[F1 ANNEX VIII U.K. Conditions governing the testing of vehicles with inertia (overrun) braking systems

Textual Amendments

F1 Substituted by Commission Directive 98/12/EC of 27 January 1998 adapting to technical progress Council Directive 71/320/EEC on the approximation of the laws of the Member States relating to the braking devices of certain categories of motor vehicles and their trailers (Text with EEA relevance).

1. GENERAL PROVISIONS U.K.

1.1. The ‘ inertia (overrun) braking system ’ of a trailer comprises the control device, the transmission and the brake, as defined in point 1.4. U.K.

1.2. The ‘ control device ’ is the combination of components comprising the coupling head. U.K.

1.3. The ‘ transmission ’ is the combination of components comprised between the coupling head and the first part of the brake. U.K.

1.4. The ‘ brake ’ is the part in which the forces opposing the movement of the vehicle develop. The first part of the brake is either the lever actuating the brake cam or similar parts (mechanical-transmission inertia brake) or the brake cylinder (hydraulic-transmission inertia brake). U.K.

1.5. Braking systems in which accumulated energy (for instance, electric, pneumatic or hydraulic) is transmitted to the trailer by the towing vehicle and is only controlled by the force at the coupling shall not be deemed to be inertia braking systems within the meaning of this Directive. U.K.

1.6. Tests U.K.

1.6.1. Determination of the main characteristics of the brake. U.K.

1.6.2. Determination of the main characteristics of the control device and testing as to whether that device conforms with the provisions of this Directive. U.K.

1.6.3. Testing on the vehicle: U.K.

• the compatibility of the control device and the brake

• the transmission.]
