18、 worldwide organization for standardizationcomprising all national electrotechnical committees (IEC National Committees). The object of the IEC is topromote international cooperation on all questions concerning standardization in the electrical andelectronic fields. To this end and in addition to ot

19、her activities, the IEC publishes International Standards.Their preparation is entrusted to technical committees; any IEC National Committee interested inthe subject dealt with may participate in this preparatory work. International, governmental andnon-governmental organizations liaising with the I

20、EC also participate in this preparation. The IECcollaborates closely with the International Organization for Standardization (ISO) in accordance withconditions determined by agreement between the two organizations.2) The formal decisions or agreements of the IEC on technical matters, express as near

21、ly as possible aninternational consensus of opinion on the relevant subjects since each technical committee hasrepresentation from all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in theform of standards, technical

22、reports or guides and they are accepted by the National Committees in thatsense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence

23、 between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Attent

24、ion is drawn to the possibility that some of the elements of this International Standard may be thesubject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 851-1 has been prepared by IEC technical committee 55:Winding wires.

33、 bonding layer: A material which is deposited on an enamelled wire and which hasthe specific function of bonding wires together.3.1.2 bunched wire: A winding wire consisting of a number of small diameter insulatedwires laid-up together without predetermined geometrical position and with or withoutad

34、ditional covering.3.1.3 class: The thermal performance of a wire expressed by the temperature index andthe heat shock temperature.851-1 IEC:1996 9 3.1.4 coating: A material which is deposited on a conductor or wire by suitable meansand then dried and/or cured.3.1.5 conductor: The bare metal after re

35、moval of the insulation.3.1.6 covering: A material which is wound, wrapped or braided around a bare orinsulated conductor.3.1.7 crack: An opening in the insulation which exposes the conductor to view at thestated magnification.3.1.8 dual coating: An insulation composed of two different materials, an

36、 underlyingand a superimposed coating.3.1.9 enamelled wire: A wire coated with an insulation of cured resin.3.1.10 grade: The range of increase in dimension of the wire due to insulation.3.1.11 insulation: A coating or covering of the conductor with the specific function ofwithstanding voltage.3.1.1

38、 General notes on methods of testUnless otherwise specified, all tests shall be carried out at a temperature from 15 Cto 35 C and a relative humidity of 45 % to 75 %. Before measurements are made,the specimens shall be preconditioned under these atmospheric conditions for a timesufficient to allow t

39、he wire to reach stability.The wire to be tested shall be removed from the packaging in such a way that the wire willnot be subjected to tension or to unnecessary bends. Before each test, sufficient wire shallbe discarded to ensure that any damaged wire is not included in the test specimens.Normally

40、, all mandatory requirements for a method of test are given in the description, anddiagrams are intended only to illustrate one possible arrangement for conducting the test.In case of inconsistencies between the specification sheet, IEC 317, and this standard, thespecification sheet shall prevail.85

41、1-1 IEC:1996 11 When the test is restricted only to certain types of winding wires, this is specified with thetest.Those tests of IEC 851-2, IEC 851-3, IEC 851-4, IEC 851-5 and IEC 851-6 which inannex A are marked with an asterisk are periodic conformance tests. These tests arecarried out upon reque
