The standards making bodies

The structure of the bodies which are responsible for defining EMC standards for the purpose of the EMC directive is shown below.

Plan of IEC61000

IEC 61000-1                      Part 1: General considerations (introduction, fundamental principles, functional safety) Definitions, terminology

IEC 61000-2                      Part 2: Environment Description of the environment Classification of the environment Compatibility levels

IEC 61000-3                       Part 3: Limits Emission limits Immunity limit if not the responsibility of product committees)

IEC 61000-4                      Part 4: Testing and measurement techniques Measurement techniques Testing techniques

IEC 61000-5                      Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices

IEC 61000-6                      Part 6: Generic standards

IEC 61000-9                       Part 9: Miscellaneous (none published to date)

IEC 61000 is published in separate parts by IEC TC77 according to the above plan. Each part is further subdivided into sections which can be published either as international standards or as Technical Reports.

Structure of IEC TC77

TC77 has been characterized as “The United Nations for EMC; certainly it attempts to cover most aspects of the subject on a worldwide basis. The structure of TC77 is shown below It is a large and influential group, and liaises with several other product related committees within IEC including CISPR, there are other outside bodies such as CENELEC, ITU and electric power related groups.

TC77 biggest output is for the various parts of the IEC publication 61000, electromagnetic compatibility.

CISPR

CISPR publications deal with limits and measurements of radio interference characteristics of potentially disturbing sources.  There are a number of sub committees, please refer to table below.
