13、R ELECTRICAL PURPOSES Part 1: Definitions, designations and general requirements 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 prom
14、ote 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 International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides
15、 (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 participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC al
16、so participate in this preparation. IEC 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 poss
17、ible, an international consensus of opinion 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. Wh
18、ile 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 any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake
19、 to apply IEC Publications transparently 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 ind
20、icate 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 edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents includin
21、g 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 direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance
22、 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 indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the eleme
23、nts 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 61212- 1 has been prepared by IEC technical committee 15: Standards on specifications for electrical insulating materials. This
24、 second edition cancels and replaces the first edition published in 1995 and constitutes a technical revision. The main changes from the previous edition are as follows: added application use and safety statements. Reformatted document to bring it up to current IEC document format. Method for design
25、ation of tubes changed in line with common practice. New types EP GC 23 and PF CC 24 added. Type PF CP 24 removed. 4 61212- 1 IEC:2006(E) The text of this standard is based on the following documents: FDIS Report on voting 15/271/FDIS 15/304/RVD Full information on the voting for the approval of thi
26、s standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A bilingual version of this publication may be issued at a later date. The committee has decided that the contents of this publication wi
27、ll 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 amended. -,-,- 61212- 1 IEC:2006(E) 5 INT
28、RODUCTION This International Standard is one of a series which deals with industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes. This series consists of three parts: Part 1: Definitions, designations and general requirements (IEC 61212- 1) Part 2: Meth
29、ods of test (IEC 61212- 2) Part 3: Specifications for individual materials (IEC 61212- 3) 6 61212- 1 IEC:2006(E) INSULATING MATERIALS INDUSTRIAL RIGID ROUND LAMINATED TUBES AND RODS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 1: Definitions, designations and general requirements 1 Sco
30、pe This part of IEC 61212 gives the definitions related to the designations to be used for, and the general requirements to be fulfilled by, industrial rigid round laminated tubes and rods for electrical purposes made with any of the following resins as the binder: phenolic, epoxy (epoxide), melamin
31、e and silicone. The following reinforcements may be used either singly or in combination: cellulosic paper, woven cotton cloth, woven glass cloth, mica paper. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a sp
32、ecific 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 document to ensure that they are used i
33、n 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 any amendments) applies. IEC 61212
