(Test Method)Standard Test Method for Blast Resistance of Trash Receptacles
Standard Test Method for Blast Resistance of Trash Receptacles
SIGNIFICANCE AND USE
5.1 This test procedure is used to measure two of the main effects of an explosive detonated in a trash receptacle as related to the type and amount of explosive charge and the location where the charge is placed in the trash receptacle. The two effects are:
5.1.1 Release of primary and secondary fragments, and
5.1.2 Physical damage to the trash receptacle.
5.2 This test procedure is applicable to all trash receptacles, including lidded or non-lidded as supplied by the manufacturer.
5.3 This test procedure is used to generate data for use in developing performance specifications for trash receptacles.
5.4 For users having interest in determining overpressures created by the detonation, Appendix X1 provides guidance for making such determinations.
SCOPE
1.1 This test method provides a procedure for characterizing the performance of a trash receptacle when an explosive is detonated within the receptacle.
1.1.1 The procedure determines the extent and location of fragments produced during the explosion, and whether breaches are created in the exterior surfaces of the trash receptacle.
1.1.2 Appendix X1 provides guidance for determining the magnitude of blast waves (that is, external overpressures) developed.
1.1.3 Effects due to a fireball resulting from the detonation of an explosive within a trash receptacle are beyond the scope of the test method.
1.2 This test method is intended to be performed in open-air test arenas.
1.3 The values stated in SI units are to be regarded as the standard. The values stated 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
