from the Technical Service responsible for conducting the tests.
7.2. Confirmation or refusal of approval, specifying the alterations, shall be communicated by the procedure specified in paragraph 5.3. to the Contracting Parties to the Agreement which apply this Regulation.
7.3. The Type Approval Authority issuing the extension of approval shall assign a series number to the extension and inform thereof the other Contracting Parties to the 1958 Agreement applying this Regulation by means of a communication form conforming to the model in Annex A2 to this Regulation.
7.4. Extensions for tailpipe emissions (Type 1 test) and OBFCM
              7.4.1. The type-approval shall be extended without the need for further testing to vehicles if they conform to the criteria of paragraph 3.0.1. (a) and (c).

              Additionally to the criteria above, in the cases when the Interpolation Family Vehicle High and/ or Vehicle Low are changed, the new Vehicle High and/or Vehicle Low shall be tested and the CO2 emission values of the tested vehicle resulting from step 9 of Table A7/1 of Annex B7 and step 8 of Table A8/5 in Annex B8 shall be less than or equal to the CO2 emission which lies on a straight line through the CO2 values of the original Vehicles Low and High when plotted against cycle energy and corresponding to the cycle energy demand of the tested vehicle.

              The measured criteria emissions shall respect the limits set out in paragraph 6.3.10.

              The accuracy of the OBFCM shall be calculated for any Type 1 tests performed in order to gain an extension and shall respect the criteria set out in paragraph 4.2 of Appendix 5.

              7.4.1.1.  If the type-approval has been granted only in relation to Vehicle High, it shall only be extended under the circumstances (a), (b) or (c) below:

                  (a) To include additional vehicles which conform to the criteria of paragraph 3.0.1. (a) and (c) and have a cycle energy lower than that of Vehicle High.

                  (b) To create an interpolation family by testing Vehicle Low (preferably using the vehicle which was tested as Vehicle High for the original approval). In this case all vehicles covered by the extended approval shall conform to the criteria of paragraph 3.0.1. (a), (b) and (c).

                  (c) To create an interpolation family by renaming Vehicle High as Vehicle Low and testing Vehicle High (preferably using the vehicle which was tested as Vehicle High for the original approval). In this case all vehicles covered by the extended approval shall conform to the criteria of paragraph 3.0.1. (a), (b) and (c).

7.4.2. Vehicles with periodically regenerating systems
For Ki tests undertaken under Appendix 1 to Annex B6, the type-approval shall be extended to vehicles if they conform to the
