GB/T 43605-2023Drawing method of atmospheric corrosion map (English PDF)

1 Scope

This document describes the method for drawing regional atmospheric corrosion maps based on atmospheric environment corrosion tests and data, including general provisions, drawing flow

Processing, drawing data preparation, geospatial interpolation model construction, data source blank area assignment, drawing, drawing output, and preparation of drawing instructions:

This document is suitable for using the corrosion rate of metal materials to evaluate the atmospheric corrosiveness and then drawing atmospheric corrosion maps:

Note: The metal materials mentioned in this document refer to metals, alloys and metal-based covering layers:
