T/CSTM 00751-2022 Active

Scope: This document specifies the method of measuring the dielectric constant and loss tangent of solid dielectric and composite board materials in the frequency range of 1 GHz to 20 GHz using the closed-cavity method. Among them, the test range of dielectric constant is 5 to 100, and the test range of loss tangent is 0.00005 to 0.005. This document is applicable to the measurement of dielectric constant and loss tangent of inorganic materials such as silicon oxide, aluminum oxide, aluminum nitride, zirconium oxide, and boron nitride, and organic-inorganic composite materials that can be processed into cylindrical shapes.
