Preparation of steel substrates before application of paints and related products. Visual assessment of surface cleanliness - Preparation grades of welds, edges and other areas with surface imperfections Ingestion-build-201039 This part of ISO 181721 Scope This part of ISO 8501 describes preparation grades of welds, edges and other areas, on steel surfaces with imperfections. Such imperfections can become visible before and or after an abrasive blast cleaning process. The preparation grades given in this part of ISO 8501 are to make steel surfaces with imperfections, including welded and fabricated surfaces, suitable for the application of paints and related products.
