Paints and varnishes. Corrosion protection of steel structures by protective paint systems -- Types of surface and surface preparation
This document covers the following types of surfaces of steel structures consisting of carbon or low-alloy steel, and their preparation:
uncoated surfaces;
surfaces thermally sprayed with zinc, aluminium or their alloys;
hot-dip-galvanized surfaces;
zinc-electroplated surfaces;
sherardized surfaces;
surfaces painted with prefabrication primer;
other painted surfaces.
This document defines a number of surface preparation grades but does not specify any requirements for the condition of the substrate prior to surface preparation.
Highly polished surfaces and work-hardened surfaces are not covered by this document.
