ASTM International Standard Test Method for Permittivity (Dielectric Constant) And Dissipation Factor Of Solid Ceramic Dielectrics At Frequencies To 10 MHz And Temperatures To 500°C ASTM D2149-13

1.1 This test method covers the determination of the relative permittivity (dielectric constant) and dissipation factor of solid dielectrics from 50 Hz to 10 MHz over a range of temperatures from −80 to 500°C.2 ,3 Two procedures are included as follows: 1.1.1 Procedure A-Using Micrometer Electrode. 1.1.2 Procedure B-Using Precision Capacitor. Note 1-In common usage the word “relative” is frequently dropped. 1.2 This standard does not purport to address 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.
