introduction This International Standard takes into account two slightly differing ways in the world market for the classification of a given wire electrode and allows one or both apply to meet specific market requirements . The application of a classification to describe ( or both , if applicable) identifies a product as classified according to this International Standard. This International Standard provides a classification for the description of wire electrodes according to their chemical composition and - where necessary - according to the yield strength , tensile strength and elongation at break of the pure weld metal . The ratio of yield strength to tensile strength of the weld metal is generally higher than that for the base material . Users should note that a weld that reaches the yield strength of the base material , not necessarily reached its tensile strength . If an application requires the achievement of tensile strength , therefore, the column 3 in Table 1A or Table 1B must be considered in the selection of the filler . It should be noted that the used for the classification of wire electrodes me chanical properties of allweld differ from those that are reached in production welding . This is due to differences in the implementation of the welding, such as , for example, electrode diameter , weaving width , the welding position and material composition.

1 scope This International Standard specifies requirements for classification of wire electrodes and deposits for gas shielded metal arc welding of non alloy and fine grain steels with a minimum yield strength up to 500 MPa or a minimum tensile strength to 570 MPa in the as-welded condition and after heat treatment. A wire electrode can be tested and classified with different shielding gases. This International Standard provides a common specification for the classification according to eithe r of the yield strength and the average impact energy of 47 J of all-weld or after the tensile strength and the average impact energy of 27 J of all-weld . a)Sections and tables , characterized by a suffix "A" can only be used for wire electrodes , which are divided by the yield strength and the average impact energy of 47 J of all-weld metal according to this International Standard. b )Sections and tables , characterized by a trailing 'B' can be applied only for wire electrodes , which are divided by the tensile strength and the average impact energy of 27 J of all-weld metal according to this International Standard. c )Sections and tables that do not contain a suffix "A" or "B" are applicable to all classified according to this International Standard wire electrodes.

The two options for t he designation include other additives for other requirements for the classification , this is not true for all , as shown in the following sections. In most cases , a given commercial product are classified according to t wo systems. In this case one of the two , or both of the classification can be used for this product.

6 Chemical analysis Chemical analysis has to be carried out on samples of the wire. Each analytical method may be applied. In case of dispute , they must be performed according to published procedures introduced . In chemical elements , which do not change during manufacturing, the chemical analysis of the wire may be replaced by an analysis of the product during the process or at the output material or by a report on the Heat analysis of the starting material. 6A Classification by yield strength and notch impact energy of 47 J The results of chemical analysis must meet the requirements for classification in Table 3A . 6B Classification by tensile strength and notch impact energy o f 27 J The results of chemical analysis must meet the requirements for classification in Table 3B .
7Method for rounding In order to achieve compliance with the requirements of this International Standard , the present measured values according to the rules of ISO 80000-1:2009 , Section B.3, Rule A , are to be rounded . If the measured values determined with a device that was calibrated according to units other than in accordance with this International Standard , the measured values must be converted according to this International Standard in the units prior to rounding . If an average value with the requirements of this International Standard is to be compared to round only after calculation of the mean. When cited in Section 2 test standard includes instructions for rounds that are inconsistent with the instructions of this International Standard , the rounding rules of the test standards must be applied. The rounded test results shall meet the requirements of the appropriate table for division .
8 repeat tests If the results of a test do not meet the requirements, then this test shall be repeated twice. The results of both retests shall meet the requirements. Samples for periodic testing can be found in the original specimen or a new one. For the chemical analysis, a repeat is required only for those items that did not meet the requirement. If the results of one or both retests the request does not comply , then the tested filler must be considered that he did not meet the requirements of this standard for the classification . Is it clearly stated during the test or after that were not complied with in the manufacture of the test , the sample (s ) or prescribed in the test procedure or proper specifications , then the test is considered invalid . In this case, no consideration is given to whether the audit was completed or if the test results meet the requirements or not . This test shall be repeated in compliance with t he properly prescribed specifications. In this case, the requirement is omitted after the double number of samples .
