GB/T 9754-2007 "Determination of 20 °, 60 ° and 85 ° specular gloss of Paints and varnish Paints film without metal pigment" standard specifies the use of 20 °, 60 ° and 85 ° angle measurement of specular gloss of Paints film without metal pigment. This standard is applicable to evaluate the surface Gloss of paint film, by comparing the luminous flux of paint film reflection at different angles to determine its specular gloss value. Geometry conditions of Light source and receiver are emphasized in the standard, ensuring accuracy and comparability of measurement results. In addition, the standard also specifies that Gloss determination methods are not suitable for paint films containing metallic pigments. The publication of this standard aims to provide a standardized method for measuring and comparing specular gloss of Paints and varnish films without metallic pigments in industrial and quality control processes to ensure conformity and Reliability of product mass and performance.
