10-18 Section 10-3 - Why Perform Maintenance Procedures?
PRELIMINARY
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 10-13 ISO and Mains Applied Limits
a
Probe Type Measurement
BF 5.0 mA (5000 µA)
CF 0.05 mA (50 µlA)
a. ISO and 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 is in
contact with mains voltage
Table 10-14 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.
Type BF
Defib.-Proof
Type BF Applied Part (man in the box
with paddle) symbol is in accordance
with IEC 60417-5334.
Type CF Cardiac Floating or non-conductive
intraoperative probes for direct cardiac
contact, isolated ECG connections and
e-TRAX Needle Sensor, so marked with
the 'heart in box' CF symbol.
Type CF
Defib.-Proof
Applied Part (heart in the box with
paddle) symbol is in accordance with
IEC 60878-02-06.
Sink
Leakage
The current resulting from the application of mains voltage to the
applied part. This test is required for Type BF and CF applied parts.
