Leakage Current Limits
The following acceptance limits and test conditions are summarized from IEC60601 including national
deviations and IEC 62353 and in some cases are lower than that specified by the standards. In
accordance with these standards, fault conditions like Reverse Polarity of the supply mains and Open
Neutral are no longer required for field evaluation of leakage current. Because the main source of
leakage current is the mains supply, there are different acceptance limits depending on the
configuration of the mains (100-120VAC or 230-240VAC).
*
ISO
(on Dale 600) and
Mains Applied
(on Dale 601) 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.
