T

24、he 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. International organizations, governmental and non-go

25、vernmental, 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 rules given in the ISO/IEC Directives, Part 2.

26、 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 at least 75 % of the member bodies casting a v

30、ernational Standard proposes a method for classification of covered electrodes, in terms of chemical composition of the all-weld metal (system A) and in terms of tensile strength and chemical composition (system B). The mechanical properties of all-weld metal test specimens used to classify the elec

31、trodes 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 according to system A is mainly based on EN 1599:19971. The classification according to system B

32、is mainly based upon standards used around the Pacific Rim.

34、s Classification 1 Scope This International Standard 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. This In

35、ternational Standard 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 c

36、omposition 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 International Standard.

37、 b) Paragraphs and tables 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 International Standard. c) Paragraphs and tables which do not have either the suffix letter

38、 “A” or the suffix letter “B” are applicable to all covered electrodes classified under this International Standard. 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

39、 composition and properties, on adjacent lines in the particular 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,

40、it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, and/or its packaging, may be marked with the classification in either or both systems. 2 Normative references The following referenced documents are indispensable for th

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 i

47、n both systems. Then either or both classification designations can be used for the product. The classification includes all-weld metal properties obtained with a covered electrode as given in 3A and 3B. The classification is based on the electrode size 4,0 mm with the exception of the symbol for we

48、lding position which is based on ISO 15792-3. 3A Classification by chemical compositionThe classification is divided into six parts: 1) the first part gives a symbol indicating theproduct/process to be identified; 2) the second part gives a symbol indicating thechemical composition of the all-weld metal (seeTable 1); 3) the third part gives a symbol indicating the typeof electrode covering (see 4.4A); 4) the fourth part gives a symbol indicating thenominal electrode efficiency and type of current (seeTable 4A); 5) the fifth part gives a symbol indicating t
