ISO 8503-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 12, Preparation of steel substrates before application of paints and related products.
ISO 8503-1:2012 specifies the requirements for ISO surface profile comparators, which are intended for visual and tactile comparison of steel substrates which have been blast-cleaned with either shot abrasives or grit abrasives.
ISO 8503-1 standard for preparing steel surfaces before painting. Covers roughness, blast cleaning, and surface profile comparators.
NOTE — In the absonce of agreement, calibration by the method described in ISO 85033 is the referee procedure If at any time the comparator, when calibrated using the stylus ‘method (ISO 8503-4) or the microscope method {ISO 8803-3), does not comply with the specified limits given in table 1, it shall be discarded.
ISO 8503-1 is an ISO standard procedure that will help you to assess abrasive, blast-cleaned surfaces of steel substrates before applying protective paint.
BS EN ISO 8503 - Preparation of steel substrates before application of ...
International Standards ISO 8501 (all parts), ISO 8502 (all parts) and ISO 8503 (all parts) have been prepared to provide methods of assessing these factors, while ISO 8504 (all parts) provides guidance on the preparation methods which are available for cleaning steel substrates, indicating the capabilities of each in attaining specified levels ...
This part of ISO 8503 also includes definitions of the terms used in the ISO 8503 series and requirements for the care of ISO surface profile comparators. NOTE 1 ISO surface profile comparators are used for assessing, on site, the roughness of surfaces before the application of paints and related products or other protective treatments.
