8.2.6 Testing touch current
This test measures current leakage through the exposed conductive parts on the device under
test.
Perform the test in Normal Condition (NC) and in two different Single Fault Conditions (SFC):
1) earth open and 2) one of the supply conductors open at a time. Perform the test with normal
and reverse polarity.
NOTE: Refer to the instructions delivered with the safety analyzer to perform this test.
