适用范围:1.1 This comparison standard is meant to serve as a guide to the selection of near equivalent indigenous and overseas ( or υice-υersa ) welding filler materials on the basis of the classification systems of the respective countries ( see Table 1 ).1.1.1 Individual countries have individual basis for classification and coding of welding consumables. Individual countries emphasis on such chemical composition, mechanical and other properties for the welding filler material as will meet the service and other needs as may be prevalent in those countries.1.1.2 Symbols and digits used by the individual countries in their standards for the classification and coding of welding consumables have been explained in Appendix A.1.1.3 The technical details available for a particular type or all types of electrodes in the specification of one country, may not match in totality with the similar or all types of filler materials listed in the specification of other countries.1.1.4 Keeping this possible and logical differences in view, this comparison standard has been compiled. This comparison is meant only to serve as a guide and it is not meant to serve as a standard specification.1.1.5 Table 1 lists the comparison of codes for mild steel and medium tensile steel electrodes.1.1.6 This comparison standard does not mean in any form to uphold, contradict or comment on the quality of individual welding consumable' or the standards, specifications and codes of procedures of all those countries whose specification codes have been referred to in this comparison standard. It does not give complete information on any national standard cited in Table 1 or the properties and other characteristics of the electrodes and, as such the respective national standard must be referred to for complete information and application purposes.
