ISO TR5659-3塑料烟雾透光性测试–标准概述

ISO5659的这一部分规定了一种方法，用于测量在水平方向放置、在强制通风条件下受到指定水平的热辐照度时，从基本平坦材料、复合材料或厚度不超过25毫米的组件的样品的暴露表面产生的烟雾。有或没有引燃火焰。这种测试方法适用于塑料，也可用于其他材料的评估(如橡胶、纺织覆盖物、油漆表面、木材和其他建筑材料)。

Scope:

Thispart of ISO 5659 specifies a method of measuring smoke production from theexposed surface of specimens of essentially flat materials, composites orassemblies not exceeding 25 mm in thickness, when placed in a horizontalorientation and subjected to specified levels of thermal irradiance underforced ventilation conditions. with or without the application of a pilotflame. This method of test is applicable to plastics and may also be used forthe evaluation of other materials (e.g. rubbers, textile coverings, paintedsurfaces, wood and other building materials).
