: Used for most samples. If the result is between 10 and 70 Gloss Units (GU), stick with this angle. 20° (High Gloss) : Used if the 60° reading is above 70 GU . It provides better resolution for very shiny surfaces. 85° (Low Gloss/Matte) : Used if the 60° reading is below 10 GU astm d523 pdf new
In the world of materials science and quality control, surface appearance is often the first indicator of product quality. Whether you are manufacturing automotive paint, furniture varnish, printing inks, or plastic components, measuring specular gloss is non-negotiable. The gold-standard test method for this measurement is .
She needed the latest revision. The 2018 standard had been updated recently regarding the geometry of the incident beam—crucial when measuring curved surfaces like a Corvette fender. If she used the old standard, Thorne would tear her apart on cross-examination.

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.
