A.3 Tests on Internally Powered Equipment According To IEC 601.1/UL 2601.1
1. Test I.P. 1 - Enclosure Leakage Current: Normal Condition
• Applicable to internally powered equipment, Types B, BF and CF.
• Measures leakage current of the exposed metal parts of the instrument under test.
• For Type BF and CF equipments, measures with the AP/GND switch S3 open and closed.
• Maximum leakage current: 100 µA (Range: DC and AC up to 1 kHz).
2. Test I.P. 2 - Patient Leakage Current: Normal Condition
• Applicable to internally powered equipment, Types B, BF and CF.
• Measures the patient leakage current from the Applied Parts to the enclosure.
• For Type BF and CF equipments, measures with the AP/GND switch S3 open and closed.
• Maximum auxiliary current Types B and BF: 100 µA (Range: DC and AC up to 1 kHz). For
Type CF: 10 µA (Range: DC and AC up to 1 kHz).
