ASTM F3555-22 - Standard Test Method for Measuring Impact Attenuation Characteristics of Helmets Under Induced Rotational Loading Using an Inclined Anvil

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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
