A-4 Electrical Safety Inspection
 LIMITS
For BF applied parts,
 100μA in Normal Condition.
 500μA in Single Fault Condition.
A.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 BF applied parts: 5000 μA.
A.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 only
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,
 100μA in Normal Condition.
 500μA in Single Fault Condition.
Note:
Make sure the safety analyzer is authorized comply with requirement of IEC60601-1.
Follow the instructions of the analyzer manufacturer.
