36、alent chromium) for all parties involved in the fastener field, i.e. chemical suppliers, coaters, fastener manufacturers, distributors and end users. It covers all types of fasteners, i.e. fasteners with ISO metric thread, fasteners with non-ISO metric thread (including thread forming, ASME inch 60

37、screw thread, etc.) and non-threaded fasteners (including washers, pins, clips, etc.). It also provides basic advice for the design and use of coated fasteners in assembly.4DIN EN ISO 10683:2014-10 EN ISO 10683:2014 (E) 1 ScopeThis International Standard specifies requirements for non-electrolytical

38、ly 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 el

39、ements 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 S

40、tandard 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 weldabi

41、lity or paintability. It does not apply to mechanically applied zinc coatings.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

45、 purposes of this document, the terms and definitions given in ISO 1891-2 apply.4 General characteristics of the coating4.1 Zinc flake coating systemsZinc flake coating systems are produced by applying a zinc flake dispersion to the surface of a steel fastener, usually with the addition of aluminium

46、 flakes, in a suitable medium. Under the influence of heat (curing), a bonding amongst flakes and also between flakes and substrate is generated, thus forming an inorganic surface coating sufficiently electrically conducting to ensure cathodic protection. The coating may or may not contain hexavalen

47、t chromium, Cr(VI).Special techniques may be necessary to avoid excessive or insufficient coating thickness.Special techniques may be necessary to prevent lightweight and/or flat fasteners from sticking together (e.g. washers, clips, fasteners with captive washer, flanged nuts).An additional top coa

48、t can be applied to increase corrosion resistance and/or to achieve specific properties (e.g. torque/tension properties, chemical resistance, aspect, colour, electrical insulation/conductivity see A.2).4.2 Composition of the systemsThere are four basic zinc flake coating systems as shown in Figure 1

49、.Key1 only base coat2 base coat + lubricant3 base coat + top coat4 base coat + top coat + lubricantFigure 1 Basic zinc flake coating systemsBase coat and top coat can be with integral lubricant, see detailed possible combinations in A.1.2.4.3 Mechanical and physical properties and curingThe coating process shall not adversely influence the mechanical and physical properties of the fasteners.NOTE Distributors
