A ≤ 0.1 mmg/sm²/kun: E'tiborsiz qoldirilishi mumkin yoki korroziyaga ega emas, foydalanish tavsiya etiladi.
B = 0,1~0,3 mmg/sm²/kun: Yengil yoki juda kichik korroziya, ehtiyotkorlik bilan foydalaning.
C ≥ 0.3 mmg/sm²/kun: Sezilarli darajada korroziyaga uchragan, foydalanish tavsiya etilmaydi.
--: O'lchashning iloji bo'lmagan darajada kuchli korroziya.
