EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62631-2-2 test. IEC EN 62631-2-2 specifies test methods for the determination of transmittance and dispersion factor properties of solid insulating materials in the high frequency range from 1 MHz to 300 MHz.

The dielectric and resistive properties of solid insulating materials are important parameters that determine their suitability for use in electrical and electronic applications. Two key properties commonly measured for solid insulating materials are relative permittivity and dispersion factor, especially at high frequencies from 1 MHz to 300 MHz. AC methods are typically used to measure these properties.

Relative permittivity, also known as the dielectric constant, is a measure of a material's ability to store electrical energy in an electric field. It is defined as the ratio of the capacitance of a material to the capacitance of a vacuum or air. A high relative permittivity indicates that a material can store more electrical energy and is often desired for applications such as capacitors and dielectric coatings. However, high relative permeability can also lead to increased signal loss and interference in high frequency applications.

Dissipation factor, also known as tangential delta, is a measure of the energy lost in a material when exposed to an alternating electric field. It is defined as the ratio of the power lost in the material to the power transmitted through the material. A low dissipation factor is desirable for applications where energy efficiency is important, such as high frequency transformers and inductors. High dispersion factors may indicate the presence of impurities or defects in the material.

In AC methods, the relative permittivity and dissipation factor of a solid insulating material are typically measured using a high frequency test apparatus. This apparatus applies an alternating electric field to the material and measures the resulting current and voltage. By analyzing the phase relationship between current and voltage, the relative permittivity and dissipation factor can be calculated.

Accurate measurements of the relative permittivity and dispersion factor are important to ensure reliable performance of electrical and electronic equipment. Manufacturers of solid insulation materials use these metrics to ensure their products meet required quality and performance standards.
