Overview
SIST IEC 60050-103:2026/A3:2026 is Amendment 3 to the International Electrotechnical Vocabulary (IEV), specifically Part 103, focusing on Mathematics - Functions. Published by the International Electrotechnical Commission (IEC), this amendment updates terminology related to mathematical functions within the IEV framework. The IEV serves as a crucial global reference for consistent, standardized electrotechnical vocabulary, supporting clear communication and interoperability across industries.
This amendment refines definitions in mathematical functions to support precision in terminology used by engineers, researchers, and educators. It is part of IEC’s ongoing efforts to maintain and enhance the International Electrotechnical Vocabulary, ensuring it remains authoritative and relevant as technologies and scientific understanding evolve.
Key Topics
- Function Terminology Update: Clarifies and replaces existing terminology entries to reflect current conceptual understanding and usage.
- Period Definition (103-06-01): Provides a precise definition for “period” in the context of functions:
Smallest positive difference T between two values of the independent variable t of a function f(t) at which the function's values repeat identically: f(t + T) = f(t).
This formalization helps in consistent usage across disciplines such as signal processing, physics, and control systems. - Bilingual Presentation: Terms and definitions are provided in English and French to support international standardization and accessibility.
- Technical Committee Involvement: Updates are based on change requests approved by IEC Technical Committee 1, responsible for terminology.
Applications
IEC 60050-103 Amendment 3 is essential for professionals and organizations involved in:
- Electrotechnical Engineering: Enhances clarity in describing periodic functions in electrical signals, waveforms, and system behaviors.
- Scientific Research and Education: Provides educators and researchers with precise vocabulary to teach and document mathematical functions clearly.
- Standard Development: Supports the creation and harmonization of other standards where mathematical functions and periodicity are relevant.
- Software and System Design: Assists developers and engineers in implementing and interpreting functions related to time-dependent systems, signal modulation, and waveform analysis.
- International Communication: Harmonizes terms across languages and sectors, enabling better collaboration among international technical communities.
Related Standards
This amendment complements and supports the broader family of IEC standards, including:
- IEC 60050 - International Electrotechnical Vocabulary: The parent standard encompassing all electrotechnical terminology.
- IEC 60050-102 - Mathematics - General concepts: Related mathematical terminology focused on fundamental concepts.
- IEC 60050-104 - Mathematics - Calculus: Related terminology involving differential and integral calculus.
- Other IEC Functional Standards: Where precise mathematical function definitions are critical, such as signal processing or control systems standards.
By aligning with these standards, IEC 60050-103 Amendment 3 ensures a unified and consistent approach to mathematical vocabulary, facilitating accurate communication and effective application across international electrotechnical fields.
