*This test takes one minute in Step mode.
**The limit for Protective Earth Resistance is dependent upon the device under test: 0.2
Ω
for devices with a non-detachable power
supply cord; 0.1
Ω
for devices with an appliance inlet.
***Limits for Insulation Resistance are not specified in IEC 601-1.
****Patient Leakage Current, Mains on Applied Part -- Normal Outlet is performed with NORMAL OUTLET polarity and both Normal and
Reversed phase isolated 110% of mains. Patient Leakage Current, Mains on Applied Part -- Reversed Outlet is performed in the same
manner as with a normal outlet except with REVERSE OUTLET polarity.
The limits have been removed for the Enclosure Leakage test with Class IP due to the fact that zero readings are always expected.
Delays are not applied to Class IP sequences.
