IEC 62810:2015 PDF

Scope: This International Standard relates to a measurement method for complex permittivity of a dielectric rod at microwave frequency. This method has been developed to evaluate the dielectric properties of low-loss materials in coaxial cables and electronic devices used in microwave systems. It uses the TM010 mode in a circular cylindrical cavity and presents accurate measurement results of a dielectric rod sample@ where the effect of sample insertion holes is taken into account accurately on the basis of the rigorous electromagnetic analysis. In comparison with the conventional method described in IEC 60556 [2]1@ this method has the following characteristics: the values of the relative permittivity ?? and loss tangent tan ??of a dielectric rod sample can be measured accurately and non-destructively; the measurement accuracy is within 1@0 % for ??' and within 20 % for tan ?? the effect of sample insertion holes is corrected using correction charts presented;
