Overview
This part of DIN EN ISO 8503 describes the stylus instrument and the method for calibrating ISO surface profile comparators conforming to the requirements of ISO 8503-1. This standard is also applicable to the determination of the mean of the mean maximum peak-to-valley height (by stylus) within the range 20 µm to 200 µm, of essentially planar blast-cleaned steel (components). The determination can be carried out on a representative section of the blast-cleaned substrate or, when this is not possible, on a replica of the substrate. Where appropriate, this method can be used to assess the roughness profile of other abrasive blast-cleaned substrates. An alternative method is described in ISO 8503-3. The International Standard forming the basis of this standard has been prepared by Technical Committee ISO/TC 35 "Paints and varnishes" in collaboration with Technical Committee CEN/TC 139 "Paints and varnishes", the secretariat of which is held by DIN. The committee responsible for this standard is NA 002-00-10-04 UA "Oberflächenvorbereitung und -prüfung" ("Surface preparation and testing") at DIN.
