About This Item

Legal Notices*

IEC 60371-3-4:1992/AMD1:2006 is a supporting amendment to the base specification for insulating materials based on mica, focused on polyester film-backed mica paper with a B-stage epoxy resin binder. It is relevant when teams need a precise technical reference for material definition, review, or procurement decisions tied to mica-based electrical insulation. As an amendment to IEC 60371-3-4:1992, it should be used alongside the parent document to support documented evaluation, conformity assessment, and engineering documentation workflows.

Overview of IEC 60371-3-4:1992/AMD1:2006

This amendment updates the specific material sheet within the IEC 60371 series for insulating materials based on mica. Its likely purpose is to refine the technical reference for polyester film-backed mica paper with a B-stage epoxy resin binder so that manufacturers, laboratories, and purchasers can align specifications more consistently. In practice, IEC 60371-3-4:1992/AMD1:2006 is used as a compliance reference during technical review, product evaluation, and quality workflows where material identification and specification control matter.

Compliance applications of IEC 60371-3-4:1992/AMD1:2006

Organizations may use this amendment when reviewing electrical insulation materials intended for apparatus where mica-based products are selected for thermal or dielectric performance considerations. It can support procurement specifications, supplier declarations, and laboratory evaluation by clarifying the amended reference for the relevant material sheet. IEC 60371-3-4:1992/AMD1:2006 is also useful in technical documentation packages that track parent standards and subsequent modifications during verification activities and regulatory preparation.

Importance of compliance with IEC 60371-3-4:1992/AMD1:2006

Using the correct amended reference helps reduce ambiguity in material selection and supports consistent conformity assessment across engineering and procurement teams. Because it modifies a parent specification rather than standing alone, it is important for maintaining operational consistency, especially when suppliers, test laboratories, and internal reviewers must work from the same technical basis. IEC 60371-3-4:1992/AMD1:2006 can therefore contribute to safer material selection, more reliable testing workflows, and better risk management in electrical equipment documentation.

  • Supports amended technical identification for polyester film-backed mica paper with a B-stage epoxy resin binder
  • Helps align procurement and supplier review with the parent specification IEC 60371-3-4:1992
  • Useful for documentation control in conformity assessment and engineering validation workflows
  • Assists laboratories and quality teams with traceable material reference management
