IEC60364中的2系列和3系列哪里去了

IEC60364是TC64委员会发布的名称为“建筑物的电气装置”的一系列标准。

这本标准目前包含有第一，第四，第五，第六，第七和第八部分，唯独没有第二和第三部分，为什么独独缺少这两部分呢，原来是最早的时候是有二部分和三部分的，但是没有后面的678部分的。我们从最早版本的iec60364可以看出端倪

IEC 60364-1:1970
Electrical installations of buildings - Part 1: General and definitions
IEC 60364-2:1993
Electrical Installations of Buildings Part 2: Definition
Superseded By: IEC 60364-1

IEC 60364-3:1973
Electrical installations of buildings - Part 3: General requirements for installations
Partly superseded by IEC 60364-3 and IEC 60364-4-41.

IEC 60364-4:1977
Electrical installations of buildings. Part 4: Protection for safety

IEC 60364-5:1993
Electrical installations of buildings - Part 5: Selection and erection of electrical equipment

IEC 60364-6:2006
Low-voltage electrical installations - Part 6: Verification

IEC 60364-7:2002
Electrical installations of buildings - Part 7: Requirements for special installations or locations

IEC 60364-8:2014
Low-voltage electrical installations - Part 8: Energy efficiency

从中能看出不但IEC的编号在重整，而且这个系列的名称也进行了变更，从最开始的“Electrical installations of buildings”到现在的"Low-voltage electrical installations",也即从建筑物电气装置到低压电气装置，扩充了范围。

目前这个现行系列是这样的：
