TQCSHEEN LD3020 ISO 8501 CORROSION PROTECTION OF STEEL STRUCTURES BY PAINTING
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.
