23、onal 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 all questions concerning standardization in the electrical and electroni
24、c 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 Publication(s)”). Their preparation is entrusted to technical committees; a
25、ny 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. IEC collaborates closely with the International Organization for Standa
26、rdization (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 opinion on the relevant subjects since each technical committee has rep
27、resentation 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 to ensure that the technical content of IEC Publications is accurate, I
28、EC 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 transparently to the maximum extent possible in their national and regional publ
29、ications. 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 rendered responsible for any equipment declared to be in conformity with a
30、n 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 its technical committees and IEC National Committees for any personal i
31、njury, 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 other IEC Publications. 8) Attention is drawn to the Normative reference
32、s 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 the subject of patent rights. IEC shall not be held responsible for iden
33、tifying any or all such patent rights. International Standard IEC 61212-2 has been prepared by IEC technical committee 15: Standards on specifications for electrical insulating materials. This second edition cancels and replaces the first edition published in 1995 and constitutes a technical revisio
34、n. 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. Test method references updated. 4 61212-2 IEC:2006 This bilingual version, published in 2009-06, corresponds to the English v
35、ersion. The text of this standard is based on the following documents: FDIS Report on voting 15/273/FDIS 15/306/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. The French version of this standard has not been vot
36、ed 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 under “http:/webstore.iec.ch“ in the data related to the
37、 specific publication. At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 61212-2 IEC:2006 5 INTRODUCTION This part of IEC 61212 is one of a series which deals with industrial, rigid, round, laminated tubes and rods based on thermosetting resins
38、for electrical purposes. The materials are similar to those described in IEC 62011-1 but of different cross-section. This series, under the general heading Insulating materials Industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes, consists of three pa
39、rts: Part 1: Definitions, designations and general requirements (IEC 61212-1) Part 2: Methods of test (IEC 61212-2) Part 3: Specifications for individual materials (IEC 61212-3) 6 61212-2 IEC:2006 INSULATING MATERIALS INDUSTRIAL RIGID ROUND LAMINATED TUBES AND RODS BASED ON THERMOSETTING RESINS FOR
40、ELECTRICAL PURPOSES Part 2: Methods of test 1 Scope This part of IEC 61212 describes methods of test for the materials defined in IEC 61212-1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific applicati
41、on 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 in a safe manner.
