24、ications for individual materials (IEC 60893-3) Part 4: Typical values (IEC 60893-4) IEC 60893-3-6 contains one of the specification sheets comprising Part 3, as follows: Sheet 6: Requirements for rigid laminated sheets based on silicone resins Page 4BS EN 60893-3-6:2004+A1:2009EN 60893-3-6:2004+A1:
25、2009 (E)INSULATING MATERIALS INDUSTRIAL RIGID LAMINATED SHEETS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 3-6: Specifications for individual materials Requirements for rigid laminated sheets based on silicone resins 1 Scope This part of IEC 60893 gives the requirements for industrial
26、 rigid laminated sheets for electrical purposes based on silicone 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
27、 for a specific application 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 referen
28、ces, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、ts 1IEC 60893-2:2003, Industrial rigid laminated sheets based on thermosetting resins for electrical purposes Part 2: Methods of test 3 Designation The sheets covered by this specification are classified into types, which differ in the reinforcement employed and in their distinguishing properties. T
30、he 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 mm. _ 1To be published.
