IEC 60674-3-4:2022 gives the requirements for polyimide films used for electrical purposes. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application is based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.Safety warning: it is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. This second edition cancels and replaces the first edition published in 1993. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: this document has been completely revised editorially and technically and included in the IEC 60674 series of standards; new types have been included; the ranges of thickness have been expanded; changes have been made to the requirements of some existing types.
