1.1 This test method2 applies to personal protective ballistic-resistant shields. 1.2 The intent of this test method is to evaluate the ballistic resistance of shield products for law enforcement. 1.3 Certifiers, purchasers, and other users of this test method will specify the ballistic test threats to be used. Within this test method, the reference defining the ballistic test threats will be called the “test threats document.” 1.4 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. 1.5 Units—Values stated in either the International System of Units (metric) or U.S. Customary units (inch-pound) are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Tests conducted using either system maintain repeatability and reproducibility of the test method and results are comparable. 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.
