„ 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 μ A in Normal Condition
„ 50 μ A in Single Fault Condition
For BF applied parts
„ 100 μ A in Normal Condition
„ 500 μ A in Single Fault Condition
B.8 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 μ A
„ For BF applied parts: 5000 μ A
B.9 Patient Auxiliary Current
Patient Auxiliary currents are measured between any selected Applied Part connector and the
remaining Applied Part connector. All measurements may have a true RMS only response.
The following outlet conditions apply when performing the Patient Auxiliary Current test.
