IEC 60060-1 Ed. 4.0 b:2025

This part of IEC 60060 is applicable to:
– dielectric tests with direct voltage;
– dielectric tests with alternating voltage;
– dielectric tests with impulse voltage;
– dielectric tests with combinations of the above.

This document is applicable to tests on equipment having its highest voltage for equipment Um above 1,0 kV AC and 1,5 kV DC.

NOTE 1 Alternative test procedures can be required to obtain reproducible and significant results. The choice of a suitable test procedure is considered by the relevant Technical Committee.

NOTE 2 For voltages Um above 800 kV it is possible that some specified procedures, tolerances and uncertainties will not be achievable.
