ASTM F3279-24

Standard Test Method for Ballistic-Resistant Security Glazing Materials

SIGNIFICANCE AND USE
5.1 This test method provides a basis for the comparative evaluation of the ballistic resistance of security glazing and should not be used to establish or confirm the absolute prevention of damage, harm, or injuries from such attacks.  
5.2 Ballistic threat levels and corresponding test ammunition of historical commercial significance are indicated in Table 1. The description, weights, and velocities have been updated to correspond with available and in-use ammunitions. If a user desires to utilize these threat levels, then the BTI for the corresponding Threat/Performance level needs to be met. Additional threat level(s) and corresponding test ammunition are included in Table X1.1.
SCOPE
1.1 This test method sets forth procedures whose purpose is limited to the evaluation of the resistance of security glazing materials against ballistic threats.  
1.1.1 Glazing tested in accordance with these methods is able to be assigned a ballistic resistant class (BRC) criterion.  
1.1.2 Glazing tested in accordance with these methods is able to be assigned a ballistic test identity (BTI).  
1.1.3 BRC’s by themselves are not indicators of performance ranking. Only the BTI is the performance indicator of ballistic resistance derived from this test method. BRC by itself is not an indication of the complete ballistic resistance performance.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.3 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.  
1.4 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.
