1.1 This specification establishes voluntary performance requirements and methods of test for the resistance to forced entry of window and door assemblies. This specification addresses the capability of window and door assemblies to frustrate opportunistic entry by unskilled and semi-skilled intruders.

1.2 These requirements are limited to window and door assemblies only as manufactured, regardless of their materials or method of manufacture. They do not include requirements for secondary or storm windows and doors, doors intended for vehicular access, or skylights. This is a laboratory test, not a field test that simulates an installed condition.
