engine family in accordance with the requirements of paragraph 6.5.1. of this annex shall be made for each group of monitors within the OBD-engine family considered in a vehicle segment.

              A.1.5.2.3. For any segment of vehicles defined in paragraph A.1.4.2.1. of this Appendix, the OBD in-use performance is considered as being demonstrated for the purposes of paragraph 6.5.1. of this annex if, and only if, for any group g of monitors the following conditions are met:

                  (a) The average value of the IUPRg values of the considered sample is greater than 88 per cent of IUPR(min); and

                  (b) More than 34 per cent of all engines in the considered sample have an IUPRg value of more or equal than IUPR(min).

A.1.6. Report to the Type Approval Authority
              The manufacturer shall provide the Type Approval Authority with a report on the in-use performance of the OBD engine family that contains the following information:

              A.1.6.1. The list of the engine families within the considered OBD engine family (Figure 1)

              A.1.6.2. The following information concerning the vehicles considered in the demonstration:

              (a) The total number of vehicles considered in the demonstration;

              (b) The number and the type of vehicle segments;

                  (c) The VIN, and a short description (type-variant-version) of each vehicle.

              A.1.6.3. In-use performance information for each vehicle:

                  (a) The numeratorg, denominatorg, and in-use performance ratio (IUPRg) for each group of monitors;

                  (b) The general denominator, the value of the ignition cycle counter, the total engine running hours.

              A.1.6.4. The results of the in-use performance statistics for each group of monitors:

              (a) The average value of the IUPRg values of the sample;

                  (b) The number and the percentage of engines in the sample that have an IUPRg equal to or above IUPRm(min).

                   Annex 9A ‑ Appendix 2 Model of an OBD in-use performance compliance statement
       "(Name of manufacturer) attests that the engines within this OBD engine family have been so designed and manufactured as to comply with all requirements of paragraphs 6.1. and 6.2. of Annex 9A.

       (Name of manufacturer) makes this statement in good faith, after having performed an appropriate engineering evaluation of the OBD in-use performance of the engines within the OBD engine family over the applicable range of operating and ambient conditions."
