Each test frame shall benominally 8.25 ft (2.5 m) by 22 - 24 in.(559 - 610 mm) wideby 2 in. (51 mm) deep, made from 2 by 2 by 3/16 in. (51 by 51by 5 mm) aluminum
25、 or steel angles or equivalent. No screeningor netting shall be attached to the opening of the frames wherethe test specimen is attached. See Fig. 1.6.1.2 Each test shall be conducted using a factory or fieldjoint along the longitudinal centerline of the test specimen,with a longitudinal seam create

27、 closure system (if applicable).6.1.4 The reflective insulation or the radiant barrier speci-mens shall be of a width sufficient to cover the angle framingfor attachment. Specimens shall be placed on the horizontallegs of the angle. See SectionA-Aof Fig. 1. The specimen shallbe attached to each of t

COMMENTARYX1.1 IntroductionIt has been shown that the carefulreplication of realistic fire scenarios is the most appropriatemeans of fire
39、testing of products and systems. However, this isnot always achievable within the confines of a standard testmethod.X1.2 The use of any standard fire test method intrinsicallycarries some limitations, including the source of heat or flame,the specimen size and orientation, the specimen location andt
40、he fire-test-response characteristics measured.X1.3 Fire tests on reflective insulation and sheet radiantbarriers are often conducted by using Test Method E84.X1.3.1 The source of heat and flame in Test Method E84isa set of two gas burners supplying approximately 300 000BTU/h (87.9 kW) onto the test
