10-7-3 Leakage Current Limits (cont’d)
NOTE: Leakage current limits for Ultrasound system operation on 230-240 Volt mains
*ISO and Mains Applied (On a calibrated Electrical Safety Analyzer compliant with AAMI/ESI 1993 or
IEC 60601 or AS/NZS 3551.) refer to the sink leakage test where mains (supply) voltage is applied to
the part to determine the amount of current that will pass (or sink) to ground if a patient contacted mains
voltage.
Table 10-11 ISO and Mains Applied (On a calibrated Electrical Safety Analyzer compliant with
AAMI/ESI 1993 or IEC 60601 or AS/NZS 3551.) Limits*
Probe Type Measurement
BF 5.0 mA (5000 µA)
CF 0.05 mA (50 µA)
Table 10-12 Equipment Type and Test Definitions
Applied Parts
(AP)
Parts or accessories that contact the patient to perform their function. For ultrasound
equipment, this includes transducers, ECG leads and e-TRAX Needle Sensor.
Type BF
Body Floating or non-conductive ultrasound
probes which are marked with the 'man in box'
BF symbol. this includes all transducers and
ECG leads
or
Type CF
Cardiac Floating or non-conductive,
intraoperative probes for direct cardiac contact,
isolated ECG connections and e-TRAX Needle
Sensor which are marked with the 'heart in box'
CF symbol.
or
Sink
Leakage
The current resulting from the application of mains voltage to the applied part. This test
is required test for Type CF applied parts.
