IEC TR 63304:2021

IEC TR 63304:2021 addresses methods for measuring the magnetic properties of permanent magnet materials in an open magnetic circuit using a superconducting magnet. For engineers, laboratories, and procurement teams, it provides a technical reference for evaluating how magnetically hard materials are characterized under controlled measurement conditions. The document is relevant when documented evaluation, testing workflows, and technical validation are needed to support material selection, product development, or conformity assessment in applications that depend on consistent magnetic performance.

Purpose of IEC TR 63304:2021

The purpose of IEC TR 63304:2021 is to describe a measurement approach for permanent magnet materials where the magnetic circuit is open and a superconducting magnet is used as part of the test arrangement. That makes it useful for technical review and laboratory evaluation of magnetic properties with a focus on repeatability and operational consistency. The title indicates a methods-oriented document rather than a product requirement set, so it is especially relevant when organizations need a defined basis for comparing results across testing workflows.

Compliance applications of IEC TR 63304:2021

IEC TR 63304:2021 may be used in research, quality assurance, and product evaluation workflows involving permanent magnet materials for electrical equipment, sensors, actuators, or other magnetic assemblies. It can support compliance preparation by giving laboratories and engineering teams a shared reference for measurement setup, result interpretation, and technical documentation. In procurement and supplier qualification, it may also help define how magnetic property data should be generated and reviewed before acceptance into a design or manufacturing process.

Benefits of IEC TR 63304:2021

Using IEC TR 63304:2021 can improve testing consistency and reduce uncertainty when assessing magnetically hard materials. A clearly defined measurement method supports technical validation, risk management, and more reliable comparison of data from different test environments. For organizations involved in conformity assessment or engineering documentation, it can strengthen traceability and help align laboratory results with internal quality workflows. It is also useful when procurement decisions depend on verified magnetic performance rather than vendor declarations alone.
