Safety Standard for Bicycle Helmets; Proposed Rule
CONSUMER PRODUCT SAFETY COMMISSION
16 CFR Part 1203
Proposed Rule: Safety Standard for Bicycle Helmets
AGENCY: Consumer Product Safety Commission.
ACTION: Proposed rule.
SUMMARY: Pursuant to the Children's Bicycle Helmet Safety Act of 1994,
the Commission is proposing a safety standard that would require
bicycle helmets to meet impact-attenuation and other requirements. This
proposal modifies the bicycle helmet standard proposed by the
Commission in the Federal Register of August 15, 1994.
The proposed standard establishes requirements derived from one or
more of the voluntary standards applicable to bicycle helmets. In
addition, the proposed standard includes requirements specifically
applicable to children's helmets and requirements to prevent helmets
from coming off during an accident. The proposed standard also contains
testing and recordkeeping requirements to ensure that bicycle helmets
meet the standard's requirements.
DATES: Comments on the proposal should be submitted no later than
February 20, 1996.
Comments on elements of the proposal that, if issued, would
constitute collection of information requirements under the Paperwork
Reduction Act may be filed with the Office of Management and Budget
(``OMB''). OMB is required to make a decision concerning the
collections of information contained in the proposed rule between 30
and 60 days after publication. Thus, although comments will be received
by OMB until February 5, 1996, a comment to OMB is best assured of
having its full effect if OMB receives it by January 4, 1996.
ADDRESSES: Comments to the Commission should be mailed to the Office of
the Secretary, Consumer Product Safety Commission, Washington, D.C.
20207, or delivered to the Office of the Secretary, Consumer Product
Safety Commission, room 502, 4330 East-West Highway, Bethesda, Maryland
20814-4408, telephone (301)504-0800. Comments also may be filed with
the Commission by facsimile to (301)504-0127, or by electronic mail via
email@example.com. Comments should include a caption or cover indicating
that they are directed to the Office of the Secretary and are comments
on the revised proposed Safety Standard for Bicycle Helmets.
Comments to OMB should be directed to the Desk Officer for the
Consumer Product Safety Commission, Office of Information and
Regulatory Affairs, OMB, Washington, D.C. 20503. The Commission
encourages commenters to provide copies of such comments to the
Commission's Office of the Secretary, with a caption or cover letter
identifying the materials as comments submitted to OMB on the proposed
collection of information requirements for bicycle helmets.

Sec. 1203.17 Impact attenuation test.
(a) Test instruments and equipment. (1) Measurement of impact
attenuation. Impact attenuation is determined by measuring the
acceleration of the test headform during impact. Acceleration is
measured with a uniaxial accelerometer that is capable of withstanding
a shock of at least 1000 g. The helmet is secured onto the headform and
dropped in a guided free fall, using a monorail test apparatus (see
Figure 9), onto an anvil fixed to a rigid base. The base shall consist
of a solid mass of at least 135 kg (298 lb), the upper surface of which
shall consist of a steel plate at least 12 mm (0.47 in.) thick and
having a surface area of at least 0.10 m\2\ (1.08 ft\2\).
(2) Accelerometer. A uniaxial accelerometer is mounted at the
center of gravity of the test headform, with the sensitive axis aligned
within 5 degrees of vertical when the test headform is in the impact
position. The acceleration data channel and filtering shall comply with
SAE Recommended Practice J211 OCT88, Instrumentation for Impact Tests,
Requirements for Channel Class 1000.
(3) Headform and drop assembly--centers of gravity. The center of
gravity of the test headform is located at the center of the mounting
ball on the support assembly and lies within an inverted cone with its
axis vertical, and forming a 10 degree included angle with the vertex
at the point of impact. The location of the center of gravity of the
drop assembly (combined test headform and support assembly) must meet
FMVSS 218 S7.1.8. The center of gravity of the drop assembly lies
within the rectangular volume bounded by x = -6.4 mm (-0.25 in.), x =
21.6 mm (0.85 in), y = 6.4 mm (0.25 in.), and y = -6.4 mm (-0.25 in),
with the origin located at the center of gravity of the test headform.
The rectangular volume has no boundary along the z-axis. The x-y-z axes
are mutually perpendicular and have positive or negative designations
in accordance with the right-hand rule. The origin of the coordinate
axes is located at the center of the mounting ball on the support
assembly. The x-y-z axes of the test headform assembly on monorail
impact-test equipment are oriented as follows: From the origin, the x-
axis is horizontal with its positive direction going toward and passing
through the vertical centerline of the monorail. The positive z-axis is
downward. The y-axis also is horizontal, and its direction is decided
by the z- and x-axes, using the right-hand rule. See Figure 10 for an
overhead view of the x-y boundary of the location of the center of
(4) Drop assembly. The center of gravity of the headform shall be
at the center of the mounting ball.

A or ISO E) and support assembly (excluding the test helmet) for the
impact test shall be 3.9 0.1 kg (8.60 0.22 lb).
(5) Impact anvils. Impact tests shall be performed against the
three different anvils described below. All of the anvils shall be
constructed of steel and shall be solid (i.e., without internal
(i) Flat Anvil. The flat anvil shall have a flat surface area with
an impact face having a minimum diameter of 125 mm (4.92 in.) and shall
be at least 24 mm (0.94 in.) thick (see Figure 11).
(ii) Hemispherical anvil. The hemispherical anvil shall have an
impact surface with a radius of 48 1 mm (1.89
0.04 in.). The profile of the impact surface shall be one
half the surface of a sphere (see Figure 12).
(iii) Curbstone anvil. The curbstone anvil shall have two flat
faces making an angle of 105 degrees and meeting along a striking edge
with a radius of 15 mm 0.5 mm (0.59 0.02 in.).
The height of the curbstone anvil shall not be less than 50 mm (1.97
in.), and the length shall not be less than 200 mm (7.87 in.) (see
(b) Test Procedure. (1) Instrument system check. The impact-
attenuation test instrumentation shall be checked before and after each
series of tests (at least at the beginning and end of each test day) by
dropping an impactor with a spherical impact surface onto an
elastomeric test medium (MEP). The impactor shall be dropped onto the
MEP at a specified impact velocity (2% of a central value)
that is representative of helmet testing drop heights. Before
conducting a series of drops, the center vertical axis of the
accelerometer (see Sec. 1203.17(a)(2)) shall be aligned with the
geometric center of the MEP pad. Six impacts, at intervals of 75
15 seconds, shall be performed at the beginning and end of
the day. The first three impacts at the beginning and end of the day
shall be considered warm-up drops and shall be discarded from the
series. The test parameters selected at each laboratory shall produce
impact accelerations shown to be repeatable within 2% of a
(2) Impact sites. Each of helmets 1 through 4 (one helmet for each
conditioning environment) shall impact at four different sites, one
impact on the flat anvil, one impact on the hemispherical anvil, one
impact on the curbstone anvil, and one impact on an anvil chosen at the
discretion of the test personnel. The center of any impact may be
on or anywhere above the test line, provided it is at least 120 mm
(4.72 in), measured on the surface of the helmet, from any prior impact
center. Rivets and other mechanical fasteners, vents, and any other
helmet feature within the test region are valid test sites.
\4\The intent of this requirement is that the fourth impact will
be on the anvil likely to result in the highest g-value. In the
absence of an indication why another anvil would be more stringent,
this fourth impact should be made with the anvil that produced the
highest g-value in the previous three impacts.
(3) Impact velocity. The helmet shall be dropped onto the flat
anvil from a theoretical drop height of 2 meters (6.56 ft) to achieve
an impact velocity of 6.2 m/s 3% (20.34 ft/s
3%). The helmet shall be dropped onto the hemispherical and
curbstone anvils from a theoretical drop height of 1.2 meters (3.94 ft)
to achieve an impact velocity of 4.8 m/s 3% (15.75 ft/s
3%). The impact velocity shall be measured during the last
40 mm (1.57 in) of free-fall for each test.
(4) Helmet position. Prior to each test, the helmet shall be
positioned on the test headform in accordance with the HPI. The helmet
shall be secured so that it does not shift position prior to impact.
The helmet retention system shall be secured in a manner that does not
interfere with free-fall or impact.
(5) Data. Record the maximum acceleration in g's during impact.
Sec. 1203.18 Reflectivity. [Reserved]
Sec. 1203.30 Purpose and scope.
(a) Purpose. Section 14(a) of the Consumer Product Safety Act
(CPSA), 15 U.S.C. 2063(a), requires every manufacturer (including
importers) and private labeler of a product which is subject to a
consumer product safety standard to issue a certificate that the
product conforms to the applicable standard. Section 14(a) further
requires that the certificate be based either on a test of each product
or on a ``reasonable testing program.'' The purpose of this subpart is
to establish requirements that manufacturers and importers of bicycle
helmets subject to the Safety Standard for Bicycle Helmets (Subpart A
of this Part 1203) shall issue certificates of compliance in the form
(b) Scope. The provisions of this subpart apply to all bicycle
helmets that are subject to the requirements of the Safety Standard for
Sec. 1203.31 Effective date.
Any bicycle helmet manufactured more than 1 year after publication
of a final rule must meet the standard and must be certified as
complying with the standard in accordance with this Subpart B.
Sec. 1203.32 Definitions.
The following definitions shall apply to this subpart:
(a) Foreign manufacturer means an entity that manufactured a
bicycle helmet outside the United States.
(b) Manufacturer means the entity that either manufactured a helmet
in the United States or imported a helmet manufactured outside the
(c) Private labeler means an owner of a brand or trademark that is
used on a bicycle helmet subject to the standard and which is not the
brand or trademark of the manufacturer of the bicycle helmet, provided
the owner of the brand or trademark caused, authorized, or approved its
(d) Production lot means a quantity of bicycle helmets from which
certain bicycle helmets are selected for testing prior to certifying
the lot. All bicycle helmets in a lot must be essentially identical in
those design, construction, and material features that relate to the
ability of a bicycle helmet to comply with the standard.
(e) Reasonable testing program means any tests which are identical
or equivalent to, or more stringent than, the tests defined in the
standard and which are performed on one or more bicycle helmets
selected from the production lot to determine whether there is
reasonable assurance that all of the bicycle helmets in that lot comply
with the requirements of the standard.
Sec. 1203.33 Certification testing.
(a) General. Manufacturers, as defined in Sec. 1203.32(a), shall
conduct a reasonable testing program to demonstrate that their bicycle
helmets comply with the requirements of the standard.
(b) Reasonable testing program. This paragraph provides guidance
for establishing a reasonable testing program.
(1) Manufacturers and importers may define their own reasonable
testing programs. Reasonable testing programs may, at the option of
manufacturers and importers, be conducted by an independent third party
qualified to perform such testing programs. However, manufacturers, as
defined in Sec. 1203.32(a), are responsible for insuring compliance
with all requirements of this standard.
(2) To conduct a reasonable testing program, the bicycle helmets
shall be divided into production lots. Sample bicycle helmets from each
production lot shall be tested in accordance with the reasonable
testing program. Whenever there is a change in parts, suppliers of
parts, or production methods that could affect the ability of the
bicycle helmet to comply with the requirements of the standard, the
manufacturer shall establish a new production lot for testing.
(3) The Commission will test for compliance with the standard by
using the standard's test procedures. However, a reasonable testing
program need not be identical to the tests prescribed in the standard.
(4) If the reasonable testing program shows that a bicycle helmet
may not comply with one or more requirements of the standard, no
bicycle helmet in the production lot can be certified as complying
until all noncomplying bicycle helmets in the lot have been identified
and destroyed or altered by repair, redesign, or use of a different
material or components to the extent necessary to make them conform to
(5) The sale or offering for sale of a bicycle helmet that does not
comply with the standard is a prohibited act and a violation of
Sec. 19(a) of the CPSA (15 U.S.C. 2068(a)), regardless of whether the
bicycle helmet has been validly certified.
Sec. 1203.34 Product certification and labeling by manufacturers
(a) Form of permanent label of certification. Manufacturers, as
defined in Sec. 1203.32(a), shall issue certificates of compliance for
bicycle helmets manufactured after the effective date of the standard
in the form of a legible and readily visible label which can reasonably
be expected to remain on the bicycle helmet and legible for the
intended design life of the helmet. Such labeling shall be deemed to be
a certificate of compliance, as that term is used in Sec. 14 of the
CPSA, 15 U.S.C. 2063.
(b) Contents of certification label. The certification labels
required by this section shall contain the following:
(1) The statement ``Complies with CPSC Safety Standard for Bicycle
Helmets for Adults and Children Age 5 and Older (16 CFR 1203)'' or
``Complies with CPSC Safety Standard for Bicycle Helmets for Children
Under 5 Years (16 CFR 1203)'', as appropriate (for a helmet that meets
the criteria for both an adult helmet and a helmet for children under
age 5, the label may state ``Complies with the CPSC Safety Standard for
Bicycle Helmets for Persons of All Ages'', or equivalent language);
(2) The name of the U.S. manufacturer or importer responsible for
issuing the certificate;
(3) The address of the U.S. manufacturer or importer responsible
for issuing the certificate or, if the name of a private labeler is on
the label, the address of the private labeler;
(4) The name and address of the foreign manufacturer, if the helmet
was manufactured outside the United States;
(5) An identification of the production lot; and
(6) The month and year the product was manufactured.
(c) Coding. (1) The information required by paragraphs (b) (4)
through (6) of this section may be in code, provided:
(i) the person or firm issuing the certificate maintains a written
record of the meaning of each symbol used in the code, and
(ii) the record shall be made available to the distributor,
retailer, consumer, and Commission upon request.
(2) A serial number may be used in place of a production lot
identification on the helmet if it can serve as a code to identify the
production lot. If a bicycle helmet is manufactured for sale by a
private labeler, and if the name of the private labeler is on the
certification label, the name of the manufacturer or importer issuing
the certificate, and the name and address of any foreign
manufacturer, may also be in such a code.
(d) Placement of the label(s). The information required by
paragraphs (b) (2) through (3) must be on one label, unless allowed to
be in code. The other required information may be on separate labels.
The label(s) required by this section must be affixed to the bicycle
helmet. If the label(s) are not immediately visible to the ultimate
purchaser of the bicycle helmet prior to purchase because of packaging
or other marketing practices, a second label is required. That label
shall state, as appropriate, ``Complies with CPSC Safety Standard for
Bicycle Helmets for Adults and Children Age 5 and Older'', or
``Complies with CPSC Safety Standard for Bicycle Helmets for Children
Under 5 Years''. The additional label must appear on the container or,
if the container is not visible before purchase, on the promotional
material used with the sale of the bicycle helmet. (For a helmet that
meets the criteria for both an adult helmet and a helmet for children
under age 5, the label may state ``Complies with the CPSC Safety
Standard for Bicycle Helmets for Persons of All Ages'', or equivalent
(e) Additional provisions for importers.
(1) General. The importer of any bicycle helmet subject to the
standard in Subpart A of this Part 1203 must issue the certificate of
compliance required by Sec. 14(a) of the CPSA and this section.
(i) If a reasonable testing program meeting the requirements of
this subpart has been performed by or for the foreign manufacturer of
the product, the importer may rely in good faith on such tests to
support the certificate of compliance provided:
(A) the importer is a resident of the United States or has a
resident agent in the United States,
(B) the records of such tests required by Sec. 1203.41 of Subpart C
of this part are maintained in the United States, and
(C) such records are available to the Commission upon request to
(ii) Test records may be maintained outside of the United States if
they will be provided to the Commission within 48 hours of a request
for the records.
(2) Responsibility of importer. If the importer relies on tests by
the foreign manufacturer to support the certificate of compliance, the
importer shall--in addition to complying with paragraph (e(1)of this
section--examine the records supplied by the manufacturer to determine
that they comply with Sec. 1203.41 of Subpart C of this part.
Sec. 1203.40 Effective date.
The recordkeeping requirements in this subpart are effective [1
year after publication of the final rule] and apply to bicycle helmets
manufactured after that date.
Sec. 1203.41 Recordkeeping requirements.
