This standard is used to measure the relative luminous reflectance (gloss) of nonmetallic surfaces using three specific geometries: 20° Geometry : Used for high-gloss

Elena looked at the readout on the screen. The car was a 1967 Corvette Stingray, a vehicle that left the factory with a very specific, deep luster. The reading on the screen showed a Gloss Units (GU) value of 92 at a 20-degree angle. It was practically mirror-like. Too mirror-like. This standard is used to measure the relative

The latest standard adds definitions for terms like "specular reflectance factor" and clarifies the difference between "gloss units" (GU) and percent reflectance. The reading on the screen showed a Gloss

Based on interlaboratory tests from 2023, the new standard provides updated repeatability limits (r) and reproducibility limits (R). For example, for 60° gloss on paint:

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
