Sec.  1203.12  Test requirements.

    (a) Peripheral vision. All bicycle helmets shall allow unobstructed 
vision through a minimum of 105[deg] to the left and right sides of the 
midsagittal plane when measured in accordance with Sec.  1203.14 of this 
standard.
    (b) Positional stability. No bicycle helmet shall come off of the 
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.
    (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.
