ANNEX I C U.K. Requirements for construction, testing, installation, and inspection

3. CONSTRUCTION AND FUNCTIONAL REQUIREMENTS FOR RECORDING EQUIPMENT U.K.

3.2 Speed, position and distance measurement U.K.

3.2.2 Measurement of speed U.K.

(33) To ensure a maximum tolerance on speed displayed of ± 6 km/h in use, and taking into account: U.K.

• a ± 2 km/h tolerance for input variations (tyre variations, …),

• a ± 1 km/h tolerance in measurements made during installation or periodic inspections,

the recording equipment shall, for speeds between 20 and 180 km/h, and for characteristic coefficients of the vehicle between 4 000 and 25 000 imp/km, measure the speed with a tolerance of ± 1 km/h (at constant speed).

Note: The resolution of data storage brings an additional tolerance of ± 0,5 km/h to speed stored by the recording equipment. U.K.
