Article 15 Family concept regarding components, separate technical units and systems using certified values

1. Subject to paragraphs 3 to 6, the certified values determined for a parent component, parent separate technical unit or parent system shall be valid, without further testing, for all family members in accordance with the family definition as set out in:

• Appendix 6 to Annex VI as regards the family concept of transmissions, torque converters, other torque transferring component and additional driveline components;

• Appendix 4 to Annex VII as regards the family concept of axles;

• Appendix 5 to Annex VIII as regards the family concept for the purposes of determining air drag.

2. Notwithstanding paragraph 1, for engines, the certified values for all the members of an engine family created in accordance with the family definition as set out in Appendix 3 to Annex V, shall be derived in accordance with paragraph 4, 5 and 6 of Annex V.

For tyres, a family shall consist of one tyre type only.

3. The CO₂ emissions and fuel consumption related properties of the parent component, parent separate technical unit or parent system shall not be better than the properties of any member of the same family.

4. The manufacturer shall provide the approval authority with evidence that the parent component, separate technical units or system fully represents the component family, separate technical unit family or system family.

If, in the framework of testing for the purposes of the second subparagraph of Article 16(3), the approval authority determines that the selected parent component, parent separate technical unit or parent system does not fully represent the component family, separate technical unit family or system family, an alternative reference component, separate technical units or system may be selected by the approval authority, tested and shall become a parent component, parent separate technical unit or parent system.

5. Upon request of the manufacturer, and subject to the agreement by the approval authority, the CO₂ emissions and fuel consumption related properties of a specific component, specific separate technical unit or specific system other than a parent component, parent separate technical unit or parent system, respectively, may be indicated in the certificate on CO₂ emissions and fuel consumption related properties of the component family, separate technical unit family or system family.

The CO₂ emissions and fuel consumption related properties of that specific component, separate technical unit or system shall be determined in accordance with Article 14.

6. Where the characteristics of the specific component, specific separate technical unit or specific system, in terms of CO₂ emissions and fuel consumption related properties as determined in accordance with paragraph 5, lead to higher CO₂ emissions and fuel consumption values than those of the parent component, parent separate technical unit or parent system, respectively, the manufacturer shall exclude it from the existing family, assign it to a new family and define it as the new parent component, parent separate technical unit or parent system for that family or apply for an extension of the certification pursuant to Article 18.

Article 16 Application for a certification of the CO₂ emissions and fuel consumption related properties of components, separate technical units or systems

1. The application for certification of the CO₂ emissions and fuel consumption related properties of the component family, separate technical unit family or system family shall be submitted to the approval authority.

2. The application for certification shall take the form of an information document drawn up in accordance with the model set out in:

The approval authority shall not assign the same number to another component family, separate technical unit family or system family. The certification number shall be used as the identifier of the test report.

4. The approval authority shall create a cryptographic hash of the file with test results, comprising the certification number, by means of the hashing tool referred to in Article 5(5). This hashing shall be done immediately after the test results are produced. The approval authority shall imprint that hash along with the certification number on the certificate on CO₂ emissions and fuel consumption related properties.

Article 18 Extension to include a new component, separate technical unit or system into a component family, separate technical unit family or system family

1. At the request of the manufacturer and upon approval of the approval authority, a new component, separate technical unit or system may be included as a member of a certified component family, separate technical unit family or system family if they meet the criteria for family definition set out in:

• Appendix 3 to Annex V as regards the family concept of engines;

• Appendix 6 to Annex VI as regards the family concept of transmissions, torque converters, other torque transferring component and additional driveline components;

• Appendix 4 to Annex VII as regards the family concept of axles;

• Appendix 5 to Annex VIII as regards the family concept for the purposes of determining air drag.

In such cases, the approval authority shall issue a revised certificate denoted by an extension number.

The manufacturer shall modify the information document referred to in Article 16(2) and provide it to the approval authority.

2. Where the characteristics of the specific component, specific separate technical unit or specific system, in terms of CO₂ emissions and fuel consumption related properties as determined in accordance with paragraph 1, lead to higher CO₂ emissions and fuel consumption values than those of the parent component, parent separate technical unit or parent system, respectively, the new component, separate technical unit or system shall become the new parent component, separate technical unit or system.

Article 19 Subsequent changes relevant for the certification of CO₂ emissions and fuel consumption related properties of components, separate technical units and systems

1. The manufacturer shall notify the approval authority of any changes to the design or the manufacturing process of components, separate technical units or systems concerned which occur after the certification of the values relating to the CO₂ emissions and fuel consumption related properties of the relevant component family, separate technical unit family or system family pursuant to Article 17 and which may have a non-negligible effect on the CO₂ emissions and fuel consumption related properties of those components, separate technical units and systems.

2. Upon receipt of the notification referred to in paragraph 1, the approval authority shall inform the manufacturer whether or not the components, separate technical units or systems affected by the changes continue to be covered by the certificate issued, or whether additional testing in accordance with Article 14 is necessary in order to verify the impact of the changes on the CO₂ emissions and fuel consumption related properties of the components, separate technical units or systems concerned.

3. Where the components, separate technical units or systems affected by the changes are not covered by the certificate, the manufacturer shall, within one month of receipt of that information from the approval authority, apply for a new certification or an extension pursuant to Article 18. If the manufacturer does not apply for a new certification or an extension within that deadline, or if the application is rejected, the certificate shall be withdrawn.
