Frequency range : 15 Hz to 1 MHz and d.c. respectively
Note: Appropriate measures should be taken to obtain the correct value in case of non
sinusoidal waveforms.
The measuring instrument is calibrated by comparing the frequency factor of
solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is
constructed showing the deviation of

The part or contact of a TERMINAL is not HAZARDOUS LIVE if:
a) The open-circuit voltage should not exceed 35 V (peak) a.c. or 60 V d.c. or, if a) is not
met.
b) The measurement of the TOUCH CURRENT shall be carried out in accordance with
IEC 60990, with the measuring network described in Annex D of this standard.
