1.1 本试验方法涵盖实验室设备、程序和与使用倾斜砧在旋转载荷期间测试头盔性能相关的基本要求。根据需要，本试验方法的偏差和增加将在单独的ASTM性能标准中规定。 1.2 要求- 头盔可以在一个或多个规定的环境条件下进行测试，以确定垂直自由落在倾斜砧上时的冲击衰减（冲击力的限制）。 1.3 除非另有说明，否则以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 这些试验方法的目的是提供可靠且可重复的试验，以评估受到旋转载荷时的各种类型的防护头盔。 将这些测试方法与具体的个人表现标准结合使用，旨在降低因参加运动、娱乐和其他佩戴防护头盔的休闲活动的个人头部受到冲击而导致严重受伤和死亡的可能性。

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. ====== Significance And Use ====== 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.
