Anotation

This specification covers performance requirements for helmets manufactured for use by recreational bicyclists or roller skaters. This specification recognizes the desirability of lightweight construction and ventilation; however, it is a performance standard and is not intended to restrict design. Helmets shall be impacted with anvils centered on or above the prescribed test line. The test anvils can be oriented in any horizontal, centered position. One each hot, cold, wet, and ambient helmet shall be impacted using the flat and hemispherical anvils only. The curbstone anvil shall be used to impact one time each of the second set of four samples, one conditioned under each of the four conditioning environments. The peak acceleration of the impulse during the impact shall be measured. The ambient helmet shall be subjected to the positional stability (roll-off) test, while the hot, cold, and wet helmets shall be subjected to the dynamic strength retention test.
