y application of direct voltage the voltage division across the test specimen is determined by resistance. The choice of direct or alternating voltage depends upon the purpose for which the breakdown test is to be used, and to some extent, on the intended application of the material.
A more complete discussion of the significance of dielectric breakdown tests is given in Appendix X1 of this method and of Test Method D 149. Those appendix sections of Test Method D 149 that refer to alternating vo
