BS EN ISO 26304:2018规定了实心线电极、管状药芯电极、，以及最小屈服强度大于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的焊剂组合（全焊缝金属沉积物）。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。本文件是一份综合规范，规定使用基于屈服强度和47 J平均冲击能的系统对所有材料进行分类- 焊接金属，或使用基于全焊接金属拉伸强度和平均冲击能量27 J的系统。a） 带有后缀字母“a”的条款、子条款和表格仅适用于实心焊丝焊条、管状药芯焊条和根据屈服强度和47 J的平均冲击能量分类为该系统的全焊缝金属熔敷层，这些熔敷层是根据本文件使用焊剂组合获得的。b） 带有后缀字母“b”的条款、子条款和表格仅适用于实心焊丝、管状药芯焊丝和根据抗拉强度和27 J的平均冲击能量分类为该系统的全焊接金属熔敷层- 根据本文件，使用焊条焊剂组合获得的焊接金属。c） 没有后缀字母“A”或后缀字母“B”的条款、子条款和表格适用于根据本文件分类的所有实心线电极、管状药芯电极和电极焊剂组合。出于比较目的，一些表格包括按照两个系统分类的电极要求，将两个系统中成分和性能相似的单个电极放置在特定表格的相邻行上。在一个系统中必须使用的特定表格行中，括号中显示了另一个系统中类似电极的符号。 通过对特定电极配方的适当限制，通常（但并非总是）可以生产出可在两个系统中分类的电极，在这种情况下，电极或其包装可在其中一个或两个系统中标记分类。交叉引用:ISO 14174ISO 14344ISO 3690ISO 13916ISO 6847ISO 544ISO 80000-1:2009/Cor 1:2011ISO 15792-1:2000 Ed 1（R10）ISO 80000-1:2009 Ed 1ISO 14171EN 14295购买本文件时提供的所有现行修订均包含在购买本文件中。

BS EN ISO 26304:2018 specifies requirements for classification of solid wire electrodes, tubular cored electrodes, and electrode-flux combinations (the 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.This document is a combined specification providing for classification utilizing a system based on the yield strength and average impact energy of 47 J for the all-weld metal, or utilizing a system based on the tensile strength and average impact energy of 27 J for the all-weld metal.a) Clauses, subclauses and tables which carry the suffix letter "A" are applicable only to solid wire electrodes, tubular cored electrodes and the all-weld metal deposits classified to the system based on the yield strength and the average impact energy of 47 J for the all-weld metal obtained with electrode-flux combinations in accordance with this document.b) Clauses, subclauses and tables which carry the suffix letter "B" are applicable only to solid wire electrodes, tubular cored electrodes and the all-weld metal deposits classified to the system based on the tensile strength and the average impact energy of 27 J for the all-weld metal obtained with electrode-flux combinations in accordance with this document.c) Clauses, subclauses and tables which do not have either the suffix letter "A" or the suffix letter "B" are applicable to all solid wire electrodes, tubular cored electrodes and electrode-flux combinations classified in accordance with this document.For comparison purposes, some tables include requirements for electrodes classified in accordance with both systems, placing individual electrodes from the two systems, which are similar in composition and properties, on adjacent lines in the particular table. In a particular line of the table that is mandatory in one system, the symbol for the similar electrode from the other system is indicated in parentheses. By appropriate restriction of the formulation of a particular electrode, it is often, but not always, possible to produce an electrode that can be classified in both systems, in which case the electrode, or its packaging, can be marked with the classification in either or both systems.Cross References:ISO 14174ISO 14344ISO 3690ISO 13916ISO 6847ISO 544ISO 80000-1:2009/Cor 1:2011ISO 15792-1:2000 Ed 1 (R10)ISO 80000-1:2009 Ed 1ISO 14171EN 14295All current amendments available at time of purchase are included with the purchase of this document.
