This European Standard specifies the testing for acceptance of the running characteristics of freight vehicles with static axle loads higher than 225 kN and up to 250 kN. All requirements of EN 14363 are applicable with some adaptations concerning: the conditions of line tests; limit values for some assessment quantities. Only differences for the special cases are listed. The testing of the running characteristics applies principally to all freight vehicles, which operate without restriction on standard gauge tracks (1435 mm). NOTE 1 The testing of the running characteristics of: railways with different track layout, railways with non-standard gauge tracks can be conducted by analogy with this European Standard. The testing of running characteristics is part of the test for the acceptance of running characteristics of vehicles which are newly developed, have had relevant design modifications, or have changes in their operating regimes. The testing and acceptance of running characteristics refers to the complete vehicle including the running gear. If a running gear, which has already been tested and accepted, is used under a vehicle body of another design, this is considered a design modification. The procedure as described in EN 14363:2005, 5.2 is used. NOTE 2 In addition to the testing of running characteristics for the acceptance of vehicles, the regulations can be generally applied in other technical tasks, e. g.: the checking for compliance against development contracts; the optimization of components, vehicles or running gear; the testing of influences, influencing parameters and relationships of dependence; the monitoring of track or vehicles in operational use. The application of the full method and the stated limit values reflects unrestricted international operation. Testing for acceptance of vehicles is based on some reference conditions of track. If these are not respected on certain lines, appropriate measures will be taken (speed modifications, additional tests etc.). For national or multinational operations variations may be authorized from to the defined conditions. Permissible deviations are indicated in this European Standard. It is allowed to deviate from the rules laid down if evidence can be furnished that safety is at least the equivalent to that ensured by complying with these rules. NOTE 3 For vehicles other than freight wagons with static axle loads higher than 225 kN and up to 250 kN it is possible to use the limit values stated in this European Standard together with the specified track conditions and operational conditions as a basis for proof of the same safety level.
