Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance) (c. 2400)

ANNEX X CERTIFICATION PROCEDURE FOR PNEUMATIC TYRES

4. Conformity of the certified CO₂ emissions and fuel consumption related properties

4.1. Any tyre certified under this Regulation shall be in conformity to the declared rolling resistance value as per paragraph 3.2 of this Annex.

4.2. In order to verify conformity of the certified CO₂ emissions and fuel consumption related properties, production samples shall be taken randomly from series production and tested in accordance with the provisions set out in paragraph 3.2.

4.3. Frequency of the tests

4.3.1 The tyre rolling resistance of at least one tyre of a specific type intended for the sales to the original equipment manufacturers shall be tested every 20 000 units of this type per year (e.g. 2 conformity verifications per year of the type whose annual sales volume to the original equipment manufacturers is between 20 001 and 40 000 units).

4.3.2 In case the deliveries of a specific tyre type intended for the sales to the original equipment manufacturers is between 500 and 20 000 units per year, at least one conformity verification of the type shall be carried out per year.

4.3.3 In case the deliveries of a specific tyre type intended for the sales to the original equipment manufacturers is below 500 units, at least one conformity verification as described in paragraph 4.4 shall be applied every second year.

4.3.4 If the volume of tyres delivered to the original equipment manufacturers indicated in 4.3.1 is met within 31 calendar days the maximum number of conformity verifications as described in paragraph 4.3 is limited to one per 31 calendar days.

4.3.5 The manufacturer shall justify (ex. by showing sales numbers) to the approval authority the number of tests which has been performed

4.4 Verification procedure

4.4.1 A single tyre shall be tested in accordance with paragraph 3.2. By default, the machine alignment equation shall be the one valid at the date of verification testing. Tyre manufacturer may request the application of the alignment equation that was used during the certification testing and reported in the information document.

4.4.2 In the case the value measured is lower or equal to the declared value plus 0,3 N/kN, the tyre is considered compliant.

4.4.3. In the case, the value measured exceeds the declared value by more than 0,3 N/kN, three additional tyres shall be tested. If the value of the rolling resistance of at least one of the three tyres exceeds the declared value by more than 0,4 N/kN, provisions of Article 23 shall apply.
