Sets out the method for determining the dielectric breakdown voltage at power frequency, of insulating liquids of nominal viscosity up to 350 mm(sup)2(/sup)s(sup)-1(/sup) at 40°C. Intended for use of acceptance testing on new liquids and for monitoring the condition of liquids in use. This Standard is identical with and has been reproduced from IEC 60156:1995.

Scope

This international Standard specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency. The test portion, contained in a specified apparatus, is subjected to an increasing a.c. electrical field by means of a constant rate of voltage rise until breakdown occurs.
The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2s-1at
40 ¦C. It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment.
