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
◆
10 μA in Normal Condition
◆
50 μA in Single Fault Condition
For BF
applied parts
◆
100 μA in Normal Condition
◆
500 μA 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
