40、material The designation of the symbol for the auxiliary material shall follow the EN ISO 14175:2008, Table 2, for shielding gases and the EN ISO 14174:2012, Table 1, for fluxes. If metal or flux cored wires will be used without gas protection, the symbol “NO” is applicable. 5 Alloy types, form of s
41、upply, requirements and applications The most usual alloy types are listed in Table 2. Typical application is given in Table A.1. The forms of supply listed in Tables A.2 and A.3 may support the decision making as regards applicable welding processes. The applications shown in Table A.4 give referen
42、ce to the suitability of individual alloy types for different kind of requirements and system structures. It may be concluded that other alloy types may also be considered with regard to complex kind of requirements. 6 Chemical composition The chemical analysis shall be performed on specimens of sol
43、id wires, solid rods and solid strips according to EN ISO 6847 respectively or on any suitable all-weld metal specimen and cast rods (covered electrodes, cored wires, cored strips, sintered rods, sintered strips and metal powder). Any analytical technique can be used, but in case of dispute referenc
44、e shall be made to established published methods. NOTE See Bibliography. 7 Rounding off procedure For purposes of determining compliance with the requirements of this European Standard, the actual test values obtained shall be subjected to the rounding-off rules of EN ISO 80000-1:2013, Annex B, Rule
45、 A. If the measured values are obtained by equipment calibrated in units other than those of this standard, the BS EN 14700:2014EN 14700:2014 (E) 8 measured values shall be converted to the units of this standard before rounding off. If an average value is to be compared to the requirements of this
46、document, rounding off shall be done only after calculating the average. In the case where the testing document cited in the normative references of this European Standard contains instructions for rounding off that conflict with the instructions of this standard, the rounding off requirements of th
47、e testing document 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 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, retest need be only for those specific elements that failed to meet their test requirement. If the results of one ore both retests fail to meet the requirement, the mate
