1.1 本规程适用于防弹试验前硬装甲试验项目的调节。硬甲是一种由硬质材料制成的个人防护装备，旨在保护穿戴者免受可能包括弹道威胁、刺伤、碎裂或钝性冲击或其组合的威胁。（术语 2005年 硬装甲也称为硬装甲板和钢板。 注1: 本规程不包括弹道阻力测试。 1.2 本规程描述了对测试项目进行条件测试的要求，该条件旨在评估测试项目承受环境条件的能力，该环境条件会导致与使用过程中遇到的条件类似的反应。 本规程包括下列调节程序: 1.2.1 受控环境调节程序， 1.2.2 热/温度冲击程序， 1.2.3 温度极限程序， 1.2.4 风化程序， 1.2.5 流体暴露程序， 1.2.6 高度暴露程序， 1.2.7 振动调节程序， 1.2.8 冲击耐久性预处理， 1.2.9 躯干前板和背板的冲击耐久性程序，以及 1.2.10 其他板（即，躯干前板和背板除外）的冲击耐久性程序。 1.3 本规程的使用者应确定适用的调节程序。 注2: 本规程可能不适用于所有类型的硬装甲。 1.4 在本规程中，“其他标准和规范”和“除非另有规定”是指需要使用本规程的文件（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”，并负责规定替代本规范的任何要求。 1. 5. 本规程不涉及这些程序中测试项目的合格/不合格要求。 1.6 本规程不涉及调节前或调节后可能需要的试验项目的目视检查或射线检查。 注3: 建议在暴露前后对每个测试项目进行彻底的目视检查，以记录暴露导致的任何物理外观变化。 1.7 本规程不涉及测试项目的后续调节或测试。 1.8 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。 1.8.1 本标准的用户将确定要使用的单位系统，确保任何交叉引用的标准保持标准之间单位的一致性至关重要。 1.9 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。 1.10 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 预计认证者、购买者和其他用户将参考该实践，以满足其特定需求。这些用户将指定适用的调节程序。

1.1 This practice applies to the conditioning of hard armor test items prior to ballistic resistance testing. Hard armor is an item of personal protective equipment that is constructed of rigid materials and is intended to protect the wearer from threats that may include ballistic threats, stabbing, fragmentation, or blunt impact, or combinations thereof. (Terminology E3005 .) Hard armor is also referred to as hard armor plate and plate. Note 1: Ballistic resistance testing is not covered in this practice. 1.2 This practice describes requirements for subjecting test items to conditions intended to assess the capability of the test item to withstand environmental conditions that induce responses similar to those that might result from conditions encountered during use. This practice includes the conditioning procedures listed below: 1.2.1 Controlled ambient conditioning procedure, 1.2.2 Thermal/temperature shock procedure, 1.2.3 Temperature extremes procedure, 1.2.4 Weathering procedure, 1.2.5 Fluid exposure procedure, 1.2.6 Altitude exposure procedure, 1.2.7 Vibration conditioning procedure, 1.2.8 Impact Durability pre-conditioning, 1.2.9 Impact Durability procedure for torso front and back plates, and 1.2.10 Impact Durability procedure for other plates (that is, other than torso front and back plates). 1.3 The user of this practice shall determine which conditioning procedures apply. Note 2: This practice may not be applicable to all types of hard armor. 1.4 In this practice, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) 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. 1.5 This practice does not address pass/fail requirements for test items subjected to these procedures. 1.6 This practice does not address visual inspections or radiographic inspections of test items that may be required prior to or following conditioning. Note 3: It is recommended that a thorough visual examination of each test item prior to and after the exposures be performed to document any change in physical appearance resulting from the exposure. 1.7 This practice does not address subsequent conditioning or testing of test items. 1.8 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. 1.8.1 The user of this standard will identify the system of units to be used, and it is critical to ensure that any cross-referenced standards maintain consistency of units between standards. 1.9 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. 1.10 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 It is anticipated that this practice will be referenced by certifiers, purchasers, and other users in order to meet their specific needs. Those users will specify which conditioning procedures are applicable.
