Leakage Current Limits - GE Voluson E Series Service Manual

10.6.2 Leakage Current Limits

The following acceptance limits and test conditions are summarized from IEC 60601 including national
deviations and IEC 62353 and in some cases are lower than that specified by the standards.
Leakage Current Test
Earth Leakage
Chassis/Enclosure Leakage
Type BF Applied Parts
Type CF Applied Parts
Type BF Applied Parts (sink leakage,
mains voltage on applied part)
Type CF Applied Parts (sink leakage,
mains voltage on applied part)
Values based on IEC 60601
Open Grounding is also known as "Lift Ground".
Note
* ISO and Mains Applied refers to the sink leakage test where mains (supply) voltage is applied to the
applied part to determine the amount of current that will pass (or sink) to ground if a patient is in contact with
mains voltage.
Electrical leakage testing may be accomplished with any calibrated Electrical Safety Analyzer tool compliant
Note
with AAMI/ESI 1993 or IEC 60601 or AS/NZS 3551 or IEC 62353 or other relevant national regulation.
