E.6 Patient Leakage Current
Patient leakage currents are measured between a selected applied part and mains earth. All measurements have
a true RMS only
The following outlet conditions apply when performing the Patient Leakage 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 CF applied parts
◆ 10 A in Normal Condition
◆ 50 A in Single Fault Condition
For BF applied parts
◆ 100 A in Normal Condition
◆ 500 A in Single Fault Condition
E.7 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 A
◆ For BF applied parts: 5000 A
