TS IEC 60050-103/Amd 2

TS IEC 60050-103/Amd 2 is an amendment to Part 103 of the International Electrotechnical Vocabulary, focused on mathematics and the terminology of functions. As a vocabulary standard, its purpose is to define terms consistently for technical writing and engineering use, rather than to prescribe a test method or a product performance requirement.

What “functions” means in the technical vocabulary context

In general mathematical usage, a function is a rule or mapping that assigns each input from one set to a corresponding value in another set. In electrotechnical work, functions are fundamental to describing signals, time-dependent quantities, system responses, and mathematical models. Clear vocabulary matters because engineering documents often move between abstract notation and physical interpretation.

Why an amendment to a vocabulary standard matters

The value of this document lies in terminology alignment. IEC 60050 vocabulary entries help authors, educators, designers, and standards users apply the same mathematical terms with the same meaning across related technical fields. As an amendment, this record belongs to an update layer on top of the parent part, so it should be understood as part of a controlled terminology framework rather than as a standalone set of operational rules.

For work in electronics, automation, measurement, and control, a well-structured vocabulary reduces ambiguity around terms such as function, relation, domain, argument, and output. That supports clearer specifications, more consistent training material, and better cross-reference between mathematics and engineering practice.
