Party that is considered to be particularly representative. In this case, the manufacturer shall demonstrate to the Approval Authority which granted the type approval that the selection is representative (e.g. by the market having the largest annual sales of a vehicle family within the applicable Contracting Party). When an in-service family requires more than one sample lot to be tested as defined in paragraph 9.3.5., the vehicles in the second and third sample lots shall reflect different vehicle operating conditions from those selected for the first sample.

              9.3.3.  The emissions testing may be done at a test facility which is located in a different market or region from where the vehicles have been selected.

              9.3.4.  The in-service conformity tests by the manufacturer shall be continuously carried out reflecting the production cycle of applicable vehicles types within a given in-service vehicle family. The maximum time period between commencing two in-service conformity checks shall not exceed 18 months. In the case of vehicle types covered by an extension to the type approval that did not require an emissions test, this period may be extended up to 24 months.

              9.3.5.  When applying the statistical procedure defined in Appendix 4, the number of sample lots shall depend on the annual sales volume of an in-service family in the territories of a regional organization (e.g. European Community), as defined in the following table:

Registrations per calendar year  Number of sample lots
Up to 100,000                    1

100,001 to 200,000               2

Above 200,000                    3

9.4.  On the basis of the audit referred to in paragraph 9.2., the Approval Authority shall adopt one of the following decisions and actions:
                   (a) Decide that the in-service conformity of a vehicle type or a vehicle in-service family is satisfactory and not take any further action;

                   (b) Decide that the data provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;

                   (c) Decide that based on data from the Approval Authority or Contracting Party surveillance testing programmes, that information provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer;

                   (d) Decide that the in-service conformity of a vehicle type, that is part of an in-service family, is unsatisfactory and proceed to have such vehicle type tested in accordance with Appendix 3.

              9.4.1.  Where Type I tests are considered necessary to check the conformity of emission control devices with the requirements for their performance while in service, such tests shall be carried out using a test procedure meeting the statistical criteria defined in Appendix 2.

              9.4.2.  The Approval Authority, in cooperation with the manufacturer, shall select a sample of vehicles with sufficient mileage
