Commission Regulation (EU) 2017/1151 of 1 June 2017 supplementing Regulation (EC) No 715/2007 of the European Parliament and of the Council on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and of the Council, Commission Regulation (EC) No 692/2008 and Commission Regulation (EU) No 1230/2012 and repealing Commission Regulation (EC) No 692/2008 (Text with EEA relevance)

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 point 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.

The functions described above shall be executed directly in the Electronic Platform once the relevant functions are available.

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, and to the electronic platform when available, 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 Table 2 of Annex I of Regulation (EC) No 715/2007 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 point 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 point 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 point 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:

Outliers shall be categorised as mild, intermediate or extreme.

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 point 5.10.5. below.

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.

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:

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

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

• — compute the number of extreme and intermediate outliers in the sample in accordance with point 5.10.4.;

• — 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 2 for vehicles based on types approved as of 1 January 2020 and the decision chart in Figure 2.a for vehicles based on types approved until 31 December 2019. 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 2 or Figure 2.a 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:

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

• — there are two ‘FAIL’ decisions with intermediate outliers;

• — 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 point 5.10.1.

5.10.6.   ISC for completed vehicles and multistage special purpose vehicles

The manufacturer of the base vehicle shall determine the allowed values for the parameters listed in Table 3. The allowed Parameter Values for each family shall be recorded in the information document of the emissions type approval (see Appendix 3 to Annex I) and in the Transparency list 1 of Appendix 5. The final-stage manufacturer shall only be allowed to use the base vehicle emission values if the completed vehicle remains within the allowed Parameter Values. The parameter values for each final vehicle shall be recorded in its Certificate of Conformity.

Table 3

Allowed Parameter Values for multistage and multistage special purpose vehicles to use the base vehicle emission type approval

Parameter Values	Allowed values from - to
Final Vehicle actual mass (in kg)
Final Vehicle technically permissible maximum laden mass (in kg)
Frontal area for final vehicle (in cm2)
Rolling resistance (kg/t)
Projected frontal area of air entrance of the front grille (in cm2)

If a completed or multistage special purpose vehicle is tested and the result of the test is below the applicable emission limit, the vehicle shall be considered as a pass for the ISC family for the purposes of point 5.10.3.

If the result of the test on a completed or multistage special purpose vehicle exceeds the applicable emission limits but is not higher than 1,3 times the applicable emission limits, the tester shall examine whether that vehicle complies with the values in Table 3. Any non-compliance with these values shall be reported to the granting type approval authority. If the vehicle does not comply with those values, the granting type approval authority shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or multistage special purpose vehicle to restore conformity, including the withdrawal of the type-approval. If the vehicle complies with the values in Table 3, it shall be considered as a flagged vehicle for the in-service conformity family for the purposes of point 6.1.

If the result of the test exceeds 1,3 times the applicable emission limits, shall be considered as a fail for the in-service conformity family for the purposes of point 6.1., but not as an outlier for the relevant ISC family. If the completed or multistage special purpose vehicle does not comply with the values in Table 3, this shall be reported to the granting type approval authority, who shall investigate the reasons for the non-compliance and take the appropriate measures regarding the manufacturer of the completed or multistage special purpose vehicle to restore conformity, including the withdrawal of the type-approval.

6. COMPLIANCE ASSESSMENT

• 6.1.Within 10 working days of the end of the ISC testing for the sample as referred to in point 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 point 5.10.6.

These Declared Maximum RDE values shall be used for checking the compliance of cars when applicable, including for tests performed during In-service Conformity and Market Surveillance.

The RDE performance shall be demonstrated by performing the necessary tests in the PEMS test family on the road operated over their normal driving patterns, conditions and payloads. The necessary tests shall be representative for vehicles operated on their real driving routes, with their normal load. The requirements of emission limits shall be fulfilled for the urban operation and the complete PEMS trip.

The RDE tests required by this Annex provide a presumption of conformity. The presumed conformity may be reassessed by additional RDE tests. Verification of compliance shall be made in accordance with the rules of in-service conformity.
