ASTM D1003: Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics
This test method covers the evaluation of specific light-transmitting and wide-angle-light-scattering properties of planar sections of materials such as essentially transparent plastic
. Two procedures are provided for the measurement of luminous transmittance and haze. Material having a haze value greater than 30 % is considered diffusing and should be tested in accordance with Practice E 167.The values stated in SI units are to be regarded as standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This test method is not equivalent to ISO 13468–1 and ISO/DIS 14782.
