标准范围

ISO 26304:2008规定了最小屈服强度大于500 MPa或最小抗拉强度大于570 MPa的高强度钢埋弧焊焊态和焊后热处理状态下实心焊丝、管状药芯焊丝和焊条/焊剂组合（所有焊缝金属沉积物）的分类要求。一种焊剂可以用不同的电极进行测试和分类。一个电极可以用不同的焊剂进行测试和分类。固体丝电极也根据其化学成分单独分类。ISO 26304:2008是一个组合规范，规定了使用基于屈服强度和平均冲击能量47 J的系统对所有焊缝金属进行分类，或使用基于拉伸强度和平均冲击能量27 J的系统对所有焊缝金属进行分类-焊接金属。

ISO 26304:2008 specifies requirements for classification of solid wire electrodes, tubular cored electrodes, and electrode/flux combinations (all-weld metal deposits) in the as-welded condition and in the post weld heat-treated condition for submerged arc welding of high strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa. One flux can be tested and classified with different electrodes. One electrode can be tested and classified with different fluxes. The solid wire electrode is also classified separately based on its chemical composition.ISO 26304:2008 is a combined specification providing for classification utilizing a system based upon the yield strength and average impact energy of 47 J for all-weld metal, or utilizing a system based upon the tensile strength and average impact energy of 27 J for all-weld metal.
