Overview

EN IEC 60404-6:2018/A1:2021 (IEC 60404-6:2018/AMD1:2021) is an amendment to the international standard for measuring AC magnetic properties of magnetically soft metallic and powder materials using ring specimens. The amendment (A1, approved August 2021) refines the original scope so the standard applies to soft magnetic materials (excluding soft ferrites) over the frequency range 20 Hz to 100 kHz. It is published by CENELEC / IEC and adopted nationally (e.g., SIST EN IEC 60404-6:2018/A1:2021).

Key Topics

• Measurement methods: Defines standardized procedures for determining AC magnetic properties of magnetically soft metallic and powder materials using toroidal (ring) specimens.
• Frequency range: Tests and characterization are defined for 20 Hz to 100 kHz, covering power-frequency to high-frequency applications.
• Material scope: Targets magnetically soft metallic and powder materials; the amendment explicitly excludes soft ferrites.
• Specimen geometry: Uses ring (toroidal) specimens to minimize demagnetizing effects and provide reproducible results.
• Standardization and compliance: Aligns with IEC/ISO directives and CENELEC adoption rules; includes references to normative documents and considerations about patent rights.

(Note: this summary highlights the standard’s focus - for detailed test procedures, instrumentation, and data presentation see the full standard text.)

Applications

EN IEC 60404-6:2018/A1:2021 is directly applicable where reliable, comparable AC magnetic property data are required:

• Material producers validating soft magnetic metallic and powder products (e.g., grain-oriented and non-oriented steels, amorphous and nanocrystalline ribbons, soft magnetic powders).
• Test and calibration laboratories performing standardized permeability, core loss, and magnetization measurements using ring specimens.
• Electrical and electronic designers for transformers, inductors, motors, actuators and power electronics where AC magnetic response across 20 Hz–100 kHz affects performance.
• R&D teams and academic research needing standardized measurement data to compare materials or validate models.

Who Should Use It

• Manufacturers of soft magnetic materials and components
• Accredited testing laboratories and quality control engineers
• Electromagnetic design engineers and product development teams
• Standards committees and procurement specialists specifying material test requirements

Related Standards

• Other parts of the IEC 60404 series (Magnetic materials) for additional measurement methods and material classes.
• National adoptions such as SIST EN IEC 60404-6:2018/A1:2021 reflect the same technical content at regional level.
