The latest version of the primary international standard for measuring surface shininess is , approved in June 2025 . This standard defines a rigorous methodology for quantifying "specular gloss"—the ability of a nonmetallic surface to reflect light in a mirror-like direction.

The ASTM D523-25 standard is not just about measuring light; it is about ensuring that instrumental results correlate with human visual perception. The significance and use section of the standard explicitly states that measurements from this method correlate with visual observations of surface shininess made at roughly the corresponding angles. This is crucial because, in many industrial and manufacturing settings, visual quality is the ultimate criterion. The standard provides an objective, repeatable, and reproducible way to quantify that subjective assessment. astm d523 pdf new

Gloss tests are executed using specialized devices known as gloss meters . Modern instruments—such as the PosiTector GLS Gloss Meter or BYK-Gardner units—automate this process, using single or multiple angles to take readings in under a second.
