Plastics — Determination of haze for transparent materials ISO 14782:1999

Publication date:   Aug 26, 1999

Scope

This International Standard 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 may be erroneously
lower than the true value due to light scattering within a narrow angle.
