ISO 17632:2015规定了非合金钢和细晶粒钢在焊态或焊后热处理条件下进行金属电弧焊时，最小屈服强度高达500 MPa或最小抗拉强度高达570 MPa的带或不带气体保护层的管状药芯焊条的分类要求。一个管状药芯电极可以用不同的保护气体（如果有的话）进行测试和分类。 本国际标准是一个综合规范，使用基于屈服强度和47 J平均冲击能量的系统进行分类- 焊接金属或使用基于所有焊接金属的抗拉强度和27 J的平均冲击能量的系统。 1） 带有后缀字母“A”的段落和表格仅适用于根据本国际标准所有焊缝金属的屈服强度和47 J的平均冲击能量分类为系统的管状药芯焊条。 2） 带有后缀字母“B”的段落和表格仅适用于根据抗拉强度和27 J的平均冲击能量分类为系统的管状药芯焊条- 按照本国际标准焊接金属。 3） 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国际标准分类的所有管状药芯焊条。 众所周知，管状药芯电极的工作特性可以通过使用脉冲电流进行修改，但就本国际标准而言，不允许使用脉冲电流来确定电极分类。

ISO 17632:2015 specifies requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of non-alloy and fine grain steels in the as-welded condition or in the post-weld heat-treated condition with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if any.

This International Standard is a combined specification providing classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.

1) Paragraphs and tables which carry the suffix letter "A" are applicable only to tubular cored electrodes classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard.

2) Paragraphs and tables which carry the suffix letter "B" are applicable only to tubular cored electrodes classified to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal in accordance with this International Standard.

3) Paragraphs and tables which have neither the suffix letter "A" nor the suffix letter "B" are applicable to all tubular cored electrodes classified in accordance with this International Standard.

It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but for the purposes of this International Standard, pulsed current is not permitted for determining the electrode classification.
