About This Item
IEC 62631-2-1:2018 defines a technical basis for evaluating the dielectric and resistive properties of solid insulating materials, with emphasis on relative permittivity and dissipation factor at technical frequencies from 0.1 Hz to 10 MHz using AC methods. It is relevant where engineers need a documented evaluation method for insulation performance in electrical equipment and material qualification. For laboratories, procurement teams, and compliance workflows, IEC 62631-2-1:2018 supports consistent technical review, product evaluation, and conformity assessment against a clearly defined measurement approach.
Purpose of IEC 62631-2-1:2018
The purpose of IEC 62631-2-1:2018 is to provide a structured method for characterizing how solid insulating materials behave under alternating electrical stress across a broad technical frequency range. By focusing on relative permittivity and dissipation factor, it helps users compare materials, support engineering specification decisions, and align verification activities with repeatable test practice. This is especially useful when a documented technical reference is needed to support material selection, quality workflows, and technical validation in electrical and electronic applications.
Compliance applications of IEC 62631-2-1:2018
IEC 62631-2-1:2018 is commonly used in testing workflows for insulating materials intended for electrical components, assemblies, and other equipment where dielectric response matters. It can support laboratory evaluation, incoming material review, supplier documentation, and regulatory preparation when insulation performance must be assessed in a controlled and traceable way. In procurement and conformity assessment processes, it offers a clear compliance reference for comparing candidate materials and documenting technical assessment results in a consistent manner.
Benefits of IEC 62631-2-1:2018
Using IEC 62631-2-1:2018 can improve testing consistency and reduce uncertainty when evaluating solid insulating materials for electrical applications. A common method for measuring dielectric and resistive properties helps teams compare results across projects, suppliers, and laboratories, supporting operational consistency and risk management. It also strengthens engineering documentation by giving quality and compliance teams a reliable basis for technical review, procurement decisions, and preparedness for conformity assessment. For organizations working with insulation performance, the document helps turn measurement data into usable compliance evidence.
