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
