IEC 60740-2:1993

IEC 60740-2:1993 defines requirements for laminations used in transformers and inductors for telecommunication and electronic equipment, with a focus on the minimum permeabilities of laminations made of soft magnetic metallic materials. For engineers, buyers, and compliance teams, the document helps align material selection and technical review with a clear performance reference. IEC 60740-2:1993 is relevant when evaluating core materials, comparing supplier data, or supporting documented evaluation during component procurement and verification activities.

What is IEC 60740-2:1993?

This technical document is the second part of the IEC 60740 series and addresses a specific material property for laminated soft magnetic metallic materials used in transformers and inductors. It is intended to support engineering specification, testing workflows, and conformity assessment where permeability limits are part of the acceptance basis. As an original edition, IEC 60740-2:1993 serves as the primary reference for defining minimum permeability expectations in telecommunication and electronic equipment design and review.

Applications of IEC 60740-2:1993

IEC 60740-2:1993 is commonly used in product development, supplier qualification, laboratory evaluation, and procurement review for magnetic components in electronic equipment. It may support technical validation of laminations intended for transformer and inductor assemblies, especially where consistent magnetic behavior is important to operational consistency and product evaluation. The document can also assist organizations preparing compliance workflows, comparing material certificates, or documenting acceptance criteria during component testing and engineering documentation control.

Why is IEC 60740-2:1993 important?

Clear permeability requirements help reduce ambiguity in technical assessment and improve consistency across design, testing, and purchasing decisions. For organizations working with transformers and inductors, IEC 60740-2:1993 can support risk management by providing a defined basis for material comparison and conformity assessment preparation. It is also useful for quality workflows that depend on repeatable verification activities, helping teams align supplier data, inspection records, and engineering validation with a shared compliance reference.
