The official "Scope" section of the ASTM D523-25 standard provides the framework for its application:
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). astm d523 pdf new

In this post, we’ll break down the latest updates to ASTM D523, the testing methods, and how you can get your hands on the official documentation to perfect your surface analysis. What is ASTM D523? but in the lab
Elena looked out the window at the slick, wet streets of Seattle. The city was a chaotic mess of light and shadow, but in the lab, the numbers never lied—as long as you knew the rules.
Ratings obtained through this test method are meant to correlate directly with visual observations of surface shininess. The Three Geometries of Gloss Measurement
Consumer electronics and packaging utilize specific gloss profiles to convey a premium feel or prevent glare.
