Resistance values in orms ( ).

V: Voltmeter or oscilloscope

(r.m.s. or peak reading)

Input resistance :

Input capacitance :

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

TOUCH CURRENT =

The potential at any point (TOUCH CURRENT) expressed as voltage

does not exceed the following value:

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.

The TOUCH CURRENT expressed as voltages

following values:

- for a.c. :

- for d.c. :

Note: The limit values of

the values 0.7 mA (peak) a.c. and 2.0 mA d.c.
