24、zation) 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 b

25、e 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 electrotechnical standardization. International Standa

26、rds 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 the member bodies for voting. Publication as an Inter

27、national 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 identifying any or all such patent rights.

This third edition cancels and replaces the second edition (ISO 1461:1999), which has been technically revised. This revision reflects the experience gained in

29、 the use of ISO 1461 and includes a simplification of procedures and presentation. Significant changes to the text include the following: g127 further refining of the scope of application of the standard to exclude woven or welded mesh products that are continuously galvanized; g127 adding a definit

33、elt (containing not more than 2 % of other metals). It does not apply to the following: a) sheet, wire and woven or welded mesh products that are continuously hot dip galvanized; b) tube and pipe that are hot dip galvanized in automatic plants; c) hot dip galvanized products (e.g. fasteners) for whi

34、ch specific standards exist and which might include additional requirements or requirements which are different from those of this International Standard. NOTE Individual product standards can incorporate this International Standard for the coating by quoting its number, or can incorporate it with m

35、odifications specific to the product. Different requirements can also be made for galvanized coatings on products intended to meet specific regulatory requirements. After-treatment/over-coating of hot dip galvanized articles is not covered by this International Standard. 2 Normative references The f
