BS EN 50405:2015+A1:2016 EN 50405:2015+A1:2016 (E) 5 Introduction This European Standard defines testing methods for p
32、antograph contact strips, but excludes wear tests, and tests using a particular pantograph. In this issue of the standard, additional clauses have been included to address the European Rail Agency (ERA) request for standard (IU-RFS-024 of 3rd July 2009) which requested that this standard specifies t
33、he assessment methods for contact strips of different materials as specified in the High Speed and Conventional Rail Locomotives and Passenger rolling-stock technical specifications for interoperability (LOC and PAS TSIs). A method for determining the metal content for metal impregnated (metalized)
34、contact strips (7.8) has been added in this issue of the standard. Tests for the coefficient of friction (7.9) and impact resistance of the carbon material (7.10) have also been included in this revision. The Locomotives and Passenger rolling-stock technical specification for interoperability (COMMI
35、SSION REGULATION (EU) No 1302/2014 of 18 November 2014) (LOC and PAS TSI) chapter 4.2.8.2.9.4.2 states: 4.2.8.2.9.4.2 Contact strip material (1) Material used for the contact strips shall be mechanically and electrically compatible with the contact wire material (as specified in Clause 4.2.14 of the
36、 ENE TSI, in order to ensure proper current collection and to avoid excessive abrasion of the surface of the contact wires, thereby minimising wear of both contact wires and contact strips. (2) Plain carbon or impregnated carbon with additive material shall be permitted. Where a metallic additive ma
37、terial is used, the metallic content of the carbon contact strips shall be copper or copper alloy and shall not exceed a content of 35 % by weight where used on AC lines and of 40 % where used on DC lines. Pantographs assessed against this TSI shall be fitted with contact strips of a material mentio
38、ned above. (3) Additionally, contact strips of other material or higher percentage of metallic contents or impregnated carbon with cladded copper are allowed (if permitted in the infrastructure register) provided that: they are referenced in recognised standards, with mention of restrictions if any,
39、 or they have been subject to a test of suitability for use (see 6.1.3.8). Evidence from the UIC project “COSTRIM” testing of a sample of carbon contact strips has shown the difficulty of defining a cross-industry wear test. This could be the subject of a new requirement following further analysis o
40、f the COSTRIM results for a future revision of this standard. (These values were determined as a result of the tests undertaken under the COSTRIM project, and are the limit of the tests carried out, rather than an absolute limit.) Although not currently applicable to contact strips for railway appli
41、cations, it should be noted that certain materials listed in the EU Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment 2011/65/EU are prohibited from use in certain applications BS EN 50405:2015+A1:2016 EN 50405:2015+A1:2016 (E) 6 1 Scope T
42、his European Standard specifies testing methods to establish the basic characteristics of newly manufactured pantograph contact strips. Not all tests may be relevant to some designs of contact strips. This standard does not define tests for pure metallic contact strips. This European Standard exclud
43、es wear tests, and tests using a particular pantograph. Additional supplementary tests, out of the scope of this standard, may be necessary to determine suitability for a particular application and are by prior agreement between customer and manufacturer. 2 Normative references The following documen
