This document describes methods for hand-tool and power-tool cleaning of steel substrates beforeapplication of paints and related products. It is applicable both to new steelwork and to steel surfacesthat have been coated previously and that show areas of breakdown requiring maintenance painting.Itdescribes the equipment to be used and the procedures to be followed.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references,only the edition cited applies.Forundated references, the latest edition of the referenced document (including any amendments) applies.ISO 8501-1, Preparation of steel substrates before application of paints and related products — Visualassessment of surface cleanliness—Part 1: Rust grades and preparation grades of uncoated steel substratesand of steel substrates after overall removal of previous coatings.
ISO 8501-2,Preparation of steel substrates before application of paints and related products —Visualassessment of surface cleanliness —Part 2: Preparation grades of previously coated steel substrates afterlocalized removal of previous coatings.For the purposes of this document, the following terms and definitions apply.method of preparing steel substrates by the use of hand tools, without power assistance
Note 1 to entry:Chipping hammers, hand scrapers, hand wire brushes, abrasive papers and plastic fleece withembedded abrasive are generally used.Hand-tool cleaning is sometimes carried out initially in order to removerelatively loose contaminants prior to the use of power tools.
method of preparing steel substrates by the use of power-assisted hand tools, but excluding 1 to entry: Rotary de-scalers, rotary wire brushes, rotary impact tools, sanding machines, sanding discs,rotary abrasive-coated paper wheels (flap wheels), abrasive grinders, plastic fleece with embedded abrasive,chipping hammers and needle guns, driven by electric or pneumatic power, or attached to a remote controlled orrobotic equipment,are examples of equipment generally used.method for removing visible oil, grease, soil or machining lubricants, and other soluble contaminants,from steel surfacesNote 1 to entry: For more details and cleaning methods see lS0 12944-4:2017, surface on which matter deleterious to the performance of a protective coating system is present.Note 1 to entry:Typical contaminants include slag,rust, laminated rust scale, mill scale, oil, grease, welding fluxand weld spatter, soluble iron corrosion products and other soluble salts, including chlorides and sulphates.surface from which the contamination has been removed to the specified or agreed level of surfacecleanlinessNote 1 to entry: Full details are given in IS0 8501-1 and ISo 8501-2.ISO 8504 pdf download.
