TS IEC 60050-111

TS IEC 60050-111 is the chapter of the International Electrotechnical Vocabulary devoted to physics and chemistry, bringing together the general terms and definitions used in these fields. In electrotechnical work and related scientific practice, a shared meaning for concepts is important for understanding measurement, material behaviour, energy, matter, and other fundamental physical quantities.

The role of physics and chemistry terminology in the vocabulary

This chapter organises core concepts that are widely used in technical contexts even when they are not strictly electrical in nature. Physics provides the general language of motion, force, energy, heat, light, and electricity, while chemistry supplies the terminology for the composition, structure, reactions, and properties of matter. Keeping these concepts clearly separated and consistently defined helps technical documents use scientific language in a precise and interoperable way.

What this standard provides

• General terms and definitions from physics and chemistry
• Conceptual organisation aligned with the International Electrotechnical Vocabulary structure
• A common reference layer for scientific language used in electrotechnical disciplines
• A chapter linked to IEC 60050-111 and IEC 60050-111/AMD 1

In general technical use, a vocabulary standard like this helps align terminology across standards, specifications, training materials, and engineering documentation. It reduces ambiguity when the same word could be interpreted differently across disciplines or organisations. TS IEC 60050-111 therefore serves as a structured reference for using physics and chemistry concepts in a consistent and internationally recognisable way.
