This test method provides a quantitative way to measure how "shiny" or reflective a surface is. By using a calibrated glossmeter, manufacturers can assign a numerical value—recorded in —to a surface's reflective capacity. The Latest Update: ASTM D523-25
The ASTM D523 standard has several applications across various industries:
"Proprietary is code for 'I made it up,'" Elena snapped. "We can’t fight that in court without a standard anchor. We need to prove exactly what the factory specification was and exactly how that deviates."

"Matte finish," Marcus whispered. "They didn't repaint it. They sanded it down to the primer to fix a scratch and sprayed a cheap, high-gloss lacquer over it. It looks shiny to the eye, but under the ASTM standard... it’s dull as dirt."
If you can tell me the you are testing, I can give you more detailed advice on which angle to prioritize (20, 60, or 85). D523 Standard Test Method for Specular Gloss - ASTM

"He’s already filed his report," Marcus said, tapping the screen. "He claims the high gloss is due to a 'rare polymerization of the original nitrocellulose.' He says he tested it using... get this... a proprietary method."
Short sample paragraph you can use or adapt "ASTM D523 specifies the procedure for measuring specular gloss of nonmetallic paint films and related coatings at defined geometries (commonly 20°, 60°, and 85°). The method details instrument calibration, sample conditioning, measurement repetition and reporting so that gloss values (in gloss units, GU) are reproducible and comparable across labs. Users should reference the latest revision of the standard (D523‑YYYY) for updated precision data and any procedural clarifications; the official PDF is available from ASTM International."
