E-3
E.5 Earth Leakage Test
Run an Earth Leakage test on the device being tested before performing any other leakage tests.
The following outlet conditions apply when performing the Earth Leakage test:

normal polarity( Normal Condition),

reverse polarity( Normal Condition),

normal polarity with open neutral(Single Fault Condition),

reverse polarity with open neutral(Single Fault Condition)
LIMITS
For UL60601-1,

300 μA in Normal Condition

1000 μA in Single Fault Condition
For IEC60601-1,

500 μA in Normal Condition

1000 μA in Single Fault Condition
E.6 Patient Leakage Current
Patient leakage currents are measured between a selected applied part and mains earth. All measurements have a true
RMS only
The following outlet conditions apply when performing the Patient Leakage Current test.

normal polarity( Normal Condition);

reverse polarity( Normal Condition),

normal polarity with open neutral(Single Fault Condition);

reverse polarity with open neutral(Single Fault Condition).

normal polarity with open earth(Single Fault Condition);

reverse polarity with open earth(Single Fault Condition).
LIMITS
For CF applied parts

10μA in Normal Condition

50μA in Single Fault Condition
For BF applied parts

100μA in Normal Condition

500μA in Single Fault Condition
