标准摘要
[中文适用范围]： 该文件规定了一种测量雾度的方法，雾度是透明且基本无色的塑料中由光的广角散射产生的光学特性。 该方法适用于雾度值小于40%的测量。 注：可以测量磨损或无光泽的透明塑料的雾度，但由于窄角度内的光散射，所获得的值可能会错误地低于真实值。 [外文原描述]： This document specifies a method for the measurement of haze, an optical property resulting from wide-angle scattering of light, in transparent and substantially colourless plastics. This method is applicable to the measurement of haze values of less than 40 %. NOTE The haze of abraded or matted transparent plastics can be measured, but the value obtained can be erroneously lower than the true value due to light scattering within a narrow angle.
