Pete (or anyone on the list), do you know of a human body circuit model
that is above 1 MHz? The circuits that are talked about below only go to a
megahertz.

Mike,

            The Touch Current test circuits are taken directly from IEC
60990 (Measurement of Touch Current and Protective Conductor Current).

            A collection of Touch Current measurements measured with the
circuit that includes the frequency compensation network shown in these
standards (called the Perception-Reaction network) can be found at
www.safetylink.com by searching on perkins.

      Can anyone tell me if the touch test circuits of 60950 and 60065 are
      the same?
