26、oxy resin binder for post-impregnation (VPI) FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on al
27、l questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publi
28、cation(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. I
29、EC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of o
30、pinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made t
31、o ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparen
32、tly to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rend
33、ered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of i
34、ts technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any ot
35、her IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be th
36、e subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60371-3-5 has been prepared by IEC technical committee 15: Standards on specifications for electrical insulating materials. This bilingual version (2014-05) corresp
37、onds to the English version, published in 2005-11. This second edition cancels and replaces the first edition, published in 1992, and constitutes a technical revision. The main changes with regard to the previous edition include adjustments needed to align this standard with changes included in the
38、latest edition of IEC 60371-2. 4 IEC 60371-3-5:2005 IEC 2005 The text of this standard is based on the following documents: FDIS Report on voting 15/228/FDIS 15/246/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.
39、 The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site und
40、er “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. IEC 60371-3-5:2005 IEC 2005 5 INTRODUCTION This part of IEC 60371 forms part of a series which deals with insulating ma
41、terials built up from mica splittings or mica paper with or without reinforcement, and with mica paper in its pure state for use in electrical equipment IEC 60371 consists of three parts under the main title Specification for insulating materials based on mica: Part 1: Definitions and general requir
42、ements Part 2: Methods of test Part 3: Specifications for individual materials This standard contains one of the sheets comprising part 3, as follows: Sheet 5: Glass-backed mica paper with an epoxy resin binder for post-impregnation (VPI vacuum pressure impregnation) 6 IEC 60371-3-5:2005 IEC 2005 IN
43、SULATING MATERIALS BASED ON MICA Part 3: Specifications for individual materials Sheet 5: Glass-backed mica paper with an epoxy resin binder for post-impregnation (VPI) 1 Scope This part of IEC 60371 gives requirements for electrical insulating materials made by combining mica paper with glass fabri
44、c and bonding them together with a small amount of epoxy resin. The material is supplied in a flexible state and is designed for use in conjunction with vacuum pressure impregnation (VPI) with compatible impregnates. The final cured properties will be primarily dependent on the VPI resin used. Two b
45、ond contents are specified: low bond with a resin content of (8 3) %; medium bond with a resin content of (16 3) %. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the a
46、ctual 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 edition cited applies. For undated ref
47、erences, the latest edition of the referenced document (including any amendments) applies.

48、per ISO 5636-5:2003, Paper and board Determination of air permeance and air resistance (medium range) Part 5: Gurley method 3 Designation When ordering materials to this specification only the specification and type numbers need be quoted (see Tables 1 and 2). Example: IEC 60371-3-5: type 5.1.01 The
49、 type number is derived from: the specification sheet number 5 plus the sheet table number 5.1 plus the number of the product in the sheet table 5.1.01 IEC 60371-3-5:2005 IEC 2005 7 The descriptive code quoted in Tables 1 and 2, for example G23/M80/R08 for type 5.1.01, Table 1, is derived from: glass content (G) 23 g/m muscovite mica content (M) 80 g/m resin content
