1.1 The visual surface preparation standards consist of a series of color prints available as separatepublications. Three different sets of photographs are described in this standard, designated as Method A(ISO/Swedish Standard) and Method B and C (SSPC Standards). The three methods differ in the depictionof the initial surface, in the definition and depiction of the cleaning conditions, and in the number of cleaningmethods included. Because of these differences, the specifier should state whether Method A, Method B, orC should be used.
1.2 The colored visual surface preparation standards represent different conditions of hot rolled steel beforeand after surface preparation. Prior to cleaning, there are four rust grades, A to D, that cover the range fromintact mill scale to 100% rusted and pitted steel. The standards then depict the appearance of the four gradesafter cleaning by one or more methods (for example, blast cleaning) to various degrees of thoroughness. Inaddition, Method C includes three painted conditions that contain various degrees of rusting. The Standarddepicts these conditions after various grades of hand and power tool cleaning.
