ISO 14782:1999 塑料 透明材料雾度的测定

标准编号：ISO 14782:1999

中文名称：塑料 透明材料雾度的测定

英文名称：Plastics — Determination of haze for transparent materials

发布日期：1999-08

标准范围

本国际标准规定了测量雾度的方法，雾度是由在透明且基本无色的塑料中，光的广角散射。此方法适用于测量小于40%的雾度值。注:可以测量磨损或磨砂透明塑料的雾度，但获得的值可能有误由于窄角度内的光散射，低于真实值。

This International Standard specifies a method for the measurement of haze, an optical property resulting fromwide-angle scattering of light, in transparent and substantially colourless plastics. This method is applicable to themeasurement of haze values of less than 40 %.NOTE The haze of abraded or matted transparent plastics can be measured, but the value obtained may be erroneouslylower than the true value due to light scattering within a narrow angle.
