1.1 These test methods cover the determination of relative permittivity, dissipation factor, loss index, power factor, phase angle, and loss angle of specimens of solid electrical insulating materials when the standards used are lumped impedances. The frequency range that can be covered extends from less than 1 Hz to several hundred megahertz.Note 1-In common usage, the word relative is frequently dropped.
1.2 Since some materials require special treatment, the reader may also wish to consult other ASTM standards or documents directly applicable to the material to be tested.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 188.8.131.52 and 9.2.1.
