IEC 61338-1-4:2005

IEC 61338-1-4:2005 defines a technical method for measuring the complex relative permittivity of dielectric resonator materials at millimetre-wave frequency. For engineers, laboratories, and procurement teams, it serves as a focused reference when evaluating material behavior in high-frequency waveguide applications. The document helps support consistent technical review, documented evaluation, and conformity assessment by giving a common basis for comparing test results and assessing whether a material is suitable for the intended resonator design or compliance workflow.

Purpose of IEC 61338-1-4:2005

The purpose of IEC 61338-1-4:2005 is to provide a standardized measurement method and defined test conditions for characterizing dielectric resonator materials used at millimetre-wave frequency. In practice, it supports laboratory evaluation of complex relative permittivity, which is a key parameter in material selection and engineering validation. By aligning the measurement approach, the document helps reduce variability between test setups and improves the reliability of technical assessment during design verification, quality workflows, and specification review.

Compliance applications of IEC 61338-1-4:2005

This technical document is relevant in compliance workflows where dielectric resonator materials must be assessed before use in waveguide-based components or high-frequency electronic equipment. It may be used by test laboratories, component manufacturers, and engineering teams preparing product evaluation records or procurement documentation. In regulatory preparation and internal verification activities, the method can help establish repeatable data for material comparison, supplier qualification, and technical validation of millimetre-wave designs.

Benefits of IEC 61338-1-4:2005

IEC 61338-1-4:2005 supports operational consistency by giving organizations a clear basis for measuring a material property that directly affects resonator performance. This can improve testing consistency, reduce risk in engineering decisions, and strengthen conformity assessment preparation. For procurement and quality assurance teams, the document offers a reference point for comparing technical offers, checking supplier data, and documenting compliance-related decisions with greater confidence.
