This is an incomplete list of standards published by the International Electrotechnical Commission (IEC).. The nuers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here.

A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
Air Insulated Switchgear are primary distribution medium voltage switchgears suitable for indoor installations, from Unisun Electric Withdrawable vacuum or gas VCB; IEC 60071-2 for the insulation coordination. IEC 62271-106 for the contactors.
