1.1 本标准提供了评估执法和惩戒人员佩戴的头部保护（即头盔和面罩）的非防弹测试方法和调节程序。 1.1.1 包括调节程序，以评估耐化学品和清洁产品、极端温度、风化和液体吸收方面的耐久性。 1.1.2 包括测试方法，以评估对危险的防护性能，包括撞击/撞击、抛射物（子弹除外）、火焰和液体。 1.1.3 测试方法包括评估保持系统强度、头盔在佩戴者头部的稳定性、耐腐蚀性、面罩视力、视野、抗划伤性和抗- 薄雾财产。 注1: 这些试验方法参考了ASTM国际和其他标准制定组织发布的标准。 附录X1 包含本标准中包含的测试方法总结，以及每种方法的来源和目的。 1.2 这些测试方法不涉及除头盔上的面罩外的眼睛保护。 1.3 预计供应商、认证机构、采购商或其他用户将参考这些测试方法，以满足其特定需求。这些用户将在其他标准和规范中指定适用的测试方法和调节程序，并指定任何性能类别或级别。 1.3.1 如果这些测试方法与用户提供的文件之间存在差异，则应以用户提供的文档为准。 1.4 在这些测试方法中，“其他标准和规范”和“除非另有规定”是指要求使用这些测试方法的文件（例如，军事标准、采购规范）。买方和其他用户负责“其他标准和规范”，并负责规定替代这些测试方法的任何要求。 1.5 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准值。 每个系统中所述的值不一定完全相等；因此，为了确保符合标准，每个系统应独立使用，两个系统的值不得合并。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 这些测试方法的目的是为执法和矫正应用中使用的头部保护评估提供可靠且可重复的非冲击性测试方法和调节程序。 4.2 预计这些测试方法将被认证者、购买者或其他用户参考，以满足他们的特定需求。这些用户将指定适用的测试方法和调节程序，并指定任何性能类别或级别。 4.3 这些试验方法包括一些程序和参考其他标准，以确保满足相关财产。

1.1 This standard provides nonballistic test methods and conditioning procedures for assessing head protection (that is, helmet and face shield) worn by law enforcement and corrections officers. 1.1.1 Conditioning procedures are included to assess durability in terms of resistance to chemicals and cleaning products, extreme temperatures, weathering, and absorption of liquids. 1.1.2 Test methods are included to assess the protective performance against hazards including impact/bump, projectiles (other than bullets), flame, and liquids. 1.1.3 Test methods are included to assess safety and ergonomic aspects of retention system strength, stability of the helmet on the wearer’s head, corrosion resistance, and face shield visual acuity, field of view, scratch resistance, and anti-mist properties. Note 1: These test methods reference published standards from ASTM International and other standards developing organizations. Appendix X1 contains a summary of test methods included in this standard, along with the source and purpose for each. 1.2 These test methods do not address eye protection other than face shields that are attached to the helmet. 1.3 It is anticipated that these test methods will be referenced by suppliers, certifiers, purchasers, or other users to meet their specific needs. Those users will specify, in other standards and specifications, which test methods and conditioning procedures are applicable and will specify any performance categories or levels. 1.3.1 If there is a discrepancy between these test methods and a user-supplied document, the user-supplied document shall take precedence. 1.4 In these test methods, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of these test methods. Purchasers and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of these test methods. 1.5 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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 nonballistic test methods and conditioning procedures for the evaluation of head protection used in law enforcement and corrections applications. 4.2 It is anticipated that these test methods will be referenced by certifiers, purchasers, or other users in order to meet their specific needs. Those users will specify which test methods and conditioning procedures are applicable, and will specify any performance categories or levels. 4.3 These test methods include some procedures and references to other standards to ensure that relevant properties are addressed.
