ASTM D2520 Standard Test for Complex Permeability of Solid Electrical Insulation Materials at Microwave Frequencies and Temperatures Up to 1650 Degrees

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D2520 testing. These test methods cover the determination of the relative complex permittivity (dielectric constant and diffusion factor) of solid non-magnetic dielectric materials.

Test Method A is for samples that are fully formed to the inside dimension of a waveguide.

Test Method B is for specimens of certain geometry that occupies a very small portion of the space in a resonance cavity.

Test Method C uses a resonant cavity with fewer sample size, geometry, and placement restrictions than Test Methods A and B.

Although these methods are used over the microwave frequency spectrum of about 0,5 to 50,0 GHz, each octave increment usually requires a different generator and a smaller test waveguide or resonant cavity.

Testing at high temperatures is done using special high temperature waveguide and resonance cavities.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
