ASTM F2032-00

Standard Specification for Helmets Used for BMX Cycling

SCOPE
1.1 This specification covers performance requirements for helmets used in BMX cycling. Studies have shown higher risk to the head and face for this sport compared to recreational street riding; therefore this specification requires impact protection over a larger area of the head than Specification F 1447 and the CPSC standard. This specification also provides performance criteria for helmets equipped with chin bars.
1.2 All testing and requirements of this specification shall be in accordance with Test Methods F 1446 except where noted herein.
