3. Test I.P. 3 - Patient Leakage Current: S.F.C.: Mains on Applied Part
• Applicable to internally powered equipment, Types BF and CF.
• Measures the patient leakage current from the Applied Parts to the enclosure caused by the ex-
ternal mains voltage on the Applied Part.
• Maximum auxiliary current Type BF: 500 µA (Range: DC and AC up to 1 kHz).
• Maximum auxiliary current Type CF: 50 µA (Range: DC and AC up to 1 kHz).
4. Test I.P. 4 - Patient Auxiliary Current: Normal Condition
• Applicable to internally powered equipment, Types B, BF and CF.
• Measures the current flowing from one of the Applied Parts and all the others in parallel.
• AP switch is used to obtain all AP combinations.
• Maximum auxiliary current Types B and BF: 10 µA DC; 100 µA (Range: AC 0.1 Hz up to 1
kHz).
• Maximum auxiliary current Type CF: 10 µA (Range: DC and AC up to 1 kHz).
