IEC 62641:2022规定了等效直径的圆形和成型线材的机械和电气性能，铝和铝合金的值不超过表3，耐热合金的值不超过表4。本文件适用于制造用于输电目的的带或不带间隙的同心架空电绞合导线的铝和铝合金导线。 表1中列出了各种材料及其名称。出于计算目的，使用表1中列出的值。 本第一版取消并取代了1987年出版的IEC 60104第二版、1960年出版的IEC 60121第一版、1987年出版的IEC 60889第一版和2007年出版的IEC 62004第一版。本版构成技术修订版。 与IEC 60104、IEC 60121、IEC 60889和IEC 62004的先前版本相比，本版本包括以下重大技术变更: 铝合金的名称被修改； 添加铝合金A4、AL4和AL5； 用于指示机械性能的线径范围被修改和扩展； 合并测试方法。

IEC 62641:2022 specifies the mechanical and electrical properties of round and formed wires for equivalent diameters up to the values according to Table 3 for aluminium and aluminium alloys and according to Table 4 for thermal resistant alloys. This document is applicable to aluminium and aluminium alloy wires for the manufacture of concentric lay overhead electrical stranded conductors with or without gap(s) for power transmission purposes.
The various materials and their designations are listed in Table 1. For calculation purposes, the values listed in Table 1 are used.
This first edition cancels and replaces the second edition of IEC 60104 published in 1987, the first edition of IEC 60121 published in 1960, the first edition of IEC 60889 published in 1987, and the first edition of IEC 62004 published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous editions of IEC 60104, IEC 60121, IEC 60889 and IEC 62004:

1. designations of aluminium alloys are modified;
2. aluminium alloys A4, AL4 and AL5 are added;
3. wire diameter ranges for indicating mechanical properties are modified and extended;
4. test methods are merged.
