The series consists of three parts: Part 1: Definitions and general requirements (IEC 60455-1) Part 2: Methods of
19、test (IEC 60455-2) Part 3: Specifications for individual materials (IEC 60455-3) IEC 60455-3-1 is one of the specification sheets comprising Part 3, as follows: Sheet 1: Unfilled epoxy resinous compounds Page3 EN6045531:2003RESIN BASED REACTIVE COMPOUNDS USED FOR ELECTRICAL INSULATION Part 3: Specif
20、ications for individual materials Sheet 1: Unfilled epoxy resinous compounds 1 Scope This part of IEC 60455 contains the requirements for unfilled epoxy resinous compounds in the cured form for classes EP-U-1 to EP-U-7. 2 Normative references The following referenced documents are indispensable for
21、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.

22、Requirements The requirements for unfilled epoxy resinous compounds in the cured form are given in Table 2. If not otherwise specified, the requirements are for (23 2) C. NOTE Materials for use in lower or higher temperature conditions may require additional tests, not specified in this sheet, to es
23、tablish their suitability. 4 Special requirements When any of the following special properties are prescribed in the purchase contract, the method of test given below shall be used: Table 1 Requirements for unfilled epoxy resinous compounds in the uncured form Property Method of test in IEC 60455-2
