scope:

This European Standard describes the characteristics of and specifies requirements for non-electrolytically applied coatings, composed mainly of zinc flakes, for the protection against corrosion of steel components, excluding threaded fasteners for which another specification exists (see prEN ISO 10683). It specifies minimum corrosion resistance to the neutral salt spray test in accordance with ISO 9227 when applied to steel components. The coatings can be supplied with integral lubricant if specified. The application processes used for zinc flake coatings do not induce hydrogen embrittlement. For this reason, these coatings are specifically recommended for the protection of high strength steel components ( Rm ³ 1 000 MPa). The time and temperature used for the curing of the coating can influence the mechanical characteristics of certain components due to their metallurgical condition.
