TS IEC 60050-131/A1

TS IEC 60050-131/A1 is an amendment to Part 131 of the International Electrotechnical Vocabulary, the part devoted to circuit theory. It addresses the general terminology used in electric and magnetic circuit theory, including terms for circuit elements and their characteristics, network topology, n-port and two-port networks, and methods of circuit theory.

As a terminology document, its value lies in keeping technical language consistent across the field. Core concepts such as resistance, capacitance, impedance, conductance, network structure, and circuit-analysis approaches are used together in many branches of electrical engineering. This part is positioned to remain consistent with the other specialized sections of the IEV, helping related disciplines use the same technical terms without contradiction.

Main terminology areas covered by the circuit-theory part

• General terms for electric and magnetic circuits
• Circuit elements and their characteristics
• Network topology and interconnection structures
• N-port and two-port networks
• Methods of circuit theory

This listing is an amendment, so it represents an update or supplementation linked to the base vocabulary part rather than a standalone full rewrite of the subject. The scope also notes that the material on polyphase circuits from the first edition of “Electric and magnetic circuits” is to be developed in a separate part of IEC 60050. In practical use, this means the document belongs to the broader controlled vocabulary for circuit theory and related electrotechnical language.
