10-7-2 Leakage current limits(continued)
NOTE: *Mains Applied refers 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.
The following tests are performed at the factory and should be
performed at the site. These tests are: chassis leakage current,
and probe leakage current. All measurements are made with an
electrical safety analyzer which should be calibrated and
compliant with AAMI/ESI 1993 or IEC 60601 or AS/NZS 3551.

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.
