1 Scope
This part of IEC 60060 is applicable to the following on-site test voltages and in service stresses, which
are in relation to IEC 60060‑1:
-
– direct voltage;
-
– alternating voltage;
-
– lightning impulse voltage of aperiodic or oscillating shape;
-
– switching impulse voltage of aperiodic or oscillating shape.
For special tests the following voltages are used:
-
– very low frequency voltage;
-
– damped alternating voltage.
This standard is applicable to equipment with a highest voltage Um greater than 1 kV. The selection of on-site test voltages, test procedures and test
voltage levels for apparatus, equipment or installations is under the responsibility
of the relevant technical committee.
For special applications, on-site test voltages different from those described in
this standard may be specified by the relevant technical committee.
NOTE 1 The different voltage waveforms listed above do not necessarily provide equal stress on the test object.
NOTE 2 The selection of the test voltage levels should take the larger tolerances and measuring uncertainties into account.
