1、Designation: E906/E906M 10An American National StandardStandard Test Method forHeat and Visible Smoke Release Rates for Materials andProducts Using a Thermopile Method1This standard is issued under the fixed designation E906/E906M; the number immediately following the designation indicates the yearo
2、f original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method provides for determining the releaserate
3、s of heat and visible smoke (Note 1) from materials,products, or assemblies when exposed to different levels ofradiant heat.NOTE 1Visible smoke is described in terms of the obscuration oftransmitted light caused by combustion products released during the tests(see 14.2.1).1.2 This fire-test-response
4、 method assesses heat release by athermal method, thermopile, using a radiant heat sourcecomposed of an array of four electrical resistance elements.1.3 This test method provides for radiant thermal exposureof a specimen both with and without a pilot. Piloted ignitionresults from direct flame imping

8、, or codepurposes.1.8 The apparatus described in this test method has beenused in two configurations. Configuration A is that which isused by the Federal Aviation Administration for assessingmaterials for aircraft use, at an external heat flux of 35 kW/m2(DOT/FAA/AR-00/12), while configuration B is

10、ibed in 1.9.1-1.9.5.1.9.1 Heat and smoke release rates depend on a number offactors, including the formation of surface char, the formationof an adherent ash, sample thickness, and the method ofmounting.1.9.2 Heat release values are a function of the specificspecimen size (exposed area) tested. Resu
11、lts are not directlyscaleable to different exposed surface areas for some products.1.9.3 The test method is limited to the specified specimensizes of materials, products, or assemblies. If products are to betested, the test specimen shall be representative of the productin actual use. The test is li
12、mited to exposure of one surface; theoptions for exposed surface are vertical and horizontal facingup.1.9.4 At very high specimen heat release rates, it is possiblethat flaming is observed above the stack, which makes the testinvalid.1.9.5 No general relationship has been established betweenheat rel
13、ease rate values obtained from horizontally and verti-cally oriented specimens. Specimens that melt and drip in thevertical orientation shall be tested horizontally.1.10 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system
14、 may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.11 Fire testing of products and materials is inherentlyhazardous, and adequate safeguards for personnel and propertysha
