ASTM E1995 Standard Test Method for Measurement of Smoke Obscuration Using a Conical Radiant Source in a Single Closed Chamber, With the Test Specimen Oriented Horizontally

ASTM E1995  用单独密闭室圆锥形辐射源和水平导向试样测量烟雾不透明度的试验方法

 

ASTM E1995这是一个材料对火反应的测试标准。本测试方法提供了一种测量烟雾不透明度的方法，其主要测量对象为平面材料、产品或组件(包括表面饰面)，且不超过25毫米[1英寸]。

 

ASTM E1995 This is a fire-test-response standard.This test method provides a means of measuring smokeobscuration resulting from subjecting essentially flat materials,products, or assemblies (including surface finishes), not ex- ceeding 25 mm [1 in. in thickness, in a horizontal orientation, exposed to specified levels of thermal irradiance, from aconical heater, in the presence of a pilot flame, in a singleclosed chamber. Optional testing modes exclude the pilotflame.The principal fire-test-response characteristic obtainedfrom this test method is the specific optical density of smokefrom the specimens tested, which is obtained as a function oftime, for a period of 10 min.An optional fire-test-response characteristic measurable.with this test method is the mass optical density
