UNE EN ISO 8503-5:2017
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.
