Overview
IEC 60050-221:1990/AMD2:1999 is Amendment 2 to the International Electrotechnical Vocabulary (IEV), specifically Part 221, which focuses on Magnetic Materials and Components. This amendment, published by the International Electrotechnical Commission (IEC), provides refined and additional terminology related to magnetic materials such as alloys, steels, ferrite materials, and magnetic components. It aims to standardize definitions and terms in the field of electrotechnology for consistent international communication and application.
Prepared by IEC Technical Committee 68 (Magnetic alloys and steels) in cooperation with Technical Committee 51 (Magnetic components and ferrite materials) under the responsibility of Technical Committee 1 (Terminology), this amendment enhances clarity in magnetic material properties and related phenomena such as temperature coefficients and losses under rotating magnetic fields.
Key Topics
This amendment introduces and refines several important technical terms:
Temperature Coefficient of Saturation Magnetization (αMs)
Represents the relative change in saturation magnetization of a magnetic material per unit change in temperature. It is a key parameter for understanding temperature effects on magnetic performance.Temperature Coefficient of Saturation Magnetic Polarization (αJs)
Defines the relative variation of magnetic polarization at saturation with respect to changes in temperature. Critical for precise modeling of magnetic behavior in varying thermal environments.Rotational Hysteresis Loss
Describes the power absorbed due to magnetic hysteresis when a material is subjected to a magnetic field whose direction rotates within a plane. This loss impacts efficiency in rotating magnetic device applications.Rotational Power Loss
Total power loss absorbed when a magnetic material experiences a rotating magnetic field, combining hysteresis and other loss mechanisms relevant to dynamic magnetic applications.
The amendment also corrects and supplements previous entries to ensure technical accuracy and comprehensive international terminology coverage. It provides definitions in multiple languages, supporting global usability.
Applications
IEC 60050-221 Amendment 2 is essential for professionals and industries working with magnetic materials and components, including:
Electromagnetic Device Design
Engineers designing transformers, inductors, electric motors, and magnetic sensors rely on standardized terms related to temperature coefficients and loss mechanisms to optimize performance.Material Science and Development
Researchers developing new magnetic alloys or ferrites use the vocabulary to characterize material behavior under different thermal and magnetic conditions consistently.Energy Efficiency Analysis
Understanding rotational hysteresis and total rotational power losses supports the design of energy-efficient rotating machines and power conversion systems.Quality Control and Testing
Standardized definitions aid in specifying measurement methods and performance criteria for magnetic components subject to varying temperature and dynamic magnetic fields.International Trade and Documentation
Harmonized terminology facilitates clear communication among manufacturers, testing laboratories, and clients worldwide.
Related Standards
For comprehensive understanding and application, IEC 60050-221 Amendment 2 should be used in conjunction with related IEC and international standards such as:
- IEC 60050 - International Electrotechnical Vocabulary (IEV) – The broader series covering electrotechnical terms beyond magnetic materials.
- IEC TC 68 Standards on Magnetic Materials – Covering properties, testing methods, and specifications of magnetic alloys and steels.
- IEC TC 51 Standards on Magnetic Components and Ferrites – Offering detailed guidance on ferrite materials and magnetic component specifications.
- IEC 60404 Series – Pertaining to magnetic materials characterization.
- ISO/IEC Directives – For terminology management and standardization processes.
Adhering to this amendment supports industry best practices, enhances clarity in documentation, and promotes innovation in magnetic material technologies worldwide.
