适用范围：This part of ISO 8501 specifies a series of rust grades and preparation grades of steel surfaces (see Clauses 2 and 3, respectively). The various grades are defined by written descriptions together with photographs that are representative examples within the tolerance for each grade as described in words.It is applicable to hot-rolled steel surfaces prepared for painting by methods such as blast-cleaning, hand and power tool cleaning and flame cleaning, although these methods rarely lead to comparable results. Essentially, these methods are intended for hot-rolled steel, but blast-cleaning methods,in particular, could also be used on cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive or the effects of power tool cleaning.This part of ISO 8501 is applicable also to steel substrates that show residues of firmly adhering paint and other foreign matter (see Note 2 to 3.1) in addition to residual mill scale. NOTE 1 The preparation grades of previously painted steel surfaces after only localized removal of paint coatings form the subject of ISO 8501-2
