Electrical Safety Inspection A-3
A.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.
A.6 Enclosure Leakage Test
The following outlet conditions apply when performing the Enclosure 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);

normal polarity with open earth (Single Fault Condition);

reverse polarity with open earth (Single Fault Condition).

LIMITS
For UL60601-1,

100
μA in Normal Condition.

300
μA in Single Fault Condition.
For IEC60601-1:

100
μA in Normal Condition.

500
μA in Single Fault Condition.
A.7 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).
