3.2.1 Methods of Measurement of Touch-current and Protective
Conductor Current (IEC/TR 60990 (1990-06))
Power supply For simple voltage rated equipment, the rated v a tolerance that
anticipates variances in supply
For rated equipment within the nominal voltage range, the maximum voltage in
the range + a tolerance that anticipates variances in supply
Maximum rated nominal frequency
Point of measurement Between the accessible part (connected to terminal A) and the earth (connected
to terminal B) Between any two accessible parts
Measurement network (1) Measurement network, unweighted touch-current
(2) Measurement network, touch-current weighted for perception/reaction
(3) Measurement network, touch-current weighted for let-go
