In ≤ 0.1mmg/cm²/dei: Kin negearre wurde of hat gjin korrosje, oanrikkemandearre foar gebrûk.
B = 0.1~0.3mmg/cm²/dei: Lichte of tige lytse korrosje, brûk mei foarsichtigens.
C ≥ 0,3 mmg/cm²/dei: Signifikante korrosje, net oanrikkemandearre foar gebrûk.
-- : Yntinsive korrosje, foar safier't mjitting net mooglik is.
