适用范围：1 This part of ISO 8503 specifies the focusing microscope and describes the procedure for calibrating ISO surface profile comparators complying with the requirements of ISO 8503-1.2 This part of ISO 8503 is also applicable_to the determina-tion of the surface profile, within the range hy = 20 to 200 nm, of essentially planar blast-cleaned steel. The determination may be carried out on a representative section of the blast-cleaned substrate or, if direct observation of the surface is not feasible, on a replica of the surface (see annex E).NOTE — Where appropriate, this procedure may be used for assessing the roughness profile of other abrasive blast-cleaned substrates.An alternative procedure is described in ISO 8503-4.
