24、thermosetting resins for electrical purposes. This series consists of four parts: Part 1: Definitions, designations and general requirements (IEC 60893-1) Part 2: Methods of test (IEC 60893-2) Part 3: Specifications for individual materials (IEC 60893-3) Part 4: Typical values (IEC 60893-4) IEC 6089

26、ATERIALS INDUSTRIAL RIGID LAMINATED SHEETS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 3-3: Specifications for individual materials Requirements for rigid laminated sheets based on melamine resins 1 Scope This part of IEC 60693 gives the requirements for industrial rigid laminated she
27、ets for electrical purposes based on melamine resins and different 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 appl
28、ication should be based on the actual requirements necessary 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 editio
29、n cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Th
31、e sheets are designated by the IEC standard number, a two-letter abbreviation denoting the resin, a second two-letter abbreviation, denoting the reinforcement, a serial number, nominal thickness x width x length in millimetres. 1To be published Page5 EN6089333:2004Licensed Copy: Wang Bin, ISO/Exchan
