Improvement of the test sample arrangements according to IEC 60243: Electrical strength of insulating materials: test methods

This publication deals with the dielectric breakdown performance of plastics and the problems which occur if the corresponding standard IEC 60243-1 is applied. In the first step, the test materials and the methods were described, followed by the problems, which occur with the specimen according to the standard. In a final step, a solution (specimen) for the problem is developed and evaluated with an exemplary investigation.
