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
For BF
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.
