Category M2 vehicles                                                                                                 160,000 km                           See paragraph 5.4.
                                                                                                                                                          of this Regulation
Category M3 vehicles of classes I, II, A and B with a maximum technically permissible mass not exceeding 7.5 tonnes  188,000 km                           See paragraph 5.4.
                                                                                                                                                          of this Regulation
Category M3 vehicles of classes III and B with a maximum technically permissible mass exceeding 7.5 tonnes           233,000 km                           See paragraph 5.4.
                                                                                                                                                          of this Regulation

              3.2.1.9. Accelerated ageing is permitted by adjusting the service accumulation schedule on a fuel consumption basis. The adjustment shall be based on the ratio between the typical in-use fuel consumption and the fuel consumption on the ageing cycle, but the fuel consumption on the ageing cycle shall not exceed the typical in-use fuel consumption by more than 30 per cent.
              3.2.1.10. The service accumulation schedule shall be fully described in the application for type approval and reported to the Type Approval Authority  before the start of any testing.
              3.2.2. If the Type Approval Authority  decides that additional measurements need to be carried out on the hot WHTC and WHSC tests between the points selected by the manufacturer it shall notify the manufacturer. The revised service accumulation schedule shall be prepared by the manufacturer and agreed by the Type Approval Authority.
              3.3. Engine testing
              3.3.1. Engine system stabilisation
              3.3.1.1. For each engine-after-treatment system family, the manufacturer shall determine the number of hours of vehicle or engine running after which the operation of the engine-after-treatment system has stabilised. If requested by the Type Approval Authority the manufacturer shall make available the data and analysis used to make this determination. As an alternative, the manufacturer may elect to run the engine between 60 and 125 hours or the equivalent mileage on the ageing cycle to stabilise the engine-after-treatment system.
              3.3.1.2. The end of the stabilisation period determined in paragraph 3.3.1.1. will be deemed to be the start of the service accumulation schedule.
              3.3.2. Service accumulation testing
              3.3.2.1. After stabilisation, the engine shall be run over the service accumulation schedule selected by the manufacturer, as described in paragraph 3.2. At the periodic intervals in the service accumulation schedule determined by the manufacturer, and, where appropriate, also stipulated by the Type Approval Authority according to paragraph 3.2.2. the engine shall be tested for gaseous and particulate emissions over the hot WHTC and WHSC tests. In accordance with paragraph 3.2.1.4., if it has been agreed that only one test cycle (hot WHTC or WHSC) be run at each test point, the other test cycle (hot WHTC or WHSC) shall be run at the beginning and end of the service accumulation schedule.
              3.3.2.2. During the service accumulation schedule, maintenance shall be carried out on the engine according to the requirements of paragraph
