approved under this Regulation, an international approval mark consisting of:

        4.4.1. A circle surrounding the letter "E" followed by the distinguishing number of the country which has granted approval [2]/;

        4.4.2. The number of this Regulation, followed by the letter "R", a dash and the approval number to the right of the circle prescribed in paragraph 4.4.1.

        4.5. If the vehicle conforms to a vehicle type approved 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 4.4.1. need not be repeated; in such a case, the Regulation and approval numbers and the additional symbols of all the Regulations under which approval has been granted in the country which has granted approval under this Regulation shall be placed in vertical columns to the right of the symbol prescribed in paragraph 4.4.1.

        4.6. The approval mark shall be clearly legible and be indelible.
4.7. The approval mark shall be placed close to or on the vehicle data plate.

        5. SPECIFICATIONS AND TESTS

        5.1. General

         The components liable to affect the emissions of CO2 and fuel consumption or the electric energy consumption shall be so designed, constructed and assembled as to enable the vehicle, in normal use, despite the vibrations to which it may be subjected, to comply with the provisions of this Regulation.

        5.2. Description of tests for vehicles powered by an internal combustion engine only

        5.2.1. The emissions of CO2 and fuel consumption shall be measured according to the test procedure described in Annex 6.  Vehicles which do not attain the acceleration and maximum speed values required in the test cycle must be operated with the accelerator control fully depressed until they once again reach the required operating curve.  Deviations from the test cycle must be recorded in the test report.

        5.2.2. For CO2 emissions the results of the test must be expressed in grams per kilometre (g/km) rounded to the nearest whole number.

        5.2.3. Fuel consumption values must be expressed in litres per 100 km (in the case of petrol, LPG, diesel or ethanol) or in m3 per 100 km (in the case of NG), and are calculated according to paragraph 1.4.3. of Annex 6 by the carbon balance method using the measured emissions of CO2 and the other carbon related emissions (CO and HC).  The results will be rounded to the first decimal place.

       5.2.4. For the purpose of the calculation mentioned in paragraph 5.2.3., the fuel consumption shall be expressed in appropriate units and the following fuel characteristics shall be used:
           (a) Density: measured on the test fuel
