TS IEC 60050-300/A1

TS IEC 60050-300/A1 is an amendment to the International Electrotechnical Vocabulary focused on the general terms used in electrical and electronic measurements. As a vocabulary document, it supports a common technical language for metrology, instrument design, testing, and laboratory work, helping users apply the same concepts consistently across documentation and practice.

The role of electrical measurement terminology

Electrical measurements cover a broad field that includes quantities such as voltage, current, resistance, power, and energy, together with the concepts used to describe how these quantities are measured. In general technical use, terms such as measurand, measurement principle, indication, error, and uncertainty are central to comparing results and communicating them clearly. A controlled vocabulary is especially important where instruments, test methods, and technical documents must remain consistent across organizations and languages.

What an amendment contributes

As an amendment, this record is an official update to the parent vocabulary rather than a standalone measurement method or test standard. Its value lies in refining, correcting, or aligning terminology so that the underlying concepts remain coherent in professional use. That makes it relevant to metrology, electrical test engineering, instrument documentation, and any context where precise term usage matters.

• Connected to IEV Part 300 terminology for electrical and electronic measurements.
• Covers general terms that structure common measurement language.
• As an amendment, it updates or complements the vocabulary framework of the base publication.
• Useful as a reference for laboratories, instrument manufacturers, and technical documentation.
