To receive an EU type-approval* with regard to emissions, vehicle repair and maintenance information the manufacturer must show that the vehicle complies with the requirements set out in this regulation when tested under the specified procedures.
All vehicles must respect the tailpipe (exhaust pipe) emission limits set out in Regulation (EC) No 715/2007 when tested in RDE and WLTP tests, and also a series of other tests that include checking for evaporative emissions (i.e. emissions originating from the fuel tank), or checking at low ambient temperatures.
On-board diagnostics (OBD) systems must be installed on all vehicles to identify all forms of deterioration or malfunction over the lifetime of the vehicle — the regulation sets out requirements for the OBD system during normal use.
Manufacturers must install devices to continuously measure the quantity of fuel/energy used to operate the vehicle.
Applying for EU type-approval
Manufacturer must submit an application to the approval authority for EU type-approval of a vehicle with regard to emissions and access to vehicle repair and maintenance information which includes:
the results of the regulated tests;
detailed written information fully describing the functional operation characteristics of the OBD system;
a description of the provisions taken to prevent tampering with and modification of the emission control computer, odometer including the recording of mileage values;
an extended documentation package which allows an authority to assess whether the ban on ‘defeat devices’* which reduce the level of emission control is respected.
If the relevant requirements are met, the approval authority grants an EU type-approval and issue a type-approval number.
Conformity of production
Checks must be made by the manufacturer to ensure that all vehicles produced by the manufacturer respect the emission limits.
Checks must be performed to ensure the properly maintained and used vehicles respect the limits during their lifetime set as:.
between 15,000 km or 6 months, whichever occurs later; and
100,000 km or 5 years, whichever occurs sooner.
Pollution control devices
Pollution control devices such as catalytic converters must be type-approved as separate technical units.
The regulation sets out the rules and procedures for applying for type-approval for such devices.
Access to vehicle OBD and vehicle repair and maintenance information
Manufacturers must put in place arrangements and procedures to ensure that vehicle OBD, and repair and maintenance information is readily accessible.
Type-approval will be only be granted by the authorities after receiving from the manufacturer a Certificate on Access to Vehicle OBD and Vehicle Repair and Maintenance Information.
Approval authorities can check compliance either on the basis of a complaint or assessment by a technical service.
Where a manufacturer has been found to have not complied, measures including suspension of the type-approval may be taken.
Type-approval: the procedure by which a product is certified to meet a minimum set of regulatory and technical requirements.
Defeat devices: deliberate changes to the emission control system, designed to artificially reduce its effectiveness under normal vehicle use.
