This standard specifies: amorphous and nanocrystalline soft magnetic alloy AC magnetic measuring principle and two test methods Phasor CV and computer sampling voltammetry. This standard applies to: Test a variety of transformers, inductors, and sensors with core and magnetic shielding amorphous and nanocrystalline soft magnetic alloy in 50Hz ~ 1MHz frequency range relatively resilient permeability, relatively viscous permeability, relative width value of the permeability, relative permeability inductance, AC magnetic properties of iron loss ratio, excitation power and quality factor and so on.
