31、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 International Standards, Technical Specifications, Tech
32、nical 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 participate in this preparatory work. International, governme
33、ntal 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 between the two organizations. 2) The formal decisions or a
34、greements 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 Publications have the form of recommendations for international u
35、se 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 any misinterpretation by any end user. 4) In order to pro
36、mote 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 corresponding national or regional publication shall be clearly indi
37、cated 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 edition of this publication. 7) No liability shall attach
38、 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 direct or indirect, or for costs (including legal fees)
39、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 indispensable for the correct application of this publication.
40、 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 60851-3 has been prepared by IEC technical committee 55: Windin
41、g wires. This third edition cancels and replaces the second edition, published in 1996, its amendment 1 (1997) and its amendment 2 (2003), and constitutes a technical revision. With respect to the previous edition, significant technical changes appear in Subclause 5.3, Jerk test. 60851-3 IEC:2009 5
42、The text of this standard is based on the following documents: CDV Report on voting 55/1043/CDV 55/1059/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO
43、/IEC Directives, Part 2. A list of all the parts in the IEC 60851 series, under the general title Winding wires Test methods, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC
44、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. 6 60851-3 IEC:2009 INTRODUCTION This part of IEC 60851 forms an element of a series of standards, which dea
45、ls with insulated wires used for windings in electrical equipment. The series has three groups describing a) winding wires Test methods (IEC 60851); b) specifications for particular types of winding wires (IEC 60317); c) packaging of winding wires (IEC 60264). 60851-3 IEC:2009 7 WINDING WIRES TEST M
46、ETHODS Part 3: Mechanical properties 1 Scope This part of IEC 60851 specifies the following methods of test for winding wires: Test 6: Elongation; Test 7: Springiness; Test 8: Flexibility and adherence; Test 11: Resistance to abrasion; Test 18: Heat bonding. For definitions, general notes on methods
47、 of test and the complete series of methods of test for winding wires, see IEC 60851-1. 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 o
48、f the referenced document (including any amendments) applies.

49、 Elongation at fracture Elongation is the increase in length expressed as a percentage of the original length. A straight piece of wire shall be elongated to the point of fracture of the conductor at a rate of (5 1) mm/s with an elongation tester or with tensile testing equipment with a free measuring length of between 200 m
