This tutorial explains how to determine the degree of rusting on painted steel (or iron) surfaces. The 27 reference color photographs and accompanying black and white images show the maximum percentage of rusting allowed for each rust grade 1-9. This standard uses a zero-to-ten scale to determine the degree of rusting on painted steel surfaces based on the proportion of visible rust present.
