ASTM D3755-97

1.1 This test method covers the determination of dielectric breakdown voltage and dielectric strength of solid electrical insulating materials under direct-voltage stress.

1.2 Since some materials require special treatment, reference should also be made to ASTM specifications or to the test method directly applicable to the material to be tested. See Test Method D 149 for the determination of dielectric strength of electrical insulating materials at commercial power frequencies.
