High profile helmet case against Citi bike

This is an interesting recent case against the very large and prominent Citi Bike operation in New York. There has been a lot of media attention on them.  Unfortunately it is not clear from the article what stage the case is in. Our research shows that it was filed February 27, 2014. I suspect that some discovery will need to take place before dismissal motions can be made on legal grounds. There is no discussion in the article as to what legal issues are at play. We will try to keep you posted on this case as it progresses. Additional dates we now know about are as follows: No party may make a motion for summary judgment until May 11, 2015 (this weill be a key date). Discovery is due to be completed by 2/9/2015. Expert witness discovery due by 4/9/2015.

Helmet Use Among U.S. Motorcyclists Who Died in Crashes 2008–2010



This is an interesting and quite detailed study regarding the use of motorcycle helmets. It would be interesting to see how much of this data is transmutable to bicycle helmet use or non use and related injuries. The CDC (Centers for Disease Control; cdc.gov) analysed fatal crash data from 2008 to 2010, where a total of 14,283 motorcyclists were killed in crashes, among whom 6,057 (42 percent) were not wearing a helmet. In the 20 states with a universal helmet law (like California), 739 (12 percent) fatally injured motorcyclists were not wearing a helmet, compared with 4,814 motorcyclists (64 percent) in the 27 states with partial helmet laws and 504 (79 percent) motorcyclists in the three states without a helmet law. As of April 2012, 19 states and the District of Columbia had universal helmet laws, 28 states had partial helmet laws, and three states had no helmet law. The full report is available here in pdf

S6. Preliminary test procedures. Before subjecting a helmet to the

testing sequence specified in S7., prepare it according to the

procedures in S6.1, S6.2, and S6.3.

S6.1 Selection of appropriate headform.

S6.1.1 A helmet with a manufacturer's designated discrete size or

size range which does not exceed 6\3/4\ (European size: 54) is tested on

the small headform. A helmet with a manufacturer's designated discrete

size or size range which exceeds 6\3/4\, but does not exceed 7\1/2\

(European size: 60) is tested on the medium headform. A helmet with a

manufacturer's designated discrete size or size range which exceeds 7\1/

2\ is tested on the large headform.

S6.1.2 A helmet with a manufacturer's designated size range which

includes sizes falling into two or all three size ranges described in

S6.1.1 is tested on each headform specified for each size range.

S6.2 Reference marking.

S6.2.1 Use a reference headform that is firmly seated with the basic

and reference planes horizontal. Place the complete helmet to be tested

on the appropriate reference headform, as specified in S6.1.1 and

S6.1.2.

S6.2.2 Apply a 10-pound (4.5 kg) static verticle load through the

helmet's apex. Center the helmet laterally and seat it firmly on the

reference headform according to its helmet positioning index.

S6.2.3 Maintaining the load and position described in S6.2.2, draw a

line (hereinafter referred to as ``test line'') on the outer surface of

the helmet coinciding with portions of the intersection of that service

with the following planes, as shown in Figure 2:

(a) A plane 1 inch (2.5 cm) above and parallel to the reference

plane in the anterior portion of the reference headform;

(b) A vertical transverse plane 2.5 inches (6.4 cm) behind the point

on the anterior surface of the reference headform at the intersection of

the mid-sagittal and reference planes;

(c) The reference plane of the reference headform;

(d) A vertical transverse plane 2.5 inches (6.4. cm) behind the

center of the external ear opening in a side view; and

(e) A plane 1 inch (2.5 cm) below and parallel to the reference

plane in the posterior portion of the reference headform.

S6.3 Helmet positioning.

S6.3.1 Before each test, fix the helmet on a test headform in the

position that conforms to its helmet positioning index. Secure the

helmet so that it does not shift position before impact or before

application of force during testing.

S6.3.2 In testing as specified in S7.1 and S7.2, place the retention

system in a position such that it does not interfere with free fall,

impact or penetration.

S6.4 Conditioning.

S6.4.1 Immediately before conducting the testing sequence specified

in S7, condition each test helmet in accordance with any one of the

following procedures:

(a) Ambient conditions. Expose to a temperature of

70 deg.F(21 deg.C) and a relative humidity of 50 percent for 12 hours.

(b) Low temperature. Expose to a temperature of 14 deg.F(-10 deg.C)

for 12 hours.

(c) High temperature. Expose to a temperature of 122 deg.F(50 deg.C)

for 12 hours.

(d) Water immersion. Immerse in water at a temperature of

77 deg.F(25 deg.C) for 12 hours.

S6.4.2 If during testing, as specified in S7.1.3 and S7.2.3, a

helmet is returned to the conditioning environment before the time out

of that environment exceeds 4 minutes, the helmet is kept in the

environment for a minimum of 3 minutes before resumption of testing with

that helmet. If the time out of the environment exceeds 4 minutes, the

helmet is returned to the environment for a minimum of 3 minutes for

each minute or portion of a minute that the helmet remained out of the

environment in excess of 4 minutes or for a maximum of 12 hours,

whichever is less, before the resumption of testing with that helmet.

S7. Test conditions.

S7.1 Impact attenuation test.

S7.1.1 Impact attenuation is measured by determining acceleration

imparted to an instrumented test headform on which a complete helmet is

mounted as specified in S6.3, when it is dropped in guided free fall

upon a fixed hemispherical anvil and a fixed flat steel anvil.

S7.1.2 Each helmet is impacted at four sites with two successive

identical impacts at each site. Two of these sites are impacted upon a

flat steel anvil and two upon a hemispherical steel anvil as specified

in S7.1.10 and S7.1.11. The impact sites are at any point on the area

above the test line described in paragraph S6.2.3, and separated by a

distance not less than one-sixth of the maximum circumference of the

helmet in the test area.

S7.1.3 Impact testing at each of the four sites, as specified in

S7.1.2, shall start at two minutes, and be completed by four minutes,

after removal of the helmet from the conditioning environment.

S7.1.4 (a) The guided free fall drop height for the helmet and test

headform combination onto the hemispherical anvil shall be such that the

minimum impact speed is 17.1 feet/second (5.2 m/sec). The minimum drop

height is 54.5 inches (138.4 cm). The drop height is adjusted upward

from the minimum to the extent necessary to compensate for friction

losses.

(b) The guided free fall drop height for the helmet and test

headform combination onto the flat anvil shall be such that the minimum

impact speed is 19.7 ft./sec (6.0 m/sec). The minimum drop height is 72

inches (182.9 cm). The drop height is adjusted upward from the minimum

to the extent necessary to compensate for friction losses.

S7.1.5 Test headforms for impact attenuation testing are constructed

of magnesium alloy (K-1A), and exhibit no resonant frequencies below

2,000 Hz.

S7.1.6 The monorail drop test system is used for impact attenuation

testing.

S7.1.7 The weight of the drop assembly, as specified in Table 1, is

the combined weight of the test headform and the supporting assembly for

the drop test. The weight of the supporting assembly is not less than

2.0 lbs. and not more than 2.4 lbs. (0.9 to 1.1 kg). The supporting

assembly weight for the monorail system is the drop assembly weight

minus the combined weight of the test headform, the headform's

clamp down ring, and its tie down screws.

S7.1.8 The center of gravity of the test headform is located at the

center of the mounting ball on the supporting assembly and lies within a

cone with its axis vertical and forming a 10 deg. included angle with

the vertex at the point of impact. The center of gravity of the drop

assembly lies within the rectangular volume bounded by x = -0.25 inch

(-0.64 cm), x = 0.85 inch (2.16 cm), y = 0.25 inch (0.64 cm), and y =

-0.25 inch (-0.64 cm) 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 (See Figure

5). The origin of the coordinate axes also is located at the center of

the mounting ball on the supporting assembly (See Figures 6, 7, and 8).

The x-y-z axes of the test headform assembly on a monorail drop 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 can be decided

by the z- and x-axes, using the right-hand rule.

S7.1.9 The acceleration transducer is mounted at the center of

gravity of the test headform with the sensitive axis aligned to within

5 deg. of vertical when the test headform assembly is in the impact

position. The acceleration data channel complies with SAE Recommended

Practice J211 JUN 80, Instrumentation for Impact Tests, requirements for

channel class 1,000.

S7.1.10 The flat anvil is constructed of steel with a 5-inch (12.7

cm) minimum diameter impact face, and the hemispherical anvil is

constructed of steel with a 1.9 inch (4.8 cm) radius impact face.

S7.1.11 The rigid mount for both of the anvils consists of a solid

mass of at least 300 pounds (136.1 kg), the outer surface of which

consists of a steel plate with minimum thickness of 1 inch (2.5 cm) and

minimum surface area of 1 ft \2\ (929 cm \2\ ).

S7.1.12 The drop system restricts side movement during the impact

attenuation test so that the sum of the areas bounded by the

acceleration-time response curves for both the x- and y-axes (horizontal

axes) is less than five percent of the area bounded by the acceleration-

time response curve for the vertical axis.

S7.2 Penetration test.

S7.2.1 The penetration test is conducted by dropping the penetration

test striker in guided free fall, with its axis aligned vertically, onto

the outer surface of the complete helmet, when mounted as specified in

S6.3, at any point above the test line, described in S6.2.3, except on a

fastener or other rigid projection.

S7.2.2 Two penetration blows are applied at least 3 inches (7.6 cm)

apart, and at least 3 inches (7.6 cm) from the centers of any impacts

applied during the impact attenuation test.

S7.2.3 The application of the two penetration blows, specified in

S7.2.2, starts at two minutes and is completed by four minutes, after

removal of the helmet from the conditioning environment.

S7.2.4 The height of the guided free fall is 118.1 inches (3 m), as

measured from the striker point to the impact point on the outer surface

of the test helmet.

S7.2.5 The contactable surface of the penetration test headform is

constructed of a metal or metallic alloy having a Brinell hardness

number no greater than 55, which will permit ready detection should

contact by the striker occur. The surface is refinished if necessary

before each penetration test blow to permit detection of contact by the

striker.

S7.2.6 The weight of the penetration striker is 6 pounds, 10 ounces

(3 kg).

S7.2.7 The point of the striker has an included angle of 60 deg., a

cone height of 1.5 inches (3.8 cm), a tip radius of 0.02 inch (standard

0.5 millimeter radius) and a minimum hardness of 60 Rockwell, C-scale.

S7.2.8 The rigid mount for the penetration test headform is as

described in S7.1.11.

S7.3 Retention system test.

S7.3.1 The retention system test is conducted by applying a static

tensile load to the retention assembly of a complete helmet, which is mounted,

as described in S6.3, on a stationary test headform as shown in Figure

4, and by measuring the movement of the adjustable portion of the

retention system test device under tension.

S7.3.2 The retention system test device consists of both an

adjustable loading mechanism by which a static tensile load is applied

to the helmet retention assembly and a means for holding the test

headform and helmet stationary. The retention assembly is fastened

around two freely moving rollers, both of which have a 0.5 inch (1.3 cm)

diameter and a 3-inch (7.6 cm) center-to-center separation, and which

are mounted on the adjustable portion of the tensile loading device

(Figure 4). The helmet is fixed on the test headform as necessary to

ensure that it does not move during the application of the test loads to

the retention assembly.

S7.3.3 A 50-pound (22.7 kg) preliminary test load is applied to the

retention assembly, normal to the basic plane of the test headform and

symmetrical with respect to the center of the retention assembly for 30

seconds, and the maximum distance from the extremity of the adjustable

portion of the retention system test device to the apex of the helmet is

measured.

S7.3.4 An additional 250-pound (113.4 kg) test load is applied to

the retention assembly, in the same manner and at the same location as

described in S7.3.3, for 120 seconds, and the maximum distance from the

extremity of the adjustable portion of the retention system test device

to the apex of the helmet is measured.

Subpart A--The Standard

Sec. 1203.1 Scope, general requirements, and effective date.

(a) Scope. The standard in this subpart describes test methods and
defines minimum performance criteria for all bicycle helmets, as
defined in Sec. 1203.4(b).
(b) General requirements.
(1) Projections. All projections on bicycle helmets must meet the
construction requirements of Sec. 1203.5.
(2) Labeling and instructions. All bicycle helmets must have the
labeling and instructions required by Sec. 1203.6.
(3) Performance tests. All bicycle helmets must be capable of
meeting the peripheral vision, positional stability, dynamic strength
of retention system, and impact-attenuation tests described in
Secs. 1203.7 through 1203.17.
(4) Units. The values stated in International System of Units
(``SI'') measurements are the standard. The inch-pound values stated in
parentheses are for information only.
(c) Effective date. The standard shall become effective March 10,
1999 and shall apply to all bicycle helmets manufactured after that
date. Bicycle helmets manufactured from March 17, 1995 through March
10, 1999, inclusive, are subject to the requirements of Subpart D,
rather than this subpart A.

Sec. 1203.2 Purpose and basis.

The purpose and basis of this standard is to reduce the likelihood
of serious injury and death to bicyclists resulting from impacts to the
head, pursuant to 15 U.S.C. 6001-6006.

Sec. 1203.3 Referenced documents.

(a) The following documents are incorporated by reference in this
standard.
(1) Draft ISO/DIS Standard 6220-1983--Headforms for Use in the
Testing of Protective Helmets.\1\
---------------------------------------------------------------------------

\1\ Although the draft ISO/DIS 6220-1983 standard was never
adopted as an international standard, it has become a consensus
national standard because all recent major voluntary standards used
in the United States for testing bicycle helmets establish their
headform dimensions by referring to the draft ISO standard.
---------------------------------------------------------------------------

(2) SAE Recommended Practice SAE J211 OCT88, Instrumentation for
Impact Tests.
(b) This incorporation by reference was approved by the Director of
the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part
51. Copies of the standards may be obtained as follows. Copies of the
draft ISO/DIS Standard 6220-1983 are available from American National
Standards Institute, 11 W. 42nd St., 13th Floor, New York, NY 10036.
Copies of the SAE Recommended Practice SAE J211 OCT88, Instrumentation
for Impact Tests, are available from Society of Automotive Engineers,
400 Commonwealth Dr., Warrendale, PA 15096. Copies may be inspected at
the Office of the Secretary, Consumer Product Safety Commission, 4330
East-West Highway, Bethesda, Maryland 20814, or at the Office of the
Federal Register, 800 N. Capitol Street NW, Room 700, Washington, DC.

Sec. 1203.4 Definitions

(a) Basic plane means an anatomical plane that includes the
auditory meatuses (the external ear openings) and the inferior orbital
rims (the bottom edges of the eye sockets). The ISO headforms are
marked with a plane corresponding to this basic plane (see Figures 1
and 2 of this part).
(b) Bicycle helmet means any headgear that either is marketed as,
or implied through marketing or promotion to be, a device intended to
provide protection from head injuries while riding a
bicycle.2
---------------------------------------------------------------------------

\1\ Helmets specifically marketed for exclusive use in a
designated activity, such as skateboarding, rollerblading, baseball,
roller hockey, etc., would be excluded from this definition because
the specific focus of their marketing makes it unlikely that such
helmets would be purchased for other than their stated use. However,
a multi-purpose helmet--one marketed or represented as providing
protection either during general use or in a variety of specific
activities other than bicycling--would fall within the definition of
bicycle helmet if a reasonable consumer could conclude, based on the
helmet's marketing or representations, that bicycling is among the
activities in which the helmet is intended to be used. In making
this determination, the Commission will consider the types of
specific activities, if any, for which the helmet is marketed, the
similarity of the appearance, design, and construction of the helmet
to other helmets marketed or recognized as bicycle helmets, and the
presence, prominence, and clarity of any warnings, on the helmet or
its packaging or promotional materials, against the use of the
helmet as a bicycle helmet. A multi-purpose helmet marketed without
specific reference to the activities in which the helmet is to be
used will be presumed to be a bicycle helmet. The presence of
warnings or disclaimers advising against the use of a multi-purpose
helmet during bicycling is a relevant, but not necessarily
controlling, factor in the determination of whether a multi-purpose
helmet is a bicycle helmet.

Sec. 1203.10 Selecting the test headform.

A helmet shall be tested on the smallest of the headforms
appropriate for the helmet sample. A headform size is appropriate for a
helmet if all of the helmet's sizing pads are partially compressed when
the helmet is equipped with its thickest sizing pads and positioned
correctly on the reference headform.

Sec. 1203.11 Marking the impact test line.

Prior to testing, the impact test line shall be determined for each
helmet in the following manner.
(a) Position the helmet on the appropriate headform as specified by
the manufacturer's helmet positioning index (HPI), with the brow
parallel to the basic plane. Place a 5-kg (11-lb) preload ballast on
top of the helmet to set the comfort or fit padding.
(b) Draw the impact test line on the outer surface of the helmet
coinciding with the intersection of the surface of the helmet with the
impact line planes defined from the reference headform as shown in:
(1) Figure 4 of this part for helmets intended only for persons 5
years of age and older.
(2) Figure 5 of this part for helmets intended for persons age 1
and older.

test headform when tested in accordance with Sec. 1203.15 of this
standard.
(c) Dynamic strength of retention system. All bicycle helmets shall
have a retention system that will remain intact without elongating more
than 30 mm (1.2 in.) when tested in accordance with Sec. 1203.16 of
this standard.

[[Page 11732]]

(d) Impact attenuation criteria.
(1) General. A helmet fails the impact attenuation performance test
of this standard if a failure under paragraph (d)(2) of this section
can be induced under any combination of impact site, anvil type, anvil
impact order, or conditioning environment permissible under the
standard, either with or without any attachments, or combinations of
attachments, that are provided with the helmet. Thus, the Commission
will test for a ``worst case'' combination of test parameters. What
constitutes a worst case may vary, depending on the particular helmet
involved.
(2) Peak acceleration. The peak acceleration of any impact shall
not exceed 300 g when the helmet is tested in accordance with
Sec. 1203.17 of this standard.

Sec. 1203.13 Test schedule.

(a) Helmet sample 1 of the set of eight helmets, as designated in
Table 1203.13, shall be tested for peripheral vision in accordance with
Sec. 1203.14 of this standard.
(b) Helmet samples 1 through 8, as designated in Table 1203.13,
shall be conditioned in the ambient, high temperature, low temperature,
and water immersion environments as follows: helmets 1 and 5--ambient;
helmets 2 and 7--high temperature; helmets 3 and 6--low temperature;
and helmets 4 and 8--water immersion.
(c) Testing must begin within 2 minutes after the helmet is removed
from the conditioning environment. The helmet shall be returned to the
conditioning environment within 3 minutes after it was removed, and
shall remain in the conditioning environment for a minimum of 2 minutes
before testing is resumed. If the helmet is out of the conditioning
environment beyond 3 minutes, testing shall not resume until the helmet
has been reconditioned for a period equal to at least 5 minutes for
each minute the helmet was out of the conditioning environment beyond
the first 3 minutes, or for 4 hours, (whichever reconditioning time is
shorter) before testing is resumed.
(d) Prior to being tested for impact attenuation, helmets 1-4
(conditioned in ambient, high temperature, low temperature, and water
immersion environments, respectively) shall be tested in accordance
with the dynamic retention system strength test at Sec. 1203.16.
Helmets 1-4 shall then be tested in accordance with the impact
attenuation tests on the flat and hemispherical anvils in accordance
with the procedure at Sec. 1203.17. Helmet 5 (ambient-conditioned)
shall be tested in accordance with the positional stability tests at
Sec. 1203.15 prior to impact testing. Helmets 5-8 shall then be tested
in accordance with the impact attenuation tests on the curbstone anvil

anvil and release it, so that it impacts the stop anvil.
(5) The test shall be repeated with the headform's face pointing
upwards, so that the helmet is pulled from front to rear.

Sec. 1203.16 Dynamic strength of retention system test.

(a) Test equipment.
(1) ISO headforms without the lower chin portion shall be used.
(2) The retention system strength test equipment shall consist of a
dynamic impact apparatus that allows a 4-kg (8.8-lb) drop weight to
slide in a guided free fall to impact a rigid stop anvil (see Figure 8
of this part). Two cylindrical rollers that spin freely, with a
diameter of 12.5 0.5 mm (0.49 in. 0.02 in.)
and a center-to-center distance of 76.0 1 mm (3.0
0.04 in.), shall make up a stirrup that represents the
bone structure of the lower jaw. The entire dynamic test apparatus
hangs freely on the retention system. The entire mass of the support
assembly, including the 4-kg (8.8-lb) drop weight, shall be 11 kg
0.5 kg (24.2 lb 1.1 lb).
(b) Test procedure.
(1) Place the helmet on the appropriate size headform on the test
device according to the HPI. Fasten the strap of the retention system

(3) Raise the 4-kg (8.8-lb) drop weight to a height of 0.6 m (2 ft)
from the stop anvil and release it, so that it impacts the stop anvil.
(4) Record the maximum elongation of the retention system during
the impact. A marker system or a displacement transducer, as shown in
Figure 8 of this part, are two methods of measuring the elongation.

Sec. 1203.17 Impact attenuation test.

(a) Impact 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 or guidewire test apparatus (see Figure 9 of this part), onto
an anvil fixed to a rigid base. The center of the anvil shall be
aligned with the center vertical axis of the accelerometer. 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 shall be 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 shall be at the center of the mounting
ball on the support assembly and within an inverted cone having its
axis vertical and 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 the
specifications of Federal Motor Vehicle Safety Standard No. 218,
Motorcycle Helmets, 49 CFR 571.218 (S7.1.8). The center of gravity of
the drop assembly shall lie 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 origin of the coordinate axes is at the
center of the mounting ball on the support assembly. The rectangular
volume has no boundary along the z-axis. The positive z-axis is
downward. The x-y-z axes are mutually perpendicular and have positive
or negative designations as shown in Figure 10 of this part. Figure 10
shows an overhead view of the x-y boundary of the drop assembly center
of gravity.
(4) Drop assembly. The combined mass of the drop assembly, which
consists of instrumented test headform and support assembly (excluding
the test helmet), shall be 5.0 0.1 kg (11.00
0.22 lb).
(5) Impact anvils. Impact tests shall be performed against the
three different solid (i.e., without internal cavities) steel anvils
described in this paragraph (a)(5).
(i) Flat anvil. The flat anvil shall have a flat surface with an
impact face having a minimum diameter of 125 mm (4.92 in.). It shall be
at least 24 mm (0.94 in.) thick (see Figure 11 of this part).
(ii) Hemispherical anvil. The hemispherical anvil shall have a
hemispherical impact surface with a radius of 48 1 mm
(1.89 0.04 in.) (see Figure 12 of this part).
(iii) Curbstone anvil. The curbstone anvil shall have two flat
faces making an angle of 105 degrees and meeting along a striking edge
having 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 Figure 13 of this part).
(b) Test Procedure.
(1) Instrument system check (precision and accuracy). 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 a spherical impactor onto an elastomeric test medium (MEP).
The spherical impactor shall be a 146 mm (5.75 in.) diameter aluminum
sphere that is mounted on the ball-arm connector of the drop assembly.
The total mass of the spherical-impactor drop assembly shall be 5.0
0.1 kg (11.0 0.22 lb). The MEP shall be 152
mm (6 in.) in diameter and 25 mm (1 in.) thick, and shall have a
durometer of 60 2 Shore A. The MEP shall be affixed to the
top surface of a flat 6.35 mm (\1/4\ in.) thick aluminum plate. The
geometric center of the MEP pad shall be aligned with the center
vertical axis of the accelerometer (see paragraph (a)(2) of this
section). The impactor shall be dropped onto the MEP at an impact
velocity of 5.44 m/s 2%. (Typically, this requires a
minimum drop height of 1.50 meters (4.9 ft) plus a height adjustment to
account for friction losses.) Six impacts, at intervals of 75
15 seconds, shall be performed at the beginning and end of
the test series (at a minimum at the beginning and end of each test
day). The first three of six impacts shall be considered warm-up drops,
and their impact values shall be discarded from the series. The second
three impacts shall be recorded. All recorded impacts shall fall within
the range of 380 g to 425 g. In addition, the difference between the
high and low values of the three recorded impacts shall not be greater
than 20 g.
(2) Impact sites. Each of helmets 1 through 4 (one helmet for each
conditioning environment) shall impact at four different sites, with
two impacts on the flat anvil and two impacts on the hemispherical
anvil. The center of any impact may be anywhere on or 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. Each of helmets 5 through
8 (one helmet for each conditioning

[[Page 11734]]

environment) shall impact at one site on the curbstone anvil. The
center of the curbstone impacts may be on or anywhere above the test
line. The curbstone anvil may be placed in any orientation as long as
the center of the anvil is aligned with the axis of the accelerometer.
As noted in Sec. 1203.12(d)(1), impact sites, the order of anvil use
(flat and hemispherical), and curbstone anvil sites and orientation
shall be chosen by the test personnel to provide the most severe test
for the helmet. Rivets and other mechanical fasteners, vents, and any
other helmet feature within the test region are valid test sites.
(3) Impact velocity. The helmet shall be dropped onto the flat
anvil with an impact velocity of 6.2 m/s 3% (20.34 ft/s
3%). (Typically, this requires a minimum drop height of 2
meters (6.56 ft), plus a height adjustment to account for friction
losses.) The helmet shall be dropped onto the hemispherical and
curbstone anvils with an impact velocity of 4.8 m/s 3%
(15.75 ft/s 3%). (Typically, this requires a minimum drop
height of 1.2 meters (3.94 ft), plus a height adjustment to account for
friction losses.) 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. See
Subpart C, Sec. 1203.41(b).

Subpart B--Certification

Sec. 1203.30 Purpose, basis, and scope.

(a) Purpose. 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
specified.
(b) Basis. Section 14(a)(1) of the Consumer Product Safety Act
(CPSA), 15 U.S.C. 2063(a)(1), 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)(1) further
requires that the certificate be based either on a test of each product
or on a ``reasonable testing program.'' The Commission may, by rule,
designate one or more of the manufacturers and private labelers as the
persons who shall issue the required certificate. 15 U.S.C. 2063(a)(2).
(c) Scope. The provisions of this subpart apply to all bicycle
helmets that are subject to the requirements of the Safety Standard for
Bicycle Helmets, subpart A of this part 1203.

Sec. 1203.31 Applicability date.

All bicycle helmets manufactured on or after March 11, 1999, 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, as defined in 15 2052(a)(10)
and (14).
(b) Manufacturer means the entity that either manufactured a helmet
in the United States or imported a helmet manufactured outside the
United States.
(c) Private labeler means an owner of a brand or trademark that is
used on a bicycle helmet subject to the standard and that 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
use.
(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(b) to
include importers, 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) Within the requirements set forth in this paragraph (b),
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 and
importers are responsible for ensuring compliance with all requirements
of the standard in subpart A of this part.
(2) As part of the reasonable testing program, the bicycle helmets
shall be divided into production lots, and sample bicycle helmets from
each production lot shall be tested. Whenever there is a change in
parts, suppliers of parts, or production methods, and the change 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 sufficient actions are taken that it is reasonably likely that no
noncomplying bicycle helmets remain in the production lot. All
identified noncomplying helmets in the lot must be destroyed or altered
by repair, redesign, or use of a different material or component, to
the extent necessary to make them conform to the standard.
(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 section
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
(including importers).

(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 March 11, 1999, in the form of a
durable, legible, and readily visible label meeting the requirements of
this section. This label is the helmet's certificate of compliance, as
that term is used in section 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 U.S. CPSC Safety Standard for
Bicycle

[[Page 11735]]

Helmets for Persons Age 5 and Older'' or ``Complies with U.S. CPSC
Safety Standard for Bicycle Helmets for Persons Age 1 and Older
(Extended Head Coverage)'', as appropriate; this label may spell out
``U.S. Consumer Product Safety Commission'' instead of ``U.S. CPSC'';
(2) The name of the U.S. manufacturer or importer responsible for
issuing the certificate or the name of a private labeler;
(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) The telephone number 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 telephone number of the private labeler;
(6) An identification of the production lot; and
(7) The uncoded month and year the product was manufactured.
(c) Coding. (1) The information required by paragraphs (b)(4) and
(b)(6) of this section, and the information referred to in paragraph
(c)(2) 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 code.
(d) Placement of the label(s). The information required by
paragraphs (b)(2), (b)(3), and (b)(5) of this section must be on one
label. 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 U.S. CPSC Safety Standard
for Bicycle Helmets for Persons Age 5 and Older'', or ``Complies with
U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 1 and
Older (Extended Head Coverage)''. The label shall be legible, readily
visible, and placed on the main display panel of the packaging or, if
the packaging is not visible before purchase (e.g., catalog sales), on
the promotional material used with the sale of the bicycle helmet. This
label may spell out ``U.S. Consumer Product Safety Commission'' instead
of ``U.S. CPSC.''
(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 section 14(a) of the CPSA and this section. 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:
(i) The importer is a resident of the United States or has a
resident agent in the United States,
(ii) There are records of such tests required by Sec. 1203.41 of
subpart C of this part, and
(iii) Such records are available to the Commission within 48 hours
of a request to the importer.
(2) Responsibility of importers. Importers that rely on tests by
the foreign manufacturer to support the certificate of compliance
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.
