26、 WIRES 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 all questions concerning standardization

27、 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 Publication(s)”). Their preparation is entr

28、usted 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. IEC collaborates closely with the Intern

29、ational 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 opinion on the relevant subjects since e

30、ach 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 to ensure that the technical content of

31、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 transparently to the maximum extent possible in t

32、heir 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity asses

33、sment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, emplo

34、yees, 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 direct or indirect, or for costs (including legal fees) and expenses arising out of the

35、 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 indispensable for the correct application of this publication. 9) Attention is drawn to the p

36、ossibility 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 60172 has been prepared by IEC Technical Committee 55: Winding wires. This fourth edition canc

37、els and replaces the third edition published in 1987, Amendment 1:1997 and Amendment 2:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Revision of Clause 1, Scope, to incorporate appropriate

38、text from former Clause 2, Object; Deletion of Clause 2, Object, by placement of its text into existing clauses; New Clause 2, Normative references; Revision of 5.1.1, 5.3 and 5.4 with corrections to Amendment 2 to the third edition; Revision of Clause 7 as to clarify which specimens comply with Tab

39、le 3 and Table 4; Revision of figures with high-resolution photos and graphs. BS EN 60172:2015IEC 60172:2015 IEC 2015 5 The text of this standard is based on the following documents: FDIS Report on voting 55/1518/FDIS 55/1524/RVD Full information on the voting for the approval of this standard can b

40、e 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. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/

41、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. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to

42、 be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. BS EN 60172:2015 6 IEC 60172:2015 IEC 2015 TEST PROCEDURE FOR THE DETERMINATION OF THE TEMPERATURE INDEX OF ENAMELLED AND TAPE WRAPPED WINDING WIRES 1 Scope This International

43、 Standard specifies, in accordance with the provisions of IEC 60216-1, a method for evaluating the temperature index of enamelled wire, varnished or unvarnished with an impregnating agent, and of tape wrapped round and rectangular wire, in air at atmospheric pressure by periodically monitoring chang

44、es in response to AC proof voltage tests. This procedure does not apply to fibre-insulated wire or wire covered with tapes containing inorganic fibres. NOTE The data obtained according to this test procedure provide the designer and development engineer with information for the selection of winding

45、wire for further evaluation of insulation systems and equipment tests. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated referen

46、ces, the latest edition of the referenced document (including any amendments) applies. IEC 60216-1, Electrical insulating materials Thermal endurance properties Part 1: Ageing procedures and evaluation of test results IEC 60216-3, Electrical insulating materials Thermal endurance properties Part 3:

47、Instructions for calculating thermal endurance characteristics 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 temperature index TI numerical value of the Celsius temperature expressed in degrees Celsius characterizing the thermal capability

48、of an insulating material or an insulation system Note 1 to entry: In case of insulating materials, the temperature index is derived from the thermal endurance relationship at a given time, normally 20 000 hours. It may be used as basis for determination of the materials temperature class. Note 2 to

49、 entry: In case of insulation systems, the temperature index may be derived from known service experience or from a known comparative functional evaluation of an evaluated and established reference insulation system as basis.
