19、nternational 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
20、 with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directi

28、des, strip electrodes, wires and rods for arc welding of stainless and heat resisting steels. It recognizes that there are two somewhat different approaches in the global market to classifying a given welding consumable, and allows for either or both to be used, to suit a particular market need. Man
29、y, but not all, commercial products addressed by this document can be classified using both approaches, and suitable products can also be marked.System A uses the nominal composition approach with designators to indicate the principal alloying elements at their nominal levels, in a particular sequen
30、ce, and which is sometimes followed by chemical element symbols to indicate compositional modifications to the original grade. System B uses the alloy type approach with three- or four-digit designations for certain grades, sometimes followed by one or more chemical element symbols indicating compos
31、itional modifications of the grade. In both approaches, classification is based upon the chemical composition of the product. In many cases, a given product can be classified using both approaches, because the composition ranges, although slightly different, overlap to a considerable extent between
32、the two.For stainless steel welding consumables, there is no unique relationship between the product form (wire electrode, strip electrode, wire or rod) and the welding process used (gas-shielded metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, electroslag weld
33、ing and laser beam welding). For this reason, the wire electrodes, strip electrodes, wires or rods can be classified on the basis of any of the above product forms and can be used, as appropriate, for more than one of the above processes.Classification according to system A, by nominal composition,
34、is based mainly on EN 120721, while that of system B, by alloy type, is mainly based upon standards used around the Pacific Rim.

36、r beam welding of stainless and heat-resisting steels. The classification of the wire electrodes, strip electrodes, wires and rods is based upon their chemical composition.This document is a combined specification providing for classification utilizing a system based upon nominal composition (system
37、 A), or utilizing a system based upon alloy type (system B).a) Paragraphs which carry the label “classification according to nominal composition” and the suffix letter “A”, or “ISO 14343-A”, are applicable only to products classified according to system A;b) Paragraphs which carry the label “classif
38、ication according to alloy type” and the suffix letter “B”, or “ISO 14343-B”, are applicable only to products classified according to system B.c) Paragraphs which carry neither label nor suffix letter are applicable to products that can be classified according to either system A or B or both.2 Norma
