This standard specifies the measurement methods of inductance factor, quality factor, parallel inductance factor and parallel resistance coefficient of double-hole and porous magnetic cores made of magnetic oxides. This standard applies to magnetic oxide double-hole and porous cores used as branches, distributors, baluns and other wide-band transmission transformers. The effective peak magnetic flux density of the magnetic core is less than 5mT.
