Scope

WARNING: Equipment, materials, and abrasives used in surface preparation can be hazardous if not handled with care. Many countries have regulations for materials and abrasives that are considered hazardous during or after use (waste management), such as free silicon, carcinogens or toxic substances. Therefore, these regulations should be followed. It is important to ensure that proper guidance is given and that all required precautions are followed. This part of GB/T 17850 specifies the particle size range, apparent density, Mohs hardness, water content, conductivity of water leaching solution, water-soluble chloride content and particle adsorbate content of steel slag special abrasive abrasives for blast cleaning. The requirements specified in this standard apply only to unused abrasives and not to used abrasives. See GB/T 17849 for the test methods of non-metallic abrasives for blast cleaning.
