7、rd 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 subject for which a technic
8、al 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 Commission (IEC) on all matters of el
9、ectrotechnical 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 committees are circulated to t
10、he 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 not be held responsible for id

20、urface to be coated. It is essential that the purchaser specifies the coating metal or alloy and the thickness 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 des
21、ign of the article is such that it may be coated properly. -,-,- ISO 2063:2005(E) ISO 2005 All rights reserved 1 1 Scope This standard applies to thermal-sprayed metallic coatings for the protection of iron and steel against corrosion by applying zinc or aluminium or their alloys to uncoated surface
22、 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 coatings in
23、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 and can
24、 be adopted by agreement between the interested parties. 2 Normative references The following referenced documents are indispensable for the application of this document.
