GB/T 12336-1990 "Standard Method for Statistical Analysis of Corrosion Data" was proposed by the Ministry of Machinery and Electronics Industry of the People's Republic of China and provides a general statistical analysis method for corrosion test data. The standard describes the processing and analysis procedures of corrosion data in detail, aiming to help users accurately evaluate the corrosion performance of materials through systematic statistical methods, and provide a scientific basis for corrosion research and material selection.
