The series consists of three parts: Part 1: Definitions and general requirements (IEC 60455-
19、1) Part 2: Methods of test (IEC 60455-2) Part 3: Specifications for individual materials (IEC 60455-3) IEC 60455-3-2 is one of the specification sheets comprising Part 3, as follows: Sheet 2: Quartz filled epoxy resinous compounds Page3 EN6045532:2003RESIN BASED REACTIVE COMPOUNDS USED FOR ELECTRICA
20、L INSULATION Part 3: Specifications for individual materials Sheet 2: Quartz filled epoxy resinous compounds 1 Scope This part of IEC 60455 contains the requirements for quartz filled epoxy resinous compounds in the cured form for types EP-F-1 to EP-F-7. Other materials than quartz may be introduced
21、 later. 2 Normative references The following referenced documents are indispensable 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 60455-2:1998,
22、Resin-based reactive compounds used for electrical insulation Part 2: Methods of test 3 Requirements The requirements for quartz filled epoxy resinous compounds in the cured form are given in Table 2. If not otherwise specified, the requirements are for (23 2) C. NOTE 1 Materials with fillers differ
23、ent from quartz may be added as additional tables. Quartz filled epoxy resinous compounds purporting to comply with this standard shall contain between 45 % and 65 % by mass of quartz filler. NOTE 2 Materials for use in lower or higher temperature conditions may require additional tests to establish
24、 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.
