The 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 establishe
19、d has the right to be 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.T

29、3 ClassificationA covered electrode shall be classified according to the chemical composition of the all-weld metal as given in Table 1. The symbol for the classification is divided into two parts:a) the first part gives a symbol indicating the product/process to be used;b) the second part gives a s

40、rformed on any suitable all-weld metal test specimen. In case of dispute, the test specimen specified in ISO 6847 shall be used. Any analytical technique may be used, but in case of dispute, reference shall be made to established published methods.6 Rounding procedureFor purposes of determining comp
41、liance with the requirements of this International Standard, the 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
42、 to the units of this International Standard before rounding. If 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 appropri
43、ate table for the classification under test.7 RetestsIf any test fails to meet a 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 analysi
44、s, 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 considered as not meeting the requirements of this International Standard for that classification.In th
45、e event that, during preparation or after completion of any test, it is clearly determined that the prescribed or proper procedures were not followed in preparing the sample or test specimen(s), or in conducting the tests, the test shall be considered invalid, without regard to whether the test was
46、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 the number of test specimens does not apply.8 Technical delivery conditionsTechnical delivery condi
