"NettetUsing the NACE formula the test voltage is: We know the dielectric strength is 8400 V /mm so for 2mm the maximum voltage before breakdown occurs is 2 x 8400 = 16,800 V. In this example then the test voltage of 11,180 V can be used since it is less than the breakdown voltage of the material (16,800V). " - Holiday test standard
