IEC TC 1 and the International Electrotechnical Vocabulary

15 June 2017

Terminology plays a key role in ensuring that a message understood is identical to the message that is being communicated. Therefore it is no accident that the first technical committee established in 1911 by the IEC was TC 1: Terminology.

The scope of TC 1 is to oversee the development and permanent maintenance of the IEC 60050 series of Standards, the totality of which constitutes the International Electrotechnical Vocabulary (IEV) [the online version of which is called the Electropedia].

The primary goal of the IEV is the standardization of the terms and definitions needed by standards’ writers to prepare IEC Standards, and standards’ users to understand and implement them. The IEV is also intended to be of use to translators of technical texts, in technical specifications and in commercial exchanges.

TC 1 develops and maintains the “general concepts” parts of the IEV, and is responsible to work with the other IEC committees to integrate their terms and definitions that fall within the scope in the IEV. In this way, TC 1 acts as the custodian of the IEV to ensure:

  • that the IEV entries are consistent with each other, to the greatest extent possible
  • that different concepts are identified by distinct terms
  • and that the structural principles on which the IEV is based and other rules specified in the IEC Supplement to the ISO/IEC Directives, Annex SK, are respected

TC 1 works in close collaboration with the IEC Terminology Coordinator to support and coordinate IEC activities relating to terminology.

We can be proud of the fact that today's IEV is the result of the collaborative work of IEC experts over a period of more than 100 years. Let's work together to make the next 100 years even better!
