System A classification mainly reflects
7、the European approach, while classification according to system B is mainly based on standards used around the Pacific Rim. It should be noted that, when using this standard, the classification system (A or B) according to which welding consumables are to be manufactured or supplied must be laid dow

30、 Technical Committee ISO/TC 44 “Welding and allied processes” in collaboration with Technical Committee CEN/TC 121 “Welding” the secretariat of which is Introduction This International Standard recognizes that there are two somewhat different approaches in the global market to classifying a given el
31、ectrode, and allows for either or both to be used, to suit a particular market need. Application of either type of classification designation (or of both, where suitable) identifies a product as classified in accordance with this International Standard. The classification in accordance with system A
32、 is mainly based on EN 499:19941. The classification in accordance with system B is mainly based upon standards used around the Pacific Rim. This International Standard provides a classification in order to designate covered electrodes in terms of the yield strength, tensile strength and elongation
33、of the all-weld metal. The ratio of yield strength to tensile strength of weld metal is generally higher than that of parent metal. Users should note that matching weld metal yield strength to parent metal yield strength does not necessarily ensure that the weld metal tensile strength matches that o
34、f the parent metal. Therefore, where the application requires matching tensile strength, selection of the consumable should be made by reference to column 3 of Table 1A or to Table 1B and Table 8B. It should be noted that the mechanical properties of all-weld metal test specimens used to classify th
35、e electrodes vary from those obtained in production joints because of differences in welding procedure such as electrode size, width of weave, welding position, welding current, interpass temperature and parent metal composition. DIN EN ISO 2560:2010-03 4 EN ISO 2560:2009 (E) 1 Scope This Internatio
36、nal Standard specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of non-alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile
37、strength of up to 570 MPa. This International Standard is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energ
38、y of 27 J of all-weld metal. a) Paragraphs and tables which carry the suffix letter “A” are applicable only to covered electrodes classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in this International Standard. b) Paragraphs and tables wh
39、ich carry the suffix letter “B” are applicable only to covered electrodes classified to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in this International Standard. c) Paragraphs and tables which do not have either the suffix letter “A” or the su
40、ffix letter “B” are applicable to all covered electrodes classified in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

45、lassification Classification designations are based upon two approaches to indicate the tensile properties and the impact properties of the all-weld metal obtained with a given electrode. The two designation approaches include additional designators for some other classification requirements, but no
46、t all, as is clear from the following subclauses. In most cases, a given commercial product can be classified in 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
47、 below. The classification is based on an electrode size of 4,0 mm, with the exception of the symbol for welding position, which is based on ISO 15792-3. Where the defined diameter has not been manufactured, the closest diameter to 4,0 mm shall be used for all-weld metal tests. 3A Classification by
48、yield strength and 47 J impact energy 3B Classification by tensile strength and 27 J impact energy The classification is divided into eight parts: The classification is divided into seven parts: 1) the first part gives a symbol indicating theproduct/process to be identified; 2) the second part gives
49、 a symbol indicating thestrength and elongation of all-weld metal (seeTable 1A); 3) the third part gives a symbol indicating theimpact properties of all-weld metal (see Table 2A); 4) the fourth part gives a symbol indicating thechemical composition of all-weld metal (see Table 3A); 5) the fifth part gives a symbol indicating the typeof electrode covering (see 4.5A); 6) the sixth part gives a symbol indicating thenominal electrode efficiency and type of current (seeTable 5A); 7) the
