GB/T 19816.3-2005
ActivePreparation of steel substrates before application of paints and related products-Test methods for metallic blast-cleaning abrasives-Part 3:Determination of hardness
涂覆涂料前钢材表面处理 喷射清理用金属磨料的试验方法 第3部分:硬度的测定
Application Summary AI generated
This standard specifies the test method for determining the hardness of metallic blast-cleaning abrasives used in surface preparation. It is applied in the manufacturing and industrial coating sectors, specifically for quality control of abrasives like steel shot or grit before they are used to clean steel substrates. The hardness measurement ensures consistent abrasive performance and surface profile during paint or coating application.
