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