Limit values The retrofitted engine system shall not exceed the emission limits for the relevant pollutants (NO or PM or x both as appropriate for the REC Class) of a more stringent emission stage as specified in Regulation No 49 or in Regulation No 96 as appropriate and measured using the test procedure(s) associated with the limit values to be achieved. The retrofitted engine system shall meet at least the emission limits for the stage to which the base engine was approved for each of the other controlled pollutants relevant to that stage. 8.2.1. The requirements for each class of REC in terms of meeting the limits of the next more stringent emission stage are illustrated in the tables in Annex 9 to this Regulation. 8.2.2. In the case of an engine not type-approved in accordance with the requirements of either Regulation No 49 or Regulation No 96, the emissions of each of the regulated pollutants (CO, HC, NO, and PM) in x the initial condition shall not exceed the limit values for the emissions stage immediately below that for which certification of the REC is sought. 8.3. Reduction levels and reduction efficiency 8.3.1. The reduction level of a REC system is characterised by means of its reduction efficiency as specified in Table 1: Table 1 Reduction levels Minimum reduction efficiency (%) PM mass NO X Reduction level 01 90 60 8.3.2. The reduction efficiency shall be determined by comparison of the emissions measured over the weighted WHTC for REC to be applied to heavy-duty engines or over the weighted NRTC for REC to be applied to non-road mobile machinery or agricultural and forestry tractor engines. The reduction efficiency shall be calculated as defined in 8.3.4 of this Regulation. 8.3.3. For the purpose of this Regulation the reduction efficiency for NO shall be applicable to systems which x are intended to reduce NO, and the PM reduction level to systems intended to reduce PM. For Class IV x REC the reduction levels for both NO and PM shown in Table 1 of this Regulation shall be met. x 8.3.4. The reduction efficiency shall be calculated from the measured emissions of the relevant pollutant downstream of the REC (E ) and the engine system emissions measured before fitment of the REC (E ) REC Base for that pollutant, both measured in accordance with the procedures defined in this Regulation: reduction efficiency (per cent) = (1 – (E /E )) × 100. REC Base 8.4. NO emissions requirements 2 8.4.1. For a Class I REC, there shall be no increase in NO emissions above the NO baseline emissions, measured 2 2 as defined in Annex 5 to this Regulation. 8.4.2. For a Class IIA REC, the NO incremental increase shall not be more than 20 percentage points greater 2 than the level recorded when no REC is fitted (baseline). As an example, if baseline NO is 10 per cent of 2 NO, the maximum permitted NO emission with the REC is 30 per cent of NO measured as defined in x 2 x Annex 5 to this Regulation. For a Class IIB REC, the NO incremental increase shall be no more than 2 30 percentage points.27.4.2018 EN Official Journal of the European Union L 109/109 8.4.3. For Class III REC, there shall be no increase of NO emissions measured in g/kWh and as defined in 2 Annex 6 to this Regulation. 8.4.4. For Class IV REC, there shall be no increase of NO emissions measured in g/kWh and as defined in 2 Annex 7 to this Regulation. 8.5. Particle number emissions requirements 8.5.1. Class I, Class IIA or IIB and Class IV REC approved to PM Reduction Level 01 shall provide a reduction efficiency for particle number of at least 97 per cent from the engine baseline emissions of the test engine as defined in paragraph 12 when measured using the test procedure(s) set out in this Regulation. 8.5.2. Direct sampling from raw exhaust gas prior to dilution is permitted. The dilution ratios of the particle number diluters (PND1 and PND2 of the particle transfer system, as defined in Regulation No 49) shall then be adapted to the measurement range of the particle number counter (PNC). 8.5.3. The particle number reduction efficiency is determined as the difference of 1 minus the penetration, which is the ratio between the particle number emissions downstream of the REC system and the particle number emission of the engine system before fitment of the REC. The particle number reduction efficiency is indicated as a percentage. The particle number reduction efficiency shall be determined for the appropriate test cycle as defined in paragraph 8.3.2. reduction efficiency (percent) = (1 – (E /E )) × 100. REC Base 8.5.4. If two particle number measurement systems are used in parallel for measurement of the particle number reduction efficiency, they shall give measurements within 5 per cent of each other when measuring simul­ taneously from the same sample point. 8.6. Secondary emissions requirements 8.6.1. The manufacturer of the REC system shall provide documentary evidence to show that materials and processes used in the REC do not present any additional hazard to health and the environment. 8.6.2. For Class III and Class IV REC, emissions of ammonia shall not exceed a mean value of 25 ppm when measured using the procedures defined in Appendix 7 to Annex 4 to the 06 series of amendments to Regulation No 49. 8.6.3. The REC shall not increase secondary emissions to concentrations known to be hazardous to health. 8.6.4. The applicant for approval shall provide an assessment of the performance of the REC with respect to secondary emissions. The assessment shall address all likely secondary emissions from the REC having regard to its working principle, its design, its method of construction, and the materials employed. 8.6.4.1. The assessment shall, in particular: (a) In cases where the REC contains copper or copper compounds, address the possible formation of dioxins; (b) In cases where the REC makes use of a fuel-borne catalyst, consider the impact upon the production of secondary emissions of: (i) The absence of that catalyst and (ii) Its presence at up to twice the recommended or intended concentration. 8.6.4.2. The assessment shall name each of the species of secondary emissions considered. 8.6.4.3. The assessment may be based upon sound engineering analysis and judgement, upon the results of tests or simulations, upon the results of analysis or tests of similar systems or technologies, or upon any combination of these elements.L 109/110 EN Official Journal of the European Union 27.4.2018 8.6.4.4. For the purposes of this Regulation secondary emissions produced at concentrations not significantly higher than the concentrations produced by original equipment engine systems shall be considered not to be hazardous to health. 8.6.5. The applicant may be required to perform tests for secondary emissions as a prerequisite for approval in cases where the assessment of the performance of the REC with respect to secondary emissions produces a reasonable expectation that the requirements of paragraph 8.6.3 above will not be met. 9. DURABILITY REQUIREMENTS 9.1.

The engine for the durability run may be different from the test engine used for tests to establish the reduction level of the REC, but shall be an engine within the declared application range of the particular REC. 9.3. The content of the test is as follows: (a) 1 000 hours service accumulation of the REC with recording of all relevant operating data of the engine concerned including type and consumption of fuel and lubricating oil, and when appropriate reagent or additive required by the REC device, and continuous second-by-second data logging of exhaust temperature before the REC and pressure loss over the REC. In the case of a field test the REC shall be sealed by the Technical Service and the data-logging shall be carried out by the REC manufacturer or by the operator of the vehicle or machine on which the endurance test is performed; (b) In the case of REC that operate with additives or makes use of a reagent, verification of the correct dosing rate shall additionally be performed at the beginning of the field test, after 500 hours of operation and after 1 000 hours of operation. 9.4. After completion of the durability run the REC system used to demonstrate durability shall be used for any further evaluation testing with the original test engine. In the event that the original test engine is no longer functional, an engine of the same type may be used with the prior agreement of the Type Approval Authority. 9.5. The REC system shall meet the requirements of paragraph 8 when tested in accordance with paragraph 9.4 after completion of the service accumulation. 10. APPLICATION RANGE 10.1.

The application range shall not be extended to engines with a baseline emission stage less stringent than the baseline emission stage of the test engine. 10.5. If the applicant can prove that a REC tested for vehicles of Category M , M and N and their CI engines, is 2 3 also designed for use in the same structural manner on CI engines for use in non-road mobile machinery or Category T vehicles and the test engine in accordance with paragraph 12 below is representative for such applications and also meets the family criteria of paragraphs 14, 15 or 16 below as appropriate, the application range can be extended to CI engines for use in non-road mobile machinery and category T vehicles. Extending the range of a REC that has been approved for use with CI engines in non-road mobile machinery or category T vehicles to cover on-road applications in the way described in this paragraph is not permitted. 11. MODIFICATIONS TO ENGINE BASELINE EMISSIONS 11.1. Any modifications of engine operation parameters which might affect the engine baseline emissions must be kept within the limits specified by the original engine manufacturer (for example maximum allowable exhaust gas back pressure or limits set for impact of external devices upon the electrical or data handling systems). 11.2. In cases where additional measures with respect to emission-relevant components or system components, such as modifications to the exhaust gas recirculation (EGR) control, are necessary in order to ensure proper functioning of the engine and exhaust after treatment systems in conjunction with the REC, the applicant shall provide a detailed description of the design modification along with an explanation of how the modification will change the operation and performance of the emission control strategy. To support its claims, the applicant shall submit additional test data, engineering justification and analysis, or any other information deemed necessary by the Type Approval Authority or Technical Service to address the differences between the modified and original designs. 11.3. The emission control system of the original engine manufacturer shall not be modified, except for: (a) Modifications allowed by written permission of the original engine manufacturer; or (b) In the case of a Class I, Class IIA or Class IIB REC, replacement of an existing diesel oxidation catalyst providing that: (i) The requirements of paragraph 8.4 are met; and (ii) The retrofitted engine system meets at least the limits for the stage to which the base engine was approved for each of the other controlled pollutants relevant to that stage; (c) The installation of temperature and/or pressure measuring probes at the entrance of the NO reduction x REC system including the dosing unit.

The selected test engine shall comply in both series production condition and in retrofitted condition with all of the pollutant emissions limits associated with the stage or standard to which it was originally type- approved. Where vehicles or machines are fitted with on-board diagnostic systems those systems shall not be affected with respect to their monitoring function after the retrofit system has been installed. The characteristics of the electronic engine control unit (as regards, for example, injection timing, air-mass flow metering, or exhaust emissions reduction strategies) shall not be altered by the retrofitting. Any modification of the test engine that changes the original emission behaviour (for example alternation of the injection timing) is not permitted. 13. SPECIFICATIONS CONCERNING EMISSIONS MEASUREMENT 13.1. The gaseous and particulate components emitted by the engine or engine system in combination with the REC submitted for testing shall be measured by the methods described in the applicable annexes of Regulation No 49 and Regulation No 96. 13.2. If a heated chemiluminescent detector (CLD) is used for the determination of NO in accordance with 2 paragraph 8.4 of this Regulation, two parallel measuring chambers to determine NO and NO simultan­ x eously shall be used. Two CLDs in parallel are permitted providing that they both comply with the requirements of Regulation No 49 or Regulation No 96 as appropriate, and the absolute converter efficiencies are shown to be within 3 per cent of each other. 14.

If the applicant can show that a distance shorter than the minimum distance specified here will be used in all subsequent applications of the REC, the length of the pipe used in the test cell may be correspondingly reduced. Insulation or similar means of maintaining the exhaust temperature are permissible only if they will also be used in the subsequent installation of the REC on the vehicle or machine. 15. NO REDUCTION REC FAMILY x 15.1. The approval of a NO reduction REC will continue to be valid for a nominally similar system (employing x the same NO reduction technology) in a different configuration or application provided that it does not x deviate from the tested system with respect to the following features: (a) Critical dimensions of the active elements of the device (such as the size of valves or ducts, or the volume of a catalytic element, and including any reagent mixing device) shall be the same as those on the tested device, or shall not differ from those dimensions in the tested device by an amount greater than can be justified as insignificant by relevant tests or robust engineering analysis.

This condition will be considered to have been met if the introduction point is at least the same distance from inlet of the catalyst as the tested device and the means of reagent introduction (for example, air assisted or not) and any mixing device are also the same. 15.2. When testing the NO reduction REC in an engine test cell, the REC shall be fitted so that there is x a distance of at least 2 metres from the outlet of the turbocharger (turbine), or the exit flange of the exhaust manifold in the case of an engine not fitted with a turbocharger, to the REC inlet.

The REC manufacturer shall demonstrate to the Type Approval Authority. The existence of adequate procedures to select, train and monitor authorised REC installers. 21. MODIFICATION AND EXTENSION OF APPROVAL OF A REC 21.1. Every modification relevant in the context of this Regulation of the REC shall be notified to the Type Approval Authority, which granted the REC type approval.

The first two digits of the type- approval number indicate that the approval was granted in accordance with the requirements of Regulation No 132 in the form amended by this series. The approval mark shall also show the Class of REC (I, IIA, IIB, III or IV).27.4.2018 EN Official Journal of the European Union L 109/129 ANNEX 5 TEST OF A PARTICULATE REDUCTION REC (CLASS I OR II REC) Testing of a particulate reduction REC is performed in the following series of stages, including an assessment of the emissions of secondary pollutants and determination of the NO emissions: 2 1. PERFORMANCE OF A SERVICE ACCUMULATION RUN The service accumulation run shall be performed in accordance with the requirements of paragraph 9 of this Regulation. 2. ESTABLISHMENT OF ENGINE BASELINE EMISSIONS AND SPECIFIC FUEL CONSUMPTION WITHOUT REC FITTED 2.1. The engine baseline emissions are established by performance of an emissions test on the engine system without the REC in accordance with the requirements of Regulation No 49 or Regulation No 96, as appropriate to the application and type approval level of the base engine. 2.2. To enable the determination of reduction efficiency the emissions are additionally established by performance of an emissions test in accordance with the requirements of paragraph 8.3 of this Regulation. 2.3. The specific fuel consumption (g/kWh) shall be established by performance of the emissions test in paragraph 2.2 of this annex. 3. DETERMINATION OF EMISSIONS, FUEL CONSUMPTION AND REDUCTION EFFICIENCY WITH THE REC FITTED AFTER SERVICE ACCUMULATION RUN 3.1. The emissions are determined by performance of an emissions test in accordance with the requirements of Regulation No 49 or Regulation No 96, as appropriate to the intended application and intended emission level of the candidate REC with the REC fitted in accordance with the requirements of this Regulation. 3.2. For determination of reduction efficiency the emissions are additionally established by performance of an emissions test with the REC fitted in accordance with the requirements of paragraph 8.3 of this Regulation. 3.3. The specific fuel consumption (g/kWh) shall be established by performance of the emissions test in paragraph 3.2 of this annex. 4. DETERMINATION OF PARTICULATE REDUCTION REC REGENERATION STRATEGY AND REGENERATION CHARACTER­ ISTICS 4.1. The particulate reduction REC regeneration strategy (periodically or continuously) and the regeneration charac­ teristics are established by use of the following procedure. 4.2. In order to assess the regeneration performance of a particulate reduction REC at least 25 test cycles shall be carried out. The test cycle used shall be a cycle appropriate to the emissions stage or standard that the REC system is intended to permit the vehicle or machine to meet. The gaseous emissions and the particulate mass, and the particle number when appropriate, shall be measured during at least each fifth test cycle. A separate test of the particulate reduction system is carried out for each family or application range defined in the type approval procedure for the engine with which the REC system is intended to be used. That is, one system test takes place for each application area. 4.3. A particulate reduction REC is considered to have been proved to have a continuously operating regeneration process if a suitable assessment variable can be regarded as constant over at least 25 applicable test cycles. The average particulate emission and the average exhaust gas backpressure are regarded as suitable assessment variables for this purpose. If an applicant wishes to use one or more different assessment variables, he shall present a robust technical case to the Type Approval Authority in support of his request to do so. Where a continuously regenerating system as defined above also contains provision for active regeneration, then the assessment criteria defined in paragraph 4.6 of this annex shall be applied.L 109/130 EN Official Journal of the European Union 27.4.2018 The PM mass emission and the exhaust gas backpressure are considered constant within the meaning of this Regulation where there is a coefficient of variance of less than 25 per cent over 25 test cycles. The exhaust gas backpressure is measured continuously for the purposes of this assessment and the particulate emissions are measured during at least every fifth test cycle. The coefficient of variance (CoV) is calculated as follows: Standard deviation XðnÞ Coefficient of variance¼ Average value XðnÞ With: sffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi P P n x2 − ð xÞ2 Standard deviation¼ nðn − 1Þ and: Average value = (x + x + … + x )/n 1 2 n Where: n = number of measured values x = respective single measured value 4.4. Test of the regeneration characteristic of a particulate reduction REC This testing is carried out by loading the system with particulate matter until a constant exhaust gas backpressure is reached or over a time period of a maximum of 100 hours if no constant value for the backpressure has been achieved before that time. The exhaust gas backpressure is considered constant if, when measured after a period of at least 50 hours, the exhaust gas backpressure does not vary by more than plus or minus 4 mbar within a period of 30 min. The test points of the cycle used for loading the system are to be selected so that a maximum exhaust gas temperature of 180 °C at the inlet of the particulate reduction system is not exceeded. The loading of the system with particulate matter is preferably carried out by running the test engine at a constant speed of between 50 per cent and 75 per cent of its rated speed. After the REC has been loaded with particulate matter until the backpressure is constant, or after a maximum of 100 hours of running to load the system as defined above, regeneration is activated. This can, for example, be activated by running the engine at a higher load mode step so as to increase the exhaust temperature. After completion of the regeneration, exhaust gas measurements are to be taken during at least three iterations of the appropriate test cycle (That is, three ESC cycles, ETC cycles, WHSC cycles, WHTC cycles, NRSC cycles, or NRTC cycles.) The measured exhaust gas pollutant values shall not deviate from the measured exhaust gas pollutant values before the REC loading procedure by more than 15 per cent for the gaseous emissions or more than 20 per cent for the particulate mass or particle number. The manufacturer shall confirm in writing that the maximum temperatures occurring during the regeneration process will not damage or significantly shorten the effective life of the REC. As an alternative to using the loading procedure described above, the manufacturer may provide a particulate reduction REC already loaded to the limit for the regeneration test. 4.5. Assessment criteria for continuously regenerating particulate reduction REC The REC system test of the particulate reduction REC is considered satisfactory if the particulate emissions measured as defined in paragraph 8 of this Regulation are met. 4.5.1. Regulated pollutants The emissions of the regulated pollutants are determined by measurements taken immediately after the tests to establish the regeneration characteristics. The emissions of the regulated pollutants (CO, HC, PM and NO) in the initial condition and in the retrofitted x condition shall be within the limit values for the emissions stage or standard for which the engine was originally type-approved. The NO to NO ratio for the initial condition and the retrofitted condition is to be 2 x recorded and shown in the test report.27.4.2018 EN Official Journal of the European Union L 109/131 The determination of the NO and NO mass emissions is to be determined by simultaneous measurement in 2 x accordance with paragraph 13.2 of this Regulation. 4.6. Assessment criteria for periodically regenerating particulate reduction REC This provision only applies to REC which utilise active regeneration. The emissions shall be measured during at least three appropriate hot-start test cycles (That is, three hot-start ESC cycles, ETC cycles, WHSC cycles, WHTC cycles, NRSC cycles, or NRTC cycles.) One of the cycles from which measurements are taken should include a regeneration event on a stabilized REC system. The other two cycles from which measurements are taken should be cycles in which regeneration does not occur. If regeneration takes longer than one test cycle, consecutive test cycles shall be run until regeneration is complete. The REC manufacturer shall declare the conditions under which the regeneration process normally occurs (the particulate loading, temperature, exhaust back-pressure, or other relevant parameters). The manufacturer shall also provide the frequency of the regeneration event in terms of the fraction of tests during which the regeneration occurs. The exact procedure used to determine this fraction shall be agreed with the manufacturer by the Type Approval Authority on the basis of good engineering judgement. (This frequency fraction is the factor F in the procedure for calculation of nominal particulate emissions set out below.) For a regeneration test, the manufacturer shall provide a particulate reduction REC system that has been loaded with particulate matter. As an option, the manufacturer may run consecutive test cycles as set out in paragraph 4.4 of this annex until the particulate reduction REC is loaded. Emissions measurement is not required on cycles run for the purposes of loading the REC with particulate matter. Average emissions between regeneration phases shall be determined from the arithmetic mean of several tests approximately equidistant in terms of the number of unmeasured test cycles between them. As a minimum, at least one test cycle as close as possible prior to a regeneration test and one test cycle immediately after a regeneration test shall be included in the calculation of the arithmetic mean. During the regeneration test, all the data needed to detect regeneration shall be recorded (CO or NO emissions, x temperature before and after the REC, exhaust back pressure, and any other relevant parameters). It is permissible for the applicable emission limits to be exceeded during the regeneration process. The test procedure is shown schematically in the figure below. Scheme of periodic regenerationL 109/132 EN Official Journal of the European Union 27.4.2018 The system test of a periodically regenerating particulate reduction REC is considered passed if the nominal particulate emissions calculated using the procedure set out below are within the limit set for the reduction level for which the applicant wishes the REC to be approved. 4.6.1. Regulated pollutants The emissions of regulated pollutants (CO, HC, PM and NO) shall not exceed the limit values for the standard x to which the engine was originally type approved, both in the initial condition and in the retrofitted condition. The NO /NO ratio for both the initial condition and the retrofitted condition are to be recorded and shown in 2 x the test report. The determination of the NO and NO-mass emissions is to be determined by simultaneous measurement in 2 x accordance with paragraph 4.7.2 of this annex and paragraph 13 of this Regulation. 4.6.1.1. Weighted particulate emissions The particulate emissions PM mass (g/kWh) for periodically regenerating systems are determined as follows. PM mass = PM mass × F + (1 – F) × PM mass r wor Where: F = frequency of the regeneration event in terms of fraction of tests during which the regeneration occurs [-] PM mass = average specific emission from a test in which the regeneration does not occur [g/kWh] wor PM mass = average specific emission from a test in which the regeneration occurs [g/kWh] r The manufacturer may choose, on the basis of good engineering analysis, to calculate either a multiplicative or an additive regeneration adjustment factor k, expressing the average emission rate, as follows: r k = PM mass/PM mass (multiplicative adjustment factor) r wor or k = PM mass – PM mass (upward adjustment factor) Ur wor or k = PM mass – PM mass (downward adjustment factor) Dr r If more than two measurements between the regeneration phases are used to determine the emissions, these further measurements shall be taken at equal intervals and an arithmetical average taken. 4.6.1.2. Weighted gaseous emissions The emission of gaseous components Mgas (g/kWh) for periodically regenerating systems is determined as follows. Mgas = Mgas × F + (1 – F) × Mgas r wor Where: F = frequency of the regeneration event in terms of the fraction of tests during which the regeneration occurs Mgas = average specific emission from a test in which the regeneration does not occur [g/kWh] wor Mgas = average specific emission from a test in which the regeneration occurs [g/kWh] r The manufacturer may choose, on the basis of good engineering analysis, to calculate either a multiplicative or an additive the regeneration adjustment factor k, expressing the average emission rate, as follows: r k = Mgas/Mgas (multiplicative adjustment factor) r wor or k = Mgas – Mgas (upward adjustment factor) Ur wor or k = Mgas – Mgas (downward adjustment factor) Dr r27.4.2018 EN Official Journal of the European Union L 109/133 4.7. Determination of NO emissions 2 The testing shall be performed on the test engine selected by the criteria described in paragraph 12 of this Regulation. 4.7.1. Selection of the particulate reduction REC for NO determination. 2 The REC used for testing may be different from the REC used in paragraph 4.5 of this annex. The particulate reduction REC to be tested shall be: (a) A particulate reduction REC with the largest active volume and, if a diesel oxidation catalyst (DOC) is used upstream, the catalytic converter with the largest active surface area and (b) The particulate reduction REC containing the maximum charge of platinum with the maximum total charge of catalytically active material within the defined REC family. The chosen particulate reduction REC shall be fitted in such a way that the shortest distance between the engine and the particulate reduction REC, as specified in the application range for the particulate reduction REC, is achieved. The particulate reduction REC shall be unloaded and shall not have been run in for longer than 125 hours. 4.7.2. Determination of NO emissions 2 Three successive WHTC or NRTC test cycles, as appropriate to the application, shall be conducted. The emissions shall be determined over all three cycles and averaged. If the range of these results is greater than ± 15 per cent of the mean, then an additional test cycle should be run. The calculation of the NO and NO emissions shall be determined for CI engines used in vehicles of category x 2 M and N over the complete WHTC cycle. For CI engines used in non-road mobile machinery or Category T vehicles having an installed net power higher than 18 kW, but not more than 560 kW the calculation of the NO and NO emissions shall be determined x 2 over the complete NRTC cycle. 5. TEST CYCLES 5.1. In cases where the approval of the engine with which the REC is to be used is an on-road approval (performed in accordance with Regulation No 49) the test cycle to be used for approval of the REC shall be the test cycle associated with the emissions stage in Regulation No 49 for which approval of the REC is being sought. 5.2. Where the engine is being used in an on-road application and has an approval issued in accordance with the requirements of Regulation No 49, the test cycle to be used for the establishment of the base emissions of the engine shall be the test cycle associated with the emissions stage in Regulation No 49 for which the engine has an approval. 5.3.

The manufacturer shall specify a minimum acceptable reagent concentration CDmin, which results in tailpipe NO emissions not exceeding x (a) 0,9 g/kWh for retrofitted engine systems complying with the NO emission limit for stage Q and R of x Regulation No 96; or (b) The NO emission limit + 1,5 g/kWh for all other systems. x 8.2.1. The correct value of CDmin shall be demonstrated during type approval as follows and recorded in the documentation package as specified in Annex 1. 8.2.1.1. The test shall be conducted by performing the hot part of the WHTC or NRTC cycle, whichever applies, using a reagent with the concentration CDmin.27.4.2018 EN Official Journal of the European Union L 109/149 8.2.1.2. A WHTC or NRTC preconditioning cycle or REC manufacturer defined pre-conditioning cycle may be conducted, permitting a closed loop NO control system to perform adaptation to the quality of the reagent x with the concentration CDmin. 8.2.1.3. The NO emission resulting from this test shall be lower than the NO threshold specified in paragraph 8.2 of x x this annex. 8.2.2. Any reagent concentration lower than CDmin shall be detected and be regarded, for the purpose of paragraph 8.1 of this annex, as being incorrect reagent. 8.3. A specific counter (‘the reagent quality counter’) shall be attributed to the reagent quality. The reagent quality counter shall count the number of operating hours with an incorrect reagent. 8.3.1. Optionally, the manufacturer may group the reagent quality failure together with the failures listed in paragraphs 9 and 10 of this annex into a single counter. 8.4. Activation of the operator warning system 8.4.1. The operator warning system shall be activated in accordance with paragraph 4 of this annex. 8.4.2. When the operator warning system includes a message display system, it shall display a message indicating the reason of the warning if technically feasible (for example ‘incorrect urea detected’, ‘incorrect AdBlue detected’, or ‘incorrect reagent detected’). 8.5. Activation of the operator inducement system 8.5.1. The operator inducement system shall be activated in accordance with paragraph 5 of this annex. 9. REAGENT DOSING ACTIVITY 9.1. The engine shall include a means of determining interruption of dosing. 9.2. A specific counter shall be attributed to the dosing activity (the ‘dosing activity counter’). The counter shall count the number of operating hours which occur with an interruption of the reagent dosing activity. This is not required where such interruption is demanded because vehicle or machine operating conditions are such that their emission performance does not require reagent dosing. 9.2.1. Optionally, the REC manufacturer may group the reagent dosing failure together with the failures listed in paragraphs 8 and 10 of this annex into a single counter. 9.3. Activation of the operator warning system 9.3.1. The operator warning system shall be activated in accordance with paragraph 4 of this annex. 9.3.2. When the warning system includes a message display system, it shall display a message indicating the reason of the warning (e.g. ‘urea dosing malfunction’, ‘AdBlue dosing malfunction’, or ‘reagent dosing malfunction’). 9.4. Activation of the operator inducement system 9.4.1. The operator inducement system shall be activated in accordance with paragraph 5 of this annex. 10. MONITORING FAILURES THAT MAY BE ATTRIBUTED TO TAMPERING 10.1. In addition to the level of reagent in the reagent tank, the reagent quality, and the interruption of dosing, the following failures shall be monitored because they may be attributed to tampering: (a) Disconnect reagent dosing valve; (b) Disconnect reagent pump; (c) Failures or disconnect of the NCD system, as described in paragraph 10.1.1 of this annex.L 109/150 EN Official Journal of the European Union 27.4.2018 10.1.1. The NCD system shall be monitored for electrical failures and for removal or deactivation of any sensor that prevents it from diagnosing any other failures mentioned in paragraphs 7 to 9 of this annex. A non-exhaustive list of sensors that affect the diagnostic capability are those directly measuring NO concen­ x tration, urea quality sensors, ambient sensors and sensors used for monitoring reagent dosing activity, reagent level, or reagent consumption. 10.2. A specific counter shall be attributed to each of the monitoring failures considered in paragraph 10.1 of this annex. The NCD system counters shall count the number of operating hours when the diagnostic capability of the NCD system is not available. Grouping of several faults into a single counter is permitted. 10.2.1. Optionally, the manufacturer may group the NCD system failure together with the failures listed in paragraphs 8 and 9 of this annex into a single counter. 10.3. As an alternative to the requirements in paragraph 10.1 of this annex, the manufacturer may use a NO x sensor located in the exhaust gas. In this case: (a) The NO value shall not exceed the lower threshold between: x (i) Twice the applicable REC type approval NO limit; or x (ii) An increase of no more than 1 g/kWh above the applicable REC type approval NO limit; x (b) A single failure ‘high NO - root cause unknown’ may be used. x 10.4. Activation of the operator warning system 10.4.1. The operator warning system shall be activated in accordance with paragraph 4 of this annex. 10.4.2. When the warning system includes a message display system, it shall display a message indicating either the reason of the warning (for example ‘reagent dosing valve disconnected’, or ‘critical emission failure’). 10.5. Activation of the operator inducement system 10.5.1. The operator inducement system shall be activated in accordance with paragraph 5 of this annex. 11. DEMONSTRATION REQUIREMENTS 11.1. The compliance to the requirements of this annex shall be demonstrated during type-approval by performing: (a) A demonstration of the operator warning system activation; (b) A demonstration of the operator inducement system activation. 11.2. Demonstration of the operator warning system activation. 11.2.1. The compliance of the warning system activation shall be demonstrated by performing two tests: lack of reagent, and one failure category considered in paragraphs 8 to 10 of this annex. 11.2.2. For the purpose of demonstrating the activation of the warning system in case of a wrong reagent quality, a reagent shall be selected with a dilution of the active ingredient at least as dilute as that communicated by the manufacturer (CDmin) according to the requirements of paragraph 8.2 of this annex 11.2.3. For the purpose of demonstrating the activation of the operator warning system, the selection shall be performed on the basis of a list of potential failures provided by the REC manufacturer to the Type Approval Authority, and agreed by the Type Approval Authority. 11.2.4. For the purpose of this demonstration, a separate test shall be performed for each of the failures considered in paragraph 11.2.1 of this annex. 11.2.5. During a test, no failure shall be present other than the one addressed by the test. 11.2.6. Prior to starting a test, all failure messages shall have been erased.27.4.2018 EN Official Journal of the European Union L 109/151 11.2.7. At the request of the manufacturer, and with the agreement of the Type Approval Authority, the failures subject to testing may be simulated. 11.2.8. Demonstration test procedure for failures other than lack of reagent 11.2.8.1. Once the failure has been installed or simulated, the NCD system shall respond to the introduction of a failure within three consecutive hot WHTC or hot NRTC cycles, as applicable. 11.2.8.2. Each individual test cycle in the demonstration test may be separated by an engine shut-off. 11.2.9. Demonstration test procedure in case of lack of reagent 11.2.9.1. The REC system shall be operated over one or more hot WHTC or hot NRTC cycles, as applicable, at the discretion of the REC manufacturer. 11.2.9.2. The demonstration shall start with a level of reagent in the tank to be agreed between the REC manufacturer and the Type Approval Authority but representing not less than 10 per cent of the nominal capacity of the tank. 11.2.10. The demonstration of the warning system activation is deemed to be accomplished if, at the end of each demonstration test performed according to paragraphs 11.2.8 and 11.2.9 of this annex, the warning system has been properly activated in accordance with paragraph 4 of this annex. 11.2.11. The manufacturer shall be permitted to simulate, in agreement with the Type Approval Authority, the achievement of a certain number of operating hours. 11.3. Demonstration of the operator inducement system activation 11.3.1. The demonstration of the operator inducement system shall be done by tests performed on an engine test bench. 11.3.2. If the REC manufacturer chooses, and subject to the agreement of the Type Approval Authority, the demonstration tests may be performed on a complete vehicle or machine either by mounting the vehicle or machine on a suitable test bed or by running it on a test track under controlled conditions. 11.3.3. The compliance of the inducement system activation shall be demonstrated by performing two tests: lack of reagent, and one failure category considered in paragraphs 8 to 10 of this annex. 11.3.4. For the purpose of this demonstration, the failures selected for the warning system activation shall be used. 11.3.5. The demonstration starts when the warning system has been activated as a result of the detection of a failure selected by the Type Approval Authority. 11.3.6. When the system is being checked for its reaction to the case of lack of reagent in the tank, the engine shall be run until the reagent tank is empty, or has reached the level of 2,5 per cent of the nominal full capacity of the tank or the value declared by the manufacturer in accordance with paragraph 7.3.1 of this annex. 11.3.6.1. The manufacturer may, with the agreement of the Type Approval Authority, simulate continuous running by extracting reagent from the tank, either whilst the engine is running or is stopped. 11.3.7. When the system is checked for its reaction in the case of a failure other than a lack of reagent in the tank, the engine shall be run for the relevant number of hours indicated in paragraph 5.2 of this annex. 11.3.8. The manufacturer shall be permitted to simulate, in agreement with the Type Approval Authority, the achievement of a certain number of operating hours. 11.3.9. The demonstration of the inducement system activation is deemed to be accomplished if, at the end of each demonstration test performed according to paragraphs 11.3.4 and 11.3.5 of this annex, the inducement system has been properly activated in accordance with paragraph 5 of this annex.L 109/152 EN Official Journal of the European Union 27.4.2018 ANNEX 11 INSTALLATION AND OPERATING INSTRUCTIONS 1. The REC manufacturer shall provide written information and installation instructions for use by retrofitters, and operating and maintenance instructions for use by owners and operators.
