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 and ECG leads and e-TRAX Needle Sensor.
Type BF Type BF Applied Part (man in the box) symbol is in accordance with IEC 60417-5333.
e.g., ultrasound probes which are marked with the 'man in box' BF symbol
Type BF
Defibrillator-proof
Type BF defibrillation proof Applied Part (man in the box with paddle) symbol is in
accordance with IEC 60417-5334.
e.g., ECG electrodes which are marked with the 'man in box with paddle' BF symbol
Type CF Type CF Applied Part (heart in the box) symbol is in accordance with IEC 60417-5335.
e.g., 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
Defibrillator-proof
Type CF defibrillation proof Applied Part (heart in the box with paddle) symbol is in
accordance with IEC 60417-5336.
e.g., intraoperative probes for direct cardiac contact, isolated ECG connections and e-TRAX
Needle Sensor, so marked with the 'heart in box with paddle' CF symbol
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.
10.6.3 Outlet Test - Wiring Arrangement - USA & Canada
Test all outlets in the area for proper grounding and wiring arrangement by plugging in the neon outlet tester
and noting the combination of lights that are illuminated. Any problems found should be reported to the
hospital immediately and the receptacle should not be used.
Figure 10-1 Typical Alternate Outlet Tester
1 Correct Wiring 3 Reversed Polarity 5 Hot and Ground Reversed
2 Open Ground Wire 4 Open Neutral Wire 6 Open Hot Wire
Note
No outlet tester can detect the condition where the Neutral (grounded supply) conductor and the Grounding
(protective earth) conductor are reversed. If later tests indicate high leakage currents, this should be
suspected as a possible cause and the outlet wiring should be visually inspected.
