Arc resistance
The aim of this test method is to make a relative distinction between solid electrical insulating materials. Their ability to resist an arc at a high voltage but with a weak current in the vicinity of the insulating surface is investigated.

Result of the test method:

The time until the arc is no longer generated due to the formation of conductive tracking.
