        25.1.1 Consider that the modifications made are unlikely to have an appreciable adverse effect, and that in any case the vehicle still complies with the requirements, or
        25.1.2 Require a further test report from the technical service responsible for conducting the test.
        25.2 Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 23.3 above to the Parties to the Agreement which apply this Regulation.
        25.3 The competent authority issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension.

26. CONFORMITY OF PRODUCTION
        26.1 Every vehicle bearing an approval mark as prescribed under this Regulation shall conform, with regard to components affecting the emission of visible pollutants by the engine, to the vehicle type approved.
        26.2 In order to verify conformity as prescribed in paragraph 26.1 above, a vehicle bearing the approval mark required by this Regulation shall be taken from the series.
        26.3 Conformity of the vehicle with the type approved shall be verified on the basis of the description given in the approval form. In addition, verifying tests shall be carried out in the following conditions:
        26.3.1 A vehicle which has not been run in shall be subjected to the test under free acceleration prescribed in annex 5 to this Regulation. The vehicle shall be deemed to conform to the type approved if the absorption coefficient determined does not exceed by more than 0.5 m-1 the figure shown in the approval mark (see paragraph 26.1 above). On the request of the manufacturer, commercially available fuel may be used rather than the reference fuel. In the case of dispute, reference fuel has to be used.
        26.3.2 If the figure determined in the test referred to in paragraph 26.3.1 above exceeds by more than 0.5 m- 1 the figure shown in the approval mark, the engine of the vehicle shall be subjected to the test at steady speeds over the full-load curve, as prescribed in annex 4 to this Regulation. The visible emission levels shall not exceed the limits prescribed in annex 7 to this Regulation.

27. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
        27.1 The approval granted in respect of a vehicle type pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 26.1 above are not complied with or if the vehicle or vehicles taken have failed to pass the tests prescribed in paragraph 26.3 above.
