IN-SERVICE CONFORMITY CHECK

        1.  INTRODUCTION

        This Appendix sets out the criteria referred to in paragraph 8.2.7. of this Regulation regarding the selection of vehicles for testing and the procedures for the in-service conformity control.

        2.  SELECTION CRITERIA

        The criteria for acceptance of a selected vehicle are defined in paragraphs 2.1. to 2.8. of this Appendix.  Information is collected by vehicle examination and an interview with the owner/driver.

        2.1. The vehicle shall belong to a vehicle type that is type approved under this Regulation and covered by a certificate of conformity in accordance with the 1958 Agreement. It shall be registered and used in a country of the Contracting Parties.

        2.2. The vehicle shall have been in service for at least 15,000 km or 6 months, whichever is the later, and for no more than 80,000 km or 5 years, whichever is the sooner.

        2.3. There shall be a maintenance record to show that the vehicle has been properly maintained, e.g. has been serviced in accordance with the manufacturer's recommendations.

        2.4. The vehicle shall exhibit no indications of abuse (e.g. racing, overloading, misfuelling, or other misuse), or other factors (e.g. tampering) that could affect emission performance. In the case of vehicles fitted with an OBD system, the fault code and mileage information stored in the computer is taken into account. A vehicle shall not be selected for testing if the information stored in the computer shows that the vehicle has operated after a fault code was stored and a relatively prompt repair was not carried out.

        2.5. There shall have been no unauthorised major repair to the engine or major repair of the vehicle.

        2.6. The lead content and sulphur content of a fuel sample from the vehicle tank shall meet applicable standards and there shall be no evidence of misfuelling. Checks may be done in the exhaust, etc.

        2.7. There shall be no indication of any problem that might jeopardise the safety of laboratory personnel.

        2.8. All anti-pollution system components on the vehicle shall be in conformity with the applicable type approval.

        3. DIAGNOSIS AND MAINTENANCE

        Diagnosis and any normal maintenance necessary shall be performed on vehicles accepted for testing, prior to measuring exhaust emissions, in accordance with the procedure laid down in paragraphs 3.1. to 3.7. below.

        3.1. The following checks shall be carried out: checks on air filter, all drive belts, all fluid levels, radiator cap, all vacuum hoses and electrical wiring related to the anti-pollution system for integrity; checks on ignition, fuel metering and anti-pollution device components for maladjustments
