IEC 61000: Electromagnetic Compatibility (EMC) is the counterpart of the IEEE Power Quality Standards. Please take note that the IEC does not yet use the term power quality in any of its standard documents. Instead the IEC uses the term electromagnetic compatibility, which is not the same as power quality but there is a strong overlap between the two terms. IEC 61000: Electromagnetic Compatibility (EMC) Standard consists of six parts, each consisting of several sections. Listed below are brief descriptions of IEC Standard sections that are related to power quality.
