Dear Forum Experts,
For IEC 60601, at 8.7 Leakage currents and patient auxiliary current, it states the following requirement:
8.7.1 General requirements
(b) The specified values of the Earth Leakage Current, the Touch current, the Patient Leakage Current and the Patient Auxiliary current apply in any combination of the following conditions:
- at operating temperature and following the humidity preconditioning treatment, as described in 5.7;
- in Normal Condition and in the Single Fault Conditions specified in 8.7.2;
- with ME Equipment energized in stand-by condition and fully operating and with any switch in the Mains Part in any position;
- with the highest Rated supply frequency;
- with a supply equal to 110% of the highest Rated Mains Voltages
What does that actually means? Does it really mean that I only have to test "any combination" or "all combination"?
Thanks,
C.
