impulse testing. Thus, the impulse test gives values closer to the intrinsic breakdown strength than do longer time tests. From comparisons of the impulse dielectric strength with the values obtained from longer time tests, inferences may be drawn as to the modes of failures under the various tests for a given material. Appendix X1 of Test Method D 149 should be referred to for further information on this subject.
