Standard Specification for Helmets Used for BMX Cycling

ABSTRACT
This specification covers performance requirements for helmets used in BMX cycling. Studies have shown higher risk to the head and face for this sport as compared to recreational street riding; So this specification requires impact protection over a larger area of the head. Performance criteria for helmets equipped with chin bars are provided. Retention system tests shall be performed before impact testing. The chin bar rigidity test applies to helmets with a chin bar only.
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 as compared to recreational street riding; therefore, this specification requires impact protection over a larger area of the head than Specification F1447 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 F1446 except where noted herein.
1.3 Partial utilization of this specification is prohibited. Any statement of compliance with this specification shall be a certification that the headgear with faceguard meets all of the requirements of the specification in their entirety. A headgear with faceguard that fails to meet any one of the requirements of this specification is considered to have failed the specification, and shall not be sold with any indication that it meets parts of the specification.
1.4 Headgear designed to comply with this and other standards may proclaim uses as certified by the manufacturer.
1.5 The values stated in SI units are to be regarded as standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
