8.2.1.1.


When the type approval authority determines that the quality of production seems unsatisfactory, a vehicle shall be randomly taken from the family and subjected to the tests described in Annex 6.












8.2.1.2.


The production shall be deemed to conform if this vehicle meets the requirements of the tests described in Annex 6.












8.2.1.3.


If the vehicle tested does not satisfy the requirements of paragraph 8.2.1.1 a further random sample of four vehicles shall be taken from the same family and subjected to the tests described in Annex 6. The tests may be carried out on vehicles which have completed a maximum of 15 000 km with no modifications.












8.2.1.4.


The production shall be deemed to conform if at least three vehicles meet the requirements of the tests described in Annex 6.




9.   In-service conformity








9.1.


Measures to ensure in-service conformity of vehicles type-approved under this Regulation shall be taken in accordance with Annex 4 to this Regulation.












9.2.


The in-service conformity checks shall be appropriate for confirming that tailpipe and evaporative emissions are effectively limited during the normal life of vehicles under normal conditions of use.












9.3.


In-service conformity shall be checked on properly maintained and used vehicles, in accordance with Appendix 1 of Annex 4, between 15 000 km or 6 months whichever occurs later and 100 000 km or 5 years whichever occurs sooner. In-service conformity for evaporative emissions shall be checked on properly maintained and used vehicles, in accordance with Appendix 1 of Annex 4, between 30 000 km or 12 months whichever occurs later and 100 000 km or 5 years whichever occurs sooner.
The requirements for in-service conformity checks are applicable until 5 years after the last vehicles of that in-service conformity family are registered.












9.4.


In-service conformity checks shall not be mandatory if the annual production volume of an in-service conformity family intended for sales in the Contracting Parties that apply this regulation was less than 5 000 vehicles for the previous year. For the European Union, this shall apply for the whole Union. For such families, the manufacturer shall provide the type approval authority with a report of any emissions related warranty and relevant repair as set out in paragraph 4 of Annex 4. Such in-service conformity families may still be selected to be tested in accordance with Annex 4.












9.5.


The manufacturer and the granting type approval authority shall perform in-service conformity checks in accordance with Annex 4. Other type approval authorities, technical services and other actors may perform parts of the in-service conformity checks in accordance with Annex 4.












9.6.


The granting type approval authority shall take the decision on whether a family failed the provisions of in-service conformity, following a compliance assessment and approve the plan of remedial measures presented by the manufacturer in accordance with Annex 4.












9.7.


If a type approval authority, technical service or other actors have established that an in-service conformity family fails the in-service conformity check, it shall notify without delay the granting type approval authority.
Following that notification the granting type approval authority shall inform the manufacturer that an in-service conformity family fails the in-service conformity checks and that the procedures laid out in paragraphs 6 and 7 of Annex 4 shall be followed.












9.8.


The manufacturer shall ensure that, throughout the normal life of a vehicle which is type approved in accordance with UN Regulation No 154, its final RDE emission results as determined in accordance with UN Regulation No 168 on RDE and emitted at any RDE test performed in accordance with that Regulation, do not exceed the emission limits for NOX and PN.




10.   Penalties for non-conformity of production








10.1.


The approval granted in respect of a vehicle type pursuant to this Regulation, may be withdrawn if the requirements laid down in paragraph 8.1 are not complied with or if the vehicle or vehicles taken fail to pass the tests prescribed in paragraph 8.1.1.












10.2.


If a Contracting Party which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation, by means of a communication form conforming to the model in Annex 2 to this Regulation.




11.   Production definitively discontinued
If the holder of the approval completely ceases to manufacture a type of vehicle approved in accordance with this Regulation, he shall so inform the type approval authority which granted the approval.

Extended Documentation Package
The extended documentation package shall include the following information on all AES:






(a)


a declaration of the manufacturer that the vehicle does not contain any defeat device not covered by one of the exceptions in paragraph 5.1.3 of this Regulation;










(b)


a description of the engine and the emission control strategies and devices employed, whether software or hardware, and any condition(s) under which the strategies and devices will not operate as they do during testing for TA;










(c)


a declaration of the software versions used to control these AES/BES, including the appropriate checksums or reference values of these software versions and instructions to the authority on how to read the checksums or reference values; the declaration shall be updated and sent to the type approval authority that holds this extended documentation package each time there is a new software version that has an impact to the AES/BES. Manufacturers may request to use an alternative to a checksum as long as it provides an equivalent level of traceability for software version changes;










(d)


detailed technical reasoning of any AES estimating the impact with the AES and without it, and information on the following:






(i)


why any of the exception clauses from the defeat device prohibition in paragraph 5.1.3 of this Regulation apply;










(ii)


hardware element(s) that need to be protected by the AES, where applicable;










(iii)


proof of sudden and irreparable engine damage that cannot be prevented by regular maintenance and would occur in the absence of the AES, where applicable;










(iv)


a reasoned explanation on why there is a need to use an AES upon engine start, where applicable;














(e)


a description of the fuel system control logic, timing strategies and switch points during all modes of operation;










(f)


a description of the hierarchical relations among the AES (i.e. when more than one AES can be active concurrently, an indication of which AES is primary in responding, the method by which strategies interact, including data flow diagrams and decision logic and how does the hierarchy assure emissions from all AES are controlled to the lowest practical level;










(g)


a list of parameters which are measured and/or calculated by the AES, along with the purpose of every parameter measured and/or calculated and how each of those parameters relates to engine damage; including the method of calculation and how well these calculated parameters correlate with the true state of the parameter being controlled and any resulting tolerance or factor of safety incorporated into the analysis;










(h)


a list of engine/emission control parameters which are modulated as a function of the measured or calculated parameter(s) and the range of modulation for each engine/emission control parameter; along with the relationship between engine/emission control parameters and measured or calculated parameters;










(i)


an evaluation of how the AES will control real-driving emissions to the lowest practical level, including a detailed analysis of the expected increase of total regulated pollutants and CO2 emissions by using the AES, compared to the BES.
The extended documentation package shall be limited to 100 pages and shall include all the main elements to allow the type approval authority to assess the AES. The package may be complemented with annexes and other attached documents, containing additional and complementary elements, if necessary. The manufacturer shall send a new version of the extended documentation package to the type approval authority every time changes are introduced to the AES. The new version shall be limited to the changes and their effect. The new version of the AES shall be evaluated and approved by the type approval authority.

Appendix 3b
Methodology for the assessment of AES
The assessment of the AES by the type approval authority shall include at least the following verifications:






1.


The increase of emissions induced by the AES shall be kept at the lowest possible level:






(a)


The increase of total emissions when using an AES shall be kept at the lowest possible level throughout the normal use and life of the vehicles;










(b)


Whenever a technology or design that would allow for improved emission control is available on the market at the time of the AES preliminary assessment it shall be used with no unjustified modulation.














2.


When used to justify an AES, the risk of sudden and irreparable damage to the ‘propulsion energy converter and the drivetrain’, as defined in Mutual Resolution No 2 (M.R.2) of the 1958 and 1998 Agreements of UNECE containing Vehicle Propulsion System Definitions (13), shall be appropriately demonstrated and documented, including the following information:






(a)


Proof of catastrophic (i.e. sudden and irreparable) engine damage shall be provided by the manufacturer, along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;










(b)


When a technology or design is available on the market at the time of the AES application that eliminates or reduces that risk, it shall be used to the largest extent technically possible (i.e. with no unjustified modulation);










(c)


Durability and the long-term protection of the engine or components of the emission control system from wear and malfunctioning shall not be considered an acceptable reason to grant an exemption from the defeat device prohibition.














3.


An adequate technical description shall document why it is necessary to use an AES for the safe operation of the vehicle:






(a)


Proof of an increased risk to the safe operation of the vehicle should be provided by the manufacturer along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;










(b)


When a different technology or design is available on the market at the time of the AES application that would allow for lowering the safety risk, it shall be used to the largest extent technically possible (i.e. with no unjustified modulation).














4.


An adequate technical description shall document why it is necessary to use an AES during engine start:






(a)


Proof of the need to use an AES during engine start shall be provided by the manufacturer along with a risk assessment which includes an evaluation of the likelihood of the risk occurring and severity of the possible consequences, including results of tests carried out to this effect;










(b)


Where a different technology or design is available on the market at the time of the AES application that would allow for improved emission control upon engine start, it shall be used to the largest extent technically possible.

ANNEX 4
In-service conformity methodology
1.   Introduction
This Annex sets out the in-service conformity (ISC) methodology for checking compliance against the emission limits for tailpipe (including low temperature) and evaporative emissions throughout the normal life of the vehicle.
2.   Process description

Figure 4/1


Illustration of the in-service conformity process













Note:


GTAA refers to the granting type approval authority, OEM refers to the manufacturer, and Other Actors are defined as: TAA refers to type approval authorities other than the one granting the relevant type approval, TS refer to Technical services, other CP to Contracting Parties not issuing the type approval, and third parties.




3.   ISC family definition
An ISC family shall be composed of the following vehicles:






(a)


For tailpipe emissions (Type 1, RDE and Type 6 tests), the vehicles covered by the PEMS test family, as described in paragraph 6.3.1 of UN Regulation No 168 on RDE,










(b)


For evaporative emissions (Type 4 test), the vehicles included in the evaporative emission family, as described in paragraph 6.6.3 of UN Regulation No 154.




4.   Information gathering and initial risk assessment
The granting type approval authority and other actors shall gather all relevant information on possible emission non-compliances relevant for deciding which ISC families to check in a particular year. They shall take into account in particular, information indicating vehicle types with high emissions in real driving conditions. That information shall be obtained by appropriate methods, which may include remote sensing, simplified on-board emissions monitoring systems (SEMS) and testing with PEMS. The number and importance of exceedances observed during such testing may be used to prioritise ISC testing.
As part of the information provided for the ISC checks, each manufacturer shall report to the granting type approval authority on emission-related warranty claims, and any emission-related warranty repair works performed or recorded during servicing, in accordance with a format agreed between the granting type approval authority and the manufacturer at type approval. The information shall detail the frequency and nature of faults for emissions-related components and systems by ISC family. The ISC reports shall be filed at least once a year for each ISC family for the duration of the period during which in-service conformity checks are to be performed in accordance with paragraph 9.3 of this Regulation. The ISC reports shall be made available upon request.
On the basis of the information referred to in the first and second paragraphs, the granting type approval authority shall make an initial assessment of the risk of an ISC family to not comply with the in-service conformity rules and on that basis shall take a decision on which families to test and which types of tests to perform under the ISC provisions. Additionally, the granting type approval authority may randomly choose ISC families to test.
Other actors shall take into account the information collected according to the first paragraph in order to prioritise testing. Additionally, they may randomly choose ISC families to test.
5.   ISC testing
The manufacturer shall perform ISC testing for tailpipe emissions comprising at least the Type 1 test for all ISC families. The manufacturer may also perform RDE, Type 4 and Type 6 tests for all or part of the ISC families. The manufacturer shall report to the granting type approval authority all results of the ISC testing for in-service conformity.
The granting type approval authority shall check an appropriate number of ISC families each year, as set out in paragraph 5.4.
Other actors may perform checks on any number of ISC families each year. They shall report to the granting type approval authority all results of the ISC testing.
5.1.   Quality assurance of testing
The granting type approval authority shall annually audit the ISC checks performed by the manufacturer. The granting type approval authority may also audit the ISC checks performed by other actors. The audit shall be based on the information provided by the manufacturers, or other actors, which shall include at least the detailed ISC report in accordance with Appendix 3. The granting type approval authority may require the manufacturers, or other actors to provide additional information.
5.2.   Disclosure of tests results
The granting type approval authority shall communicate the results of the compliance assessment and remedial measures for a particular ISC family to other actors which provided test results for that family as soon as they become available.
The results of the tests, including the detailed data for all vehicles tested, may only be disclosed to the public after the publication by the granting type approval authority of the annual report or the results of an individual ISC procedure or after the closure of the statistical procedure (see paragraph 5.10) without a result. If the results of the ISC tests undertaken by other actors are published, reference shall be made to the annual report by the granting type approval authority which included them.
5.3.   Types of tests
ISC testing shall only be performed on vehicles selected in accordance with Appendix 1.
ISC testing with the Type 1 test shall be performed in accordance with UN Regulation No 154.
ISC testing with the RDE test shall be performed in accordance with UN Regulation No 168 on RDE, Type 4 tests shall be performed in accordance with Appendix 2 to this Annex and Type 6 tests shall be performed in accordance with Annex 8.
5.4.   Frequency and scope of ISC testing
The time period between commencing two in-service conformity checks by the manufacturer for a given ISC family shall not exceed 24 months.
The frequency of ISC testing performed by the granting type approval authority shall be based on a risk assessment methodology consistent with the international standard ISO 31000:2018 – Risk Management – Principles and guidelines which shall include the results of the initial assessment made according to paragraph 4.
Each granting type approval authority shall perform both the Type 1 and RDE tests on a minimum of 5 per cent of the ISC families per manufacturer per year or at least two ISC families per manufacturer per year, where available. The requirement for testing a minimum of 5 per cent or at least two ISC families per manufacturer per year shall not apply to small volume manufacturers. The granting type approval authority shall ensure the widest possible coverage of ISC families and vehicle age in a particular in-service conformity family in order to ensure compliance with paragraph 9.3 of this Regulation. The granting type approval authority shall complete the statistical procedure for each ISC family it has started within 12 months.
Type 4 or Type 6 ISC tests shall have no minimum frequency requirements.
5.5.   Funding for ISC testing by the granting type approval authorities
The granting type approval authority shall ensure that sufficient resources are available to cover the costs for in-service conformity testing. Without prejudice to national law, those costs shall be recovered by fees that can be levied on the manufacturer by the granting type approval authority. Such fees shall cover ISC testing of up to 5 per cent of the in-service conformity families per manufacturer per year or at least two ISC families per manufacturer per year.
5.6.   Testing plan
When performing testing for ISC, the granting type approval authority shall draft a testing plan. In the case of RDE testing, that plan shall include testing to check ISC compliance under a wide range of conditions in accordance with UN Regulation No 168 on RDE.
5.7.   Selection of vehicles for ISC testing
The information gathered shall be sufficiently comprehensive to ensure that in-service performance can be assessed for vehicles that are properly maintained and used. The tables in Appendix 1 shall be used to decide whether the vehicle can be selected for the purposes of ISC testing. During the check against the tables in Appendix 1, some vehicles may be declared as faulty and not tested during ISC, when there is evidence that parts of the emission control system were damaged.
The same vehicle may be used to perform and establish reports from more than one type of tests (Type 1, RDE, Type 4, Type 6) but only the first valid test of each type shall be taken into account for the statistical procedure.
5.7.1.   General requirements
The vehicle shall belong to an ISC family as described in paragraph 3 and shall comply with the checks set out in the table in Appendix 1. It shall be registered in the Contracting Party and have been driven in the Contracting Party for at least 90 per cent of its driving time. The emissions testing may be done in a different geographical region from that where the vehicles have been selected. In case of ISC testing conducted by the manufacturer, with the agreement of the granting type approval authority, vehicles registered in a non-Contracting Party may be tested, if they belong to the same ISC family and are accompanied by a certificate of conformity defined in the 1958 Agreement, Schedule 1 (E/ECE/TRANS/505/Rev.3).
The vehicles selected shall be accompanied by a maintenance record which shows that the vehicle has been properly maintained and has been serviced in accordance with the manufacturer’s recommendations with only original parts used for the replacement of emissions related parts.
Vehicles exhibiting indications of abuse, improper use that could affect its emissions performance, tampering or conditions that may lead to unsafe operation shall be excluded from ISC.
The vehicles shall not have undergone aerodynamic modifications that cannot be removed prior to testing.
A vehicle shall be excluded from ISC testing if the information stored in the on-board computer shows that the vehicle was operated after a fault code was displayed and a repair was not carried out in accordance with manufacturer specifications.
A vehicle shall be excluded from ISC testing if the fuel from the vehicle tank does not meet the applicable standards or if there is evidence or record of fuelling with the wrong type of fuel.
5.7.1.1.   Additional RDE related ISC requirements
For ISC or regional market surveillance testing purposes, the reference CO2 mass shall be obtained from the Certificate of Conformity for the individual vehicle. The value for OVC-HEV vehicles shall be obtained from the WLTP test conducted using the Charge Sustaining mode.
5.7.1.2.   Lubricating oil, fuel and reagent
For tests performed during ISC, or regional market surveillance the fuel used for RDE testing may be any fuel legally available in the market and within the specifications issued by the manufacturer for vehicle operation by the customer.
5.7.2.   Vehicle Examination and Maintenance
Diagnosis of faults and any normal maintenance necessary in accordance with Appendix 1 shall be performed on vehicles accepted for testing, prior to or after proceeding with ISC testing.
The following checks shall be carried out: OBD checks (performed before or after the test), visual checks for lit malfunction indicator lamps, checks on air filter, all drive belts, all fluid levels, radiator and fuel filler cap, all vacuum and fuel system hoses and electrical wiring related to the after-treatment system for integrity; checks on ignition, fuel metering and pollution control device components for maladjustments and/or tampering.
If the vehicle is within 800 km of a scheduled maintenance service, that service shall be performed.
The window washer fluid shall be removed before the Type 4 test and replaced with hot water.
A fuel sample shall be collected and kept in accordance with the requirements of UN Regulation No 168 on RDE for further analysis in case of fail.
All faults shall be recorded. When the fault is on the pollution control devices then the vehicle shall be reported as faulty and not be used further for testing, but the fault shall be taken into account for the purposes of the compliance assessment performed in accordance with paragraph 6.1.
5.8.   Sample size
When manufacturers apply the statistical procedure set out in paragraph 5.10 for the Type 1 test, the number of sample lots shall be set on the basis of the annual production volume of an in-service family intended for sale in the Contracting Parties that apply this regulation, as described in Table 4/1.

Each sample lot shall include enough vehicle types, in order to ensure that at least 20 % of the total registrations of this PEMS family in the Contracting Party for the previous year are covered. In case the same PEMS family is shared between more brands, then all brands shall be tested. When a family requires more than one sample lot to be tested, the vehicles in the second and third sample lots shall select vehicles used in different ambient and/or typical use conditions from those selected for the first sample.
5.9.   Access to data required for testing
The manufacturer shall complete the package on Testing Transparency in the format specified in Tables 1 and 2 of Appendix 5 and in Table A4/2 and transmit it to the granting type approval authority. Table 2 of Appendix 5 shall be used in order to allow the selection of vehicles from the same family for testing and along with Table 1 of Appendix 5 provide sufficient information for vehicles to be tested.
All information in Tables 1 and 2 of Appendix 5 shall be accessible to the public in an electronic form free of charge within 5 working days of the request.

5.10.   Statistical Procedure
5.10.1.   General
The verification of in-service conformity shall rely on a statistical method following the general principles of sequential sampling for inspection by attributes. The minimum sample size for a pass result is three vehicles, and the maximum cumulative sample size is ten vehicles for the Type 1 and RDE tests.
For the Type 4 and Type 6 tests a simplified method may be used, where the sample shall consist of three vehicles and shall be considered a fail if all three vehicles fail to pass the test, and a pass if all three vehicles pass the test. In cases where two out of three passed or failed, the type approval authority may decide to conduct further tests or proceed with assessing the compliance in accordance with paragraph 6.1.
Test results shall not be multiplied by deterioration factors.
Prior to the performance of the first ISC test, the manufacturer, or other actors shall notify the intent of performing in-service conformity testing of a given vehicle family to the granting type approval authority. Upon this notification, the granting type approval authority shall open a new statistical folder to process the results for each relevant combination of the following parameters for that particular party/or that pool of parties: vehicle family, emissions test type and pollutant. Separate statistical procedures shall be opened for each relevant combination of those parameters.
The granting type approval authority shall incorporate in each statistical folder only the results provided by the relevant party. The granting type approval authority shall keep a record of the number of tests performed, the number of failed and passed tests and other necessary data to support the statistical procedure.
Whereas more than one statistical procedure can be open at the same time for a given combination of test type and vehicle family, a party shall only be allowed to provide test results to one open statistical procedure for a given combination of test type and vehicle family. Each test shall be reported only once and all tests (valid, not valid, fail or pass, etc.) shall be reported.
Each ISC statistical procedure shall remain open until an outcome is reached when the statistical procedure arrives to a pass or fail decision for the sample in accordance with paragraph 5.10.5. However, if an outcome is not reached within 12 months of the opening of a statistical folder, the granting type approval authority shall close the statistical folder unless it decides to complete testing for that statistical folder within the following 6 months.
5.10.2.   Pooling of ISC results
Test results from other actors may be pooled for the purposes of a common statistical procedure. The pooling of test results shall require the written consent from all the interested parties providing test results to a pool of results, and a notification to the type approval authorities prior to the start of testing. One of the parties shall be designated as leader of the pool and be responsible for data reporting and communication with the granting type approval authority.
5.10.3.   Pass/Fail/Invalid outcome for a single test
An ISC emissions test shall be considered as ‘passed’ for one or more pollutants when the emissions result is equal or below the emission limit set out in paragraph 6.3.10 of UN Regulation No 154 for that type of test.
An emissions test shall be considered as ‘failed’ for one or more pollutants when the emissions result is greater than the corresponding emission limit for that type of test. Each failed test result shall increase the ‘f’ count (see paragraph 5.10.5) by 1 for that statistical instance.
An ISC emissions test shall be considered invalid if it does not respect the requirements of the tests referred to in paragraph 5.3. Invalid test results shall be excluded from the statistical procedure and the test shall be repeated with the same vehicle in order to have a valid test.
The results of all ISC tests shall be submitted to the granting type approval authority within ten working days from the execution of each test on a single vehicle. The test results shall be accompanied by a comprehensive test report at the end of the tests. The results shall be incorporated in the sample in chronological order of execution.
The granting type approval authority shall incorporate all valid emission test results to the relevant open statistical procedure until a ‘sample fail’ or a ‘sample pass’ outcome is reached in accordance with paragraph 5.10.5.
5.10.4.   Treatment of Outliers
The presence of outlying results in the sample statistical procedure may lead to a ‘fail’ outcome in accordance with the procedures described below:






(a)


Outliers shall be categorised as mild, intermediate or extreme.










(b)


An emissions test result shall be considered as a mild outlier if it is more than the applicable emission limit but less than 1,3 times the applicable emission limit. The presence of a mild outlier only counts in the number of failed results in paragraph 5.10.5 below.










(c)


An emissions test result shall be considered as an intermediate outlier if it is equal or greater than 1,3 times the applicable emission limit. The presence of two such outliers in a sample shall lead to a fail of the sample.










(d)


An emissions result shall be considered as an extreme outlier if it is equal or greater than 2,5 times the applicable emission limit. The presence of one such outlier in a sample shall lead to a fail of the sample. In such case, the plate number of the vehicle shall be communicated to the manufacturer and to the granting type approval authority. This possibility shall be communicated to the vehicle owners before testing.




5.10.5.   Pass/Fail decision for a sample
For the purposes of deciding on a pass/fail result for the sample, ‘p’ is the count of passed results, and ‘f’ is the count of failed results. Each passed test result shall increase the ‘p’ count by 1 and each failed test result shall increase the ‘f’ count by 1 for the relevant open statistical procedure.
Upon the incorporation of valid emission test results to an open instance of the statistical procedure, the type approval authority shall perform the following actions:






(a)


update the cumulative sample size ‘n’ for that instance to reflect the total number of valid emissions tests incorporated to the statistical procedure;










(b)


following an evaluation of the results, update the count of passed results ‘p’ and the count of failed results ‘f’;










(c)


compute the number of extreme and intermediate outliers in the sample in accordance with paragraph 5.10.4;










(d)


check whether a decision is reached with the procedure described below.




The decision depends on the cumulative sample size ‘n’, the passed and failed result counts ‘p’ and ‘f’, as well as the number of intermediate and/or extreme outliers in the sample. For the decision on a pass/fail of an ISC sample the granting type approval authority shall use the decision chart in Figure 4/2. The charts indicate the decision to be taken for a given cumulative sample size ‘n’ and failed count result ‘f’.
Two decisions are possible for a statistical procedure for a given combination of vehicle family, emissions test type and pollutant:

                  ‘Sample pass’ outcome shall be reached when the applicable decision chart from Figure 4/2 gives a ‘PASS’ outcome for the current cumulative sample size ‘n’ and the count of failed results ‘f’.

                  ‘Sample fail’ decision shall be reached, for a given cumulative sample size ‘n’, when at least one of the following conditions is fulfilled:






(a)


the applicable decision chart from Figure 4/2 gives a ‘FAIL’ decision for the current cumulative sample size ‘n’ and the count of failed results ‘f’;










(b)


there are two ‘FAIL’ decisions with intermediate outliers;










(c)


there is one ‘FAIL’ decision with an extreme outlier.




If no decision is reached, the statistical procedure shall remain open and further results shall be incorporated into it until a decision is reached or the procedure is closed in accordance with paragraph 5.10.1.

6.   Compliance Assessment








6.1.


Within 10 working days of the end of the ISC testing for the sample as referred to in paragraph 5.10.5, the granting type approval authority shall start detailed investigations with the manufacturer in order to decide whether the ISC family (or part of it) complies with the ISC rules and whether it requires remedial measures. For multistage or special purpose vehicles the granting type approval authority shall also perform detailed investigations when there are at least three faulty vehicles with the same fault or five flagged vehicles in the same ISC family, as set out in paragraph 5.10.6.












6.2.


The granting type approval authority shall ensure that sufficient resources are available to cover the costs for compliance assessment. Without prejudice to national law, those costs shall be recovered by fees that can be levied on the manufacturer by the granting type approval authority. Such fees shall cover all testing or auditing needed in order for an assessment on compliance to be reached.












6.3.


On the request of the manufacturer, the granting type approval authority may extend the investigations to vehicles in service of the same manufacturer belonging to other ISC families which are likely to be affected by the same defects.












6.4.


The detailed investigation shall take no more than 60 working days after the start of the investigation by the granting type approval authority. The granting type approval authority may conduct additional ISC tests designed to determine why vehicles have failed during the original ISC tests. The additional tests shall be conducted under similar conditions as the original ISC failed ISC tests.
Upon the request of the granting type approval authority, the manufacturer shall provide additional information, showing in particular the possible cause of the failures, which parts of the family might be affected, whether other families might be affected, or why the problem which caused the failure at the original ISC tests is not related to in-service conformity, if applicable. The manufacturer shall be given the opportunity to prove that the in-service conformity provisions have been complied with.












6.5.


Within the deadline set out in paragraph 6.4, the granting type approval authority shall take the decision on the compliance or the non-compliance. In case of non-compliance, the granting type approval authority shall define the remedial measures for the ISC family according to paragraph 7. It shall notify them to the manufacturer.




7.   Remedial Measures








7.1.


The manufacturer shall establish a plan of remedial measures and submit it to the granting type approval authority within 45 working days of the decision on the compliance or non-compliance referred to in paragraph 6.5. That period may be extended by up to an additional 30 working days where the manufacturer demonstrates to the granting type approval authority that further time is required to investigate the non-compliance.

(i)


a description of the impact of the proposed remedial measures on the emissions, fuel consumption, driveability, and safety of each vehicle emission type, covered by the plan of remedial measures, including supporting data and technical studies;










(j)


where the plan of remedial measures includes a recall, a description of the method for recording the repair shall be submitted to the granting type approval authority. If a label is used, an example of it shall also be submitted.




For the purposes of point (d), the manufacturer may not impose maintenance or use conditions which are not demonstrably related to the non-conformity and the remedial measures.












7.4.


The repair shall be done expediently, within a reasonable time after the vehicle is received by the manufacturer for repair. Within 15 working days of receiving the proposed plan of remedial measures, the granting type approval authority shall approve it or require a new plan in accordance with paragraph 7.5.












7.5.


When the granting type approval authority does not approve the plan of remedial measures, the manufacturer shall develop a new plan and submit it to the granting type approval authority within 20 working days of notification of the decision of the granting type approval authority.












7.6.


If the granting type approval authority does not approve the second plan submitted by the manufacturer, it shall take all appropriate measures to restore conformity, including withdrawal of type approval where necessary.












7.7.


The granting type approval authority shall notify its decision on remedial measures to the relevant Contracting Parties within 5 working days.












7.8.


The remedial measures shall apply to all vehicles in the ISC family (or other relevant families identified by the manufacturer in accordance with paragraph 6.2) that are likely to be affected by the same defect. The granting type approval authority shall decide if it is necessary to amend the type approval.












7.9.


The manufacturer is responsible for the execution of the approved plan of remedial measures in all relevant Contracting Parties and for keeping a record of every vehicle removed from the market or recalled and repaired and the workshop which performed the repair.












7.10.


The manufacturer shall keep a copy of the communication with the customers of affected vehicles related to the plan of remedial measures. The manufacturer shall also maintain a record of the recall campaign, including the total number of vehicles affected per Contracting Party and the total number of vehicles already recalled per Contracting Party, along with an explanation of any delays in the application of the remedial measures. The manufacturer shall provide that record of the recall campaign to the granting type approval authority, the type approval authorities of each Contracting Party every two months.












7.11.


Contracting Parties shall take measures to ensure that the approved plan of remedial measures is applied within two years to at least 90 % of affected vehicles registered in their territory.












7.12.


The repair and modification or addition of new equipment shall be recorded in a certificate provided to the vehicle owner, which shall include the number of the remedial campaign.




8.   Annual report by the granting type approval authority
The granting type approval authority shall make available on a publicly accessible website, free of charge and without the need for the user to reveal their identity or sign up, a report with the results of all the finalised ISC investigations of the previous year, at the latest by 31 March of each year.

Components for adjusting the idling speed












2.5.1.


Definition
For the purposes of this Regulation, ‘
               components for adjusting the idling speed
               ’ means controls for changing the idling conditions of the engine which may be easily operated by a mechanic using only the tools described in paragraph 2.5.1.1 of this annex. In particular, devices for calibrating fuel and air flows are not considered as adjustment components if their setting requires the removal of the set-stops, an operation which cannot normally be performed except by a professional mechanic.












2.5.1.1.


Tools which may be used to control components for adjusting the idling speed: screwdrivers (ordinary or cross-headed), spanners (ring, open-end or adjustable), pliers, Allen keys.












2.5.2.


Determination of measurement points












2.5.2.1.


A measurement at the setting in accordance with the conditions fixed by the manufacturer is performed first.












2.5.2.2.


For each adjustment component with a continuous variation, a sufficient number of characteristic positions shall be determined.












2.5.2.3.


The measurement of the carbon-monoxide content of exhaust gases shall be carried out for all the possible positions of the adjustment components, but for components with a continuous variation only the positions defined in paragraph 2.5.2.2 of this annex shall be adopted.












2.5.2.4.


The Type 2 test shall be considered satisfactory if one or both of the two following conditions is met:












2.5.2.4.1.


None of the values measured in accordance with paragraph 2.5.2.3 of this annex exceed the limit values set out in paragraph 5.3.2.2 of this Regulation;












2.5.2.4.2.


The maximum content obtained by continuously varying one of the adjustment components while the other components are kept stable does not exceed the limit value, this condition being met for the various combinations of adjustment components other than the one which was varied continuously.












2.5.2.5.


The possible positions of the adjustment components shall be limited:












2.5.2.5.1.


On the one hand, by the larger of the following two values: the lowest idling speed which the engine can reach; the speed recommended by the manufacturer, minus 100 revolutions per minute;












2.5.2.5.2.


On the other hand, by the smallest of the following three values: the highest speed the engine can attain by activation of the idling speed components; the speed recommended by the manufacturer, plus 250 revolutions per minute; the cut-in speed of automatic clutches.












2.5.2.6.


In addition, settings incompatible with correct running of the engine shall not be adopted as measurement settings. In particular, when the engine is equipped with several carburettors all the carburettors shall have the same setting.












2.6.


Additional requirements for Hybrid Electric Vehicles
The vehicles shall be tested with the fuel consuming engine running. The manufacturer shall provide a ‘service mode’ that makes execution of this test possible.
If necessary, the special procedure provided for in paragraph 5.1.6 to this Regulation shall be used.

The sampling probe shall be inserted into the exhaust pipe to a depth of at least 300 mm or into the pipe connecting the exhaust with the sampling bag and as close as possible to the exhaust.












3.2.


The concentration in C\O (CCO) and CO2 (CCO2) shall be determined from the measuring instrument readings or recordings, by use of appropriate calibration curves.












3.3.


The corrected concentration for carbon monoxide regarding four-stroke engines is:



 (per cent vol.)












3.4.


The concentration in CCO (see paragraph 3.2 of this annex) measured according to the formulae contained in paragraph 3.3 of this annex need not be corrected if the total of the concentrations measured (CCO + CCO2) is for four-stroke engines at least:






(a)


For petrol 15 per cent










(b)


For LPG 13,5 per cent










(c)


For NG/biomethane 11,5 per cent.

In case the interpolation method is used VL and VH shall be specified in accordance with point 4.2.1.1.2 of Annex B4 to UN Regulation No 154. The dynamometer shall be adjusted to simulate the operation of a vehicle on the road at -7°C. Such adjustment may be based on a determination of the road load force profile at -7°C. Alternatively, the driving resistance determined may be adjusted for a 10per cent decrease of the coast-down time. The Technical service may approve the use of other methods for determining the driving resistance.




4.   Vehicle preconditioning
4.1.   Summary








4.1.1.


To ensure reproducible emission tests, the test vehicles shall be conditioned in a uniform manner. The conditioning consists of a preparatory drive on a chassis dynamometer followed by a soak period before the emission test according to paragraph 4.3 of this annex.




4.2.   Preconditioning








4.2.1.


The fuel tank(s) shall be filled with the specified test fuel. If the existing fuel in the fuel tank(s) does not meet the specifications contained in paragraph 3.4.1 of this annex, the existing fuel shall be drained prior to the fuel fill. The test fuel shall be at a temperature less than or equal to 289 K (+16 °C). For the above operations the evaporative emission control system shall neither be abnormally purged nor abnormally loaded.












4.2.2.


The vehicle is moved to the test cell and placed on the chassis dynamometer.












4.2.3.


The preconditioning consists of one complete driving cycle, Parts One and Two, according to Tables A4a/1 and A4a/2 and Figure A4a/1 of Annex 4a to the 07 series of amendments to this Regulation. At the request of the manufacturer, vehicles with a positive ignition engine may be preconditioned with one Part One and two Part Two driving cycles.












4.2.4.


During the preconditioning the test cell temperature shall remain relatively constant and not be higher than 303 K (30 °C).












4.2.5.


The drive-wheel tyre pressure shall be set in accordance with the provisions of paragraph 6.2.3 of Annex 4a to the 07 series of amendments to this Regulation.












4.2.6.


Within ten minutes of completion of the preconditioning, the engine shall be switched off.












4.2.7.


If requested by the manufacturer and approved by the Technical service, additional preconditioning may in exceptional cases be allowed. The Technical service may also choose to conduct additional preconditioning. The additional preconditioning consists of one or more driving schedules of the Part One cycle as described in Table A4a/1 and Figure A4a/1 of Annex 4a to the 07 series of amendments to this Regulation. The extent of such additional preconditioning shall be recorded in the test report.




4.3.   Soak methods








4.3.1.


One of the following two methods, to be selected by the manufacturer, shall be utilised to stabilise the vehicle before the emission test.












4.3.2.


Standard method
The vehicle is stored for not less than 12 hours nor for more than 36 hours prior to the low ambient temperature exhaust emission test. The ambient temperature (dry bulb) during this period shall be maintained at an average temperature of:
266 K (-7 °C) ± 3 K during each hour of this period and shall not be less than 260 K (-13 °C) nor more than 272 K (-1 °C). In addition, the temperature may not fall below 263 K (-10 °C) nor more than 269 K (-4 °C) for more than three consecutive minutes.












4.3.3.


Forced method
The vehicle shall be stored for not more than 36 hours prior to the low ambient temperature exhaust emission test.












4.3.3.1.


The vehicle shall not be stored at ambient temperatures which exceed 303 K (30 °C) during this period.












4.3.3.2.


Vehicle cooling may be accomplished by force-cooling the vehicle to the test temperature. If cooling is augmented by fans, the fans shall be placed in a vertical position so that the maximum cooling of the drive train and engine is achieved and not primarily the sump. Fans shall not be placed under the vehicle.












4.3.3.3.


The ambient temperature need only be stringently controlled after the vehicle has been cooled to 266 K (-7 °C) ± 2 K, as determined by a representative bulk oil temperature.
A representative bulk oil temperature is the temperature of the oil measured near the middle of the oil sump, not at the surface or at the bottom of the oil sump. If two or more diverse locations in the oil are monitored, they shall all meet the temperature requirements.












4.3.3.4.


The vehicle shall be stored for at least one hour after is has been cooled to 266 K (-7 °C) ± 2 K, prior to the low ambient temperature exhaust emission test. The ambient temperature (dry bulb) during this period shall average 266 K (-7 °C) ± 3 K, and shall not be less than 260 K (-13 °C) or more than 272 K (-1 °C).
In addition, the temperature may not fall below 263 K (-10 °C) or exceed 269 K (-4 °C), for more than three consecutive minutes.












4.3.4.


If the vehicle is stabilised at 266 K (-7 °C), in a separate area and is moved through a warm area to the test cell, the vehicle shall be restabilised in the test cell for at least six times the period the vehicle is exposed to warmer temperatures. The ambient temperature (dry bulb) during this period shall average 266 K (-7 °C) ± 3 K and shall not be less than 260 K (-13 °C) nor more than 272 K (-1 °C).
In addition, the temperature may not fall below 263 K (-10 °C) or exceed 269 K (-4 °C), for more than three consecutive minutes.




5.   Dynamometer procedure
5.1.   Summary








5.1.1.


The emission sampling is performed over a test procedure consisting of the Part One cycle (Annex 4a to the 07 series of amendments to this Regulation, Table A4a/1 and Figure A4a/1). Engine start-up, immediate sampling, operation over the Part One cycle and engine shut-down make a complete low ambient temperature test, with a total test time of 780 seconds. The exhaust emissions are diluted with ambient air and a continuously proportional sample is collected for analysis. The exhaust gases collected in the bag are analysed for hydrocarbons, carbon monoxide, and carbon dioxide. A parallel sample of the dilution air is similarly analysed for carbon monoxide, total hydrocarbons and carbon dioxide.




5.2.   Dynamometer operation








5.2.1.


Cooling fan












5.2.1.1.


A cooling fan is positioned so that cooling air is appropriately directed to the radiator (water cooling) or to the air intake (air-cooling) and to the vehicle.












5.2.1.2.


For front-engined vehicles, the fan shall be positioned in front of the vehicle, within 300 mm of it. In the case of rear-engined vehicles or if the above arrangement is impractical, the cooling fan shall be positioned so that sufficient air is supplied to cool the vehicle.












5.2.1.3.


The fan speed shall be such that, within the operating range of 10 km/h to at least 50 km/h, the linear velocity of the air at the blower outlet is within ± 5 km/h of the corresponding roller speed. The final selection of the blower shall have the following characteristics:






(a)


Area: at least 0,2 m2;










(b)


Height of the lower edge above ground: approximately 20 cm.




As an alternative the blower linear air speed shall be at least 6 m/s (21,6 km/h). At the request of the manufacturer, for special vehicles (e.g. vans, off-road) the height of the cooling fan may be modified.












5.2.1.4.


The vehicle speed as measured from the dynamometer roll(s) shall be used (paragraph 1.2.6 of Appendix 1 to Annex 4a to the 07 series of amendments to this Regulation).












5.2.2.


Reserved












5.2.3.


Preliminary testing cycles may be carried out if necessary, to determine how best to actuate the accelerator and brake controls so as to achieve a cycle approximating to the theoretical cycle within the prescribed limits, or to permit sampling system adjustment. Such driving shall be carried out before ‘START’ according to Figure A8/1.












5.2.4.


Humidity in the air shall be kept low enough to prevent condensation on the dynamometer roll(s).












5.2.5.


The dynamometer shall be thoroughly warmed as recommended by the dynamometer manufacturer, and using procedures or control methods that assure stability of the residual frictional power.












5.2.6.


The time between dynamometer warming and the start of the emission test shall be no longer than 10 minutes if the dynamometer bearings are not independently heated. If the dynamometer bearings are independently heated, the emission test shall begin no longer than 20 minutes after dynamometer warming.












5.2.7.


If the dynamometer power is to be adjusted manually, it shall be set within one hour prior to the exhaust emission test phase. The test vehicle may not be used to make the adjustment. The dynamometer, using automatic control of pre-selectable power settings, may be set at any time prior to the beginning of the emission test.












5.2.8.


Before the emission test driving schedule may begin, the test cell temperature shall be 266 K (-7 °C) ± 2 K, as measured in the air stream of the cooling fan with a maximum distance of 1.5 m from the vehicle.












5.2.9.


During operation of the vehicle the heating and defrosting devices shall be shut off.












5.2.10.


The total driving distance or roller revolutions measured are recorded.












5.2.11.


A four-wheel drive vehicle shall be tested in a two-wheel drive mode of operation. The determination of the total road force for dynamometer setting is performed while operating the vehicle in its primary designed driving mode. At the request of the manufacturer a four-wheel drive vehicle shall be tested in its primary drive mode of operation.




5.3.   Performing the test








5.3.1.


The provisions of paragraph 6.4, excluding 6.4.1.2, of Annex 4a to the 07 series of amendments to this Regulation apply in respect of starting the engine, carrying out the test and taking the emission samples. The sampling begins before or at the initiation of the engine start-up procedure and ends on conclusion of the final idling period of the last elementary cycle of the Part One (urban driving cycle), after 780 seconds.
The first driving cycle starts with a period of 11 seconds idling as soon as the engine has started.












5.3.2.


For the analysis of the sampled emissions the provisions of paragraph 6.5, excluding paragraph 6.5.2, of Annex 4a to the 07 series of amendments to this Regulation apply. In performing the exhaust sample analysis, the Technical service shall exercise care to prevent condensation of water vapour in the exhaust gas sampling bags.












5.3.3.


For the calculations of the mass emissions the provisions of paragraph 6.6 of Annex 4a to the 07 series of amendments to this Regulation apply.




5.4.   Additional requirements for Hybrid Electric Vehicles








5.4.1.


For OVC vehicles, the measurements of emissions of pollutants shall be carried out under the same conditions as specified for condition B of the NEDC based Type I test (paragraphs 3.1.3 and 3.2.3 of Annex 14 to the 07 series of amendments to this Regulation).












5.4.2.


For NOVC vehicles, the measurements of emissions of pollutants shall be carried out under the same conditions as in the NEDC based Type I test as set out in Annex 4a to the 07 series of amendments to this Regulation.




6.   Other requirements
6.1.   Irrational emission control strategy








6.1.1.


Any irrational emission control strategy which results in a reduction in effectiveness of the emission control system under normal operating conditions at low temperature driving, so far as not covered by the standardised emission tests, may be considered a defeat device.

(1)  The values quoted in the specifications are ‘true values’. In establishment of their limit values the terms of ISO 4259 Petroleum products – Determination and application of precision data in relation to methods of test have been applied and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account; in fixing a maximum and minimum value, the minimum difference is 4R (R = reproducibility). Notwithstanding this measure, which is necessary for technical reasons, the manufacturer of fuels shall nevertheless aim at a zero value where the stipulated maximum value is 2R and at the mean value in the case of quotations of maximum and minimum limits. Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.

(2)  A correction factor of 0,2 for MON and RON shall be subtracted for the calculation of the final result in accordance with EN 228:2008.

(3)  The fuel may contain oxidation inhibitors and metal deactivators normally used to stabilise refinery gasoline streams, but detergent/dispersive additives and solvent oils shall not be added.

(4)  Ethanol is the only oxygenate that shall be intentionally added to the reference fuel. The Ethanol used shall conform to EN 15376.

(5)  The actual sulphur content of the fuel used for the Type 6 test shall be reported.

(6)  There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.

(7)  The values referred to in the specifications are ‘true values’. When establishing the value limits, the terms of ISO 4259 Petroleum products – Determination and application of precision data in relation to methods of test were applied. When fixing a minimum value, a minimum difference of 2R above zero was taken into account. When fixing a maximum and minimum value, the minimum difference used was 4R (R = reproducibility). Notwithstanding this procedure, which is necessary for technical reasons, fuel manufacturers shall aim for a zero value where the stipulated maximum value is 2R and for the mean value for quotations of maximum and minimum limits. Where it is necessary to clarify whether fuel meets the requirements of the specifications, the ISO 4259 terms shall be applied.

(8)  In cases of dispute, the procedures for resolving the dispute and interpretation of the results based on test method precision, described in EN ISO 4259 shall be used.

(9)  In cases of national dispute concerning sulphur content, either EN ISO 20846 or EN ISO 20884 shall be called up similar to the reference in the national annex of EN 228.

(10)  The actual sulphur content of the fuel used for the Type 6 test shall be reported.

(11)  The unleaded petrol content may be determined as 100 minus the sum of the percentage content of water and alcohols.

(12)  There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.

(13)  Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.
