BS EN 60060-3:2006 PDF

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 U m 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.
