MINIMUM REQUIREMENTS CONCERNING ROADWORTHINESS FACILITIES AND TEST EQUIPMENT I. Facilities and equipment Roadworthiness tests undertaken in accordance with the recommended methods specified in Annex I shall be carried out by using appropriate facilities and equipment. This may include, where applicable, the use of mobile test units. The test equipment that is necessary will depend on the vehicle categories to be tested, as described in Table I. Facilities and equipment shall comply with the following minimum requirements:

(1) A test facility with adequate space for the evaluation of vehicles which meets the necessary health and safety requirements;

(2) A test lane of sufficient size for each test, a pit or lift and, for vehicles having a maximum mass exceeding 3,5 tonnes, a device to lift a vehicle on one of the axles, equipped with appropriate lighting and, where necessary, with aeration devices;

(3) For testing any vehicle, a roller brake tester capable of measuring, displaying and recording the braking forces and the air pressure in air brake systems in accordance with Annex A to standard ISO 21069-1 on the technical requirements of roller brake tester or equivalent standards;

(4) For testing vehicles having a maximum mass not exceeding 3,5 tonnes, a roller brake tester in accordance with item 3, which may not include the recording of braking forces, pedal force and the air pressure in air brake systems and their display; or A plate brake tester equivalent to the roller brake tester in accordance with item 3, which may not include the recording capability of the braking forces, pedal force and the display of air pressure in air brake systems;

(5) A deceleration recording instrument, while non-continuous measurement instruments must record/store measurements at least 10 times per second;

(6) Facilities for the testing of air brake systems, such as manometers, connectors and hoses;

(7) A wheel/axle load measuring device to determine the axle loads (optional facilities for measuring two-wheel loads, such as wheel weight pads and axle weight pads);

(8) A device for testing the wheel-axle suspension (wheel play detector) without lifting the axis, meeting the following requirements:

(a) The device must be equipped with at least two power-operated plates that can be moved in opposite sense in both the longitudinal and the transversal directions;

(b) The movement of the plates must be controllable by the operator from the testing position;

(c) For vehicles having a maximum mass exceeding 3,5 tonnes, the plates shall comply with the following technical requirements:

— Longitudinal and transversal movement of at least 95 mm,

— Longitudinal and transversal movement speed 5 cm/s to 15 cm/s;

(9) A Class II sound level meter, if sound level is measured;

(10) A 4-gas analyser in accordance with Directive 2004/22/EC of the European Parliament and of the Council ();

(11) A device for measuring the absorption coefficient with sufficient accuracy;

(12) One headlamp aiming device allowing the setting of the headlight to be tested in accordance with the provisions for the setting of headlights of motor vehicles (Directive 76/756/EEC); the light/dark boundary must be easily recognisable in daylight (without direct sunlight);

(13) A device for measuring the tread depth of tyres;

(14) A device to connect to the electronic vehicle interface, such as an OBD scan tool;

(15) A device to detect LPG/CNG/LNG leakage, if such vehicles are tested. Any of the above devices may be combined in one composite device, provided that this does not affect the accuracy of each device. II. Calibration of equipment used for measurements Unless specified otherwise by the relevant Union legislation, the interval between two successive calibrations may not exceed:

(i) 24 months for the measurement of weight, pressure and sound level, (ii) 24 months for the measurement of forces, (iii) 12 months for the measurement of gaseous emissions.
