21、683:2014(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for
22、 which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on a

33、The revision of ISO 10683:2000 was made in order to define the relevant requirements on zinc flake coated fasteners (coating systems with and without hexavalent chromium) for all parties involved in the fastener field, i.e. chemical suppliers, coaters, fastener manufacturers, distributors and end us
34、ers. 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 screw thread, etc.) and non-threaded fasteners (including washers, pins, clips, etc.). It also provides basic advice for the design and use of co
35、ated fasteners in assembly.vi ISO 2014 All rights reservedBS EN ISO 10683:2014INTERNATIONAL STANDARD ISO 10683:2014(E)Fasteners Non-electrolytically applied zinc flake coatings1 ScopeThis International Standard specifies requirements for non-electrolytically applied zinc flake coatings for steel fas
36、teners. 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 c
37、ountries 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 strengt
38、h 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 m

43、ment, 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 flakes, in a suitable
44、 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 hexavalent chromium, Cr(VI).Spe
45、cial 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 coat can be applied to in
46、crease 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.Key1 only base coat2
47、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 adve
48、rsely influence the mechanical and physical properties of the fasteners.NOTE Distributors who coat non-coated fasteners are considered as alteration coating distributors in accordance with ISO 16426.9Depending on the zinc flake coating system, the curing temperatures can be up to 320 C. The curing t
49、emperature shall not be above the tempering temperature of quenched and tempered fasteners.2 ISO 2014 All rights reservedBS EN ISO 10683:2014ISO 10683:2014(E)WARNING The curing process (especially with higher temperature and/or longer duration) may affect the fatigue limit of fasteners with thread rolled after heat treatment. See also A.1.3 for other possible effects of curing.4.4 Avoidance of internal hydrogen embrittlementA characteristic of zinc flake coating systems is that hydrogen is not generated
