Overview
This part of DIN EN ISO 8503 specifies requirements for the optical microscope and describes the method for calibrating ISO surface profile comparators conforming to the requirements of ISO 8503-1. The standard is also applicable to the determination of the mean maximum peak-to-valley height (by microscopy) within the range of 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 surface. Where appropriate, this method can be used for assessing the roughness profile of other abrasive blast cleaned substrates. An alternative method is described in ISO 8503-4. 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.
