Annex 1 —

Annex 2 —

Annex 3 —

(a)

Vehicles with a Vmax of < 25 km/h;

(b)

Vehicles equipped for disabled riders.

2.1.

‘Antilock brake system (ABS)’ means a system which senses wheel slip and automatically modulates the pressure producing the braking forces at the wheel(s) to limit the degree of wheel slip.

2.2.

‘Approval of a vehicle’ means the approval of a vehicle type with regard to braking.

2.3.

‘Baseline test’ means a stop or a series of stops carried out in order to confirm the performance of the brake prior to subjecting it to a further test such as the heating procedure or wet brake stop.

2.4.

‘Brake’ means those parts of the brake system where the forces opposing the movement of the vehicle are developed.

2.5.

‘Brake system’ means the combination of parts consisting of the control, transmission, and brake, but excluding the engine, whose function it is to progressively reduce the speed of a moving vehicle, bring it to a halt, and keep it stationary when halted.

2.6.

‘Combined brake system (CBS)’ means:

For vehicle categories L1 and L3 : a service brake system where at least two brakes on different wheels are operated by the actuation of a single control.

For vehicle categories L2 and L5 : a service brake system where the brakes on all wheels are operated by the actuation of a single control.

For vehicle category L4 : a service brake system where the brakes on at least the front and rear wheels are operated by the actuation of a single control. (If the rear wheel and sidecar wheel are braked by the same brake system, this is regarded as the rear brake.)

2.7.

‘Components of the braking system’ means one of the individual parts which, when assembled, constitute the braking system.

2.8.

‘Control’ means the part actuated directly by the rider in order to supply or control the energy required for braking the vehicle to the transmission.

2.9.

‘Different types of braking systems’ means devices which differ in such essential respects as:

2.10.

‘Driver mass’ means the nominal mass of a driver that shall be 75 kg (subdivided into 68 kg occupant mass at the seat and 7 kg luggage mass).

2.11.

‘Engine disconnected’ means when the engine is no longer connected to the driving wheel(s).

2.12.

‘Gross vehicle mass’ or ‘maximum mass’ means the technically permissible maximum laden mass as declared by the manufacturer.

2.13.

‘Initial brake temperature’ means the temperature of the hottest brake before any brake application.

2.14.

‘Laden’ means so loaded as to attain the gross vehicle mass as defined in paragraph 2.12.

2.15.

‘Lightly loaded’ means mass in running order plus 15 kg for test equipment, or the laden condition, whichever is less. In the case of ABS tests on a low friction surface (Annex 3, paragraphs 9.4 to 9.7), the mass for test equipment is increased to 30 kg to account for outriggers.

2.16.

‘Mass in running order’ means the sum of the unladen vehicle mass and driver mass.

2.17.

‘Peak braking coefficient (PBC)’ means the measure of tyre to road surface friction based on the maximum deceleration of a rolling tyre.

2.18.

‘Power-assisted braking system’ means a brake system in which the energy necessary to produce the braking force is supplied by the physical effort of the rider assisted by one or more energy supplying devices, for example vacuum assisted (with vacuum booster).

2.19.

‘Secondary brake system’ means the second service brake system on a vehicle equipped with a combined brake system.

2.20.

‘Service brake system’ means a brake system which is used for slowing the vehicle when in motion.

2.21.

‘Single brake system’ means a brake system which acts on only one axle.

2.22.

‘Split service brake system (SSBS)’ means a brake system that operates the brakes on all wheels, consisting of two or more subsystems actuated by a single control designed so that a single failure in any subsystem (such as a leakage type failure of a hydraulic subsystem) does not impair the operation of any other subsystem.

2.23.

‘Stopping distance’ means the distance travelled by the vehicle from the point the rider begins to actuate the brake control to the point at which the vehicle reaches a full stop. For tests where the simultaneous actuation of two controls is specified, the distance travelled is taken from the point the first control is actuated.

2.24.

‘Test speed’ means the vehicle speed measured the moment the driver begins to actuate the brake control(s). For tests where the simultaneous actuation of two controls is specified, the vehicle speed is taken from the point the first control is actuated.

2.25.

‘Transmission’ means the combination of components that provide the functional link between the control and the brake.

2.26.

‘Unladen vehicle mass’ means the nominal mass of the vehicle as indicated by the manufacturer(s) including all factory fitted equipment for normal operation of that vehicle (e.g. fire extinguisher, tools, spare wheel), plus coolant, oils, 90 per cent of fuel and 100 per cent of other gas or liquids, as specified by the manufacturer.

2.27.

‘Vehicle type’ means a sub-category of L-category vehicles which do not differ in such essential respects as:

2.28.

‘Vmax’ means either the speed attainable by accelerating at a maximum rate from a standing start for a distance of 1,6 km on a level surface, with the vehicle lightly loaded, or the speed measured in accordance with ISO 7117:1995.

2.29.

‘Wheel lock’ means the condition that occurs when there is a slip ratio of 1,00.

3.2.1.

A description of the vehicle type with regard to the items specified in paragraph 2.27. The numbers and/or symbols identifying the vehicle type and the engine type shall be specified;

3.2.2.

A list of components, duly identified, constituting the braking device;

3.2.3.

A diagram of the assembled braking system and an indication of the position of its components on the vehicle;

3.2.4.

Detailed drawings of each component to enable it to be easily located and identified.

4.4.1.

A circle surrounding the letter ‘E’ followed by the distinguishing number of the country which has granted approval (2);

4.4.2.

The number of this Regulation, followed by the letter ‘R’, a dash and the approval number to the right of the circle prescribed in paragraph 4.4.1.

(a)

Have a control which is separate from the service brake system controls; and

(b)

Be held in the locked position by solely mechanical means.

(a)

Two separate service brake systems, except CBS, which, when applied together, operate the brakes on all wheels; or

(b)

A split service brake system; or

(c)

A CBS that operates the brakes on all wheels and a secondary brake system which may be the parking brake system.

5.1.8.1.

A parking brake system; and

5.1.8.2.

A foot-actuated service brake system which operates on the brakes on all wheels, by way of either:

(a)

Have a sealed, covered, separate reservoir for each brake system;

(b)

Have a minimum reservoir capacity equivalent to 1,5 times the total fluid displacement required to satisfy the new to fully worn lining condition with the worst case brake adjustment condition; and

(c)
