5.   APPROVAL

5.1.

If the representative tyre size of the type of tyre submitted for approval pursuant to this Regulation meets the requirements of paragraphs 6 and 7 below, approval of that type of tyre shall be granted.

5.2.

An approval number shall be assigned to the type of tyre approved. The same Contracting Party may not assign the same number to another type of tyre.

5.3.

Notice of approval or extension of approval or refusal of approval of a type of tyre pursuant to this Regulation shall be communicated to the Parties to the Agreement, which apply this Regulation by means of a form conforming to the model in Annex 1 to the Regulation.

5.3.1.

Tyre manufacturers are entitled to submit an application for extension of type approval to the requirements of other regulations relevant to the tyre type. In that case, a copy of the relevant type approval communication(s), as issued by the relevant Type Approval Authority, shall be attached to the application for extension of approval. All applications for extension of approval(s) shall only be granted by the Type Approval Authority which issued the original approval for the tyre.

5.3.1.1.

When extension of approval is granted to incorporate into the communication form (see Annex 1 to this Regulation) certification(s) of conformity to other regulations, the approval number on the communication form shall be supplemented by suffix(es) to identify the given regulation(s) and the technical prescriptions which have been incorporated by the extension of approval. In relation to each given suffix, the specific type approval number(s) and the Regulation itself shall be added to paragraph 9 of the communication form.

5.3.1.2.

The prefix shall identify the series of amendments of the prescription on tyre performances for the relevant Regulation, e.g. 02S2 to identify the second series of amendments on tyre road rolling sound emissions at stage 2 or 02S1WR1 to identify the second series of amendments on tyre road rolling sound emissions at stage 1, tyre adhesion on wet surfaces and rolling resistance at stage 1 (see paragraph 6.1 for stage 1 and stage 2 definitions). No identification to the series of amendments shall be required if the relevant Regulation is in its original form.

5.3.2.

The following suffixes have been already reserved to identify specific regulations on tyre performance parameters: S to identify additional conformity to the requirements on tyre rolling sound emissions; W to identify additional conformity to the requirements on tyre adhesion on wet surfaces; R to identify additional conformity to the requirements on tyre rolling resistance. Taking into account that two stages are defined for rolling sound and rolling resistance specifications in paragraphs 6.1 and 6.3, S and R will be followed either by the suffix ‘1’ for compliance to stage 1 or by the suffix ‘2’ for compliance to stage 2.

5.4.

In the space referred to in paragraph 4.3 and in accordance with the requirements of paragraph 4.4 there shall be affixed to every tyre size, conforming to the type of tyre approved under this Regulation, an international approval mark consisting of: 5.4.1. A circle surrounding the letter ‘E’ followed by the distinguishing number of the country which has granted approval (12); and 5.4.2. The approval number, which shall be placed close to the circle prescribed in paragraph 5.4.1 either above or below the ‘E’ or to the left or right of that letter. 5.4.3. The suffix(es), and the identification to the relevant series of amendments, if any, as specified in the communication form. One of the suffixes listed below or any combination of them can be used. S1 Sound level at stage 1 S2 Sound level at stage 2 W Wet adhesion level R1 Rolling resistance level at stage 1 R2 Rolling resistance level at stage 2 These suffixes shall be placed to the right or below the approval number, if part of the original approval. If the approval is extended subsequent to Regulation No 30 or 54 approvals, the addition sign ‘+’ and the series of amendment to Regulation No 117 shall be placed in front of the suffix or any combination of suffixes to denote an extension to the approval. If the approval is extended subsequent to the original approval under Regulation No 117, the addition sign ‘+’ shall be placed between the suffix or any combination of suffixes of the original approval and the suffix or any combination of suffixes added to denote an extension to the approval. 5.4.4. The marking on the tyre sidewalls of suffix(es) to the approval number removes the requirement for any additional marking on the tyre of the specific type approval number for conformity to the Regulation(s) to which the suffix refers as per paragraph 5.3.2 above.

5.5.

If the tyre conforms to type approvals under one or more other Regulations annexed to the Agreement in the country which has granted approval under this Regulation, the symbol prescribed in paragraph 5.4.1 need not be repeated. In such a case the additional numbers and symbols of all the Regulations under which approval has been granted in the country which has granted approval under this Regulation shall be placed adjacent to the symbol prescribed in paragraph 5.4.1 above.

5.6.

Annex 2 to this Regulation gives examples of arrangements of approval marks.

(1)  As defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3), document TRANS/WP.29/78/Rev. 2, paragraph 2.

(2)  Class C1 tyres correspond ‘passenger car tyres’ in ISO 4000-1:2010.

(3)  The International System of Units (SI) unit conventionally used for the rolling resistance is the newton-meter per meter, which is equivalent to a drag force in newton.

(4)  The rolling resistance is expressed in newton and the load is expressed in kilo-newton. The rolling resistance coefficient is dimensionless.

(5)  New test tyre definition is needed to reduce potential data variation and dispersion due to tyre aging effects.

(6)  It is permissible to repeat an accepted test procedure.

(7)  An example of machine behaviour is drift.

(8)  The rotating body can be, for example, a tyre assembly or machine drum.

(9)  Measurement reproducibility σm shall be estimated by measuring n times (where n ≥ 3), on a single tyre, the whole procedure described in paragraph 4 of Annex 6 as follows:

Where:

j	=	is the counter from 1 to n for the number of repetitions of each measurement for a given tyre
n	=	number of repetitions of tyre measurements (n ≥ 3)

(10)  Some of these requirements may be specified separately in Regulation No 30 or 54.

(11)  Minimum height of marking: refer to dimension C in Annex 3 of Regulation No 54.

(12)  The distinguishing numbers of the Contracting Parties to the 1958 Agreement are reproduced in Annex 3 to Consolidated Resolution on the Construction of Vehicles (R.E.3), document TRANS/WP.29/78/Rev.2.

(*1)  limit value applies also to tyres marked M+S only.

(*2)  Limit applies also to tyres marked M+S only.

(13)  This test procedure is currently under development.

(14)  See paragraph 3 of Annex 7 to this Regulation.
