1.1 这些测试方法包括实验室设备、程序和与测试防护头盔相关的基本要求。这些试验方法的偏差或添加，或两者都将根据需要在单独的ASTM性能标准中规定。 1.2 要求- 防护头盔应在规定的环境条件下进行以下测试: 1.2.1 防护头盔的冲击衰减（头部加速度限制），以及 1.2.2 固位系统及其与防护头盔的连接的强度和稳定性。 1.2.3 将在与这些试验方法一起使用的单独性能标准中规定特殊防护头盔使用的特殊试验。 1.3 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。 1.4 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====== 5.1 这些测试方法的目的是为评估各种类型的防护头盔提供可靠且可重复的测试。 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 These test methods cover laboratory equipment, procedures, and basic requirements pertinent to testing protective headgear. Deviations or additions, or both, to these test methods will be specified, as required, in individual ASTM performance standards. 1.2 Requirements— The protective headgear is to be tested under specified environmental conditions for the following: 1.2.1 Impact attenuation (the limiting of head acceleration) of the protective headgear, and 1.2.2 Strength and stability of the retention system and its attachment to the protective headgear. 1.2.3 Special tests for particular protective headgear uses will be specified in the individual performance standards to be used in conjunction with these test methods. 1.3 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. 1.4 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 ====== 5.1 The purpose of these test methods is to provide reliable and repeatable tests for the evaluation of various types of protective headgear. 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.
