    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 ROMA Plastilina No. 1®.

    5.2 This test method may be applicable for certification testing or for research and development testing.

    1. Scope

    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.

    1.7 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 and health 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.
