significant.
1. Scope
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 addressed extends from less than 1 Hz to several hundred megahertz.
Note 1In common usage, the word relative is frequently dropped.
1.2 These test methods provide general information on a variety of electrodes
