11、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 which a technical committee has been esta
12、blished 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 all matters of electrotechnical standardiza
13、tion. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75
14、% of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 1458 was prepared by
15、Technical Committee ISO/TC 107, Metallic and other inorganic coatings, Subcommittee SC 3, Electrodeposited coatings and related finishes. This third edition cancels and replaces the second edition (ISO 1458:1988), which has been technically revised. Annexes B, C and D form a normative part of this I
16、nternational Standard. Annex A is for information only.

17、HS -,-,- ISO 1458:2002(E) ISO 2002 All rights reserved v Introduction Decorative, electrodeposited nickel coatings with and without copper undercoats and without chromium top-coats are suitable for applications in which tarnishing is prevented by rubbing or handling in service or by the use of topco
18、ats other than chromium. They are also suitable for those applications where tarnishing is of no importance. Corrosion resistance depends on the type and thickness of the coatings. In general, multilayer nickel coatings provide better protection than single-layer nickel coatings of equal thickness.

21、odeposited coatings of nickel 1Scope This International Standard specifies requirements for nickel electrodeposited coatings that are applied to iron and steel, to zinc alloys, to copper and copper alloys, and to aluminium and aluminium alloys to provide an attractive appearance and corrosion resist
22、ance. In addition, it specifies requirements for copper plus nickel coatings applied to iron and steel, and to zinc alloys. Coating designations that differ in thickness and type are specified and guidance is given in selecting the coating appropriate to the service conditions to which the coated pr
23、oduct will be exposed. This International Standard does not specify the surface condition required by the basis metal prior to the coating process, and is not applicable to coatings on sheet strip or wire in the non-fabricated form nor to threaded fasteners or coil springs. Requirements for nickel p
24、lus chromium and copper plus nickel plus chromium coatings for metallic substrates are given in ISO 1456. Requirements for similar coatings for plastic materials are given in ISO 4525. ISO 4526 and ISO 6158 specify requirements for coatings of nickel and chromium, respectively, for engineering purpo
25、ses. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to ag
