Used for "sheen" or near-grazing shininess on dull surfaces (60° gloss values lower than 10 units). Common Applications
The industry benchmark for quantifying this visual property is : Standard Test Method for Specular Gloss . For engineers, lab technicians, and procurement managers, finding a legitimate, up-to-date version of the "astm d523 pdf" is a constant necessity.
1.1 This test method covers the measurement of the specular gloss of non-metallic painted surfaces only, such as painted metal, plastic, and wood. 1.2 This test method is designed to measure the specular gloss of surfaces at specified angles of illumination and view.
Specifically, it covers the measurement of the specular gloss of non-metallic specimens for gloss-meter geometries of 20°, 60°, and 85°. It is the most widely cited standard for gloss measurement across a vast array of industries, including:
ASTM D523 quantifies this by measuring the amount of light reflected at a specific angle relative to the amount of light incident (incoming).
When you search for the , you are looking for the instruction manual that ensures everyone in the global supply chain is speaking the same visual language.
8.1 The glossmeter is positioned on the test specimen, ensuring that the light source and receptor are at the specified angles (usually 20°, 60°, or 85°). 8.2 The gloss value is read directly from the glossmeter.
