NEN-ISO 14782

Plastics - Determination of haze for transparent materials

active, Most Current
Organization: NEN
Publication Date: 1 October 2021
Status: active
Page Count: 16
ICS Code (Plastics in general): 83.080.01
scope:

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.
