engine manufacturer desires to have the visible pollutants measured over a smaller range of torque and/or speed than is allowed by paragraph 7.3 of Part I of the Regulation, then the approval of the engine type will be for the limited range of torque and/or speed.
        7.5 For such modifications further tests must be carried out to establish free acceleration smoke values in accordance with paragraph 6.3.1 of this Regulation unless these values can be established from tests already carried out as allowed under paragraph 6.3.4.
        7.6 Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5.3 above to the Parties to the Agreement which apply this Regulation.
        7.7 The competent authority issuing the extension of approval shall assign a series number to each communication form drawn up for such an extension.
8. CONFORMITY OF PRODUCTION
        8.1 Every engine identified by an approval mark and/or document as prescribed under paragraph 5.4 of this Regulation shall conform, with regard to components affecting the emission of visible pollutants, to the engine type approved.
        8.2 In order to verify conformity as prescribed in paragraph 8.1 above, an engine shall be taken from the series.
        8.3 Conformity of the engine with the type approved shall be verified on the basis of the description given in the approval form according to annex 2 to this Regulation. In addition, verifying tests shall be carried out in the following conditions:
        8.3.1 An engine which has not been run in shall be subjected to the test under free acceleration prescribed in annex 5 to this Regulation. The engine shall be deemed to conform to the approved type if the absorption coefficient determined does not exceed by more than 0.5m-1 the figure shown in the approval mark or document for that engine (see paragraph 8.1 above). On the request of the manufacturer, commercially available fuel may be used rather than the reference fuel.
        8.3.2 If the figure determined in the test referred to in paragraph 8.3.1 above exceeds by more than 0.5m-l the figure shown in the approval document for that engine, the engine shall be subjected to the test at steady speeds over the full load curve as prescribed in annex 4 to this Regulation. The emission levels shall not exceed the limits prescribed in annex 7 to this Regulation.

9. PENALITIES FOR NON-CONFORMITY OF PRODUCTION
        9.1 The approval granted in respect of an engine type pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 8.1 above are not complied with or if the engine has failed to pass the test prescribed in paragraph 8.3 above.
        9.2 If a Party to the Agreement which applies
