All monitors require the touch leakage tests part 1 and part 2. If the monitor under test
is part of a medical electrical system, such as an EHR, you must also perform “Touch
Leakage, Part 3” on page 2-30 and “Touch Leakage, Part 4” on page 2-30.

Expected Test Results:
Normal condition maximum leakage current x1  100A
This measures leakage current of exposed metal parts of Instrument under Test (IUT)
within the patient environment; normal and reversed polarity using S2.
Safety test according to IEC 60601-1 / ES 60601-1
