Les essais statiques sont les essais préliminaires effectués lorsque les véhicules et/ou le train sont à l'arrêt afin de permettre l'homologation d'un véhicule ferroviaire avant sa mise en service. Il est possible que des déplacements de véhicule se produisent pendant l’essai (par exemple au cours d’essais de frein de stationnement ou d’essais de capteur de vitesse d’essieu).
Les essais dynamiques forment une partie des procédures de mise en service d’un véhicule ; ces essais sont effectués en ligne. Ils sont décrits dans les spécifications particulières.
Les essais associés à la production d'énergie ne sont pas inclus dans le domaine d'application de la présente norme. (voir par exemple l’ISO 8573-1:2001).
La présente Norme européenne est applicable à :
tous les véhicules de conception nouvelle ;
toutes les remises à niveau majeures de véhicules lorsque celles-ci incluent des modifications importantes ou une reconception, susceptibles d’avoir une influence sur le système de freinage ;
toute nouvelle construction de véhicules sur conception déjà définie ;
tout démontage et remontage du système ou certaines parties de celui-ci.
Les systèmes de freinage pris en compte comprennent les composants et sous-systèmes suivants :
les distributeurs (voir le prEN 15355) ;

With a pre-serial unit or first vehicle/train of a serial production, type tests shall demonstrate that the brake system complies with the requirements. After successful passing of the type tests, routine tests shall confirm the technical stability of the production process of the system and its subsystems on subsequent trains following manufacture or modification as applicable. For this purpose, the final design of the system and its subsystems defined during the type test shall be considered. Brake testing shall also be undertaken if the brake system, and/or any other part of the train (e.g. train mass and/or load carried) has been changed from the final approved design referring to type test. (e.g. change of pad quality, shape). For example, this may be achieved by adjusting the settings of the existing brake equipment or installing new equipment, etc.
The content of this type testing, due to a brake design change, shall be agreed according to the modifications implemented. Before carrying out these tests, the following conditions shall be assured: The train brake system has been assembled according to the manufacturer’s design specifications; All system integration tests that could be carried out in advance of physical fitment of the brake system components to the vehicle/train to confirm their satisfactory interaction have been successfully carried out; All necessary component type / routine tests shall have been successfully completed. A non exhaustive list of brake components is given in Annex A. Tests associated with energy production (see ISO 8573-1) are supposed to be performed before beginning the static test on the train. SIST EN 15806:2010
EN 15806:2010 (E) 8 If more than one brake equipment type is used, the tests shall be conducted on each of these separately and in the used combinations to determine the functionality and response time of each single and combined equipment.
Where interactions between components and or subsystems has not been reliably verified by carrying out bench testing, these interactions shall be verified by testing after they have been integrated on the vehicle concerned. 5.1.2 Type test Where type tests are deemed necessary they shall be performed on a vehicle or train considered representative of the remainder of the fleet or build of vehicles or trains that use the same type designation. These tests shall take place prior to any of that fleet or build of vehicles entering service and they form the basis of an acceptance of the brake system design. The principal objectives of these type tests are to verify that the train’s braking system and equipment complies with the requirements of brake system specifications and to establish the values of all the relevant parameters as a reference for assessing the dynamic performance. If a multiple unit operation is required in the brake system specification, a static test shall be performed with a single unit and the longest multiple unit composition. Where interactions between components and or subsystems has not been reliably verified by carrying out bench testing, these interactions shall be verified by testing after they have been integrated on the vehicle concerned. 5.1.3 Routine tests Routine tests are to be carried out on every vehicle to verify conformance with the type-tested vehicle/train. The principal objective of the routine tests is to verify that each train’s braking equipment is consistent with that of the type tested train. All routine tests shall be completed successfully prior to the introduction of that unit or train into service. 5.2 General environmental conditions The brake system and braking equipment shall be tested within the ranges of conditions as specified in EN 50125-1.
5.3 Table of tests Table 1 lists the static tests that shall be carried out for all brake systems unless the nature of the brake system concerned is such that certain tests are not applicable (e.g. electrical tests for systems that do not use electricity as a control or power medium).
The Table 1 identifies the individual tests as stated in 5.4 and whether these tests should be conducted as part of type or routine tests conducted on an individual vehicle or train as applicable. The actual test sequence is at the discretion of the relevant test engineer. NOTE The applicability of the tests should be agreed between the stakeholders involved. These tests describe the minimum requirements for a static test. Braking energy supply sub-systems are those systems used to store and distribute the energy subsequently converted into a force for retarding the train. These sub-systems include main compressors, auxiliary compressors, hydraulic pumps, accumulators, reservoirs, battery charging, auxiliary generators, etc. They are only considered insofar as the interaction they have with the brake system (e.g. the quantity of energy required from these sub-systems as a function of time). Braking energy supply may also be used for communicating the braking application and release commands.

EN 15806:2010 (E) 9 The first three columns on the left in Table 1 describe the tests in terms of functions and what should be checked, and not the order of the tests and not how to proceed. The tests described are not exhaustive. In the two right hand columns the crosses (X) indicate the type tests and routine tests normally carried out. The final content of the type tests and routine tests depend on the status of the train or individual vehicle and/or brake system (e.g. new or modified).

5.4 Tests conditions and test requirements 5.4.1 General The following subclauses describe in more detail the tests listed in the Table 1. As a minimum, the following tests shall be conducted at various load conditions of the vehicle/train. The definition of the load conditions to be used is as contained in EN 15663. Vehicles without load dependant brake control shall be tested in state "operational mass, in working order". Herein after referred to as “empty” for the purpose of this standard. Vehicles equipped with a load dependant brake control shall be tested in the states "operational mass in working order" and "design mass under exceptional payload". Herein after referred to as “loaded” for the purpose of this standard. Load conditions may be simulated using mass dummies or equivalent means for obtaining the required load per unit area. Alternatively, and in the case of intermediate load conditions, loading can be simulated by using other methods, for example, by reproducing the load/weigh signal input to the brake control system, using an independent pressure regulator, or mechanically pressing on the primary suspension. NOTE The number of intermediate conditions of loads should be defined by the brake system specification. 5.4.2 Availability of energy supply 5.4.2.1 General The energy supply systems for pneumatic, hydraulic and electrical equipment shall be tested separately as applicable. The following tests, mentioned in 5.4.2.2 and 5.4.2.3, cover the different functional interfaces between the braking system and the energy supply systems. SIST EN 15806:2010
EN 15806:2010 (E) 11 5.4.2.2 Energy delivery and storage 5.4.2.2.1 General The vehicle and/or train to be tested shall be prepared so that it is in a state of readiness for service (e.g. all isolating devices are in their running positions) and with the applicable system/equipment load and working conditions (e.g. compressor motor electrical supply voltage, diesel engine operating at idle speed) as defined in the brake system specifications. Ordinarily these tests are carried out with the vehicle/ train in the tare condition. The relevant pressures and signals shall be measured and recorded during the tests according to the brake system specification. 5.4.2.2.2 Charging test For air/hydraulic systems a pump up test (energy charging test) shall be performed whilst observing pressures and times until such time as the system is fully pressurised and the compressors/pumps have stopped delivering energy.
The time achieved to put the vehicle in a pressure or energy state, such that from a brake system status point of view the vehicle/train is “ready to be driven”, shall be recorded. Ready to be driven is typically identified for example by the achievement of a minimum pressure in the brake supply reservoir, or other brake energy level, to ensure that full brake applications can be achieved prior to the vehicle being driven. The charging of the systems shall be continued noting the time at which the full system pressure is achieved, as signalled by the stopping of the relevant compressor/pumps. 5.4.2.2.3 Safety test Protection against overload of energy storage shall be checked by means described in the test procedure. 5.4.2.2.4 Energy supply control Energy consumption shall be simulated to check that the compressor/pumps management automatically maintains the specified service pressure.
An energy user shall be introduced in the system such that the air/hydraulic system is observed to replenish the energy system pressure to maintain the required energy status. 5.4.2.2.5 Successive applications of the brake (inexhaustibility) Commencing with the specified working pressures for the pneumatic energy supply the specified number of successive application (of the emergency or full service brake dependant on the brake system specification) shall be carried out, and it shall be confirmed that the pressures in the brake cylinder and other braking equipment including magnetic track brake lowering cylinders if applicable, are within the range defined in the brake system specification. 5.4.2.2.6 Electrical supply test The electrical energy supply for electro-pneumatic, electric braking (e.g. utilising the traction motors), magnetic track brakes and eddy current brakes shall be checked according to the tests procedure. SIST EN 15806:2010
EN 15806:2010 (E) 12 5.4.2.3 Energy loss 5.4.2.3.1 General
The energy loss (leakage) from the brake system and all other systems that derive their energy from the same energy source shall be tested. The energy loss shall be monitored during a specified time according as identified in the brake specification.
As applicable, the energy loss tests are performed when brakes are applied and released. As necessary, the energy supply to the subsystem to be tested shall be isolated to facilitate the testing. 5.4.2.3.2 Main reservoirs and all systems supplied by those reservoirs With the various items of pneumatic equipment under pressure (except those intentionally designed to have certain inherent leaks but not in operation), the main reservoir pressure shall be checked in order that the stored energy is kept without feeding within the tolerances defined in the brake specification. 5.4.2.3.3 Auxiliary/brake supply reservoirs/accumulators, brake cylinders and associated devices
With the brake and energy supply system pressurised to the level(s) defined in the brake system specifications and the brake released, apply the emergency brake and then isolate the reservoir(s/accumulators) from the energy supply in such a way that: no further energy can be admitted into the reservoir/accumulators; the means normally used for admitting energy into the reservoir/accumulators are depressurised on the energy supply side; the remaining subsystem under test is the reservoir/accumulator, brake actuation equipment, pressure control devices (e.g. brake distributor) and any non return devices between this subsystem and the energy supply.
The pressure drop in the reservoir or accumulator and the brake actuation equipment shall remain equal or lower than the leakage limits (pressure drop versus time) defined in the brake system specifications. 5.4.2.3.4 Brake pipe
Where applicable the brake pipe leakage shall be tested. All devices supplied by the brake pipe shall be connected. The driver's brake valve shall be isolated. The pressure drop in the brake pipe shall remain equal or lower than the leakage limits (pressure drop versus time) defined in the brake system specifications. 5.4.3 Brake control
5.4.3.1 General The tests are applicable for all types of brake systems (pneumatic, hydraulic, electric). The objective is to establish that the system as a whole and all control components function correctly as described in the brake system specification in association with the energy supply system.
5.4.3.2 Interfaces of the brake system with safety related systems All safety related systems that have an interface with the brake system, not covered by the specific requirements elsewhere in 5.4.3 shall be tested in accordance with the brake system specification. As a minimum, the systems listed below shall be checked in order to ensure that these systems initiate automatic brake application: SIST EN 15806:2010

For all brake application modes, the interaction of signals for brake demand and traction control shall be checked. The input signals and corresponding output signals shall be checked for the following: a) Emergency brake (see 5.4.3.5) The check shall be conducted for each mode of application i.e. by the driver and by all automatic safety systems. b) Service brake (see 5.4.3.7) c) Immobilisation brake (see 5.4.3.22) 5.4.3.4 Check that the brake application command is not adversely affected by the energy supply during braking A full service brake shall be applied; it is necessary to ensure that the
