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 with embedded abrasive are generally used. Hand-tool cleaning is sometimes carried out initially in order to remove relatively loose contaminants prior to the use of power tools.
method of preparing steel substrates by the use of power-assisted hand tools, but excluding blast-cleaning
Note 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 or robotic equipment, are examples of equipment generally used.ISO 8504-3 pdf download.
