The ASTM D523 standard test method provides a procedure for measuring the specular gloss of surfaces at 20°, 60°, and 85° angles of incidence. The test method involves the use of a glossmeter, which is a device that measures the specular gloss of a surface by shining a beam of light on it and measuring the amount of light reflected.

Converts the collected light energy into an electrical signal. The Scale: Gloss Units (GU)

Note: Certain highly reflective metallic surfaces or mirrors can exceed 100 GU because they reflect more light than the black glass reference standard. Step-by-Step Testing Procedure astm d523 pdf new

In the world of coatings, plastics, and surface finishes, the ability to quantify "shininess" is critical for quality control, aesthetic appeal, and functional performance. is the industry-standard method for determining the specular gloss of nonmetallic specimens.

Without this standard, a car door painted in Michigan wouldn't match a fender painted in Mexico.

Every revision updates the repeatability (same operator) and reproducibility (different labs) limits. Using an old PDF means you might be operating under statistical limits that are no longer accepted by major audits (ISO 17025, for example).
