Applies to the determination of relative permittivity and dielectric dissipation factor of solid and liquid or fusible dielectric materials in the microwave frequency by resonance methods. Covers test apparatus, test specimens, testing procedures and the evaluation of measured data. The appendix gives details of various types of resonator.
