The ASTM 430-97-2003 "Determination of Gloss on High Gloss Surfaces by Angle Measuring Light Spectrum Instrument" stipulates the standard method for the determination of Glossiness on high Gloss surfaces by angle measuring Light spectra. The standard clarifies the technical parameters and calibrating requirements of the instrument, standardizes the preparation and measurement process of the sample, and accurately quantifies the Gloss characteristics of high Gloss surfaces through measurement and analysis of Reflection spectra at different angles. It provides a unified testing standard and technical basis for scientifically evaluating the surface mass of high Gloss materials and ensuring the appearance conformity of products.
