Each member body interested in a subject for which a technical committee has been established has the right to be
19、represented on that committee. International 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
20、develop this document and those 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. This document was drafted in accordance with the editorial rules of the

26、 (solid wire electrodes, solid wires or rods) and the welding process used (gas-shielded metal arc welding, tungsten inert gas arc welding, plasma arc welding or laser beam welding). For this reason, solid wire electrodes, solid wires and rods may be classified in terms of their chemical composition
27、.In this International Standard, the symbol of the welding process is not used becausea) different joining processes are performed with the same chemical component consumable, andb) the producer is not able to determine the process symbol before shipping.Mechanical properties of all-weld metal test
28、specimens or welded joints will vary from those obtained in production due to differences in welding procedure and the parent material. Mechanical properties of all-weld metal or welded joints are consequently not specified. ISO 2016 All rights reserved vBS EN ISO 19288:2016BS EN ISO 19288:2016Weldi
29、ng consumables Solid wire electrodes, solid wires and rods for fusion welding of magnesium and magnesium alloys Classification1 ScopeThis International Standard specifies requirements for the classification of solid wire electrodes, solid wires and rods for fusion welding of magnesium and magnesium
30、alloys. The classification is based on their chemical composition.The compositions of solid wire electrodes for metal inert gas (MIG) welding are the same as solid wire electrodes, solid wires and rods for tungsten inert gas (TIG) arc welding, plasma arc welding, laser beam welding, laser-MIG hybrid
31、 welding and other fusion welding processes.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of t
32、he referenced document (including any amendments) applies.ISO 544, Welding consumables Technical delivery conditions for filler materials and fluxes Type of product, dimensions, tolerances and markingsISO 14344, Welding consumables Procurement of filler materials and fluxesISO 80000-1:2009, Quantiti
33、es and units Part 1: General. Corrected by ISO 80000-1:2009/Cor 1:20113 ClassificationThe classification is divided into two parts as follows:a) the first part gives a symbol indicating the product to be identified (see 4.1);b) the second part gives a symbol indicating the chemical composition of th
34、e solid wire electrodes,solid wires and rods (see Table 1).4 Symbols and requirements4.1 Symbol for the productThe symbol for the solid wire electrodes, solid wires and rods shall be S.4.2 Symbol for the chemical compositionThe numerical symbols in Table 1 indicate the chemical composition of a soli
35、d wire or rod, determined under the conditions given in Clause 6. The first two digits indicate the alloy group. See Annex A for an explanation of the numerical symbols.The optional additional chemical symbols in Table 1 indicate the chemical composition and include an indication of the characterist
36、ic alloying elements.INTERNATIONAL STANDARD ISO 19288:2016(E) ISO 2016 All rights reserved 1BS EN ISO 19288:2016ISO 19288:2016(E)5 Mechanical propertiesMechanical properties of all-weld metal or welded joints are not part of this classification.6 Chemical analysisChemical analysis shall be performed
37、 on specimens of the product or the stock from which it is made. Any analytical technique may be used but, in cases of dispute, reference shall be made to established published methods.7 Rounding procedureFor purposes of determining compliance with the requirements of this International Standard, th
38、e actual test values obtained shall be subject to ISO 80000-1:2009, B.3, Rule A. If the measured values 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. I
39、f an arithmetic average value is to be compared with the requirements of this International Standard, rounding shall be done only after calculating the arithmetic average. The rounded results shall fulfil the requirements of the appropriate table for the classification under test.8 RetestIf any test
40、 fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimens for the retest may be taken from the original test sample or from a new test sample. For chemical analysis, retests need be only for those specific elements that faile
41、d to meet their test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirements of this specification for that classification. In the event that, during preparation or after completion of any test, it i
42、s clearly determined that prescribed or proper procedures were not followed in preparing the weld test sample or test specimen(s), or in 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 t
43、o meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling the number of test specimens does not apply.9 Technical delivery conditionsTechnical delivery conditions shall meet the requirements of ISO 544 and ISO 14344 (but
44、when Schedule 4 is specified, only chemical composition is required).2 ISO 2016 All rights reservedBS EN ISO 19288:2016ISO 19288:2016(E)Table1 Chemical composition requirementsAlloy symbolsChemicalcomposition, % (by mass)aNumericalChemicalMgAlZnMnSiCuNiFeCaBeOthersbMg0602AMgAl6Mnbal.5,5 to 6,50,300,
