Figure 4-20: Example of excessive touch leakage
Measuring principle / limits:
Measurement on a class II appliance (same procedure is used for isolated accessible
conductive parts on class I appliances).
Figure 4-21: Example of excessive touch leakage
Notes:
Each isolated accessible conductive part must be checked separately. The highest
results must be considered.
This is an alternative measurement if insulation and subleakage tests are
questionable.
This is often the only applicable leakage measurement if supply is not allowed to
be interrupted.
If touch leakage currents differ for different appliance operating modes all modes
must be checked. The highest result must be considered!
If the position of line and neutral conductor in the installation or appliance plug is
not predefined, the test must be performed in both directions with higher result
considered.
The measuring instrument must be well grounded during the test.
