Anotace obsahu normy

This International Standard specifies requirements for non-electrolytically applied zinc flake coatings for steel fasteners. It applies to coatings:
- with or without hexavalent chromium;
- with or without top coat;
- with or without lubricant (integral lubricant and/or subsequently added lubricant).
National regulations for the restriction or prohibition of certain chemical elements should be taken into account in the countries or regions concerned. It applies to bolts, screws, studs and nuts with ISO metric thread, to fasteners with non-ISO metric thread, and to non-threaded fasteners such as washers, pins, clips, etc.
NOTE - Coatings in accordance with this International Standard are especially used for high strength fasteners (>= 1 000 MPa) to avoid risk of internal hydrogen embrittlement (see 4.4).
Information for design and assembly of coated fasteners is given in Annex A.
This International Standard does not specify requirements for such fastener properties as weldability or paintability. It does not apply to mechanically applied zinc coatings.
