23、ional 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 represented on that committee. Interna

24、tional 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 drafted in accordance with the r

25、ules 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 International Standard requires approval by a

26、t 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. ISO 3581 was prepared in collaboration with the Int

27、ernational Institute of Welding which has been approved by the ISO Council as an international standardizing body in the field of welding. This second edition cancels and replaces the first edition (ISO 3581:1976), which has been technically revised. Copyright European Committee for Standardization

29、ectrodes in terms of chemical composition of deposited weld metal and type of electrode covering. Other properties of the electrodes are specified by reference to tables. This International Standard has been prepared by the International Institute of Welding, Commission II “Arc Welding”, Subcommissi

30、on II-E. It recognizes that there are two somewhat different approaches in the global market, for classifying a given stainless steel, covered electrode, and allows for either or both to be used to suit a particular need. Application of either (or both) type(s) of classification designation identifi

31、es a product as classified according to this International Standard. It should be noted that the two systems are not exactly equivalent, therefore each system must be used independent of the other, without combining designators in any way. The classification according to ISO 3581, system A, is mainl

32、y based upon EN 1600; the classification according to ISO 3581, system B, is mainly based upon standards used around the Pacific Rim.

34、s Covered electrodes for manual metal arc welding of stainless and heat-resisting steels Classification 1 Scope This International Standard specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other elec

35、trode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels. This International Standard is a combined standard providing for classification utilizing a system based upon classificati

36、on according to nominal composition, or utilizing a system based upon classification according to alloy type. a) Paragraphs and tables which carry the label “classification according to nominal composition” or “ISO 3581-A” are applicable only to products classified to that system. b) Paragraphs and

37、tables which carry the label “classification according to alloy type” or “ISO 3581-B” are applicable only to products classified to that system. c) Paragraphs and tables which carry neither label are applicable to products classified according to either or both systems. 2 Normative references The fo

44、ith a given electrode. The “nominal composition” approach uses designation components indicating directly the nominal levels of certain alloying elements, given in a particular order, and some symbols for low but significant levels of other elements, whose levels are not conveniently expressed as in

45、tegers. The “alloy type” approach uses tradition-based three- or four-digit designations for alloy families, and an occasionally additional character or characters for compositional modifications of each original alloy within the family. Both designation approaches include additional designators for

46、 some other classification requirements, but not entirely the same classification requirements, as will be clear from the following sections. Table 1 lists the tests required for classification of an electrode in each approach. In many cases, a given commercial product can be classified using both a

47、pproaches. Then either or both classification designations can be used for the product.
