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 in accordance with 
Sec. 1203.17. Table 1203.13 summarizes the test schedule.
