, in 
the rowing position, using ordinary rowing technique, shall demonstrate 
the satisfactory course keeping and maneuvering characteristics of the 
boat in the ahead and astern directions.

Sec.  160.057-2  Type.

    (a) Floating orange. smoke distress signals specified by this 
subpart shall be of one type which shall consist essentially of an outer 
container, ballast, an air chamber, an inner container, the smoke 
producing composition, and an igniter mechanism. Alternate arrangements 
which conform to the performance requirements of this specification will 
be given special consideration.
    (b) [Reserved]



Sec.  160.057-3  Materials, workmanship, construction, and performance
requirements.

    (a) Materials. The materials shall conform strictly to the 
specifications and drawings submitted by the manufacturer and approved 
by the Commandant. Metal for containers shall be not less than 0.5 mm 
(0.020 in.) in thickness. Other dimensions or materials may be 
considered upon special request when presented with supporting data. 
Igniter systems shall be of corrosion-resistant metal. The combustible 
material shall be of such nature that it will not deteriorate during 
long storage, nor when subjected to frigid or tropical climates, or 
both.
    (b) Workmanship. Floating orange smoke distress signals shall be of 
first class workmanship and shall be free from imperfections of 
manufacture affecting their appearance or that may affect their 
serviceability.
    (c) Construction. The outer container shall be cylindrical and of a 
size suitable for intended use. All sheet metal seams should be hook 
jointed and soldered. The whole container shall be covered with two 
coats of waterproof paint or other equivalent protection system. The 
igniter mechanism shall operate and provide ignition of the signal 
automatically when the ring life buoy to which it is attached is thrown 
overboard.
    (d) Performance. Signals shall meet all the inspection and test 
requirements contained in Sec.  160.057-4.



Sec.  160.057-4  Approval and production tests.

    (a) Approval tests. The manufacturer must produce a lot of at least 
20 signals from which samples must be taken for testing for approval 
under Sec.  160.057-7. The approval tests are the operational tests and 
technical tests in paragraphs (c) and (d) of this section. The approval 
tests must be conducted by an independent laboratory accepted by the 
Commandant under Sec.  159.010 of this chapter.
    (b) Production inspections and tests. Production inspections and 
tests of each lot of signals produced must be conducted under the 
procedures in Sec.  159.007 of this chapter. Signals from a rejected lot 
must not be represented as meeting this subpart or as being approved by 
the Coast Guard. If the manufacturer identifies the cause of the 
rejection of a lot of signals, the signals in the lot may be reworked by 
the manufacturer to correct the problem. Samples from the rejected lot 
must be retested in order to be accepted. Records shall be kept of the 
reasons for rejection, the reworking performed on the rejected lot, and 
the results of the second test.
    (1) Lot size. For the purposes of sampling the production of 
signals, a lot must consist of not more than 1,200 signals. Lots must be 
numbered serially by the manufacturer. A new lot must be started with: 
(i) Any change in construction details, (ii) any change in sources of 
raw materials, or (iii) the start of production on a new production line 
or on a previously discontinued production line.
    (2) Inspections and tests by the manufacturer. The manufacturer's 
quality control procedures must include inspection of materials entering 
into construction of the signals and inspection of the finished signals, 
to determine that signals are being produced in accordance with the 
approved plans. Samples from each lot must be tested in accordance with 
the operational tests in paragraph (c) of this section.

[[Page 137]]

    (3) Inspections and tests by an independent laboratory. An 
independent laboratory accepted by the Commandant under Sec.  159.010 of 
this chapter must perform or supervise the inspections and tests under 
paragraph (b)(2) of this section at least 4 times a year, unless the 
number of lots produced in a year is less than four. The inspections and 
tests must occur at least once during each quarterly period, unless no 
lots are produced during that period. If less than four lots are 
produced, the laboratory must perform or supervise the inspection and 
testing of each lot. In addition, the laboratory must perform or 
supervise the technical tests in paragraph (d) of this section at least 
once for every ten lots of signals produced, except that the number of 
technical tests must be at least one but not more than four per year. If 
a lot of signals tested by the independent laboratory is rejected, the 
laboratory must perform or supervise the inspections and tests of the 
reworked lot and the next lot of signals produced. The tests of each 
reworked lot and the next lot produced must not be counted for the 
purpose of meeting the requirement for the annual number of inspections 
and tests performed or supervised by the independent laboratory.
    (c) Operational tests. Each lot of signals must be sampled and 
tested as follows:
    (1) Sampling procedure and accept/reject criteria. A sample of 
signals must be selected at random from the lot. The size of the sample 
must be the individual sample size in Table 160.057-4(c)(1) 
corresponding to the lot size. Each signal in the sample is tested as 
prescribed in the test procedure in paragraph (c)(2) of this section. 
Each signal that has a defect listed in the table of defects (Table 
160.057-4(c)(2)) is assigned a score (failure percent) in accordance 
with that table. In the case of multiple defects, only the score having 
the highest numerical value is assigned to that signal If the sum of all 
the failure percents (cumulative failure percent) for the number of 
units in the sample is less than or equal to the accept criterion, the 
lot is accepted. If this sum is equal to or more than the reject 
criterion the lot is rejected.

If the cumulative failure percent falls between the accept and reject 
criteria, another sample is selected from the production lot and the 
operational tests are repeated. The cumulative failure percent of each 
sample tested is added to that of the previous samples to obtain the 
cumulative failure percent for all the signals tested (cumulative sample 
size). Additional samples are tested and the tests repeated until either 
the accept or reject criterion for the cumulative sample size is met. If 
any signal in the sample explodes when fired, or ignites in a way that 
could burn or otherwise injure the person firing it, the lot is rejected 
without further testing. (This procedure is diagrammed in figure 
160.057-4(c)).
    (2) Test procedure. Each sample signal (specimen) must be tested as 
follows:
    (i) Conditioning of test specimens--water resistance. Immerse 
specimen horizontally with uppermost portion of the signal approximately 
25 mm (1 in.) below the surface of the water for a period of 24 hours.
    (ii) Smoke emitting time. Ignite specimen according to the 
directions printed on the signal and place signal in tub or barrel of 
water. The smoke emitting time of a specimen shall be obtained by stop 
watch measurements from the time of distinct, sustained smoke emission 
until it ceases. There shall be no flame emission during the entire 
smoke emitting time of the signal. The smoke emitting time for a 
specimen shall not be less than 15 minutes. When the tests are performed 
or supervised by an independent laboratory, this test shall be conducted 
with approximately 6 mm (\1/4\ in.) of gasoline covering the water in 
the tub or barrel. The gasoline vapors shall not ignite during the 
entire smoke emitting time of the signal.
    (iii) Ignition and smoke emitting characteristics. Test specimens 
shall ignite and emit smoke properly when the directions on the signal 
are followed. Test specimens shall not ignite explosively in a manner 
that might be dangerous to the user or persons close by. Test specimens 
shall emit smoke at a uniform rate while floating in calm to rough 
water. Signals should be so constructed that water submerging the signal 
in moderately heavy seas will not cause it to become inoperable.

    (d) Technical tests. One signal must be subjected to each of the 
following tests. Each signal must pass the test in order for the lot of 
signals to be accepted.
    (1) Drop test. One signal must be attached to a ring life buoy and 
arranged

[[Page 140]]

to be ignited by the dropping buoy in the same manner as it would be 
when used on a vessel. The signal and buoy must be mounted at least 27 m 
(90 ft.) above the surface of a body of water. The buoy is released and 
must cause the signal to ignite and fall to the water with the buoy. The 
signal must remain afloat and emit smoke at least 15 minutes.
    (2) Wave test. A signal shall be tested in a manner simulating its 
use at sea. The signal shall be ignited and thrown overboard under 
conditions where waves are at least 30 cm (1 ft.) high. The smoke 
emitting time must be for the full 15 minutes and the signal shall float 
in such a manner that it shall function properly during this test. The 
signal shall be attached to a ring life buoy in accordance with the 
manufacturer's instructions.
    (3) Underwater smoke emission. Condition the signal in accordance 
with paragraph (c)(2)(i) of this section. Ignite specimen and let it 
burn about 15 seconds in air. Submerge the burning signal in water in a 
vertical position with head down. Obtain underwater smoke emission time 
by stop watch measurements from time of submersion until smoke emission 
ceases. The test specimen shall emit smoke under water not less than 30 
seconds when subjected to this test.
    (4) Elevated Temperature, Humidity and Storage. Place specimen in a 
thermostatically controlled even-temperature oven held at 75 [deg]C. 
with not less than 90 percent relative humidity for 72 hours. Remove 
specimen and store at room temperature (20[deg] to 25 [deg]C.) with 
approximately 65 percent relative humidity for 10 days. If for any 
reason it is not possible to operate the oven continuously for the 72-
hour period, it may be operated at the required temperature and humidity 
for 8 hours out of each 24 during the 72-hour conditioning period. 
(Total of 24 hours on and 48 hours off.) The signal shall not ignite or 
decompose during this conditioning. The signal shall ignite and operate 
satisfactorily following this conditioning.
    (5) Spontaneous ignition. Place the specimen in a thermostatically 
controlled even-temperature oven held at 75 [deg]C. with not more than 
10% relative humidity for 48 consecutive hours. The signal must not

------------------------------------------------------------------------

    (5) If a sample vest fails the buoyancy test, the sample from the 
next succeeding lot must consist of 10 specimen vests or more to be 
tested for buoyancy in accordance with paragraph (e) of this section.
    (c) Additional compliance tests. An inspector from the recognized 
laboratory or Coast Guard may conduct an examination, test and 
inspection of a buoyant device that is obtained from the manufacturer or 
through commercial channels to determine the suitability of the device 
for listing and labeling, or to determine its conformance to applicable 
requirements.
    (d) Test facilities. The manufacturer shall admit the laboratory 
inspector and the Coast Guard inspector to any part of the premises at 
the place of manufacture of a listed and labeled device to--
    (1) Examine, inspect, or test a sample of a part or a material that 
is included in the construction of the device; and
    (2) Conduct any examination, inspection, or test in a suitable place 
and with appropriate apparatus provided by the manufacturer.
    (e) Buoyancy--(1) Buoyancy test method. Remove the buoyant inserts 
from the vests. Securely attach the spring scale in a position directly 
over the test tank. Suspend the weighted wire basket from the scale in 
such a manner that the basket can be weighed while it is completely 
under water. In order to measure the actual buoyancy provided by the 
inserts, the underwater weight of the empty basket should exceed the 
buoyancy of the inserts. To obtain the buoyancy of the inserts, proceed 
as follows:
    (i) Weigh the empty wire basket under water.
    (ii) Place the inserts inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water. 
Allow the inserts to remain submerged for 24 hours. The tank shall be 
locked or sealed during this 24-hour submergence period. It is important 
that after the inserts have once been submerged they shall remain 
submerged for the duration of the test, and at no time during the course 
of the test shall they be removed from the tank or otherwise exposed to 
air.
    (iii) After the 24-hour submergence period, unlock or unseal the 
tank and weigh the wire basket with the inserts inside while both are 
still under water.

[[Page 146]]

    (iv) The buoyancy is computed as paragraph (e)(1)(i) of this section 
minus paragraph (e)(1)(iii) of this section.
    (2) Buoyancy required. The buoyant inserts from adult size buoyant 
vests shall provide not less than 15\1/2\ pounds of buoyancy in fresh 
water; the inserts from the child medium size buoyant vests shall 
provide not less than 11 pounds buoyancy; and the inserts from the child 
small size buoyant vests shall provide not less than 7 pounds buoyancy.
    (f) Body strap test. The complete body strap assembly, including 
hardware shall be tested for strength by attaching the dee ring to a 
suitable support such that the assembly hangs vertically its full 
length. A weight as specified in Sec.  160.060-3(d) shall be attached to 
the other end on the snap hook for 10 minutes. The specified weight 
shall not break or excessively distort the body strap assembly.
    (g) Additional approval tests for nonstandard vests. Tests in 
addition to those required by this section may be conducted by the 
inspector for a nonstandard vest to determine performance equivalence to 
a standard vest. Such additional tests may include determining 
performance in water, suitability of materials, donning time, ease of 
adjustment, and similar equivalency tests. Costs for any additional 
tests must be assumed by the manufacturer.

Sec.  160.062-2  Types.

    (a) The hydraulic releases referred to under Sec.  160.062-1(a)(1) 
are of the diaphram-spring plunger type, which releases a buoyant load 
under hydrostatic pressure.

[[Page 151]]

    (b) All hydraulic releases given an approval under this subpart 
shall be designed and tested to operate with spring-tensioned gripes. 
Such gripes shall be considered as a part of each approval.
    (c) Alternate designs will be given special consideration, but the 
expense of their preliminary investigation at a laboratory accepted by 
the Commandant shall be borne by the manufacturer.

Sec.  160.062-3  Materials, construction, workmanship, and 
performance requirements.

    (a) General. The materials, construction, workmanship, and 
performance requirements shall conform to the requirements of the 
specifications listed in Sec.  160.062-1(a)(1) except as otherwise 
provided by this subpart. In addition, all metals and materials used in 
a hydraulic release must be compatible with each other so that the final 
assembly under conditions of use is not subject to such deleterious 
effects as galvanic corrosion, freezing, or buckling of moving parts, or 
loosening and tightening of joints due to differences in coefficients of 
thermal expansion. Galvanizing or other forms of metallic coating on the 
parts of a hydraulic release are not acceptable. The criteria for 
accepting any combination of materials shall be determined by testing or 
by the data stated in Sec.  160.062-1(b).
    (b) Buoyant load capacity. A hydraulic release working in 
conjunction with its spring-tensioned gripe must demonstrate that it can 
release buoyant loads between the limits of 200 pounds and 3,750 pounds 
and within the range of depths specified by paragraph (c) of this 
section.
    (c) Release depth. A hydraulic release shall automatically release 
the buoyant loads described in paragraph (b) of this section at depths 
between 5 feet to 15 feet prior to being tested for either the 
temperature or the corrosion resistance tests of 160.062-4(c)(2). After 
exposure to these temperature and corrosion tests, a hydraulic release 
shall release the buoyant loads of paragraph (b) of this section between 
the depths of 5 feet to 25 feet.

    (1) Visual and dimensional examination. The marine inspector shall 
examine the 4 hydraulic release samples of the preapproval sample for 
their visual and dimensional characteristics. If all 4 of the devices 
are in agreement with the manufacturer's plans previously reviewed by 
the Commandant, the 4 devices will be accepted and are to be assembled 
for further testing under the ``Physical and operational tests'' of 
paragraph (c)(2) of this section.
    (2) Physical and operational tests. Each hydraulic release selected 
under Table 160.062-4(c) for the ``Physical and operational tests'' 
shall undergo each of the tests described in this paragraph without 
renewal of parts or repairs between the tests. The tests shall be 
conducted in the following sequence:
    (i) Submergence test. A hydraulic release shall be tested by 
applying buoyant loads of its designed capacity to its spring-tensioned 
gripe as required under Sec.  160.062-3(b) while the device is submerged 
in water or in a water-filled pressure testing tank. A hydraulic release 
shall show by its submergence test that it meets the buoyant capacity 
and release depth requirements of Sec.  160.062-3 (b) and (c) by 
automatically tripping and releasing its load.
    (ii) Temperature test. After its submergence test, a hydraulic 
release sample shall be placed in a cold box at minus 30 degrees F. for 
4 hours. Upon completion of this conditioning, the sample device shall 
be opened for inspection and shall show no significant change in the 
position of the hydraulic or manual control as a result of the low 
temperature exposure.
    (iii) Corrosion resisting test. After the completion of its 
temperature test, a hydraulic release sample shall be exposed to a 20 
percent salt spray test for 160 continuous hours in accordance with 
Federal Test Method Standard No. 151. At the conclusion of this test, 
the sample device shall be entirely serviceable and shall show a minimal 
amount of corrosion.
    (iv) Second temperature test. After its corrosion resisting test, a 
hydraulic release sample shall undergo a repeat of the temperature test, 
subdivision (ii) of this paragraph.
    (v) Second submergence test. The final test of a hydraulic release 
sample shall be a repeat of the submergence test, paragraph (c)(2)(i) of 
this section.
    (d) Factory inspections and tests. For purposes of sampling, a lot 
shall consist of not more than 500 hydraulic releases of the same model. 
Manufacturers of approved hydraulic releases shall maintain quality 
control of the materials used, manufacturing methods, workmanship, and 
the finished product as to produce hydraulic releases in conformity with 
the approvals previously issued by the Commandant.
    (1) Visual and dimensional examination. A random sample of hydraulic 
releases shall be selected by a marine inspector at the factory in 
accordance with Table 160.062-4(d)(1) from each assembled lot. After the 
samples have been selected, they will undergo an examination of visual 
and dimensional characteristics by referring to their approved drawings 
with their acceptance based on Table 160.062-4(d)(1) and MIL-STD-105, 
and checking for compliance with specific details as described therein.

  Specification MIL-R-15041C.

    (3) Lot acceptance at a factory. The submergence test of paragraph 
(c)(2)(i) shall be performed on each of the remaining hydraulic releases 
in a production lot after the selection of the lot samples required by 
paragraph (d)(2) of this section. Such individual submergence tests may 
be performed at the factory in a pressure tank apparatus which simulates 
the hydrostatic pressure and the various tension loads on the hydraulic 
release. Those hydraulic releases which do not pass this submergence 
test shall be removed from the production lot as unacceptable, but may 
be reworked and included in a subsequent lot. After the completion of 
these individual submergence tests and after receipt of the laboratory's 
test report showing that the tests on the lot samples were 
satisfactorily met, the Commander of the Coast Guard District in which 
the factory is located shall have the manufacturer notified that this 
production lot of hydraulic releases meets the requirements of this 
specification subpart. After being marked as required by Sec.  160.062-
5, the manufacturer may sell such hydraulic releases as approved 
equipment.
    (i) Hydraulic releases which have been rejected may not, unless 
subsequently accepted, be sold or offered for sale under representation 
as being in compliance with this specification or as being approved for 
use on vessels subject to inspection under this chapter.
    (4) Records and test reports. The manufacturer shall maintain 
records and copies of test reports for each production lot of hydraulic 
releases manufactured for a period of five (5) years from the date 
notified that a production lot meets the requirements in this subpart. 
These records and test reports, upon request, shall be made available to 
the marine inspector. The manufacturer will be provided with a copy of 
the laboratory's test report concerning each production lot of hydraulic 
releases submitted for testing.
    (e) Spot checks. As one of the conditions in granting an approval 
for a hydraulic release under this subpart, the Coast Guard reserves the 
right to spot check at any time and at any place the product, parts, and 
complete assemblies of hydraulic releases covered by the approval. The 
spot check shall be by a marine inspector who shall be admitted to the 
place or places where work may be performed before, during, or after the 
manufacture of hydraulic releases or at any place where hydraulic 
releases may be assembled, reworked, repaired, or reconditioned by the 
manufacturer of any repair facility accepted by the Commandant in 
accordance with the procedure contained in Sec.  160.062-7. A spot check 
includes having a marine inspector compare materials, parts, and 
workmanship and/or complete hydraulic releases with the manufacturer's 
approved plans, records and test reports to ascertain compliance with 
these requirements. The marine inspector may select samples of materials 
or parts used in the construction of hydraulic releases and complete 
hydraulic releases and may order or have performed any or all of the 
tests described in this section conducted on such devices or parts 
thereof. This work and any tests required shall be borne by the 
manufacturer without cost to the Coast Guard.

[CGD 76-183a, 44 FR 73050, Dec. 17, 1979, as amended by CGD 93-055, 61 
FR 13931, Mar. 28, 1996]



Sec.  160.066-12  Operational tests.

    (a) The procedure for conducting operational tests is described in 
figure (1).
    (1) An ``accept lot'' decision must be reached in order to pass the 
operational tests.
    (2) If a ``reject lot'' decision is reached, the entire lot is 
rejected.
    (3) Signals from ``reject lots'' may be reworked by the manufacturer 
to correct the deficiency for which they were rejected and be 
resubmitted for inspection. Records shall be kept of the reasons for 
rejection, the reworking performed on the ``reject lot'', and the result 
of the second test. Signals from ``reject lots'' may not, unless 
subsequently accepted, be sold or offered for sale as being in 
compliance with this specification.
    (b) Each signal selected for the operational tests must be 
conditioned by:
    (1) Being submerged under at least 25 mm (1 in.) of water for 24 
hours without any protection other than its waterproofing; or
    (2) If waterproofing is provided by a sealed plastic bag or other 
waterproof packaging, submersion under 25 mm (1 in.) of water for 24 
hours in the packaging, followed immediately by submersion under 25 mm 
(1 in.) of water for 10 minutes with the signal removed from the 
packaging.
    (c) After each signal selected has undergone the conditioning 
required by paragraph (b) of this section it must be fired as described 
by the manufacturer's operating instructions. The following data as 
observed must be recorded for each signal:
    (1) Burning time of the pyrotechnic candle;
    (2) Color;
    (3) Whether the pyrotechnic candle burns out above, at, or below the 
level of launch.
    (d) A signal fails the operational tests if:
    (1) It fails to fire,
    (2) The pyrotechnic candle fails to ignite,
    (3) The pyrotechnic candle continues to burn after it falls back to 
the level of launch,
    (4) The observed color is other than vivid red, or
    (5) The burning time is less than 5.5 seconds.
    (e) A lot is rejected if a ``reject lot'' decision is reached using 
Figure (1) and Table 1 after completion of the operational tests.

Sec.  160.066-13  Technical tests.

    (a) The following conditions apply to technical tests as described 
in this section:
    (1) A total of nine signals must be selected at random from the lot 
being tested;
    (2) If the signals are protected by sealed packaging, then the 
conditioning for the technical tests must be conducted with the signal 
in the sealed packaging;
    (3) If signals in the test sample fail to pass one of the technical 
tests, the entire lot is rejected;
    (4) Signals from ``reject lots'' may be reworked by the manufacturer 
to correct the deficiency for which they were rejected and be 
resubmitted for inspection. Records shall be kept of the reasons for 
rejection, the reworking performed on the ``reject lot'', and the result 
of the second test. Signals from ``reject lots'' may not, unless 
subsequently accepted, be sold or offered for sale as being in 
compliance with this specification.
    (b) The Elevated Temperature, Humidity, and Storage Test must be 
conducted in the following manner:
    (1) Select three signals from the nine;
    (2) Place each signal in a thermostatically controlled even-
temperature oven held at 55 Degrees C (131 Degrees F), and at not less 
than 90% relative humidity, for at least 72 hours (If for any reason it 
is not possible to operate the oven continuously for the 72 hour period, 
it may be operated at the required temperature and humidity for 8 hours 
of each 24 during the 72 hour conditioning period.);
    (3) After removal from the oven immediately place each signal in a 
chamber:

[[Page 163]]

    (i) At a temperature of at least 20 degrees C (68 degrees F) but not 
more than 25 degrees C (77 degrees F);
    (ii) At not less than 65% relative humidity;
    (iii) For ten days;
    (4) Then remove each signal from any sealed packaging and fire it.
    (5) The test sample fails the test if:
    (i) Any signal ignites or decomposes before firing;
    (ii) Any signal when fired malfunctions in a manner that would cause 
burns or injury to an unprotected person firing the signal, or;
    (iii) Two or more of the signals fail to project and ignite the 
pyrotechnic candle.
    (c) The Spontaneous Combustion Test must be performed in the 
following manner:
    (1) Select three signals from the remaining six signals and place 
them in a thermostatically controlled even temperature over for 48 hours 
at a temperature of 75 degrees C (167 degrees F).
    (2) The test sample fails the test if any signal ignites or 
decomposes during the test.
    (d) The Luminous Intensity and Chromaticity Test must be performed 
in the following manner:
    (1) Remove the pyrotechnic candle from the remaining three signals.
    (2) Ignite, measure, and record the intensity of the burning candle 
with a visual photometer or equivalent photometric device or automatic 
recorder:
    (i) While the specimen is supported in a horizontal position and the 
photometer is at right angles to the axis of the specimen,
    (ii) At a distance of at least 3 m (10 ft.).
    (3) Calculate the intensity of the candle as in Sec.  160.066-7(c).
    (4) Measure and record the chromaticity of the burning candle as 
specified in Sec.  160.021-4(d)(4).
    (5) The test sample fails the test if more than one signal has a 
luminous intensity of less than 10,000 candela, or more than one signal 
is not ``vivid red''.

least once every twelve months, or at least once every 10 lots, 
whichever occurs first.
    (d) If a lot is rejected on the basis of the technical tests, then 
each subsequent lot produced must be tested according to the technical 
tests until samples from a lot pass these tests.
    (e) An independent laboratory acceptable to the Commandant must 
perform or directly supervise:
    (1) Each technical test, and
    (2) All operational tests for at least four lots in a 12 month 
period, unless fewer than four lots are produced in a 12 month period. 
If less than four lots are produced in a 12 month period, each 
operational test must be performed or directly supervised by the 
independent laboratory.
    (f) If a lot selected by the independent laboratory for an 
operational test is rejected, then the operational tests for the next 
lot produced, and the rejected lot, if reworked, must be performed or 
directly supervised by the independent laboratory. The tests required by 
this paragraph must not be counted for the purpose of meeting the 
requirements of paragraph (e).
    (g) The independent laboratory selects the lots upon which technical 
tests are performed.
    (h) If the manufacturer produces more than four lots within a 12 
month period, the independent laboratory selects the lots for which it 
performs or directly supervises the operational tests.
    (i) The operational test performed or directly supervised by the 
independent laboratory must occur at least once during each quarterly 
period, unless no lots are produced during that period.
    (j) The independent laboratory, when it performs or directly

[[Page 170]]

to the same information as the inspectors of the laboratory that 
conducted the approval testing.
    (c) In addition to responsibilities set out in part 159 of this 
chapter and the accepted Laboratory Follow-up Procedures, each 
manufacturer of an inflatable PFD and each recognized laboratory 
inspector shall comply with the following, as applicable:
    (1) Manufacturer. Each manufacturer must--
    (i) Except as provided in paragraph (e)(2) of this section, perform 
all required tests and examinations on each PFD lot before any required 
inspector's tests and inspection of the lot;
    (ii) Follow established procedures for maintaining quality control 
of the materials used, manufacturing operations, and the finished 
product;
    (iii) Implement a continuing program of employee training and a 
program for maintaining production and test equipment;
    (iv) Admit the inspector to any place in the factory where work is 
done on PFDs or component materials, and where parts or completed PFDs 
are stored;
    (v) Have an inspector observe the production methods used in 
producing the first PFD lot and observe any revisions in production 
methods made thereafter; and
    (vi) Allow the inspector to take samples of completed PFDs or of 
component materials for tests required by this subpart and for tests 
relating to the safety of the design.
    (2) Recognized laboratory oversight. An inspector from a recognized 
laboratory shall oversee production in accordance with the MOU. During 
production oversight, the inspector shall not perform or supervise any 
production test or inspection unless--
    (i) The manufacturer has a valid approval certificate; and
    (ii) The inspector has first observed the manufacturer's production 
methods and any revisions to those methods.
    (3) The inspector must perform or supervise testing and inspection 
of at least one in each five lots of PFDs produced.
    (4) During each inspection, the inspector must check for compliance 
with the manufacturer's quality control procedures.
    (5) Except as provided in paragraph (c)(6) of this section, at least 
once each calendar quarter, the inspector must examine the 
manufacturer's records required by Sec.  160.076-33 and observe the 
manufacturer perform each of the tests required by Sec.  160.076-31(c).
    (6) If less than six lots are produced during a calendar year, only 
one lot inspection and one records' examination and test performance 
observation are required during that year. Each lot tested and inspected 
under paragraph (c)(3) of this section must be within seven lots of the 
previous lot inspected.
    (d) PFD lots. A lot number must be assigned to each group of PFDs 
produced. Lots must be numbered serially. A new lot must be started 
whenever any change in materials or a revision to a production method is 
made, and whenever any substantial discontinuity in the production 
process occurs. Changes in lots of component materials must be treated 
as changes in materials. The lot number assigned, along with the 
approval number, must enable the PFD manufacturer, by referring to the 
records required by this subpart, to determine the supplier of the 
components used in the PFD and the component supplier's identifying 
information for the component lot.
    (e) Samples. For the tests, examinations, and inspections required 
by Sec.  160.076-31, inspectors and manufacturers shall select samples 
as provided in this paragraph.
    (1) Samples shall be selected at random from a lot in which all PFDs 
or materials in the lot are available for selection. Except as provided 
in Sec.  160.076-31(c), samples must be selected from completed PFDs.
    (2) Different samples must be selected for the manufacturer's and 
inspector's tests, except, if the total production for any five 
consecutive lots does not exceed 250 PFDs, the manufacturer's and 
inspector's tests may be run on the same sample(s) at the same time.
    (3) The number of samples selected per lot must be at least equal to 
the applicable number required by Table 160.076-29A for manufacturers or 
Table 160.076-29B for inspectors.

test result must meet the requirements, if any, contained in the 
approved plans and specifications.
    (c) When conducting the tests specified by this paragraph, the 
following conditions must be met:
    (1) Inflation chamber materials. The materials in each inflatable 
chamber must comply with the requirements in Table 29.1 of UL 1191 
(incorporated by reference, see Sec.  160.076-11) for permeability, grab 
strength, and tear strength. Lots not meeting this requirement must be 
rejected and, unless authorized by the Commandant, may not be subdivided 
and retested.
    (2) Seam strength. The seams in each inflation chamber of each 
sample must be tested in accordance with Table 29.1 of UL 1191.
    (3) Over-pressure. Each sample must be tested in accordance with and 
meet UL 1180 (incorporated by reference, see Sec.  160.076-11) section 
41. Prior to initiating the test at the specified values, samples may be 
prestressed by inflating them to a greater pressure than the required 
test pressure.
    (4) Air retention. Each sample must be tested in accordance with and 
meet UL 1180 section 42. Prior to initiating the test at the specified 
values, test samples may be prestressed by inflating to a pressure 
greater than the design pressure, but not exceeding 50 percent of the 
required pressure for the tests in paragraph (c)(3) of this section. No 
alternate test method may be used that decreases the length of the test 
unless authorized by the Commandant. Such alternative test must require 
a proportionately lower allowable pressure loss and the same percentage 
sensitivity and accuracy as the standard allowable loss measured with 
the standard instrumentation.
    (5) Buoyancy and inflation medium retention. Each sample must be 
tested in

accordance with and meet UL 1180 section 29. Each buoyancy value must 
fall within the tolerances specified in the approved plans and 
specifications.
    (6) Tensile strength. Each sample primary closure system must be 
tested in accordance with and meet UL 1180 section 31.
    (7) Detailed product examination. Each sample PFD must be 
disassembled to the extent necessary to determine compliance with the 
following:
    (i) All dimensions and seam allowances must be within tolerances 
prescribed in the approved plans and specifications.
    (ii) The torque of each screw type mechanical fastener must be 
within its tolerance as prescribed in the approved plans and 
specifications.
    (iii) The arrangement, markings, and workmanship must be as 
specified in the approved plans and specifications and this subpart.
    (iv) The PFD must not contain any apparent defects.
    (8) Waterproof Marking Test. Each sample must be completely 
submerged in fresh water for at least 30 minutes. The sample must then 
be removed, immediately placed on a hard surface, and the markings 
vigorously rubbed with the fingers for 15 seconds. If the printing 
becomes illegible, the sample must be rejected.
    (d) Final lot examination and inspection--(1) General. On each PFD 
lot that passes production testing, the manufacturer shall perform a 
final lot examination and, on every fifth lot, a laboratory inspector 
shall perform a final lot inspection. Samples must be selected in 
accordance with paragraph Sec.  160.076-29(e). Each final lot must 
demonstrate--
    (i) First quality workmanship;
    (ii) That the general arrangement and attachment of all components, 
such as body straps, closures, inflation mechanisms, tie tapes, and 
drawstrings, are as specified in the approved plans and specifications;
    (iii) Compliance with the marking requirements in Sec.  160.076-39; 
and
    (iv) That the information pamphlet and owner's manual required by 
Sec.  160.076-35 and 160.076-37, respectively, are securely attached to 
the device, with the pamphlet selection information visible and 
accessible prior to purchase.
    (2) Accept/reject criteria. Each nonconforming PFD must be rejected. 
If three or more nonconforming PFDs are rejected for the same kind of 
defect, lot examination or inspection must be discontinued and the lot 
rejected.
    (3) Manufacturer examination. This examination must be conducted by 
a manufacturer's representative who is familiar with the approved plans 
and specifications, the functioning of the PFD and its components, and 
the production testing procedures. This person must not be responsible 
for meeting production schedules or be supervised by someone who is. 
This person must prepare and sign the record required by 159.007-13(a) 
of this chapter and 160.076-33(b).
    (4) Independent laboratory inspection. (i) The inspector must 
discontinue lot inspection and reject the lot if examination of 
individual PFDs or the records for the lot shows noncompliance with 
either this section or the laboratory's or the manufacturer's quality 
control procedures.
    (ii) If the inspector rejects a lot, the inspector must advise the 
Commandant or the recognized laboratory within 15 days.
    (iii) The inspector must prepare and sign the inspection record 
required by 159.007-13(a) of this chapter and 160.076-33(b). If the lot 
passes, the record must include the inspector's certification that the 
lot passed inspection and that no evidence of noncompliance with this

Sec.  160.077-23  Production tests and inspections.

    (a) General. (1) Production tests and inspections must be conducted 
in accordance with this section and subpart 159.007 of this chapter.
    (2) The Commandant may prescribe additional production tests and 
inspections if needed to maintain quality control and check for 
compliance with the requirements of this subpart.
    (b) Test and Inspection Responsibilities. In addition to 
responsibilities set out in part 159 of this chapter, each manufacturer 
of a hybrid PFD and each independent laboratory inspector must comply 
with the following, as applicable:
    (1) Manufacturer. Each manufacturer must--(i) Perform all required 
tests and examinations on each PFD lot before the independent laboratory 
inspector tests and inspects the lot, except as provided in Sec.  
160.077-23(d)(5);
    (ii) Perform required testing of each incoming lot of inflation 
chamber material before using that lot in production;
    (iii) Have procedures for maintaining quality control of the 
materials used, manufacturing operations, and the finished product;
    (iv) Have a continuing program of employee training and a program 
for maintaining production and test equipment;
    (v) Have an inspector from the independent laboratory observe the 
production methods used in producing the first PFD lot produced and 
observe any revisions made thereafter in production methods;
    (vi) Admit the inspector and any Coast Guard representative to any 
place in the factory where work is done on hybrid PFD's or component 
materials, and where completed PFD's are stored; and
    (vii) Allow the inspector and any Coast Guard representative to take 
samples of completed PFD's or of component materials for tests 
prescribed in this subpart.
    (2) Independent Laboratory. (i) An inspector may not perform or 
supervise any production test or inspection unless--
    (A) The manufacturer has a current approval certificate; and
    (B) The inspector has first observed the manufacturer's production 
methods and any revisions to those methods.
    (ii) Except as specified in paragraph (b)(2)(v) of this section, an 
inspector must perform or supervise testing and inspection of at least 
one PFD lot in each five lots produced.
    (iii) During each inspection, the inspector must check for 
noncompliance with the manufacturer's quality control procedures.
    (iv) Except as specified in paragraph (b)(2)(v) of this section, at 
least once each calendar quarter, the inspector must, as a check on the 
manufacturer's compliance with this section, examine the manufacturer's 
records required by Sec.  160.077-25 and observe the manufacturer 
perform each of the tests required by paragraph (h) of this section.
    (v) If less than six lots are produced during any calendar year, 
only one lot inspection in accordance with paragraph (b)(2)(ii) of this 
section, and one records examination and test performance observation in 
accordance with paragraph (b)(2)(iv) of this section is required during 
that year. Each lot tested and inspected must be within seven lots of 
the previous lot inspected.
    (c) PFD Lots. A lot number must be assigned to each group of PFD's 
produced. No lot may exceed 1000 PFD's. A new lot must be started 
whenever any change in materials or a production method is made, or 
whenever any substantial discontinuity in the production process occurs. 
Changes in lots of component materials must be treated as changes in 
materials. Lots must be numbered serially. The lot number assigned, 
along with the approval number, must enable the PFD manufacturer, by 
referring to the records required by this subpart, to determine who 
produced the components used in the PFD.
    (d) Samples. (1) Samples used in testing and inspections must be 
selected at

[[Page 186]]

random. Sampling must be done only when all PFD's or materials in the 
lot are available for selection.
    (2) Each sample PFD selected must be complete, unless otherwise 
specified in paragraph (h) of this section.
    (3) Each adult test subject must have a freeboard of at least:
    (i) 100 mm (4 inches) if the PFD being tested is to be approved as a 
Type I hybrid PFD; or
    (ii) 120 mm (4.75 inches) if the PFD being tested is to be approved 
as a SOLAS lifejacket.
    (4) The number of samples selected per lot must be at least the 
number listed in Table 160.077-23A or Table 160.077-23B, as applicable, 
except as allowed in paragraph (d)(5) of this section.

    (2) Accept/Reject Criteria. Each nonconforming PFD must be rejected. 
If three or more nonconforming PFD's are rejected for the same kind of 
defect, lot examination or inspection must be discontinued and the lot 
rejected.
    (3) Manufacturer Examination. This examination must be done by a 
manufacturer's representative who is familiar with the approved plans 
and specifications, the functioning of the PFD and its components, and 
the production testing procedures. This person must not be responsible 
for meeting production schedules or be supervised by someone who is. 
This person must prepare and sign the inspection record required by 
Sec.  159.077-13 of this chapter and Sec.  160.077-25(b).
    (4) Independent Laboratory Inspection. (i) The inspector must 
discontinue lot inspection and reject the lot if observation of the 
records for the lot or of individual PFD's shows noncompliance with this 
section or the manufacturer's quality control procedures.
    (ii) An inspector may not perform a final lot inspection unless the 
manufacturer has a current approval certificate.
    (iii) If the inspector rejects a lot, the inspector shall notify the 
Commandant immediately.
    (iv) The inspector must prepare and sign the record required by 
Sec.  159.077-13 of this chapter and Sec.  160.077-25(b). If the lot 
passes, the record must also include the inspector's certification to 
that effect and a certification that no evidence of noncompliance with 
this section was observed.
    (k) Disposition of PFD's Rejected in Testing or Inspections. (1) A 
rejected PFD lot may be resubmitted for testing, examination, or 
inspection if the manufacturer first removes and destroys each PFD 
having the same type of defect or, if authorized by the Commandant or an 
authorized representative of the Commandant, reworks the lot to correct 
the defect.
    (2) Any PFD rejected in a final lot examination or inspection may be 
resubmitted for examination or inspection if all defects have been 
corrected and reexamination or reinspection is authorized by the 
Commandant or an authorized representative of the Commandant.
    (3) A rejected lot or rejected PFD may not be sold or offered for 
sale with the representation that it meets this subpart or that it is 
Coast Guard approved.

    (1) The text in UL 1517, Section 39, item A;
    (2) The following text and illustrations:

           There Are Five Types of Personal Flotation Devices

    This is a Type [insert approved Type] Hybrid Inflatable PFD.

    Note: The following types of PFDs are designed to perform as 
described in calm water and when the wearer is not wearing any other 
flotation material (such as a wetsuit).
    Type I--A Type I PFD has the greatest required inherent buoyancy and 
turns most unconscious persons in the water from a face down position to 
a vertical and slightly backward position, therefore greatly increasing 
one's chances of survival. The Type I PFD is suitable for all waters, 
especially for cruising on waters where rescue may be slow coming, such 
as large bodies of water where it is not likely that boats will be 
nearby. This type PFD is the most effective of all types in rough water. 
It is reversible and available in only two sizes--Adult (over 40 kg (90 
lb)) and child (less than 40 kg (90 lb)) which are universal sizes 
(designed for all persons in the appropriate category).

[Insert illustration of Type I PFD]

    Type II--A Type II PFD turns most wearers to a vertical and slightly 
backward position in the water. The turning action of a Type II PFD is 
less noticeable than the turning action of a Type I PFD and the Type II 
PFD will not turn as many persons under the same conditions as the Type 
I. The Type II PFD is usually more comfortable to wear than the Type I. 
This type of PFD is designed to fit a wide range of people for easy 
emergency use, and is available in the following sizes: Adult (over 40 
kg (90 lb)), Medium Child (23-40 kg (50-90 lb)), and two categories of 
Small Child (less than 23 kg (50 lb) or less than 14 kg (30 lb). 
Additionally, some models are sized by chest sizes. You may prefer to 
use the Type II where there is a good chance of fast rescue, such as 
areas where it is common for other persons to be engaged in boating, 
fishing and other water activities.

[Insert illustration of Type II PFD]

    Type III--The Type III PFD allows the wearer to tilt backwards in 
the water, and the device will maintain the wearer in that position and 
will not turn the wearer face

[[Page 191]]

down. It is not designed to turn the wearer face up. A Type III is 
generally more comfortable than a Type II, comes in a variety of styles 
which should be matched to the individual use, and is often the best 
choice for water sports, such as skiing, hunting, fishing, canoeing, and 
kayaking. This type PFD normally comes in many chest sizes and weight 
ranges; however, some universal sizes are available. You may also prefer 
to use the Type III where there is a probability of quick rescue such as 
areas where it is common for other persons to be engaged in boating, 
fishing, and other water activities.

[Insert illustration of Type III PFD]

    Hybrid Inflatable Type I, II, or III--A Type I, II, or III Hybrid 
PFD is an inflatable device which is the most comfortable PFD to wear 
and has a minimal amount of buoyancy when deflated and significantly 
increased buoyancy when inflated (See accompanying table for actual 
buoyancy for your Type of hybrid). When inflated it turns the wearer 
with the action of a Type I, II, or III PFD as indicated on its label. 
Boaters taking advantage of the extra comfort of hybrid inflatable PFDs 
must take additional care in the use of these devices. Boaters should 
test their hybrid PFDs in the water, under safe, controlled conditions 
to know how well the devices float them with limited buoyancy. 
Approximately 90 percent of boaters will float while wearing a Type II 
or III hybrid inflatable PFD when it is not inflated. However, hybrid 
inflatable PFDs are not recommended for non-swimmers unless worn with 
enough additional inflation to float the wearer. Almost all boaters will 
float while wearing a Type I hybrid inflatable PFD that is not inflated. 
The PFD's `performance type' indicates whether it should be used only 
where help is nearby, or if it also may be used where help may be slow 
coming. Type I hybrids are suitable where rescue may be slow coming, 
while Types II and III are good only when there is a chance of fast 
rescue. Type I hybrids are approved in three weight ranges, adult, for 
persons weighing over 40 kg (90 lb); youth, for persons weighing 23-40 
kg (50-90 lb); and small child, for persons weighing 14-23 kg (30-50 
lb). Type II hybrid PFDs are approved in the same size ranges as Type I 
hybrids but may be available in a number of chest sizes and in universal 
adult sizes. Type III hybrids are only approved in adult and youth sizes 
but may also be available in a number of chest sizes and in universal 
adult sizes.

[For a pamphlet provided with a Type I, II or III hybrid PFD, insert 
illustration of the Type Hybrid PFD being sold]

    Type IV--A Type IV PFD is normally thrown or tossed to a person who 
has fallen overboard so that the person can grasp and hold the device 
until rescued. Until May 15, 1995 (or May 1, 1996 at commercial 
liveries), the Type IV is acceptable in place of a wearable device in 
certain instances. However, this type is suitable only where there is a 
good chance of quick rescue, such as areas where it is common for other 
persons to be nearby engaged in boating, fishing, and other water 
activities. It is not recommended for use by non-swimmers and children.

[Insert illustration of Type IV PFD]

    Type V (General)--A Type V PFD is a PFD approved for restricted uses 
or activities such as boardsailing, or commercial white water rafting. 
These PFDs are not suitable for other boating activities. The label on 
the PFD indicates the kinds of activities for which the PFD may be used 
and whether there are limitations on how it may be used.
    Type V Hybrid--A Type V Hybrid PFD is an inflatable device which can 
be the most comfortable and has very little buoyancy when it is not 
inflated, and considerably more buoyancy when it is inflated. In order 
for the device to count toward carriage requirements on recreational 
boats, it must be worn except when the boat is not underway or when the 
user is below deck. When inflated it turns the wearer similar to the 
action provided by a Type I, II, or III PFD (the type of performance is 
indicated on the label). This type of PFD is more comfortable because it 
is less bulky when it is not inflated. Boaters taking advantage of the 
extra comfort of hybrid inflatable PFDs must take additional care in the 
use of these devices. Boaters should test their hybrid PFDs in the 
water, under safe, controlled conditions to know how well the devices 
float them with limited buoyancy. Approximately 70 percent of boaters 
will float while wearing a Type V hybrid PFD when the device is not 
inflated. Therefore, it is not recommended for non-swimmers unless worn 
with enough additional inflation to float the wearer. The PFD's 
``performance type'' indicates whether it should be used only where help 
is nearby, or if it may also be used where help may be slow coming. This 
type of PFD is approved in two sizes, adult, for persons weighing over 
40 kg (90 lb); and youth, for persons weighing 23-40 kg (50-90 lb), and 
may be available in a number of chest sizes and in universal adult 
sizes.

Sec.  160.077-29  PFD Manuals.

    (a) Approval. The text of each manual required by this section is 
reviewed with the application for approval. Changes may be required if 
needed to comply with this section.
    (b) Required Manuals. An owner's manual must be provided with each 
recreational and commercial hybrid PFD sold or offered for sale as 
follows:
    (1) The manual text for a recreational hybrid PFD must be printed 
verbatim and in the sequence set out in paragraph (c) or (d) of this 
section, as applicable.
    (2) The manual for a commercial hybrid PFD must meet the 
requirements of paragraph (f) of this section except that the manual for 
a commercial Type I PFD which is also labeled for recreational use must 
meet the requirements of paragraph (c) of this section.
    (3) Additional information, instructions, or illustrations may be 
included within the specified text of the manuals required by this 
section if there is no contradiction to the required information.
    (c) Type I, II or III Hybrid PFD. For a Type I, II and III hybrid 
PFD the manual contents must be as follows:
    (1) The following text:

                           Hybrid Limitations

    This PFD has limited inherent buoyancy which means YOU MAY HAVE TO 
INFLATE THIS PFD TO FLOAT, and its inflatable portion requires 
maintenance. While these PFDs are not required to be worn, if you have 
an accident or fall overboard, you are much more likely to survive if 
you are already wearing a PFD.
    There is only one way to find out if you will float while wearing 
the PFD when it is not inflated. That is to try this PFD in the water as 
explained in [insert reference to the section of the manual that 
discusses how to test the PFD]. If you have not tested this device in 
accordance with these guidelines, the Coast Guard does not recommend its 
use.

    (2) Instructions on use including instructions on donning, 
inflation, replenishing inflation mechanisms, and recommended practice 
operation;
    (3) Instructions on how to properly inspect and maintain the PFD, 
and recommendations concerning frequency of inspection;
    (4) Instructions on how to get the PFD repaired;
    (5) The text in UL 1517, Section 40, items B and D;
    (6) The following text:

                         Why Do You Need a PFD?

    A PFD provides buoyancy to help keep your head above water and to 
help you stay face up. The average in-water-weight of an adult is only 
about 5 to 10 pounds. The buoyancy provided by most PFDs will support 
that weight in water. However, the hybrid Type I, II, or III PFD may be 
an exception. The uninflated buoyancy provided by this PFD may only 
float 90 percent of the boating public. This is because the inherent 
buoyancy has been reduced to make it more comfortable to wear. So, you 
may not float adequately without inflating the device. Once the device 
is inflated you will have a minimum of 22 lb of buoyancy for adult 
sizes, which should be more than enough to float everyone. (See table 
above [below] for the actual minimum buoyancy for different Types of 
hybrids.) Your body weight alone does not determine your in-water-
weight. Since there is no simple method of determining your weight in 
water, you should try the device in the water in both its deflated and 
inflated condition.

    (7) The text in UL 1517, Section 40, item G;
    (8) The following text:

                              Wear Your PFD

    Your PFD won't help you if you don't have it on. It is well-known 
that most boating accidents occur on calm water during a clear sunny 
day. It is also true that in approximately 80 percent of all boating 
accident fatalities, the victim did not use a PFD. Don't wait until it's 
too late. Non-swimmers and children especially should wear their PFD at 
all times when on or near the water. Hybrid Type I, II, III or V PFDs 
are not recommended for non-swimmers unless inflated enough to float the 
wearer.

    (9) The text in UL 1517, Section 40, items I, J, K, and L; and
    (10) A table with the applicable PFD Type, size, and buoyancy values 
from Table 160.077-15(b)(13) or 160.077-17(b)(11), as applicable, or 
provide a reference to appropriate pamphlet table, if the pamphlet is 
combined with the manual.

production of release mechanisms, together with records identifying the 
lot or serial numbers of the release mechanisms in which such materials 
were used.
    (d) Tests--(1) Prototype release mechanism readiness. All tests must 
be conducted on a complete release mechanism.
    (2) IMO Revised recommendation on testing. Each prototype release 
mechanism of each design must pass each of the tests described in IMO 
Revised recommendation on testing, as amended by Resolution MSC.321(89), 
part 1, paragraph 6.9 (incorporated by reference, see Sec.  160.133-5 of 
this subpart) applicable to davit-launched or free-fall lifeboats. Tests 
must be conducted in accordance with these paragraphs of IMO Revised 
recommendation on testing, as amended by Resolution MSC.321(89),Part 1, 
with the following modifications--

inspected to confirm--
    (A) Compliance with this subpart;
    (B) Conformance with the examined plans; and
    (C) Ease of operation and maintenance;
    (ii) Operation. Operation of the off-load control, for a davit-
launched boat, must be tested to confirm that the release lever cannot 
be shifted to release the boat in either the full load or light load 
condition. For a free-fall boat, the operation of the hook release must 
be demonstrated using both activation systems and may be tested without 
launching the boat;
    (iii) Tensile tests. The release mechanism hook assembly and 
supporting structure must be tensile tested in a jig built to load the 
hook assembly in the same way it would be loaded when installed in a 
boat. The hook assembly will be approved for a maximum of one-sixth of 
the highest load applied without failure;
    (iv) Universal joints. This test is required if the release 
mechanism employs universal joints to transmit the release power from 
the control to the hook release. One of each type and size of universal 
joint must be set up in a jig with the angles of leads set at 0 (zero), 
30, and 60 degrees, respectively. A torque of 540 Nm (400 ft lb) must be 
applied. This torque must be applied with the connecting rod secured 
beyond the universal and with the lever arm in the horizontal position. 
There must be no permanent set, or undue stress, as a result of this 
test; and
    (v) Hydraulic controls. If the release mechanism includes a fluid 
power and control system, a test of the hydraulic controls must be 
conducted in accordance with 46 CFR 58.30-35.
    (e) Test waiver. The Commandant may waive certain tests for a 
release mechanism identical in construction to smaller and larger 
release mechanisms that have successfully completed the tests. However, 
stress calculations in accordance with Sec.  160.133-9(b)(3) of this 
subpart must still be submitted. Tests associated with release mechanism 
components that have already been accepted by the Commandant are not 
required to be repeated.
    (f) At the request of the manufacturer and discretion of the 
Commandant, an independent laboratory may perform approval inspections 
and witness approval tests required by this section so long as the 
inspections and tests are performed and witnessed in accordance with the 
procedures agreed upon between the independent laboratory and Commandant 
under 46 CFR part 159, subpart 159.010.
    (g) After completion of approval inspections and tests required by 
this section, the manufacturer must comply with the requirements of 46 
CFR 159.005-9(a)(5) by preparing and submitting to the Commandant for 
review--

Sec.  160.135-11  Fabrication of prototype lifeboats for approval.

    (a) If the manufacturer is notified that the information submitted 
in accordance with Sec.  160.135-9 of this subpart is satisfactory to 
the Commandant, the manufacturer may proceed with fabrication of the 
prototype lifeboat as set forth in this section.
    (b) Unless the Commandant directs otherwise, an independent 
laboratory must perform or witness, as appropriate, inspections, tests, 
and oversight required by this section. Prototype inspections and tests 
of a lifeboat must be carried out in accordance with the procedures for 
independent laboratory inspection in 46 CFR part 159, subpart 159.007 
and in this section, unless the Commandant authorizes alternative tests 
and inspections. The Commandant may prescribe additional prototype tests 
and inspections necessary to maintain quality control and to monitor 
compliance with the requirements of this subpart.
    (c) Fabrication of a lifeboat must proceed in the following 
sequence:
    (1) The manufacturer must arrange for an independent laboratory (or 
Coast Guard inspector if required under paragraph (b) of this section) 
to inspect, test, and oversee the lifeboat during its fabrication and 
prepare an inspection and test report meeting the requirements of 46 CFR 
159.005-11.
    (2) The independent laboratory must make such inspections as are 
necessary to determine that the prototype is constructed by the methods 
and with the materials specified in the plans reviewed under Sec.  
160.135-9 of this subpart. By conducting at least one inspection during 
its construction, the independent laboratory must determine the 
prototype lifeboat conforms with those plans by inspecting--
    (i) Fiber Reinforced Plastic (FRP) Construction. (A) FRP components 
of each prototype lifeboat outer hull and any FRP inner hull or liner 
components that are bonded or bolted to the outer hull must have a layup 
made of unpigmented clear resins so that details of construction are 
visible for inspection. Test panels representative of each prototype 
layup must be tested in accordance with MIL-P-17549D(SH) (incorporated 
by reference, see Sec.  160.135-5 of this subpart). If an accepted MIL-
R-21607E(SH) (incorporated by reference, see Sec.  160.135-5 of this 
subpart) Grade B resin is used for the prototype lifeboat, additives for 
fire retardancy must not be used so that the laminate is translucent for 
inspection purposes. Any prototype test lifeboat with Grade B resins 
will not be marked in accordance with Sec.  160.135-17 of this subpart 
for use as a production lifeboat regardless of the outcome of the 
performance tests. Whichever accepted resin the manufacturer decides to 
use for the prototype lifeboat, the same resin must be used in the 
production lifeboats.

[[Page 224]]

    (B) The hull, canopy, and major structural laminates of each 
prototype FRP lifeboat must be tested for resin content, ultimate 
flexural strength, and tensile strength. The test samples must be cut 
out from the prototype lifeboat, or be laid up at the same time, using 
the same procedures and by the same operators as the laminate used in 
the lifeboat. The number of samples used for each test, and the 
conditions and test methods used, must be as per the applicable test 
specified in this paragraph. The resin content must be determined as per 
ASTM D 2584 or ISO 1172 (incorporated by reference, see Sec.  160.135-5 
of this subpart). The flexural ultimate strength must be determined by 
ASTM D 790 method I (test condition ``A'', flatwise, dry) or the 
corresponding ISO 14125 test method (incorporated by reference, see 
Sec.  160.135-5 of this subpart). The tensile strength, lengthwise, must 
be determined as per ASTM D 638 or ISO 527 (incorporated by reference, 
see Sec.  160.135-5 of this subpart).
    (C) Each major FRP component, such as the hull, canopy, and inner 
liner(s), of each prototype FRP lifeboat must be examined and weighed 
after it is completed but before it is assembled. If the lifeboat is 
constructed by the spray lay-up technique, the hull and canopy 
thicknesses must be measured using ultrasonic or equivalent techniques;
    (ii) Steel construction. Steel sheet and plate used for the hull, 
floors, and other structural components of a prototype steel lifeboat 
must meet the bend tests requirement specified under ASTM A 653 
(incorporated by reference, see Sec.  160.135-5 of this subpart) after 
galvanizing or other anti-corrosion treatment has been applied. This may 
be demonstrated through a supplier's certification papers or through 
witnessing actual tests;
    (iii) Coated cloth for partially enclosed lifeboats. Cloth material 
used in the construction of each prototype lifeboat must be confirmed to 
have met the requirements specified under Sec.  160.135-7(b)(28) of this 
subpart. This may be demonstrated through a supplier's certification 
papers or through witnessing actual tests;
    (iv) Welding. Structural components of each prototype lifeboat 
joined by welding must be welded by the welding procedures and materials 
as per the plans reviewed under Sec.  160.135-9 of this subpart and by 
welders appropriately qualified;
    (v) Buoyancy foam. Each major subassembly of a prototype lifeboat, 
such as the hull with liner and canopy with liner, must be weighed after 
the buoyancy foam is installed and before it is further assembled;
    (vi) Installation of the propulsion system;
    (vii) Installation of the steering system; and
    (viii) Installation of the water spray fire-protection and air 
support system(s), if fitted.
    (3) The independent laboratory must submit the inspection report to 
the Commandant.



Sec.  160.135-13  Approval inspections and tests for prototype lifeboats.

    (a) After the Commandant notifies the manufacturer that the 
prototype lifeboat is in compliance with the requirements of Sec.  
160.135-11 of this subpart, the manufacturer may proceed with the 
prototype approval inspections and tests required under this section. 
The prototype lifeboat, the construction of which was witnessed under 
Sec.  160.135-11 of this subpart, must be used for the tests in this 
section.
    (b) Except as provided in paragraph (f) of this section, the Coast 
Guard must conduct the approval inspections and witness the approval 
tests required under this section.
    (c) Manufacturer requirements. To proceed with approval inspections 
and tests required by this section, the manufacturer must--
    (1) Notify the Commandant and cognizant Officer in Charge, Marine 
Inspection (OCMI) of where the approval inspections and tests required 
under this section will take place, and such notification must be in 
sufficient time to allow making travel arrangements;
    (2) Arrange a testing schedule that allows for a Coast Guard 
inspector to travel to the site where the testing is to be performed;
    (3) Admit the Coast Guard inspector to any place where work or 
testing is

[[Page 225]]

performed on lifeboats or their component parts and materials for the 
purpose of--
    (i) Conducting inspections as necessary to determine that the 
prototype is constructed by the methods and with the materials specified 
in the plans reviewed under Sec.  160.135-9 of this subpart and the 
inspection report under Sec.  160.135-11 of this subpart;
    (ii) Assuring that the quality assurance program of the manufacturer 
is satisfactory;
    (iii) Witnessing tests; and
    (iv) Taking samples of parts or materials for additional inspections 
or test; and
    (4) Make available to the Coast Guard inspector the affidavits or 
invoices from the suppliers of all essential materials used in the 
production of lifeboats, together with records identifying the lot or 
serial numbers of the lifeboats in which such materials were used.
    (d) Tests. (1) Prototype lifeboat readiness. All tests must be 
conducted on a completely outfitted lifeboat, including fixed equipment 
such as compass, searchlight, and navigating lights. Loose equipment may 
be substituted by weights.
    (2) Fiber Reinforced Plastic (FRP) prototype lifeboat lay-up. For 
the prototype of each design of an FRP lifeboat, the lay-up must be made 
of unpigmented resins and clear gel coat.
    (3) Fuel tank. Each non-portable fuel tank must be tested by a 
static head above the tank top of 3 m (10 ft) of water without showing 
any leaks or signs of permanent distortion.
    (4) IMO Revised recommendation on testing. Each prototype lifeboat 
of each design must pass each of the tests for davit-launched or free-
fall lifeboats, as applicable, described in the IMO Revised 
recommendation on testing, part 1, paragraphs 6.1 through 6.17 
(incorporated by reference, see Sec.  160.135-5 of this subpart). Tests 
must be conducted in accordance with these paragraphs of IMO Revised 
recommendation on testing, Part 1, with the following modifications:
    (i) Fire retardancy/release mechanism and engine tests (Paragraphs 
1/6.2, 6.9, 6.10, 6.14). The tests in the following IMO Revised 
recommendation on testing paragraphs may be accomplished independent of 
the lifeboat, and may be considered completed and need not be repeated 
if the tests have been previously shown to meet the necessary 
requirements--
    (A) Paragraph 6.2;
    (B) Paragraphs 6.9.3 through 6.9.6;
    (C) Paragraph 6.10.2 through 6.10.6; and
    (D) Paragraphs 6.14.6 through 6.14.8.
    (ii) Lifeboat overload test (Paragraph 1/6.3). For a davit launched 
lifeboat, the overload test must be conducted with the lifeboat 
suspended from the lifting hooks. During this test, the canopy of a 
free-fall lifeboat must not deform so as to harm any potential 
occupants.
    (iii) Impact test (Paragraph 1/6.4). The rigid vertical surface must 
not be displaced or deformed as a result of the test.
    (iv) Lifeboat seating space test (Paragraph 1/6.7). The average mass 
of persons used to test the lifeboat seating space must be determined by 
weighing as a group or individually. Each person must wear an inherently 
buoyant SOLAS lifejacket with at least 150 N of buoyancy or a Coast 
Guard-approved lifejacket approved under approval series 160.155. For 
other than a totally enclosed lifeboat, the operator(s) must demonstrate 
that the lifeboat can be operated while wearing a Coast Guard approved, 
insulated-buoyant immersion suit approved under approval series 160.171. 
The Commandant will give consideration to requests to test at, and 
designate lifeboats for, a heavier occupant weight than that stated in 
the IMO LSA Code, Chapter IV (incorporated by reference, Sec.  160.135-5 
of this subpart).
    (v) Flooded stability test (Paragraph 1/6.8). Any materials used to 
raise the test weights representing the lifeboat occupants above the 
seat pan must be at least as dense as fresh water.
    (vi) Lifeboat operational test, Operation of engine (Paragraph 1/
6.10.1). For the 4-hour lifeboat maneuvering period, the lifeboat must 
not (except for a short period to measure towing force and to 
demonstrate towing fixture durability) be secured, and must be run 
through its full range of speeds and full range of all controls 
throughout the period.

[[Page 226]]

    (vii) Survival recovery test (Paragraph 1/6.10.8). The recovery 
demonstration must show that no more than two crewmembers are required 
to recover a helpless person of ninety-fifth percentile by weight 
described in ASTM F 1166 (incorporated by reference, see Sec.  160.135-5 
of this subpart) while the crewmembers and helpless person are each 
wearing a lifejacket.
    (viii) Flooded capsizing test (Paragraph 1/6.14.3-.5). For any 
lifeboat also approved as a rescue lifeboat, the lifeboat must return to 
an upright position and, without undue delay, the crew must be able to 
use the lifeboat again as a lifeboat.
    (ix) Fire test (Paragraph 1/6.16.4). The locations where 
temperatures are measured along with the rationale for the proposed 
locations must be provided to the Commandant for approval prior to the 
testing.
    (x) Water spray tests (Paragraph 1/6.16.9). The delivery rate of 
water, or the sprayed water film thickness over the lifeboat, must be at 
least equivalent to that used to achieve passing results for the fire 
test. Full coverage must be obtained without the need to rock the 
lifeboat or induce wetting by wiping or applying any agent.
    (xi) Measuring and evaluating acceleration forces (Paragraph 1/
6.17.5). For free-fall lifeboats, the selection, placement, and mounting 
of the accelerometers along with the rationale for the proposed 
selection, placement, and mounting must be provided to the Commandant 
for approval prior to the testing.
    (xii) Evaluation acceleration forces with the dynamic response model 
(Paragraph 1/6.17.9). For free-fall lifeboats only, sections 6.17.9 thru 
6.17.12 must be used along with the displacement limits for lifeboats in 
Table 2 under ``Evaluation with the dynamic response model''.
    (5) Visual inspection. Each lifeboat must be visually inspected to 
confirm--
    (i) Compliance with this subpart;
    (ii) Conformance with plans reviewed under Sec.  160.135-9 of this 
subpart; and
    (iii) Ease of operation and maintenance.
    (e) Test waiver. The Commandant may waive certain tests for a 
lifeboat identical in construction to smaller and larger lifeboats that 
have successfully completed the tests. Tests associated with lifeboat 
components that have already been approved by the Commandant are not 
required to be repeated.
    (f) At the request of the manufacturer and discretion of the 
Commandant, an independent laboratory may perform approval inspections 
and witness approval tests required by this section so long as the 
inspections and tests are performed and witnessed in accordance with the 
procedures agreed upon between the independent laboratory and Commandant 
under 46 CFR part 159, subpart 159.010.
    (g) After completion of approval inspections and tests required by 
this section, the manufacturer must comply with the requirements of 46 
CFR 159.005-9(a)(5) by preparing and submitting to the Commandant for 
review--
    (1) The prototype approval test report containing the same 
information recommended by IMO MSC Circ. 980 (incorporated by reference, 
see Sec.  160.135-5 of this subpart). The report must include a signed 
statement by the Coast Guard inspector (or independent laboratory as 
permitted by paragraph (f) of this section) who witnessed the testing, 
indicating that the report accurately describes the testing and its 
results; and
    (2) The final plans of the lifeboat as built. The plans must 
include, in triplicate--
    (i) The instructions for training and maintenance described in 
Sec. Sec.  160.135-19 and 160.135-21 of this subpart; and
    (ii) The final version of the plans required under Sec.  160.135-9 
of this subpart.
    (h) The Commandant will review the report and plans submitted under 
paragraph (g) of this section, and if satisfactory to the Commandant, 
will approve the plans under 46 CFR 159.005-13.



Sec.  160.135-15  Production inspections, tests, quality control,
and conformance of lifeboats.

    (a) Unless the Commandant directs otherwise, an independent 
laboratory must perform or witness, as appropriate, inspections, tests, 
and oversight required by this section. Production inspections and tests 
of lifeboats must be

[[Page 227]]

carried out in accordance with the procedures for independent laboratory 
inspection in 46 CFR part 159, subpart 159.007 and in this section, 
unless the Commandant authorizes alternative tests and inspections. The 
Commandant may prescribe additional production tests and inspections 
necessary to maintain quality control and to monitor compliance with the 
requirements of this subpart.
    (b) Manufacturer's responsibility. The manufacturer must--
    (1) Institute a quality control procedure to ensure that all 
production lifeboats are produced to the same standard, and in the same 
manner, as the prototype lifeboat approved by the Commandant. The 
manufacturer's quality control personnel must not work directly under 
the department or person responsible for either production or sales;
    (2) Schedule and coordinate with the independent laboratory (or 
Coast Guard inspector if required under paragraph (a) of this section) 
to ensure that all tests are performed as described in this section;
    (3) Submit to the Commandant, a yearly report that contains the 
following--
    (i) Serial number and date of final assembly of each lifeboat 
constructed;
    (ii) Name of the representative of the independent laboratory (or 
Coast Guard inspector if required under paragraph (a) of this section); 
and
    (iii) Name of the vessel and company receiving the lifeboat, if 
known; and
    (4) Ensure that the arrangement and materials entering into the 
construction of the lifeboat are in accordance with plans approved under 
Sec.  160.135-13(h) of this subpart;
    (5) Allow an independent laboratory (or Coast Guard inspector if 
required under paragraph (a) of this section) access to any place where 
materials are stored for the lifeboat, work or testing is performed on 
lifeboats or their component parts and materials, or records are 
retained to meet the requirements of paragraph (c) of this section, for 
the purpose of--
    (i) Assuring that the quality control program of the manufacturer is 
satisfactory;
    (ii) Witnessing tests; or
    (iii) Taking samples of parts or materials for additional 
inspections or tests; and
    (6) Ensure that the independent laboratory (or Coast Guard inspector 
if required under paragraph (a) of this section) conducts the 
inspections and witnesses the tests required by paragraph (e)(2) of this 
section, and further conducts a visual inspection to verify that the 
lifeboats are being made in accordance with the plans approved under 
Sec.  160.135-13(h) of this subpart and the requirements of this 
subpart.
    (c) Recordkeeping. The manufacturer must maintain records in 
accordance with 46 CFR 159.007-13. The manufacturer must keep records of 
all items listed in this section for at least 5 years from the date of 
termination of approval of each lifeboat. The records must include--

[[Page 228]]

    (11) The original purchaser of each lifeboat and the vessel on which 
it was installed, if known.
    (d) Independent laboratory responsibility. The independent 
laboratory must perform or witness, as appropriate, the inspections and 
tests under paragraph (e) of this section for each Coast Guard-approved 
lifeboat to be installed on a U.S.-flagged vessel. If the manufacturer 
also produces lifeboats for approval by other maritime safety 
administrations, the inspections may be coordinated with inspection 
visits for those administrations.
    (e) Production inspections and tests. Each approved lifeboat must be 
inspected and tested in accordance with each of the following 
procedures:
    (1) In-process inspections and tests. Each production lifeboat must 
be examined during lay-up of the hull to verify that the lay-up conforms 
to the approved drawings. Each FRP major component, such as the hull, 
canopy, and inner liner, must be examined and weighed after it is 
completed but before assembled. If the lifeboat is constructed by the 
spray lay-up technique, the hull and canopy thicknesses must be measured 
using ultrasonic or equivalent techniques. Laboratory tests of laminates 
must be conducted at this time. Test samples must be cut out from the 
lifeboat itself or be laid up at the same time, using the same 
procedures and by the same operators as the laminate used in the 
lifeboat. The number of samples used for each test, and the conditions 
and test methods used, must be as described in the applicable test 
specified in this paragraph.
    (i) Weight. The weight of each FRP section, such as hull, canopy, 
and inner liner, must be within 10 percent of similar sections of the 
prototype lifeboat. These weights must be the bare laminate weights. 
Backing plates that are molded into the laminate may be included.
    (ii) Thickness. The average thickness of each section of sprayed-up 
laminate must be within 20 percent of the corresponding sections of the 
prototype.
    (iii) Resin content. Laminate samples from the hull, canopy, and 
inner liners must be tested in accordance with ASTM D 2584 or ISO 1172 
(incorporated by reference, see Sec.  160.135-5 of this subpart). The 
resin content must be within 8 percentage points of the prototype 
results. If the resin content does not comply, flexural ultimate 
strength and tensile tests in paragraph (e)(1)(iv) of this section must 
be conducted.
    (iv) Flexural ultimate strength and tensile tests. Each laminate 
sample from each major component, such as hull and liner, that does not 
comply with the resin content requirement in paragraph (e)(1)(iii) of 
this section, and from each component of every fifth production 
lifeboat, must be subjected to the flexural ultimate strength and 
tensile strength tests as described in Sec.  160.135-11(c)(2)(i)(B) of 
this subpart. The values must be at least 90 percent of the prototype 
results.
    (v) Buoyancy material. If block foam buoyancy material is used, each 
piece must be weighed after it is cut and shaped to make sure that the 
correct amount of foam is installed. If foamed-in-place buoyancy 
material is used, a separate sample of the foam must be poured, and used 
to make a density determination after it has set. The density must be 32 
8 kg/m\3\ (2 0.5 lb/ft \3\).
    (vi) Steel sheet and plate. Steel sheet and plate for the hull, 
floors, and other structural components must meet ASTM A 36 and ASTM A

    To satisfy the requirements of the indicated regulations of SOLAS 
and IMO LSA Code, as amended by Resolution MSC.293(87) (incorporated by 
reference, see Sec.  160.151-5 of this subpart), each SOLAS A and SOLAS 
B inflatable liferaft must be manufactured in accordance with Sec. Sec.  
160.151-7 and 160.151-15, and must comply with the following additional 
requirements:
    (a) Stability (the IMO LSA Code, as amended by Resolution 
MSC.293(87), Chapter IV/4.2.5). (1) Each liferaft with a capacity of 
more than 8 persons must have a waterplane of circular or elliptical 
shape. A hexagonal, octagonal, or similar outline approximating a 
circular or elliptical shape is acceptable.
    (2) Each liferaft manufactured under this subpart must have water-
containing stability appendages on its underside to resist capsizing 
from wind and waves. These appendages must meet the following 
requirements:
    (i) The total volume of the appendages must not be less than 220 
liters (7.77 ft\3\) for liferafts approved to accommodate up to 10 
persons. The volume of an appendage is calculated using the bottom of 
the lowest opening in an appendage as the height of the appendage, and 
by deducting the volume of any objects inside the appendage. No opening 
designed to close as water is forced out of an appendage is an opening 
for the purpose of this calculation.
    (ii) The total volume of the appendages for liferafts approved to 
accommodate more than 10 persons must be not less than 20 x N liters 
(0.706 x N ft\3\), where N = the number of persons for which the 
liferaft is approved.
    (iii) The appendages must be securely attached and evenly 
distributed around the periphery of the exterior bottom of the liferaft. 
They may be omitted at the locations of inflation cylinders.
    (iv) The appendages must consist of at least two separate parts so 
that damage to one part will permit at least half of the required total 
volume to remain intact.
    (v) Openings in or between the appendages must be provided to limit 
the formation of air pockets under the inflatable liferaft.
    (vi) The appendages must be designed to deploy underwater when the 
liferaft inflates, and to fill to at least 60 percent of their capacity 
within 25 seconds of deployment. If weights are used for this purpose, 
they must be of corrosion-resistant material.
    (vii) The primary color of the appendages must be vivid reddish 
orange (color number 12197 of FED-STD-595C (incorporated by reference, 
see Sec.  160.151-5 of this subpart)), or a fluorescent color of a 
similar hue.
    (b) Boarding ramp (IMO LSA Code, as amended by Resolution 
MSC.293(87), Chapter IV/4.2.4.1). The boarding ramp must have sufficient 
size and buoyancy to support one person weighing 100 kg

this part or in 47 CFR part 80 must comply with those standards.



Sec.  160.151-27  Approval inspections and tests for inflatable liferafts.

    (a) Except as provided in paragraph (b) of this section, to satisfy 
the testing requirements of: IMO Revised recommendation on testing, as 
amended by Resolution MSC.295(87), part 1, paragraphs 5.1 through 5.15; 
paragraph 5.16 for a davit-launched inflatable liferaft; and paragraph 
5.17, a prototype inflatable liferaft of each design submitted for Coast 
Guard approval must meet the additional specific requirements and tests 
specified in paragraphs (c) and (d) of this section.
    (b) The Commandant may waive certain tests for a liferaft identical 
in construction to a liferaft that has successfully completed the tests, 
if the liferafts differ only in size and are of essentially the same 
design.
    (c) Tests must be conducted in accordance with the indicated 
paragraphs of IMO Revised recommendation on testing, as amended by 
Resolution MSC.295(87), except:
    (1) Jump test (Paragraph 1/5.2). One-half of the jumps must be with 
the canopy erect, and the remainder with the canopy furled or deflated. 
If a ``suitable and equivalent mass'' is used, it must be equipped with 
the shoes described in paragraph 1/5.2.1 of Resolution A.689(17), and 
arranged so the shoes strike the liferaft first.
    (2) Mooring-out test (Paragraph 1/5.5). Initial inflation may be 
with compressed air.
    (3) Loading and seating test (Paragraph 1/5.7). For a liferaft not 
intended for use with a launching or embarkation appliance, the persons 
used to determine seating capacity shall wear insulated buoyant 
immersion suits rather than lifejackets.
    (4) Boarding test (Paragraph 1/5.8). This test must be performed 
using each boarding ramp or boarding ladder which is installed on the 
liferaft.
    (5) Canopy-closure test (Paragraph 1/5.12). This test is required 
only for SOLAS A and SOLAS B inflatable liferafts. For a davit-launched 
liferaft, any opening near the lifting eye should be sealed during the 
test to prevent the ingress of water. The water accumulated within the 
liferaft at the end of the test must not exceed 4 L (1 gallon).
    (6) Detailed inspection (Paragraph 1/5.14). The independent 
laboratory's inspection of the prototype liferaft under Sec.  160.151-
13(a) satisfies the requirements of paragraph 1/5.14.
    (7) Davit-launched liferafts--strength test (Paragraph 1/5.16.1). 
The calculation of combined strength of the lifting components must be 
based on the lesser of--
    (i) The lowest breaking strength obtained for each item; or
    (ii) The component manufacturer's ultimate strength rating.
    (d) The boarding ramp on each liferaft equipped with one must be 
demonstrated capable of supporting one person weighing 100 kg (220 lb), 
sitting or kneeling and not holding onto any other part of the liferaft.

Sec.  160.151-31  Production inspections and tests of inflatable liferafts.

    (a) Production inspections and tests of inflatable liferafts must be 
carried out in accordance with the procedures for independent laboratory 
inspection in 46 CFR part 159, subpart 159.007, and with those of this 
section.
    (b) Each liferaft approved by the Coast Guard must be identified 
with unique lot and serial numbers as follows:
    (1) Each lot must consist of not more than 50 liferafts of the same 
design and carrying capacity.
    (2) A new lot must begin whenever the liferafts undergo changes of 
design, material, production method, or source of supply for any 
essential component.
    (3) The manufacturer may use a running-lot system, whereby the 
fabrication of the individual liferafts of a lot occurs over an extended 
interval under an irregular schedule. Each running lot must comprise not 
more than 10 liferafts of the same design and carrying capacity. Each 
running-lot system must be in accordance with a procedure proposed by 
the manufacturer and approved by the Commandant.
    (4) Unless a lot is a running lot, each lot must consist of 
liferafts produced under a process of continuous production.
    (c) Among the records required to be retained by the manufacturer 
under 46 CFR 159.007-13 , are affidavits or invoices from the suppliers 
identifying all essential materials used in the production of approved 
liferafts, together with the lot numbers of the liferafts constructed 
with those materials.
    (d) Each approved liferaft must pass each of the inspections and 
tests described in IMO Revised recommendation on testing, as amended by 
Resolution MSC.295(87), part 2, paragraphs 5.1.3 through 5.1.6 
inclusive, (incorporated by reference, see Sec.  160.151-5 of this 
subpart) and prescribed by paragraphs (e) through (g) of this section. 
For a davit-launched liferaft, these tests must be preceded by the test 
described in IMO Revised recommendation on testing, as amended by 
Resolution MSC.295(87), part 2, paragraph 5.2.
    (e) The test described in IMO Revised recommendation on testing, as 
amended by Resolution MSC.295(87), Paragraph 2/5.1.5, must be conducted 
under the following conditions:
    (1) The test must last 1 hour, with a maximum allowable pressure 
drop of 5 percent after compensation for changes in ambient temperature 
and barometric pressure.
    (2) For each degree Celsius of rise in temperature, 0.385 kPa must 
be subtracted from the final pressure reading (0.031 psig per degree 
Fahrenheit). For each degree Celsius of drop in temperature, 0.385 kPa 
must be added to the final pressure reading (again, 0.031 psig per 
degree Fahrenheit).

[[Page 240]]

    (3) For each mm of mercury of rise in barometric pressure, 0.133 kPa 
must be added to the final temperature-corrected pressure reading (0.049 
psig per 0.1 inch of mercury). For each mm of mercury of drop in 
barometric pressure, 0.133 kPa must be subtracted from the final 
temperature-corrected pressure reading (again, 0.049 psig per 0.1 inch 
of mercury). Corrections for changes in ambient barometric pressure are 
necessary only if a measuring instrument open to the atmosphere, such as 
a manometer, is used.
    (f) One liferaft from each lot of fewer than 30 liferafts, and two 
from each lot of 30 to 50 liferafts, must pass the test described in IMO 
Revised recommendation on testing, as amended by Resolution MSC.295(87), 
part 2, paragraphs 5.1.1 and 5.1.2. If any liferaft fails this test--
    (1) The reason for the failure must be determined;
    (2) Each liferaft in the lot must be examined for the defect and 
repaired if reparable, or scrapped if irreparable; and
    (3) The lot test must be repeated, including random selection of the 
liferaft or liferafts to be tested. If any liferafts from the lot have 
left the place of manufacture, they must be recalled for examination, 
repair, and testing as necessary; or else the required actions must take 
place at an approved servicing facility.
    (g) The manufacturer shall arrange for inspections by an accepted 
independent laboratory at least once in each calendar quarter in which 
production of liferafts approved by the Coast Guard takes place. The 
time and date of each inspection must be selected by the independent 
laboratory, to occur when completed liferafts are in the manufacturing 
facility and others are under construction. The manufacturer shall

facility with copies to the OCMI and to the manufacturer(s) whose 
liferafts the facility is approved to service. The letter will specify 
any limits on the approval, and will assign the facility's approval code 
for use on the inspection sticker required by Sec.  160.151-57(m)(3). 
The Commandant will maintain a current list of approved facilities.



Sec.  160.151-53  Notice to OCMI of servicing.

    (a) Before servicing an inflatable liferaft under the servicing 
facility's Coast Guard approval, the owner or operator of the facility 
must tell the cognizant OCMI for each liferaft to be serviced--
    (1) The make and size of the liferaft;
    (2) The age of the liferaft; and
    (3) Whether the liferaft is due for a five-year inflation test.
    (b) The OCMI will inform the servicing facility whether the 
servicing of

[[Page 245]]

the liferaft must be witnessed by an inspector.
    (c) If the OCMI requires the servicing of the liferaft to be 
witnessed by an inspector--
    (1) The servicing facility must arrange a schedule with the OCMI 
that will allow a Coast Guard inspector to travel to the site where the 
servicing is to occur;
    (2) The owner or operator of the servicing facility, by permission 
of the OCMI, may arrange for the servicing to be witnessed instead by a 
third-party inspector accepted by the OCMI if a Coast Guard marine 
inspector is not available in a timely manner; and
    (3) The servicing facility must not begin servicing the liferaft 
until the inspector arrives at the site.
    (d) No deviation from servicing-manual procedures may occur without 
the prior approval of the OCMI. To request the approval of a deviation, 
the owner or operator of the servicing facility shall notify the OCMI of 
the proposed deviation from the procedures, and must explain to the OCMI 
the need for the deviation.



Sec.  160.151-55  Withdrawal of approval.

    (a) The OCMI may withdraw the approval of the servicing facility, or 
may suspend its approval pending correction of deficiencies, if the 
Coast Guard inspector or accepted third-party inspector finds that--
    (1) The facility does not meet the requirements of Sec. Sec.  
160.151-41 through 160.151-47, or
    (2) The servicing is not performed in accordance with Sec.  160.151-
57.
    (b) A withdrawal of approval may be appealed in accordance with part 
1, subpart 1.03, of this chapter.
    (c) The OCMI may remove a suspension pending correction of 
deficiencies if the servicing facility demonstrates that the 
deficiencies have been corrected.



Sec.  160.151-57  Servicing procedure.

    (a) Each inflatable liferaft serviced by a servicing facility 
approved by the Coast Guard must be inspected and tested in accordance 
with paragraphs (b) through (r) of this section, and the manufacturer's 
servicing manual approved in accordance with Sec.  160.151-35(b)(1).
    (b) The following procedures must be carried out at each servicing:
    (1) The working-pressure leakage test described in IMO Revised 
recommendation on testing, as amended by Resolution MSC.295(87), 
paragraph 2/5.1.5 (incorporated by reference, see Sec.  160.151-5 of 
this subpart), must be conducted.
    (2) Inflation hoses must be pressurized and checked for damage and 
leakage as part of the working-pressure leakage test, or in a separate 
test.
    (3) An inflatable floor must be inflated until it is firm, and let 
stand for one hour. The inflatable floor must still be firm at the end 
of the hour.
    (4) The seams connecting the floor to the buoyancy tube must be 
checked for slippage, rupture, and lifting of edges.
    (5) Each item of survival equipment must be examined, and--
    (i) Replaced at the time of servicing if there is less than 6 months 
remaining before the expiration date; and
    (ii) Otherwise, repaired or replaced if it is damaged or 
unserviceable.
    (6) Each battery must be replaced with a fresh one if--
    (i) Its expiration date has passed;
    (ii) It has no expiration date; or
    (iii) It is to return to service in an item of survival equipment, 
but its measured voltage is less than its rated voltage.
    (7) Each power cell for the top and inside canopy lights must be 
inspected and tested as prescribed in the servicing manual unless it is 
a battery serviced in accordance with paragraph (b)(6) of this section. 
Each cell that is tested and found satisfactory may be reinstalled. Each 
cell that is outdated, is not tested, or fails the test must be 
replaced.
    (8) If the liferaft is equipped with an Emergency Position-
Indicating Radio Beacon (EPIRB) or a Search and Rescue Transmitter 
(SART), the EPIRB or SART must be inspected and tested in accordance 
with the manufacturer's instructions. An EPIRB must be tested using the 
integrated test circuit and output indicator to determine whether it is 
operative. Each EPIRB or SART not operative must be repaired or 
replaced.

[[Page 246]]

    (9) The manual inflation-pump must be tested for proper operation.
    (10) Each damaged, faded, or incorrect instruction label or 
identification label on the liferaft or its container must be replaced.
    (11) Each liferaft must be examined to ensure that it is properly 
marked with retroreflective material. The arrangement of the 
retroreflective material must meet the requirements of IMO Revised 
recommendation on testing, as amended by Resolution MSC.295(87). Damaged 
or missing retroreflective material must be replaced with Type I 
material approved under 46 CFR part 164, subpart 164.018, as complying 
with SOLAS.
    (12) Each inflation cylinder must be weighed. If its weight loss 
exceeds five percent of the weight of the charge, it must be recharged.
    (c) When an inflation cylinder is recharged for any reason, the 
following inflation-head components must be renewed:
    (1) The poppet-pin assembly, if any.
    (2) Each plastic or elastomeric seal, and each other part that 
deteriorates with age.
    (d) Each recharged inflation cylinder must stand for at least two 
weeks and be checked for leakage by weighing before being installed in a 
liferaft. An alternative mechanical or chemical test for fast detection 
of leakage may be used if the servicing manual approved by the 
Commandant in accordance with Sec.  160.151-35(b)(1) provides for it.
    (e) Each inflation cylinder that requires a hydrostatic test under 
49 CFR 180.205 must be tested and marked in accordance with that 
section.
    (f) At every second servicing of a davit-launched liferaft, the 
launching-load test in paragraph 2/5.2 of IMO Revised recommendation on 
testing, as amended by Resolution MSC.295(87) must be conducted.
    (g) At every fifth annual servicing, before the conduct of the tests 
and inspections required in paragraphs (b) through (f) of this section, 
each liferaft must be removed from its container and, while still 
folded, inflated by the operation of its gas-inflation system.
    (h) Each liferaft showing minor leaks during the gas inflation test 
conducted in accordance with paragraph (g) of this section, may be 
repaired.
    (i) Each liferaft ten or more years past its date of manufacture 
must be condemned if it leaks extensively, or shows fabric damage other 
than minor porosity, during the gas inflation test conducted in 
accordance with paragraph (g) of this section.
    (j) After the gas inflation test conducted in accordance with 
paragraph (g) of this section, the liferaft may be evacuated and 
refilled with air for the tests in paragraphs (b) through (f) of this 
section.
    (k) At each annual servicing of a liferaft ten or more years past 
its date of manufacture during which the gas-inflation test in paragraph 
(g) of this section is not conducted, a ``Necessary Additional 
Pressure'' (NAP) test must be conducted. Before the tests and 
inspections required in paragraphs (b) through (f) of this section are 
conducted, the NAP test must be completed, using the following 
procedure:
    (1) Plug or otherwise disable the pressure-relief valves.
    (2) Gradually raise the pressure to the lesser of 2 times the design 
working pressure, or that specified in the manufacturer's servicing 
manual as sufficient to impose a tensile load on the tube fabric of 20 
percent of its minimum required tensile strength.
    (3) After 5 minutes, there should be no seam slippage, cracking, 
other defects, or pressure drop greater than 5 percent. If cracking in 
the buoyancy tubes is audible, accompanied by pressure loss, condemn the 
liferaft. If it is not, reduce the pressure in all buoyancy chambers 
simultaneously by enabling the pressure-relief valves.
    (l) At each annual servicing of a liferaft 10 or more years past its 
date of manufacture, the integrity of the seams connecting the floor to 
the buoyancy tube must be checked by the following procedure, or an 
equivalent procedure specified in the manufacturer's approved servicing 
manual:
    (1) With the buoyancy tube supported a sufficient distance above the 
floor of the servicing facility to maintain clearance during the test, a 
person weighing not less than 75 kg (165 lb) shall walk or crawl around 
the entire perimeter of the floor of the liferaft.

[[Page 247]]

    (2) The seams connecting the floor to the buoyancy tube must then be 
inspected for slippage, rupture, and lifting of edges.
    (m) The servicing facility must complete the following for each 
liferaft that passes these inspections and tests:
    (1) Permanently mark the liferaft on its outside canopy, or on a 
servicing-record panel on an interior portion of one of its buoyancy 
tubes near an entrance, with--
    (i) The date of the servicing;
    (ii) The identification and location of the servicing facility; and
    (iii) If applicable, an indication that the special fifth-year 
servicing was performed.
    (2) Permanently and legibly mark on the identification device 
provided in accordance with Sec.  160.151-17(c), or on the outside 
canopy of the liferaft, the name, if known, of the vessel on which the

Sec.  160.156-7  Design, construction and performance of rescue boats
and fast rescue boats.

    (a) To seek Coast Guard approval of a rescue boat, including a fast 
rescue boat, a manufacturer must comply with, and each rescue boat must 
meet, the requirements of the following:
    (1) IMO LSA Code chapter V (incorporated by reference, see Sec.  
160.156-5 of this subpart);
    (2) IMO Revised recommendation on testing, part 1/7 (incorporated by 
reference, see Sec.  160.156-5 of this subpart) applicable to the type 
of rescue boat;
    (3) 46 CFR part 159; and
    (4) This subpart.
    (b) Each rescue boat must meet the following requirements:
    (1) Design. (i) Each rescue boat must be designed to be operable by 
persons wearing immersion suits.
    (ii) Each rescue boat should be designed following standard human 
engineering practices described in ASTM F 1166 (incorporated by 
reference, see Sec.  160.156-5 of this subpart). Design limits should be 
based on a range from the fifth percentile female to the ninety-fifth 
percentile male values for critical body dimensions and functional 
capabilities as described in ASTM F 1166. The dimensions for a person 
wearing an immersion suit correspond to the arctic-clothed dimensions of 
ASTM F 1166.
    (2) Visibility from operator's station. (i) The operator's station 
must be designed such that the operator, when seated at the control 
station, has visibility 360 degrees around the rescue boat, with any 
areas obstructed by the rescue boat structure or its fittings visible by 
moving the operator's head and torso.
    (ii) The operator, while still being able to steer and control the 
speed of the rescue boat, must be able to see the water--
    (A) Over a 90 degree arc within 3 m (10 ft) of each side of the 
rescue boat;
    (B) Over a 30 degree arc within 1 m (3 ft, 3 in) of each side of the 
rescue boat; and
    (C) Within 0.5 m (1 ft, 8 in) of the entrances designated for 
recovering persons from the water.
    (iii) In order to see a person in the water during recovery or 
docking operations, a hatch must be provided in fully enclosed rescue 
boats so that the operator can stand with his or her head outside the 
rescue boat for increased visibility, provided the operator can still 
steer and control the speed of the rescue boat.
    (3) Construction. Each major rigid structural component of each 
rescue boat must be constructed of steel, aluminum, or Fiber Reinforced 
Plastic (FRP), or materials accepted by the Commandant as equivalent or 
superior.
    (i) General. Metals in contact with each other must be either 
galvanically compatible or insulated with suitable non-porous materials. 
Provisions must also be made to prevent loosening or tightening 
resulting from differences of thermal expansion, freezing, buckling of 
parts, galvanic corrosion, or other incompatibilities.
    (ii) Steel. Sheet steel and plate must be low carbon, commercial 
quality, either corrosion resistant or galvanized as per ASTM A 653, 
coating designation G90 (incorporated by reference, see Sec.  160.156-5 
of this subpart). Structural steel plates and shapes must be carbon 
steel as per ASTM A 36 (incorporated

[[Page 252]]

by reference, see Sec.  160.156-5 of this subpart), or an equivalent or 
superior steel accepted by the Commandant. All steel products, except 
corrosion resistant steel, must be galvanized to provide high quality 
zinc coatings suitable for the intended service life in a marine 
environment. Corrosion resistant steel must be a type 302 stainless 
steel per ASTM A 276, ASTM A 313, or ASTM A 314 (incorporated by 
reference, see Sec.  160.156-5 of this subpart) or another corrosion 
resistant stainless steel of equal or superior corrosion resistant 
characteristics.
    (iii) Aluminum. Aluminum and aluminum alloys must conform to ASTM B 
209 (incorporated by reference, see Sec.  160.156-5 of this subpart) and 
be high purity for good marine corrosion resistance, free of iron, and 
containing not more than 0.6 percent copper.
    (iv) Fiber Reinforced Plastic (FRP).
    (A) Resin. Any resin used for the hull, canopy, hatches, rigid 
covers, and enclosures for the engine, transmission, and engine 
accessories, must be fire retardant and accepted by the Commandant in 
accordance with 46 CFR part 164, subpart 164.120.
    (B) Glass reinforcement. Any glass reinforcement used must have good 
laminated wet strength retention and must meet the appropriate 
specification in this paragraph. Glass cloth must be a finished fabric 
woven from ``E'' electrical glass fiber yarns meeting ASTM D 4029-09 
commercial style designation 1564 (incorporated by reference, see Sec.  
160.156-5 of this subpart). Woven roving must conform to MIL-C-19663D 
(incorporated by reference, see Sec.  160.156-5 of this subpart). Other 
glass materials equivalent or superior in strength, design, wet out, and 
efficiency will be given consideration on specific request to the 
Commandant.
    (C) Laminate. All exposed surfaces of any finished laminate must 
present a smooth finish, and there must be no protruding surface fibers, 
open voids, pits, cracks, bubbles, or blisters. The laminate must be 
essentially free from resin-starved or overimpregnated areas, and no 
foreign matter must remain in the finished laminate. The entire laminate 
must be fully cured and free of tackiness, and must show no tendency to 
delaminate, peel, or craze in any overlay. The laminate must not be 
released from the mold until a Barcol hardness reading of not less than 
40-55 is obtained from at least 10 places on the non-gel coated surface, 
including all interior inner and outer hull surfaces and built-in 
lockers. The mechanical properties of the laminate must meet the 
requirements for a Grade 3 laminate as specified in Table I of MIL-P-
17549D(SH) (incorporated by reference, see Sec.  160.156-5 of this 
subpart). Other grades will be given consideration on specific request 
to the Commandant.
    (4) Welding. Welding must be performed by welders certified by the 
Commandant, a classification society recognized by the Commandant in 
accordance with 46 CFR 8.220, the U.S. Navy, or the national body where 
the rescue boat is constructed or the national body's designated 
recognized organization. Only electrodes intended for use with the 
material being welded may be used. All welds must be checked using

Sec.  160.156-11  Fabrication of prototype rescue boats and fast rescue
boats for approval.

    (a) If the manufacturer is notified that the information submitted 
in accordance with Sec.  160.156-9 of this subpart is satisfactory to 
the Commandant, the manufacturer may proceed with fabrication of the 
prototype rescue boat as set forth in this section.
    (b) Unless the Commandant directs otherwise, an independent 
laboratory must perform or witness, as appropriate, inspections, tests, 
and oversight required by this section. Prototype inspections and tests 
of a rescue boat must be carried out in accordance with the procedures 
for independent laboratory inspection in 46 CFR part 159, subpart 
159.007 and in this section, unless the Commandant authorizes 
alternative tests and inspections. The Commandant may prescribe 
additional prototype tests and inspections necessary to maintain quality 
control and to monitor compliance with the requirements of this subpart.
    (c) Fabrication of a rescue boat must proceed in the following 
sequence:
    (1) The manufacturer must arrange for an independent laboratory (or 
Coast Guard inspector if required under paragraph (b) of this section) 
to inspect, test, and oversee the rescue boat during its fabrication and 
prepare an inspection and test report meeting the requirements of 46 CFR 
159.005-11.
    (2) The independent laboratory must make such inspections as are 
necessary to determine that the prototype is constructed by the methods 
and with the materials specified in the plans reviewed under Sec.  
160.156-9 of this subpart. By conducting at least one inspection during 
its construction, the independent laboratory must determine the 
prototype rescue boat conforms with those plans by inspecting--
    (i) Fiber Reinforced Plastic (FRP) Construction. (A) FRP components 
of each prototype rescue boat outer hull and any FRP inner hull or liner 
components that are bonded or bolted to the outer hull must have a layup 
made of unpigmented clear resins so that details of construction are 
visible for inspection. Test panels representative of each prototype 
layup must be tested in accordance with MIL-P-17549D(SH) (incorporated 
by reference, see Sec.  160.156-5 of this subpart). If an accepted MIL-
R-21607E(SH) Grade B resin is used for the prototype rescue boat, 
additives for fire retardancy must not be used so that the laminate is 
translucent for inspection purposes. A prototype test rescue boat with 
Grade B resins will not be marked in accordance with Sec.  160.156-17 of 
this subpart for use as a production rescue boat regardless of the 
outcome of the performance tests. Whichever accepted resin the 
manufacturer decides to use for the prototype rescue boat, the same 
resin must be used in the production rescue boats.
    (B) The hull, canopy, and major structural laminates of each 
prototype FRP rescue boat must be tested for resin content, ultimate 
flexural strength, and tensile strength. The test samples must be cut 
out from the prototype rescue boat, or be laid up at the same time, 
using the same procedures and by the same operators as the laminate used 
in the rescue boat. The number of samples used for each test, and the 
conditions and test methods used, must be as per the applicable test 
specified in this paragraph. The resin content must be determined as per 
ASTM D 2584 or ISO 1172 (incorporated by reference, see Sec.  160.156-5 
of this subpart). The flexural ultimate strength must be determined by 
ASTM D 790 method I (test condition ``A'', flatwise, dry) or the 
corresponding ISO 14125 test method (incorporated by reference, see 
Sec.  160.156-5 of this subpart). The tensile strength, lengthwise, must 
be determined as per ASTM D 638 or ISO 527 (incorporated by reference, 
see Sec.  160.156-5 of this subpart).
    (C) Each major FRP component, such as the hull, canopy, and inner 
liner(s) of each prototype FRP rescue boat, must be examined and weighed 
after it is completed but before it is assembled. If the rescue boat is 
constructed by the spray lay-up technique, the hull and canopy 
thicknesses must be measured using ultrasonic or equivalent techniques;
    (ii) Steel construction. Steel sheet and plate used for the hull, 
floors, and other structural components of a prototype steel rescue boat 
must meet the bend tests requirement specified under ASTM A 653 
(incorporated by reference,

[[Page 258]]

see Sec.  160.156-5 of this subpart) after galvanizing or other anti-
corrosion treatment has been applied. This may be demonstrated through 
supplier's certification papers or through witnessing actual tests;
    (iii) Welding. Structural components of each prototype rescue boat 
joined by welding must be joined by the welding procedures and materials 
per the plans reviewed under Sec.  160.156-9 of this subpart and by 
welders appropriately qualified;
    (iv) Buoyancy material. If block foam buoyancy material is used, 
each piece must be weighed after it is cut and shaped to make sure that 
the correct amount of foam is installed. If foamed-in-place buoyancy 
material is used, a separate sample of the foam must be poured, and used 
to make a density determination after it has set. The density must be 32 
8 kg/m\3\ (2 0.5 lb/ft\3\). 
Each major subassembly such as the hull-with-liner and canopy-with-liner 
must be weighed after the buoyancy foam is installed and before it is 
further assembled;
    (v) Coated fabric. Coated fabric for inflatable collars used in the 
construction of each rescue boat must meet the requirements specified 
under Sec.  160.156-7(b)(3) of this subpart. This may be demonstrated 
through a supplier's certification papers or through witnessing actual 
tests;
    (vi) Installation of the propulsion system; and
    (vii) Installation of the steering system.
    (3) The independent laboratory must submit the inspection report to 
the Commandant.



Sec.  160.156-13  Approval inspections and tests for prototype rescue
boats and fast rescue boats.

    (a) After the Commandant notifies the manufacturer that the 
prototype rescue boat is in compliance with the requirements of Sec.  
160.156-11 of this subpart, the manufacturer may proceed with the 
prototype approval inspections and tests required under this section. 
The prototype rescue boat, the construction of which was witnessed under 
Sec.  160.135-11 of this part, must be used for the tests in this 
section.
    (b) Except as provided in paragraph (f) of this section, the Coast 
Guard must conduct the approval inspections and witness the approval 
tests required under this section.
    (c) Manufacturer requirements. To proceed with approval inspections 
and tests required by this section, the manufacturer must--
    (1) Notify the Commandant and cognizant Officer in Charge, Marine 
Inspection (OCMI) of where the approval inspections and tests required 
under this section will take place, and such notification must be in 
sufficient time to allow making travel arrangements;
    (2) Arrange a testing schedule that allows for a Coast Guard 
inspector to travel to the site where the testing is to be performed;
    (3) Admit the Coast Guard inspector to any place where work or 
testing is performed on rescue boats or their component parts and 
materials for the purpose of--
    (i) Conducting inspections as necessary to determine that the 
prototype is constructed by the methods and with the materials specified 
in the plans reviewed under Sec.  160.156-9, and the inspection report 
under Sec.  160.156-11, of this subpart;
    (ii) Assuring that the quality assurance program of the manufacturer 
is satisfactory;
    (iii) Witnessing tests; and
    (iv) Taking samples of parts or materials for additional inspections 
or tests; and
    (4) Make available to the Coast Guard inspector the affidavits or 
invoices from the suppliers of all essential materials used in the 
production of rescue boats, together with records identifying the lot or 
serial numbers of the rescue boats in which such materials were used.
    (d) Tests. (1) Prototype rescue boat readiness. All tests must be 
conducted on a completely outfitted rescue boat, including fixed 
equipment such as a compass, searchlight, and navigating lights. Loose 
equipment may be substituted by weights.
    (2) FRP prototype rescue boat lay-up. For the prototype of each 
design of an FRP rescue boat, the lay-up must be made of unpigmented 
resins and clear gel coat.

[[Page 259]]

    (3) Fuel tank. Each non-portable fuel tank must be tested by a 
static head above the tank top of 3 m (10 ft) of water without showing 
any leaks or signs of permanent distortion.
    (4) IMO Revised recommendation on testing. Each prototype rescue 
boat of each design must pass each of the tests for the applicable hull 
type described in the IMO Revised recommendation on testing, part 1, 
section 7 (incorporated by reference, see Sec.  160.156-5 of this 
subpart). Tests must be conducted in accordance with these paragraphs of 
IMO Revised recommendation on testing, Part 1, with the following 
modifications:
    (i) Fire retardancy/release mechanism and engine tests (Paragraphs 
1/6.2, 6.9, 6.10, 6.14). The tests in the following IMO Revised 
recommendation on testing paragraphs may be accomplished independent of 
the rescue boat, and may be considered completed and need not be 
repeated if the tests have been previously shown to meet the following 
necessary requirements--
    (A) Paragraphs 6.9.3 through 6.9.6;
    (B) Paragraphs 6.10.2 through 6.10.6; and
    (C) Paragraphs 6.14.6 through 6.14.8.
    (ii) Impact test (Paragraph 1/6.4). The rigid vertical surface must 
not be displaced or deformed as a result of the test.
    (iii) Flooded stability test for rigid rescue boats only (Paragraph 
1/6.8). Any materials used to raise the test weights representing the 
rescue boat occupants above the seat pan must be at least as dense as 
fresh water.
    (iv) Rescue boat operational test, operation of engine (Paragraph 1/
7.1.5). For the 4-hour rescue boat maneuvering period, the rescue boat 
must not (except for a short period to measure towing force and to 
demonstrate towing fixture durability) be secured, and must be run 
through its full range of speeds and full range of all controls 
throughout the period.
    (v) Survival recovery test (Paragraph 1/6.10.8). The recovery 
demonstration must show that no more than two crewmembers are required 
to recover a helpless person of ninety-fifth percentile by weight 
described in ASTM F 1166 (incorporated by reference, see Sec.  160.156-5 
of this subpart) while the crewmembers and helpless person are each 
wearing a lifejacket.
    (vi) Rescue boat seating space test (Paragraph 1/7.1.3). The average 
mass of persons used to test the rescue boat seating space must be 
determined by weighing as a group or individually. Each person must wear 
an inherently buoyant SOLAS lifejacket with at least 150 N of buoyancy 
or a Coast Guard-approved lifejacket approved under approval series 
160.155. The operator(s) must demonstrate that the rescue boat can be 
operated while wearing a Coast Guard approved, insulated-buoyant 
immersion suit approved under approval series 160.171. The Commandant 
will give consideration to requests to test at, and designate rescue 
boats for, a heavier occupant weight than that stated in the IMO LSA 
Code, chapter V (incorporated by reference, Sec.  160.156-5 of this 
subpart).

    (d) Independent laboratory responsibility. The independent 
laboratory must perform or witness, as appropriate, the inspections and 
tests under paragraph (e) in this section for each Coast Guard-approved 
rescue boat to be installed on a U.S.-flagged vessel. If the 
manufacturer also produces rescue boats for approval by other maritime 
safety administrations, the inspections may be coordinated with 
inspection visits for those administrations.
    (e) Production inspections and tests. Each approved rescue boat must 
be inspected and tested in accordance with each of the following 
procedures:
    (1) In-process inspections and tests. Each production rescue boat 
must be examined during lay-up of the hull to verify that the lay-up 
conforms to the approved drawings. Each FRP major component, such as the 
hull, canopy, and inner liner, must be examined and weighed after it is 
completed but before assembled. If the rescue boat is constructed by the 
spray lay-up technique, the hull and canopy thicknesses must be measured 
using ultrasonic or equivalent techniques. Laboratory tests of laminates 
must be conducted at this time. Test samples must be cut out from the 
rescue boat itself or be laid up at the same time, using the same 
procedures, and by the same operators as the laminate used in the rescue 
boat. The number of samples used for each test, and the conditions and 
test methods used, must be as described in the applicable test specified 
in this paragraph.
    (i) Weight. The weight of each FRP section, such as hull, canopy, 
and inner liner, must be within 10 percent of similar sections of the 
prototype rescue boat. These weights must be the bare laminate weights. 
Backing plates that are molded into the laminate may be included.
    (ii) Thickness. The average thickness of each section of sprayed-up 
laminate must be within 20 percent of the corresponding sections of the 
prototype.
    (iii) Resin content. Laminate samples from the hull, canopy, and 
inner liners must be tested in accordance with ASTM D 2584 or ISO 1172 
(incorporated by reference, see Sec.  160.156-5 of this subpart). The 
resin content must be within 8 percentage points of the prototype 
results. If the resin content does not comply, flexural ultimate 
strength and tensile tests in paragraph (e)(1)(iv) of this section must 
be conducted.
    (iv) Flexural ultimate strength and tensile tests. Each laminate 
sample from each major component, such as hull and liner, that does not 
comply with the resin content requirement in paragraph (e)(1)(iii) of 
this section, and from each component of every fifth production rescue 
boat, must be subjected to the flexural ultimate strength and tensile 
strength tests as described in Sec.  160.156-11(c)(2)(i)(B) of this 
subpart. The values must be at least 90 percent of the prototype 
results.
    (v) Buoyancy material. If block foam buoyancy material is used, each 
piece must be weighed after it is cut and shaped to make sure that the 
correct amount of foam is installed. If foamed-in-place buoyancy 
material is used, a separate sample of the foam must be

[[Page 262]]

poured, and used to make a density determination after it has set. The 
density must be 32 8 kg/m\3\ (2 0.5 lb/ft\3\).
    (vi) Steel sheet and plate. Steel sheet and plate for the hull, 
floors, and other structural components must meet ASTM A 36 and ASTM A 
653 as applicable (incorporated by reference, see Sec.  160.156-5 of 
this subpart). Non-corrosive resistant steel must meet the coating mass 
and bend tests requirement specified under ASTM A 653. Compliance for 
this paragraph can be ascertained through supplier's certification 
papers or through conducting actual tests.
    (vii) Fabric. The coated fabric for inflatable collars, when used, 
for the construction of each rescue boat must meet ISO 15372 
(incorporated by reference, see Sec.  160.156-5 of this subpart). This 
compliance can be ascertained through a supplier's certification papers 
or through witnessing actual tests.
    (viii) Fuel tank. Each fuel tank must be tested by a static head 
above the tank top of 3 m (10 ft) of water without showing any leaks or 
signs of permanent distortion.
    (ix) Welding. It must be determined that structural components 
joined by welding was performed by welders who are appropriately 
qualified and that the welding procedure and materials are as per the 
plans approved under Sec.  160.156-13(h) of this subpart.
    (2) Post assembly tests and inspections. The finished rescue boat 
must be visually inspected inside and out. The manufacturer must develop 
and maintain a visual inspection checklist designed to ensure that all 
applicable requirements have been met and the rescue boat is equipped in 
accordance with approved plans. Each production rescue boat of each 
design must pass each of the tests described in the IMO Revised 
recommendation on testing, part 2, section 5.3 (incorporated by 
reference, see Sec.  160.156-5 of this subpart).

immersed in water at 5 [deg]C for a period of one hour. The glove may 
not be removable unless it is attached to the arm and unless it can be 
secured to the arm or stowed in a pocket on the arm when not in use. A 
removable glove must be designed so that there is no undue ingress of 
water into the glove during use. Each arm with a removable glove must 
have a wristlet seal that meets paragraph (e) of this section.
    (k) Leg construction. Each suit must be designed to minimize or 
reduce free air in its legs when the wearer enters the water headfirst.

[[Page 273]]

    (l) Foot construction. Each leg of a suit must have a foot that has 
a hard sole or enough room for a work shoe to be worn inside. The sole 
of each foot must be--
    (1) Natural or synthetic rubber that is ribbed or bossed for skid 
resistance; and
    (2) Designed to prevent the wearer from slipping when the suit is 
tested as prescribed in Sec.  160.171-17(c)(5).
    (m) Size. Each adult suit must fit persons ranging in weight from 50 
kg (110 lb.) to 150 kg (330 lb.) and in height from 1.5 m (59 in.) to 
1.9 m (75 in.). Each child size suit must fit children or small adults 
ranging in weight from 20 kg (44 lb.) to 50 kg (110 lb.) and in height 
from 1.0 m (39 in.) to 1.5 m (59 in.). An oversize adult suit is 
intended for persons too large for the standard adult suit. Each suit 
must be capable of being worn comfortably over clothing and must not 
restrict the wearer's motion. The suit size and design must allow 
successful completion of the mobility tests prescribed in Sec.  160.171-
17(c)(2) through (7).
    (n) Retroreflective material. Each immersion suit must be fitted 
with Type I retroreflective material that meets subpart 164.018 of this 
chapter. When the wearer of an immersion suit is in any stable floating 
position, at least 200 cm \2\ (31 sq. in.) of the material must be 
visible above water.
    (o) PFD Light. Each immersion suit must be designed so that a light 
meeting the requirements of subpart 161.012 of this chapter can be 
attached to its front shoulder area and so that the light when attached 
does not damage the suit and cannot adversely affect its performance. If 
the manufacturer of the suit designates a specific location for the 
light, or designates a specific model light, this information must be 
clearly printed on the suit or in the instructions prescribed by Sec.  
160.171-15(c).
    (p) Inflation tube. If the suit has an inflatable auxiliary means of 
buoyancy, each joint in the oral inflation tube must be joined with a 
clamping device. A flange connection between the tube and the inflatable 
chamber must be reinforced so that the flange on the inflation tube is 
secured between the material of the inflatable section and the 
reinforcement.

79 FR 58285, Sept. 29, 2014]



Sec.  160.171-11  Performance.

    (a) Buoyancy. Each suit must meet the following buoyancy 
requirements as measured in the test conducted under Sec.  160.171-
17(h):
    (1) The adjusted buoyancy of each adult and each oversize adult size 
suit must be at least 100 N (22 lb.). The adjusted buoyancy of each 
child size suit must be at least 50 N (11 lb.) The measured buoyancy 
must not be reduced by more than 5% after 24 hours submersion in fresh 
water.
    (2) Each suit must have a stable floating position in which the 
wearer's head must be tilted to a position between 30[deg] and 80[deg] 
above the horizontal, with the mouth and nose at least 120 mm (4\3/4\ 
in.) above the surface of the water. If necessary, this position may be 
obtained through the use of an auxiliary means of buoyancy such as an 
inflatable bladder behind the wearer's head.
    (3) If an auxiliary means of buoyancy is necessary to meet paragraph 
(a)(2) of this section, the suit must have a stable floating position 
without the auxiliary means of buoyancy in which the mouth and nose of 
the wearer are at least 50 mm (2 in.) above the surface of the water.
    (4) The buoyancy of any auxiliary means of buoyancy must not be 
counted when determining the buoyancy of the suit.
    (b) Righting. The suit must be designed to turn the body of an 
unconscious person in the water from any position to one where the mouth 
is clear of the water in not more than five seconds, without assistance 
or the use of any means of auxiliary buoyancy which must be inflated by 
the wearer; or to allow the wearer to turn from a face down to a face up 
position in not more than 5 seconds, without assistance or the use of 
any means of auxiliary buoyancy. If an automatically inflated means of 
auxiliary buoyancy is used to meet this paragraph, the inflation 
mechanism must meet the requirements for commercial hybrid

[[Page 274]]

PFDs in Sec.  160.077-15(c) of this chapter, and the tests required 
under Sec.  160.077-21(c)(3) of this chapter. Auxiliary buoyancy, if 
fitted and/or inflated, must not interfere with righting.
    (c) Thermal protection. The suit must be designed to protect against 
loss of body heat as follows:
    (1) The thermal conductivity of the suit material when submerged 1 m 
(39 in.) in water must be less than or equal to that of a control sample 
of 4.75 mm (\3/16\ in.) thick, closed-cell neoprene foam. The control 
sample of foam must have a thermal conductivity of not more than 0.055 
watt/meter-[deg] K (0.38 Btu-in./hr.-sq.ft.- [deg]F).
    (2) The suit must provide the wearer with sufficient thermal 
insulation, following one jump into the water from a height of 4.5 m, to 
ensure that the wearer's body core temperature does not fall more than 2 
[deg]C (3.6 [deg]F) after a period of 6 hours immersion in calm 
circulating water at a temperature of between 0 [deg]C (32 [deg]F) and 2 
[deg]C (35.6 [deg]F).
    (d) Donning time. Each suit must be designed so that a person can 
don the suit correctly within two minutes after reading the donning and 
use instructions described in Sec.  160.171-15(a).
    (e) Vision. Each suit must be designed to allow unrestricted vision 
throughout an arc of 60[deg] to either side of the wearer's straight-
ahead line of sight when the wearer's head is turned to any angle 
between 30[deg] to the right and 30[deg] to the left. Each suit must be 
designed to allow a standing wearer to move head and eyes up and down 
far enough to see both feet and a spot directly overhead.
    (f) Water penetration. An immersion suit must be designed to prevent 
undue ingress of water into the suit following a period of flotation in 
calm water of one hour.
    (g) Splash protection. Each suit must have a means to prevent water 
spray from directly entering the wearer's mouth.
    (h) Storage temperature. Each suit must be designed so that it will 
not be damaged by storage in its storage case at any temperature between 
-30 [deg]C (-22 [deg]F) and + 65 [deg]C (149 [deg]F).
    (i) Flame exposure. Each suit must be designed to prevent sustained 
burning or continued melting after it is totally enveloped in a fire for 
a period of 2 seconds.
    (j) Oil resistance. Each immersion suit must be designed to be 
useable after a 24 hour exposure to diesel oil.



Sec.  160.171-13  Storage case.

    (a) Each suit must have a storage case made of vinyl coated cloth or 
material that provides an equivalent measure of protection to the suit.
    (b) Each storage case must be designed so that it is still useable 
after two seconds contact with a gasoline fire.



Sec.  160.171-15  Instructions.

    (a) Each suit must have instructions for its donning and use in an 
emergency. The instructions must be in English and must not exceed 50 
words. Illustrations must be used in addition to the words. These 
instructions must be on the exterior of the storage case or printed on a 
waterproof card attached to the storage case or to the suit.
    (b) If the suit has an inflatable auxiliary means of buoyancy, 
separate instructions covering the use of the inflation valve must be 
provided on the suit near the valve or on a waterproof card attached 
near the valve.
    (c) Instructions for donning and use of the suit in an emergency 
must also be available in a format suitable for mounting on a bulkhead 
of a vessel. This placard must be in English, must include 
illustrations, and must include a warning as to the risk of entrapment 
in a submerged compartment due to the buoyancy of the suit.
    (d) Instructions for donning and use of the suit in an emergency, 
instructions for care and repair of the suit, and any additional 
necessary information concerning stowage and use of the suit on a vessel 
must be available in 8\1/2\ x 11 loose-leaf format suitable for 
inclusion in the vessel's training manual.



Sec.  160.171-17  Approval testing for adult size immersion suit.

    Caution: During each of the in-water tests prescribed in this 
section, a person ready to render assistance when needed should be near 
each subject in the water.

[[Page 275]]

    (a) General. An adult size immersion suit must be tested as 
prescribed in this section. If the suit is also made in a child size, a 
child size suit must be tested as prescribed in Sec.  160.171-19. If the 
suit is also made in an oversize adult size, an oversize adult suit must 
be tested as prescribed in Sec.  160.171-17(g) to determine the measured 
buoyancy for the suit. No additional testing will be required if the 
oversize adult suit is of the same design as the adult suit except for 
extra material to provide for larger persons.
    (b) Test samples. Each test prescribed in this section may be 
performed by using as many immersion suits as needed to make efficient 
use of the test subjects and test equipment, except that each subject in 
the impact test described in Sec.  160.171-17(c)(11) must not use more 
than one suit during the test, and the suits used in the impact test 
must also be used in the thermal protection test described in Sec.  
160.171-17(d).
    (c) Mobility and flotation tests. The mobility and flotation 
capabilities of each immersion suit must be tested under the following 
conditions and procedures:
    (1) Test subjects. Seven males and three females must be used in the 
tests described in this paragraph. The subjects must represent each of 
the three physical types (ectomorphic, endomorphic, and mesomorphic). 
Each subject must be in good health. The heaviest subject, of either 
sex, must weigh at least 135 kg (298 lb.). The heaviest male subject 
must weigh at least 115 kg (254 lb.) and the lightest male subject must 
weigh not more than 55 kg (121 lb). The heaviest female subject must 
weigh at least 115 kg (254 lb.) and the lightest female subject must 
weigh not more than 55 kg (121 lb). Each subject must be unfamiliar with 
the specific suit under test. Each subject must wear a standard range of 
clothing consisting of:
    (i) Underwear (short sleeved, short legged);
    (ii) Shirt (long sleeved);
    (iii) Trousers (not woolen);
    (iv) Woolen or equivalent synthetic socks;
    (v) Rubber soled work shoes.
    (2) Donning time. Each subject is removed from the view of the other 
subjects and allowed one minute to examine a suit and the manufacturer's 
instructions for donning and use of the suit in an emergency. At the end 
of this period, the subject attempts to don the suit as rapidly as 
possible without the aid of a chair or any support to lean on. If the 
subject does not don the suit completely, including gloves and any other 
accessories, within two minutes, the subject removes the suit and is 
given a demonstration of correct donning, and again attempts to don the 
suit. At least nine of the ten subjects must be able to don the suit 
completely, including time to remove shoes if necessary, in two minutes 
in at least one of the two attempts.
    (3) Field of vision. The immersion suit's field of vision must be 
tested as follows:
    (i) While wearing a suit, each subject sits upright and faces 
straight ahead. An observer is positioned to one side of the subject at 
an angle of 60[deg] away from the subject's straight-ahead line of 
sight. The observer must be able to see the subject's closest eye at 
this position. The observer then walks past the front of the subject to 
a position on the subject's other side that is at an angle of 60[deg] 
away from the subject's straight-ahead line of sight. The suit must not 
obstruct the observer's view of the subject's eyes at any point between 
the two positions.
    (ii) While wearing the suit, each subject stands upright and faces 
straight ahead. An observer is positioned to one side of the subject at 
an angle of 90[deg] away from the subject's straight-ahead line of 
sight. The subject then turns his or her head through an arc of 30[deg] 
toward the position of the observer. This procedure is repeated with the 
observer positioned on the other side of the subject at an angle of 
90[deg] away from the subject's straight ahead line of sight. The suit 
must not obstruct the observer's view of the subject's eyes when the 
subject's head is turned 30[deg] toward the observer.
    (iii) While wearing the suit, each subject stands upright and faces 
straight ahead. Through a combination of head and eye movement, the 
subject looks first at a spot directly overhead, then looks at a spot on 
or between the feet.

[[Page 276]]

An observer must verify that the subject can make the necessary head and 
eye movements while wearing the suit.
    (4) Hand dexterity. A physician must always be present during this 
test. While wearing a suit, including a removable glove if any, and 
after being immersed in water at 5 [deg]C (41 [deg]F) for a period of 
one hour, each subject must be able to pick up a 9.5 mm (\3/8\ in.) 
diameter wooden pencil from a flat hard surfaced table using only one 
hand. Still using only one hand, the subject must be able to position 
the pencil and write with it. At least eight of the ten test subjects 
must be able to complete this test. This test may be performed in 
conjunction with the thermal protection test described in Sec.  160.171-
17(d), in which case five of the six test subjects specified in Sec.  
160.171-17(d)(1) must be able to complete the test.
    (5) Walking. A 30 m (100 ft.) long walking course must be laid out 
on a smooth linoleum floor. The finish on the floor must allow water to 
lie on it in a sheet rather than in beads. The course may have gradual 
turns, but must not have any abrupt change in direction. Each subject is 
timed walking the course two times at a normal pace with the floor dry. 
Each subject then dons a suit and is timed again walking the course two 
times with the floor wet. The subject is given adequate rest between 
trials to avoid fatigue. The subject must not slip on the wet floor when 
wearing the suit. The average time for each subject to walk the course 
while wearing the suit must be not more than 1.25 times the subject's 
average time to walk the course without the suit.
    (6) Climbing. A vertical ladder extending at least 5 meters (17 
feet) above a level floor must be used for this test. Each subject is 
timed climbing the ladder twice to a rung at least 3 meters (10 feet) 
above the floor. The subject then dons a suit and is again timed 
climbing to the same rung twice. The subject is given adequate rest 
between trials to avoid fatigue. The average time for each subject to 
climb the ladder while wearing the suit must not be more than 1.25 times 
the subject's average time to climb the ladder without the suit.
    (7) Swimming and water emergence test. A pool with an inflatable 
liferaft at one side must be used for this test. The liferaft must be of 
a type approved under Subpart 160.051 of this Chapter and must not have 
a boarding ramp. Each subject, wearing a life preserver but not the 
immersion suit, enters the water and swims 25 m. The subject must then 
be able to emerge from the pool onto the liferaft using only the hands 
placed on top of the liferaft as an aid and without pushing off of the 
bottom of the pool. Any subject unable to emerge onto the liferaft 
within 30 seconds is disqualified for this test. At least five subjects 
must qualify and be used for this test. If less than five subjects of 
the original ten qualify, substitute subjects must be used. Each 
qualified subject, after sufficient rest to avoid fatigue, repeats this 
test wearing an immersion suit instead of the life preserver. At least 
two-thirds of the qualified subjects must be able to swim this distance, 
and emerge onto the liferaft within 30 seconds, wearing the immersion 
suit.
    (8) Stability and retroreflective material. While wearing the suit 
in water without any auxiliary means of buoyancy, each subject assumes a 
face-up position and then allows his or her body to become limp. The 
distance from the water surface to the lowest part of the subject's 
mouth or nose is measured. This procedure is repeated using the 
auxiliary means of buoyancy, if one is provided. For each test subject, 
the stable position and the distance of the mouth and nose above the 
water must be prescribed in Sec.  160.171-11(a)(2) and Sec.  160.171-
11(a)(3). During this test, each subject must be viewed by observers to 
determine whether the retroreflective material of the suit meets Sec.  
160.171-9(n).
    (9) Righting. Each subject while wearing a suit in water, without 
the use of any auxiliary means of buoyancy, takes a deep breath, assumes 
a face-down position, allows his or her body to become limp, and slowly 
expels air. The suit must cause the subject to turn to a position where 
the face is clear of the water within 5 seconds; or if the suit does not 
turn the subject within 5 seconds, the subject must be able to turn face 
up under his or her own power within 5 seconds. If the suit is

[[Page 277]]

provided with any means of auxiliary buoyancy, the procedure is repeated 
under each of the following applicable conditions:
    (i) With any means of auxiliary buoyancy attached but not inflated;
    (ii) With any means of auxiliary buoyancy which must be inflated by 
the wearer inflated according to the instructions; or
    (iii) With any means of auxiliary buoyancy which inflates 
automatically inflated by its automatic mechanism.
    (10) Water and air penetration. Each subject is weighed while 
wearing a pre-wetted suit without any auxiliary means of buoyancy. The 
subject jumps into water from a height that will cause the subject to be 
completely immersed. The subject swims or treads water for approximately 
one minute, emerges from the water, and is weighed within 10 seconds 
after emerging. The procedure is repeated with the subject entering the 
water headfirst. If air accumulates in the legs as the subject enters 
the water head-first, it must be expelled automatically. At the end of 
this test, the weight of the subject in the suit must not exceed the 
weight of the subject in the suit at the beginning of the test by more 
than 500 grams. Each test subject then re-enters the water and floats 
for a period of one hour. The subject then emerges from the water and is 
weighed within 10 seconds. The weight of the subject in the suit at the 
end of this test must not exceed the weight of the subject in the suit 
at the beginning of the period of flotation by more than 200 grams.
    (11) Impact. While wearing a suit without any auxiliary means of 
buoyancy, each subject jumps into water feet first six times from a 
height of 4.5 m (15 ft.) above the water surface. Each subject must be 
able to assume a face up stable position without assistance after each 
jump. The suit must not tear, separate at any seam, or exhibit any 
characteristic that could render it unsafe or unsuitable for use in 
water.
    (d) Thermal protection. The thermal protection capability of a suit 
must be tested under the following conditions and procedures;
    (1) Test subjects. Male subjects must be used for this test. Each 
subject must be familiarized with the test procedure before starting the 
test. Each subject must have somatotype parameters within the following 
ranges according to the Heath-Carter anthropometric method: endomorphy 
3.51.0; mesomorphy 4.01.5; 
ectomorphy 3.51.0.

    Note: The following publication, among others, contains guidance for 
use of the Heath-Carter anthropometric method: ``Body Type and 
Performance,'' Hebbelinck and Ross; FITNESS, HEALTH AND WORK CAPACITY, 
INTERNATIONAL STANDARDS FOR ASSESSMENT; Larson, L. A. (Ed.); 
International Committee for the Standardization of Physical Fitness 
Tests; Macmillan; New York; 1974 (pp. 266-283).


Each subject must have had a normal night's sleep before the test, a 
well-balanced meal 1 to 5 hours before the test, and no alcoholic 
beverages for 24 hours before the test. In addition to the suit, each 
subject must wear:
    (i) Underwear (short sleeved, short legged);
    (ii) Shirt (long sleeved);
    (ii) Trousers (not woolen);
    (iv) Woolen or equivalent synthetic socks;
    (v) Work shoes, if the suit is designed for shoes to be worn inside.
    (2) Test equipment. The test must be conducted in calm water with a 
temperature between 0 [deg]C (32 [deg]F) and 2 [deg]C (35.6 [deg]F). The 
air temperature 300 mm (1 ft.) above the water surface must be between 
minus 10 [deg]C (14 [deg]F) and 20 [deg]C (68 [deg]F). Each subject must 
be instrumented with an electrocardiograph, a thermistor or thermocouple 
in the rectum placed 150 mm (6 in) beyond the anus, thermistor or 
thermocouple in the lumbar region, a thermistor or thermocouple on the 
tip of the index finger, and a thermistor or thermocouple on the tip of 
the great toe. Each thermistor or thermocouple must have an accuracy of 
0.1 [deg]C (0.18 [deg]F). The suits used in this test must be the same 
ones previously subjected to the impact test described in Sec.  160.171-
17(c)(11).
    (3) Test procedure. A physician must always be present during this 
test. Before donning the suit, each subject rests quietly in a room with 
a temperature between 10 [deg]C (50 [deg]F) and 25 [deg]C (77 [deg]F) 
for 15 minutes. The rectal temperature is then recorded as the initial 
rectal temperature. The subject dons a suit as rapidly as possible 
without

[[Page 278]]

damaging the instrumentation and immediately enters the water. The 
subject assumes a face-up, stable floating position. No auxiliary means 
of buoyancy may be used during this test. The subject remains in the 
water engaging in activity that maintains the heart rate between 50 and 
140 per minute for the first hour, and between 50 and 120 per minute 
during the remainder of the test, except that no attempt is made to 
control heart rate if the subject is shivering. Each thermistor or 
thermocouple reading is recorded at least every 10 minutes.
    (4) Completion of testing. Testing of a subject ends six hours after 
he first enters the water, unless terminated sooner.
    (5) Termination of test. Testing of a subject must be terminated 
before completion if any of the following occurs:
    (i) The physician determines that the subject should not continue.
    (ii) The subject requests termination due to discomfort or illness.
    (iii) The subject's rectal temperature drops more than 2 [deg]C (3.6 
[deg]F) below the initial rectal temperature, unless the physician 
determines that the subject may continue.
    (iv) The subject's lumbar, finger, or toe temperature drops below 10 
[deg]C (50 [deg]F), unless the physician determines that the subject may 
continue.
    (6) Test results. The test results must be prepared as follows:
    (i) The total rectal temperature drop during the test period and the 
average lumbar, finger and toe temperature at the end of the test must 
be determined for each subject in the test, except subjects who did not 
complete testing for a reason stated in paragraph (d)(5)(i) or 
(d)(5)(ii) of this section. These temperatures and temperature drops 
must then be averaged. The average drop in rectal temperature must not 
be more than 2 [deg]C (3.6 [deg]F), and the average lumbar, toe and 
finger temperature must not be less than 5 [deg]C (41 [deg]F). Data from 
at least four subjects must be used in making these temperature 
calculations.
    (ii) Rates of toe, finger, lumbar, and rectal temperature drop for 
each subject who did not complete testing for a reason stated in 
paragraph (d)(5)(iii) or (d)(5)(iv) of this section must be determined 
using the highest temperature measured and the temperature measured 
immediately before testing was terminated. These rates must be used to 
extrapolate to 6 hours the estimated rectal, finger, lumbar, and toe 
temperature at the end of that time. These estimated temperatures must 
be the temperatures used in computing the average temperatures described 
in paragraph (d)(6)(i) of this section.
    (e) Insulation. Suit material must be tested under the following 
conditions and procedures, except that if the suit material meets the 
requirements for the control sample in paragraph (e)(1)(iii) of this 
section, the test procedure in paragraph (e)(2) of this section is not 
required.
    (1) Test equipment. The following equipment is required for this 
test:
    (i) A sealed copper or aluminum can that has at least two parallel 
flat surfaces and that contains at least two liters (two quarts) or 
water and no air. One possible configuration of the can shown in figure 
160.171-17(e)(1)(i).
    (ii) A thermistor or thermocouple that has an accuracy of 0.1 [deg]C (0.18 [deg]F) and that 
is arranged to measure the temperature of the water in the can.
    (iii) A control sample of two flat pieces of 4.75 mm (3/16 in.) 
thick, closed cell neoprene foam of sufficient size to enclose the can 
between them. The control sample must have a thermal conductivity of not 
more than 0.055 watt/meter-[deg] K (0.38 Btu-in./hr.-sq.ft.- [deg]F). 
The thermal conductivity of the control sample must be determined in 
accordance with the procedures in ASTM C 177 or ASTM C 518 (incorporated 
by reference, see Sec.  160.171-3).
    (iv) Two flat pieces of suit material of sufficient size to enclose 
the can between them. The surface covering, surface treatment, and 
number of layers of the material tested must be the same as those of 
material used in the suit. If the material used in the suit varies in 
thickness or number of layers, the material tested must be 
representative of the portion of the suit having the least thickness or 
number of layers.
    (v) A clamping arrangement to form a watertight seal around the 
edges of

[[Page 279]]

the material when the can is enclosed inside. A sealing compound may be 
used. Figure 160.171-17(e)(1)(v) shows one possible arrangement of the 
clamping arrangement.
    (vi) A container of water deep enough to hold the entire assembly of 
the can, material, and clamp at least 1 meter (39 in.) below the surface 
of the water.
    (vii) A means to control the temperature of the water in the 
container between 0 [deg]C (32 [deg]F) and 1 [deg]C (33.8 [deg]F).
    (viii) A thermistor or thermocouple that has an accuracy of 0.1 [deg]C (0.18 [deg]F) and that is arranged to measure 
the temperature of the water in the container at the depth at which the 
can, material, and clamp are held.
    (2) Test procedure. The can is held under water (which can be at 
room temperature) and clamped between the two pieces of the neoprene 
control sample so that the assembly formed conforms as closely as 
possible to the shape of the can, and so that water fills all void 
spaces between the can and the sample. When the water temperature in the 
can is at or above 45 [deg]C (113 [deg]F), the assembly is then placed 
in the container and submerged to a depth of 1 m (39 in.) at the highest 
point of the assembly. The water temperature in the container must be 
between 0 [deg]C (32 [deg]F) and 1 [deg]C (33.8 [deg]F) and must be 
maintained within this range for the remainder of the test. No part of 
the assembly may touch the bottom or sides of the container. Every two 
minutes the assembly is shaken and then inverted from its previous 
position. The time for the water inside the can to drop from 45 [deg]C 
(113 [deg]F) to 33 [deg]C (91 [deg]F) is recorded. This procedure is 
performed three times using the control sample and then repeated three 
times using the suit material instead of the control sample. The 
shortest time for the drop in water temperature when the suit material 
is used must be greater than or equal to the shortest time when the 
neoprene control sample is used.
    (f) Storage temperature. Two samples of the immersion suits, in 
their storage cases, must be alternately subjected to surrounding 
temperatures of -30 [deg]C to + 65 [deg]C. These alternating cycles need 
not follow immediately after each other and the following procedure, 
repeated for a total of ten cycles, is acceptable:
    (1) 8 hours conditioning at 65 [deg]C to be completed in one day;
    (2) The specimens removed from the warm chamber that same day and 
left exposed under ordinary room conditions until the next day;
    (3) 8 hours conditioning at -30 [deg]C to be completed the next day; 
and
    (4) The specimens removed from the cold chamber that same day and 
left exposed under ordinary room conditions until the next day. At the 
conclusion of the final cycle of cold storage, two test subjects who 
successfully completed the donning test in paragraph (c)(2) of this 
section enter the cold chamber, unpack and don the immersion suits. 
Alternatively, the suits may be unpacked in the chamber, then removed 
and immediately donned. Neither of the suits must show damage such as 
shrinking, cracking, swelling, dissolution or change of mechanical 
qualities.
    (g) Measured buoyancy. The buoyancy of a suit must be measured under 
the following conditions and procedures:
    (1) Test equipment. The following equipment is required for this 
test:
    (i) A mesh basket that is large enough to hold a folded suit, and 
that is weighted sufficiently to overcome the buoyancy of the suit when 
placed in the basket.
    (ii) A tank of water that is large enough to contain the basket 
submerged with its top edge 50 mm (2 in.) below the surface of the 
water.
    (iii) A scale or load cell that has an accuracy of 0.15 Newtons (1/2 
oz.) and that is arranged to support and weigh the basket in the tank.
    (2) Test procedure. The basket is submerged so that its top edge is 
50 mm (2 in.) below the surface of the water. The basket is then 
weighed. Thereafter, a suit is submerged in water and then filled with 
water, folded, and placed in the submerged basket. The basket is titled 
45[deg] from the vertical for five minutes in each of four different 
directions to allow all entrapped air to escape. The basket is then 
suspended with its top edge 50 mm (2 in.) below the surface of the water 
for 24 hours. At the beginning and end of this period, the basket and 
suit are weighed underwater. The

[[Page 280]]

measured buoyancy of the suit is the difference between this weight and 
the weight of the basket as determined at the beginning of the test. The 
measured buoyancy after 24 hours must not be more than 5% lower than the 
initial measured buoyancy. The measured buoyancy after 24 hours is used 
to determine adjusted buoyancy as described in paragraph (h) of this 
section.
    (h) Adjusted buoyancy. The adjusted buoyancy of a suit is its 
measured buoyancy reduced by the percentage buoyancy loss factor of the 
buoyant suit material. The percentage buoyancy loss factor is part of 
the buoyancy rating code determined in accordance with UL 1191, except 
that the minimum number of samples required to determine each property 
is 10 instead of 75.
    (i) Suit flame exposure. The suit's resistance to flame must be 
tested under the following conditions and procedures:
    (1) Test equipment. The following equipment is required for this 
test:
    (i) A metal pan that is at least 300 mm (12 in.) wide, 450 mm (18 
in.) long, and 60 mm (2\1/2\ in.) deep. The pan must have at least 12 mm 
(\1/2\ in.) of water on the bottom with approximately 40 mm (1\1/2\ in.) 
of gasoline floating on top of the water.
    (ii) An arrangement to hold the suit over the gasoline.
    (2) Test procedure. A suit is held from its top by the holding 
arrangement. The gasoline is ignited and allowed to burn for 
approximately 30 seconds in a draft-free location. The suit is then held 
with the lowest part of each foot 240 mm (9.5 in.) above the surface of 
the burning gasoline. After two seconds, measured from the moment the 
flame first contacts the suit, the suit is removed from the fire. The 
suit must not sustain burning or continue melting after removal from the 
flames. If the suit sustains any visible damage other than scorching, it 
must then be subjected to the stability test described in paragraph 
(c)(8) of this section, except that only one subject need be used; the 
impact test described in paragraph (c)(11) of this section, except that 
only one subject need be used; the thermal protection test described in 
paragraph (d) of this section, except that only one subject need be 
used; and the buoyancy test described in paragraph (g) of this section, 
except that the buoyancy test need be conducted for only 2 hours.
    (j) Storage case flame exposure. The storage case must be tested 
using the same equipment required for the suit flame exposure test. The 
immersion suit must be inside the storage case for this test. The 
storage case is held from its top by the holding arrangement. The 
gasoline is ignited and allowed to burn for approximately 30 seconds in 
a draft-free location. The storage case is then held with its lowest 
part 240 mm (9.5 in.) above the surface of the burning gasoline. After 
two seconds, measured from the moment the flames first contact the case, 
the case is removed from the fire. If the case is burning, it is allowed 
to continue to burn for six seconds before the flames are extinguished. 
The storage case material must not burn through at any point in this 
test and the immersion suit must not sustain any visible damage.
    (k) Corrosion resistance. Each metal part of a suit that is not 410 
stainless steel, or for which published evidence of salt-spray corrosion 
resistance equal to or greater than 410 stainless steel is not 
available, must be tested as described in ASTM B 117 (incorporated by 
reference, see Sec.  160.171-3). A sample of each metal under test and a 
sample of 410 stainless steel must be tested for 720 hours. At the 
conclusion of the test, each sample of test metal must show corrosion 
resistance equal to or better than the sample of 410 stainless steel.
    (l) Body strength. The body strength of a suit must be tested under 
the following conditions and procedures:
    (1) Test equipment. The test apparatus shown in figure 160.171-
17(1)(1) must be used for this test. This apparatus consists of--
    (i) Two rigid cylinders each 125 mm (5 in.) in diameter, with an eye 
or ring at each end;
    (ii) A weight of 135 kg (300 lb.); and
    (iii) Ropes or cables of sufficient length to allow the suit to be 
suspended as shown in Figure 160.171-17(1)(1).
    (2) Test procedure. The suit is cut at the waist and wrists, or 
holes are cut into it as necessary to accommodate

[[Page 281]]

the test apparatus. The suit is immersed in water for at least two 
minutes. The suit is then removed from the water and immediately 
arranged on the test apparatus, using each closure as it would be used 
by a person wearing the suit. The 135 kg (300 lb.) load is applied for 5 
minutes. No part of the suit may tear or break during this test. The 
suit must not be damaged in any way that would allow water to enter or 
that would affect the performance of the suit.
    (m) Seam strength. The strength of each different type of seam used 
in a suit must be tested under the following conditions and procedures:
    (1) Test equipment. The following equipment must be used for this 
test.
    (i) A chamber in which air temperature can be kept at 23 [deg]C 
(73.4 [deg]F) 2 [deg]C (1.8 [deg]F) and in which 
relative humidity can be kept at 50% 5%.
    (ii) A device to apply tension to the seam by the means of a pair of 
top jaws and a pair of bottom jaws. Each set of jaws must grip the 
material on both sides so that it does not slip when the load is 
applied.
    (2) Test samples. Each test sample must consist of two pieces of 
suit material, each of which is a 100 mm (4 in.) square. The two pieces 
are joined by a seam as shown in figure 160.171-17(m)(3). For each type 
of seam, 5 samples are required. Each sample may be cut from the suit or 
may be prepared specifically for this test. One type of seam is 
distinguished from another by the type and size of stitch or other 
joining method used and by the type and thickness of the materials 
joined at the seam.
    (3) Test procedure. Each sample is conditioned for at least 40 hours 
at 23 [deg]C (73.4 [deg]F) 2[deg](1.8 [deg]F) C 
and 50% 5% relative humidity. Immediately after 
conditioning, each sample is mounted individually in the tension device 
as shown in figure 160.171-17(m)(3). The jaws are separated at a rate of 
5 mm/second (12 in./minute). The force at rupture is recorded. The 
average force at rupture must be at least 225 Newtons (50 lb.).
    (n) Tear resistance. The tear resistance of suit material must be 
determined by the method described in ASTM D 1004. If more than one 
material is used, each material must be tested. If varying thickness of 
a material are used in the suit, samples representing the thinnest 
portion of the material must be tested. If multiple layers of a material 
are used in the suit, samples representing the layer on the exterior of 
the suit must be tested. Any material which is a composite formed of two 
or more materials bonded together is considered to be a single material. 
The average tearing strength of each material must be at least 45 
Newtons (10 lb.).
    (o) Abrasion resistance. The abrasion resistance of each type of 
suit material on the exterior of the suit must be determined by the 
method described in Federal Test Method Standard 191, Method 5304.1. If 
varying thicknesses of exterior suit material are used, samples 
representing the thinnest portion of the material must be tested. If 
exterior material has multiple layers, samples of the layer on the 
outside surface of the suit must be tested. Any exterior material which 
is a composite formed of two or more layers bonded together is 
considered to be a single material and the abradant must be applied to 
the surface that is on the exterior of the suit. The residual breaking 
strength of each material must be at least 225 Newtons (50 lb.).
    (p) Test for oil resistance. After all its apertures have been 
sealed, an immersion suit is immersed under a 100 mm head of diesel oil, 
grade No. 2-D as defined in ASTM D 975 (incorporated by reference, see 
Sec.  160.171-3) for 24 hours. The surface oil is then wiped off and the 
immersion suit subjected to the leak test prescribed in Sec.  160.171-
17(c)(10). The ingress of water must not be greater than 200 grams.

Sec.  160.171-19  Approval testing for child size immersion suit.

    A child size suit must pass the following tests:
    (a) The stability test prescribed in Sec.  160.171-17(c)(8), except 
that only six children need be used as test subjects and they can be of 
either sex. The subjects must be within the ranges of weight and height 
prescribed in Sec.  160.171-9(m). The heaviest subject

[[Page 282]]

must weigh at least 10 kg (22 lb.) more than the lightest subject. 
During this test the face seal, neck and chin fit are evaluated and must 
be comparable to the fit of the corresponding adult size suit on an 
adult.
    (b) The buoyancy test prescribed in Sec.  160.171-17(g).
    (c) The body strength test prescribed in Sec.  160.171-17(k) except 
that the cylinders must be 50 mm (2 in.) in diameter and the test weight 
must be 55 kg (120 lb.).



Sec.  160.171-23  Marking.

    (a) Each immersion suit must be marked with the words ``IMMERSION 
SUIT--COMPLIES WITH SOLAS 74/83,'' the name of the manufacturer, the 
date of manufacturer, the model, the size, and the Coast Guard approval 
number.
    (b) Each storage case must be marked with the words ``immersion 
suit'' and the size.
    (c) The markings for the child size immersion suits required under 
paragraphs (a) and (b) of this section must also include the following 
statements in print smaller than the word ``child'': ``(Small Adult 
Under 50 kg. (110 lb.))'', and ``Children Require Adult Assistance for 
Donning and Use.''
    (d) If an auxiliary means of buoyancy is removable and is needed to 
meet Sec.  160.171-11(a)(2), the marking on the suit must indicate that 
the suit is not Coast Guard approved unless the auxiliary means of 
buoyancy is attached.



Sec.  160.171-25  Production testing.

    (a) Immersion suit production testing is conducted under the 
procedures in this section and subpart 159.007 of this chapter.
    (b) One out of every 100 immersion suits produced must be tested as 
prescribed in Sec.  160.171-17(g) and must be given a complete visual 
examination. The suit must be selected at random from a production lot 
of 100 suits and tested by or under the supervision of the independent 
laboratory. A suit fails this test if--
    (1) The measured buoyancy of the suit differs by more than 10% from 
the measured buoyancy of the suit tested for approval,
    (2) The adjusted buoyancy of the suit calculated using the buoyancy 
loss factor determined during approval testing is less than that 
required in Sec.  160.171-11(a)(1), or
    (3) The visual examination shows that the suit does not conform to 
the approved design.
    (c) If the suit fails to pass the test as prescribed in paragraph 
(b)(1) or (b)(2) of this section, 10 additional suits from the same lot 
must be selected at random and subjected to the test. If a defect in the 
suit is detected upon visual examination, 10 additional suits from the 
same lot must be selected at random and examined for the defect.
    (d) If one or more of the 10 suits fails to pass the test or 
examination, each suit in the lot must be tested or examined for the 
defect for which the lot was rejected. Only suits that pass the test or 
that are free of defects may be sold as Coast Guard approved.
    (e) The manufacturer must ensure that the quality control procedure 
described in the test plans previously submitted for approval under 
Sec.  159.005-9(a)(5)(iii) is followed.

Sec.  160.174-11  Performance.

    (a) Thermal protection. The thermal protective aid must be designed 
to protect against loss of body heat as follows:
    (1) The thermal conductivity of the material from which the thermal 
protective aid is constructed must be not more than 0.25 W/(m-[deg]K).
    (2) The thermal protective aid must prevent evaporative heat loss.
    (3) The aid must function properly at an air temperature of -30 
[deg]C (-22 [deg]F) to + 20 [deg]C (68 [deg]F).
    (b) Donning Time. Each thermal protective aid must be designed to 
enable a person to don the aid correctly within one minute after reading 
the donning and use instructions described in Sec.  160.174-15(a).
    (c) Storage Temperature. A thermal protective aid must not be 
damaged by storage in its storage case at any temperature between -30 
[deg]C (-22 [deg]F) and + 65 C (149 [deg]F).
    (d) In water performance. The thermal protective aid must be 
designed to permit the wearer to remove it in the water within two 
minutes, if it impairs ability to swim.
    (e) Water penetration. The fabric from which the thermal protective 
aid is constructed must maintain its watertight integrity when 
supporting a column of water 2 meters high.
    (f) Oil resistance. Each thermal protective aid must be designed to 
be useable after 24 hours exposure to diesel oil.



Sec.  160.174-13  Storage case.

    Each thermal protective aid must be provided with a ziplock bag or 
equivalent storage case.



Sec.  160.174-15  Instructions.

    (a) Each thermal protective aid must have instructions for its 
donning and use in an emergency. The instructions must be in English and 
must not exceed 50 words. Illustrations must be used in addition to the 
words. The instructions must include advice as to whether to swim in the 
aid or discard it if the wearer is thrown into the water.
    (b) The instructions required by paragraph (a) of this section must 
be on the exterior of the storage case, printed on a waterproof card 
attached to the storage case, or printed on the thermal protective aid 
and visible through a transparent storage case. The instructions must 
also be available in 8\1/2\ x 11 inch loose-leaf format for inclusion in 
the vessel's training manual.



Sec.  160.174-17  Approval testing.

    (a) General. A thermal protective aid must be tested as prescribed 
in this section.
    (b) Mobility and swimming tests. The mobility and swimming 
capabilities of each thermal protective aid must be tested under the 
following conditions and procedures:
    (1) Test subjects. Seven males and three females must be used in the 
tests described in this paragraph. The subjects must represent each of 
the three physical types (ectomorphic, endomorphic, and mesomorphic). 
Each subject must be in good health. The heaviest male subject must 
weigh at least 25 kg (55 lb) more than the lightest male subject. The 
heaviest female subject must weigh at least 25 kg (55 lb) more than the 
lightest female subject. The heaviest subject must weigh 1505 Kg (33011 lbs.) and the lightest 
subject must weigh 505 Kg (11011 lbs.). Each subject must be unfamiliar with the

[[Page 288]]

specific thermal protective aid under test. Each subject must wear a 
standard range of clothing consisting of:
    (i) Underwear (short sleeved, short legged);
    (ii) Shirt (long sleeved);
    (iii) Trousers (not woolen);
    (iv) Woolen socks;
    (v) Rubber soled shoes; and
    (vi) A life preserver.
    (2) Donning test. Each subject is removed from the view of the other 
subjects and allowed one minute to examine the thermal protective aid 
and the manufacturer's instructions for donning and use of the aid in an 
emergency. At the end of this period, the subject attempts to don the 
thermal protective aid as rapidly as possible. If the subject does not 
don the thermal protective aid completely, including gloves and any 
other accessories, within 60 seconds, the subject removes the aid and is 
given a demonstration of correct donning, and again attempts to don the 
aid. At least nine out of ten subjects must be able to don the thermal 
protective aid completely in 60 seconds on at least one of the two 
attempts.
    (3) Discarding test. If the thermal protective aid impairs the 
ability of the wearer to swim, it must be demonstrated that it can be 
discarded by the test subjects, when immersed in water, in not more than 
two minutes. Caution: During each of the in water tests prescribed in 
this section, a person ready to render assistance when needed should be 
near each subject in the water.
    (i) Unless the manufacturer specifies in the instructions that the 
thermal protective aid does impair ability to swim and should always be 
discarded in the water, each subject, wearing a life preserver, enters 
the water and swims 25 meters. The subject, after sufficient rest to 
avoid fatigue, repeats this test wearing a thermal protective aid in 
addition to the life preserver. At least nine out of ten subjects must 
be able to swim this distance wearing the thermal protective aid in not 
more than 125% of the time taken to swim the distance wearing only a 
life preserver, or the aid will be determined to impair the ability to 
swim.
    (ii) If the thermal protective aid is determined by the above test 
or specified by the manufacturer to impair the ability to swim, each 
subject, after entering the water from a height of one meter (three 
feet), attempts to remove the aid and discard it. At least nine out of 
ten subjects must be able to discard the device within two minutes.
    (c) [Reserved]
    (d) Storage temperature. Two samples of the thermal protective aids, 
in their storage cases, are alternately subjected to surrounding 
temperatures of -30 [deg]C to + 65 [deg]C. These alternating cycles need 
not follow immediately after each other and the following procedure, 
repeated for a total of ten cycles, is acceptable:
    (1) 8 hours conditioning at 65 [deg]C to be completed in one day;
    (2) The specimens removed from the warm chamber that same day and 
left exposed under ordinary room conditions until the next day;
    (3) 8 hours conditioning at -30 [deg]C to be completed the next day; 
and
    (4) The specimens removed from the cold chamber that same day and 
left exposed under ordinary room conditions until the next day. At the 
conclusion of step (3) of the final cycle of cold storage, two test 
subjects who successfully completed the donning test previously enter 
the cold chamber, unpack and don the thermal protective aids. The aids 
must not show any damage, such as shrinking, cracking, swelling, 
dissolution or change of mechanical qualities.
    (e) Water penetration. A sample of the fabric from which the thermal 
protective aid is constructed is installed as a membrane at one end of a 
tube of at least 2.5 cm (one inch) diameter and 2 meters long. The tube 
is fixed in a vertical position with the membrane at the bottom, and 
filled with water. After one hour the membrane must continue to support 
the column of water with no leakage.
    (f) Insulation. The material from which the thermal protective aid 
is constructed is tested in accordance with the procedures in ASTM C 
177, ASTM C 518, or ASTM D 1518. The material must have a thermal 
conductivity of not more than 0.25 W/(m-[deg]K)

[[Page 289]]

(incorporated by reference, see Sec.  160.174-3).
    (g) Test for oil resistance. After all its apertures have been 
sealed, a thermal protective aid is immersed under a 100 mm head of 
diesel oil, grade no. 2-D as defined in ASTM D 975 (incorporated by 
reference, see Sec.  160.174-3), for 24 hours. The surface oil is then 
wiped off and a sample of the material from the aid is again tested in 
accordance with the procedures in ASTM C 177 or ASTM C 518 (incorporated 
by reference, see Sec.  160.174-3). The material must still have a 
thermal conductivity of not more than 0.25 W/(m-[deg] K).
    (h) Seam strength. The strength of each different type of seam used 
in a thermal protective aid must be tested under the following 
conditions and procedures.
    (1) Test equipment. The following equipment must be used in this 
test:
    (i) A chamber in which air temperature can be kept at 25 [deg]C 
(73.4 [deg]F) 2 [deg]C (1.8 [deg]F) and in which 
relative humidity can be kept at 50% 5%.
    (ii) A device to apply tension to the seam by means of a pair of top 
jaws and a pair of bottom jaws. Each set of jaws must grip the material 
on both sides so that it does not slip when the load is applied. Each 
front jaw must be 25 mm (1 inch) wide by 25 mm (1 inch) long. The 
distance between the jaws before the load is applied must be 75mm (3 
inches).
    (2) Test samples. Each test sample consists of two pieces of the 
material from which the thermal protective aid is constructed, each of 
which is 100 mm (4 inches) square. The two pieces are joined by a seam 
as shown in figure 160.171-17(m)(3). For each type of seam, 5 samples 
are required. Each sample may be cut from a thermal protective aid or 
may be prepared specifically for this test. One type of seam is 
distinguished from another by the type and size of stitch or other 
joining method used (including orientation of warp and fill, if any) and 
by the type and thickness of the materials joined at the seam.
    (3) Test procedure. Each sample is conditioned for at least 40 hours 
at 23 [deg]C2 [deg]C and 50% 5% relative humidity. Immediately after conditioning, 
each sample is mounted individually in the tension device as shown in 
figure 160.171-17(m)(3). The jaws are separated at a rate of 5 mm/second 
(12 in/minute). The maximum force to achieve rupture is recorded. The 
average force at rupture must be at least 225 Newtons (50 lb).
    (i) Tear resistance. The tear resistance of the material from which 
a thermal protective aid is constructed must be determined by the method 
described in ASTM D 1004 (incorporated by reference, see Sec.  160.174-
3). If more than one material is used, each material must be tested. If 
varying thicknesses of a material are used in the aid, samples 
representing the thinnest portion of the material must be tested. If 
multiple layers of a material are used in the aid, samples representing 
the layer on the exterior of the aid must be tested. Any material that 
is a composite formed of two or more materials bonded together is 
considered to be a single material. The average tearing strength of each 
material must be at least 45 Newtons (10 lb).

may be determined, and the Coast Guard approval number.
    (b) Each storage case must be marked with the words ``Thermal 
Protective Aid'' or the thermal protective aid must have a similar 
marking which is visible through a transparent storage case.



Sec.  160.174-25  Production testing.

    (a) Thermal protective aid production testing is conducted under the 
procedures in this section and subpart 159.007 of this chapter.
    (b) One out of every 100 thermal protective aids produced must be 
given a complete visual examination. The sample must be selected at 
random from a production lot of 100 thermal protective aids and examined 
by or under the

[[Page 290]]

supervision of the independent laboratory. The sample fails if the 
visual examination shows that the aid does not conform to the approved 
design.
    (c) If a defect in the thermal protective aid is detected upon 
visual examination, 10 additional samples from the same lot must be 
selected at random and examined for the defect.
    (d) If one or more of the 10 samples fails the examination, each 
thermal protective aid in the lot must be examined for the defect for 
which the lot was rejected. Only thermal protective aids that are free 
of defects may be sold as Coast Guard approved.

    (d) Comfort. The lifejacket must not cause significant discomfort to 
the wearer during and after inflation.



Sec.  160.176-13  Approval Tests.

    (a) General. (1) This section contains requirements for approval 
tests and examinations of inflatable lifejackets. Each test or 
examination must be conducted or supervised by an independent 
laboratory. The tests must be done using lifejackets that have been 
constructed in accordance with the plans and specifications in the 
application for approval. Unless otherwise specified, only one 
lifejacket, which may or may not have been subjected to other tests, is 
required to be tested in each test. One or more lifejackets that have 
been tested as prescribed in paragraph (h) of this section must be used 
for the tests prescribed in paragraphs (j), (n), (q), and (r) of this 
section. The tests prescribed in paragraph (y) of this section require 
one or more lifejackets as specified in that paragraph.
    (2) All data relating to buoyancy and pressure must be taken at, or 
corrected to, an atmospheric pressure of 760 mm (29.92 inches) of 
mercury and a temperature of 20 [deg]C (68 [deg]F).
    (3) The tests in this section are not required to be run in the 
order listed, except where a particular order is specified.
    (4) Some tests in this section require a lifejacket to be tested 
while being worn. In each of these tests the test subjects must 
represent a range of small, medium, and large heights and weights. 
Unless otherwise specified, a

[[Page 297]]

minimum of 18 test subjects, including both males and females, must be 
used. The test subjects must not be practiced in the use of the 
lifejacket being tested. However, they must be familiar with the use of 
other Coast Guard approved lifejackets. Unless specified otherwise, test 
subjects must wear only swim suits. Each test subject must be able to 
swim and relax in the water.

    Note: Some tests have inherent hazards for which adequate safeguards 
must be taken to protect personnel and property in conducting the tests.

    (b) Donning. (1) No second stage donning is allowed in the tests in 
this paragraph. Test subjects may read the donning instructions to be 
provided with the device, if any. An uninflated lifejacket with size 
adjustment at its mid-range is given to each test subject with the 
instruction: ``Please don as quickly as possible, adjust to fit snugly, 
and inflate.'' Each subject must, within one minute, don the uninflated 
lifejacket, adjust it to fit snugly, and then activate the manual 
inflation mechanism.

    Note: For this test the manual inflation mechanism may be disabled.

    (2) The average time of all subjects to complete the test in 
paragraph (b)(1) of this section must not exceed 30 seconds. The 
criteria in this paragraph do not apply to the tests in paragraphs 
(b)(3) and (b)(4) of this section.
    (3) The test in paragraph (b)(1) of this section is repeated with 
each subject wearing an insulated, hooded parka and gloves made from 
heavy, cotton-jersey (knit) fabric.
    (4) The test in paragraph (b)(1) of this section is then repeated 
twice more with a fully inflated lifejacket. In the first test the 
subjects must wear swim suits and in the second test, parka and gloves.
    (c) Inflation Testing. No second stage donning is allowed in the 
tests in this paragraph. A lifejacket with each automatic inflation 
mechanism disabled must be used for the tests prescribed in paragraphs 
(c)(1) and (c)(2) of this section. For the tests prescribed in paragraph 
(c)(4) of this section, remove any non-reusable cover or packaging from 
the lifejacket, but do not open any cover or closure which is intended 
to be closed when the lifejacket is worn in the uninflated condition.
    (1) Each test subject dons an uninflated lifejacket and is 
instructed to enter the water and swim for approximately 30 seconds and 
then, on command, inflate the lifejacket using only oral inflation 
mechanisms. Within 30 seconds after the command is given, the lifejacket 
must be sufficiently inflated to float each subject with respiration 
unimpeded.
    (2) Each test subject dons an uninflated lifejacket and is 
instructed to enter the water and swim for approximately 30 seconds, 
bring both hands to the surface, and then, on command, inflate the 
lifejacket using each manual inflation mechanism. Each test subject must 
find and operate all the manual inflation mechanisms within 5 seconds 
after the command is given. The manual inflation mechanisms must inflate 
the lifejacket sufficiently to float the wearers within 5 seconds after 
the mechanisms are operated. Within 20 seconds after activation each 
subject must be floating in the position described in paragraph (d)(3) 
of this section.
    (3) One small and one large test subject don uninflated lifejackets 
and jump feet first from a height of 1 meter into the water. The 
automatic inflation mechanisms must inflate the lifejackets sufficiently 
to float the wearers within 10 seconds after the subjects enter the 
water. Within 20 seconds after entering the water each subject must be 
floating in the position described in paragraph (d)(3) of this section.
    (4) Air at a pressure of 4.2 kPa (0.6 psig) is applied separately to 
each oral inflation mechanism of the lifejacket. In each application the 
chamber must fully inflate within 1 minute.
    (5) Each oral inflation mechanism of an unpacked lifejacket is 
connected to a regulated air source constantly supplying air at a 
pressure of 7 kPa (1 psig). Each mechanism must pass at least 100,000 cc 
of air per minute.
    (d) Flotation stability--(1) Uninflated flotation stability. 
Lifejackets with their automatic inflation mechanisms disabled must be 
used for this test. Each subject dons an uninflated lifejacket,

[[Page 298]]

enters the water, and assumes an upright, slightly back of vertical, 
position. Each subject then relaxes. For each subject that floats, the 
uninflated lifejacket must not tend to turn the wearer face-down when 
the head is allowed to fall back.
    (2) Righting action. (i) Each test subject dons an uninflated 
lifejacket, enters the water, allows the automatic inflation mechanism 
to inflate the lifejacket, and swims for 30 seconds. While swimming, 
freedom of movement and comfort are observed and noted by the person 
conducting the test. Freedom of movement and comfort must comply with 
Sec.  160.176-11(d). Also, each subject must demonstrate that the 
lifejacket can be adjusted while the subject is in the water.
    (ii) Each subject then takes three gentle breast strokes and while 
still face-down in the water, relaxes completely while slowly exhaling 
to FRC. Each subject remains in this limp position long enough to 
determine if the lifejacket will turn the subject from the face-down 
position to a position in which the subject's breathing is not impaired. 
The time from the last breast stroke until breathing is not impaired is 
recorded. Each subject repeats these steps two additional times, and the 
average time for the three righting actions is calculated. This average 
time must not exceed 5 seconds.
    (iii) If the lifejacket does not have automatic inflation mechanisms 
for all chambers, the tests in paragraphs (d)(2)(i) and (d)(2)(ii) of 
this section are repeated with each lifejacket fully inflated.
    (iv) Each subject then performs the test in paragraph (d)(2)(ii) of 
this section with one chamber of the lifejacket deflated. This test is 
then repeated as many times as necessary to test the lifejacket with a 
different chamber deflated until each chamber has been tested in this 
manner.
    (v) Each subject then performs the test in paragraph (d)(2)(ii) of 
this section but exhales to FRC at the end of the third breast stroke 
and holds the breath prior to relaxing.
    (3) Static measurements. At the end of each test with each subject 
in Sec.  160.176-13(d)(2)(ii), through Sec.  160.176-13(d)(2)(v)--
    (i) The freeboard (the distance from the water surface to the bottom 
of the mouth) must be at least 100 mm (4.0 in.) without repositioning of 
any part of the body and at least 120 mm (4.75 in.) after the head is 
positioned on the lifejacket for maximum freeboard and then relaxed;
    (ii) The distance from water surface to the lower portion of the ear 
canal must be at least 50 mm (2 in.);
    (iii) The torso angle (the angle between a vertical line and a line 
passing through the shoulder and hip) must be between 20[deg] and 
65[deg] (back of vertical);
    (iv) The face-plane angle (the angle between a vertical line and a 
line passing through the most forward part of the forehead and chin) 
must be between 15[deg] and 60[deg] (back of vertical);
    (v) The lowest mark on a vertical scale 6 m (20 ft.) from and in 
front of the subject which the subject can see without moving the head 
must be no higher than 0.3 m (12 in.) from the water level.
    (vi) The subject when looking to the side, must be able to see the 
water within 3 m (10 ft.) away; and
    (vii) At least 75% of the retroreflective material on the outside of 
the lifejacket, and the PFD light, must be above the water.
    (4) Average requirements. The test results for all subjects must be 
averaged for the following static measurements and must comply with the 
following:
    (i) The average freeboard prior to positioning the head for maximum 
freeboard must be at least 120 mm (4.75 in.);
    (ii) The average torso angle must be between 30[deg] and 50[deg] 
(back of vertical); and
    (iii) The average face-plane angle must be between 20[deg] and 
50[deg] (back of vertical).
    (5) ``HELP'' Position. Starting in a relaxed, face-up position of 
static balance, each subject brings the legs and arms in towards the 
body so as to attain the ``HELP'' position (a fetal position, but 
holding the head back). The lifejacket must not turn the subject face 
down in the water.
    (e) Jump test. (1) Each test subject dons an uninflated lifejacket 
and with hands above head, jumps feet first, into the water from a 
height of 4.5 m (15 ft.).

[[Page 299]]

No second stage donning is allowed during this test and the lifejacket 
must--
    (i) Inflate automatically, float the subject to the surface, and 
stabilize the body with the mouth out of the water;
    (ii) Maintain its intended position on the wearer;
    (iii) Not be damaged; and
    (iv) Not cause injury to the wearer.
    (2) The jump test in paragraph (e)(1) of this section is repeated 
using a lifejacket which has been fully inflated manually.
    (3) The jump test in paragraph (e)(2) of this section is then 
conducted with one chamber deflated. This test is then repeated as many 
times as necessary to test the lifejacket with a different chamber 
deflated until each chamber has been tested in this manner.

    Note: Before conducting these tests at the 4.5 m height, subjects 
should first do the test from heights of 1 m and 3 m to lessen the 
possibility of injury. It is suggested that subjects wear a long-sleeve 
cotton shirt to prevent abrasions when testing the device in the 
inflated condition and that the teeth should be tightly clenched 
together when jumping.

    (f) Water emergence--(1) Equipment. A pool with a wooden platform at 
one side must be used for this test. The platform must be 300 mm (12 
in.) above the water surface and must not float on the water. The 
platform must have a smooth painted surface. Alternatively, a Coast 
Guard approved inflatable liferaft may be used in lieu of a platform.
    (2) Qualifying. Each test subject enters the water wearing only a 
bathing suit and swims 25 m. The subject must then be able to emerge 
from the pool onto the platform using only his or her hands on the top 
of the platform as an aid and without pushing off of the bottom of the 
pool. Any subject unable to emerge onto the platform within 30 seconds 
is disqualified for this test. If less than \2/3\ of the test subjects 
qualify, substitute subjects must be used.
    (3) Test. Each qualified subject dons an inflated lifejacket, enters 
the water and swims 25 m. Afterward, at least \2/3\ of the qualified 
subjects must then be able to climb out of the pool in the manner 
prescribed in paragraph (f)(2) of this section within 45 seconds while 
wearing the lifejacket. If marking on the lifejacket so indicates, and 
if the wearer can read the marking while the lifejacket is being worn, 
the subjects may deflate the device during the 45 second attempt.
    (g) Lanyard pull test and strength. (1) An uninflated lifejacket is 
placed on a rigid metal test form built according to Figure 160.176-
13(n)(2) and suspended vertically.
    (2) The inflation handle of each manual inflation mechanism is 
attached to a force indicator. The force indicator is then used to 
activate each manual inflation mechanism separately. The force required 
to activate each mechanism is recorded. In each test the force must be 
between 25 and 70 N (5 and 15 lb.).
    (3) A weight of 225 N (50 lb.) is in turn attached to the inflation 
handle of each manual inflation mechanism. The weight is then allowed to 
hang freely for 5 minutes from each manual inflation mechanism. The 
handle must not separate from the mechanism.
    (h) Temperature cycling tests. (1) Three uninflated lifejackets, 2 
packed and 1 unpacked, are maintained at room temperature (20 3 [deg]C (68 + 6 [deg]F)) for 4 hours and then at a 
temperature of 65 2 [deg]C (150 5 [deg]F) for 20 hours. The lifejackets are then 
maintained at room temperature for at least 4 hours, after which they 
are maintained at a temperature of minus 30 2 
[deg]C (-22 5 [deg]F) for 20 hours. This cycle is 
then repeated once.
    (2) Upon the completion of the conditioning in paragraph (h)(1) of 
this section all sealed or non-reusable packaging is removed from the 
two packed units. The lifejackets must show no functional deterioration 
after being inflated immediately after removal from the conditioning. 
The lifejackets must be inflated as follows:
    (i) One unit which was packed during conditioning must fully inflate 
within 2 minutes using only oral inflation.
    (ii) The other unit which was packed during conditioning must fully 
inflate within 45 seconds of submersion in water at 2 2 [deg]C (37 5 [deg]F) as a result 
of automatic inflation.
    (iii) The unit which was unpacked during conditioning must fully 
inflate within 30 seconds of activation of the manual inflation 
mechanisms.

[[Page 300]]

    (3) The same 3 lifejackets used for the test in paragraph (h)(1) of 
this section are deflated and, with 2 repacked and 1 unpacked, are 
maintained at room temperature for 4 hours and then at a temperature of 
minus 30 2 [deg]C (-22 5 
[deg]F) for 20 hours. The lifejackets are then stored at room 
temperature for at least 4 hours, after which they are maintained at a 
temperature of 65 2 [deg]C (150 5 [deg]F) for 20 hours. This cycle is then repeated 
once. The steps in paragraph (h)(2) of this section are then repeated, 
and the lifejackets must meet the criteria in that paragraph.
    (i) [Reserved]
    (j) Buoyancy and inflation medium retention test. A lifejacket which 
has been used in the tests in paragraph (h) of this section must be used 
for this test.
    (1) Equipment. The following equipment is required for this test:
    (i) A wire mesh basket that is large enough to hold the inflated 
lifejacket without compressing it, is designed not to allow the 
lifejacket to float free, and is heavy enough to overcome the buoyancy 
of the lifejacket.
    (ii) A scale that is sensitive to 14 g (0.5 oz.) and that has an 
error of less than 14 g (0.5 oz.).
    (iii) A test tank, filled with fresh water, that is large enough to 
hold the basket with its top 50 mm (2 in.) below the surface without the 
basket touching the tank.
    (2) Method. One inflation chamber is inflated using its automatic 
inflation mechanism. The lifejacket is placed in the basket. The basket 
is then suspended from the scale and submerged in the test tank with the 
lifejacket and basket completely below the water surface. An initial 
reading of the scale is taken after 30 minutes and again after 24 hours. 
The buoyancy of the lifejacket is the submerged weight of the basket 
minus the submerged weight of the basket with the lifejacket inside. 
This test is repeated as many times as necessary until each chamber has 
been tested. On each chamber that does not have an automatic inflation 
mechanism the manual or oral inflation mechanism may be used.
    (3) Requirement. The buoyancy of each inflation chamber must be 
within the tolerances specified in the plans and specifications for the 
lifejacket required by Sec.  160.176-5(a)(2) of this part. Each 
inflation chamber must retain at least 95% of its initial buoyancy after 
being submerged for 24 hours.
    (k) Uninflated floatation test. A packed lifejacket, with all 
automatic inflation mechanisms disabled, is dropped from a height of 1 m 
(3 ft.) into fresh water. The lifejacket must remain floating on the 
surface of the water for at least 30 minutes. This test is repeated with 
an unpacked, uninflated lifejacket, with all automatic inflation 
mechanisms disabled.
    (l) [Reserved]
    (m) Environmental tests--(1) Salt spray exposure. An uninflated 
lifejacket is subjected to 720 hours of salt spray as specified by ASTM 
B 117 (incorporated by reference, see Sec.  160.176-4). The automatic 
inflation mechanism(s) must not be activated by the salt spray. The 
lifejacket is then inflated first using the automatic inflation 
mechanism(s) and then twice more using first the manual mechanisms and 
then the oral mechanisms. The lifejacket must show no functional 
deterioration.
    (2) Rain exposure. An uninflated lifejacket is mounted on a rigid 
metal test form built according to Figure 160.176-13(n)(2). The test 
form must be vertical. Spray nozzles that deliver 0.05 mm of water per 
second (0.7 inch/hour) over the area of the lifejacket at a temperature 
between 2 and 16 [deg]C (35 and 60 [deg]F) and at a 45[deg] angle below 
horizontal toward the lifejacket are mounted 1.5 m (4.5 ft.) above the 
base of the test form. There must be at least 4 nozzles evenly spaced 
around the lifejacket at a horizontal distance of 1 m from the center of 
the lifejacket and each nozzle must deliver water at the same rate. 
Water is then sprayed on the lifejacket for 1 hour. The lifejacket must 
not inflate during the test.
    (n) Tensile tests. Two lifejackets that have been subjected to the 
tests in paragraph (h) of this section must be used for these tests.
    (1) Body tensile test. (i) In this test one lifejacket must be fully 
inflated and the other deflated.
    (ii) Two unconnected rigid cylinders are passed through the body 
portion of each lifejacket, or through the encircling body strap for

to its mid range, as shown in Figure 160.176-13(n)(1). Each cylinder 
must be 125 mm (5 inches) in diameter. The top cylinder is connected to 
a winch or pulley system. The bottom cylinder is connected to a test 
load which when combined with the weight of the lower cylinder and the 
linkage equals 325 kg (720 lb.). The winch or pulley system lifts the 
top cylinder so the test load is raised off of its support. The test 
load is left suspended for 30 minutes.
    (iii) There must be no functional deterioration of any component of 
either lifejacket during the test. Each friction type closure must not 
permit slippage of more than 25 mm (1 in.).
    (iv) If a lifejacket has friction type closures, the test must be 
repeated immediately after the lifejacket has been immersed in water for 
a least 2 minutes.
    (v) The test is repeated until each different type of closure is 
tested separately.

    (2) Shoulder tensile test. Each shoulder section of a lifejacket is 
subjected to this test separately. A fully inflated lifejacket, with all 
closures fastened, must be secured to a rigid metal test form built 
according to Figure 160.176-13(n)(2). A 2 \1/4\ 
in. wide web is passed through the shoulder section of the lifejacket 
and is connected to a winch or pulley system. The bottom portion of the 
form is connected to a dead weight load which when combined with the 
weight of the form and the linkage equals 90 kg. (200 lb.). The winch or 
pulley system is operated to raise the weight off of its support. The 
weight is left suspended for 30 minutes. There must be no functional 
deterioration of any component of the lifejacket during the test.

    (3) Strength of attachment of inflation mechanism. (i) A fully 
inflated lifejacket is secured to a rigid metal test form as in Figure 
160.176-13(n)(2), and the pressure of each inflated chamber is measured. 
The top portion of the form is then connected to a winch or pulley 
system. A 35 kg (75 lb.) weight is attached by a line to one of the 
inflation mechanisms as close as possible to the point of attachment on 
the lifejacket. The winch or pulley system is operated to raise the 
weight off of its support. The weight is left suspended for 5 minutes 
and then released. The inflation chamber to which the inflation 
mechanism is attached must not lose more than 3 kPa (0.4 psig) or 20% of 
its original pressure.
    (ii) The test is paragraph (n)(3)(i) of this section is repeated 
until each type of inflation mechanism has been tested separately.
    (iii) The test is then repeated as many additional times as 
necessary to test each joint in each type of inflation mechanism beyond 
its point of attachment to an inflation chamber. In each test the point 
of attachment must be as close as possible to the joint being tested.
    (o) [Reserved]
    (p) Impact test. (1) an uninflated lifejacket is secured to the test 
form shown in Figure 160.176-13(n)(2). The lifejacket, with the 
automatic inflation mechanism disabled, is secured to the form as it is 
intended to be worn. The lifejacket is accelerated to 25 m/s (50 mph) 
horizontally and is then dropped from a height of not more than 0.5 m 
(1.5 ft.) into the water in the following positions:
    (i) Face down, shoulder forward.
    (ii) Face down, shoulder back.
    (iii) Back down, shoulder forward.
    (iv) Back down, shoulder back.
    (v) Left side down, shoulder forward.
    (vi) Right side down, shoulder back.
    (2) Following each impact, there must be no sign of functional 
deterioration, and the lifejacket must not come off of the test form. 
After each

[[Page 304]]

impact the closures may be readjusted as necessary.
    (3) Following the six impacts, the lifejacket must fully inflate 
using only its oral inflation mechanisms.
    (4) The test in this paragraph is repeated on the same lifejacket 
after inflating, with manual inflation mechanisms, all chambers that 
have those mechanism.
    (q) Flame exposure test. A lifejacket that has been subjected to the 
tests in paragraph (h) of this section must be used for this test.
    (1) Equipment. The following equipment is required for this test:
    (i) A test pan 300 mm by 450 mm by 60 mm (12 in. by 18 in. by 2\1/2\ 
in.) containing 12 mm (\1/2\ in.) of water under 25 mm (1 in.) of N-
heptane.
    (ii) an arrangement to hold the lifejacket over the N-heptane.
    (2) Method. The test is only conducted when there is no significant 
air movement other than that caused by the fire. The N-heptane is 
ignited and allowed to burn for 30 seconds. A lifejacket which has been 
fully inflated with air is then passed through the flames in an upright, 
forward, vertical, free-hanging position with the bottom of the 
lifejacket 240 mm C 9\1/2\ in.) above the top edge of the test pan. The 
lifejacket is exposed to the flames for 2 seconds.
    (3) Requirement. The lifejacket must not burn or melt for more than 
6 seconds after being removed from the flames. The lifejacket must 
remain inflated throughout the test. If the lifejacket sustains any 
visible damage other than discoloration after being exposed to the 
flames, the lifejacket must--
    (i) pass the test in paragraph (e)(2) of this section, except that 
only one subject is used and the test is done six times; and
    (ii) pass the tensile test in paragraph (n)(1) of this section, 
except that a weight of 245 kg (540 lb.) is used in lieu of the 325 kg 
(720 lb.) weight.
    (r) Solvent exposure test. Lifejackets with their automatic 
inflation mechanisms disabled must be used for this test. Two uninflated 
lifejackets that have been subjected to the tests in paragraph (h) of 
this section are totally submerged in diesel fuel, grade No. 2-D as 
defined in ASTM D 975 (incorporated by reference, see Sec.  160.176-4), 
for 24 hours. The lifejackets are then removed and the excess fuel 
removed. One lifejacket must fully inflate using only its manual 
inflation mechanisms and the other using only its oral inflation 
mechanisms. The lifejackets must show no functional deterioration as a 
result of the test.
    (s) Puncture test. A fully inflated lifejacket is placed on a flat, 
level surface. A test point 4 mm (\5/32\ in.) in diameter tapering to a 
rounded point, 1 mm (\3/64\ in.) in diameter, is pressed against an 
inflation chamber of the lifejacket perpendicular to the surface of the 
chamber at a rate of 300 mm/minute (12 in./minute). The test point is 
applied until the inflation chamber is punctured or the chamber walls 
are touching each other. The force required to puncture the inflation 
chamber or make the chamber walls touch each other is recorded. The 
force required must exceed 30 N (7 lb.).
    (t) Inflation chamber tests--(1) Over-pressure test. One lifejacket 
is used in this test. Before pressurizing the lifejacket, each over-
pressure valve, if any, must be blocked. One inflation chamber is then 
pressurized with air to 70 kPa (10 psig) and held for 5 minutes. After 
the 5 minute period, there must be no sign of permanent deformation, 
damage, or pressure loss of more than 3.5 kPa (0.5 psig). This test is 
then repeated as many times as necessary to test a different chamber 
until each chamber has been tested in this manner.
    (2) Air retention test. One inflation chamber of a lifejacket is 
filled with air until air escapes from the over-pressure valve or, if 
the lifejacket does not have an over-pressure valve, until its design 
pressure, as stated in the plans and specifications, is reached. After 
12 hours the lifejacket must still be firm with an internal pressure of 
at least 14 kPa (2.0 psig). This test is then repeated as many times as 
necessary to test a different chamber until each chamber has been tested 
in this manner.
    (u) Seam strength test. Samples of each type of structural sewn seam 
must be subjected to and pass the ``Seam Strength (Sewability) Test''

[[Page 305]]

specified in Underwriters Laboratories Standard UL 1191 except that the 
breaking strength of each seam in the directions of both greater and 
lesser thread count must be at least 400 N (90 lb.).
    (v) [Reserved]
    (w) Visual examination. One complete lifejacket must be visually 
examined for compliance with the requirements of Sec. Sec.  160.176-9 
and 160.176-11 of this part
    (x) [Reserved]
    (y) Inflation chamber properties. The tests in this paragraph must 
be run after successful completion of all other approval tests. The 
results of these tests will be used to check the quality of incoming 
lifejacket components and the production process. Test samples must come 
from one or more lifejackets that were each used in all of the tests in 
paragraphs (e), (j), (p), (s), and (t) of this section.
    (1) Grab breaking strength. The grab breaking strength of chamber 
materials must be determined according to Method No. 5100 of Federal 
Test Method Standard 191A or ASTM D 751 (incorporated by reference, see 
Sec.  160.176-4).
    (2) Tear strength. The tear strength of chamber materials must be 
determined according to Method No. 5132 or 5134 of Federal Test Method 
Standard 191A or ASTM D 751 (incorporated by reference, see Sec.  
160.176-4).
    (3) Permeability. The permeability of chamber materials must be 
determined according to ASTM D 1434 (incorporated by reference, see 
Sec.  160.176-4) using CO2 as the test gas.
    (4) Seam strength. The seam strength of the seams in each inflation 
chamber of at least one lifejacket must be determined according to ASTM 
D 751 (incorporated by reference, see Sec.  160.176-4) except that 25 by 
200 mm (1 by 8 in.) samples may be used where insufficient length of 
straight seam is available.
    (z) Additional tests. The Commandant may prescribe additional tests, 
if necessary, to approve novel or unique designs.

Sec.  160.176-15  Production tests and inspections.

    (a) General. (1) Production tests and inspections must be conducted 
in accordance with this section and subpart 159.007 of this chapter.
    (2) The Commandant may prescribe additional production tests and 
inspections if needed to maintain quality control and check for 
compliance with the requirements in this subpart.
    (b) Test and inspection responsibilities. In addition to 
responsibilities set out in part 159 of this chapter, each manufacturer 
of an inflatable lifejacket and each independent laboratory inspector 
must comply with the following, as applicable:
    (1) Manufacturer. Each manufacturer must--
    (i) Perform all required tests and examinations on each lifejacket 
lot before the independent laboratory inspector tests and inspects the 
lot;
    (ii) Perform required testing of each incoming lot of inflation 
chamber material before using that lot in production;
    (iii) Have procedures for maintaining quality control of the 
materials used, manufacturing operations, and the finished product;
    (iv) Have a continuing program of employee training and a program 
for maintaining production and test equipment;
    (v) Have an inspector from the independent laboratory observe the 
production methods used in producing the first lifejacket lot produced 
and observe any revisions made thereafter in production methods;
    (vi) Admit the inspector and any Coast Guard representative to any 
place in the factory where work is done on lifejackets or component 
materials, and where completed lifejackets are stored; and
    (vii) Allow the inspector and any Coast Guard representative to take 
samples of completed lifejackets or of components materials for tests 
prescribed in this subpart.
    (2) Independent laboratory. (i) An inspector may not perform or 
supervise any production test or inspection unless--
    (A) The manufacturer has a current approval certificate; and

[[Page 306]]

    (B) The inspector has first observed the manufacturer's production 
methods and any revisions to those methods.
    (ii) An inspector must perform or supervise all required tests and 
inspections of each lifejacket lot produced.
    (iii) During each inspection, the inspector must check for 
noncompliance with the manufacturer's quality control procedures.
    (iv) At least once each calendar quarter, the inspector must, as a 
check on manufacturer compliance with this section, examine the 
manufacturer's records required by Sec.  160.176-17 of this part and 
observe the manufacturer in performing each of the tests required by 
paragraph (h) of this section.
    (c) Lifejacket lots. A lot number must be assigned to each group of 
lifejackets produced. No lot may exceed 1000 lifejackets. A new lot must 
be started whenever any change in materials or a revision to a 
production method is made, and whenever any substantial discontinuity in 
the production process occurs. Changes in lots of component materials 
must be treated as changes in materials. Lots must be numbered serially. 
The lot number assigned, along with the approval number, must enable the 
lifejacket manufacturer, by referring to the records required by this 
subpart, to determine who produced the components used in the 
lifejacket.
    (d) Samples. (1) Samples used in testing and inspections must be 
selected at random. Sampling must be done only when all lifejackets or 
materials in the lot are available for selection.
    (2) Each sample lifejacket selected must be complete, unless 
otherwise specified in paragraph (h) of this section.
    (3) The inspector may not select the same samples tested by the 
manufacturer.

\1\ Samples selected for this test may not be the same lifejackets selected for other tests.
\2\ This test may be omitted if the manufacturer has previously conducted it on the lot and the inspector has
  conducted the test on a previous lot during the same calendar quarter.
\3\ One sample of each means of marking on each type of fabric or finish used in lifejacket construction must be
  tested. This test is only required when a new lot of materials is used. However, the test must be run at least
  once every calendar quarter regardless of whether a new lot of materials is started in that quarter.

    (e) Accept/reject criteria: manufacturer testing. (1) A lifejacket 
lot passes production testing if each sample passes each test.
    (2) In lots of 200 or fewer lifejackets, the lot must be rejected if 
any sample fails one or more tests.
    (3) In lots of more than 200 lifejackets, the lot must be rejected 
if--

an organization that is an accepted independent laboratory, as defined 
in 46 CFR 159.010, or a nationally recognized testing laboratory, as set 
forth in 29 CFR 1910.7, whose listing states that either the equipment 
or material meets appropriate designated standards.
    Nationally recognized testing laboratory (NRTL) means an 
organization that the Occupational Safety and Health Administration 
(OSHA) has recognized as meeting the requirements in 29 CFR 1910.7. 
These requirements are for the capability, control programs, complete 
independence, and reporting and complaint-handling procedures to test 
and certify specific types of products for workplace safety. This means, 
in part, that an organization must have the necessary capability both as 
a product safety testing laboratory and as a product certification body 
to receive OSHA recognition as an NRTL.
    Sample extraction smoke detection systems means systems that collect 
and analyze air samples from protected spaces in order to detect 
products of combustion. A complete system includes a control unit, a 
blower box, accumulators, and a piping system with associated fittings.

Sec.  162.017-2  Type.

    This specification covers the design and construction of pressure-
vacuum relief valves intended for use in venting systems on all tank 
vessels transporting inflammable or combustible liquids.

[56 FR 35827, July 29, 1991]



Sec.  162.017-3  Materials, construction, and workmanship.

    (a) The valves shall be of substantial construction and first class 
workmanship and shall be free from imperfections which may affect its 
serviceability.
    (b) Bodies of pressure-vacuum relief valves must be made of bronze 
or such corrosion-resistant material as may be approved by the 
Commanding Officer, USCG Marine Safety Center.
    (c) Valve discs, spindles, and seats shall be made of bronze or such 
corrosion-resistant material as may be approved by the Commanding 
Officer, USCG Marine Safety Center.
    (d) Where springs are employed to actuate the valve discs, the 
springs shall be made of corrosion-resistant material. Springs plated 
with corrosion-resistant material are not acceptable.
    (e) Flame screens shall be made of corrosion-resistant wire.
    (f) Nonmetallic materials will not be permitted in the construction 
of the valves, except bushings used in way of

[[Page 328]]

moving parts and gaskets may be made of nonmetallic material resistant 
to attack by the product carried. Nonmetallic diaphragms will be allowed 
where diaphragm failure will not result in unrestricted flow of cargo 
vapors to the atmosphere nor in an increase in the pressure or vacuum at 
which the valve normally releases.
    (g) The design and construction of the valves shall permit 
overhauling and repairs without removal from the line.
    (h) Valve discs shall be guided by a ribbed cage or other suitable 
means to prevent binding, and to insure proper seating. Where valve 
stems are guided by bushings suitably designed to prevent binding and to 
insure proper seating, the valves need not be fitted with ribbed cages.
    (i) The disc shall close tight against the valve seat by metal to 
metal contact, however, resilient seating seals may be provided if the 
design is such that the disc closes tight against the seat in case the 
seals are destroyed or in case they carry away.
    (j) Pressure-vacuum relief valves for venting cargo tanks shall be 
of not less than 2\1/2\ inches nominal pipe size.
    (k) Bodies of valves shall be designed to withstand a hydrostatic 
pressure of at least 125 pounds per square inch without rupturing or 
showing permanent distortion.
    (l) The valve discs may be solid or made hollow so that weight 
material may be added to vary the lifting pressure. If hollow discs are 
employed, a watertight bolted cover shall be fitted to encase the weight 
material. The pressure at which the discs open shall not exceed 120 
percent of the set pressure.
    (m) The free area through the valve seats at maximum lift shall not 
be less than the cross-sectional area of the valve inlet connection.
    (n) Double flame screens of 20 x 20 corrosion-resistant wire mesh 
with a \1/2\-inch corrosion-resistant separator on a single screen of 30 
x 30 corrosion-resistant wire mesh shall be fitted on all openings to 
atmosphere. The net free area through the flame screens shall not be 
less than 1\1/2\ times the cross-sectional area of the vent inlet from 
the cargo tanks.
    (o) Valve bodies may have screwed or flanged pipe connections, or 
such types of connections as may be approved by the Commanding Officer, 
USCG Marine Safety Center. If flanged, the thickness and drilling shall 
comply with USA standards for 150-pound bronze flanged fittings.
    (p) Where design of valve does not permit complete drainage of 
condensate to attached cargo tank or vent line, the valve body shall be 
fitted with a plugged drain opening on the side of the atmospheric 
outlet of not less than \1/2\ inch pipe size.
    (q) Relief pressure adjusting mechanisms shall be permanently 
secured by means of lockwires, locknuts, or other acceptable means.
    (r) Pressure-vacuum relief valves constructed in accordance with ISO 
15364 (incorporated by reference; see 46 CFR 162.017-1) meet the 
requirements of this subpart.

Sec.  162.050-23  Separator: Approval tests.

    (a) Test Conditions. (1) Each test described in this section must be 
performed at a throughput and influent pressure equal to the maximum 
throughput and pressure at which the separator being tested is designed 
to operate. The tests and each of the steps in the tests must be carried 
out in the order described in this section. Each test must be performed 
without time delay between steps in the test.
    (2) A test rig of the type described in Sec.  162.050-17 must be 
used in performing each test.
    (3) If a separator has a supply pump, it must be tested using that 
pump. If a separator does not have a supply pump, it must be tested 
using the mixture pump on the test rig.
    (4) The influent water used in each test must be clean fresh water 
or clean fresh water in solution with sodium chloride. In either case, 
the relative density of the water must be no greater than 1.015 at 20 
[deg]C.
    (5) Each test must be conducted at an ambient temperature of between 
10 [deg]C and 30 [deg]C.
    (6) The oil content of each sample must be measured using the method 
described in Sec.  162.050-39.
    (7) Influent oil content must be determined during testing by 
measuring the flow rates of the oil and water that are mixed to form the 
influent or by use of an oil content meter on the inlet piping of the 
test rig. If an oil content meter is used, a sample of influent and a 
meter reading must be taken at the beginning of each test. If the meter 
reading is not within 10 percent of the oil 
content of the sample, the meter readings subsequently taken during the 
test are unacceptable test results.
    (8) When collecting a sample at a sample point that has a stop cock, 
the first minute of fluid flow through the stop cock must not be 
included in the sample collected.
    (9) In each test, the separator must be operated in accordance with 
the procedures described in its instruction manual.
    (10) No maintenance, including replacement of parts, may be 
performed on a separator during or between the tests described in this 
section.
    (11) A 1 liter sample of each oil to be used in testing must be 
taken and provided for use in the sample analysis required by Sec.  
162.050-39 .
    (12) The separator may not be operated manually in Test No. 5A.
    (13) If a separator has an integral bilge alarm, the separator must 
be tested with the bilge alarm installed.
    (b) The following tests must be conducted using Test Fluid A:
    (1) Test No. 1A. The separator is filled with water and started. 
Next, the separator is fed with pure Test Fluid A for at least 5 minutes 
and then with a mixture of Test Fluid A and water influent containing 
Test Fluid A content of between 5,000 and 10,000 ppm until a steady flow 
rate at a steady, constant ppm occurs. After the flow rate is steady, 
the influent is fed to the separator for 30 minutes. Samples of 
separated water effluent are taken after the first 10 and 20 minutes. At 
the end of the 30-minute period, the air cock on the test rig is opened 
and, if necessary, the oil and water supply valves are closed to stop 
the flow of influent. A sample is then taken of the separated water 
effluent as the effluent flow ceases.
    (2) Test No. 2A. Repeat Test No. 1A in paragraph (b)(1) of this 
section using an influent containing approximately 25 percent oil and 75 
percent water. Percentage is on a by volume basis.
    (3) Test No. 3A. The separator is fed with 100 percent Test Fluid A 
until Fluid A is discharged at the oil discharge outlet of the separator 
at essentially the same rate that oil is being fed to the separator. The 
separator is then fed with 100 percent Test Fluid A for 5 additional 
minutes. If any oily

[[Page 350]]

mixture is discharged from the separated water outlet on the separator 
during the test, that observation is recorded.
    (4) Test No. 4A. The separator is fed with water for 15 minutes. 
Samples of the separated water effluent are taken at the beginning of 
the test and after the first 10 minutes.
    (5) Test No. 5A. The separator is operated automatically for 3 
hours. During the test, the separator is continuously fed with an 
influent varying from water to a mixture of 25 percent Test Fluid A in 
water and back to water every 15 minutes. The Test Fluid A concentration 
in the influent is varied in at least five equal increments during each 
15-minute period and the time intervals between the incremental changes 
are equal. During the last hour, the separator must be inclined at an 
angle of 22.5[deg] with the plane of its normal operating position. 
During the last time increment in which the unit is fed a 25 percent 
Fluid A mixture, a sample of the separated water effluent is taken. If 
the separator stops at any time during this test, that observation is 
recorded.
    (c) The following tests must be conducted using Test Fluid B:
    (1) Test No. 1B. Repeat Test No. 1A in paragraph (b)(1) of this 
section using Test Fluid B; and
    (2) Test No. 2B. Repeat Test No. 2A in paragraph (b)(2) of this 
section using Test Fluid B.
    (d) The following tests must be conducted using Test Fluid C: Test 
No. 1C. The separator is fed with a mixture composed of 6 percent Test 
Fluid C and 94 percent water by volume such that the emulsified Test 
Fluid C content is approximately 3,000 ppm in the test water until a 
steady flow rate occurs. After the flow rate is steady, the influent 
containing the 6 percent Test Fluid C solution is fed to the separator 
operating automatically for 3 hours. Samples of separated water effluent 
are taken at 50 minutes and 100 minutes. At the end of the 3-hour 
period, the air cock on the test rig is opened and, if necessary, the 
oil and water supply valves are closed to stop the flow of influent. A 
sample is then taken of the separated water effluent as the effluent 
flow ceases.

means that does not involve manually mixing a known quantity of oil and 
a known quantity of water to form a mixture and manually feeding the 
mixture into the monitor.
    (c) The electrical components of a monitor that are to be installed 
in an explosive atmosphere must be approved by an independent laboratory 
as components that Underwriters Laboratories Standard 913 (dated April 
8, 1976) (incorporated by reference, see Sec.  162.050-4) defines as 
intrinsically safe for use in a Class I, Group D hazardous location.
    (d) Each monitor component that is a moving part must be designed so 
that its movement during operation of the monitor does not cause 
formation of static electricity.
    (e) A monitor must be designed to operate in each plane that forms 
an angle of 22.5[deg] with the plane of its normal operating position.
    (f) Each monitor must be designed in accordance with the applicable 
requirements contained in subchapters F and J of this chapter.
    (g) Each monitor must be designed so that it records each change in 
oil content of the mixture it is measuring within 20 seconds after the 
change occurs.
    (h) Each monitor must have a device that produces a warning signal 
and a signal that can be used to actuate valves in a vessel's fixed 
piping system, when--
    (1) The oil content of the mixture being measured exceeds the 
concentration limit set by the operator of the monitor; and
    (2) Malfunction, breakdown, or other failure of the monitor occurs.

[[Page 351]]

    (i) Each monitor must have a means to determine whether it is 
accurately calibrated.

Sec.  162.050-27  Oil content meter: Approval tests.

    This section contains requirements that apply to performing each 
test.
    (a) Test conditions. (1) The tests and each step in the tests must 
be carried out in the order described in this section. Each test must be 
performed without time delay between steps in the test. No maintenance, 
including replacement of parts, may be performed on the meter during or 
between the tests described in this section.
    (2) A test rig of the type described in Sec.  162.050-19 must be 
used when performing each test.
    (3) Each mixture used during the tests must be prepared by combining 
oil supplied from the oil injection pipe of the test rig and water 
supplied from the mixture tank of the test rig. However, if the flow of 
oil through the oil injection pipe becomes intermittent, oil and water 
may be combined in the mixture tank to form the mixture.
    (4) A mixture may be circulated through a meter only once during 
testing.
    (5) Unless otherwise provided in a specific test, the water used in 
each test must be clean, fresh water.
    (6) The oil used in each test, except Test No. 2 in paragraph (c) of 
this section, must be Arabian light crude oil.
    (7) Each test must be performed at an ambient temperature of between 
10 [deg]C and 30 [deg]C.
    (8) Unless otherwise provided in a specific test, each test must be 
performed at the maximum mixture pressure, the maximum flow rate, and 
the power supply ratings at which the meter is designed to operate.
    (9) The particulate contaminant described in Test No. 5 in paragraph 
(f) of this section, if not attapulgite, must be of a type that does not 
lose more than 3 percent of its weight after ignition and must be 
insoluble in a 500 ppm mixture.
    (10) In each test the meter must be operated in accordance with the 
procedures described in its instructions manual.
    (11) Unless otherwise provided in a specific test, the centrifugal 
pump shown in Figure 162.050-19 in Sec.  162.050-19 must be operated at 
1,000 revolutions per minute or more in each test.
    (12) Whenever the oil content of a mixture is recorded, a sample of 
the mixture must also be taken. The oil content of the sample must be 
measured using the method described in Sec.  162.050-39.
    (13) A one-liter sample of each oil to be used in testing must be 
taken and provided for use in the sample analysis required by Sec.  
162.050-39.
    (b) Test No. 1 Calibration and Zero Test. The meter is calibrated 
and zeroed to manufacturer's instructions. It is then fed with water for 
15 minutes and then with mixtures in the following concentrations: 15 
ppm, 50 ppm, 100 ppm, and each additional concentration, in increments 
of 50 ppm up to the highest oil concentration that can be read on the 
meter. Each mixture is fed to the meter in the order listed in Table 
162.050-27(c) for 15 minutes. Water is fed to the meter for a 15-minute 
period between each mixture. At the end of each 15-minute period, an oil 
content reading is obtained and recorded, and a calibration curve must 
be created.
    (c) Test No. 2 Response to Different Oil Types Test. (1) If the 
meter is designed for use with crude oils, it is fed with a mixture of 
water and the first oil listed in Table 162.050-27(c) at the following 
concentrations: 15 ppm, 100 ppm, and a concentration that is 90 percent 
of the highest oil concentration in water that can be read on the meter. 
Each concentration is fed to the meter in the order listed until a 
steady reading occurs and is recorded. After each steady reading is 
recorded, the meter is fed with water for 15 minutes. At the end of each 
15-minute period of feeding the meter with water, an oil content reading 
is again obtained and recorded, and a calibration curve must be created.
    (2) The steps described in paragraph (c)(1) of this section are 
repeated using each of the other oils listed in Table 162.050-27(c). A 
calibration curve must be created for each oil tested.

reduced to one-half of the meter's design flow rate. The reduced flow 
rate or mixture pressure is maintained until a steady oil content 
reading is obtained and recorded.
    (3) If the meter has a positive displacement mixture pump, the 
mixture pressure is increased to twice the meter's design pressure. If 
the meter has a centrifugal mixture pump or does not have a mixture

based tests and evaluations that meet the requirements of the ETV 
Protocol (incorporated by reference, see Sec.  162.060-5). The land-
based testing will determine if the biological efficacy of the BWMS 
under consideration for approval is sufficient to meet the applicable 
ballast water discharge standard (BWDS) and validate those aspects of 
the operating and maintenance parameters presented by the manufacturer 
that are appropriate for assessment under the relatively short-term, but 
well-controlled, circumstances of a land-based test.
    (b) The test set up must operate as described in the ETV Protocol 
Test Plan requirements during at least five consecutive, valid, and 
successful replicate test cycles. No adjustments to the BWMS are 
permitted unless specifically detailed in the Operation, Maintenance and 
Safety Manual. The BWMS must be operated by independent laboratory or 
independent laboratory subcontractor personnel.
    (c) Each valid test cycle must include--
    (1) Uptake of source water by pumping at a minimum of 200 m\3\/hr;
    (2) Treatment of a minimum of 200 m\3\ of challenge water with the 
BWMS;
    (3) Pumping of a minimum of 200 m\3\ of control water through the 
test facility in a manner that is in all ways identical to paragraph 
(c)(2) of this section, except that the BWMS is not used to treat the 
water;
    (4) Retention of the treated and control water in separate tanks for 
a minimum of 24 hours; and
    (5) Discharge of the treated and control water by pumping.

[[Page 365]]

    (d) The BWMS must be tested in water conditions for which it will be 
approved. For each set of test cycles, a salinity range must be chosen. 
With respect to the salinity of water bodies where the BWMS is intended 
to be used, the challenge water used in the test set-up must have 
dissolved and particulate content as described in the ETV Protocol.
    (e) The approval certificate issued in accordance with Sec.  
162.060-10(g) will list the salinity ranges for which the BWMS is 
approved.
    (f) The BWMS must be tested at its rated capacity or as specified in 
paragraph (f)(1) of this section for each test cycle and must function 
to the manufacturer's specifications during the test.
    (1) Treatment equipment may be downsized for land-based testing, but 
only when the following criteria are met:
    (i) Treatment equipment with a treatment rated capacity (TRC) equal 
to or less than 200 m\3\/h must not be downscaled.
    (ii) Treatment equipment with a TRC greater than 200 m\3\/h but less 
than 1,000 m\3\/h may be downscaled to a maximum of 1:5 scale, but must 
not be less than 200 m\3\/h.
    (iii) Treatment equipment with a TRC equal to or greater than 1,000 
m\3\/h may be downscaled to a maximum of 1:100 scale, but must not be 
less than 200 m\3\/h.
    (iv) The manufacturer of the BWMS must demonstrate by using 
mathematical modeling, computational fluid dynamics modeling, and/or by 
calculations, that any downscaling will not affect the ultimate 
functioning and effectiveness onboard a vessel of the type and size for 
which the BWMS will be approved.
    (2) Greater scaling may be applied and lower flow rates used other 
than those described in paragraph (f)(1) of this section if the 
manufacturer can provide evidence from full-scale shipboard testing, in 
accordance with paragraph (f)(1)(iv) of this section, that greater 
scaling and lower flow rates will not adversely affect the testing's 
ability to predict full-scale compliance with the BWDS. The procedures 
of Sec.  162.060-10(b)(1) of this subpart must be followed before 
scaling of flow rates other than those provided in paragraph (f)(1) of 
this section may be used.
    (g) The test set-up, TRC, and scaling of all tests (including 
mathematical and computational fluid dynamics modeling) must be clearly 
identified in the Experimental Design section of the Test Plan.

exceed those used during land-based tests.
    (2) The circumstances of the vessel's operation during the period of 
shipboard testing provide an acceptable range of geographic and seasonal 
variability conditions.
    (i) The source water used for testing is representative of harbor or 
coastal waters. Testing must include temperate, semi-tropical, or 
tropical locations with ambient organism concentrations that will 
provide a significant challenge to the efficacy of the BWMS.
    (ii) Concentrations of organisms greater than or equal to 50 
micrometers, and organisms less than 50 micrometers and greater than or 
equal to 10 micrometers in the source water must exceed 10 times the 
maximum permitted values in the BWDS.
    (3) The ports that the vessel visits provide adequate availability 
of transportation and scientific support needed to accomplish the 
necessary sampling and analytical procedures during the shipboard tests.
    (f) The vessel's ballast water system must be provided with sampling 
ports arranged in order to collect representative samples of the 
vessel's ballast water. In addition to the sampling ports designed and 
installed in accordance with the specifications in the ETV Protocol 
(incorporated by reference, see Sec.  162.060-5), sampling ports must be 
located--
    (1) As close as practicable to the BWMS prior to treatment to 
determine concentrations of living organisms upon uptake;
    (2) As close as practicable to the BWMS overboard outlet prior to 
the discharge point to determine concentrations of living organisms 
prior to discharge; and
    (3) Elsewhere as necessary to ascertain the proper functioning of 
the BWMS.
    (g) All test results must be reported in accordance with paragraph 
(i) of this section. The efficacy of the BWMS must be confirmed during 
at least five consecutive valid test cycles.
    (1) A test cycle entails--
    (i) The uptake of ballast water by the vessel;
    (ii) The storage of ballast water on the vessel;
    (iii) Treatment of the ballast water by the BWMS, except in control 
tanks, if used, with no fine-tuning or adjustment of the system except 
as specifically detailed in the OMSM; and
    (iv) The discharge of ballast water from the vessel.
    (2) All test cycles must include quantification of the water quality 
parameters on uptake.
    (3) All test cycles must include discharge tests and quantification 
of the concentration of living organisms in the treated ballast water on 
discharge. Sampling and analysis for living organisms will be in 
accordance with the ETV Protocol.
    (4) A test cycle must meet the following criteria in order to be 
considered valid:
    (i) The uptake of the source water must be conducted in accordance 
with paragraph (e)(2)(i) of this section.
    (ii) Source waters must be analyzed for organisms greater than or 
equal to 50 micrometers and organisms less than 50 micrometers and 
greater than or equal to 10 micrometers. To simplify the testing 
program, these source water samples need only be collected and properly 
preserved and transported for counting by trained microscopists in land-
based laboratories. The reported data by taxa (to the lowest reasonably 
identifiable taxonomic grouping) will be used to characterize the source 
water biological test conditions.
    (iii) The BWMS must operate successfully as designed, maintaining 
control of all set points and treatment processes, including any pre-
discharge conditioning to remove or neutralize residual treatment 
chemicals or by-products.
    (iv) All design or required water quality parameters must be met for 
the discharged water.
    (v) Whole effluent toxicity testing must be conducted in accordance 
with the December 2008 Environmental Protection Agency (EPA) Vessel 
General Permit (VGP) requirements (VGP Section 5.8; available at http://
www.epa.gov/npdes/pubs/vessel_vgp_permit.pdf).

of the period of ballast water uptake, as appropriate and practicable 
for the parameters to be measured.
    (ii) Water quality parameters (e.g., dissolved and particulate 
organic material, pH, etc.) that may affect the efficacy of BWMS that 
make use of active substances or other processes, or water quality 
parameters identified by the manufacturer and/or the independent 
laboratory as being critical, must be measured either continuously 
during or at the beginning, middle, and end of the period of ballast 
water uptake, as appropriate and practicable for the parameters to be 
measured.
    (h) Samples of ballast water must be collected from in-line sampling 
ports in accordance with the sampling specifications in the ETV 
Protocol.
    (i) The following information must be documented during the entire 
period of BWMS testing operations conducted on the vessel:
    (1) All ballast water operations, including volumes and locations of 
uptake and discharge.
    (2) All test cycles, even those in which the BWMS failed to meet the 
BWDS, must be documented. The possible reasons for an unsuccessful test 
cycle must be investigated and included in the Test Report.
    (3) All weather conditions and resultant effects on vessel 
orientation and vibration.
    (4) Scheduled maintenance performed on the BWMS.
    (5) Unscheduled maintenance and repair performed on the BWMS.

    (d) Manual. Each pilot hoist must have a manual of installation 
instructions, operating instructions, maintenance and repair 
instructions, a lubrication chart, a parts list, a list of sources of 
repair parts, and a log for keeping maintenance records. Each manual 
must be in English.



Sec.  163.002-21  Approval tests.

    (a) General. If a pilot hoist fails one of the tests in this section 
the cause of the failure must be identified and any needed design 
changes made. After a test failure and any design change, the failed 
test, and any other previously completed tests affected by the change, 
must be rerun.
    (b) Visual examination. Before starting the tests described in this 
section an assembled pilot hoist is examined for evidence of 
noncompliance with the requirements in Sec. Sec.  163.002-11 and 
163.002-13.
    (c) The following approval tests must be conducted:
    (1) Rung strength. If the pilot hoist has a rigid ladder a static 
load of 900 kilograms (2000 pounds) is applied to the center of a ladder 
rung for one minute. The load must be uniformly distributed over a 100 
millimeter (4 inch) wide contact surface. The test must be repeated 
using a second ladder rung. The rungs must not break or crack during 
these tests.
    (2) Platform strength. If the pilot hoist has a lift platform, the 
platform is lifted to a level where it is supported only by its 
suspension components. A static load of 900 kilograms (2000 pounds) is 
then applied to the center of the platform for one minute. The load must 
be uniformly distributed over a 100 millimeter (4 inch) square contact 
surface. The test must be repeated enough additional times so that the 
load is placed in the center of each hatch cover when in its closed 
position, and in the center of each area of the platform located between 
floor supports. The platform must not break or crack during these tests.
    (3) Deck interlock. If the pilot hoist is portable, it is placed in 
an uninstalled position. Its hoist control lever is then activated. The 
deck interlock must prevent movement of the ladder or lift platform when 
the lever is activated.
    (4) Lifting and lowering speed and level wind. The hoist is 
installed in a level operating position and a weight equal to the weight 
of the pilot ladder plus 150 kg (330 lb.) times the maximum persons 
capacity of the hoist is placed on its ladder or lift platform. The 
ladder or lift platform is repeatedly raised and lowered under power 
operation until a total distance of at least 150 meters (500 feet) has 
been traversed. The ladder or lift platform is raised and lowered each 
time through a distance of at least 5 meters (16 feet). The average 
speed of raising the ladder or lift platform and the average lowering 
speed during this test must both be between 15 and 21 meters per minute 
(50 and 70 feet per minute). During the test, each suspension cable must 
have one level wind of wrap each time it is rewound onto its drum.
    (5) Upper position stop. The hoist is installed in a level operating 
position

[[Page 382]]

and a weight equal to the weight of the pilot ladder plus 150 kg (330 
lb.) times the maximum persons capacity is attached to the hoist. The 
hoist must be able to raise the weight to the upper limit of travel of 
the ladder or lift platform and must be able to stop at the upper limit 
without jarring, jerking, or damage. The test is repeated with no weight 
on the ladder or lift platform.
    (6) Cable securing device. If the hoist has suspension cables, it is 
installed in a level operating position and the cables are run all the 
way out. A weight equal to 2.2 times the working load is then attached 
to the cables. The cables must remain securely attached to the drums for 
at least one minute after the weight has been attached.
    (7) Controls and power indicator. The hoist is installed in a level 
operating position and a weight equal to the working load is attached to 
the hoist. The hoist control lever is then operated with the power both 
on and off. The lever, when operated, must meet the requirements in 
Sec.  163.002-13(l). The power indicator must meet the requirements in 
Sec.  163.002-13(n) during the test. When the power is turned off, the 
ladder or lift platform must stop immediately and remain stationary 
until power is turned on. The emergency stop switch on the ladder or 
lift platform is activated at some point when the ladder or lift 
platform is being raised or lowered. Upon activation, the ladder or lift 
platform must stop and remain stationary.
    (8) Hand operation and interlock. The hoist is installed in a level 
operating position and a weight equal to the working load is attached to 
the hoist. The hand operated device is then engaged. One person, when 
using the hand operated device, must be able to raise and lower the 
weight through a distance of at least 5 meters (16 ft.) in each 
direction and must be able to raise and lower it at a speed of at least 
1.5 meters per minute (5 ft. per minute). When raising or lowering the 
hoist with the hand operated device, the power source for the hoist is 
turned on, or an attempt is made to turn it on. Then, with power source 
turned off, the hand operated device is disengaged. The power source is 
then turned on and an attempt made to engage the hand operated device. 
The interlock must prevent simultaneous operation of the power source 
and the hand operated device.
    (9) 2.2x overload. The hoist is installed in a level operating 
position. Each roller on the ladder or lift platform is placed in 
contact with a vertical surface. A weight equal to the difference 
between 2.2 times the working load and the weight of the ladder or lift 
platform is placed on the ladder or lift platform. The ladder or lift 
platform is raised through a distance of at least 5 meters (16 feet) and 
the hoist control lever is then released. The ladder or lift platform 
must stop without jarring or damage and must hold the weight for at 
least one minute. The weight is then lowered through a distance of not 
less than 5 meters (16 feet) and the control lever is then released. The 
ladder or lift platform must stop within 600 millimeters (2 ft.) of 
where the hoist was when the lever was released and the ladder or lift 
platform must remain stationary for at least one minute thereafter. Each 
roller must move smoothly over the vertical surface without jamming or 
sliding during the test.
    (10) 6x overload. The hoist is installed in a level operating 
position. A load of six times the working load is attached to the hoist. 
(If the hoist has suspension cables, the cables must be run out at least 
one meter (3 ft.) before adding the load to the hoist). The weight must 
remain stationary for at least one minute without damage to any part of 
the hoist. The test is repeated simulating a vessel list of 15 degrees 
toward the side on which the hoist is installed.
    (11) Level wind suspension cable. If the hoist has suspension 
cables, it is installed in a level operating position with the cables 
wound onto the drums. A weight equal to the working load is attached to 
the hoist. The cables are run all the way out and then rewound back onto 
the drums at least ten times. Each drum and cable is observed for level 
winding as the cable is wound onto the drum. The test must be repeated 
with a weight equal to the weight of the rigid ladder or lift platform. 
In each test, each cable must always rewind onto the drum in one level 
wind of wrap.

[[Page 383]]

    (12) Rung friction test. One rung of each type used on a rigid 
ladder must be subjected to this test. This test compares the dry and 
wet surface friction characteristics of ladder rungs with those of a 
standard oak step.
    (i) The standard step must have a surface of clean oak that meets 
Sec.  163.003-11(b) of this chapter and that is 115 mm (4\1/2\ in.) wide 
by 400 mm (16 in.) long. The stepping surface must have grooves that are 
3 mm (\1/8\ in.) deep and 3 mm wide. The grooves must run in two 
different directions at right angles to each other, and at 45 degree 
angles with each edge of the stepping surface, so that the grooves form 
a diamond pattern covering the stepping surface. The centers of all 
parallel grooves must be 13 mm (\1/2\ in.) apart.
    (ii) The standard step must be set in a level position. A metal 
block must be placed on one end of the step so that the block is in 
contact with the stepping surface. The metal block must weigh between 
1.5 kg (3.3 lb.) and 3.0 kg (6.6 lb.) and must not be more than 100 mm 
(4 in.) wide by 135 mm (5\3/8\ in.) long. The surface of the block in 
contact with the step must have leather or composition shoe sole 
material attached to it.
    (iii) The end of the step that has the metal block on it must be 
slowly raised until the block starts to slide. The angle of the step in 
this position must be measured and recorded. The step and block must 
then be placed under water and the procedure repeated.
    (iv) The procedure in paragraph (c)(12)(iii) of this section must be 
repeated using a rigid ladder rung in place of the standard step.
    (v) The ladder rung must then be secured in a horizontal position 
with a block resting on its stepping surface. The block must be of a 
size similar to the one used in the previous tests and have the same 
shoe sole surface used in the previous tests. The block must be arranged 
to apply a vertical load of 40 kg (88 lb.) to the rung. The block must 
be then moved back and forth in the same line from one end of the 
stepping surface to the other. This must be done for a total of 1,500 
cycles.
    (vi) The rung must again be tested as described in paragraph 
(c)(12)(iii) of this section, except that the initial position of the 
block must be on a part of the stepping surface that was subjected to 
the 1,500 cycles of rubbing.
    (vii) The angles at which the block starts to slide on a wet and dry 
ladder rung when tested under paragraphs (c)(12)(iv) and (c)(12)(vi) of 
this section must be equal to or greater than the corresponding angles 
measured for the standard step when tested under paragraph (c)(12)(iii) 
of this section.

member.
    (b) Suspension member. The suspension members of a pilot ladder must 
meet the following requirements:
    (1) Each suspension member must be continuous from the top of the 
ladder to the bottom and must not be painted or otherwise coated or 
covered.
    (2) Except as provided in paragraph (g) of this section--
    (i) The top end of one suspension member on each side of the ladder 
must extend at least 3 m (10 ft.) beyond the top ladder step; and
    (ii) The top ends of the other suspension members must be just above 
the top step and must have an eye splice or thimble large enough to fit 
two passes of a suspension member.

splice or thimble must be served or treated to prevent fraying.
    (4) Each pair of suspension members must be clamped together both 
above

[[Page 385]]

and below each step. Marline seizing may not be used.
    (5) The clear space between the suspension members on one side of a 
ladder and those on the other side must be at least 400 mm (16 in.), but 
not more than 480 mm (19 in.).
    (6) The suspension members must not have fittings at the bottom of 
the ladder that can be used for attaching additional ladder sections.
    (c) Steps. Pilot ladder steps must meet the following requirements:
    (1) The four lowest steps must be molded steps and the rest of the 
steps must be either wooden or molded steps.
    (2) The top face of each step must have a rectangular surface that 
is at least 115 mm (4\1/2\ in.) wide with a non-skid surface that does 
not retain water. Adhesive non-skid sheets may not be used. (For 
example, a suitable surface for a step is one that has grooves at least 
3 mm (\1/8\ in.) deep cut in a diamond pattern so that water runs off 
the edge of the step. Non-skid grit is applied directly to the step 
surface extending to almost the full width of the step.)
    (3) Each step at its thinnest point must be at least 25 mm (1 in.) 
thick and in determining this thickness, the depth of the grooves in the 
non-skid surface and the diameter of any hole extending from one side of 
the step to the other must not be counted.
    (4) Each step must be at least 480 mm (19 in.) long.
    (5) Each step must be designed so that it can be removed and 
replaced without unstringing the ladder. If special replacement steps 
are made to meet this requirement, the replacement steps must meet the 
requirements of this section.
    (6) If a step has grooves for its suspension members, the grooves 
must be in the sides of the steps.
    (7) The spacing from the top of one step to the top of the next step 
must be uniform and this spacing must be between 300 mm (12 in.) and 350

    (8) Each step must be a bright orange color, except that this color 
is not required for the non-skid surface. If a step is painted, it must 
be painted with a two-part epoxy paint intended for marine use, or a 
paint of equivalent durability.
    (9) The height of each device attached to the step for securing the 
suspension members must not be more than one-half the width of the step 
so that the step is not prevented from rolling if the ladder is caught 
between a pilot boat and the hull of the vessel.
    (10) Each replacement step must be either white or yellow instead of 
the orange color required under paragraph (c)(8) of this section, and 
must have the special marking required in Sec.  163.003-25(b).
    (d) Spreaders. Each pilot ladder with 5 or more steps must have one

the vessel's side.
    (d) Each step must be arranged so that it can bear on the side of 
the vessel when the ladder is in use.



Sec.  163.003-17  Strength.

    (a) Each pilot ladder must be designed to pass the approval tests in 
Sec.  163.003-21.
    (b) [Reserved]



Sec.  163.003-21  Approval tests.

    (a) General. Each approval test must be conducted on a ladder of the 
longest length for which approval has been requested. If the ladder 
fails one of the tests, the cause of the failure must be identified and 
any needed design changes made. After a test failure and any design 
change, the failed test, and any other previously completed tests 
affected by the change, must be rerun. Any ladder step that has a 
residual deflection after testing under this section may not be used 
thereafter in any ladder represented as Coast Guard approved.
    (b) Visual examination. Before starting the approval tests, an 
assembled pilot ladder is examined for evidence of noncompliance with 
the requirements in Sec. Sec.  163.003-11, 163.003-13, and 163.003-15.
    (c) The following approval tests must be conducted:
    (1) Step flexibility test. This test is performed on six different 
steps, one of which must be a molded step and one of which must be a 
replacement step if special replacement steps are made by the 
manufacturer. Each step is placed on a pair of supports located at the 
points where the step would ordinarily be attached to the suspension 
members. A static load must be applied uniformly for a period of at 
least one minute over a contact surface that is at the center of the 
step and is approximately 100 mm (4 in.) wide. The load must be 150 kg 
(330 lb.) for each molded step that is used only as one of the four 
bottom steps in the ladder. The load must be 320 kg (700 lb.) for each 
other step. The deflection of the step is measured while the step is 
under load and after the load is removed. The step must not deflect more 
than 20 mm (\3/4\ in.) under the load, and there must be no residual 
deflection after the load is removed.
    (2) Strength test 1. An assembled ladder is supported so that a 
static load, if placed on any of its steps, would exert a force on both 
the step and each suspension member. A static load of 900 kg (2,000 lb.) 
is then placed on one step for at least one minute. The load must be 
uniformly distributed over a contact surface that is approximately 100 
mm (4 in.) wide. The center of the contact surface must be at the center 
of the step. This test is performed on six different steps, one of which 
must be a molded step. None of the steps may break or crack. No 
attachment between any step and a suspension member may loosen or break 
during this test.
    (3) Strength test 2. An assembled ladder is suspended vertically to 
its full length. A static load of 900 kg (2,000 lb.) is then applied to 
the bottom step of the ladder so that it is distributed equally between 
the suspension members. The suspension members, and inserts must not 
break, incur any elongation or deformation that remains after the test 
load is removed, or be damaged in any other way during this test.
    (4) Strength test 3. A rolled up ladder is attached to anchoring 
fixtures in a location away from any wall or structure that would 
prevent it from falling freely, and where it can hang to its full length 
vertically. The ladder when dropped must unroll freely. When unrolling 
the ladder, its steps and attachments must not become cracked, broken, 
or loosened. Other similar damage making the ladder unsafe to use must 
likewise not occur.
    (5) Step friction test. One step of each type used on a pilot ladder 
must be subjected to this test. This test compares the dry and wet 
surface friction characteristics of ladder steps with those of a 
standard oak step.
    (i) The standard step must have a surface of clean oak that meets S/
163.003-11(b) and that is 115 mm (4\1/2\ in.) wide by 400 mm (16 in.) 
long. The stepping surface must have grooves that are 3 mm (\1/8\ in.) 
deep and 3 mm wide. The grooves must run in two different

[[Page 387]]

directions at right angles to each other, and at 45 degree angles with 
each edge of the stepping surface, so that the grooves form a diamond 
pattern covering the stepping surface. The centers of all parallel 
grooves must be 13 mm (\1/2\ in.) apart.
    (ii) The standard step must be set in a level position. A metal 
block must be placed on one end of the step so that the block is in 
contact with the stepping surface. The metal block must weigh between 
1.5 kg (3.3 lb.) and 3.0 kg (6.6 lb.) and must not be more than 100 mm 
(4 in.) wide by 135 mm (5\3/8\ in.) long. The surface of the block in 
contact with the step must have leather or composition shoe sole 
material attached to it.
    (iii) The end of the step that has the metal block on it must be 
slowly raised until the block starts to slide. The angle of the step in 
this position must be measured and recorded. The step and block must 
then be placed under water and the procedure repeated.
    (iv) The procedure in paragraph (c)(6)(iii) of this section must be 
repeated using a pilot ladder step in place of the standard step.
    (v) The ladder step must then be secured in a horizontal position 
with a block resting on its stepping surface. The block must be of a 
size similar to the one used in the previous tests and have the same 
shoe sole surface used in the previous tests. The block must be arranged 
to apply a vertical load of 40 kg (88 lb.) to the step. The block must 
be then moved back and forth in the same line from one end of the 
stepping surface to the other. This must be done for a total of 1,500 
cycles.
    (vi) The step must again be tested as described in paragraph 
(c)(6)(iii) of this section, except that the initial position of the 
block must be on a part of the stepping surface that was subjected to 
the 1,500 cycles of rubbing.
    (vii) The angles at which the block starts to slide on a wet and dry 
ladder step when tested under paragraphs (c)(6)(iv) and (c)(6)(vi) of 
this section must be equal to or greater than the corresponding angles 
measured for the standard step when tested under paragraph (c)(6)(iii) 
of this section.



Sec.  163.003-25  Marking.

    (a) Each pilot ladder step manufactured under Coast Guard approval 
must be branded or otherwise permanently and legibly marked on the 
bottom with--
    (1) The name of the manufacturer;
    (2) The manufacturer's brand or model designation;
    (3) The lot number or date of manufacture; and
    (4) The Coast Guard approval number.
    (b) In addition to the markings required under paragraph (a) of this 
section each step sold as a replacement step must be branded or 
otherwise permanently and legibly marked with the words ``REPLACEMENT 
STEP ONLY.''

[CGD 74-140, 46 FR 63291, Dec. 31, 1981, as amended by CGD 79-032, 49 FR 
25456, June 21, 1984]



Sec.  163.003-27  Production tests and examination.

    (a) General. Each ladder produced under Coast Guard approval must be 
tested in accordance with this section and subpart 159.007 of this 
chapter. Steps that fail testing may not be marked with the Coast Guard 
approval number and each assembled ladder that fails testing may not be 
sold as Coast Guard approved.
    (b) Test No. 1: Steps. Steps must be separated into lots of 100 
steps or less. Steps of different types must be placed in separate lots. 
One step from each lot must be selected at random and tested as 
described in Sec.  163.003-21(c)(2) except that supports are placed 
under the step at the points where it would be attached to suspension 
members in an assembled ladder. If the step fails the test, ten more 
steps must be selected at random from the lot and tested. If one or more 
of the ten steps fails the test, each step in the lot must be tested. No 
step that has any residual deflection after the test may be used in a 
ladder represented by the manufacturer as Coast Guard approved.
    (c) Test No. 2: Ladders. Assembled ladders must be separated into 
lots of 20 ladders or less. One ladder must be selected at random from 
the ladders in each lot. The ladder selected must be at least 3 m (10 
ft.) long or, if each ladder in the lot is less than 3 m long, a

[[Page 388]]

ladder of the longest length in the lot must be selected. The ladder 
must be tested as prescribed in Sec.  163.003-21(c)(3) except that only 
a 3 m section of the ladder need be subjected to the static load. If the 
ladder fails the test, each other ladder in the lot must be tested.
    (d) Independent laboratory. Each production test must be conducted 
or supervised by an independent laboratory. However, if a test is 
performed more than 4 different times per year, laboratory participation 
is required only 4 times per year. If the laboratory does not 
participate in all tests, the times of laboratory participation must be 
as selected by the laboratory. The times selected must provide for 
effective monitoring throughout the production schedule.
    (e) Visual examination. The visual examination described in Sec.  
163.003-21(b) must be conducted as a part of each production test.

Sec.  164.003-1  Applicable specifications.

    (a) There are no other specifications applicable to this subpart.
    (b) [Reserved]



Sec.  164.003-2  Grades.

    (a) Processed kapok shall be of but one grade as in this subpart.
    (b) [Reserved]



Sec.  164.003-3  Material and workmanship.

    (a) The raw kapok fiber shall be long, clean, creamy white in color, 
lustrous, free from discoloration and adulteration with other fiber, and 
of a quality equal to that grown in Java.
    (b) Kapok shall be processed by teasing in a machine using the air-
blow method. Mechanical separation of fiber masses is permitted, but

Sept. 29, 2014]



Sec.  164.003-4  Inspections and tests.

    (a) Kapok fibers to be used in a finished product subject to 
inspection by the Coast Guard shall be subject to inspection and tests 
at the plant of the manufacturer of such product, who shall furnish the 
necessary testing tank, test cages, and scales.
    (b) Acceptance of kapok prior to being incorporated into finished 
products, or during the course of manufacture, shall in no case be 
construed as a guarantee of the acceptance of the finished product.
    (c) Not less than a one-pound sample from each 1,000 pounds of kapok 
shall be tested for buoyancy by the inspector. At his discretion, the 
inspector may select additional samples for tests if deemed advisable.
    (d) The buoyancy test shall be made with 16 ounces of processed 
kapok uniformly packed in a rigid wire box or cage with metal reinforced 
edges, and submerged by weights in a tank of fresh water to a depth of 
12 inches below the surface of the water, measurement made to the top of 
box, for 48 hours. The test box shall be cylindrical in shape, and as 
nearly as practicable \1/3\ cubic foot in volume, 4 inches deep, 13.54 
inches diameter, all inside measurements; constructed of about 0.065 
inch galvanized iron wire with about \1/4\ inch mesh, and lined with 
about 0.007 inch copper wire screen about 18 meshes to the inch, to 
prevent the kapok from pushing out through the larger wire meshes. At 
the end of forty-eight hours submergence, the buoyancy shall be 
determined by subtracting the submerged weight of the box, accessory 
weights and kapok from the submerged weight of the box and weights 
without the kapok, and dividing the remainder by the volume of the kapok 
expressed in cubic feet.
    (e) Kapok fiber shall, at the option of the inspector, be subjected 
to a microscopic examination to detect adulteration with other fiber.
    (f) Processed kapok shall, at the option of the inspector, be 
subjected to separation of kapok fibers from foreign matter by hand, the 
portions of each weighed, and percentage of foreign matter computed for 
compliance with Sec.  164.003-3(d).



Sec.  164.003-5  Procedure for approval.

    (a) Processed kapok is not subject to formal approval, but will be 
accepted by the inspector on the basis of this subpart for use in the 
manufacture of lifesaving equipment utilizing it.
    (b) [Reserved]

    Source: CGFR 53-25, 18 FR 7874, Dec. 5, 1953, unless otherwise 
noted.



Sec.  164.006-1  Applicable specifications.

    (a) There are no other specifications applicable to this subpart.
    (b) [Reserved]



Sec.  164.006-2  Grades.

    (a) Deck coverings shall be of but one grade as specified in this 
subpart, and shall be known as ``an approved deck covering.''
    (b) [Reserved]



Sec.  164.006-3  Construction, materials, and workmanship.

    (a) It is the intent of this specification to obtain a deck covering 
made largely of incombustible materials with low heat transmission 
qualities which will produce a minimum of smoke when exposed to high 
temperatures.
    (b) Deck coverings shall be of such a quality as to successfully 
pass all of the tests set forth in Sec.  164.006-4.



Sec.  164.006-4  Inspection and testing.

    (a) All tests shall be conducted at the National Bureau of Standards 
or other

[[Page 392]]

laboratories designated by the Coast Guard.
    (b) Smoke tests. (1) A sample of each thickness submitted shall be 
tested for smoke emission. Each sample shall be laid on a \1/
4\ x 12 x 27 steel plate. Normal 
protective coatings and deck attachments shall be incorporated in the 
samples. Each sample shall be heated in a furnace whose temperature is 
limited to the standard decking curve reaching 1,325 degrees F. at the 
end of one hour. Smoke observations shall be made at intervals not 
greater than five minutes during the one-hour period of test.
    (2) Instantaneous values of the percent of light transmission shall 
be calculated from the observations noted in paragraph (b)(1) of this 
section. A plot of light transmission values shall be made using 
straight lines between instantaneous values.
    (3) Any instantaneous value of 10 percent light transmission or less 
shall be considered sufficient cause for rejection of a deck covering.
    (4) Average values of light transmission shall be calculated for 15, 
30, and 60 minutes. Averages shall be an arithmetic mean with values 
taken at one minute intervals from the plotted curve noted in paragraph 
(b)(2) of this section. If any of the three average values of light 
transmission is less than the values set forth below, it will be 
considered sufficient cause for rejection of a deck covering:

15 minutes--90 percent light transmission.
30 minutes--60 percent light transmission.
60 minutes--50 percent light transmission.

    (c) Fire resistance and integrity tests. (1) A sample of each 
thickness submitted shall be tested for fire resistance and integrity. 
Each sample shall be laid on a \1/4\ x 12 x 
27 steel plate. Normal protective coatings and deck 
attachments shall be incorporated in the samples. Each sample shall be 
heated in a furnace whose temperature is controlled according to the 
standard fire exposure curve reaching 1,700 degrees F. at the end of one 
hour. Temperature of the unexposed side as indicated by a thermocouple 
under a 0.40 inch asbestos pad shall be observed at intervals not 
greater than 5 minutes during the one-hour period of test.
    (2) Data from these tests shall be analyzed to determine the 
thicknesses necessary to limit the average temperature rise on the 
unexposed surface to 250 degrees F. above the original temperature at 
the end of 15, 30, and 60 minutes.
    (3) Excessive cracking, buckling, or disintegration may be 
considered cause for rejection.
    (d) Organic carbon content test. (1) The organic carbon content 
shall be determined and shall not exceed 0.12 gram per cubic centimeter 
of the molded deck covering.
    (e) Spot check tests. (1) Deck coverings are not inspected at 
regularly scheduled factory inspections; however, the cognizant Officer 
in Charge, Marine Inspection, may detail a marine inspector at any time 
to visit any place where deck coverings are manufactured to conduct any 
inspections or examinations deemed advisable and to select 
representative samples for further examination, inspection or tests. The 
marine inspector shall be admitted to any place where work is done on 
deck coverings or component materials.
    (2) Manufacturers of approved deck coverings shall maintain quality 
control of materials used, manufacturing methods, and the finished 
product so as to meet the requirements of this specification, and any 
other conditions outlined on the certificate of approval, but the Coast 
Guard also reserves the right to make spot-check tests of approved deck 
coverings at any time on samples selected by a marine inspector at the 
place of manufacture or samples obtained from other sources in the 
field. The manufacturer will incur no expense for such tests, but the 
results shall be binding upon the approval of his product. The 
manufacturer will be advised in advance of the time of testing of the 
samples selected and may witness the tests if he so desires.

Sec.  164.007-2  Purpose.

    The purpose of this specification is to set forth tests necessary to 
measure the insulation value of structural insulation specimens under 
fire exposure conditions. The tests are not intended to measure the 
integrity of structural components of an assembly Insulation meeting 
this specification is adequate to limit the average temperature rise of 
a steel bulkhead to 139 [deg]C. (250 [deg]F.) at the end of a 60-minute 
standard fire test.



Sec.  164.007-3  Conditions of approval.

    (a) Structural insulation shall be of such quality as to 
successfully meet the requirements for an incombustible material as set 
forth in subpart 164.009 of this part.
    (b) Structural insulation shall be of such quality and thickness as 
to successfully pass all of the tests set forth in Sec.  164.007-4, and 
the retests required by Sec.  164.007-8.
    (c) The product shall be so marked as to be readily identifiable to 
an inspector in the field. The marking shall include the Coast Guard 
approval number.



Sec.  164.007-4  Testing procedure.

    (a) Tests. All tests, including the retests, shall be conducted at 
the National Bureau of Standards or other laboratories designated by the 
Coast Guard.
    (b) Test of physical properties. (1) Density measurement: The 
smallest sample for density measurements of solid materials shall be 30 
cm x 30 cm (12 x 12) by the submitted thickness. 
Length and width measurements shall be made to the nearest 1 mm. (\1/
32\), thickness to the nearest 0.25 mm. (0.01), 
allowance being made of any nonflatness of the major surfaces of the 
specimen. Measurements of dimensions of fibrous insulations shall be 
made to the nearest 1.5 mm. (\1/16\) on a nominal 30 cm. 
(12) cube assembled from sheets of thickness as received. The 
average of at least four measurements of each dimension shall be 
reported. The weight shall be determined with a scale or balance 
sensitive and accurate to 0.5 percent or less of the total weight. The 
dimensional and weight measurements shall not be made until the sample 
has been conditioned 1 week, or longer if required to reach constant 
weight, in an atmosphere at 23[deg] 1 [deg]C. (73 
[deg]F. 2[deg]) and 50 percent relative humidity.
    (2) Transfer to a previously dried and weighed wide-mouth weighing 
bottle provided with a glass stopper. Remove the stopper and heat the 
bottle and sample at 105[deg] 5 [deg]C. (221[deg] 
9 [deg]F.) for 4 hours, insert the stopper, cool 
and weigh. Calculate the content of moisture and other volatiles as 
percent of the final dry weight of the sample.
    (c) Preparation of fire test specimens. (1) The fire test specimens 
shall be conditioned to approximately constant weight with air being 
maintained at a relative humidity of 40 to 70 percent and a temperature 
of 15[deg] to 25 [deg]C. (50[deg] to 77 [deg]F.). After conditioning, 
but before testing, the temperature of the specimens shall not exceed 40 
[deg]C. (104 [deg]F.).
    (2) Representative samples of the structural insulation, of a 
thickness or thicknesses and density as specified in Sec.  164.007-
9(a)(5), shall be tested as part of an assembly which forms a portion of 
a vertical wall of a furnace. The assembly shall be at least 100 cm. x 
150 cm. (40 x 60) in size. More than one sample 
may be tested, see Sec.  164.007-7.
    (3) The specimens shall be attached to a 5 0.3 
mm. (\3/16\) thick steel plate and mounted in the furnace 
with the steel plate forming the exterior wall of the furnace. Any 
stiffening members on the steel plate shall be installed on the face not 
adjacent to the insulation. Spacer strips of asbestos cement board or 
similar material, up to 5 cm. (2) in width, shall be 
installed around the periphery of the panel. For fibrous insulations, 
the attachment to the steel plate shall be made by means of 5 mm. 
(0.19) diameter steel pins on 30 cm. (12) centers 
covered by 18-gage, 4 cm. (1\1/2\) mesh expanded metal. 
Alternate methods will be given consideration.

[[Page 395]]

For other materials, typical installation practice shall be used.
    (d) Furnace control. (1) The furnace temperature shall be determined 
by at least four mineral insulated thermocouples having rapid response, 
and distributed so as to represent fairly the furnace temperature and to 
insure as uniform heating as possible. The thermocouples shall be 
arranged so that the hot junction is approximately 10 cm. from the 
nearest point of the specimen.
    (2) The furnace temperature shall be continuously controlled so as 
to follow the standard time-temperature curve within the accuracy 
specified in paragraph (d)(4) of this section.
    (3) The standard time-temperature curve is defined by a smooth curve 
drawn through the following points:

At the beginning of the test, 20 [deg]C. (68 [deg]F.)
At the end of the first 5 minutes, 538 [deg]C. (1,000 [deg]F.).
At the end of the first 10 minutes, 704 [deg]C. (1,300 [deg]F.).
At the end of the first 30 minutes, 843 [deg]C. (1,550 [deg]F.).
At the end of the first 60 minutes, 927 [deg]C. (1,700 [deg]F.).


For a further definition of the time-temperature curve, see Appendix I 
of the ASTM Standard E-119, ``Fire Tests of Building Construction and 
Materials''.
    (4) The accuracy of the furnace control shall be such that the area 
under the mean time-temperature curve is within 15 percent of the area 
under the standard time-temperature curve during the first 10 minutes of 
the test, within 10 percent during the first one-half hour, and within 5 
percent for any period after the first one-half hour. At any time after 
the first 10 minutes of the test the mean furnace temperature shall not 
differ from the standard curve by more than 100 [deg]C. (180 [deg]F.). 
Consideration will be given to adjusting the results for variation of 
the furnace exposure from that prescribed. If corrections are made, they 
shall be in accordance with the procedures set forth in the ASTM E-119.
    (e) Temperature of unexposed surface. For the unexposed surface 
temperature measurement a thermocouple of 0.5 mm. (0.020) 
diameter wires shall be soldered centrally with high temperature solder 
to one surface of a disc of copper 12 mm. in diameter and 0.2 mm. thick. 
The discs shall be covered with an oven-dry asbestos pad 50 mm. x 50 mm, 
and 4 mm. thick. The disc and the pad may be fixed to the surface of the 
steel plate by pins, tape, or a suitable adhesive. The asbestos pad 
shall have a density of approximately 1,000 kg./m.\3\ and thermal 
conductivity of 0.11 kcal/m/hr. x [deg]C. at 100 [deg]C. (212 [deg]F.).
    (f) Temperature observations. (1) All observations shall be taken at 
intervals not exceeding 5 minutes. The surface temperature on the 
exterior side of the steel plate shall be measured by thermocouples 
located as follows:
    (i) One thermocouple located approximately in the center of each 
quadrant of the steel plate (four thermocouples total).
    (ii) One thermocouple close to the center of the steel plate.
    (iii) One thermocouple in way of or as close as possible to one of 
the pins or other through metallic connections (if any) used for holding 
the insulation in place.
    (iv) Further thermocouples at the discretion of the testing 
laboratory or Coast Guard for the purpose of determining the temperature 
at points deemed likely to give a greater temperature rise than any of 
the above-mentioned thermocouples.
    (2) The average temperature rise on the unexposed surface shall be 
obtained by averaging the readings of the thermocouples mentioned in 
paragraphs (f)(1) (i) and (ii) of this section.
    (g) Other observations. Throughout the test observations shall be 
made of all changes and occurrences, which are not criteria of 
performance, but which may create hazard in case of a fire; for example 
the emission of appreciable volumes of smoke or noxious vapors from the 
unexposed side of the test specimen. The specimen shall be examined 
after the test for changes that have taken place and the information 
shall be noted in the test report.
    (h) Duration of testing. The test shall be continued for at least 
one hour or until the maximum surface temperature rise values noted in 
Sec.  164.007-5(a) have been reached, whichever occurs later.

[[Page 396]]



Sec.  164.007-5  Test requirements.

    The insulation value of the specimens for the full scale test shall

    (a) Manufacturers of approved structural insulation shall maintain 
quality control of materials used, manufacturing methods, and the 
finished product utilizing appropriate quality control testing so as to 
meet the requirements of this specification, and any other conditions 
outlined on the certificate of approval. Structural insulation materials 
are not inspected at regularly scheduled factory inspections; however, 
approved materials are subject to retest for continued compliance with 
the requirements of this subpart on the following basis:
    (1) The Coast Guard may detail a marine inspector or other Coast 
Guard designated inspector at any time to visit any place where 
structural insulation is manufactured to conduct any inspections or 
examinations deemed advisable and to select representative samples for 
further examination, inspection, or tests. The inspector shall be 
admitted to any place where work is done on structural insulation or 
component materials.
    (2) At a frequency of not less than once every 5 years following 
issuance of approval, samples of an approved material selected from 
production stock shall be forwarded by the inspector to the Commandant 
for testing in accordance with the requirements of this subpart. Where 
the plant is outside the jurisdiction of a Coast Guard District 
Commander, the frequency of such testing shall be once every 2 years. 
The cost of such testing shall be borne by the manufacturer. The nature 
of the product or its production may dictate a differing retest 
frequency.

[[Page 397]]

    (3) The Coast Guard reserves the right to make spot-check tests of 
approved structural insulation at any time on samples selected by a 
marine inspector obtained during installation on a vessel. The 
manufacturer will incur no expense for such tests, but the results, 
shall be binding upon the approval of his product.
    (b) A small scale furnace test (2[foot] x 2[foot] furnace test 60 
cm. x 60 cm.) shall be conducted. The time of failure shall not vary 
from the original small scale test values by more than 10 percent. In 
addition tests shall be conducted to determine incombustibility (Sec.  
164.009), density and thickness. Values of retesting for density and 
thickness shall not vary from the original test values by more than 10 
percent.

by Sec.  164.008-6.



Sec.  164.008-3  Testing procedure.

    (a) Tests. All tests, including the retests, shall be conducted at 
the National Bureau of Standards or other laboratories designated by the 
Coast Guard.
    (b) Preparation of test specimen. (1) The test specimens shall be 
conditioned to approximately constant weight with the air being 
maintained at a relative humidity of 40 to 70 percent and a temperature 
of 15[deg] to 25 [deg]C. (59[deg] to 77 [deg]F.). After conditioning, 
but before testing, the temperature of the specimen should not exceed 40 
[deg]C. (104 [deg]F.).
    (2) The specimens shall be mounted in the furnace in a vertical 
position in such a way as to give an exposed surface of at least 4.65 
square meters (50 square feet) and a height of at least 2.44 meters (8 
feet).
    (3) The specimen shall be supported at the top and secured on the 
vertical sides and at the bottom in a manner representative of 
conditions in service. If provision for movement at the edges of a 
bulkhead panel is made for a particular construction in service, the 
specimen should stimulate these conditions.
    (4) The method of securing shall be such that there is no 
possibility of misinterpretation of test results due to the passage of 
flame at the edges of the specimen when the method of fixing is not the 
subject of the test.
    (c) Furnace control. (1) The furnace temperature shall be determined 
by at least four mineral insulated thermocouples having rapid response 
and distributed so as to represent fairly the furnace temperature and to 
insure as uniform heating as possible. The thermocouples shall be 
arranged so that the hot junction is approximately 10 cm. (4) 
from the nearest point of the specimen.
    (2) The furnace temperature shall be continuously controlled so as 
to follow the standard time-temperature curve within the accuracy 
specified in paragraph (c)(4) of this section.
    (3) The standard time-temperature curve is defined by a smooth curve 
drawn through the following points:

At the beginning of the test, 20 [deg]C. (68 [deg]F.).
At the end of the first 5 minutes, 538 [deg]C. (1,000 [deg]F.).
At the end of the first 10 minutes, 704 [deg]C. (1,300 [deg]F.).
At the end of the first 30 minutes, 843 [deg]C. (1,550 [deg]F.).
At the end of the first 60 minutes, 927 [deg]C. (1,700 [deg]F.).


For a further definition of the time-temperature curve, see Appendix I 
of the ASTM Standard E119, ``Fire Tests of Building Construction and 
Materials''.
    (4) The accuracy of the furnace control shall be such that the area 
under the mean time-temperature curve is within 15 percent of the area 
under the standard curve during the first 10 minutes of the test, within 
10 percent during the first one-half hour, and within 5 percent for any 
period after the first one-half hour. At any time after the first 10 
minutes of the test the mean furnace temperature shall not differ from 
the standard curve by more than 100 [deg]C. (180 [deg]F.). Consideration 
will be

[[Page 400]]

given to adjusting the results for variation of the furnace exposure 
from that prescribed. If corrections are made, they shall be in 
accordance with the procedures set forth in ASTM E-119.
    (5) The pressure in the furnace shall be equal to that in the 
laboratory at about one-third of the height of the specimen.
    (d) Temperature of unexposed surface. For the unexposed surface 
temperature measurement, a thermocouple of 0.5 mm. (0.020) 
diameter wires shall be soldered centrally with high temperature solder 
to one surface of a disc of copper 12 mm. diameter and 0.2 mm. thick. 
The discs shall be covered with an oven-dry asbestos pad 50 mm. x 50 mm. 
and 4 mm. thick. The disc and the pad may be fixed to the surface of the 
specimen by pins, tape or a suitable adhesive, depending on the nature 
of the specimen material. The asbestos pad shall have a density of 
approximately 1,000 kg./m.\3\ and thermal conductivity of 0.11 kcal./m./
hr. x C. at 100 [deg]C. (212 [deg]F.).
    (e) Flame penetration. (1) Where cracks or openings are formed 
during the test, an ignition test as prescribed in Sec.  164.008-4(b) 
shall take place immediately after the appearance of cracks or damage, 
followed by similar tests at frequent intervals. The purpose of the test 
is to indicate whether cracks and openings formed during the test are 
such that they would lead to passage of flame.
    (2) The cotton wool used for the tests prescribed in Sec.  164.008-
4(b) shall consist of new undyed soft fibers without any admixture of 
artificial fibers, and shall be free from thread, leaf, and shell fiber 
dust. A suitable material for this purpose is sold in the form of rolls 
for surgical use. A pad shall be cut measuring 10 cm. x 10 cm. 
approximately 2 cm. thick and weighing between 3 and 4 grams. It shall 
be oven-dried prior to the test. The pad shall be attached by means of 
wire clips to a 10 cm. x 10 cm. frame of 1 mm. diameter. A wire handle 
approximately 75 cm. long attached to the frame would facilitate its use 
on the specimen.
    (3) When testing for cracks or openings during the test, the pad 
shall be held in a vertical position facing the crack or opening with 
the aperture located in a central part of the cotton wool. The pad may 
be reused if it has not absorbed any moisture or become charred during 
the previous application.
    (f) Temperature observations. (1) All observations shall be taken at 
intervals not exceeding 5 minutes. The surface temperatures on the 
unexposed side of the test specimen shall be measured by thermocouples 
located as follows:
    (i) One thermocouple located approximately in the center of each 
quadrant of the steel plate (four thermocouples total).
    (ii) One thermocouple close to the center of the test specimen, but 
away from the joint, if any.
    (iii) At least one thermocouple at the vertical joint of the test 
specimen.
    (iv) Further thermocouples at the discretion of the testing 
laboratory or Coast Guard for the purpose of determining the temperature 
at points deemed likely to give a greater temperature rise than any of 
the above mentioned thermocouples.
    (2) The average temperature rise on the unexposed surface shall be 
obtained by averaging the readings of the thermocouples mentioned in 
paragraphs (f)(1) (i) and (ii) of this section.
    (g) Other observations. Throughout the test, observations shall be 
made of all changes and occurrences, which are not criteria of 
performance but which may create hazard in case of a fire; for example 
the emission of appreciable volumes of smoke or noxious vapors from the 
unexposed side of the test specimen. The specimen shall be examined 
after the test for changes that have taken place and the information 
shall be noted in the test report.
    (h) Duration of testing. The test shall be continued for at least 30 
minutes to meet the requirements of Sec.  164.008-2(b) or at least 60 
minutes to meet the requirements of Sec.  164.008-2(c). In either case, 
the test shall be continued until the maximum surface temperature rise 
values noted in Sec.  164.008-4(a) have been reached, or until cracks 
which lead to flaming as specified in Sec.  164.008-4(b) are formed.

Sec.  164.008-4  Test requirements.

    (a) Thermal insulation: The insulation value of the specimens for 
the full scale test shall be such that the average temperature of 
thermocouples on the unexposed surface described in Sec.  164.008-
3(f)(2) will not rise more than 139 [deg]C. (250 [deg]F.) above the 
initial temperature, nor will the temperature at any point on the 
surface, including any joint, rise more than 225 [deg]C. (405 [deg]F.) 
above the initial temperature at the end of 15 minutes. When failure is 
due to excessive temperature rise on the joint, consideration will be 
given to alternate joint construction. The results obtained on the small 
scale test (2[foot] x 2[foot]) (60 cm. x 60 cm.) shall be recorded.
    (b) The test shall determine the length of time, up to one hour, 
that the bulkhead panel, including the joint can withstand the passage

2009]



Sec.  164.009-13  Furnace calibration.

    A calibration is performed on each new furnace and on each existing 
furnace as often as necessary to ensure

[[Page 405]]

that the furnace is in good working order. In each calibration the 
energy input to the furnace is adjusted so that the furnace thermocouple 
gives a steady reading of 750 10 [deg]C. The wall 
temperature of the furnace tube is then measured by an optical micro-
pyrometer at intervals of 10mm on 3 equally spaced vertical axes. The 
furnace is correctly calibrated if the temperature of the furnace tube 
wall is between 825 and 875 [deg]C. 50 mm above and below the midline of 
the wall and if the average wall temperature is approximately 850 
[deg]C.



Sec.  164.009-15  Test procedure.

    (a) General. Paragraphs (b) through (k) of this section contain the 
test procedures for each material submitted for approval, except 
fiberglass and other materials that melt at 750[deg] 10 [deg]C. Paragraph (l) of this section contains test 
procedures for fiberglass and other materials that melt at 750[deg] 
10 [deg]C.
    (b) Preparation of specimens. (1) The designated laboratory prepares 
5 cylindrical specimens representative of the properties of the sample 
submitted for testing. The dimensions of each specimen are as follows:

diameter: 45(+2/-0) mm
height: 50 3 mm
volume: 80 5 cm\3\

    (2) If the height of the sample, except a composite material, is 
less than 47 mm, the specimens prepared consist of layers of the sample.
    (3) If the sample is a composite material and has a height that is 
not 50 3mm, the layers of the specimen prepared 
are proportional in thickness to the layers of the sample.
    (4) The top and bottom faces of each specimen prepared are the faces 
of the material as manufactured.
    (5) If it is not practicable to prepare a specimen by the procedures 
described in paragraphs (b)(2) through (b)(4) of this section, the test 
is performed on five specimens of each component of the sample made to 
the dimensions prescribed in paragraph (b)(1) of this section.
    (c) Conditioning of specimen. Each specimen is conditioned for at 
least 20 hours in a ventilated oven maintained at 60 5 [deg]C. and is then cooled to room temperature in a 
desiccator.
    (d) Weight of specimen. The weight of each conditioned specimen 
after cooling is determined before it is tested.
    (e) Placement of specimen in holder. After a specimen is conditioned 
and weighed, it is placed in the specimen holder. A specimen that is 
made of layers of a composite material is held firmly together in the 
specimen holder.
    (f) Attachment of thermocouples. After the specimen is placed in the 
specimen holder, the thermocouples are attached to the specimen as 
follows: A vertical hole with a diameter of 2 mm and a depth that is 
half the height of the specimen is made in the center of the top of the 
specimen. The specimen thermocouple is then inserted into the hole so 
that its hot junction is at the center of the specimen. The surface 
thermocouple is put in contact with the surface of the specimen at its 
mid-height.
    (g) Preparation of the apparatus. The apparatus is examined to 
determine whether it is in good working order and to ensure that the 
equipment is protected against drafts and is not exposed to direct 
sunlight or artificial illumination. The furnace temperature is 
stabilized at 750 [deg]C. 10 [deg]C. and kept at 
that temperature for the duration of the test. The furnace temperature 
is stabilized when no adjustments are needed in the energy input to the 
furnace to keep the temperature constant.
    (h) Insertion of specimen. After the furnace temperature is 
stabilized for at least 10 minutes, the specimen is inserted into the 
furnace. The insertion is completed within 5 seconds. The specimen is 
positioned so that the hot junction of the surface thermocouple is 
diametrically opposite the hot junction of the furnace thermocouple.
    (i) Heating period. The heating period begins upon insertion of the 
specimen into the furnace and continues for 20 minutes, or until peak 
temperatures have passed.
    (j) Test observations. Temperature measurements at each thermocouple 
are made at intervals of not more than 10 seconds during the heating 
period, and note is taken of the occurrence and duration of any flaming. 
At the end of

[[Page 406]]

the heating period, the specimen is removed from the furnace and weighed 
while still hot.
    (k) Test results. Material is approved under this subpart if the 
test results of the sample submitted are within the following limits:
    (1) The highest temperature recorded for each specimen during the 
test by the furnace thermocouple, when averaged with the highest 
temperatures recorded for the other specimens, is not more than 50 
[deg]C. above the stabilized furnace temperature.
    (2) The highest temperature recorded for each specimen during the 
test by the surface thermocouple, when averaged with the highest 
temperatures recorded for the other specimens, is not more than 50 
[deg]C. above the stabilized furnace temperature.
    (3) The duration of flaming of each specimen during the test, when 
averaged with duration of flaming recorded for the other specimens, is 
not more than 10 seconds.
    (4) The average weight loss of the specimens after heating is not 
more than 50 percent of their average weight after conditioning.
    (l) Fiberglass and other materials that melt at 750 [deg]C. 10 [deg]C. If the material submitted for approval is 
fiberglass or other material that melts at 750[deg] 10 [deg]C., it is tested as described in paragraphs (b) 
through (k) of this section, except the average weight loss of the 
sample is determined as follows:
    (1) Five cylindrical specimens in addition to the five cylindrical 
specimens required in paragraph (b) of this section are prepared as 
described in paragraph (b) of this section.
    (2) Each of the additional specimens is placed on a weighing dish 
and both the specimen and the weighing dish are conditioned as described 
in paragraph (c) of this section.
    (3) The weight of each specimen and its weighing dish is determined 
as described in paragraph (d) of this section.
    (4) After a specimen and weighing dish are conditioned and weighed, 
they are placed in the specimen holder with the specimen supported by 
weighing dish. No specimen thermocouple or surface thermocouple is 
attached to the specimen.
    (5) The apparatus is prepared as described in paragraph (g) of this 
section, and after the furnace temperature has stabilized for at least 
10 minutes, the specimen and weighing dish are inserted into the 
furnace. The specimen and weighing dish are then heated for 20 minutes 
or until peak temperatures have passed. At the end of the heating 
period, the specimen and weighing dish are removed from the furnace and 
weighed while still hot.
    (6) The average weight loss of the specimens after heating may not 
be more than 50 percent of their average weight before heating.



Sec.  164.009-17  Density measurement.

    (a) The measurements described in this section are made to determine 
the density of a sample.
    (b) If the sample is a solid material, a specimen that has a length 
of 305 mm, a width of 305 mm, and thickness equal to that of the sample 
is prepared. The length and width are measured to the nearest 0.80 mm 
and the thickness to the nearest 0.25 mm. Allowance is made for any 
irregularity in the surfaces of the specimen. The average of at least 
four measurements of each dimension is determined.
    (c) If the sample is fibrous insulation, a specimen is prepared from 
sheets of the sample submitted. The sample is a cube and each dimension 
is 305 mm 1.60 mm. The average of at least four 
measurements of each dimension is determined.
    (d) The weight of a specimen is determined with a sensitive balance 
scale accurate to at least 0.5 percent of the weight of the specimen.
    (e) The dimension and weight measurements of a specimen are made

limited number of coats of any standard paint, or any ``Incombustible 
Material'' approved under subpart 164.009 of this subchapter in any 
thickness, or a combination thereof, are considered as automatically 
satisfying the intent of this specification and no test or proof of 
compliance will be required. Paint may be applied to one or both sides 
of ``Bulkhead Panels'' or ``Incombustible Materials,'' but it shall 
never be applied as an internal layer in sandwich or laminar 
construction.

    (b) Density. The density of the material shall be determined by 
dividing the weight of the material by its volume and shall be expressed 
in pounds per cubic foot. The volume shall be determined by measuring 
the volume of water displaced by the material or by direct measurement 
of the specimen using vernier calipers reading to 0.001 inch A sheet 
specimen 4 x 4 x thickness furnished shall be used 
unless the foam is molded shape, then the largest single piece so molded 
shall be used.
    (c) Buoyancy in fresh water--(1) Specimens. The buoyancy test shall 
be made with a sample of the sheet material measuring 12 x 
12 x thickness of material furnished or with the largest 
molded shape furnished.
    (2) Procedure. Securely attach a spring scale in a position directly 
over a test tank. Suspend a weighted wire basket from the scale in such 
a manner that the basket can be weighed while completely submerged in 
water. Proceed as follows:
    (i) Weigh the empty basket under water.
    (ii) Place the sample inside the basket and submerge it so that the 
top of the basket is at least 2 inches below the surface of the water. 
Allow the samples to remain submerged for 24 hours.
    (iii) After 24 hours submergence period, weigh the wire basket with 
the sample inside while both are still under water.
    (iv) The buoyancy is computed as paragraph (c)(2)(i) of this section 
minus (c)(2)(iii) of this section. The resulting value is divided by the 
volume of the polyvinyl chloride foam expressed in cubic feet. The final 
result is in lbs./cu. ft.
    (d) Volume loss on heat aging--(1) Specimen. Test specimens shall 
consist of pieces 4 x 4 x the thickness of the 
material furnished. Where the foam is an object of molded shape, the 
largest single piece so molded shall be used for this test.
    (2) Procedure. Volume before and after the heat aging test shall be 
determined by measuring the volume of water displaced by the material. 
The specimens shall be placed in an oven maintained at 140[deg] 2 [deg]F., for a period of one week. At the end of that 
period the specimens shall be removed from the oven and allowed to 
recover in the open for 5 hours at 70[deg] 2 
[deg]F. before the measurement of final volume is made. The test shall 
be run in triplicate, the results averaged and the percentage of volume 
loss calculated.
    (e) Compression deflection. Compression deflection shall be 
determined in accordance with method 12151 of Federal Standard 601, 
except that the deflection shall be maintained at 25 percent with 
automatic or manual control, and the load observed and recorded 60 
seconds after the 25 percent deflection is reached.
    (f) Compression set--(1) Specimens. The specimens shall have 
parallel top and bottom surfaces which shall be at right angles to the 
side surfaces. The specimen may be cylindrical or rectangular. The 
minimum dimension across the top shall be at least 1.0 times the 
thickness and the top a minimum of 1 square inch in area, and a maximum 
of 16 square inches in area.
    (2) Apparatus. The apparatus shall consist of a compression device 
with two parallel plates, between which the test specimen shall be 
compressed by means of four studs and nuts. The plates may be steel, 
aluminum or any rigid smooth metal of sufficient thickness to withstand 
the required compression stresses without bending. The surfaces against 
which the test specimens are held shall be smooth and shall be 
thoroughly cleaned and wiped dry before each test. Metal shims inserted 
between the plates shall be used to limit the compression of the 
specimen.
    (3) Procedure. Thickness, before and after the compression set test 
shall be measured as specified in paragraph (h)(1) of this section. The 
test specimens shall be compressed 25% of the original thickness for 22 
hours. At the end of that period, the test specimens shall be removed 
from the set apparatus and allowed to rest for 24 hours before 
measurement of final thickness is made. The compression set shall be 
calculated by means of the following formula:

Compression set (percent) = [(ho - hi) / 
(ho - hs)] x 100 (1)

where:


[[Page 414]]


ho = the original thickness.
hi = the thickness 24 hours after removal from apparatus.
hs = the test compression thickness.

    (g) Fire retardance--(1) Types A and C foams. The test specimens 
shall be \1/4\ inch in thickness, 1 inch in width and approximately 6 
inches in length. The specimens shall be clamped at one end in a 
position such that the long dimension forms a 45[deg] angle with the 
horizontal and with the widths in a vertical position. A Bunsen burner 
with a 1 inch yellow flame shall be applied to the lower or free end of 
the specimen for 15 seconds. The burner shall then be removed and the 
time that the specimen continues to burn after removal of the burner 
shall be recorded as burning time. The length of char shall also be 
recorded. The test shall be performed in a location free from drafts. 
The average results of three determinations shall be reported. A plain 
wax candle equivalent to those meeting Federal Specification C-C 91 may 
be substituted for the Bunsen burner.
    (2) Type B foam. The test specimens shall be \1/2\ inch in 
thickness, 2 inches in width and approximately 6 inches in length. The 
specimens shall be tested in accordance with American Society for 
Testing Materials Designation D-1692T specification standard.
    (h) Tensile strength and the ultimate elongation--(1) Specimens. The 
test specimens shall be dumbbell shaped, conforming in shape to die I of 
method 4111 of Standard FED-STD-601. The thickness of the specimen shall 
be \1/4\ inch. Two specimens shall be taken from the center of the 
sample piece and two from one side, keeping the skin surface intact. The 
thickness shall be measured to the nearest 0.001 inch by a suitable 
measurement device such as a vernier caliper with a sliding vernier to 
read 0.001 inch. Care shall be taken not to compress or distort the 
specimen when measuring. The specimens taken from the center will be 
skinless; the others will have skin on one side. One-inch bench marks 
shall be placed midway on the constricted portion of the tensile 
specimen.
    (2) Procedure. (i) The tensile strength of the specimens shall be 
determined in a standard tensile testing machine with a rate of 
separation of jaws set at 2 inches per minute. The bench marks shall be 
followed with a suitable pair of dividers until the specimen ruptures. A 
minimum of 4 specimens shall be tested and if any specimen breaks at the 
clamp or any specimen exhibits any obvious defects, the results obtained 
therewith shall be discarded. A new similar specimen shall then be 
prepared and tested. The tensile strength shall be calculated by 
dividing the breaking load (to the nearest 0.1 pound) by the original 
area of the cross section of the specimen in square inches and the 
result shall be expressed in pounds per square inch. The percent 
ultimate elongation shall be calculated as follows:

D1 - D / D x 100 (2)

where:

D = distance between knife edges of bench marker.
D1 = distance between bench marks at moment of rupture to the 
          nearest \1/32\ inch.

    (3) Averaging determinations. The tensile strength in pounds per 
square inch and percent ultimate elongation of four determinations shall 
be averaged for each sample.
    (i) Water absorption--(1) Specimens. Test specimens shall be 
4 x 4 square and approximately 1 in 
thickness. The specimen may have the natural skin on the top and bottom 
surfaces.
    (2) Procedure. The specimens shall be weighed and submerged in water 
under a 10-foot head of water (equal to 4.35 psi) at room temperature 
(65[deg]-95 [deg]F.) for 48 hours. The specimens shall then be placed in 
a stream of air for the minimum time required to remove visible water 
from the surface, and reweighed. The results shall be calculated in 
terms of pounds of water gain per square foot of total exposed surface.
    (j) Flexibility--(1) The size of the specimen shall be approximately 
1[foot] x 8[foot] with a thickness of \1/4\[foot] \1/16\. The test specimens and equipment 
shall be conditioned for at least 4 hours at 0 [deg]F. 2 [deg]F., and bent 180[deg] around a \1/2\ 
diameter steel mandrel within 5 seconds at the test temperature. Care 
shall be taken to avoid warming the test specimens, particularly at or 
near the bend point, in performing the test.

[[Page 415]]

    (k) Oil resistance--(1) Specimens. The test specimens shall be a 
disk approximately 1 in diameter and 1 
(approximately) in thickness.
    (2) Procedure. The specimen shall be immersed in fuel oil conforming 
to Navy special grade of Specification MIL-F-859 for 70 hours. The 
specimen shall then be removed, dipped in alcohol and blotted with 
filter paper. The specimen shall then be compared to an untreated 
specimen of similar size for apparent softness and visible swelling.
    (l) Odor. The odor of unicellular polyvinyl chloride foam shall be 
determined by sniffing.

Sec.  164.018-11  Approval tests.

    (a) Retroreflective material submitted for Coast Guard approval must 
be tested in accordance with the following test methods described in 
Federal Specification L-S-300:
    (1) Test conditions.
    (2) Test panels.
    (3) Adhesion test method using a 0.79 kg (1.75 lb.) test weight, 
except that one test panel must be immersed in distilled water in a 
covered container for 16 hours before the weight is applied and the 
other test panel must be immersed in salt water (4% NaCl by weight) in a 
covered container for 16 hours before the weight is applied. (This test 
method is required only for retroreflective material that is designed 
for use with an adhesive. If a particular test panel used in testing 
results in a test failure, the retroreflective material will not be 
approved for attachment to material of the type used as the test panel. 
The retroreflective material may nevertheless be approved for use with 
other types of material depending on the results of testing with the 
other panels. See paragraph (d) of this section for a listing of tests 
panels used.)
    (4) Flexibility at standard conditions test method, except that when 
testing Type I material--
    (i) The material must be unmounted;
    (ii) A 1.5 mm (\1/16\-inch) mandrel must be used in place of the 
mandrel described in the test method; and
    (iii) After testing at standard conditions, the material must be 
placed in a chamber at a temperature of -18 [deg]C. (0 [deg]F.) for at 
least 1 hour and then retested in the chamber at that temperature.
    (5) Reflective intensity.
    (6) Resistance to accelerated weathering test method and subtest 
methods ``reflective intensity after accelerated weathering,'' 
``reflective intensity during rainfall,'' and ``adhesion after 
accelerated weathering.'' (The ``adhesion after accelerated weathering'' 
test method is required only for materials designed for use with an 
adhesive. The ``resistance to accelerated weathering'' test method must 
be performed for 250 hours, if testing Type I material, and for 1,000 
hours if testing Type II material.)
    (7) Resistance to heat, cold, and humidity.
    (8) Fungus resistance.

[[Page 418]]

    (b) Retroreflective material submitted for approval must also be 
tested as follows:
    (1) Resistance to water immersion. Two test panels are used. The 
test panels and test conditions must meet paragraphs (a)(1) and (a)(2) 
of this section. The retroreflective material on each test panel is cut 
with a sharp knife from each corner to the corner diagonally opposite so 
that an ``X'' is formed. The cuts must be made completely through the 
material to the metal panel. One panel is immersed in distilled water in 
a covered container. The other panel is immersed in salt water (4% NaCl 
by weight) in a covered container. After 16 hours in water, the panels 
are removed from the containers, rinsed of deposits, and dried. 
Reflective intensity values at the angles listed in Table 164.018-9 must 
be measured within 2 hours after removal of the panels from the water. 
When measuring the reflective intensity values, the area within 5 mm 
(0.2 in.) of either side of the ``X'' cuts, and within 5 mm of the cut 
edges of the material, must not be counted.
    (2) Abrasion resistance. One test panel is used. The panel and test 
conditions must meet paragraphs (a)(1) and (a)(2) of this section. The 
test apparatus must meet Federal Test Method Standard 141, Method 6142, 
except that the brush must be dry. One thousand brush strokes are 
applied to the material. The test panel is then wiped with a clean soft 
cloth. Thereafter, the reflective intensity of the area of the material 
in contact with the brush is measured at the angles listed in Table 
164.018-9.
    (3) Soil resistance and cleanability. One panel is used. The test 
panel and test conditions must meet paragraphs (a)(1) and (a)(2) of this 
section. A soiling medium is applied to the material as described in 
Federal Test Method Standard 141, Method 6141. The soiled area is then 
covered with a laboratory watch glass or similar device. After 24 hours, 
the material is uncovered and the soil medium wiped off with a clean, 
dry, soft cloth. The material is then wetted with mineral spirits and 
wiped with a cloth soaked in mineral spirits. Thereafter, it is washed 
with a 1 percent (by weight) solution of detergent in warm water and 
rinsed and dried with a clean, dry, soft cloth.
    (c) Each measurement of reflective intensity required in paragraphs 
(a), (b)(1), and (b)(2) of this section must be made using either--
    (1) The L-S-300 procedure for measuring reflective intensity; or
    (2) The procedure for measuring specific intensity per unit area in 
Federal Test Method Standard 370, except that the test apparatus 
arrangement required in L-S-300 must be used.
    (d) If material is designed for use with an adhesive, the 
``adhesion'' test method required by paragraph (a)(3) of this section

manufacturer should then contract directly with an accepted independent 
laboratory to perform the required tests and inspections.
    (b) Upon completion of the required testing and inspections, the 
manufacturer must submit either a written request for type approval to 
the Commandant (CG-ENG-4), United States Coast Guard, 2703 Martin Luther 
King Jr. Avenue SE., Stop 7509, Washington, DC 20593-7509, or 
electronically submit a request to [email protected]. The request 
must indicate the name and address of the manufacturer, all product 
designations, and the address of all manufacturing facilities. The 
request must include a copy of the final fire test report and the 
production inspection procedures. From the information submitted, the 
Commandant determines whether or not the product is acceptable for type 
approval. If the product is determined to be acceptable, a type approval 
certificate valid for a 5-year period will be issued. If the product is 
not accepted, the manufacturer will be notified of the reasons why.

Sec.  164.141-3  Testing, marking, and inspection requirements.

    (a) All plastic piping submitted for approval must meet the flame 
spread requirements of IMO Resolution A.653(16) as modified for pipes by 
IMO Resolution A.753(18) and IMO Resolution MSC.313(88) (all 
incorporated by reference, see Sec.  164.141-2) except that:
    (1) The test specimens need not be wrapped in aluminum foil; and
    (2) Testing need not be conducted on every pipe size. Testing may be 
conducted on piping sizes with the maximum and minimum wall thickness 
intended to be approved. This will qualify all piping sizes within the 
tested range.
    (b) In order to receive approval for fire endurance, pipe must be 
tested as indicated in IMO Resolution A.753(18) and IMO Resolution 
MSC.313(88). When satisfying the requirements for L1 or L2 service, the 
pipe will be approved for use in lesser service grades. The approval of 
piping systems of sizes different than those tested will be allowed as 
provided for in Table 164.141(a) of this subpart.

    (c) To be approved for smoke and toxicity requirements, piping 
systems must meet the requirements of Annex 1, Part 2 of the FTP Code 
(incorporated by reference, see Sec.  164.141-2) with the following 
modifications:
    (1) Plastic piping meeting paragraph 2.2 of Annex 2 of the FTP Code 
as having very low flame spread when tested to Part 5 are deemed to meet 
the smoke and toxicity requirements without testing to Part 2.
    (2) Testing need only be conducted on piping sizes with the maximum 
and minimum wall thicknesses intended to be approved.
    (3) The test sample should be fabricated by cutting pipes lengthwise

[[Page 448]]

into individual sections and then assembling the sections into a test 
sample as representative as possible of a flat surface. All cuts should 
be made normal to the pipe wall.
    (4) The number of sections that must be assembled together to form a 
square test sample with sides measuring 3 inches, should be that which 
corresponds to the nearest integral number of sections which will result 
in a test sample with an equivalent linearized surface width between 3 
and 3 \1/2\ inches. The surface width is defined as the measured sum of 
the outer circumference of the assembled pipe sections normal to the 
lengthwise sections.
    (5) The test samples should be mounted on calcium silicate board and 
held in place by the edges of the test frame and, if necessary, by wire. 
There should be no gaps between individual sections and the samples 
should be constructed so that the edges of two adjacent sections 
coincide with the centerline of the test holder.
    (6) The space between the concave unexposed surface of the test 
sample and the surface of the calcium silicate backing should be left 
void.
    (7) The void space between the top of the exposed test surface and 
the bottom edge of the sample holder frame should be filled with a high 
temperature insulating wool where the pipe extends under the frame.
    (8) When the pipes are to include fireproofing or coatings, the 
composite structure consisting of the segmented pipe wall and 
fireproofing shall be tested and the thickness of the fireproofing 
should be the minimum thickness specified for the intended usage.
    (9) Test samples should be oriented in the apparatus such that the 
pilot burner flame will be normal to the lengthwise piping sections.
    (d) Where required to be approved, piping systems must comply with 
the non-metallic materials requirements in 46 CFR 56.60-25(a)(1).
    (e) All testing and inspections required by this subpart, except as 
allowed by paragraph (b) of this section, must be performed by an 
independent laboratory accepted by the Coast Guard under subpart 159.010 
of this chapter. A list of independent laboratories accepted as meeting 
subpart 159.010 of this chapter is available online at http://
psix.uscg.mil/EQLabs/Default.aspx.
    (f) The independent laboratory must perform an initial factory 
inspection to select the test specimens and establish the materials of 
construction, chemical make-up, dimensions, tolerances, and other 
related factors needed to confirm product consistency during follow-up 
production inspections.
    (g) Production inspections must be performed by the independent 
laboratory in accordance with subpart 159.007 of this chapter at least 
annually to confirm that no changes have been made to the product that 
may adversely affect its fire performance as plastic piping.
    (h) The independent laboratory must prepare production inspection 
procedures and a report of the results of the fire testing program, and 
must furnish the manufacturer with three copies of each upon completion 
of the required testing.
