24、technical 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 electronic fields. To
25、 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; any IEC Natio
26、nal 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 Standardization (IS
27、O) 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 representation f
28、rom 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, IEC cannot be
29、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 publications. Any
30、 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 assessment services and, in some areas, access to
31、 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, employees, servants or agents including individua
32、l 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 upon, this
33、 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 elements of this
34、 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 60317-21 has been prepared by IEC Technical Committee 55: Winding wires. This third edition cancels and replaces the second edition publis
35、hed in 1990, Amendment 1:1997 and Amendment 2:1999. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: new 3.2.2 containing general notes on winding wire, formerly a part of the scope; revision to ref
36、erences to IEC 60317-0-1:2013 to clarify that their application is normative; consolidation of 17.1 and 17.2 of the solderability requirements; modification to Clause 19, Dielectric dissipation factor; 4 60317-21 IEC:2013 new Clause 23, Pin hole test. The text of this standard is based on the follow
37、ing documents: FDIS Report on voting 55/1412/FDIS 55/1433/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 ISO/IEC Directives, Part 2. A list of all parts i
38、n the IEC 60317 series, published under the general title Specifications for particular types of winding wires, can be found on the IEC website. The numbering of clauses in this standard is not continuous from Clauses 20 and 30 in order to reserve space for possible future wire requirements prior to
39、 those for wire packaging. The committee has decided that the contents of this publication will remain unchanged until the stability 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, wi
40、thdrawn, replaced by a revised edition, or amended. 60317-21 IEC:2013 5 INTRODUCTION This part of IEC 60317 is one of a series which deals with insulated wires used for windings in electrical equipment. The series has three groups describing: 1) Winding wires Test methods (IEC 60851); 2) Specificati
41、ons for particular types of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264). 6 60317-21 IEC:2013 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 21: Solderable polyurethane enamelled round copper wire overcoated with polyamide, class 155 1 Scope This part of IEC 60317
42、specifies the requirements of solderable enamelled round copper winding wire of class 155 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. The
43、superimposed coating is based on polyamide resin. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor diameters covered by this standard is: Grade 1: 0,0
44、50 mm up to and including 1,600 mm; Grade 2: 0,050 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable
45、for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60317-0-1:2013, Specifications for particular types of winding wires Part 0-1: General requirements Enamelled round
46、 copper wire 3 Terms, definitions, general notes and appearance 3.1 Terms and definitions Subclause 3.1 of IEC 60317-0-1:2013 applies. 3.2 General notes 3.2.1 Methods of test Subclause 3.2.1 of IEC 60317-0-1:2013 applies. In case of inconsistencies between IEC 60317-0-1:2013 and this part of IEC 603
47、17, the latter shall prevail. 3.2.2 Winding wire Class 155 is a thermal class that requires a minimum temperature index of 155 and a heat shock temperature of at least 175 C. The temperature in C corresponding to the temperature index is not necessarily that at which it is recommended that the wire
48、be operated and this will depend on many factors, including the type of equipment involved. 60317-21 IEC:2013 7 3.3 Appearance Subclause 3.3 of IEC 60317-0-1:2013 applies. 4 Dimensions Clause 4 of IEC 60317-0-1:2013 applies. 5 Electrical resistance Clause 5 of IEC 60317-0-1:2013 applies. 6 Elongatio
49、n Clause 6 of IEC 60317-0-1:2013 applies. 7 Springiness Clause 7 of IEC 60317-0-1:2013 applies. 8 Flexibility and adherence Clause 8 of IEC 60317-0-1:2013 applies. For 8.4, the constant K used for the calculation of the number of revolutions for the peel test shall be 150 mm. 9 Heat shock Clause 9 of IEC 60317-0-1:2013 applies.
