At its core, ASTM D523 provides a standardized procedure for measuring the specular gloss of nonmetallic specimens. "Specular gloss" refers to the surface's ability to reflect light in the mirror-like direction. According to the standard, gloss is associated with the capacity of a surface to reflect more light in directions close to the specular than in others. Measurements obtained by this test method have been shown to correlate well with visual observations of surface shininess made at roughly the corresponding angles.
