ASTM E1995煙密不透明度測試-標準名稱
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 用單獨密閉室圓錐形輻射源和水平導向試樣測量煙霧不透明度的試驗方法
ASTM E1995煙密不透明度測試-標準簡介
ASTM E1995這是一個材料對火反應的測試標準。本測試方法提供了一種測量煙霧不透明度的方法，其主要測量對象為平面材料、產品或組件(包括表面飾面)，且不超過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
