ASTMG65

ASTM G65 refers to the Standard Test Method for Abrasion Resistance of Materials by the Rotating Wheel Abraser, an ASTM International standard used to evaluate how well a material resists wear under abrasive action. The method provides a controlled laboratory procedure to compare the relative abrasion resistance of a wide range of materials, including coatings, plastics, elastomers, textiles, composites, and other solid surfaces.

The standard specifies the test apparatus, typically a rotating wheel abrader, an abrasive media, and mounting hardware for test specimens. It also outlines the means to apply a controlled load and wheel speed, as well as the selection of abrasive types and test durations or revolutions. Specimen preparation and conditioning procedures are described to ensure consistency between tests.

During testing, the specimen is subjected to abrasion by the rotating wheel under defined conditions for a set number of revolutions or cycles. Post-test measurements, such as mass loss, thickness loss, or wear scar depth, are recorded. Results are commonly expressed as weight or volume loss per revolutions or cycles, and may be used for a comparative rating relative to reference materials.

The standard provides guidance on data interpretation, reporting formats, and potential sources of error. It is widely used in quality control, product development, and research to assess the durability of coatings, polymers, textiles, composites, and bonded assemblies under abrasive conditions. As with all ASTM standards, revisions may update procedures and criteria, so practitioners should consult the current edition for precise requirements.
