Magnetic materials. Part 2 : Methods of measurement of magnetic, electrical and physical properties of magnetic sheet and strip

This technical specification establishes a unified framework for evaluating the magnetic, electrical, and physical characteristics of soft magnetic materials, specifically focusing on steel sheets and strips. The document outlines standardized procedures required to ensure consistency and accuracy when measuring properties such as permeability, coercivity, core loss, and dimensional stability. By defining precise experimental conditions, sample preparation methods, and measurement equipment requirements, it facilitates reliable comparisons across different manufacturing batches and global laboratories. The guidelines address the influence of factors like frequency, magnetic induction levels, and temperature on performance metrics. Adherence to these protocols allows industry stakeholders to verify material quality against established benchmarks without ambiguity. The approach ensures that data generated during testing is reproducible and comparable, supporting the development of efficient electromagnetic devices. This methodology remains a foundational reference for characterizing magnetically soft alloys used in transformers, motors, and inductors.
