ASTM E1995烟密度及毒性测试方法-适用范围

This is a fire-test-response standard. This test method provides a means of measuring smoke obscuration 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 single closed chamber. Optional testing modes exclude the pilot flame.

The principal fire-test-response characteristic obtained from this test method is the specific optical density of smoke from the specimens tested, which is obtained as a function of time, for a period of 10 min. An optional fire-test-response characteristic measurable.with this test method is the mass optical density which is the specific optical density of smoke divided by the mass lost by the specimens during the test.
