Railway applications - Braking systems of high speed trains - Part 2: Test methods
This European Standard specifies test methods and acceptance criteria for a brake system for use in high speed trains as described in the TSI Rolling Stock, operating on routes of the trans-European high-speed rail system. The tests defined in this document have the purpose of verifying that the braking performance and functions of the train's brake system comply at least with the respective requirements of EN 15734-1. This European Standard is applicable to: new vehicles of high speed trains; new constructions of existing vehicle types; major overhauls of the above-mentioned vehicles if they involve redesigning or extensive alteration to the brake system of the vehicle concerned. The functional testing requirements set out in this document assume the vehicles are fitted with a brake system architecture that follows the UIC air brake pipe control principles. High Speed Rolling Stock can be fitted with alternative brake system architectures that do not employ brake pipe control. In these cases equivalent testing requirements will need to be generated to test the functional performance of brake system fitted.

The format shall enable an easy access to all the information associated to the tests. An example is attached in Annex A. NOTE If, for the routine tests, the vehicle manufacturer would like to use another way for recording the information (record, check), this will need the approval of the approval body.
5.2.7 Documentation The parameters as follows shall be recorded irrespective from the type of testing: software versions of all brake-relevant components (all software-controlled systems, contributing directly or indirectly to the braking performance: drive units, anti-skid protection systems, brake modules, etc.); batch numbers of the friction materials (blocks, inserts, pads, etc.) and results of bench tests in dry and wet conditions; brake cylinder pressures in the case of an emergency brake application for at least one motor bogie and one trailer bogie; wheel diameter. It is assumed that the documentation conforms to the relevant standards and that conformity with these requirements shall be established before performing the tests. 5.3 Methodology 5.3.1 Measurement of the application time at the brake cylinder The application time is to be measured from 0 % to 95 % of the maximum stabilized pressure at the brake cylinder. This is measured at the brake cylinder which is the furthest from of the brake panel which controls it. It is accepted to add a T-connection for the type test. SIST EN 15734-2:2011
EN 15734-2:2010 (E) 11 5.3.2 Measurement of the release time at the brake cylinder The release time is to be measured from the maximum stabilized pressure at the brake cylinder down to 0,4 bar. This is measured at the brake cylinder furthest from the brake panel which controls it. It is accepted to add a T-connection for the type test. However for the routine tests of the stocks equipped with variable load relay valves, it is usual to measure at the distributor’s brake cylinder pilot pressure. In any case, the full release at the brake cylinder shall be verified. 5.3.3 Measurement of the pressure drop time in the brake pipe or the equalising reservoir of the driver’s brake valve The pressure drop time is to be measured from 5 bar to 3,5 bar, but the pressure drop to be done is to be from 5 bar to 3,2 bar. 5.3.4 Measurement of the pressure rise time in the brake pipe or the equalising reservoir of the driver brake valve The pressure rise time is to be measured from 3,5 bar to 4,9 bar. 5.3.5 Measurement of the dead time of the WSP dump valves The dead time for exhaust and fill is to be measured from the command to fill or release to the start of the pressure variation at the brake cylinder. This is measured at the brake cylinder which is furthest away from the dump valve which controls it. It is accepted to add a T-connection for the type test. 5.3.6 Measurement of the exhaust time of the WSP dump valves The exhaust time is to be measured from the maximum stabilized pressure at the brake cylinder down to 0,4 bar. This is measured at the brake cylinder of the vehicle which is furthest away from the dump valve which controls it. It is accepted to add a T-connection for the type test. 5.3.7 Measurement of the fill time of the WSP dump valves The fill time is to be measured from 0 % to 95 % of the maximum stabilized pressure at the brake cylinder. This is measured at the brake cylinder of the vehicle which is furthest away from the dump valve which controls it. 5.3.8 Measurement of air tightness When carrying out pressure leakage tests, waiting time shall be at least 1 min for pressure stabilisation before starting timing measurements.
5.3.9 Measurement of lowering time of the MTB The lowering time of the MTB shall be measured between the activation command and the impact of the magnets on the rail.
5.3.10 Measurement of rising time of the MTB The rising time of the MTB shall be measured between the deactivation command and reaching their upper position.
SIST EN 15734-2:2011
EN 15734-2:2010 (E) 12 5.3.11 Measurement of application and release times of EP assist brake The times shall be checked on an individual vehicle with the compressed air brakes applied, with the BP first being pressurized to 5 bar and then shut off. The times shall be calculated when the electrical signal is established to the braking or release solenoid valve. During ep braking, the application time shall be measured decreasing the BP pressure from 5 bar to 3,5 bar. During ep release, the release time shall be measured increasing the BP pressure from 3,5 bar to 4,9 bar with an auxiliary air reservoir pressure of 5,3 bar to 5,5 bar.
5.3.12 Measurement of the contribution of the different brakes During dynamic tests the contribution of the different brakes installed on the rolling stock shall be measured as follows: for the friction brake by recording the pressure in the brake cylinders; for the dynamic brake by recording the brake force information provided by the traction equipment; for the eddy current brake by recording the brake force information provided by the control equipment; for the magnetic track brake by recording their state and using design data. 5.3.13 Evaluation of the longitudinal brake force applied to the track by Magnetic Track Brake or Eddy Current Brake The longitudinal force shall be evaluated for emergency brake application and if applicable also for full service brake application from maximum speed under operational mass in working order. If there a load dependent brake force is applied for the Eddy Current Brake, then the design mass under exceptional payload shall also be considered. The longitudinal force for the magnetic track brake shall be calculated from the deceleration which is raised by the Magnetic track brake. These deceleration shall be calculated as the difference between the deceleration which is measured for brake applications with and without acting Magnetic Track Brake. For the Eddy Current Brake the recorded brake force information provided by the control equipment shall be evaluated. SIST EN 15734-2:2011
