taken from the series does not satisfy the requirements of paragraph 8.5.1.1., a further random sample of four vehicles shall be taken from the series and subjected to the tests described in Appendix 1 to Annex 11. The tests may be carried out on vehicles which have been run in for no more than 15,000 km.
              8.5.1.4. The production shall be deemed to conform if at least three vehicles meet the requirements of the tests described in Annex 11, Appendix 1.
              8.6.  Checking the conformity of a vehicle fuelled by LPG or NG/biomethane
              8.6.1.  Tests for conformity of production may be performed with a commercial fuel of which the C3/C4 ratio lies between those of the reference fuels in the case of LPG, or of which the Wobbe index lies between those of the extreme reference fuels in the case of NG/biomethane. In that case a fuel analysis shall be presented to the Approval Authority.
  9.  In-service conformity
              9.1.  Introduction

                This paragraph sets out the in-service conformity requirements for vehicles type approved to this Regulation.

              9.2.  Audit of in-service conformity

              9.2.1.  The audit of in-service conformity by the Approval Authority shall be conducted on the basis of any relevant information that the manufacturer has, under the same procedures as those for the conformity of production defined in Appendix 2 to Agreement E/ECE/324//E/ECE/TRANS/505/Rev.2. Information from Approval Authority and Contracting Party surveillance testing may complement the in-service monitoring reports supplied by the manufacturer.

              9.2.2.  The figures 4/1 and 4/2 of Appendix 4 to this Regulation illustrate the procedure for in-service conformity checking. The process for in-service conformity is described in Appendix 5 to this Regulation.

              9.2.3.  As part of the information provided for the in-service conformity control, at the request of the Approval Authority, the manufacturer shall report to the type Approval Authority on warranty claims, warranty repair works and OBD faults recorded at servicing, according to a format agreed at type approval. The information shall detail the frequency and substance of faults for emissions related components and systems. The reports shall be filed at least once a year for each vehicle model for the duration of the period of up to 5 years of age or 100,000 km, whichever is the sooner.

              9.2.4.  Parameters defining the in-service family

                The in-service family may be defined by basic design parameters which shall be common to vehicles within the family. Accordingly, vehicle types may be considered as belonging to the same in-service family if they have in common, or within the stated tolerances, the following parameters:

              9.2.4.1. Combustion process (two stroke, four stroke, rotary);

              9.2.4.2. Number of cylinders;

              9.2.4.3. Configuration of the cylinder block (in-line, V, radial, horizontally opposed, other). The inclination or orientation
