ANNEX X CERTIFICATION PROCEDURE FOR PNEUMATIC TYRES

1. Introduction

This Annex describes the certification provisions for tyre with regard to its rolling resistance coefficient. For the calculation of the vehicle rolling resistance to be used as the simulation tool input, the applicable tyre rolling resistance coefficient C_r for each tyre supplied to the original equipment manufacturers and the related tyre test load F_ZTYRE shall be declared by the applicant for pneumatic tyre approval.

2. Definitions

For the purposes of this Annex, in addition to the definitions contained in UN/ECE Regulation No. 54 and in UN/ECE Regulation No.117, the following definitions shall apply:

(1)

‘Rolling resistance coefficient C_r’ means a ratio of the rolling resistance to the load on the tyre

(2)

‘The load on the tyre F_ZTYRE’ means a load applied to the tyre during the rolling resistance test.

(3)

‘Type of tyre’ means a range of tyres which do not differ in such characteristics as:

(a)

Manufacturer's name;

(b)

Brand name or trade mark

(c)

Tyre class (in accordance with Regulation (EC) No 661/2009)

(d)

Tyre-size designation;

(e)

Tyre structure (diagonal (bias-ply), radial);

(f)

Category of use (normal tyre, snow tyre, special use tyre) as defined in UN/ECE Regulation No.117;

(g)

Speed category (categories);

(h)

Load-capacity index (indices);

(i)

Trade description/commercial name;

(j)

Declared tyre rolling resistance coefficient

3. General requirements

3.1. The tyre manufacturer plant shall be certified to ISO/TS 16949.

3.2. Tyre rolling resistance coefficient

The tyre rolling resistance coefficient shall be the value measured and aligned in accordance with Regulation (EC) No 1222/2009, Annex I part A, expressed in N/kN and rounded to the first decimal place, according to ISO 80000-1 Appendix B, section B.3, rule B (example 1).

3.3. Measurement provisions

The tyre manufacturer shall test either in a laboratory of Technical Services as defined in Article 41 of Directive 2007/46/EC which carry out in its own facility the test referred to in paragraph 3.2, or in its own facilities in the case:

(i)

of the presence and responsibility of a representative of a Technical Service designated by an approval authority, or

(ii)

the tyre manufacturer is designated as a technical service of Category A in accordance with Directive 2007/46/EC Art.41.

3.4. Marking and traceability

3.4.1. The tyre shall be clearly identifiable in respect to the certificate covering it for the corresponding rolling resistance coefficient by means of regular tyre markings affixed to the side wall of the tyre as described in Appendix 1 to this Annex.

3.4.2. In the case a unique identification of the rolling resistance coefficient is not possible with the markings referred to in point 3.4.1, the tyre manufacturer shall affix an additional identifier to the tyre. The additional identification shall ensure a unique link of the tyre and its rolling resistance coefficient. It may take a form of:

• quick response (QR) code,

• barcode,

• radio-frequency identification (RFID),

• an additional marking, or

• other tool fulfilling the requirements of 3.4.1.

3.4.3. If an additional identifier is used it shall remain readable until the moment of sales of the vehicle.

3.4.4. In line with Article 19(2) of Directive 2007/46/EC, no type-approval mark is required for tyre certified in accordance with this Regulation.

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.
