E-3
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
E.7 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage, through a limiting resistance,
to selected applied part terminals. Current measurements are then taken between the selected applied part and earth.
Measurements are taken with the test voltage (110% of mains) to applied parts in the normal and reverse polarity
conditions
The following outlet conditions apply when performing the Mains on Applied Part test.

Normal Polarity

Reversed Polarity
LIMITS
 For CF applied parts: 50 μA
 For BF applied parts: 5000 μA
