E.8 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage using 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) on 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 BF applied parts: 5000 μA.
E.9 Patient Auxiliary Current
Patient Auxiliary currents are measured between any selected Applied Part connector and the
remaining Applied Part connectors. All measurements may have a true RMS response.
The following outlet conditions apply when performing the Patient Auxiliary 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 BF applied parts,
•100 μA in Normal Condition.
•500 μA in Single Fault Condition.
