The ASTM C346-1987 (2018) standard specifies a method for the determination of 45 degree specular gloss of Pottery and porcelain materials. This method is suitable for enamel samples and Miscellaneous materials with similar reflection characteristics. It can be used to compare the gloss of different Pottery and porcelain products, or to evaluate their acid resistance and wear resistance performance through gloss loss. The test involves the measurement of the ratio of reflected light intensity of the sample to the standard plate under specific conditions to determine the gloss value of the sample. This standard does not cover all safety issues, and it is up to the user to determine the applicability of safety and health practices.
