适用范围/摘要
1.1
本试验方法描述了由试验威胁引起的粘土背衬背面变形（BFD）接触测量的试验方法，该测试威胁会在护甲试验项目中产生部分穿透。
1.2
本试验方法适用于平面和非平面软装甲和硬装甲的试验。
1.3
本试验方法不适用于头盔的试验。
1.4
本测试方法的目的是在实验室之间实现一致的测量，并减少使用不同测量技术可能导致的差异。
1.5
预计认证机构、购买者和其他用户将参考该测试方法，以满足其特定需求。
1.6
本试验方法未规定护甲的BFD性能要求。性能要求包含在其他标准或规范中。其他标准或规范中还包括用于确定是否符合规范和考虑不确定性的决策规则。
1.6.1
在本试验方法中，“其他标准和规范”和“除非另有规定”指需要使用本试验方法的文件（例如，军用标准、采购规范）。
认证机构、购买者和其他用户负责“其他标准和规范”，并指定取代本试验方法的任何要求。
1.7
单位-
以国际单位制表示的数值应视为标准值。在适当情况下，括号中提供了到非国际单位制的数学转换，以供参考。
1.8
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。
1.9
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。

本测试方法可适用于认证测试或研发测试。
1.1
This test method describes test methods for the contact measurement of backface deformation (BFD) in clay backing caused by a test threat that produces a partial penetration in a body armor test item.
1.2
This test method is applicable to testing of planar and nonplanar soft armor and hard armor.
1.3
This test method is not applicable to testing of helmets.
1.4
The purpose of this test method is to achieve consistent measurements between laboratories and reduce differences that could result from using different measurement techniques.
1.5
It is anticipated that this test method will be referenced by certifiers, purchasers, and other users in order to meet their specific needs.
1.6
This test method does not specify BFD performance requirements for body armor. The performance requirements are included in other standards or specifications. The decision rules for determining conformance to specifications and the consideration of uncertainty are also included in other standards or specifications.
1.6.1
In this test method, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of this test method. Certifiers, purchasers, and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of this test method.
1.7
Units—
The values stated in SI units are to be regarded as standard. Where appropriate, mathematical conversions to non-SI units are provided in parentheses for informational purposes.
1.8
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.
1.9
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
U.S. Department of Defense and U.S. Department of Justice standards for assessing the performance of ballistic-resistant torso body armor require the measurement of BFD on backing assemblies made with
