- Scope
- This standard specifies the measurement principle and two test methods of AC magnetic properties of amorphous and nanocrystalline soft magnetic alloys - voltammetric phasor method and computer sampling voltammetric method. This standard is suitable for testing the relative elastic permeability, relative viscous permeability and relative amplitude of iron cores of various transformers, inductors and sensors, as well as amorphous and nanocrystalline soft magnetic alloys for magnetic shielding in the frequency range of 50Hz to 1MHz. Magnetic permeability, relative inductance permeability, specific iron loss, excitation power and quality factor and other AC magnetic properties.
