23、Kingdom. Endorsement notice The text of ISO 24373:2008 has been approved by CEN as EN ISO 24373:2009 without any modification. Introduction For copper-welding consumables, there is no unique relationship between the product form (solid wire or rod) and the welding process used (e.g. gas-shielded met
24、al arc welding, gas tungsten arc welding, plasma arc or other welding processes). For this reason, the solid wires or rods may 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. ISO 24373 is based on EN 14640:2005.
25、4 DIN EN ISO 24373:2009-08EN ISO 24373:2009 (E)1 Scope This International Standard specifies requirements for classification of solid wires and rods for fusion welding of copper and copper alloys. The classification of the solid wires and rods is based on their chemical composition. 2 Normative refe
26、rences The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 31-0:1992, Quantities and units Part 0

28、s shielded electrical welding processes Procurement guidelines for consumables 3 Classification The classification is divided into two parts: a) the first part indicates the product form, solid wires or rods (see 4.1); b) the second part gives a numerical symbol indicating the chemical composition o
29、f the solid wire or rod (see Table 1). 4 Symbols 4.1 Symbol for the product form The symbol for the solid wire and rod shall be S. NOTE One product form may be used for more than one welding process. 5 EN ISO 24373:2009 (E) DIN EN ISO 24373:2009-084.2 Symbol for the chemical composition The numerica
30、l symbol in Table 1 indicates the chemical composition of a solid wire or rod, determined under conditions given in Clause 6. NOTE 1 In addition the chemical symbol may be used. NOTE 2 Corresponding national classifications are shown in Annex A. 5 Mechanical properties of the weld metal The mechanic
31、al properties of the weld metal are not part of the classification. 6 Chemical analysis Chemical analysis shall be performed on specimens of the product or the stock from which it is made. Any analytical technique can be used; but, in case of dispute, reference shall be made to established published
32、 methods, agreed between the contracting parties. 7 Rounding-off procedure For purposes of determining compliance with the requirements of this International Standard, the actual test values obtained shall be subjected to the rounding-off rules of ISO 31-0:1992, Annex B, Rule A. If the measured valu
33、es are obtained by equipment calibrated in units other than those of this International Standard, the measured values shall be converted to the units of this International Standard before rounding off. If an average value is to be compared to the requirements of this International Standard, rounding
34、 off shall be done only after calculating the average. In the case where the testing standard cited in the normative references of this International Standard contains instructions for rounding off that conflict with the instructions of this International Standard, the rounding off requirements of t
35、he testing standard shall apply. The rounded-off results shall fulfil the requirements of the appropriate table for the classification under test. 8 Retest If any test fails to meet a requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimens fo
36、r the retest may be taken from the original test sample or from a new test sample. For chemical analysis, retests need only be for those specific elements that failed to meet their test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be
37、considered as not meeting the requirements of this International Standard for that classification. In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the sample or test specimen(s), or in
38、 conducting the tests, the test shall be considered invalid, without regard to whether the test was actually completed, or whether the test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling
39、 the number of test specimens does not apply. 9 Technical delivery conditions Technical delivery conditions shall meet the requirements in ISO 544 and ISO 14344. 6 DIN EN ISO 24373:2009-08EN ISO 24373:2009 (E)Table 1 Symbol for the chemical composition of solid wires and rods Alloy symbols Chemical
