Applies 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.

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.
