IEC 60601-1-2 - RF Conducted Immunity Test Setup - Diagnostic ECG device

Dear all,

I could not find test setup for RF conducted Immunity.


Since, Conducted immunity is about inducing disturbance on ECG cables and checking if the there is any degradation in performance.

Does the setup for the RF radiated immunity (Where ECG DUT is connected to Simulator and CAL waveform is fed) hold good for RF conducted Immunity.

For how much duration does the test run and are we supposed to enable the ECG DUT in continuous data capture mode.

The test setup for conducted immunity can be found in IEC 61000-4-6:2013 clause 7. It is quite different than radiated immunity.

Assuming a 1 second dwell, the test runs for about 10 minutes on each cable tested.

After re-reading you question, the configuration of your equipment would be basically the same.

@Jaydub. Thanks for the reply.
In the case of ECG cables. Do they test all the leads at once or do they test lead by lead.

Subbash,
Do check the latest edition of applicable Particular standards. (-2-25 / -2-27 etc.)
I think you may find that patient leads are not tested for conducted immunity.

Dear @Pads38 ,

I crosschecked with both the standards. Yes, Patient cables are exempt from Conducted disturbances induced by RF Fields and our device does not capture ECG while charging. Hence, we will not be required to do this test.

Thank you.
