Scope

WARNING: Abrasives, materials, and equipment 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 18838 specifies the technical requirements for 12 grades of low-carbon cast steel shot abrasives for blast cleaning, including hardness, density, defect and structural requirements, and chemical composition. The requirements specified in this part of GB/T 18838 apply only to unused abrasives, not to used abrasives. See the various parts of GB/T 19816 for the test methods of metal abrasives for blast cleaning. Low carbon cast steel shot is a recyclable and reusable abrasive for both stationary and on-site blasting equipment.
