This specification covers performance requirements for helmets used by downhill mountain bicycle riders. Studies have shown higher risk to the head and face for this sport as compared to recreational street riding; hence, this specification requires greater impact protection and provides performance criteria for chin bars on full-face helmets, but does not require full-face helmets. Retention system tests shall be performed before impact testing. The helmet can be impacted anywhere on or above the test line with the curbstone anvil in any horizontal orientation. The ambient test helmet shall be subjected to the chin bar impact test.1.1 This specification covers performance requirements for helmets used by downhill mountain bicycle riders.

4.1 The purpose of these test methods is to provide reliable and repeatable tests for the evaluation of various types of protective headgear when subjected to rotational loading. Use of these test methods in conjunction with the specific individual performance standards is intended to reduce the likelihood of serious injury and death resulting from impacts to the head sustained by individuals participating in sports, recreation, and other leisure activities in which protective headgear is worn.1.1 This test method covers laboratory equipment, procedures, and basic requirements pertinent to testing the performance of helmets during rotational loading using an incline anvil. Deviations and additions to this test method will be specified, as required, in individual ASTM performance standards.1.2 Requirements—The helmet may be tested under one or more specified environmental conditions for impact attenuation (the limiting of impact forces) as a result of a vertical free-fall onto an incline anvil.1.3 Except where noted, the values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This specification covers shock absorption requirements for new and reconditioned football helmets for use in competitive play and practice. The parts of the helmet that will be in contact with the head should not be made of materials that are known to cause irritation or disease. The helmet, as tested, should have no rigid external projections greater than the specified dimension and any faceguard or faceguard hardware installed in the helmet must be removed prior to testing. All allowable external projections should be smooth and rounded while all internal rigid projections that can contact the wearer's head should be adequately protected by cushioning or force spreading. Internal shock-absorbing helmet components should not become detached or loose during impact tests or show any permanent deformation or physical damage.1.1 This specification covers new and reconditioned football helmets intended for use in competitive play and practice with particular reference to shock attenuation requirements.1.2 This specification establishes shock absorption requirements of complete helmets when tested in accordance with Test Method F429 and establishes requirements for construction, materials, visibility, and labeling.1.3 The values stated in SI units are to be regarded as standard.
