14、lectrotechnical 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 fiel
15、ds. To 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
16、 National 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 Standardizat
17、ion (ISO) 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 represent
18、ation from 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 can
19、not 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 Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publicatio
20、ns. 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 procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC
21、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 or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury,
22、 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 drawn to the Normative references cite
23、d 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 not be held responsible for identifyin
24、g any or all such patent rights.

29、rt 3: Equipment wires with solid or stranded conductor wires, PVC insulated, in singles, pairs and triples 1 Scope This part of IEC 60189 is applicable to equipment wires with solid or stranded conductor, polyvinyl chloride (PVC) insulated, in singles, pairs and triples to be used for internal wirin
30、g of telecommunication equipment, industrial and consumer electronic equipment. NOTE It is the responsibility of the manufacturer to establish quality assurance by quality control procedures which will ensure that the product will meet the requirements of this standard. It is not intended that a com
31、plete testing programme must be carried out on every length of conductor. When the purchaser wishes to specify acceptance tests or other quality procedures, it is essential that agreement be reached between the purchaser and the manufacturer by the time of ordering. 2 Normative references The follow

35、construction and dimensions 4.1 Conductor 4.1.1 Conductor material The conductor shall consist of annealed copper, uniform in quality and free from defects. The properties of the copper shall be in accordance with IEC 60028. 6 60189-3 IEC:2007(E) The three smallest conductors (0,12 mm and 0,15 mm di
36、ameter and 0,035 mm 2cross- sectional area) shall consist of copper alloy, uniform in quality and free from defects. Copper alloy may also be used for other small conductor gauges. 4.1.2 Type of conductor The conductor may be either solid or stranded. The solid conductor shall consist of a single st
37、rand circular in section. This stranded conductor shall consist of several strands of circular cross-section assembled either by concentric layer stranding or by bunching, and without insulation between them. 4.1.3 Conductor finish The conductor may be either plain or tinned. 4.1.4 Conductor dimensi
38、ons The solid conductor is designated by its nominal diameter. This stranded conductor is designated by its nominal cross-sectional area, the number of strands, and maximum diameter of strands. Dimensions are given in Annexes A and B. 4.1.5 Continuity of conductor Normally the conductor shall be dra
39、wn in one piece. In cases of necessity, joints in the conductor are permitted provided that the breaking strength of a joint is not less than 85 % of the breaking strength of the unjointed conductor. Joints in a complete stranded conductor are not permitted. 4.2 Insulation 4.2.1 insulation material
40、The insulation shall consist of PVC. NOTE The initials “PVC“ denote a plasticized compound of polyvinyl chloride or vinylchloride-vinylacetate copolymers. 4.2.2 Insulation thickness The insulation shall be continuous having a thickness as uniform as possible and not less than the value specified in
41、Annex A. The maximum diameter of the wire shall be calculated in accordance with the method given in Annex C. The minimum thickness of the insulation shall be measured in accordance with the method specified in 5.2.1.1 of IEC 60189-1. 4.2.3 Application of the insulation The insulation shall be appli
42、ed to fit closely to the conductor without adhering to it. 60189-3 IEC:2007(E) 7 The stripping properties of the insulation shall be checked in accordance with the method specified in 6.4.2 of IEC 60189-1. It shall be possible to strip the insulation from the conductor easily and without damage to t
43、he insulation, to the conductor, or to the tinning, if any. 4.2.4 Colour of insulation The insulated conductors shall be coloured by one colour or by two different colours. Colours shall correspond reasonably with the standard colours shown in IEC 60304. Colour fastness to daylight, checked accordin
44、g to ISO 105, shall be rated at not less than standard 4, prolonging the exposure until the contrast is equivalent to grade 4 on the grey scale. When two colours are used, the following conditions shall be fulfilled: markings shall be rings or helices; if helices, single helices are preferred, doubl
45、e helices, however, are allowed; markings may be made by helical bicolour extrusion; markings printed or painted on the insulation shall adhere satisfactorily; markings shall be easily identifiable within any 15 mm length of the insulated conductor; the distance of repetition of the markings shall b
46、e not less than 4 mm, measured from centre to centre parallel to the axis; the width of the rings or helices and the width of their spacing shall be not less than 1,5 mm, measured parallel to the axis; the widths shall be approximately constant along the insulated conductor; the width of the rings o
47、r helices need not be the same as that of the spacing. NOTE For wires identified by ring marking, neither the registration of the two half-bands nor the complete encirclement of the wire is critical. The choice of colours or combinations of colours shall be made in the following order of preference:
48、 the 12 standard colours shown in IEC 60304; the following 19 easily identifiable combinations of two standard colours: RED-black RED-blue ORANGE-green ORANGE-blue ORANGE-violet YELLOW-black YELLOW-red YELLOW-green YELLOW-blue YELLOW-violet GREEN-black GREEN-red BLUE-black GREY-red GREY-blue WH ITE-
