This series consists of four parts: Part 1: Definitions, designations and general requirement
25、s (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 60893-3-4 contains one of the specification sheets comprising Part 3, as follows: Sheet 4: Requirements for rigid laminated sheets based on phe

27、Scope This part of IEC 60893 gives the requirements for industrial rigid laminated sheets for electrical purposes based on phenolic resin and different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet established leve
28、ls of performance. However, the selection of a material by a user 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 indi
29、spensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60893-1: , Insulating materials Industrial rigid laminated sheets based on thermosetting
