This European Standard shall be given the status of a national standard, either by publi
13、cation of an identical text or by endorsement, at the latest by October 2012, and conflicting national standards shall be withdrawn at the latest by October 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC

BS EN 13146-6:2012EN 13146-6:2012 (E) 4 Introduction This part of EN 13146 includes the only test procedure to find the effect of severe environmental conditions which is generally available at present. BS EN 13146-6:2012EN 13146-6:2012 (E) 5 1 Scope This European Standard speci
20、fies a laboratory test procedure for finding the effect of exposure to severe environmental conditions on the fastening system. This test procedure applies to a complete fastening assembly including embedded rail with mechanical fastenings. It is not applicable to embedded rail systems relying on ad
21、hesive components to secure the rail. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the re
22、ferenced document (including any amendments) applies. EN 13481-1:2012, Railway applications Track Performance requirements for fastening systems Part 1: Definitions EN ISO 9227, Corrosion tests in artificial atmospheres Salt spray tests (ISO 9227) 3 Terms and definitions For the purposes of this doc
23、ument, the terms and definitions given in EN 13481-1:2012 apply. 4 Principle The complete fastening assembly is exposed to a salt spray and the effect on ease of dismantling, and reassembly, and condition of individual components is recorded. 5 Apparatus 5.1 Salt spray equipment This shall conform w
24、ith EN ISO 9227 for the NSS (neutral salt spray) test. 5.2 Tools Manually operated tools normally used for installing and removing the clamping device from the fastening assembly. 6 Test specimens Each specimen shall consist of a complete fastening assembly with a baseplate or a section of sleeper,
25、bearer or element of slab track where no baseplate is used. This shall include a short length of rail of the section for which the fastening is designed. For fastening assemblies for embedded rail, the length of the test specimen shall be equal to the nominal sleeper spacing in EN 13481-1:2012, 3.1.
26、 BS EN 13146-6:2012EN 13146-6:2012 (E) 6 7 Procedure Visually examine and record the condition of each component. Then fit the rail to the section of sleeper or baseplate using the fastening components as they are to be assembled in track. Subject to the neutral salt spray in accordance with EN ISO
27、9227 for 300 h. Remove the clamping device using the tools provided; visually examine all the components and record their condition. Then reassemble the fastening system using the tools provided. Record any failure to dismantle or reassemble the fastening with the tools provided. 8 Test report The t
28、est report shall include at least the following information: a) number, date of issue and title of this European Standard; b) name and address of laboratory performing the test; c) date test performed; d) name, designation and description of fastening assembly, including individual components, teste
29、d; e) origin of test specimens; f) support used for assembly; g) rail section used in test; h) tools provided to assemble and dismantle the assembly; i) change in appearance (if any) of each component during test; j) any failure to dismantle or re-assemble the fastening assembly with the tools provi
