ISO 8501 Book Corrosion Protection of Steel Structures by Painting
ISO 8501 -1 Book
In 2007 updated version of the standard measure for the visual evaluation of rust and purity levels of non-coated steel. Also known as the “Swedish steel blasting grades” SS 05 59 00 (Sa). Contains high-quality colour photographs for estimating the rust levels and purity levels after cleaning manually or by machine (also with blasting). Target audience: Blasting and painting companies and their clients, paint technicians, advice bureaux and industrial coating businesses.
Purity levels of painted steel surfaces from which the paint layer has been weathered in places. Indispensable when repairing damage to corrosion-resistant paint systems and in the conservation or, for example, welding joints after construction.
Describes preparation grades of welds, cut 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 are to make steel surfaces with imperfections, including welded and fabricated surfaces, suitable for the application of paints and related products.
ISO 8501 -4
Specifies a series of preparation grades for steel surfaces after removal/partial removal of water-soluble contaminants, rust, previous paint coatings and foreign matter by high-pressure water jetting. The writer defined, and descriptions together with photographs of various grades. That are representative examples within the tolerances for each grade as described in words. In addition, this part of ISO 8501 specifies both initial surface conditions and after-cleaning flash rust grades, also defined by written descriptions together with representative photographic examples.
