24、al 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 this e
25、nd 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 National Com
26、mittee 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 (ISO) in
27、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 from al
28、l 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 held r
29、esponsible 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 diver
30、gence 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 Publication.
31、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, property dam
32、age 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 cited in this pub
33、lication. 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 identifying any or all
34、such patent rights. International Standard IEC 62499 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. It is based on EN 50405:2006. The text of this standard is based on the following documents: FDIS Report on voting 9/1190/FDIS 9/1218/RVD Full informati

37、COLLECTION SYSTEMS PANTOGRAPHS, TESTING METHODS FOR CARBON CONTACT STRIPS 1 Scope This International Standard gives rules for testing methods for carbon contact strips. The purpose of this standard is to demonstrate that the carbon contact strip construction, by attachment to integral supporting str
38、ucture (carrier) but excluding bolted assembly, is fit for purpose. Not all tests may be relevant to some designs. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated refer
39、ences, the latest edition of the referenced document (including any amendments) applies. None. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 carbon contact strip strip of carbon material, permanently attached to an integral supporting struc
40、ture (carrier) but excluding bolted assemblies 3.2 shear strength stress at failure of the adhesion between carbon and the support structure 3.3 autodrop detection sensor mechanism incorporated in the carbon contact strip to provide the indication for the pantograph automatic dropping device (ADD) 3
41、.4 flow continuity uninterrupted flow of air or other fluid 3.5 rated current loading current value defined by the manufacturer that the carbon strip is designed to sustain without degradation under the specified operating conditions 4 Symbols and abbreviations A designed area of adhesion (mm 2 ) F

The above tests are described in 5.1.1 to 5.1.2. Supplementary tests may be required if they have been specified in the customer specification
43、 and after agreement with the supplier. Annex A summarises the tests which shall be performed. 5.1.1 Type tests Type tests shall be performed on a single piece of product of a given design. Equipment in current manufacture shall be considered to have satisfied the type tests; if the manufacturer can
44、 provide certified reports of type tests already conducted on identical components, the type tests shall be considered to be complied with. 5.1.2 Routine tests Routine tests shall be carried out to verify that the properties of a product correspond to those measured during the type test. Routine tes
45、ts shall be performed by the supplier on each equipment. 5.2 Test procedures 5.2.1 Tests for the temperature characteristic of the carbon contact strip under rated current loading 5.2.1.1 General The test aims to determine the temperature characteristic to stability of the carbon contact strip at th
46、e maximum designed current loading. 5.2.1.2 Test method The carbon contact strip shall be fixed at one end and freely supported at the other end (see Figure 1). The current supply connection shall be made by clamping suitable interfaces to the vertical faces of the carbon, but not in contact with th
47、e carrier material (see Figure 2). The current take off shall be made at the normal design interface(s) between the carrier and the pantograph. 62499 IEC:2008 7 2 1 4 3 IEC 2191/08 Key 1 parallel clamp (steel) 2 carbon contact strip fixed end 3 temperature sensor 2 mm above carbon carrier interface
