is the standard test method for measuring the specular gloss of nonmetallic specimens. It is, in essence, the "science of shine".
The ASTM D523 standard specifies three unique measurement angles (geometries). Each geometry is optimized for a specific range of surface gloss. Using the wrong angle can lead to inaccurate data compression and poor quality control.
: Place the glossmeter on the surface. For better accuracy, take multiple readings across different areas of the specimen to account for any surface non-homogeneity.
