control of the conformity of production before type approval is granted.

         4.4.  Where a tyre manufacturer submits application for type approval for a range of tyres, it is not considered necessary to carry out a load/speed test on every type of tyre in the range.  Worst case selection may be made at the discretion of the Approval Authority.

         5.  APPROVAL

         5.1.  If the pneumatic tyre submitted for approval in pursuance of this Regulation meets the requirements of paragraph 6 below, approval of that type of tyre shall be granted.

         5.2.  An approval number shall be assigned to each type approved.  Its first two digits (at present 02) shall indicate the series of amendments incorporating the most recent major technical amendments made to the Regulation at the time of issue of the approval.  The same Contracting Party shall not assign the same number to another tyre type covered by this Regulation.

         5.3.  Notice of approval or of extension or refusal or withdrawal of approval or production definitively discontinued of a type of pneumatic tyre pursuant to this Regulation shall be communicated to the Parties to the 1958 Agreement applying this Regulation, by means of a form conforming to the model in Annex 1 to this Regulation.

         5.3.1.  Where type approval is granted for a tyre type suitable for speeds over 300 km/h (see paragraph 4.1.15.), the relevant maximum speed (km/h) and the load carrying capacity (kg) allowed for the maximum speed shall be notified in clear in section 10 of the communication form (see Annex 1 of this Regulation); load carrying capacities for intermediate speeds higher than 300 km/h may also be specified.

         5.4.  There shall be affixed conspicuously to every pneumatic tyre conforming to a type of tyre approved under this Regulation, in the space referred to in paragraph 3.2. above and in addition to the markings prescribed in paragraph 3.1. above, 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; [4]/

         5.4.2.  An approval number.

         5.5.  The approval mark shall be clearly legible and be indelible.

         5.6.  Annex 2 to this Regulation gives an example of the arrangement of the approval mark.

         6.  REQUIREMENTS

         6.1.  Dimensions of tyres

         6.1.1.   Section width of a tyre

         6.1.1.1. The section width shall be calculated by the following formula:

   S = S1 + K(A-A1),

  where:

              S is the "section width" expressed in mm and measured on the measuring rim;

              S1 is the "nominal section width" (in mm) as shown on the  side wall of the tyre in the designation of the tyre as prescribed;

              A is the width (expressed in mm) of the measuring rim, as shown
