Overview

EN 10252:1997 (CEN) - Magnetic materials - Methods of measurement of magnetic properties of magnetic steel sheet and strip at medium frequencies - defines terminology and specifies methods for measuring magnetic properties of magnetic steel sheet and strip used to build magnetic circuits. The standard applies to materials and testing in the medium-frequency range (400 Hz to 10 000 Hz) and is intended for consistent, reproducible measurement of the magnetic characteristics that affect electromagnetic device performance.

Key Topics

• Scope and applicability: magnetic steel sheet and strip for magnetic circuits operating between 400 Hz and 10 kHz.
• Terminology: standardized definitions for magnetic terms used in measurement and reporting to ensure clarity across manufacturers, test labs, and designers.
• Measurement methods: specified approaches for determining magnetic properties of sheet and strip materials at medium frequencies (methods are described so results are comparable between laboratories and suppliers).
• Specimen handling and preparation: guidance on test samples and conditions to reduce variability and ensure meaningful comparisons.
• Accuracy and reproducibility: emphasis on repeatable test procedures and reporting formats to support quality control and material acceptance.

(EN 10252:1997 focuses on establishing common measurement practices rather than prescribing material compositions or performance limits.)

Applications

• Manufacturers of magnetic steel sheet and strip use the standard for product characterization and quality control.
• Test laboratories and QA/QA departments apply the measurement methods to certify material performance at medium frequencies.
• Designers and engineers of magnetic circuits - including transformers, inductors, motors, actuators, and power electronics components operating in the 400 Hz–10 kHz range - rely on standardized magnetic property data (e.g., permeability, losses, magnetization behavior) to model and optimize devices.
• R&D teams use the standard to compare material options and to validate improvements in magnetic performance for medium-frequency applications.

Related Standards

• Works alongside other national and international standards on magnetic materials, test methods and electromagnetic component specification. Users often consult complementary CEN/ISO/IEC standards for low-frequency or high-frequency testing, material composition, and core-loss measurement practices.

EN 10252:1997 is a practical reference for anyone needing consistent, comparable measurements of magnetic steel sheet and strip properties at medium frequencies. Keywords: EN 10252:1997, magnetic materials, magnetic steel sheet, magnetic strip, medium frequencies, magnetic properties measurement, CEN, magnetic circuits, 400 Hz–10 kHz.
