23、ardization 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 this end and in addition to other activities, IEC publishes Int
24、ernational 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 National Committee interested in the subject dealt with may participa
25、te 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 (ISO) in accordance with conditions determined by agreement between
26、 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 from all interested IEC National Committees. 3) IEC Publications
27、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 held responsible for the way in which they are used or for any m
28、isinterpretation 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 divergence between any IEC Publication and the corresponding na
29、tional 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 IEC marks of conformity. IEC is not responsible for any service
30、s 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 individual experts and members of its technical committees and IEC Nation
31、al 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 IEC Publication or any other IEC Publications. 8) Attention is
32、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 IEC Publication may be the subject of patent rights. IEC shall
33、not be held responsible for identifying any or all such patent rights. International Standard IEC 60317-20 has been prepared by IEC technical committee 55: Winding wires. This third edition cancels and replaces the second edition published in 1990, Amendment 1:1997 and Amendment 2:1999. This edition
34、 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 references to IEC 60317-0-1:2013 to clarify that their application
35、is normative; modification to Clause 15 to remove specific wire specimen sizes; consolidation of 17.1 and 17.2 of the solderability requirements; modification to Clause 19, Dielectric dissipation factor; new Clause 23, Pin hole test. 4 60317-20 IEC:2013 The text of this standard is based on the foll
36、owing documents: FDIS Report on voting 55/1411/FDIS 55/1432/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
37、 in 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
38、to 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,
39、withdrawn, replaced by a revised edition, or amended. 60317-20 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) Specifica
40、tions for particular types of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264). 6 60317-20 IEC:2013 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 20: Solderable polyurethane enamelled round copper wire, class 155 1 Scope This part of IEC 60317 specifies the requiremen
41、ts of solderable enamelled round copper winding wire of class 155 with a sole coating based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requirements. NOTE A modified resin is a resin that has undergone a c
42、hemical 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: 0,018 mm up to and including 0,800 mm; Grade 2: 0,020 mm up to and including 0,800 mm. The nominal conductor
43、 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 for its application. For dated references, only the edition cited applies. For undated references, the la
44、test 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 copper wire 3 Terms, definitions, general notes and appearance 3.1 Terms and definitions Subclause 3.1 o
45、f 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 60317, the latter shall prevail. 3.2.2 Winding wire Class 155 is a thermal class that requires a minimum tem
46、perature index of 155 and a heat shock temperature of at least 175 C. The temperature in degrees Celsius corresponding to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved.
47、 60317-20 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 Elongation Clause 6 of IEC 60317-0-1:2013 applies. 7 Springiness Clause 7 of IEC 60317-0-1:2013 appl
48、ies. 8 Flexibility and adherence Clause 8 of IEC 60317-0-1:2013 applies. 9 Heat shock Clause 9 of IEC 60317-0-1:2013 applies. The minimum heat shock temperature shall be 175 C. 10 Cut-through No failure shall occur within 2 min at 200 C. 11 Resistance to abrasion (nominal conductor diameters from 0,
49、250 mm up to and including 0,800 mm) The wire shall meet the requirements given in Table 1. For intermediate nominal conductor diameters, the value of the next larger nominal conductor diameter shall be taken. 8 60317-20 IEC:2013 Table 1 Resistance to abrasion Nominal conductor diameter Grade 1 Grade 2 Minimum average force to failure Minimum force to failure of each measurement Minimum average force to failure
