              The Type Approval Authority shall approve the selected engines and vehicle configurations before the launch of the testing procedures. The selection shall be performed by presenting to the Type Approval Authority the criteria used for the selection of the particular vehicles.
              3.2. The engines and vehicles selected shall be used and registered in the region (e.g. European Union). The vehicle shall have been in service for at least 25,000 km.
              3.3. Each vehicle tested shall have a maintenance record to show that the vehicle has been properly maintained and serviced in accordance with the manufacturer's recommendations.
              3.4. The OBD system shall be checked for proper functioning of the engine. Any malfunction indications and the readiness code in the OBD memory shall be recorded and any required repairs shall be carried out.
              Engines presenting a Class C malfunction shall not be forced to be repaired before testing. The Diagnostic Trouble Code (DTC) shall not be cleared.
              Engines having one of the counters required by provisions of Annex 11 not at "0" may not be tested. This shall be reported to the Type Approval Authority.
              3.5. The engine or vehicle shall exhibit no indications of abuse (such as overloading, misfuelling, or other misuse), or other factors (such as tampering) that could affect emission performance. OBD system fault code and engine running hours information stored in the computer shall be taken into account.
              3.6. All emission control system components on the vehicle shall be in conformity with those stated in the applicable type approval documents.
              3.7. In agreement with the Type Approval Authority, the manufacturer may run in-service conformity testing comprising fewer engines or vehicles than the number given in paragraph 3.1., if the number of engines manufactured within an engine family is less than 500 units per year.
4. Test conditions
              4.1. Vehicle payload

              Normal payload is a payload between 10 and 100 per cent of the maximum payload.

              The maximum payload is the difference between technically permissible maximum laden mass of the vehicle and the mass of the vehicle in running order as specified in Annex 3 to Special Resolution No. 1 (ECE/TRANS/WP.29/1045, as amended by Amendments 1 and 2).

              In case the legally permissible maximum vehicle weight is lower than the technically permissible laden mass of the vehicle, it is permitted to use the legally permissible maximum vehicle weight to determine the vehicle payload for the test run.

              For the purpose of in- service conformity testing the payload may be reproduced and an artificial load may be used.

              Approval authorities may request to test the vehicle with any payload between 10 to 100 per cent of the maximum vehicle payload. In case the mass of the PEMS
