The work of preparing Inter

14、national 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 represented on that committee. International organizations, governmental and non-governmental, in liaison wit

15、h 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 drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technica

16、l 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 International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to

27、ISO 2005 All rights reservedIntroduction Thermal-sprayed metallic coatings are produced by heating the coating metal to its molten stage and projecting it in a stream of gas onto the prepared surface to be coated. It is essential that the purchaser specifies the coating metal or alloy and the thickn

28、ess of the coating required: merely to ask for thermal metal spraying to be carried out in accordance with this standard, without this information, is insufficient. It is essential that the design of the article is such that it may be coated properly. SANS 2063:2008This s tandard may only be used an

30、urface to be protected. This standard deals with characteristic properties and gives test methods for coatings obtained by the spraying of zinc and aluminium and their alloys for the general purpose of corrosion protection. It gives firstly the definition, classification and symbols for these coatin

31、gs in relation to their thickness. It then deals with the preparation of surfaces, application of coatings and their characteristic properties: namely, thickness, appearance and adhesion. Finally it gives test methods for checking these properties. For other metals some of the provisions are valid a

32、nd can be adopted by agreement between the interested parties. 2 Normative references The following referenced documents are indispensable for the application of this document.
