25、 IEC 2006 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SPECIFICATION FOR INSULATING MATERIALS BASED ON MICA Part 3: Specifications for individual materials Sheet 1: Commutator separators and materials FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for st
26、andardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes
27、International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may partic
28、ipate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement bet
29、ween the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publicati
30、ons have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to 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 a
31、ny misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the correspondin
32、g national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest e
33、dition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether
34、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 other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indisp
35、ensable 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 the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60371-3
36、-1 has been prepared by IEC technical committee 15: Insulating materials. This bilingual version (2014-05) corresponds to the English version, published in 2006-06. This third edition of IEC 60371-3-1 replaces the second edition, published in 1984, and constitutes a technical revision. The main chan
37、ges with regard to the previous edition concern the modification of clause numbers to align with clause numbering in the latest edition of IEC 60371-2:2004. 4 IEC 60371-3-1:2006 IEC 2006 The text of this standard is based on the following documents: FDIS Report on voting 15/307/FDIS 15/330/RVD Full
38、information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. 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 t
39、hat the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “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 am

IEC 60371-3-1:2006 IEC 2006 5 INTRODUCTION This part of IEC 60371 forms part of a series which deals with insulating materials 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
41、of three parts under the main title Specification for insulating materials based on mica: Part 1: Definitions and general requirements Part 2: Methods of test Part 3: Specifications for individual materials This standard contains one of the sheets comprising part 3, as follows: Sheet 1: Commutator s
42、eparators and materials 6 IEC 60371-3-1:2006 IEC 2006 SPECIFICATION FOR INSULATING MATERIALS BASED ON MICA Part 3: Specifications for individual materials Sheet 1: Commutator separators and materials 1 Scope This sheet of IEC 60371-3 applies to several types of rigid materials based on mica splittin
43、gs or mica paper for commutator separators. These products shall be made from muscovite or phlogopite mica, built up from mica splittings or mica paper by the use of a suitable bonding medium. They are supplied in the following forms: sheets in the dimensions in which they are pressed or after trimm
44、ing; strips cut from sheets; commutator separators having the shapes and dimensions and in the conditions ordered by the user. The normal manufacturing thicknesses lie between 0,3 mm and 2 mm. Materials which conform to this specification meet established levels of performance. However, the selectio
45、n of 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. Safety warning: It is the responsibility of the user of the methods contained or referred to in this documen
46、t to ensure that they are used in a safe manner. 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 an
47、y amendments) applies. IEC 60371-2:2004, Specification for insulating materials based on mica Part 2: Methods of test 3 General requirements The material as supplied shall be of uniform hardness, free from soft patches and foreign matter. The bonding medium used shall be agreed between supplier and
48、purchaser. The materials, when tested in accordance with the methods given in IEC 60371-2, shall comply with the requirements of this publication. IEC 60371-3-1:2006 IEC 2006 7 4 Thickness 4.1 Definition of nominal thickness The nominal thickness is that stated when ordering, being the thickness on
49、delivery (before assembly of the commutator). 4.2 Measurements and tolerances The tolerances with respect to the nominal thickness, in millimetres, are given in Tables 1 and 2. 4.2.1 Sheets, strips and separators having a surface area 10 cm 2Specimen: as in 4.2.1 and 4.2.4 of IEC 60371-2. The thickness shall be measured with the apparatus given in 4.1.3 of that standard (diameter of measuring fac
