Council Directive of 26 July 1971 on the approximation of the laws of the Member States relating to the braking devices of certain categories of motor vehicles and of their trailers (71/320/EEC) (repealed)

[F1 2.1. The manufacturer of the ABS shall supply to the technical service an information document of the system(s) requiring approval. This document shall contain at least the following information: U.K.

2.1.1. General U.K.

2.1.1.1. Name of manufacturer U.K.

2.1.1.2. System name U.K.

2.1.1.3. System variations U.K.

2.1.1.4. System configurations (e. g. 2S/1M, 2S/2M etc.) U.K.

2.1.1.5. Explanation of the basic function and/or philosophy of the system U.K.

2.1.2. Applications U.K.

2.1.2.1. List of trailer types and ABS configurations for which approval is required. U.K.

2.1.2.2. Schematic diagrams of the system configurations installed on the trailers defined in point 2.1.2.1 with consideration given to the following parameters: U.K.

• Sensor locations

• Modulator locations

• Lift axles

• Steering axles

• Tube: type — bore size(s) and lengths

2.1.2.3. Relationship of tyre circumference to the resolution of the exciter, including tolerances. U.K.

2.1.2.4. Tolerance on tyre circumference between one axle and another fitted with the same exciter. U.K.

2.1.2.5. Scope of application with respect to suspension type, e. g. balanced mechanical etc. with reference to the manufacturer and model/type. U.K.

2.1.2.6. Recommendations on differential brake input torque (if any) in relation to the ABS configuration and trailer bogie. U.K.

2.1.2.7. Test data shall be supplied to enable the worst-case axle loading to be determined for the purpose of the energy consumption test. This shall be determined by carrying out a series of tests with incremental axle loads. Operating within the axle load range of ±  10 000  N of the maximum energy consumption value, a minimum of five results within this range is required. Additional results shall be supplied to illustrate the trend outside of the maximum consumption range. Based on the above data the test trailer(s) shall be loaded to represent the determined worst-case. U.K.

2.1.2.8. Additional information (if applicable) to the application of the anti-lock braking system. U.K.

2.1.3. Component description U.K.

2.1.3.1. Sensor(s) U.K.

• Function

• Identification (e.g. part number(s))

2.1.3.2. Controller(s) U.K.

• General description and function

• Identification (e. g. part number(s))

• Failure modes as defined in point 4.1 of Annex X

• Additional features (e. g. retarder control, automatic configuration, variable parameters, diagnostics).

2.1.3.3. Modulator(s) U.K.

• General description and function

• Identification (e. g. part number(s))

• Limitations (e. g. maximum delivery volume to be controlled)

2.1.3.4. Electrical Equipment U.K.

• Circuit diagram(s)

• Powering methods

• Warning lamp sequence

2.1.3.5. Pneumatic Circuits U.K.

• Braking schematics covering the ABS configurations as applied to the trailer types defined in point 2.1.2.1

• Limitations on pipe/tube sizes and associated lengths that have an effect on system performance (e. g. between modulator and brake chamber)

2.1.4. Electro-magnetic compatibility (EMC) U.K.

2.1.4.1. Compliance with point 4.6. of Annex X concerning EMC in terms of susceptibility and emissions will be fulfilled on submission of a technical file or approval to a recognised standard (1) . The file or approval document shall include details of the test method, configurations(s) tested and results obtained.] U.K.
