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 B.1  
Illustration of the in -service conformity process (where 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, EC to the Commission, and third parties that meet the 
requirements laid down in Implementing Re gulation (EC) 2022/ 163) 
 
3. ISC family definition  
An ISC family shall be composed of the following vehicles:  
 (a) For tailpipe emissions (Type 1 , Type 1a and  Type 6 tests), the vehicles covered 
by the PEMS test family, as described in Appendix 7 of Annex I IIA, 
 
 
EN 2  EN  (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 authorit y 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 obser ved 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 warr anty 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 Article 9(3). The ISC repor ts 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 c onformity 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, the y may randomly choose ISC families to test.  
5. ISC testing  
The manufacturer shall perform ISC testing for tailpipe emissions compr ising at least the 
Type 1 test for all ISC families.  The manufacturer may also perform Type 1a, 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 testin g using the Electronic Platform for in -
service conformity described in point 5.9, or other appropriate means where this is not 
possible.  
The granting type approval authority shall check an appropriate number of ISC families each 
year, as set out in point 5 .4. The granting type approval authority shall include all results of 
the ISC testing in the Electronic Platform for in -service conformity described in point 5.9.  
Other actors  may perform checks on any number of ISC families each year. The y shall report 
to the granting type approval authority all results of the ISC testing using the Electronic 
Platform for in -service conformity described in point 5.9 , or other appropriate means where 
this is not possible . 
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 third parties.  The audit shall be based on the information provided by the manufacturers, or 
third parties which shall include at least the detailed ISC report in accordance with  
EN 3  EN Appendix  3. The granting type approval authority may require the manufacturers, or third 
parties 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 t he 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 point 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 test s 
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 Annex XXI.  
ISC testing with the Type 1a test  shall be performed in accordance with Annex IIIA, 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 VIII.  
5.4. Frequency and scope of ISC testing  
The time period between commencing two in -service conformity checks by th e 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 point 4.  
Each granting type approval authorities shall perform both the Type 1 and Type 1a  tests on a 
minimum of 5  % of the ISC families pe r manufacturer per year or at least two ISC families 
per manufacturer per year, where available. The requirement for testing a minimum of 5  % 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 according to Article 9, paragraph 3. 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  % of the in -service conformity 
families per manufacturer per year or at least two ISC families per manufacturer per year.   
EN 4  EN 5.6. Testing plan  
When performing testing for ISC, the granting type appr oval authority shall draft a testing 
plan. In the case of Type 1a testing, that plan shall include testing to check ISC compliance 
under a wide range of conditions in accordance with Annex IIIA.  
5.7. Selection of vehicles for ISC testing  
The information ga thered 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, Type 1a , 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 requiremen ts 
The vehicle shall belong to an ISC family as described in point 3 and shall comply with the 
checks set out in the table in Appendix 1. It shall be registered in the Union and have been 
driven in the Union for at least 90  % of its driving time. The emiss ions 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 -EU c ountry may be tested, if they belong to the same 
ISC family and are accompanied by a certificate of conformity . 
The vehicles selected shall be accompanied by a maintenance record which shows that the 
vehicle has been properly maintained and has been servic ed 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 conditio ns 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 laid down in Directive 98/70/EC of the European Parliament and of 
the Council1 or if there is evidence or record of fuelling with the wrong type of fuel.  
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.  
                                                 
1 Directive 98/70/EC of the European Parliament and of the Council of 13  October 1998 relating to the 
quality of petrol and diesel fuels and amending Council Directive 93/12/EEC (OJ  L 350, p.  58).  
EN 5  EN The following checks shall be carried out: OBD checks (performed before or after the test), 
visual check s 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, fu el 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 an d replaced with hot 
water.  
A fuel sample shall be collected and kept in accordance with the requirements of Annex IIIA 
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 point 
6.1. 
5.8. Sample size  
When manufacturers apply the statistical proced ure set out in point 5.10 for the Type 1 test, 
the number of sample lots shall be set on the basis of the annual sales volume of an in -service 
family in the Union, as described in the following table:  
Table B.1  
Number of sample lots for ISC testing with T ype 1 tests  
EU Registrations per calendar year of vehicles in 
the sampling period  Number of sample lots  
(for Type 1 tests)  
up to 100000  1 
100001 to 200000  2 
above 200000  3 
 
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 Europe for the previous year are covered. In case 
the same PEMS family is shared between more brands, then all brand s 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  vehicle s used in different ambient and/or typical use conditions  from 
those selected for the first sample.  
5.9. Use of the Electronic Platform for in -service conformity and access to data required 
for testing  
The Commission shall set up an electronic platform in order to facilitate the exchange of data 
between on the one side, the manufacturers , other actors and on the other side the granting 
type approval authority and the taking of the decision on the sample fail or pass.  
The manufacturer shall complete the package on Testing Transparency referred to in Article 5 
(12) in the format specified in Tables 1 and 2 of Ap pendix 5 and in the Table in this point and  
EN 6  EN transmit it to the type -approval authority which grants the emission type -approval. 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 the Table 1 provide sufficient information for vehicles to be tested.  
Once the electronic platform referred to in the first paragraph becomes available, the type -
approval authority which grants the emission type -approval shall upload the information in 
Tables 1 and 2 of Appendix 5 to this platform within 5 working days of receiving it.  
All information in Tables 1 and 2 of Appendix 5 shall be accessible to the public in an 
electronic form free of charge.  
The following information shall also be part of the pa ckage on Testing Transparency and shall 
be provided by the manufacturer free -of-charge within 5 working days of the request by other 
actors .

description of current and voltage access points 
and list of devices used for current and voltage 
measurement during type approval.   
 
 
5.10.  Statistical Procedure  
5.10.1.  General  
The verification of in -service conformi ty 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 a nd RDE tests.   
EN 7  EN 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 c ases 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 point 6.1.  
Test results shall not be multiplied by deterioration factors.  
For vehicles that have a Declared Maximum RDE Values reported in point 48.2 of the 
Certificate of Conformity, as described in Annex VIII of Regulation 2020/683 /EC which is 
lower than the emission limits set out in Annex I to Regulation (EC) No 715/2007, th e 
conformity shall be checked against the se Declared Maximum RDE Value s. If the sample is 
found not to conform with the Declared Maximum RDE Values, the granting type approval 
authority shall require the manufacturer to take corrective actions.  
Prior to th e 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 proce dures 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 ve hicle 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 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 d irectly 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 wri tten consent from all the interested 
parties providing test results to a pool of results, and a notification to the type approval 
authorit ies, and to the electronic platform when available,  prior to the start of testing. One of 
the parties shall be designa ted 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 pollutant s when the 
emissions result is equal or below the emission limit set out in Annex I of Regulation (EC) No 
715/2007 for that type of test.   
EN 8  EN 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 chronologi cal 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 resu lt 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 manufact urer 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 pa ssed 
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 emiss ion 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 point 5.10.4.  ; 
(d) check whether a decision is reached with the procedure described below.   
EN 9  EN 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 B.2 for vehicles based on types approved as of 1  January 2020 and 
the decision chart in Figure B.2.a for vehicles based on types approved u ntil 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 an d pollutant:  
‘Sample pass’ outcome shall be reached when the applicable decision chart from Figure B.2 
or Figure B.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:  
(a) the applicable decision chart from Figure B.2 or Figure B.2.a gives a ‘FAIL’ decision for 
the current cumulative sample size ‘n’ and the count of fai led 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 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 B.3. The allowed Parameter Values for each family shall be recorded in the 
information document of the emissions type appro val (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 va lues for each final vehicle shall be recorded in its 
Certificate of Conformity.  
Table B.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:  
EN 11  EN 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 B.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 regar ding 
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 B.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 B.3, this shall be reported to the granting type approval 
authority, who shall investigate the reasons for the non -compliance and tak e 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 days of the end of the ISC testing fo r 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 remedi al 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 se t out in point 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.   
EN 12  EN 6.3. On the request of the manufacturer, the granting type approval authority may ext end 
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 inves tigation 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 cond itions as the 
original ISC failed 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
