DIN EN 13231-4:2013-04 EN 13231-4:2013 (E) 4 1 Scope This European Standard lays down the technical requirements and the measurements to be made for the acceptance of work for reprofiling longitudinally
21、 and/or transversely the heads of railway rails in switches, crossings and expansion devices. For acceptance purposes two classes of longitudinal profile and three classes of transverse profile tolerance are defined. It applies to reprofiled vignole railway rails and associated switch rails 46 kg/m
22、and above. 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 referenced document (includin
23、g any amendments) applies. EN 13231-3:2012, Railway applications Track Acceptance of works Part 3: Acceptance of reprofiling rails in track 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13231-3:2012 apply. For the definitions of measurement instrume
24、nts also, see EN 13231-3:2012. 4 Longitudinal profile 4.1 Principle Measurements are made using either a reference instrument, or an approved instrument, see EN 13231-3:2012, Annex A or Annex B. The approved instruments shall be verified according to EN 13231-3:2012, Annex D. Approved instruments do
25、 not offer the same accuracy as reference instruments but are generally adequate for the purpose of demonstrating compliance with the requirements of this standard. NOTE An example of an approved instrument is the type of system used for routine measurements on reprofiling trains. Some of the system
26、s used for routine measurements on reprofiling trains fall into this category. In accordance with current practice, limits are set on the magnitude of the irregularities that can remain in track after a reprofiling operation. It is recognised, however, that it can be uneconomic to achieve 100 % comp
27、liance with these, particularly where isolated top faults, such as wheelburn, exist prior to reprofiling. Two classes are therefore offered, differentiated by the percentage of the reprofiled track meeting the specified criteria. Where isolated top faults exist, class 2 offers a lower cost option co
28、mpared to class 1 as it will be achieved with fewer passes. However a larger number of isolated non-compliant zones will remain in the reprofiled site. Class 1 also includes limits for very short (10 mm to 30 mm) and very long (300 mm to 1 000 mm) wavelength residual irregularities; these are not in
29、cluded in class 2. Where corrugations in these wavebands are required to be removed it will also be necessary to specify class 1. DIN EN 13231-4:2013-04 EN 13231-4:2013 (E) 5 4.2 Measurements required The longitudinal profile of the finished re-profiled rail in switches and crossings shall be record
30、ed either with machine mounted or manual measuring systems, either a reference instrument or an approved instrument. Where independent verification is required a reference instrument shall be used. All measurements undertaken in order to demonstrate compliance with 4.3 shall be recorded. Generally c
31、ontinuously working systems are to be used. In this case the rail containing the frog shall be measured only in “Zone G“, see Figure 1, the opposite rail shall be measured in the total ground length. If such a system is out of order or not available recording details shall be settled in the contract
32、. NOTE For measurements in the wavelength range (10 mm to 30 mm), at present it is unlikely that instruments other than reference instruments will have sufficient accuracy. Longitudinal profile measurements shall be made within a distance of 15 mm laterally on the rail from the rail crown for produc
33、ing the traced profile. It is recommended that a digital form of the traced profile, the primary profile, be used for subsequent analysis. The measurements can be undertaken immediately after work or at the latest within 8 days of reprofiling or after the track has carried 0,3 MGT (Million Gross Ton
34、s) of traffic. 4.3 Acceptance criteria for longitudinal profile 4.3.1 General The acceptance of reprofiled sites shall be on the basis of percentage of irregularities shown in Table 1. 4.3.2 Peak-to-peak value The percentage of any site in which the peak-to-peak value exceeds the value specified in
35、Table 1 shall be calculated. The primary or traced profile shall be processed to provide a filtered profile within each of the wavelength ranges given in Table 2. Table 1 Acceptance criteria for longitudinal profile expressed in terms of allowable percentages of exceeding for continuous measuring Wa
36、velength range (mm) 10 to 30 30 to 100 100 to 300 300 to 1 000 Class 1 5 % 5 % 5 % 5 % Class 2 No requirement 10 % 10 % No requirement Table 2 Acceptance criteria for peak-to-peak limits Wavelength range (mm) 10 to 30 30 to 100 100 to 300 300 to 1 000 Limit of peak-to-peak values (mm) 0,010 0,010 0,
37、015 0,075 The classification concerns the total length (Zones F, G and H in Figure 1) of the rail opposite the frog and Zone G only of the rail containing the frog. DIN EN 13231-4:2013-04 EN 13231-4:2013 (E) 6 No exceedances are allowed for manual measurements. 5 Transverse profile 5.1 Principle Mea
38、surements are made using either a reference instrument, see EN 13231-3:2012, 3.16 or an approved instrument, see EN 13231-3:2012, 3.2. Approved instruments do not offer the same accuracy as reference instruments but in general they are adequate for the purpose of demonstrating compliance with the re
39、quirements of this standard. Reprofiling can be undertaken for a variety of reasons. Where reprofiling is undertaken purely for the removal of corrugation, there may be less need for the rail to be reprofiled with precision. In other cases, it may be necessary for the reprofiled rail to match closel
40、y the ideal profile, represented by the reference rail, see EN 13231-3:2012, 3.22. A range of classes is therefore included to enable the client to specify the level of precision that is appropriate for the site to be reprofiled. NOTE Where reprofiling is undertaken to improve conicity, class Q, see
41、 5.4, is likely to be appropriate. The match between the reprofiled rail and the profile of the reference rail is determined by aligning the two at two points and measuring maximum difference between them, see EN 13231-3:2012, Figure 1. For straight track, these points of alignment generally approxi
42、mate to the highest point of the rail and the gauge point. On the high rail of curves this method is not applicable if side wear has occurred and an alternative method of alignment is therefore used. 5.2 Areas in crossings which are limited for reprofiling The areas where the switchblade touches sto
43、ck rail (Zone F shown in Figure 1) and the frog area (Zone H shown in Figure 1) cannot be reprofiled completely. The infrastructure manager can define applicable restrictions. 5.3 Measurements required The transverse profile of each finished, reprofiled rail shall be measured using either a referenc
44、e instrument or an approved instrument. Where independent verification is required a reference instrument shall be used, whereby measurements of each rail shall be made at an interval of not less than 10 m throughout the reprofiling site. A deviation of 0,1 mm between the reference instrument and ap
45、proved instrument would be acceptable according to EN 13231-3:2012, Annex B. All measurements undertaken in order to demonstrate compliance with 5.3 shall be recorded. The measurements can be undertaken immediately after work or at the latest within 8 days of reprofiling or after the track has carri
46、ed 0,3 MGT (Million Gross Tons) of traffic. NOTE It is preferable for measurements to be made immediately after re-profiling. After reprofiling rails in switches and crossings and rail expansion devices specific measurements are required for running safety. 5.4 Acceptance criteria for the transverse
47、 profile Each measured profile shall be aligned with the appropriate reference rail so that the reference points A and B1, or A and B2according to EN 13231-3:2012, Figure 1, on the reference rail coincide with points on the measured profile. The alignment shall be undertaken without rotation of eith
48、er profile. Reference points A and B2shall be used on side-worn rails and A and B1elsewhere. DIN EN 13231-4:2013-04 EN 13231-4:2013 (E) 7 The percentage of measurements in which the range of deviation is less than 0,6 mm, 1,0 mm and 1,7 mm shall be calculated and shall not be less than the values gi
49、ven in Table 3 for the class specified. When continuously working measurement systems are used the rail containing the frog shall be measured only in “Zone G“, see Figure 1, and only if this area is longer than 30 m. The opposite rail shall be measured in the total ground length. With spot-checks systems one recording per rail shall be made in front (measurement points 1 and 2) of the switch, one in the centre of the intermediate rail (measurement points 3 and 4 for the main track and - if applicable - measurement points 5
