This European Standard specifies the on-track testing for acceptance of the running characteristics of railway vehicles equipped with a cant deficiency compensation system and/or vehicles intended to operate with a higher cant deficiency than stated in EN 14363:2005, Annex G.
In most cases the procedure is the same as defined in EN 14363, only the differences for the special case are listed.
The testing of the running characteristics applies principally to all vehicles used in public transport which operate without restriction on standard gauge tracks (1 435 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 to be used under a vehicle body of another design, this is considered to be a design modification. The procedure as described in 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 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.
