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
