ASTM D149 -
National Technical Systems
This test method covers procedures for the determination of dielectric strength of solid insulating materials at commercial power frequencies, under specified conditions. Unless otherwise specified, the tests shall be made at 60 Hz. However, this test method is suitable for use at any frequency from 25 to 800 Hz. At frequencies above 800 Hz, dielectric heating is a potential problem. This test method is intended to be used in conjunction with any ASTM standard or other document that refers to this test method. References to this document need to specify the particular options to be used. It is suitable for use at various temperatures, and in any suitable gaseous or liquid surrounding medium. This test method is not intended for measuring the dielectric strength of materials that are fluid under the conditions of test. This test method is not intended for use in determining intrinsic dielectric strength, direct-voltage dielectric strength, or thermal failure under electrical stress (see Test Method ASTM D3151). This test method is most commonly used to determine the dielectric breakdown voltage through the thickness of a test specimen (puncture). It is also suitable for use to determine dielectric breakdown voltage along the interface between a solid specimen and a gaseous or liquid surrounding medium (flashover). This test method is similar to IEC Publication 243-1. All procedures in this method are included in IEC 243-1. Differences between this method and IEC 243-1 are largely editorial. Note: The above information is taken directly from the test method Scope published in ASTM D149.

16451B -
Keysight Technologies
The 16451B is used to evaluate the dielectric constant of solid dielectric materials accurately, and complies with ASTM D150. The 16451B employs the parallel plate method, which sandwiches the material between two electrodes to form a capacitor. An LCR meter or an impedance analyzer is then used to measure the capacitance created from the fixture.

N1501A -
Keysight Technologies
The Keysight N1501A dielectric probe kit with N1500A materials measurement software suite with Option 004, and a Keysight network analyzer, determines the intrinsic electromagnetic properties of many dielectric materials. Because these properties are determined by the molecular structure, they can be related to other properties of interest as well. Measuring them can provide critical insight into applications in many industries.

ERAVANT
Dielectric resonator oscillators (DRO) are free running oscillators that utilize state-of-the-art planar circuits, three-terminal devices and dielectric resonator technology to generate high-quality microwave signals with excellent frequency stability. In addition, these oscillators are equipped with an internal voltage regulator that further improves the frequency stability by isolating the external bias pushing and modulation. In general, these oscillators are fixed. However, a small mechanical or electrical tuning range can be achieved by use of a self-locking screw or an integrated Varactor diode. The standard offering covers the frequency range of 2 to 40 GHz. While standard models are equipped with female SMA and K connectors at the RF port, other RF interface options are also available.
