(h) Treatment with acid solutions (non-immersion) . . . . . . . . . . . . AS 1627.10
The Standard also makes reference to AS 1627.9, which gives pictorial guidance on surface finishes of steel after various treatments. The AS 1627 series of Standards apply primarily to surfaces intended to be painted, powder coated, metal sprayed or hot dipped in molten metal. For requirements for surface preparation prior to the application of electroplated coatings refer to ASTM B 183, ASTM B 242, ASTM B 252, ASTM B 253 and ASTM B 254.
NOTE: Before any of these surface preparation methods are applied to a metal surface, it is important that, where necessary, prior dressing be carried out to remove any gross defects present on the surface (see Clause 3.2).
