So have we but there is no official method that would have everyone conform
to the same method.

AM RE: Contact Currents
Unfortunately there is no standard that tells you how to measure contact
currents above 1 MHz.
Hmmm...
If I have a small inductor less resistor in series with the RF supply and I
measure the voltage across the resistor and divide by the resistance -
maybe that would do?
I am sure I have measured pulses in EMC tests that use an inductor less 0.1
Ω resistor and the pulses have fast rise-times with many 10's MHz bandwidth
or even more.
I have not measured contact currents in this way but I suspect it will give
a pretty good approximation.
Any other takers?
Tim
