The braking force varies proportionally as the action on the control monotonic function ; 2. The warning signal shall be constant not flashing. Any such part as aforesaid whose failure would make it impossible to brake the vehicle with a degree of effectiveness at least equal to that prescribed for secondary braking shall be made of metal or of a material with equivalent characteristics and shall not undergo notable distortion in normal operation of the braking systems.

In addition to the requirements of this annex, Brake Assist Systems shall also be subject to any relevant requirements contained elsewhere within this Regulation. The results of both tests shall be entered in the report. Every test shall be repeated on the unladen vehicle; there may be, in addition to the driver, a second person on the front seat who is responsible for noting the results of the test.

Five sample sets of the brake lining shall be subjected to the comparison test; they shall be compared with five sets of linings conforming to the original components identified in the information document concerning the first approval of the vehicle type concerned.

Application of the parking brake shall also be indicated to the driver. Checking the wear of the service brake friction components 5.

The prescribed braking rate referred to in paragraph 5. The following conditions may also be used: Provisions for the periodic technical inspection of braking systems 5.

Each unit shall be clearly and regultions identifiable e. Alternatively, a sensing device per wheel twin wheels are considered as a single wheelwhich will warn the driver at his driving position when lining replacement is necessary, is acceptable.

The Technical Service responsible for conducting approval tests may at its discretion require comparison of the performance of the brake linings to be carried out in accordance with the relevant provisions contained in Annex 3 to this Regulation. Determine lateral velocity by integrating corrected, filtered and zeroed lateral acceleration data.

The same Contracting Party shall not assign the same number to the same vehicle type equipped with another type of braking equipment, or to another vehicle ede.

The time delay for all filter orders is: In the case where the failure condition causes the electric component to deliver its maximum braking force. Disconnection of the braking surfaces of the parking braking system shall be permitted only on condition that the disconnection is controlled exclusively by the driver from his driving seat, by a system incapable of being brought into action by a leak.


If a Contracting Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation by means of a copy of the communication form conforming to the model in Annex 1 to this Regulation. The first two digits of the approval number indicate that the approval was granted in accordance with the requirements of Regulation No H in its original form.

Tubes may be installed to prevent tyre de-beading. It may be a friction brake when the forces are generated by friction between two parts of the vehicle moving relatively to one another ; an electrical brake when the forces are generated by electro-magnetic action between two parts of the vehicle moving relatively to but not in contact with one another ; a fluid brake when the forces are generated by the action of a fluid situated between two parts of the vehicle moving relatively to one another ; or an engine brake when the forces are derived from an artificial increase in the braking action, transmitted to the wheels, of the engine.

During the tests, the following motion variables, as appropriate, shall be recorded or calculated in accordance with ISO Part 1: This diagram supports the explanation provided under paragraph 3.

If the batteries are new or have been subject to extended storage, they shall be cycled as recommended by the manufacturer. In the case of an optical warning, the yellow warning signal specified in paragraph 5. Vehicles fitted with an electric regenerative braking system of category A. Compensation and functions, such as anti-lock, which may cause deviations from this symmetrical distribution shall be declared. At a level not less than 95 per cent of the full charge level, where the manufacturer has made no specific recommendation; or.

Brake applications shall be made from an initial rotational speed equivalent to that given in row A of the table under paragraph 2. This iterative process continues until both conditions are ultimately satisfied.

Rebulations, in the case of vehicles which are only considered to comply with the requirements of paragraph 5. Furthermore, laden vehicles equipped with anti-lock systems of category 1 shall, under the conditions of paragraph 5.

As from 24 months after the date of entry into force of Supplement 16 to this Regulation Contracting Parties applying this Regulation shall grant Type Approvals only if the vehicle type to be approved meets the requirements of this Regulation as amended by Supplement In the case of a vehicle equipped with an electric regenerative braking system, the requirements depend on the category of this system:. The method by which this may be realised is defined in paragraph 5.

Air cooling, if provided, shall be in accordance with paragraph 3. For regaining speed after braking, the gearbox shall be used in such a way as to attain the speed v 1 in the shortest possible time maximum regulatuons allowed by the engine and gearbox. The vehicle is in a four-wheel drive configuration selected by the driver that is revulations for operation at higher speeds on snow- sand- regulatipns dirt-packed roads and that has the effect of locking the drive gears at the front and rear axles together, provided that in this mode the vehicle meets the stability performance requirements of paragraphs 3.

Plot f 1 and f 2 as a function of z, for both laden and unladen load conditions. The lateral displacement measurement is made at 1,07 seconds after BOS point and is determined by interpolation. Where braking torque for a particular axle or axles is provided by both a friction braking system and an electrical regenerative braking system of category B, disconnection of the latter source is permitted, providing that the ecs braking source remains permanently connected and able to provide the compensation referred to in paragraph 5.

The Type Approval Authority which has granted type approval may at any time verify the conformity control methods applied in each production facility. That Authority may then either: Gegulations driver can at any moment increase or decrease the braking force by acting on the control; 2.

This information shall be subject to discussion and agreement between the Technical Service and the vehicle manufacturer. To replicate a level of state of charge in the batteries for comparative tests, such eegulations those of paragraph 1.

EUR-Lex Access to European Union law

For a vehicle with electrically actuated service brakes powered from traction batteries or an auxiliary battery which receive s energy only from an independent external charging system, these batteries shall, during braking performance testing, be at an average of not more than 5 per cent above that state of charge at which the brake failure warning prescribed in paragraph 5.

These requirements may be checked on high- and low-adhesion road surfaces about 0,8 and 0,3 maximum by modulating the service braking control force. For the purposes of these provisions it is assumed that not more than one failure of the service braking system can occur at one time.
