of the lubricant consumption sequence to the AE calculated in equation 4.

              2.4.5. Development of the complete service accumulation schedule

              2.4.5.1. The service accumulation schedule shall be built up alternating a thermal or a modified thermal sequence, as appropriate, with a lubricant consumption sequence. The aforementioned pattern shall be repeated NTS times, being the NTS value the one calculated either in accordance with section 2.4.2. or with section 2.4.3., as appropriate. An example of a complete service accumulation schedule is given in Appendix 8. A flowchart describing the development of a complete service accumulation schedule is given in Appendix 9.

              2.4.6. Operation of the service accumulation schedule

              2.4.6.1. The engine, fitted with the exhaust after-treatment system incorporating the replacement pollution control device, shall run the service accumulation schedule set out in paragraph 2.4.5.1.

              2.4.6.2. The engine used for the performance of the service accumulation schedule may be different to the engine used in the data collection phase, being the latter always the one for which the replacement pollution control device to be type approved has been designed, and the one to be tested for emissions under paragraph 2.4.3.2.

              2.4.6.3. If the engine used for the performance of the service accumulation schedule features a larger displacement by 20 per cent or more than the engine used in the data collection phase, the exhaust system of the former should be equipped with a by-pass in order to replicate as closely as possible the exhaust flow rate of the latter at the ageing conditions selected.

              2.4.6.4. In the case referred to in paragraph 2.4.6.2., the engine used for the performance of the service accumulation schedule shall be type approved under this Regulation.  In addition, if the device or devices under test are intended for being fitted in an engine system with Exhaust Gas Recirculation (EGR), the engine system used for the service accumulation schedule shall also be fitted with an EGR. If the device or devices under test are intended for not being fitted in an engine system with EGR, the engine system used for the service accumulation schedule shall also not be fitted with an EGR.

              2.4.6.5. The lubricant and the fuel used in the service accumulation schedule shall be as similar as possible to those used during the data collection phase set out in paragraph 2.2. The lubricant must be in line with the recommendation of the engine manufacturer for which the pollution control device is designed. The fuels used should be market fuels fulfilling the corresponding requirements of the European Directive 98/70/EC. On the request of the manufacturer also reference fuels in accordance with this Regulation can be used.

              2.4.6.6. The lubricant shall be changed for maintenance, at the intervals
