DIN EN 13146-8:2012-06 EN 13146-8:2012 (E) 4 Introduction As fastening syste
21、ms are safety critical, there is a need to have a standardized procedure to evaluate 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
22、a procedure which can be used to compare the performance in track of new or modified 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 th
23、e user. DIN EN 13146-8:2012-06 EN 13146-8:2012 (E) 5 1 Scope This European Standard specifies 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
24、-4:2012, EN 13481-5:2012 and EN 13481-7:2012. This test applies to complete fastening 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
25、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 referenced document (including any amendments) applies. EN 13146-9:2009, Railway applications Tra

27、 4 Principle The fastening system under test is installed in track at the same time as 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 a
28、nd service conditions. 5 Test conditions The performance of a fastening system, systems 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 o
29、r 200 sleepers each on metro systems or their equivalent for slab track. Installation 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 fast
30、ening system in a test shall be installed in track with similar conditions of formation, 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 sha
31、ll be consolidated mechanically, or by the passage of 1 105t (gross) traffic, prior to 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; DIN EN 13146-8:2012-06 EN 13146-8:20
32、12 (E) 6 weather conditions during installation. Rail used in the test shall be the same grade 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 susp
33、ended or supported in accordance with the normal practice of the user. During the test all 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 fo
34、llowing traffic to pass over the test track and shall be not less than 1 year. For category 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 fa
35、stening system shall be maintained in accordance with the manufacturers instructions. 6.3 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 sp
36、ecified intermediate stage and at the end of the test the following shall be measured or observed 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
37、 performance of signalling systems; d) clamping force, on not less than 10 assemblies, using 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 ins
38、tallation methods and weather during installation; g) security of attachment to the sleepers; h) condition of the rail head; i) condition of sleepers including rail seat area; DIN EN 13146-8:2012-06 EN 13146-8:2012 (E) 7 j) condition of individual fastening components; k) ease of assembly and remova
39、l using the tools recommended by the manufacturer. For items (d), (i), (j) and (k) not less than 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 incl
40、ude at least the following information: a) railway organization involved, location and dates of 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, inc
41、luding sleeper type, rail type, formation, ballast type and depth, gradient, curvature and cant; 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 o
42、f traffic; h) results of inspection and testing described in 6.3; i) an assessment of the performance 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.
