ISO 5660-2: Reaction to fire tests -- Heat release, smoke production and mass loss rate -- Part 2: Smoke production rate (dynamic measurement)
Abstract摘要
ISO 5660-2:2002 specifies a small-scale method for assessing the dynamic smoke production rate of essentially flat specimens exposed to controlled levels of radiant heating under well-ventilated conditions with or without an external igniter. The rate of smoke production is calculated from measurement of the attenuation of a laser light beam by the combustion product stream. Smoke obscuration is recorded for the entire test, regardless of whether the specimen is flaming or not.
