GB/T 39637-2020 Corrosion of metals and alloys—Classification of soil corrosivity

Scope: This standard specifies the classification of soil environmental corrosivity. The classification of soil environmental corrosivity based on the corrosion rate of metal standard samples and the assessment of corrosion based on soil environmental data. This standard applies to the classification and assessment of the corrosivity of general soil environments. This standard does not apply to the classification and assessment of the corrosivity of special soil environments, such as soil environments with obvious AC and DC interference, soil environments with obvious regional heterogeneity and local soil environments polluted by other chemical substances.
