BS EN 13146-8:2012EN 13146-8:2012 (E) 4 Introduction As fastening systems are safety critical, there is a need to have a standardized procedure to eval
19、uate their performance in normal use. Performance in track is not always completely predicted from the laboratory tests in EN 13146, Parts 1 to 7 and 9. The test described in this part of EN 13146 is intended to provide a procedure which can be used to compare the performance in track of new or modi
20、fied fastening systems with systems whose performance is known. In accordance with EN 13481-2:2012, EN 13481-3:2012, EN 13481-4:2012, EN 13481-5:2012 and EN 13481-7:2012, this test has to be performed when required by the user. BS EN 13146-8:2012EN 13146-8:2012 (E) 5 1 Scope This European Standard s
21、pecifies a procedure for the comparative testing of fastening systems in track. The test procedure is applicable to fastening systems which in all other respects conform to EN 13481-2:2012, EN 13481-3:2012, EN 13481-4:2012, EN 13481-5:2012 and EN 13481-7:2012. This test applies to complete fastening
22、 assemblies. It is only used for comparative testing of such fastening systems installed at the same time on the type of support for which they are intended. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
23、 application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

24、012, Railway applications Track Performance requirements for fastening systems Part 1: Definitions 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13481-1:2012 apply. 4 Principle The fastening system under test is installed in track at the same time a
25、s a reference fastening system, on sleepers, bearers or slab track of the same material and design. Location in track is arranged so that the test and reference fastening systems are in track with similar geometry and service conditions. 5 Test conditions The performance of a fastening system, syste
26、ms or variants of a system under test shall be compared with a reference fastening system. Test and reference fastening systems shall be installed in one track in lengths containing not less than 500 sleepers each or 200 sleepers each on metro systems or their equivalent for slab track. Installation
27、 shall be within a period not exceeding 7 days. All fastening systems in any test shall be installed on the type of sleeper for which they are designed and only one type of sleeper shall be used in a test. Each fastening system in a test shall be installed in track with similar conditions of formati
28、on, ballast support, curvature, gradient and cant, and with similar traffic conditions including traffic volume, type, speed, braking and acceleration. If installation has involved a change in sleepers the track shall be consolidated mechanically, or by the passage of 1 105t (gross) traffic, prior t
29、o commencement of the test. The following shall be recorded. method of installing sleepers, bearers or slab; method of installing fastening components; method of installing rail; BS EN 13146-8:2012EN 13146-8:2012 (E) 6 weather conditions during installation. Rail used in the test shall be the same g
30、rade and section for the whole test length. The head shall be free of defects and consistent throughout the test lengths, and the foot shall be smooth on its underside. Any welded or bolted joints shall be suspended or supported in accordance with the normal practice of the user. During the test all
31、 mechanical joints shall be properly maintained. All track maintenance of the test lengths shall be done concurrently. 6 Procedure 6.1 Duration of test The minimum test period shall be that necessary for the following traffic to pass over the test track and shall be not less than 1 year. For categor
32、y A and B fastening systems 10 106t (gross) For category C, D and E fastening systems 20 106t (gross) NOTE Categories of fastening systems are defined in EN 13481-1:2012. 6.2 Maintenance During the test each fastening system shall be maintained in accordance with the manufacturers instructions. 6.3
33、Inspection Prior to the commencement of measurements, behaviour of the fastening system shall be visually observed and recorded during installation and consolidation of the track. At the commencement, at any specified intermediate stage and at the end of the test the following shall be measured or o
34、bserved for all systems being tested, including the reference system: a) track gauge; b) longitudinal movement of rail, relative to the sleeper or slab support, and maximum daily temperature range; c) effect on performance of signalling systems; d) clamping force, on not less than 10 assemblies, usi
35、ng the manufacturers recommended test method for use in track; e) rail pad static stiffness on not less than 10 pads, if required by the purchaser, measured in accordance with EN 13146-9:2009; f) details of installation methods and weather during installation; g) security of attachment to the sleepe

For items (d), (i), (j) and (k) not less tha
37、n 2 % of the assemblies shall be selected at random for examination. The assemblies selected shall be the same each time the measurement or observation is repeated. 7 Test report The test report shall include at least the following information: a) railway organization involved, location and dates of
38、 test; b) description of the fastening system including manufacturers designation; c) description and manufacturers designation of reference fastening system; d) details of the track used for the test, including sleeper type, rail type, formation, ballast type and depth, gradient, curvature and cant
39、; e) rail pad static stiffness on not less than 10 pads, if required by the purchaser; f) details of installation methods and weather during installation; g) duration of test, type and quantity and speed of traffic; h) results of inspection and testing described in 6.3; i) an assessment of the perfo
40、rmance of the fastening system under test relative to the reference fastening system; j) maintenance record of the track and the fastening assembly during test period.
