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 created in the approximate centerlineusing the same method of

Thespecimen shall be attached to each of the horizontal legs usingself-tapping screws, through bolts or similar fastening tech-nique. Fastener

COMMENTARYX1.1 IntroductionIt has been shown that the carefulreplication of realistic fire sce
47、narios is the most appropriatemeans of fire 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
48、 and orientation, the specimen location andthe fire-test-response characteristics measured.X1.3 Fire tests on reflective insulation, sheet radiantbarriers and vinyl stretch ceiling materials are often conductedby using Test Method E84.X1.3.1 The source of heat and flame in Test Method E84 isa set of
49、 two gas burners supplying approximately 300 000BTU/h (87.9 kW) onto the test specimen from underneath fora period of 10 min.X1.3.2 The approximate specimen sizes in Test Method E84are 24 ft (7.3 m) long by 20 to 24 in. (510-610 mm) wide. Therecommended specimen thickness is up to 4 in. (102 mm)thick.X1.4 The mounting method using the 2 in. (51 mm) air gapis applicable for materials installed over open framing or whenthe materials are mechanically installed against a substrate.ASTM International takes no position respecting the validity of any patent rights asserted
