Overview

IEC 60050-103:2009/AMD4:2021 is the Fourth Amendment to Part 103 of the International Electrotechnical Vocabulary (IEV), focused on Mathematics - Functions. Published by the International Electrotechnical Commission (IEC), this amendment updates precise terminology and definitions related to mathematical functions as applied in electrotechnical fields. It forms an essential reference for professionals and researchers requiring standardized mathematical vocabulary in electrotechnology and related sciences.

This amendment reflects approved changes made by IEC Technical Committee 1 on terminology, ensuring consistency, clarity, and international harmonization of terms used in electrical engineering and applied mathematics. The updated vocabulary supports clear communication and documentation in standards development, technical publications, and professional practice.

Key Topics

• International Electrotechnical Vocabulary (IEV): Mathematics – Functions
  Focuses on defining terms related to mathematical functions as used in electrotechnical contexts, essential for accurate interpretation and application in engineering standards.

• Standing Wave Terminology Update
  Includes revisions such as replacing the definition of "node (of a standing wave)" to clarify terms like standing-wave minimum, nodal line, nodal plane, and nodal surface. Notes emphasize correct usage in acoustics (e.g., particle displacement node, sound pressure node).

• Multilingual Clarity
  Provides definitions and terms in English and French, facilitating international application and comprehension.

• Maintained on Electropedia
  The amendment is integrated into the IEV online platform, ensuring users can access the most current and authoritative electrotechnical vocabulary.

Applications

• Standardization Documentation
  Utilized by standards developers to ensure universally understood terminology when drafting or updating electrotechnical and mathematical standards.

• Research and Development
  Serves as a linguistic and conceptual foundation for R&D teams working on electrotechnical systems requiring rigorous mathematical descriptions.

• Technical Education and Training
  Supports educational institutions by providing standardized definitions that enhance teaching materials in mathematics and electrical engineering.

• Multidisciplinary Engineering Projects
  Facilitates cross-border collaboration by establishing a common vocabulary for mathematical functions and electrotechnical terms, essential for projects involving acoustics, signal processing, and wave phenomena.

Related Standards

• IEC 60050 Series
  The International Electrotechnical Vocabulary is segmented into parts, each addressing different thematic areas. Part 103 specifically covers mathematics in electrotechnical contexts.

• IEC Technical Committee 1 - Terminology
  Oversees the continual maintenance and update of the electrotechnical vocabulary to align with technological advances and terminological precision.

• ICS 01.040.07 and 07.020
  Reflects classification codes aligned with natural and applied sciences, and mathematics, respectively, denoting the document's indexing in international standards repositories.

Why This Matters

Using the updated IEC 60050-103 amendment helps engineers, standardization bodies, and researchers consistently apply terms with agreed meanings, reducing misunderstandings and improving interoperability in electrotechnical systems. Precise function-related vocabulary supports innovation, safety, and efficiency by ensuring that complex mathematical concepts are communicated effectively across diverse technical domains.
