                         Subpart A--The Standard
 
Sec.  1203.12  Test requirements.

    (a) Peripheral vision. All bicycle helmets shall allow unobstructed 
vision through a minimum of 105 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.
