    ASTM D2149

    Significance and Use

    4.1 Permittivity and dissipation factor are sensitive to changes in chemical composition, impurities, and homogeneity. Measurement of these properties is, therefore, useful for quality control and for determining the effect of environments such as moisture, heat, or radiation.

    1. Scope

    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 1In 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.
