The content ofboth the type and routine tests shall be agreed with the Transport Authority.This clause defines the requirements of both types of test which shall be performed on the braking system.Type tests shall be performed on an early production unit or train prior to any of that fleet of vehicles enteringservice and forms the basis of an acceptance of the brake system design and its implementation. Type testing ofrefurbished rolling stock shall be undertaken if the brake system has been modified or if the train mass and/orpassenger load has been significantly changed (see Section 1 of EN 13452-1:2003).The content of the type testing for refurbished stock shall be agreed with the Transport Authority, according to themodifications implemented. Routine tests shall be performed on every production unit or train prior to that trainentering service.4.2 Type test requirements4.2.1 Static type testsPrior to any static testing, all necessary system integration and constructional tests shall have been successfullycompleted.The principal objectives of these static type tests are to verify that the train’s braking equipment is compliant withthe specification and to establish the values of all the relevant parameters as a reference for assessing thedynamic performance.A full functional test, including all safety devices, shall have been satisfactorily completed before beginning thedynamic tests.Static type testing for the brake system may combine both bench tests and on-train tests. The scope of static typetesting shall include, but not be limited to, the following (where applicable or equivalents depending on the type ofbrake equipment):¾ brake cylinder pressures (or equivalent);¾ load-weigh signals (e.g. pressures);¾ friction pair loads (block force or pad clamping force);¾ brake actuator operation and stroke;¾ governor settings (e.g. pressure switches);SIST EN 13452-2:2004
EN 13452-2:2003 (E)7¾ brake application times;¾ brake release times;¾ monitoring device accuracy;¾ functionality e.g. correct operation of all controls and isolation devices at train / vehicle; component level;¾ interlock operation (e.g. traction inhibition in emergency braking);¾ brake stored energy capacity (e.g. brake reservoir volume);¾ leakage tests;¾ protection devices fitted to minimise the effects of failures (e.g. chokes, check valves);¾ WSP application / release times;¾ sanding system operation.In case particular parameters, e.g. brake application and release times, cannot be easily tested on certain vehicles,such tests may be undertaken as bench tests if agreed with the Transport Authority.The exact static testing undertaken depends on the design of the particular rolling stock.If more than one method of braking (e.g. friction brakes and track brakes) is used in any braking mode, then testsshall be conducted on each of these separately, so as to determine the functionality and response of each system.4.2.2 Dynamic type tests4.2.2.1 GeneralPrior to any dynamic testing, the static testing specified above shall have been completed. In addition any specifiedsimulation and/or bench testing (e.g. thermal predictions, WSP evaluation) shall have been completed.The purpose of dynamic brake testing is to demonstrate that the train performance complies as a minimum with therelevant requirements as contained in clause 6, 7, 8 or 9 of EN 13452-1:2003.NOTEThe operational performances defined in EN 13452-1 are based on theoretical values. In order to demonstratecompliance with the requirements defined in EN 13452-1 it is recommended to conduct tests and, from the results of these, todetermine if the values actually achieved fall within the limits defined in EN 13452-1.For any initial speed, in accordance with 5.5.1 of Part 1, the stopping distance for each test shall be less than orequal to the calculated value with a theoretical brake as defined with the ae and te specified in 3.7.2 and 3.7.3 ofEN 13452-1:2003 and in accordance with the relevant Table 3,7,11 or 15 of EN 13452-1:2003.In addition, the comfort limits defined by the relevant Table 4, 8, 12 or 16 of EN 13452-1:2003 shall not beexceeded during any of the tests.Additional tests shall be performed to demonstrate compliance with the brake performance specified by theTransport Authority to be achieved under defined brake failure conditions (refer to 5.6 of EN 13452-1:2003). It isrecommended that the failure conditions of one brake application system being defective (e.g. equipment inactiveor isolated) and the presence of unbedded components (e.g. brake blocks or pads) are considered by theTransport Authority.Additional tests shall also be conducted to establish the performance achieved under specified degradedenvironmental conditions (e.g. wet track). The Transport Authority shall define these conditions and the acceptancecriteria for these tests.SIST EN 13452-2:2004
EN 13452-2:2003 (E)8The Transport Authority may request investigative tests to establish the performance achieved under extremeconditions (e.g. ambient conditions, component temperature, passenger load, low adhesion, unfavourable wind ).In order to demonstrate consistent performance and ensure that the results are representative, a sufficient numberof tests shall be made.The performance obtained from different tests, done under nominally identical conditions, shall not diverge by morethan a defined value from the average performance for those test conditions (e.g. same speed, load, location,.),The Transport Authority shall define this figure (tolerance or repeatability band). It is recommended that this figuredoes not exceed ±10 % for dry rail condition. Furthermore, the consistency of performance between tests underdifferent conditions shall be assessed.The tests shall be conducted so as to avoid the risk of excessive temperatures being caused by any duty, in excessof the most severe operating conditions defined by the Transport Authority. Between tests, there shall be aminimum delay time or distance covered so as to ensure comparable initial conditions.4.2.2.2 Emergency brake - Type testingThe emergency brake testing shall be conducted at defined load and speed combinations. If more than one methodof braking (e.g. friction brakes and track brakes) is used in emergency braking, then tests shall be conducted for allcombinations of these, allowing for the possible failure or non-availability of any of these.The minimum number of type tests at each of the load conditions shall be either:¾ three tests each at three different speeds (total nine tests). The test speeds shall be uniformly distributedthrough the speed range or as otherwise defined by the Transport Authority, or¾ nine tests uniformly distributed through the speed range (one test at each of nine different speeds).The tests shall be done for a minimum of two load conditions covering the values defined in 6.3, 7.3, 8.3 or 9.3 ofEN 13452-1:2003, as appropriate. If not defined by the Transport Authority, the loads shall be EL E and EL 4 (LightRail and Regiona
