Paints and Varnishes - Corrosion Protection of Steel Structures by Protective Paint Systems - Part 4: Types of Surface and Surface Preparation - Corrected 1998
 N EN ISO 12944-4

Annotation

This part of IS0 12944 deals with 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-dipgalvanized surfaces;

- zinc-electroplated surfaces;

- sherardized surfaces;

- surfaces painted with prefabrication primer;

- other painted surfaces.

This part of IS0 12944 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 part of IS0 12944.
