Application Summary AI generated

This standard specifies a test method for determining the apparent density of metallic blast-cleaning abrasives used in surface preparation. It is applied in manufacturing and industrial coating contexts, specifically for steel substrates that require cleaning and profiling before the application of paints or protective coatings. The method ensures quality control of abrasives like steel shot or grit, which are critical for achieving consistent surface roughness in shipbuilding, bridge construction, and heavy machinery.
