This standard specifies visual means for detecting rust grades and preparation grade of steel surface before painting. It is applicable to hot-strip surface that has been de-rusting through blast rust cleaning, manual and power tool cleaning and flame cleaning. The standard may also service as reference for rust grades assessment of cold rolled steels. This standard is equivalent to International Standard ISO 8501-1: 1988 "Steel Pretreatment before Application of Painting and Relevant Product -- Visual Assessment of Surface Clearness -- Part 1: Rust Grade of Un-Cleaned Steel And Preparation Grade of Steel That Has Been Completely Cleaned".
