Vorbereitung von Stahloberflächen vor dem Auftragen von Beschichtungsstoffen - Rauheitskenngrößen von gestrahlten Stahloberflächen - Teil 5: Abdruckverfahren zum Bestimmen der Rauheit (ISO 8503-5:2017); Deutsche Fassung EN ISO 8503-5:2017
Overview
This part of ISO 8503 describes a field method for measuring the surface profile produced by any of the abrasive blast-cleaning procedures given in ISO 8504-2. The method uses replica tape and a suitable gauge for measuring, on site, the roughness of a surface before the application of paint or another protective coating. The method is applicable within the range of profile heights cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit measurement of average peak-to-valley profiles of 20 μm to 115 μm. The method is valid for surfaces that have been cleaned with abrasives. This document (EN ISO 8503-5:2017) 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 (Germany). The responsible German/national committee is Working Committee NA 002-00-10-04 UA "Oberflächenvorbereitung und -prüfung" ("Surface preparation and testing") at DIN Standards Committee Coatings and Coating Materials (NAB).
