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.
Abstract
Overview
ISO 14782:2021 - Plastics: Determination of haze for transparent materials specifies a standardized laboratory method to measure haze, the optical effect caused by wide-angle scattering of light, in transparent and substantially colourless plastics. The method is designed for haze values below 40% and describes required apparatus, specimen preparation, conditioning, test procedure and how to express results. The standard replaces ISO 14782:1999 and incorporates technical corrections and editorial updates.
