19、(E)ForewordISO (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
20、 technical 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 matte
21、rs of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This docu
22、ment was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

Other prop
28、erties of the electrodes are specified by reference to tables.This International Standard 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. A
29、pplication of either (or both) type(s) of classification designation identifies a product as classified according to this International Standard. It is important to note that the two systems are not exactly equivalent; therefore, each system must be used independent of the other, without combining d
30、esignators in any way.The classification according to ISO 3581, system A, is mainly based upon EN 1600 while the classification according to ISO 3581, system B, is mainly based upon standards used around the Pacific Rim.

32、 electrode 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 classifi
33、cation 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
34、 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 referencesThe foll

40、ating the chemical composition of the all-weld metal deposit obtained with 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 level
41、s of other elements, whose levels are not conveniently expressed as integers. The “alloy type” approach uses tradition-based three-digit or four-digit designations for alloy families, and occasionally an additional character or characters for compositional modifications of each original alloy within
42、 the family. Both designation approaches include additional designators for some other classification requirements, but not entirely the same classification requirements, as will be clear from the following clauses.Table 1 lists the tests required for classification of an electrode in each approach.
43、In many cases, a given commercial product can be classified using both approaches. Then either or both classification designations can be used for the product.Table 1 Summary of test requirementsElectrode designationSize ammPosition of weldingbChemical analysis test All-weld metal tension testFillet
