The ASTM D523 standard test method provides a procedure for measuring the specular gloss of surfaces at 20°, 60°, and 85° angles of incidence. The test method involves the use of a glossmeter, which is a device that measures the specular gloss of a surface by shining a beam of light on it and measuring the amount of light reflected.
