Railway applications - Testing for the acceptance of running characteristics of railway vehicles - Freight wagons - Conditions for dispensation of freight wagons with defined characteristics from on-track tests according to EN 14363
This European Standard defines the process to determine the conditions under which dispensation from on-track testing according to EN 14363 can be given to freight wagons. In its application this document specifies the means by which dispensation from on-track tests is possible. This European Standard is subordinate to EN 14363. This European Standard is not limited to any type of freight vehicle; however certain types, which have been previously accepted under the auspices of UIC, are considered to have a continuing dispensation from on-track testing. These freight vehicles are detailed within this document. The dispensation conditions described in this document apply to all freight vehicles used in international, multilateral or national rail freight transportation, which operate without restriction on standard gauge tracks (1 435 mm). The various rail-inclinations used in Europe (1:20, 1:40 and 1:30) are covered by the conditions for dispensation. This European Standard only contains requirements for characteristics related to requirements for on-track tests specified in EN 14363.

EN 16235:2013 (E) 5 Introduction EN 14363 defines the requirements for railway vehicles with respect to running behaviour. The approval process in accordance with EN 14363, including the dispensation defined in this standard, is illustrated in normative Annex B (flow chart). It is recognised that experience has demonstrated that running gear fitted to wagons that operate safely can also be fitted to other wagons which are within certain design limits. These other wagons will also operate safely without the need to undergo on-track testing. This experience is based on the characteristics of track design, track maintenance and vehicle maintenance in the European network since 1998. This document defines the process to determine the conditions under which such dispensation from testing can be given for a vehicle defined by the running gear and its relevant parameters together with the associated parameter limits of wagon bodies. Vehicles for the transport of freight on the railway have historically been subject to standardisation. Very early common items like wheels, buffers, draw gear, etc. were developed as standardised components to fulfil safety requirements, for achieving ease of repair and maintenance for international traffic and low cost. Freight wagons have a wide range of applications and consequently the parameters will vary. In the UIC work for the standardisation and interchange of freight wagons certain processes for acceptance with respect to running characteristics evolved and these were formalised in UIC 432 and UIC 572 among others. The principles of this standard are similar to the intention of these two leaflets. NOTE Vehicles accepted through the UIC process were also accepted for RIV (Regolamento Internazionale Veicoli) service, i.e. international interchange between the RIV railways. This was replaced by the General Contract of Use for Wagons (GCU) agreement on 1st July 2006. Following the Directive 2008/57/EC the Conventional Rail Technical Specification for Interoperability for Freight Wagons (CR TSI WAG) was elaborated, which contains interoperability requirements for freight wagons. The following principles apply to the use of this standard: 1) The railway system requires comprehensive technical rules in order to ensure an acceptable interaction of vehicle and track. 2) New railway vehicles are approved (in the UIC 432 the term homologated is used) before being placed into service in accordance with numerous national and international regulations. In addition, existing approval is checked when operating conditions are extended. The approval is based on test results, calculations and/or comparisons with existing vehicles in order to achieve a safety level according to the recognised standards and regulations. 3) It is of particular importance that the existing level of safety and reliability is not compromised even when changes in design and operating practices are demanded. This standard does not prevent the use of the principles laid down applying to other types of rolling stock.
SIST EN 16235:2014EN 16235:2013 (E) 6 1 Scope This European Standard defines the process to determine the conditions under which dispensation from on-track testing according to EN 14363 can be given to freight wagons. In its application this document specifies the means by which dispensation from on-track tests is possible. This European Standard is subordinate to EN 14363. This European Standard is not limited to any type of freight vehicle; however certain types, which have been previously accepted under the auspices of UIC, are considered to have a continuing dispensation from on-track testing. These freight vehicles are detailed within this document. The dispensation conditions described in this document apply to all freight vehicles used in international, multilateral or national rail freight transportation, which operate without restriction on standard gauge tracks (1 435 mm). The various rail-inclinations used in Europe (1:20, 1:40 and 1:30) are covered by the conditions for dispensation. NOTE The test procedures described in this standard (and in EN 14363) can be applied also to applications with other track gauges e.g. 1 524 mm or 1 668 mm. The limit values could be different, as the details of such networks are not known by the authors of this standard. If established running gear are existing in such restricted networks the related ranges of running gear and vehicle parameters for dispensation from on-track tests might be specified together with the operational parameters (speed, cant deficiency, maximum axle load) based on previous tests and operating experiences. These limit values and parameters will be specified under national responsibility. This European Standard only contains requirements for characteristics related to requirements for on-track tests specified in EN 14363. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for the application of this document.

Then the influence on the assessment of the vehicle in terms of the acceptance criteria shall be evaluated and recorded. The outcome of this study shall be considered as an integral part of the requirements of this standard when applied to the assessment process of the vehicle. 5 Acceptance process to achieve a standardised running gear status 5.1 General Standardised running gear according to this standard shall be certified. For this purpose on-track tests according to EN 14363 (for axle loads above 22,5 t also according to EN 15687) shall be carried out with two different vehicles. If both vehicles pass the tests described in 5.2, the running gear shall be certified as standardised running gear in a 'declaration of conformity' with this standard that contains: a description of the standardised running gear; the relevant parameters and their proven range as specified in 5.3 and 5.4; the range of applicable parameters of the vehicle body as specified in 5.5; the applicable operating conditions. Vehicles with parameters within the range defined in the 'declaration of conformity' and equipped with a standardised running gear have dispensation from on-track testing according to EN 14363 (for axle loads above 22,5 t also according to EN 15687). The established running gear defined in Clause 6 of this standard shall be regarded as fulfilling the requirements of this chapter and the parameters specified in Clause 6 shall be regarded as equivalent to the 'declaration of conformity'. This procedure applies only to the on-track tests as required in the relevant clauses of EN 14363 (for axle loads above 22,5 t also according to EN 15687). It does not give approval for safety against derailment on twisted track (5.1) and under longitudinal compressive forces in S-shaped curves (5.2). 5.2 Test requirements 5.2.1 Extent of tests On-track tests shall be carried out according to the complete procedure specified in EN 14363 (for axle loads above 22,5 t also according to EN 15687). The tests shall be performed for the same intended operating conditions (Vadm and Iadm) with two wagons with different body parameters within the ranges defined in Table 1 as follows: one wagon of short running gear distance; and one wagon of long running gear distance. For the purposes of assessment of running behaviour in loaded condition, a typical loading condition shall be tested. NOTE 1 It is not necessary to test the worst position of centre of gravity (as it is in most cases impossible to have a density of the load, filling the whole loading gauge, that would lead to the maximum axle load).

In addition, 2 axle wagons for speeds ≥ 100 km/h shall be tested in loaded condition also in sections of test zone 2 with clearances given by a gauge ≥ 1 450 mm in combination with wheelsets having distances between active faces at the minimum operation limit.
If the design parameters and the operation parameters require the application of the normal measuring method, it is nevertheless acceptable to perform such tests with one of the vehicles based on measurements of lateral acceleration. In that case, it shall be demonstrated that a relationship exists between accelerations and the sum of the guiding forces on the vehicle tested according to the normal measuring method and a related limit value shall be established. NOTE 2 This requirement is an extension of the application of the simplified measuring method, using information gathered with vehicle tested according to the normal measuring method. NOTE 3 This requirement is intended to be transferred to the test conditions in EN 14363. 5.2.2 Certification The compliance of new types of bogies or running gear with the requirements of this standard shall be documented in the 'declaration of conformity' with this standard. This declaration shall include: an unequivocal and unique name for the running gear; range of parameters of the running gear (see 5.3); detailed technical description of the interface between vehicle body and running gear (see 5.4); range of parameters of car bodies to be used together with the running gear (see 5.5); wear limits which are essential to sustain an acceptable running behaviour (maintenance rules are outside the scope of this document). Examples for such information can be found in Annex C to Annex L, where these are given for already accepted running gear. 5.3 Range of running gear parameters for dispensation from on-track tests The functional details of the running gear relevant to the running behaviour during on-track tests according to EN 14363 (for axle loads above 22,5 t also according to EN 15687) shall be specified in the acceptance SIST EN 16235:2014
EN 16235:2013 (E) 11 process. Table 2 and Table 3 give an indication of which parameter shall be available for acceptance purposes. In addition the following shall be specified: admissible speed Vadm; admissible cant deficiency Iadm. Following successful testing according to 5.2 the acceptable parameter variation range for a dispensation from on-track tests for single-axle running gear and bogies is given by the range between the nominal tested parameters of the running gear and the extended range where specified in Table 2 and Table 3 for single-axle running gear and bogies. All parameters given in these tables are nominal values. The upper limit of the acceptable range depends on the maximum tested value of the respective parameter, the lower limit on the minimum tested value. Successful testing means that on-track tests according to EN 14363 (for axle loads above 22,5 t also according to EN 15687) showed compliance with the acceptance criteria given in these standards. To extend the applicable parameter range of a standardised running gear, test results of a third tested vehicle outside the previously tested range shall be used.
