Scope

This part of GB/T 19346 specifies the measurement method for AC magnetic properties of amorphous nanocrystalline alloy coiled ring specimens. This part is suitable for measuring the relative amplitude magnetic permeability, specific total loss and specific apparent power of various transformers and inductance components, as well as amorphous and nanocrystalline soft magnetic alloys for magnetic shielding in the frequency range of 50 Hz to 200 kHz. And other AC magnetic properties. If suitable calibrated instruments are available, the upper frequency limit can be extended to 1 MHz, but in this case the reproducibility requirements should be relaxed appropriately.
