IEC 62499:2008

Railway applications - Current collection systems - Pantographs, testing methods for carbon contact strips

IEC 62499:2008 gives rules for testing methods for carbon contact strips. The purpose is to demonstrate that the carbon contact strip construction, by attachment to integral supporting structure (carrier) but excluding bolted assembly, is fit for purpose.

Applications ferroviaires - Systèmes de captage du courant - Méthodes d'essais des bandes de frottement en carbone des pantographes

La CEI 62499:2008 donne les règles à suivre pour les méthodes d'essai pour les bandes de frottement en carbone. Le but de cette norme est de démontrer que l'emploi de bandes en carbone, attachées de façon permanente à une structure autoporteuse (étrier) à l'exclusion des ensembles boulonnés, est adapté à l'usage.

FOREWORD
1) The International Electrotechnical 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 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 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 Standardization (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 representation 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 cannot 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 publications. 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 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, 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 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 not be held responsible for identifying any or all 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 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.

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 structure (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 references, 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 structure (carrier) but
excluding bolted assemblies
3.2
shear strength
stress at failure of the adhesion between carbon and the support structure
