Section III-1118 - Retention System Test

A. The retention system test shall be conducted by applying a static tensile load to the retention assembly of a complete helmet, which is mounted, as described in §1114, on a stationary test headform as shown in §1131. E Figure 4, and by measuring the movement of the adjustable portion of the retention system test device under tension.

B. The retention system test device shall consist of both an adjustable loading mechanism by which a static tensile load can be applied to the helmet retention assembly as a means for holding the test headform and helmet stationary. The retention assembly shall be fastened around two freely moving rollers, both of which shall have a 0.5 inch (1.3 cm) diameter and a 3 inch (7.6 cm) center-to-center separation, and which shall be mounted on the adjustable portion of the tensile loading device (Figure 4). The helmet shall be fixed on the test headform as necessary to ensure that it will not move during the application of the test loads to the retention assembly.

C. A 50-pound (22.7 kg) preliminary test load shall be 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 shall be measured.

D. An additional 250-pound (113.4 kg) test load shall be applied to the retention assembly, in the same manner and at the same location as described in §1118 C, 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 shall be measured.
