"GB/T 19816.2-2005 Test method for metal abrasives for jet cleaning of steel surface preparation before coating Coatings, Part 2: Determination of particle size distribution" specifies the screening method for measuring the size distribution of metal abrasives for jet cleaning. The standard is suitable for evaluating the particle size distribution of metal abrasives, and determining the particle size range and uniformity of abrasives through screening tests to ensure that they can effectively remove impurities on the surface of steel during jet cleaning. The standard is centralized by China Shipbuilding Industry Group company. It was issued on June 10, 2005 and implemented on November 1, 2005. It provides an important basis for the quality control of metal abrasives for jet cleaning.
