23、 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 established has the right to be repre
24、sented 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 standardization. International Standards are
25、 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 committees are circulated to the member bodies for voting. Publication as an Internationa

28、8 All rights reserved vIntroduction Electrodeposits of cadmium are used to protect iron and steel from corrosion. Cadmium is anodic and corrodes sacrificially, thus protecting ferrous basis metals even when exposed through pores or pits in the cadmium. Electrodeposited cadmium coatings have traditio
29、nally been applied to iron or steel from alkaline cyanide solutions, but in recent years, environmental concerns and regulations have led to increased use of acid sulphate, neutral chloride and acid fluoborate cadmium solutions. Because the appearance and serviceability of electroplated cadmium coat
30、ings are influenced by the surface condition of the basis metal, agreement should be reached between the interested parties that the surface of the basis metal is satisfactory for electroplating. Cadmium is highly toxic and health, safety and environmental concerns are eliminating its non-essential
31、uses. There remain, nevertheless, critical applications, often aerospace-related, where the unique properties of electrodeposited cadmium coatings, for example, their corrosion resistance, intrinsic lubricity, ductility, electrical conductivity and low contact resistance, make continued use of cadmi
32、um coatings necessary. The corrosion resistance of electroplated cadmium coatings and their tendency to tarnish when handled can be improved by applying chromate conversion and other supplementary coatings. Chemical conversion coatings that do not contain hexavalent chromium are commercially availab
33、le and their use is becoming more and more popular. The appearance of these substitutes may be different from those produced with hexavalent chromium. Other conversion coatings that are chromium-free are also available. Substitutes are required to satisfy the corrosion requirements given in this Int

35、 During heat treatment, all precautions should be taken to ensure that no person is exposed to it. Attention is also drawn to the danger arising from welding, soldering or heating and other operations, in which the possibility that cadmium will be vaporised exists. Because of its toxicity, cadmium s
36、hould not be employed as a coating for any article that will come in contact with food or beverages or containers in contact with these items or any household goods. WARNING This International Standard may not be compliant with some countries health, safety and environmental legislations and calls f
37、or the use of substances and/or procedures that may be 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 producers,
38、purchasers and/or user of this International Standard to establish appropriate health, safety and environmentally acceptable practices and take appropriate actions to comply with any national, regional and/or international rules and regulations. Compliance with this International Standard does not,
39、of itself, confer immunity from legal obligations. 1 Scope This International Standard specifies the requirements of electroplated coatings of cadmium with supplementary treatments on iron and steel. It includes information that is to be supplied by the purchaser to the electroplater, and describes
40、coating requirements, including those for heat treatment before and after electroplating. It is not applicable to coatings applied to sheet, strip or wire in the non-fabricated form, to close-coiled springs, or for purposes other than protective, intrinsic lubricity, ductility, electrical conductivi
41、ty and low contact resistance use. This International Standard does not specify requirements for the surface condition of the basis metal prior to electrodeposition with cadmium. The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including cl
42、ass or fit. BS EN ISO 2082:2008ISO 2082:2008(E) 2 ISO 2008 All rights reserved2 Normative references The following referenced documents are indispensable for the application of this document.
