Full Description

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.
