This part of GB/T 19346 specifies the measurement method for the alternating magnetic properties of amorphous nanocrystalline alloy wound ring specimens.
This part is suitable for measuring a variety of transformer and inductance components and magnetic shielding with amorphous nanocrystalline soft magnetic alloy at 50Hz ~
200kHz frequency range of the relative amplitude of the permeability, than the total loss, compared to the apparent power AC magnetic performance. If there is a suitable calibration
Of the instrument, the frequency upper limit can be extended to 1MHz, but this time the reproduction should be appropriate to relax the requirements.
