GB/T 4 2924.1 - 2023 begins a series of standards for the determination of corrosion of plastics combustion flow, focusing on general terms and applications. It clearly defines relevant professional terms, such as combustion flow, corrosion, etc., to make industry communication clearer. It expounds the importance of measuring the corrosion of plastics combustion flow, and introduces the application of this measurement in different scenarios, such as electronic equipment and building materials. It also sorts out the scope of application of the standard, explaining the types of plastics and the limitations of test conditions. Lay the foundation for subsequent specific test method standards, and help industries understand and apply the relevant knowledge of corrosion measurement of plastics combustion flow.
