ANNEX II CONFORMITY OF IN-SERVICE ENGINES OR VEHICLES 1. INTRODUCTION 1.1. This Annex sets out requirements for checking and demonstrating the conformity of in-service engines and vehicles. 2. PROCEDURE FOR IN-SERVICE CONFORMITY 2.1. The conformity of in-service vehicles or engines of an engine family shall be demonstrated by testing vehicles on the road operated over their normal driving patterns, conditions and payloads. The in-service conformity test shall be representative for vehicles operated on their real driving routes, with their normal load and with the usual professional driver of the vehicle. When the vehicle is operated by a driver other than the usual professional driver of the particular vehicle, this alternative driver shall be skilled and trained to operate vehicles of the category subject to be tested. 2.2. If the normal in-service conditions of a particular vehicle are considered to be incompatible with the proper execution of the tests, the manufacturer or the approval authority may request that alternative driving routes and payloads are used. 2.3. The manufacturer shall demonstrate to the approval authority that the chosen vehicle, driving patterns, conditions and payloads are representative for the engine family. The requirements as specified in points 4.1 and 4.5 shall be used to determine whether the driving patterns and payloads are acceptable for in-service conformity testing. 2.4. The manufacturer shall report the schedule and the sampling plan for conformity testing at the time of the initial type-approval of a new engine family. 2.5. Vehicles without a communication interface which permits the collection of the necessary ECU data as specified in points 5.2.1 and 5.2.2 of Annex I, with missing data or with a non-standard data protocol shall be considered as non-compliant. 2.6. Vehicles where the collection of ECU data influences the vehicle emissions or performance shall be considered as non-compliant. 3. ENGINE OR VEHICLE SELECTION 3.1. After the granting of type-approval for an engine family the manufacturer shall perform in-service testing on this engine family within 18 months from first registration of a vehicle fitted with an engine from that family. In case of multistage type-approval first registration means first registration of a completed vehicle. The testing shall be repeated at least every 2 years for each engine family periodically on vehicles over their useful life period as specified in Article 4 of Regulation (EC) No 595/2009. At the request of the manufacturer the testing may stop 5 years after the end of production. 3.1.1. With a minimum sample size of three engines the sampling procedure shall be set so that the probability of a lot passing a test with 20 % of the vehicles or engines defective is 0,90 (producer’s risk = 10 %) while the probability of a lot being accepted with 60 % of the vehicles or engines defective is 0,10 (consumer’s risk = 10 %). 3.1.2. The test statistic quantifying the cumulative number of non-conforming tests at the n-th test shall be determined for the sample. 3.1.3. The pass or fail decision of the lot shall be made according to the following requirements: (a) if the test statistic is less than or equal to the pass decision number for the sample size given in Table 1, a pass decision is reached for the lot; (b) if the test statistic is greater than or equal to the fail decision number for the sample size given in Table 1, a fail decision is reached for the lot; (c) otherwise, an additional engine is tested according to this Annex and the calculation procedure is applied to the sample increased by one more unit. In Table 1 the pass and fail decision numbers are calculated by means of the International Standard ISO 8422/1991.

The selection shall be performed by presenting to the approval authority the criteria used for the selection of the particular vehicles. 3.2. The engines and vehicles selected shall be used and registered in the Union. The vehicle shall have been in service for at least 25 000 km. 3.3. Each vehicle tested shall have a maintenance record to show that the vehicle has been properly maintained and serviced in accordance with the manufacturer’s recommendations. 3.4. The OBD system shall be checked for proper functioning of the engine. Any malfunction indications and the readiness code in the OBD memory shall be recorded and any required repairs shall be carried out. Engines presenting a Class C malfunction shall not be forced to be repaired before testing. The Diagnostic Trouble Code (DTC) shall not be cleared. Engines having one of the counters required by provisions of Annex XIII not at ‘0’ may not be tested. This shall be reported to the approval authority. 3.5. The engine or vehicle shall exhibit no indications of abuse (such as overloading, misfuelling, or other misuse), or other factors (such as tampering) that could affect emission performance. OBD system fault code and engine running hours information stored in the computer shall be taken into account. 3.6. All emission control system components on the vehicle shall be in conformity with those stated in the applicable type-approval documents. 3.7. In agreement with the approval authority, the manufacturer may run in-service conformity testing comprising fewer engines or vehicles than the number given in point 3.1, if the number of engines manufactured within an engine family is less than 500 units per year. 4. TEST CONDITIONS 4.1. Vehicle payload For the purpose of in-service conformity testing the payload may be reproduced and an artificial load may be used. In the absence of statistics to demonstrate that the payload is representative for the vehicle, the vehicle payload shall be 50 to 60 % of the maximum vehicle payload. The maximum payload is the difference between technically permissible maximum laden mass of the vehicle and the mass of the vehicle in running order as specified in accordance to Annex I to Directive 2007/46/EC. 4.2. Ambient conditions The test shall be conducted under ambient conditions meeting the following conditions: Atmospheric pressure greater than or equal to 82,5 kPa, Temperature greater than or equal to 266 K (– 7 °C) and less than or equal to the temperature determined by the following equation at the specified atmospheric pressure: T = – 0,4514 × (101,3 – pb) + 311 where: — T is the ambient air temperature, K — pb is the atmospheric pressure, kPa 4.3.

For the purpose of this Section, ‘approximately’ shall mean the target value ± 5 %. Urban operation is characterised by vehicle speeds between 0 and 50 km/h, Rural operation is characterised by vehicle speeds between 50 and 75 km/h, Motorway operation is characterised by vehicle speeds above 75 km/h. 4.5.1. For M 1 and N 1 vehicles the trip shall consist of approximately 45 % urban, 25 % rural and 30 % motorway operation. 4.5.2. For M 2 and M 3 vehicles the trip shall consist of approximately 45 % urban, 25 % rural and 30 % motorway operation. M 2 and M 3 vehicles of Class I, II or Class A as defined in Annex I to Directive 2001/85/EC of the European Parliament and of the Council ( 1 ) shall be tested in approximately 70 % urban and 30 % rural operation. 4.5.3. For N 2 vehicles the trip shall consist of approximately 45 % urban, 25 % rural and followed by 30 % motorway operation. 4.5.4. For N 3 vehicles the trip shall consist of approximately 20 % urban, 25 % rural and followed by 55 % motorway operation. 4.5.5 The following distribution of the characteristic trip values from the WHDC database may serve as additional guidance for the evaluation of the trip: (a) accelerating: 26,9 % of the time; (b) decelerating: 22,6 % of the time; (c) cruising: 38,1 % of the time; (d) stop (vehicle speed = 0): 12,4 % of the time. 4.6.

The trip shall be selected in such a way that the testing is uninterrupted and the data continuously sampled to reach the minimum test duration defined in point 4.6.5. 4.6.2. Emissions and other data sampling shall start prior to starting the engine. Any cold start emissions may be removed from the emissions evaluation, in accordance with point 2.6 of Appendix 1. 4.6.3. It shall not be permitted to combine data of different trips or to modify or remove data from a trip. 4.6.4. If the engine stalls, it may be restarted, but the sampling shall not be interrupted. 4.6.5. The minimum test duration shall be long enough to complete five times the work performed during the WHTC or produce five times the CO 2 reference mass in kg/cycle from the WHTC as applicable. 4.6.6. The electrical power to the PEMS system shall be supplied by an external power supply unit, and not from a source that draws its energy either directly or indirectly from the engine under test. 4.6.7. The installation of the PEMS equipment shall not influence the vehicle emissions and/or performance. 4.6.8. It is recommended to operate the vehicles under normal daytime traffic conditions. 4.6.9. If the approval authority is not satisfied with the data consistency check results according to Sections 3.2 of Appendix 1 to this Annex, the approval authority may consider the test to be void. 4.6.10. The same route shall be used for the tests of vehicles within the sample described in points 3.1.1 to 3.1.3. 5. ECU DATA STREAM 5.1. Verification of the availability and conformity of the ECU data stream information required for in-service testing. 5.1.1. The availability of the data stream information according to the requirements of point 5.2 of Annex I shall be demonstrated prior to the in-service test. 5.1.1.1. If that information cannot be retrieved by the PEMS system in a proper manner, the availability of the information shall be demonstrated by using an external OBD scan-tool as described in Annex X. 5.1.1.1.1. In the case where this information can be retrieved by the scan-tool in a proper manner, the PEMS system is considered as failing and the test is void. 5.1.1.1.2. In the case where that information cannot be retrieved in a proper manner from two vehicles with engines from the same engine family, while the scan-tool is working properly, the engine is considered as non-compliant. 5.1.2. The conformity of the torque signal calculated by the PEMS equipment from the ECU data stream information required in point 5.2.1 of Annex I shall be verified at full load. 5.1.2.1. The method used to check this conformity is described in Appendix 4. 5.1.2.2. The conformity of the ECU torque signal is considered to be sufficient if the calculated torque remains within the full load torque tolerance specified in point 5. 5.1.2.3. If the calculated torque does not remain within the full load torque tolerance specified in point 5.2.5 of Annex I, the engine is considered to have failed the test. 6. EMISSIONS EVALUATION 6.1. The test shall be conducted and the test results shall be calculated in accordance with the provisions of Appendix 1 to this Annex. 6.2. The conformity factors shall be calculated and presented for both the CO 2 mass based method and the Work based method.
