(25.4 mm).   Measurement is made of the attenuation of a light beam by smoke (suspended solid or liquid particles) accumulating within a closed chamber due to nonflaming pyrolytic decomposition and flaming combustion.   Results are expressed in terms of specific optical density which is derived from a geometrical factor and the measured optical density, a measurement characteristic of the concentration of smoke.  This test method is intended for use in research and development and not as a basis for ratings for regulatory purposes. This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.   The values stated in inch-pound units are to be regarded as standard. Values stated in parentheses are for information only.【中国标准分类号】: C80【国际标准分类号】: 13_220_40;17_180_99【页数】: 【正文语种】: 英语
