20、09 All rights reservedForeword ISO (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

21、 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 the work. ISO collaborates closely with the International Electrotechnical Commissio

22、n (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical co

23、mmittees 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 document may be the subject of patent rights. ISO shall no

24、t be held responsible for identifying any or all such patent rights. ISO 1456 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings, Subcommittee SC 3, Electrodeposited coatings and related finishes. This fourth edition cancels and replaces the third edition (ISO 1456

25、:2003), which has been technically and editorially revised. This edition also cancels and replaces ISO 1458:2002. BS EN ISO 1456:2009ISO 1456:2009(E) ISO 2009 All rights reserved vIntroduction This International Standard is a revised version of ISO 1456:2003: Metallic coatings Electrodeposited coati

26、ngs of nickel plus chromium and of copper plus nickel plus chromium incorporating ISO 1458:2002: Metallic coatings Electrodeposited coatings of nickel. Decorative, electrodeposited nickel coatings, with and without copper undercoats and without chromium top-coats, are suitable for applications in wh

27、ich tarnishing could be prevented by avoiding rubbing or handling in service or by the use of topcoats 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. Decorative, electrod

28、eposited nickel plus chromium and copper plus nickel plus chromium coatings are applied to manufactured articles to enhance their appearance and corrosion resistance. Corrosion resistance depends on the type and thickness of the coatings. In general, multilayer nickel coatings provide better corrosi

29、on resistance than single-layer nickel coatings of equal thickness, and micro-discontinuous chromium coatings provide better protection than conventional chromium.

30、 coatings Electrodeposited coatings of nickel, nickel plus chromium, copper plus nickel and of copper plus nickel plus chromium WARNING This International Standard may not be compliant with some countries health and safety legislations and calls for the use of substances and/or procedures that may b

31、e injurious to health if adequate safety measures are not taken. This International Standard does not address any health hazards, safety or environmental matters and legislations associated with its use. It is the responsibility of the user of this International Standard to establish appropriate hea

32、lth, safety and environmentally acceptable practices and take suitable actions to comply with any national and international regulations. Compliance with this International Standard does not in itself confer immunity from legal obligations. 1 Scope This International Standard specifies requirements

33、for decorative nickel, nickel plus chromium, copper plus nickel and copper plus nickel plus chromium coatings that are applied to iron, steel, zinc alloys, copper and copper alloys, and to aluminium and aluminium alloys, to provide an attractive appearance and enhanced corrosion resistance. Coating

34、designations are specified that differ in thickness and type, and guidance is given on selecting the coating designation appropriate for the service conditions to which the coated product will be exposed. This International Standard does not specify the surface condition required by the basis metal

35、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 decorative, electroplated copper plus nickel plus chromium coatings on plastic materials are specified in ISO 4525. ISO 4526

36、and ISO 6158 specify requirements for coatings of nickel and chromium, respectively, for engineering purposes. 2 Normative references The following referenced documents are indispensable for the application of this document.
