Regulation (EU) 2018/858 of the European Parliament and of the CouncilShow full title

3. Applicable requirements

3.1. Multi-stage type-approvals shall be granted on the basis of the state of completion of the type of vehicle and shall incorporate all type-approvals granted at earlier stages.

3.2. For the whole-vehicle type-approval, this Regulation (in particular the requirements of Annex I and the particular regulatory acts listed in Annex II) shall apply in the same manner as if the approval would have been granted (or extended) to the manufacturer of the base vehicle.

3.2.1. Where a type of system, component or separate technical unit has not been modified, the system, component or separate technical unit type-approval granted in the previous stage shall remain valid until the expiration date for the first registration, as specified in the particular regulatory act.

3.2.2. Where a type of system has been modified at the subsequent stage of completion of the vehicle, to the extent that the system has to be retested for type-approval purposes, that retesting shall be limited to only those parts of the system that have been modified or affected by the changes.

3.2.3. Where a type of vehicle or a type of system has been modified by another manufacturer at the subsequent stage of completion of the vehicle, to the extent that, apart from the manufacturers name, the vehicle or system may still be considered as the same type, the requirement applying to existing types may still be applied as long as the date for first registration in the relevant regulatory act has not been reached.

3.2.4. The change of category of a vehicle shall lead to the application of the relevant requirements to the new category of vehicle. The EU type-approval certificates from the previous category shall be accepted provided that the vehicle complies with the same requirements as, or more stringent than, those applying to the new category.

3.3. Subject to the agreement of the approval authority, a whole-vehicle type-approval granted to the manufacturer of the subsequent stage of completion of the vehicle does not need to be extended or revised where an extension given at the previous stage vehicle does not affect the subsequent stage or the technical data of the vehicle. However, the type-approval number including the extension of the previous stage(s) vehicle shall be copied in the certificate of conformity of the subsequent stage vehicle.

3.4. Where the cargo area of a complete or completed vehicle of category N or O is modified by another manufacturer for the addition of removable fittings to store and secure the cargo (for example, load space lining, storage racks and roof racks), such items can be treated as part of the pay-mass and a type-approval is not needed, provided both of the following conditions are met:

(a)

the modifications do not affect the vehicle's type-approval in any way, other than an increase of the actual mass of the vehicle;

(b)

the added fittings can be removed without using special tools.
