IEC specifications MV switchgear maintenance

This is an incomplete list of standards published by the International Electrotechnical Commission (IEC).. The numbers 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.
