Updated PDFs contain current references to related standards, such as ASTM D523 - 14(2021), which was the standard as of early 2026 [2]. Applications of ASTM D523
The glossmeter must be calibrated using a highly polished, clean black glass standard tile provided by the manufacturer. astm d523 pdf new
in your lab? If you tell me what type of material or coating you are evaluating , I can help you determine the exact geometry required by the ASTM standard. D523 Standard Test Method for Specular Gloss - ASTM
When a 60° measurement yields a gloss value higher than 70 GU, the surface is highly reflective. Switching to the 20° geometry provides enhanced contrast and better differentiation between highly reflective samples (e.g., automotive clear coats or polished metals). 3. The 85° Geometry (The Low-Gloss/Matte Angle) Target Surfaces: Low-gloss or matte materials.
Specular gloss is a measure of the mirror-like appearance of a surface. It is defined as the ratio of the amount of light reflected by a surface to the amount of light incident on it, at a specific angle. Specular gloss is an important property of surfaces, as it can affect their appearance, durability, and functionality. : Results are typically exported as PDF or
Performing a test according to ASTM D523 requires a calibrated glossmeter. The standard places significant emphasis on the correct calibration and verification of this equipment to ensure repeatable results.
