1.1 本规程仅适用于在弹道阻力测试之前通过温度、湿度和翻滚暴露对软护甲进行调节。 1.2 本规程适用于执法应用中的软装甲，其目的是使测试项目处于旨在提供测试项目承受磨损过程中可能遇到的高温、潮湿和机械磨损（折叠和磨损）的能力的一些指示的条件下。 1.2.1 本规程不适用于军事应用中使用的软装甲。 1.3 在本实施规程中，“其他标准和规范”和“除非另有规定”指要求使用本实施规程的文件。 购买者和其他用户负责“其他标准和规范”，并指定取代本规范的任何要求。 1.4 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。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.5 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。 1.6 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 U、 美国司法部评估抗弹道躯干防弹衣性能的标准要求在弹道测试之前对软装甲测试项目进行调节。 4.2 该实践方法可适用于认证测试或研发测试。 4.3 本规程仅针对抗弹道护甲进行了评估，尚未评估其是否适用于任何其他类型的防护系统。

1.1 This practice applies only to the conditioning of soft body armor via temperature, humidity, and tumbling exposure prior to ballistic resistance testing. 1.2 This practice is intended for soft armor for law enforcement applications, and its purpose is to subject test items to conditions intended to provide some indication of the test item ability to withstand conditions of heat, moisture, and mechanical wear (folding and abrasion) that might be encountered during wear. 1.2.1 This practice is not intended for soft armor to be used in military applications. 1.3 In this practice, “other standards and specifications” and “unless specified elsewhere” refer to documents that require the use of this practice. Purchasers and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of this practice. 1.4 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. 1.5 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. 1.6 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 U.S. Department of Justice standards for assessing the performance of ballistic-resistant torso body armor require conditioning of soft armor test items prior to ballistic testing. 4.2 This practice method may be applicable for certification testing or for research and development testing. 4.3 This practice has only been evaluated for ballistic-resistant body armor and has not been assessed for applicability to any other type of protective system.
