标准摘要
[中文适用范围]： 本文件规定了透明、半透明或不透明塑料的总光透射率和总光反射率的测定方法。 样品形状包括模制板或圆盘、薄膜和片材。 本文件不包括荧光塑料和彩色塑料。 注：ISO 13468-1 的范围表明 ISO 13468-1 涵盖平面透明且基本无色的塑料。 本文档中的方法提供了捕获漫射光并覆盖以测量半透明和不透明塑料的方法。 [外文原描述]： This document specifies the determination of total luminous transmittance and total luminous reflectance on clear, translucent or opaque plastics. Specimen shapes include moulded plaque or discs, films and sheets. Fluorescent plastics and chromatic colour plastics are not covered by this document. NOTE The scope of ISO 13468-1 shows that ISO 13468-1 covers planar transparent and substantially colourless plastics. The method in this document provide the way to trap diffused light and covers to measure translucent and opaque plastics.
