Abstract
The ac/dc magnetic-flux-density (MFD) standard systems were developed for the calibration of magnetometers and the test of sensors and materials. The dc MFD is maintained to cover the range from 20 μT to 2.5 T with the expanded uncertainties (k = 2) from 4 μT/T to 80 μT/T. The expanded uncertainty (k = 2) of ac MFD standard is 0.2 % in the range of 1 Hz to 20 kHz. We had been participated in international key comparison to achieve the equality and the mutual agreement between standard institutes for the results of calibrations and tests.
