5.1 Within a given period of time, the success or failure of any attempt to forcibly enter a structure intended to resist that entry is dependent upon three primary factors that collectively define the threat: (1) the tools and devices employed, (2) the number of aggressors, and (3) the level of sophistication of the attack.

5.2 The procedures presented herein are based on field experience and are not intended to be used to establish or confirm the absolute prevention of forced entries.

5.3 The test requirements specified herein have been established for use in evaluating the forced-entry resistance characteristics of structures and assemblies to be used in commercial, government, and military installations.

5.4 The procedures of this test method are intended to evaluate the time necessary for personnel to create an opening of sufficient size to permit passage of a test shape through it.

1.1 This test method sets forth the requirements and testing procedures to test forced-entry-resistant building components, construction components, and specialty security equipment. This test method is intended primarily for manufacturers to test and rate their windows, doors, modular panels, glazings, louvers, walls, seismic joints, roofs, roof hatches, grilles, and similar products to ensure that all manufactured products meet the necessary requirements for forced-entry protection.

1.2 This test method is currently designed to simulate a spontaneous mob using readily available hand tools as the primary threat for forced entry.

1.3 In order to receive a rating, all portions of the tested specimen must meet or exceed the test level.

1.4 Systems are required to be tested as complete units in a test frame or fielded conditions. Mulled systems must be tested in the mulled condition. Test results only apply to the component or system as tested. Once a system is tested and deemed to satisfy the requirements of this test method, no design change can be made without a retest.

1.5 Units—The values stated in this standard are SI units with the exception of the nominal descriptors for tools.

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.
