VEHICLES IN CATEGORIES 1, 2, 3, 4, 5 AND 6 U.K.

1. Braking systems U.K.

The following items are to be included in the roadworthiness test of vehicle braking systems. The test results achieved during the checks on the braking systems must be equivalent as far as is practicable to the technical requirements of Directive 71/320/EEC.

a 48 % for category 1 vehicles not fitted with ABS, or type-approved before 1 October 1991 (date of prohibition of first putting into circulation without EC component type-approval) (Directive 71/320/EEC).
b 45 % for vehicles registered after 1988 or from the date of application of Directive 71/320/EEC, under Member States’ national legislation, whichever is the later.
c 43 % for semi-trailers and draw-bar trailers registered after 1988 or from the date of application of Directive 71/320/EEC, under Member States’ national legislation, whichever is the later.
d 50 % for category 5 vehicles registered after 1988 or from the date of application of Directive 71/320/EEC, under Member States’ national legislation, whichever is the later.
e The reference value for the vehicle axle is the braking effort (expressed in newtons) necessary to achieve this minimum prescribed braking force at the particular weight that the vehicle is presented.
f For category 2 and 5 vehicles the minimum secondary brake performance must be 2,2 m/s2 (as the secondary brake performance was not covered by Directive 71/320/EEC).

1.3. Secondary (emergency) brake performance and efficiency (if met by separate system)
1.3.1. Performance	brake inoperative on one side braking effort from any wheel is less than 70 % of the highest recorded effort from another wheel on the same axle no gradual variation of efficiency (grabbing) automatic brake system not working in the case of trailers
1.3.2. Efficiency	for all vehicle categories, a braking ratio less than 50 %f of the service brake performance defined in 1.2.2 in relation to the maximum authorised mass or, in the case of semi-trailers, to the sum of the authorised axle loads
1.4. Parking brake performance and efficiency
1.4.1. Performance	brake inoperative on one side
1.4.2. Efficiency	for all vehicle categories, a braking ratio less than 16 % in relation to the maximum authorised mass, or, for motor vehicles, less than 12 % in relation to the maximum authorised combination mass of the vehicle, whichever is greater
1.5. Retarder or exhaust brake system performance	no gradual variation of efficiency (retarder) defective
1.6. Anti-lock braking	malfunction of the anti-lock warning device defective
