Significance and Use
4.1 This practice shall be followed for blast testing with an aim toward maximizing the consistency and repeatability between blast tests and test facilities. Specific requirements include test configuration, instrumentation, test result processing, data reductions, facility requirements, clearing effects, and fixturing or reaction structure design.
4.2 In this practice, inconsistencies in blast testing methodology are reduced and blast testing reporting (interpretation and documentation of blast results) is standardized. This improved consistency of practice will facilitate direct comparison of results, testing repeatability, and identification of trends.
4.3 This practice shall apply to blast simulator testing where applicable, including all aspects of the specification except those that are specific to open air explosive testing.
4.4 Uses—This practice in total is required for open air blast tests and applicable sections are required for blast simulator tests. Any deviation or exception to the practice should be addressed as early in the planning stage as possible and shall require written approval by the AHJ.
Scope
1.1 Purpose—The primary purpose of this practice is to define good commercial and customary practice for conducting blast tests of physical security products, related devices, and systems. The goal is to harmonize results between test facilities and maximize the consistency and repeatability of the results obtained from these blast tests. This practice shall be used for blast simulator testing, where applicable.
1.2 Objectives—Objectives guiding the development of this practice are:
1.2.1 Formalize standard practices for conducting blast tests.
1.2.2 Facilitate high-quality, standardized results processing and reporting of test results.
1.2.3 Use as a starting point for a best practice standard that will grow into an industry standard both domestically and internationally.
1.2.4 It is anticipated that this practice will evolve over time as requirements and facility capabilities change.
1.2.5 This practice should not be considered the limit of requirements for proper completion of a given test program. There may be additional requirements depending on the application and the threat.
1.3 Units—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.
1.4 Omissions—The omission of any specific explosive, instrumentation type, material type, or test configuration does not necessarily preclude its use in accordance with this practice, as long as all applicable provisions are satisfied.
1.5 The following is a table of contents for this practice:
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.
