Quantifying Levels of Corrosion based on Visual Inspection 1

[CWEngineer]

I am looking for a reference that gives guidance for describing corrosion based on visual inspections. For example, I am trying to figure out when you would quantify corrosion as being light, moderate, very corroded, severe, etc.

Thanks

ASTM International has some standards in this area:

ASTM D610 Standard Practice for Evaluating Degree of Rusting on Painted Steel Surfaces seems most appropriate.
