10-6-2 Leakage Current Limits (cont’d)
* ISO and Mains Applied 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.
NOTE: Electrical leakage testing may be accomplished with any calibrated Electrical Safety Analyzer
tool compliant with AAMI/ESI 1993 or IEC 60601 or AS/NZS 3551.

Table 10-11 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 and ECG leads.
Type BF
Body Floating or non-conductive ultrasound probes
which are marked with the 'man in box' BF symbol.
This includes all transducers.
Type CF
Cardiac Floating or non-conductive intraoperative
probes for direct cardiac contact and isolated ECG
connections so marked with the 'heart in box' CF
symbol.
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.
