10. Test P.L.C. 2 - Patient Leakage Current: S.F.C. Open Supply
• Applicable to Classes 1 and 2, Types B, BF and CF.
• Measures patient leakage current to earth from all Applied Parts in parallel with one supply
lead interrupted (S1 = open); normal and reversed polarity using S2.
• Maximum leakage current Types B and BF: 500 µA (Range: DC and AC up to 1 kHz). For
Type CF: 50 µA (Range: DC and AC up to 1 kHz).
11. Test P.L.C. 3 - Patient Leakage Current: S.F.C. Open Earth
• Applicable to Class 1, Types B, BF and CF.
• Measures leakage current to earth from all Applied Parts in parallel with the Protective Earth
open circuit (S4 = open); normal and reversed polarity using S2.
• Maximum leakage current Types B and BF: 500 µA (Range: DC and AC up to 1 kHz). For
Type CF: 50 µA (Range: DC and AC up to 1 kHz).
