This Recommendation applies to the procedures for determination of permittivity and dissipation factor and of quantities calculated from them, such as loss index, within the frequency range 15 Hz to 300 MHz approximately. Some of the methods described in this Recommendation can, with special precautions, be used for measurements at frequencies considerably lower or higher than the given limits. Liquids and fusible materials, as well as solid materials, can be measured by the methods described. The measured values are dependent on physical conditions such as frequency, temperature and moisture content, and in special cases, on field strength as well. In some cases, tests at voltages exceeding 1000 V may introduce effects not related to permittivity and dielectric dissipation factor, and are not described here.
