The work of preparing International Standards is no
13、rmally carried out through ISO technical committees. Each member body interested in a subject for 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
14、 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the tech
15、nical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % 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 paten
16、t rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 1456 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings, Subcommittee SC 3, Electrodeposited coatings and related finishes. This third edition canc
17、els and replaces the second edition (ISO 1456:1988), which has been editorially and technically revised. Annexes B to E form a normative part of this International Standard. Annex A is for information only. BS ISO 1456:2003 iv Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 11:39:50 GMT+00:00

Corrosion resistan

In general, multilayer nickel coatings provide better corrosion resistance than single-layer nickel coatings of equal thickness, and microdiscontinuous chromium coatings provide better protection than conventional chromium.

Coating designations are specified that differ in thickness and type, and guidance is given in selecting the coating designation appropriate to the service conditions to which the coated pro

This International Standard does not specify the surface condition required by the base 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 decorativ

Similar coatings, except for the absence of a top-coat of chromium, are specified in ISO 1458. ISO 4526 and ISO 6158 specify requirements for coatings of nickel and chromium, respectively, for
