21、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 be represented on that committee. I

22、nternational 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.The procedures used to develop this document and those

23、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.

31、ystem B).The mechanical properties of all-weld metal test specimens used to classify the electrodes vary from those obtained in production joints because of differences in welding procedure such as electrode diameter, width of weave, welding position and material composition.The classification accor

32、ding to system A is mainly based on EN 15991. The classification according to system B is mainly based upon standards used around the Pacific Rim.

33、creep-resisting steels Classification1 ScopeThis document specifies requirements for classification of covered electrodes, based on the all-weld metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creep-resisting and low alloy elevated temperature steels.Thi

34、s document is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and impact energy of the all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition

35、 of the all-weld metal.a) Paragraphs and tables which carry the suffix letter “A” are applicable only to electrodes classified to the system based upon chemical composition, with requirements for the yield strength and impact energy of the all-weld metal under this document.b) Paragraphs and tables

36、which carry the suffix letter “B” are applicable only to electrodes classified to the system based upon the tensile strength and the chemical composition of all-weld metal under this document.c) Paragraphs and tables which do not have either the suffix letter “A” or the suffix letter “B” are applica

37、ble to all covered electrodes classified under this document.For comparison purposes, some tables include requirements for electrodes classified according to both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the pa

38、rticular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an elec

39、trode that can be classified in both systems, in which case the electrode, and/or its packaging, can be marked with the classification in either or both systems.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requi

46、ition and properties of the all-weld metal obtained with a given electrode. The two designation approaches include additional designators for some other classification requirements, but not all. In most cases, a given commercial product can be classified in both systems. Then either or both classifi

47、cation designations can be used for the product.The classification includes all-weld metal properties obtained with a covered electrode as given in 4A and 4B. The classification is based on the electrode size 4,0 mm with the exception of the symbol for welding position which is based on ISO 15792-3.

The classification is divided into five parts.1) The first part gives a symbol indicating the product/process to be identified.1) The first part gives

49、 a symbol indicating the product/process to be identified.2) The second part gives a symbol indicating the chemical composition of the all-weld metal (see Table 1).2) The second part gives a symbol indicating the strength of the all-weld metal (see Table 2).3) The third part gives a symbol indicating the type of electrode covering (see 5.4A).3) The third part gives a symbol indicating the type of electrode covering, the type of current, and the welding position (see Table 3B).4) The fourth part gives a
