ASTM F1641-95

Standard Test Method for Measuring Penetration Resistance of Security Glazing Using a Pendulum Impactor (Withdrawn 2004)

SCOPE
1.1 This test method covers the determination of a relative measure of penetration resistance of glazing materials subject to a specific mechanized test. The test simulates a specific attack scenario involving repeated impacts from a chisel-nosed weapon applied either in conjunction with a directed application of heat (Method A), or without directed application of heat (Method B). The resulting number of impacts required to achieve a perforation is used to evaluate the degree of penetration resistance provided by the sample.  
1.2 This test method may be specified to implement either Method A or Method B, or both.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 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.
