IEC 61338-1-3:1999

IEC 61338-1-3:1999 defines a technical method for measuring the complex relative permittivity of dielectric resonator materials at microwave frequency, which makes it relevant to laboratories, design teams, and procurement specialists evaluating material data for resonator applications. By focusing on a consistent measurement approach, IEC 61338-1-3:1999 supports more reliable technical review, documented evaluation, and comparison of material properties used in microwave component development. Organizations involved in verification activities or conformity assessment can use it to align test practice with an established reference.

IEC 61338-1-3:1999 standard overview

The official title indicates a measurement method within the Waveguide type dielectric resonators series, covering general information, test conditions, and the determination of complex relative permittivity for dielectric resonator materials at microwave frequency. In practical terms, the document is likely used to support repeatable laboratory evaluation and engineering documentation when material characteristics need to be assessed for design or qualification work. For teams handling technical validation, it can serve as a structured compliance reference for comparing results across test setups and ensuring operational consistency.

Applications of IEC 61338-1-3:1999

This publication is most relevant to microwave materials characterization, resonator development, and laboratory testing workflows where dielectric properties must be measured with controlled conditions. It may be used during product evaluation, supplier qualification, and quality workflows for components or materials intended for microwave-frequency use. Engineering groups and test laboratories can apply IEC 61338-1-3:1999 when preparing technical assessments, reviewing measurement reports, or building internal procedures that depend on dependable permittivity data for design decisions and compliance preparation.

Why IEC 61338-1-3:1999 matters

Reliable permittivity measurement helps reduce risk in engineering validation by improving the consistency of material data used in microwave resonator design and related testing programs. IEC 61338-1-3:1999 supports documented evaluation, procurement review, and conformity assessment preparation by providing a defined measurement approach rather than relying on ad hoc methods. For organizations managing technical compliance, the document can improve comparison between suppliers, strengthen testing consistency, and support more defensible decisions in technical review and acceptance workflows.
