ANNEX IVSupplementary provisions
ANNEX IV PERIODIC INSPECTIONS 1. On-board weighing equipment (‘OBW’) shall undergo periodic inspections by weighing the vehicle or vehicle combination on certified weighing devices in accordance with Article 5(2)(b) of this Regulation, such as portable weigh pads or a weighbridge. 2. The following vehicles shall be subject to inspection: a) motor vehicles; b) trailers and semi-trailers featuring a trailer unit (‘TU’). 3. Trailers and semi-trailers subject to inspection according to point 2 shall undergo the inspection attached to a motor vehicle. Motor vehicles intended to tow semi-trailers shall undergo the inspection attached to a semi-trailer. 4. The periodic inspection shall consist of: a) a three-load test, which shall be carried out two years after the registration of the vehicle and every four years thereafter; b) a single-load test, which shall be carried out two years after the first three-load test and every four years thereafter.

Three-load test A three-load test shall be performed by loading the vehicle with three different loads, which values shall be calculated as follows: a) a load between 45 % and 55 % of the technically permissible maximum laden mass of the vehicle; b) a load between 65 % and 75 % of the technically permissible maximum laden mass of the vehicle; c) A load between 90 % and 100 % of the technically permissible maximum laden mass of the vehicle. 6. The single load test shall be performed by loading the vehicle with a load which is at least 90 % of the technically permissible maximum laden mass of the vehicle. 7. For trailers and semi-trailers featuring a TU and for motor vehicles intended to tow a semi-trailer, the loads in points 5 and 6 shall be calculated in respect of the technically permissible maximum laden mass of the vehicle combination. 8. Specific provisions for dynamic OBWs 8.1. If the technically permissible maximum laden mass of the vehicle or vehicle combination exceeds the maximum authorised weight, the loads in points 5 and 6 shall be calculated in respect of the maximum authorised weight. 8.2. In order to get a load value from the OBW, the vehicle or vehicle combination shall be driven over a certain distance under specific conditions to be specified in the manufacturer's guidelines. 9. The inspection shall be deemed to have failed when a) the load value displayed by the OBW corresponding to the load between 90 % to 100 % of the technically permissible maximum laden mass referred to in point 5(c) does not conform to the values measured by the certified weighing device, with the level of accuracy set out in point 8 of Annex I, and b) the load values displayed by the OBW corresponding to the loads between 45 % and 55 %, and between 65 % and 75 % of the technically permissible maximum laden mass as referred to in points 5(a) and 5(b), do not conform to the values measured by the certified weighing device with a level or accuracy of ± 15 %. 10. When the inspection fails the OBW shall undergo a new inspection no later than two months after the previous one. 11. Flexibilities for periodic inspections: In order to facilitate the performance of periodic inspections for specific types of vehicles, and in order to reduce the impact of periodic inspections on the regular activities of drivers and hauliers, Member States may consider the application of the following flexibilities for vehicles registered in their territory: a) the three load values referred to in point 5 may be obtained over a period of three months; b) the actual weighing of the vehicle may be carried out on certified weighing devices not belonging to the facilities of the OBW-workshops referred to in Article 5 of this Regulation, provided that the weighing operation is being supervised by a member of the staff of an OBW-workshop. The owner of the vehicle shall provide evidence to the OBW-workshop that the weighing has been performed on a certified weighing device; c) for vehicles or vehicle combinations which specific configuration makes technically impossible to exceed the maximum authorised weight during normal use (e.g. road tankers) the loads referred to in points 5 and 6 may have other values; in the case of the three-load test, the difference between two consecutive loads shall be at least 15 % of the maximum authorised weight.
