TS IEC 60050-101

TS IEC 60050-101 is the mathematics part of the International Electrotechnical Vocabulary and organises terms from selected fields of mathematics that are especially useful within the IEV. The treatment is not purely mathematical in every case; depending on the topic, it may adopt either a mathematical or a physical point of view. Its role is to support consistent technical terminology rather than to function as a full mathematics textbook.

How the terms are intended to be used

The definitions in this part are not meant to be complete mathematical definitions in the strict academic sense. They are provided for identification and terminology, which is an important distinction in vocabulary standards. In practice, that means the standard helps users in electrical engineering, measurement, physics, and related fields communicate with shared conceptual precision. Letter symbols and mathematical signs are included for information only, so the focus is on concepts and naming rather than on prescribing notation in detail.

General technical context

Mathematics underpins the expression of quantities, relationships, and models in electrotechnics and engineering more broadly. Clear terminology matters when concepts such as functions, operations, relations, and representations are used across disciplines. The linked international standards IEC 60027 and ISO 31 provide the broader standardisation context for symbols and quantities, helping align vocabulary with established notation practice.

• Part 101 focuses on selected areas of mathematics that are useful for the IEV.
• Its definitions are intended for terminology and identification, not as complete formal mathematical definitions.
• The perspective may be mathematical or physical, depending on the subject.
• Letter symbols and mathematical signs are given for information only.
• The relevant international standards identified are IEC 60027 and ISO 31.
