IEC 60906-2:20 11适用于额定为15 A 125 V交流电的插头和插座的IEC系统。和20A 125V交流电。用于家用和类似用途，用于将设备连接到标称电压在100 V和130 V交流电之间的配电系统。就尺寸要求而言。本IEC 60906-2第三版取消并取代1997年出版的第二版，构成技术修订。较上一版主要变化如下: -修改槽尺寸的公差； -结合较短的最大叶片长度； -限定电触头的凹部的新尺寸； -用于检查的新量具，以验证尺寸是否符合部分插入和拔出插头刀片期间的电击保护。

IEC 60906-2:2011 applies to the IEC system of plugs and socket-outlets rated 15 A 125 V a.c. and 20 A 125 V a.c. for household and similar purposes, for the connection of equipment to distribution systems having nominal voltages between 100 V and 130 V a.c. in so far as dimensional requirements are concerned. This third edition of IEC 60906-2 cancels and replaces the second edition published in 1997, and constitutes a technical revision. The main changes from the previous edition are as follows:
- revision to tolerances on the slot dimensions;
- incorporate a shorter maximum length of blade;
- new dimensions to define the recess of electrical contacts;
- new gage for inspection to verify dimensional compliance to protection from electrical shock during partial insertion and withdrawal of plug blades.
