D-4 Electrical Safety Inspection
„
LIMITS
For BF applied parts
z
100 μ A in Normal Condition
z
500 μ A in Single Fault Condition
D.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.
z
Normal Polarity;
z Reversed Polarity
„ LIMITS
z
For BF applied parts: 5000 μ A
D.9 Patient Auxiliary Current
Patient Auxiliary currents are measured between any selected Applied Part connector and
the remaining Applied Part connector s. All measurements may have a true RMS only
response.
The following outlet conditions apply when performing the Patient Auxiliary Current test.
z
normal polarity( Normal Condition);
z
reverse polarity( Normal Condition),
z
normal polarity with open neutral(Single Fault Condition);
z reverse polarity with open neutral(Single Fault Condition).
z
normal polarity with open earth(Single Fault Condition);
z
reverse polarity with open earth(Single Fault Condition).
„ LIMITS
For BF applied parts,
z
100 μ A in Normal Condition
z
500 μ A 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.
