BS EN ISO 3580:2017根据热处理条件下的所有焊接金属，规定了用于铁素体和马氏体抗蠕变钢和低合金高温钢手工金属电弧焊的焊条分类要求。本文件是一份综合分类规范，使用基于全焊缝金属化学成分的系统，对全焊缝金属的屈服强度和冲击能有要求，或使用基于全焊缝金属抗拉强度和化学成分的系统- 焊接金属。a） 带有后缀字母的段落和表格？A.仅适用于根据化学成分分类到系统中的焊条，本文件要求所有焊缝金属的屈服强度和冲击能量。b） 带有后缀字母“b”的段落和表格仅适用于根据本文件下所有焊接金属的抗拉强度和化学成分分类为系统的焊条。c） 没有后缀字母“A”或后缀字母“B”的段落和表格适用于根据本文件分类的所有覆盖电极。 出于比较目的，一些表格包括根据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。通过对特定电极的配方进行适当限制，通常（但并非总是）可以生产可在两个系统中分类的电极，在这种情况下，电极和/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 80000-1:2009 Ed 1ISO 2401ISO 15792-1:2000 Ed 1（R10）ISO 544:2011 Ed 4ISO 14344:2010 Ed 2ISO 6847:2013 Ed 3ISO 13916:1996ISO 3690:2012 Ed 3ISO 15792-3:2011 Ed 2ISO 6947:2011 Ed 3 EN 1599:1997购买本文件时提供的所有当前修订版均包括在内。

BS EN ISO 3580:2017 specifies requirements for classification of covered electrodes, based on the all-weld metal in the heat-treated condition, for manual metal arc welding of ferritic and martensitic creep-resisting and low alloy elevated temperature steels.This document is a combined specification for classification utilizing a system based upon the chemical composition of the all-weld metal, with requirements for the yield strength and impact energy of the all-weld metal, or utilizing a system based upon the tensile strength and the chemical composition of the all-weld metal.a) Paragraphs and tables which carry the suffix letter?A?are applicable only to electrodes classifiedto the system based upon chemical composition, with requirements for the yield strength andimpact energy of the all-weld metal under this document.b) Paragraphs and tables which carry the suffix letter "B" are applicable only to electrodes classifiedto the system based upon the tensile strength and the chemical composition of all-weld metal underthis document.c) Paragraphs and tables which do not have either the suffix letter "A" or the suffix letter "B" areapplicable to all covered electrodes classified under this document.For comparison purposes, some tables include requirements for electrodes classified according to 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, and/or its packaging, can be marked with the classification in either or both systems.Cross References:ISO 80000-1:2009 Ed 1ISO 2401ISO 15792-1:2000 Ed 1 (R10)ISO 544:2011 Ed 4ISO 14344:2010 Ed 2ISO 6847:2013 ED3ISO 13916:1996ISO 3690:2012 ED3ISO 15792-3:2011 Ed 2ISO 6947:2011 Ed 3 EN 1599:1997All current amendments available at time of purchase are included with the purchase of this document.
