This part of ISO 8501 specifies a series of rust grades and preparationgrades of steel surfaces (see Clauses 2 and 3, respectively). The variousgrades are defined by written descriptions together with photographs thatare representative examples within the tolerance for each grade asdescribed in words.It is applicable to hot-rolled steel surfaces prepared for painting by methodssuch 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 thicknessto withstand any deformation caused by the impact of the abrasive or theeffects of power tool cleaning.This part of ISO 8501 is applicable also to steel substrates that showresidues of firmly adhering paint and other foreign matter (see Note 2 to 3.1)in addition to residual mill scale.
