20、TIONAL ELECTROTECHNICAL COMMISSION _ WINDING WIRES TEST METHODS Part 2: Determination of dimensions FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The objec

21、t 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, Technical Reports, Publicly Available Specification

22、s (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, governmental and non-governmental organizations liaisin

23、g 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 agreements of IEC on technical matters express,

24、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 use and are accepted by IEC National Committees

25、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 promote international uniformity, IEC National Com

26、mittees 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 indicated in the latter. 5) IEC provides no marking

27、 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 to IEC or its directors, employees, servants o

28、r 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 publication, us

29、e 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 possibility that

30、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 60851-2 has been prepared by IEC technical committee 55: Winding wires. This third edition cancels and replace

31、s the second edition published in 1996 and its amendment 1 (1997) and amendment 2 (2003), and constitutes a technical revision. Technical revisions of note include recognition of the use of optical micrometers in determining the dimensions of round and rectangular enamelled wire. 4 60851-2 IEC:2009

32、The text of this standard is based on the following documents: FDIS Report on voting 55/1144/FDIS 55/1163/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. This publication has been drafted in accordance with the I

33、SO/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 IE

34、C 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. 60851-2 IEC:2009 5 INTRODUCTION This part of IEC 60851 forms an element of a series of standards which de

35、als with insulated wires used for windings in electrical equipment. The series has three groups describing a) methods of test (IEC 60851); b) specifications (IEC 60317); c) packaging (IEC 60264). 6 60851-2 IEC:2009 WINDING WIRES TEST METHODS Part 2: Determination of dimensions 1 Scope This part of I

36、EC 60851 specifies the following method of test: Test 4: Dimensions. For definitions, general notes on methods 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 thi

37、s document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

38、es 3 Test 4: Dimensions 3.1 Equipment 3.1.1 Round and rectangular wire The equipment used shall have a resolution of 2 m or less for wires over 0,200 mm and for wires up to and including 0,200 mm, a resolution of 1 m or less. Both mechanical contact and optical non-contact micrometers may be used. I

39、f mechanical contact micrometers are used, the ratio of measuring force and anvil diameter shall be in accordance with the range as given in Table 1a and Table 1b. The diameter range of the spindle and anvil is also given in Table 1a and Table 1b. If optical micrometers are used, the average of the

40、readings shall be recorded as the diameter of the conductor. If a specific measuring equipment must be used, it shall be agreed upon between the customer and the supplier.

42、 diameters over 0,063 mm and up to and including 1,000 mm. 3.2.5.2 Rectangular wire On a straight piece of wire at each of three places at least 100 mm apart, one measurement shall be made of the two dimensions of the wire. Where the dimension of the specimen is greater than the diameter of the micr

43、ometer spindle, measurements shall be made both at the centre of the face of the specimen and over the edges. If these values differ, only the highest value shall be noted. The three single values shall be reported for each dimension of the wire. The mean values represent the overall width or the ov

44、erall thickness respectively. 3.2.5.3 Bunched wire NOTE The method indicated below gives useful values in practice, but not an accurate overall diameter. The overall diameter is the width of a layer wound on a mandrel divided by the number of turns. The bunched wire shall be wound closely on a mandr

45、el according to Figure 1 and under a tension in newtons, which is 65 times the total nominal cross-section of the conductors in square millimetres. The width of the layer shall be not less than 10 mm for bunched wires with overall diameters up to and including 0,5 mm, and be not less than 20 mm for

46、larger diameters and shall be measured with a precision of 0,5 mm. One measurement shall be made. The overall diameter rounded off to 0,01 mm shall be reported. 3.2.6 Increase in diameter due to the bonding layer of enamelled round wire The increase in diameter due to the bonding layer is the differ

47、ence of the overall diameter with and without the bonding layer. The overall diameter of the wire shall be measured according to 3.2.5.1. After removal of the bonding layer by means of a solvent or any other suitable agent or by any other method which does not damage the underlying coating, the meas

48、urement shall be repeated. The difference of the two mean values shall be reported as the increase in diameter due to the bonding layer. 10 60851-2 IEC:2009 Dimensions in millimetres Cne 1:390 10 60IEC 1842/09 Figure 1 Conical mandrel _ 12 60851-2 CEI:2009 SOMMAIRE AVANT-PROPOS13 INTRODUCTION.15 1 D
