Title
Standard Test Method for Permittivity (Dielectric Constant) and Dissipation Factor of Solid Dielectrics at Frequencies to 10 MHz and Temperatures to 500 Degrees C
ASTM International
Publication Date:
Sep 10, 1997
Scope:
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.(Footnote 2,3) Two procedures are included as
follows:
Procedure A - Using Micrometer Electrode.
Procedure B - Using Precision Capacitor.
NOTE 1 - In common usage the word "relative" is frequently dropped.
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.
