This is the most direct and reliable source. The ASTM store lists the standard with the designation D0523-25.

Q: What is the purpose of ASTM D523? A: The purpose of ASTM D523 is to provide a standard test method for measuring the specular gloss of surfaces. astm d523 pdf new

The standard starting point for all finishes. It is used to categorize a surface before more specialized testing.

The ASTM D523 standard is the definitive global method for measuring specular gloss on nonmetallic materials. With the release of , it is crucial for all professionals in coatings, plastics, and manufacturing to ensure they are referencing the most up-to-date procedures.

Requirements for the glossmeter (light source, receiver, and receptor). The newest iteration of this standard is ,

No. The calibration procedure (frequency, standards, environmental conditions) is detailed only in the full new PDF. Guessing voids your ISO compliance.

Used for surfaces that measure above 70 Gloss Units (GU) at the 60° angle. This geometry provides better resolution for very shiny coatings.

Nonmetallic specimens (e.g., paints, plastics, coatings). If you tell me what type of material

The ASTM D523 standard has various applications in different industries, including:

There is no fixed schedule. ASTM standards are reviewed periodically and can be revised, reapproved without change, or withdrawn. The previous version, D523-14, was current from 2014 until the release of D523-25 in 2025.

Using the correct version of a standard is paramount for legal, contractual, and quality reasons. Industry regulations, quality management systems (e.g., ISO 9001), and product certifications often mandate the use of current standards. Furthermore, when testing is performed for a client, the test report must cite the specific version of the standard used. Citing an older version like ASTM D523-14 when a newer version exists could lead to non-compliance. For these reasons, the ASTM D523 PDF representing the 2025 version is an essential resource for any testing laboratory, quality control department, or R&D facility involved in appearance measurement.

These are authorized resellers. They often bundle ASTM D523 with other gloss-related standards (e.g., ISO 2813, which is technically similar but not identical).

The new standard requires:
