2、n Dec 24 04:33:02 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 50405:2006 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 November 2006 BSI 2006 ISBN 0 580 49613 9 National foreword This British Standard was published by BSI. It is the
3、 UK implementation of EN 50405:2006. The UK participation in its preparation was entrusted by Technical Committee GEL/9, Railway electrotechnical applications, to Subcommittee GEL/9/2, Rolling stock. A list of organizations represented on GEL/9/2 can be obtained on request to its secretary. This pub
4、lication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. WARNING This European Standard provides specifications for a number of standardized te
5、sts for the characteristics and integrity of pantograph carbon contact strips. It should be noted however, that no specific acceptance criteria are specified for passing the tests other than the requirement for shear strength. In some cases the acceptance criteria is specified as remaining “fit for
6、purpose” and this term is not defined in the standard. It is the opinion of UK committee GEL/9/2 that none of the tests included in this standard will demonstrate the resistance to impact and wear properties of the carbon strip under test. This standard does not provide the ability to compare grades
7、 of carbon. GEL/9/2 advises that users should ensure that where necessary, values to be achieved are specified prior to use of the standard as part of a contract, or, if the users own requirements are not to be stated, ensure that what is being procured is consistent with the application intended. G
8、EL/9/2 is of the opinion that compliance with this standard alone will not necessarily ensure that contact strips are suitable for the purpose intended. Amendments issued since publication Amd.
