    1. Scope

    1.1 This test method evaluates the fire-test response characteristics of a building perimeter containment system installed at the intersection of a floor assembly and the exterior wall of a building. 1.2 This test method is used to assess the building perimeter containment systems ability to impede vertical fire spread into higher floors from the room of origin in multi-story buildings via fire spread on the exterior of a building and provide a quantitative measure of the fire hazard from a specified set of fire conditions involving specific materials, products, or assemblies. 1.3 This test method evaluates the performance of the portion of the exterior wall installed between vertically adjacent window openings in multi-story buildings. 1.3 The test method simulates a fire in a post-flashover condition in a compartment that is venting to the exterior through a window opening. 1.4 The fire exposure conditions within in the test room are those specified by this test method for the first 30 min of exposure and then conform to Test Methods E119 time-temperature curve for the remainder of the test. The fire exposure on the exterior surface of the test specimen comprises both the exposure from the fire plume exiting the window opening of the test room and the exterior burner. 1.5 This test method specifies the heating conditions, methods of test, and criteria for evaluation of the buildings perimeter containment system. Specimens are not tested using any superimposed axial load. 1.6 Test results establish the performance of the perimeter containment system during the fire-exposure period and shall not be construed as having determined the suitability of a perimeter containment system for use after that exposure. 1.7 This test method does not provide quantitative information about the perimeter containment system relative to the rate of leakage of smoke or gases or both. 1.7.1 This test method does not evaluate the fire-test-response characteristics of perimeter joint protection between the floor assembly and the exterior wall assembly. This is covered in Test Method E2307. 1.8 This test method is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions but does not by itself incorporate all factors required for the fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire conditions. 1.9 Units--The values stated in inch-pound units are to be regarded as the standard. Where provided, the SI values given in parentheses are for information only. 1.10 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.11 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. 1.12 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be used in conducting these tests.
