25、ING RESINS FOR ELECTRICAL PURPOSES Part 3-7: Specifications for individual materials Requirements for rigid laminated sheets based on polyimide resins 1 Scope This part of IEC 60893 gives the requirements for industrial rigid laminated sheets for electrical purposes based on polyimide resins and dif
26、ferent reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary
27、 for adequate performance in that application and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition

The sheets are designated by the IEC standard number; a two-
30、letter abbreviation, denoting the resin; a second two-letter abbreviation denoting the reinforcement; a serial number; nominal thickness x width x length in mm. Example of designation: Industrial rigid laminated sheet of type PI GC 301 with a nominal thickness of 10 mm, 500 mm wide, 1 000 mm long. S
