Family concept for aerodynamic devices using certified values
1. The certified values determined for a parent aerodynamic device shall be valid for all family members of that device in accordance with the family criteria set out in Annex V, Appendix 4.
2. The CO 2 emissions and fuel consumption related properties of the parent aerodynamic device shall not be better than the properties of any member of the same family of aerodynamic devices.
3. Manufacturers of aerodynamic devices shall provide the approval authority with evidence that the parent aerodynamic device fully represents the family of aerodynamic devices.
4. Upon request of a manufacturer of an aerodynamic device, and subject to the agreement of the approval authority, the CO 2 emissions and fuel consumption related properties of the aerodynamic device, other than the parent aerodynamic device, may be indicated in the certificate of the family of aerodynamic devices.
The CO 2 emissions and fuel consumption related properties of the aerodynamic device referred to in the first subparagraph shall be determined in accordance with Annex V, Point 3.
5. Where the CO 2 emissions and fuel consumption related properties of an aerodynamic device, determined in accordance with paragraph 4, lead to a worse performance of the vehicle with regard to its CO 2 emissions and fuel consumption than in the case of the parent aerodynamic device, manufacturers of the aerodynamic devices concerned shall exclude that aerodynamic device from the existing family or apply for an extension of the certification pursuant to Article 18.
Application for a certification of the CO 2 emissions and fuel consumption related properties of aerodynamic devices and their families
1. Manufacturers of aerodynamic devices shall submit to the approval authority the application for the certification of the CO 2 emissions and fuel consumption related properties of those devices or their respective families.
2. The application for certification referred to in paragraph 1 shall take the form of the template set out in Annex V, Appendix 2.
That application shall be accompanied by all of the following:
(a)
an explanation of the elements of design of the aerodynamic device which have a non-negligible effect on the CO 2 emissions, fuel and energy consumption related properties of the aerodynamic device;
(b)
the validation report as specified in Annex V, Point 3;
(c)
the technical report including the computer simulation results as specified in Annex V, Point 3;
(d)
a documentation package for the correct installation of the aerodynamic device;
(e)
a statement of compliance issued pursuant to Annex IV, Point 2 to Regulation (EU) 2018/858.
3. Changes to the aerodynamic device that occur after a certification shall not invalidate the certification, unless its original characteristics or technical parameters are changed in a way that affects the CO 2 emissions and fuel consumption related properties of aerodynamic device concerned.
Certification of CO 2 emissions and fuel consumption related properties of aerodynamic devices
1. If the requirement laid down in in Article 13 is met, approval authorities shall certify the values relating to the CO 2 emissions and fuel consumption related properties of the family of aerodynamic devices and issue a certificate in the form of the template set out in Annex V, Appendix 1.
2. Approval authorities shall assign a certification number in accordance with the numbering system set out in Annex V, Appendix 3.
Approval authorities shall not assign the same certification number to another family of aerodynamic devices. The certification number shall be the identifier of the technical report.
3. Approval authorities shall create a cryptographic hash of the file with the computer simulation results referred to in Article 16(2), point (c), and the certification number, by means of the hashing tool. That hashing shall be done immediately after the computer simulation results are produced. Approval authorities shall imprint the cryptographic hash along with the certification number on the certificate on CO 2 emissions and fuel consumption related properties.
Extension to include an aerodynamic device into a family of aerodynamic devices
1. At the request of a manufacturer of aerodynamic devices, and upon approval of the approval authority concerned, a new aerodynamic device may be included into a family of aerodynamic devices if that device meets the criteria laid down in Annex V, Appendix 4, in which case the approval authority shall issue a revised certificate denoted by an extension number.
Manufacturers of the aerodynamic devices concerned shall modify the information document referred to in Article 16(2) accordingly and provide that document to the approval authority.
2. Where the CO 2 emissions and fuel consumption related properties of the aerodynamic device referred to paragraph 1 are worse than in the case of the parent aerodynamic device, the new aerodynamic device shall become the new parent aerodynamic device.
Changes relevant for the certification of CO 2 emissions and fuel consumption related properties of aerodynamic devices
1. Manufacturers of aerodynamic devices shall notify their approval authority of any changes to the design or manufacturing process of aerodynamic devices that occur after the certification referred to in Article 17 and which may have a non-negligible effect on the performance with regard to CO 2 emissions and fuel consumption of the vehicle equipped with those devices.
2. Upon receipt of the notification referred to in paragraph 1, the approval authority concerned shall inform the manufacturer concerned whether or not the aerodynamic devices affected by the changes continue to be covered by the certificate issued, or whether a computer simulation in accordance with Article 13 is necessary.
3. Where the aerodynamic devices affected by the changes are not covered by the certificate referred to in Article 17(1), the manufacturer concerned shall apply for a new certification or an extension of that certification pursuant to Article 18(1) within one month of receipt of that information from the approval authority.
Where manufacturers of aerodynamic devices do not apply for a new certification or a revision within that deadline, or where the application is rejected, the approval authorities shall withdraw the certificate.
