标准范围

ISO 5660-2:2002规定了一种小规模方法，用于评估在通风良好的条件下暴露在受控辐射加热水平下（有或没有外部点火器）的基本平坦试样的动态产烟率。通过测量燃烧产物流对激光束的衰减来计算烟雾产生率。在整个试验过程中，无论试样是否燃烧，都会记录烟雾遮蔽情况。ISO 5660-2规定的测量系统是ISO 5660-1所述仪器的扩展。因此，ISO 5660-2与ISO 5660-1一起使用。

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.The measurement system prescribed by ISO 5660-2 is an extension of the apparatus described in ISO 5660-1. Therefore, ISO 5660-2 is used in conjunction with ISO 5660-1.
