are not met following the subsequent tests pursuant to this point, additional tests may be performed for the purpose of determining the accuracy, however, the total number of tests shall not exceed three tests for a vehicle tested without using the interpolation method (vehicle H), and six tests for a vehicle tested using the interpolation method (three tests for vehicle H and three tests for vehicle L). The accuracy shall be recalculated for the additional subsequent Type 1 tests in accordance with the formulae in paragraph 4.2., using the fuel consumed determined and accumulated over all performed tests. The requirement shall be deemed to be fulfilled once the accuracy is higher than - 0.05 and lower than 0.05. Where the tests have been performed only for the purpose of determining the accuracy of the OBFCM device, the results of the additional tests shall not be taken into account for any other purposes.

              5. Access to the information provided by the OBFCM device

              5.1. The OBFCM device shall provide for standardised and unrestricted access of the information specified in paragraph 3. and shall conform to the standards referred to in paragraphs 6.5.3.1. (a) and 6.5.3.2. (a) of Appendix 1 to Annex C5.

              5.2. By way of exemption from the reset conditions specified in the standards referred to in paragraph 5.1. and notwithstanding paragraphs 5.3. and 5.4., once the vehicle has entered into service the values of the lifetime counters shall be preserved.

              5.3. The values of the lifetime counters may be reset only for those vehicles for which the memory type of the engine control unit is unable to preserve data when not powered by electricity. For those vehicles the values may be reset simultaneously only in the case the battery is disconnected from the vehicle. The obligation to preserve the values of the lifetime counters shall in this case apply for new type approvals at the latest from 1 January 2022 and for new vehicles from 1 January 2023.

              5.4. In the case of malfunctioning affecting the values of the lifetime counters, or replacement of the engine control unit, the counters may be reset simultaneously to ensure that the values remain fully synchronised.

Appendix 6

Requirements for vehicles that use a reagent for the exhaust after-treatment system
              1.  This appendix sets out the requirements for vehicles that rely on the use of a reagent for the after-treatment system in order to reduce emissions. Every reference in this appendix to 'reagent tank' shall be understood as also applying to other containers in which a reagent is stored.

              1.1. The capacity of the reagent tank shall be such that a full reagent tank does not need to be replenished over an average
