sinusoidal waveforms.
The measuring instrument is calibrated by comparing the frequency factor of
with
the solid line in figure F.2 of IEC 60990 at various frequencies. A calibration curve is
constructed showing the deviation of
from the ideal curve as a function of
frequency.
TOUCH CURRENT =
/ 500 (peak value).
The potential at any point (TOUCH CURRENT) expressed as voltage
and
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
and
, does not exceed the
following values:
- for a.c. :
= 35 V (peak) and
= 0.35 V (peak);
- for d.c. :
= 1.0 V
Note:
The limit values of
= 0.35 V (peak) for a.c. and
= 1.0 V for d.c. correspond
to the values 0.7 mA (peak) a.c. and 2.0 mA d.c.
