23、 has been prepared by Technical Committee CEN/TC 256 “Railway applications “, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2012, and conflicting

24、 national standards shall be withdrawn at the latest by October 2012.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 shall not be held responsible for identifying any or all such patent rights. This document su

25、persedes EN 13146-5:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. The main changes in this revision are as follows: a) reference and alternative methods are now included; b) the conductivity of the water used in

26、 the test is limited; c) conditioning of the test specimens; d) the correction factor for water conductivity is deleted. In consequence of these changes, the measured resistance may be significantly different from that obtained by the previous method. This European Standard is one of the series EN 1

27、3146 “Railway applications Track Test methods for fastening systems“ which consists of the following parts: Part 1: Determination of longitudinal rail restraint; Part 2: Determination of torsional resistance; Part 3: Determination of attenuation of impact loads; Part 4: Effect of repeated loading; P

EN 13146-5:2012 (E) 5 1 Scope This European Standard specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of slab track. I

35、t is also applicable to embedded rail. This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to traction currents. A reference procedure and an alternative procedure are included. 2 Normative references The following documents, in whole or in part,

36、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 27888, Water quality Determination of electrical c

R measured resistance for each test, in ; R arithmetic mean of test results, in ; conductivity of water used, in mS/m. 4 Principle The electrical resistance between two short lengths of rail fastened to

39、 the support is measured whilst the whole support and fastenings are sprayed with water at a controlled rate. 5 Apparatus 5.1 Rail For surface mounted rail systems, two short lengths (approximately 0,5 m) of the section for which the fastening assembly under test is designed. For embedded rail syste

40、ms the rail is BS EN 131465:2012EN 13146-5:2012 (E) 6 included in the test specimen. The rail shall be unlaminated and have neither loose rust on the surface nor be polished on the foot. 5.2 Water A supply of potable water supply with a conductivity of (50 5) mS/m measured in accordance with EN 2788

41、8 at the temperature at the time of spraying and corrected to a temperature of 25 C. NOTE 1 Correction factors for temperature are given in EN 27888. NOTE 2 The conductivity of the water may be adjusted to the specified limits by the addition of sodium chloride or distilled water. 5.3 Spray equipmen

42、t A frame which can be moved parallel to the rails, incorporating four spray nozzles as shown in Figure 1. The nozzles shall have a diameter 3,6 mm and a spray cone of (100 to 125). The equipment shall include a means of controlling and measuring the flow of water to each nozzle. 5.4 Electricity sup

43、ply Alternating current supply of (30 3) V RMS and (50 15) Hz. 5.5 Instruments Instruments to measure the applied voltage and resultant current flow between the rails with an accuracy of 1 % which permit the calculation of resistance over the range 1 102 to 1 106. The equipment shall have a capabili

44、ty to print out a record of calculated resistance against time. The calibration of the instruments shall be verified with equipment having certified traceability to European or International Standards using the International System of units (SI). null 5.6 Water collection and re-cycling equipment Wa

45、ter sprayed onto the sleeper and fastening assemblies may be collected and re-cycled through the test rig, provided that the conductivity and temperature are maintained within the limits set out in 5.2. If such a procedure is used it is important to ensure that the entire water circulation system is

46、 designed to prevent collection of stagnant water and that the system is flushed through with clean water regularly. Failure to do this can lead to the creation of conditions in which harmful bacteria (e.g. Legionella) collect and breed in the test rig. NOTE Guidance on the control of Legionella in
