4. CONFORMITY OF PRODUCTION  
4.1. Introduction  
4.1.1. Every vehicle produced under a Type Approval according to this Regu ­
lation shall be so manufactured as to conform to the type approval 
requirements of this Regulation. The Manufacturer shall implement 
adequate arrangements and documented control plans and carry-out at 
specified intervals as given in this regulation the necessary emission and 
OBD tests to verify continued conformity with the approved type. The 
approval authority shall verify and agree with these arrangements and 
control plans of the manufacturer and perform audits and conduct 
emission and OBD tests at specific intervals, as given in this regulation, 
at the premises of the manufacturer, including production and test 
facilities as part of the product conformity and continued verification 
arrangements as described in Annex X of Directive 2007/46/EC.  
4.1.2. The manufacturer shall check the conformity of production by testing 
the emissions of pollutants (given in Table 2 of Annex I to Regulation 
(EC) No 715/2007), the emission of CO  2 (along with the measurement 
of electric energy consumption, EC), the crankcase emissions, evap ­
orative emissions and the OBD. The verification shall therefore 
include the tests of types 1, 3, 4 and the test for OBD, as described 
in section 2.4 of this Annex and the relevant annexes quoted therein. 
The specific procedures for conformity of production are set out in 
Sections 4.2 to 4.7 and Appendixes 1 and 2.  
4.1.3. For the purposes of the manufactures conformity of production check, 
the family means the CO  2 interpolation family for tests of Type 1 and 3, 
includes for the Type 4 test the extensions described in paragraph 3.2 of 
this Annex and the OBD family with the extensions described in 
paragraph 3.3 of this Annex for the OBD tests.  
4.1.4. The frequency for product verification performed by the manufacturer 
shall be based on a risk assessment methodology consistent with the 
international standard ISO 31000:2009 — Risk Management — Prin ­
ciples and guidelines and at least for Type 1 with a minimum frequency 
of one verification per 5 000 vehicles produced per family or once per 
year, whichever comes first.  
4.1.5. The Approval Authority which has granted type-approval may at any 
time verify the conformity control methods applied in each production 
facility.  
For the purpose of this regulation the Approval Authority shall perform 
audits for verifying the manufacturers arrangements and documented 
control plans at the premises of the manufacturer on a risk assessment 
methodology consistent with the international standard ISO 31000:2009 
— Risk Management — Principles and guidelines and, in all cases, 
with a minimum frequency of one audit per year.  
If the Approval Authority is not satisfied with the auditing procedure of 
the manufacturer, physical test shall directly be carried out on 
production vehicles as described in Sections 4.2 to 4.9.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 34  
4.1.6. The normal frequency of physical test verifications by the Approval 
Authority shall be based on the results of the auditing procedure of 
the manufacturer on a risk assessment methodology and in all cases 
with a minimum frequency of one verification test per three years. The 
Approval Authority shall conduct these physical emission tests and 
OBD tests on production vehicles as described in Sections 4.2 to 4.9.  
In the case of the manufacturer running the physical tests, the Approval 
Authority shall witness the tests at the manufacturer's facility.  
4.1.7. The Approval Authority shall report the results of all audit checks and 
physical tests performed on verifying conformity of the manufacturers 
and file it for a period of minimum 10 years. These reports should be 
available for other type approval authorities and the European 
Commission on request.  
4.1.8. In case of non-conformity Article 30 of Directive 2007/46/EC shall 
apply.  
4.2. Checking the conformity of the vehicle for a type 1 test  
4.2.1. The Type 1 test shall be carried out on production vehicles of a valid 
member of the CO  2 interpolation family as described in the TA 
certificate. The limit values against which to check conformity for 
pollutants are set out in Table 2 of Annex I to Regulation (EC) 
No 715/2007. As regards CO  2 emissions, the limit value shall be the 
value determined by the manufacturer for the selected vehicle in 
accordance with the interpolation methodology set out in Sub-Annex 
7 of Annex XXI. The interpolation calculation shall be verified by the 
approval authority.  
4.2.2. A sample of three vehicles shall be selected at random in the family. 
After selection by the approval authority, the manufacturer shall not 
undertake any adjustment to the vehicles selected.  
4.2.2.1. The selection shall only include finalised production vehicles which 
have completed a maximum of 80 km and those vehicles will be 
referred to as zero km vehicles for the purposes of checking conformity 
against Type 1 test. The vehicle shall be tested on the appropriate 
WLTP cycle as described in Annex XXI to this Regulation notwith ­
standing the requirements for test repetitions, or km of vehicles. The 
test results shall be the values after all corrections according to this 
regulation are applied.  
4.2.3. The statistical method for calculating the test criteria is described in 
Appendix 1.  
The production of a family shall be deemed to not conform when a fail 
decision is reached for one or more of the pollutants and CO  2 values, 
according to the test criteria in Appendix 1.  
The production of a family shall be deemed to conform once a pass 
decision is reached for all the pollutants and CO  2 values according to 
the test criteria in Appendix 1.  
When a pass decision has been reached for one pollutant, that decision 
shall not be changed by any additional tests carried out to reach a 
decision for the other pollutants and CO  2 values.  
If a pass decision is not reached for all the pollutants and CO  2 values, a 
test shall be carried out on another vehicle, up to the maximum of 16 
vehicles, and the procedure described in Appendix 1 for taking a pass 
or fail decision shall be repeated (see Figure I.4.2).  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 35  
Figure I.4.2
  
4.2.4. At the request of the manufacturer and with the acceptance of the 
approval authority, tests may be carried out on a vehicle of the 
family with a maximum of 15 000 km in order to establish measured 
evolution coefficients EvC for pollutants/CO  2 for each family. The 
running-in procedure shall be conducted by the manufacturer, who 
shall not to make any adjustments to these vehicles.  
4.2.4.1. In order to establish a measured evolution coefficient with a run-in 
vehicle the procedure shall be as follows:  
(a) the pollutants/CO  2 shall be measured at a mileage of at most 80 km 
and at ‘x’ km of the first tested vehicle;  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 36  
(b) the evolution coefficient (EvC) of the pollutants/CO  2 between 
80 km and ‘x’ km shall be calculated as:  
EvC  meas ¼ values at ‘x’ km =values at 80 km  
(c) the other vehicles in the interpolation family shall not be run in, but 
their zero km emissions/EC/CO  2 shall be multiplied by the 
evolution coefficient of the first run-in vehicle. In this case, the 
values to be taken for testing as in Appendix 1 shall be:  
(i) the values at ‘x’ km for the first vehicle;  
(ii) the values at zero km multiplied by the relevant evolution 
coefficient for the other vehicles.  
4.2.4.2. All these tests shall be conducted with commercial fuel. However, at the 
manufacturer’s request, the reference fuels described in Annex IX may 
be used.  
4.2.4.3. When checking the conformity of production for CO  2 , as an alternative 
to the procedure mentioned in Section 4.2.4.1 the vehicle manufacturer 
may use a fixed evolution coefficient EvC of 0,98 and multiply all 
values of CO  2 measured at zero km by this factor.  
4.2.5 Tests for conformity of production of vehicles fuelled by LPG or 
NG/biomethane may be performed with a commercial fuel of which 
the C3/C4 ratio lies between those of the reference fuels in the case 
of LPG, or of one of the high or low caloric fuels in the case of 
NG/biomethane. In all cases a fuel analysis shall be presented to the 
approval authority.  
4.2.6. Vehicles fitted with eco-innovations

Appendix 1  
Verification of conformity of production for Type 1 test—statistical method  
1. This appendix describes the procedure to be used to verify the production 
conformity requirements for the Type 1 test for pollutants/CO  2 , including 
conformity requirements for PEVs and OVC-HEVs.  
2. Measurements of the pollutants specified in Table 2 of Annex I to Regulation 
(EC) No 715/2007 and the emission of CO  2 shall be carried out on a 
minimum number of 3 vehicles, and consecutively increase until a pass or 
fail decision is reached.  
From the number of  N tests:  x 1, x 2, … x  N, the average  X tests and the variance  
VAR are to be determined from all  N measurements:  
X tests ¼ ðx 1 þ x 2 þ x 3 þ … þ x N Þ=N 
and 
VAR ¼ ððx 1 Ä X tests Þ 2 þ ðx 2 Ä X tests Þ 2 þ … þ ðx N Ä X tests Þ 2 Þ=ðN Ä 1Þ 
3. For each number of tests, one of the three following decisions (see (i) to ((iii) 
below) can be reached for pollutants based on the limit value  L for each 
pollutant, the average of all  N tests:  X tests , the variance of the test results  
VAR and the number of tests  N: 
(i) Pass the family if  X tests< A Ü L Ä VAR =L 
(ii) Fail the family if  X tests> A Ü L Ä ððN Ä 3Þ=13Þ Ü VAR =L 
(iii) Take another measurement if:  
A Ü L Ä VAR =L Ï X tests< A Ü L Ä ððN Ä 3Þ=13Þ Ü VAR =L 
For the measurement of pollutants the factor A is set at 1,05 in order to take 
into account inaccuracies in the measurements.  
4. For CO  2 and EC the normalised values for CO  2 and EC shall be used:  
x i ¼ CO  2testÄi=CO  2declared : 
x i ¼ EC  testÄi=EC DC; COP 
In the case of CO  2 and EC the factor A is set at 1.01 and the value for L is set 
at 1. So in the case of CO  2 and EC the criteria are simplified to:  
(i) Pass the family if  X tests< A Ä VAR  
(ii) Fail the family if  X tests> A Ä ððN Ä 3Þ=13Þ Ü VAR  
(iii) Take another measurement if:  
A Ä VAR Ï X tests< A Ä ððN Ä 3Þ=13Þ Ü VAR  
The A values for pollutants, EC and CO  2 will be reviewed and may change 
according to the available evidence. For this reason the Type Approval Auth ­
orities will need to provide the Commission with all relevant data at least for 
the initial period of 5 years.  ▼B

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 Article 5(2) of Regulation 
(EC) No 715/2007;  
(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 of these software versions and 
instructions to the authority on how to read the checksums; 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;  
(d) detailed technical reasoning of any AES; including explanations on why any 
of the exception clauses from the defeat device prohibition in Article 5(2) of 
Regulation (EC) No 715/2007 apply, where applicable; including hardware 
element(s) that need to be protected by the AES, if applicable; and/or proof 
of sudden and irreparable engine damage that cannot be prevented by regular 
maintenance and would occur in the absence of the AES along with a risk 
assessment estimating the risk with the AES and without it; reasoned expla ­
nation on why there is a need to use an AES for starting the engine;  
(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 modu ­
lation 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 CO  2 emissions by using the 
AES, compared to the BES.  ▼M1

4.2. The manufacturer shall demonstrate to the approval authority that the 
chosen vehicle, driving patterns, conditions and payloads are represen ­
tative for the PEMS test family. The payload and altitude require ­
ments, as specified in points 5.1 and 5.2, shall be used  ex-ante  to 
determine whether the conditions are acceptable for RDE testing.  
4.3. The approval authority shall propose a test trip in urban, rural and 
motorway environments meeting the requirements of point 6. For the 
purpose of trip design, the urban, rural and motorway parts shall be 
selected based on a topographic map. The urban part of the trip 
should be driven on urban roads with a speed limit of 60 km/h or 
less. In case the urban part of the trip needs to be driven for a limited 
period of time on roads with speed limit higher than 60 km/h, the 
vehicle shall be driven with speeds up to 60 km/h.  
▼B 
4.4. If for a vehicle the collection of ECU data influences the vehicle's 
emissions or performance the entire PEMS test family to which the 
vehicle belongs as defined in Appendix 7 shall be considered as 
non-compliant. Such functionality shall be considered as a ‘defeat 
device’ as defined in Article 3(10) of Regulation (EC) 715/2007.  
▼M1 
4.5. In order to also assess emissions during trips in hot start, a certain 
number of vehicles per PEMS test family, specified in point 4.2.7 in 
Appendix 7, shall be tested without conditioning the vehicle as 
described in point 5.3, but with a warm engine.  
▼B 
5. BOUNDARY CONDITIONS  
5.1. Vehicle payload and test mass  
5.1.1. The vehicle's basic payload shall comprise the driver, a witness of the 
test (if applicable) and the test equipment, including the mounting and 
the power supply devices.  
5.1.2. For the purpose of testing some artificial payload may be added as 
long as the total mass of the basic and artificial payload does not 
exceed 90% of the sum of the ‘mass of the passengers’ and the ‘pay- 
mass’ defined in points 19 and 21 of Article 2 of Commission Regu ­
lation (EU) No 1230/2012 (*).  
___________  
(*) Commission Regulation (EU) No 1230/2012 of 12 December 
2012 implementing Regulation (EC) No 661/2009 of the 
European Parliament and of the Council with regard to 
type-approval requirements for masses and dimensions of 
motor vehicles and their trailers and amending Directive 
2007/46/EC of the European Parliament and of the Council 
(OJ L 353, 21.12.2012, p. 31).  
5.2. Ambient conditions  
▼M1 
5.2.1. The test shall be conducted under ambient conditions laid down in 
this section. The ambient conditions become ‘extended’ when at least 
one of the temperature and altitude conditions is extended. The 
correction factor for extended conditions for temperature and 
altitude shall only be applied once. If a part of the test or the entire 
test is performed outside of normal or extended conditions, the test 
shall be invalid.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 130  
5.2.2. Moderate altitude conditions: Altitude lower or equal to 700 meters 
above sea level.  
5.2.3. Extended altitude conditions: Altitude higher than 700 meters above 
sea level and lower or equal to 1300 meters above sea level.  
▼M1 
5.2.4. Moderate temperature conditions: Greater than or equal to 273,15 K 
(0 °C) and lower than or equal to 303,15 K (30 °C).

5.2.6. By way of derogation from the provisions of points 5.2.4 and 5.2.5 
the lower temperature for moderate conditions shall be greater or 
equal to 276,15 K (3 °C) and the lower temperature for extended 
conditions shall be greater or equal to 271,15 K (– 2 °C) between 
the start of the application of binding NTE emission limits as defined 
in section 2.1 and until five years and four months after the dates 
given in paragraphs 4 and 5 of Article 10, of Regulation (EC) 
No 715/2007.  
5.3. Vehicle conditioning for cold engine-start testing  
Before RDE testing, the vehicle shall be preconditioned in the 
following way:  
Driven for at least 30 min, parked with doors and bonnet closed and 
kept in engine-off status within moderate or extended altitude and 
temperatures in accordance with points 5.2.2 to 5.2.6 between 6 and 
56 hours. Exposure to extreme atmospheric conditions (heavy 
snowfall, storm, hail) and excessive amounts of dust should be 
avoided. Before the test start, the vehicle and equipment shall be 
checked for damages and the absence of warning signals, suggesting 
malfunctioning.  
▼B 
5.4. Dynamic conditions  
The dynamic conditions encompass the effect of road grade, head 
wind and driving dynamics (accelerations, decelerations) and 
auxiliary systems upon energy consumption and emissions of the 
test vehicle. The verification of the normality of dynamic conditions 
shall be done after the test is completed, using the recorded PEMS 
data. This verification shall be conducted in 2 steps:  
5.4.1. The overall excess or insufficiency of driving dynamics during the trip 
shall be checked using the methods described in Appendix 7a to this 
Annex.  
▼M1 
5.4.2. If the trip results are valid following the verifications in accordance with 
point 5.4.1, the methods for verifying the normality of the test conditions 
as laid down in Appendices 5, 6, 7a and 7b to this Annex shall be 
applied. For OVC-HEVs only, the validity of a trip and the normality 
of test conditions are verified in accordance with Appendix 7c, while 
Appendices 5 and 6 do not apply.  
▼B 
5.5. Vehicle condition and operation  
5.5.1. Auxiliary systems  
The air conditioning system or other auxiliary devices shall be 
operated in a way which corresponds to their possible use by a 
consumer at real driving on the road.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 131  
5.5.2. Vehicles equipped with periodically regenerating systems  
5.5.2.1. ‘Periodically regenerating systems’ shall be understood in accordance 
with the definition in point 3.8.1 of Annex XXI.  
5.5.2.2. All results will be corrected with the K  i factors or with the K  i offsets 
developed by the procedures in sub-annex 6 of Annex XXI for type- 
approval of a vehicle type with a periodically regenerating system,  
5.5.2.3. If the emissions do not fulfil the requirements of point 3.1.0, then the 
occurrence of regeneration shall be verified. The verification of a 
regeneration may be based on expert judgement through cross- 
correlation of several of the following signals, which may include 
exhaust temperature, PN, CO  2, O 2 measurements in combination 
with vehicle speed and acceleration.  
If periodic regeneration occurred during the test, the result without the 
application of either the K  i -factor of the K  i offset shall be checked 
against the requirements of point 3.1.0. If the resulting emissions do 
not fulfil the requirements, then the test shall be voided and repeated 
once at the request of the manufacturer. The manufacturer may ensure 
the completion of the regeneration. The second test is considered valid 
even if regeneration occurs during it.  
5.5.2.4. At the request of the manufacturer, even if the vehicle fulfils the 
requirements of point 3.1.0, the occurrence of regeneration may be 
verified as in point 5.5.2.3 above. If the presence of regeneration can 
be proved and with the agreement of the Type Approval, the final 
results will be shown without the application of either the K  i factor or 
the Ki offset.  
5.5.2.5. The manufacturer may ensure the completion of the regeneration and 
precondition the vehicle appropriately prior to the second test.  
5.5.2.6. If regeneration occurs during the second RDE test, pollutants emitted 
during the repeated test shall be included in the emissions evaluation.

 02017R1151 — EN — 27.07.2017 — 001.003 — 138  
3.4. Installation of PEMS  
▼M1 
3.4.1.  General:  
The installation of the PEMS shall follow the instructions of the PEMS 
manufacturer and the local health and safety regulations. The PEMS 
should be installed as to minimise during the test electromagnetic inter ­
ferences as well as exposure to shocks, vibration, dust and variability in 
temperature. The installation and operation of the PEMS shall be leak- 
tight and minimise heat loss. The installation and operation of PEMS 
shall not change the nature of the exhaust gas nor unduly increase the 
length of the tailpipe. To avoid the generation of particles, connectors 
shall be thermally stable at the exhaust gas temperatures expected during 
the test. It is recommended not to use elastomer connectors to connect the 
vehicle exhaust outlet and the connecting tube. Elastomer connectors, if 
used, shall have no contact with the exhaust gas to avoid artefacts at high 
engine load.  
3.4.2.  Permissible backpressure  
The installation and operation of the PEMS sampling probes shall not 
unduly increase the pressure at the exhaust outlet in a way that may 
influence the representativeness of the measurements. It is thus recom ­
mended that only one sampling probe is installed in the same plane. If 
technically feasible, any extension to facilitate the sampling or connection 
with the exhaust mass flow meter shall have an equivalent, or larger, 
cross sectional area than the exhaust pipe. If the sampling probes 
obstruct a significant area of the tailpipe cross-section, backpressure 
measurement may be requested by the Type Approval Authority.  
3.4.3.  Exhaust mass flow meter  
Whenever used, the exhaust mass flow meter shall be attached to the 
vehicle’s tailpipe(s) in accordance with the recommendations of the 
EFM manufacturer. The measurement range of the EFM shall match 
the range of the exhaust mass flow rate expected during the test. The 
installation of the EFM and any exhaust pipe adaptors or junctions shall 
not adversely affect the operation of the engine or exhaust after-treatment 
system. A minimum of four pipe diameters or 150 mm of straight tubing, 
whichever is larger, shall be placed at either side of the flow-sensing 
element. When testing a multi-cylinder engine with a branched exhaust 
manifold, it is recommended to position the exhaust mass flow meter 
downstream of where the manifolds combine and to increase the cross 
section of the piping such as to have an equivalent, or larger, cross 
sectional area from which to sample. If this is not feasible, exhaust 
flow measurements with several exhaust mass flow meters may be 
used, if approved by the Type Approval Authorities. The wide variety 
of exhaust pipe configurations, dimensions and exhaust mass flow rates 
may require compromises, guided by good engineering judgement, when 
selecting and installing the EFM(s). It is permissible to install an EFM 
with a diameter smaller than that of the exhaust outlet or the total cross- 
sectional area of multiple outlets, providing it improves measurement 
accuracy and does not adversely affect the operation or the exhaust 
after-treatment as specified in point 3.4.2. It is recommended to 
document the EFM set-up using photographs.  
▼B 
3.4.4.  Global Positioning System (GPS)  
The GPS antenna should be mounted, e.g. at the highest possible location, 
as to ensure good reception of the satellite signal. The mounted GPS 
antenna shall interfere as little as possible with the vehicle operation.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 139  
3.4.5.  Connection with the Engine Control Unit (ECU)  
If desired, relevant vehicle and engine parameters listed in Table 1 can be 
recorded by using a data logger connected with the ECU or the vehicle 
network through standards, such as ISO 15031-5 or SAE J1979, OBD-II, 
EOBD or WWH-OBD. If applicable, manufacturers shall disclose labels 
to allow the identification of required parameters.  
3.4.6.  Sensors and auxiliary equipment  
Vehicle speed sensors, temperature sensors, coolant thermocouples or any 
other measurement device not part of the vehicle shall be installed to 
measure the parameter under consideration in a representative, reliable 
and accurate manner without unduly interfering with the vehicle 
operation and the functioning of other analysers, flow-measuring instru ­
ments, sensors and signals. Sensors and auxiliary equipment shall be 
powered independently of the vehicle. It is permitted to power any 
safety-related illumination of fixtures and installations of PEMS 
components outside of the vehicle’s cabin by the vehicle’s battery.  
▼M1 
3.5. Emissions sampling  
Emissions sampling shall be representative and conducted at locations of 
well-mixed exhaust where the influence of ambient air downstream of the 
sampling point is minimal. If applicable, emissions shall be sampled 
downstream of the exhaust mass flow meter, respecting a distance of at 
least 150 mm to the flow sensing element. The sampling probes shall be 
fitted at least 200 mm or three times the inner diameter of the exhaust 
pipe, whichever is larger, upstream of the point at which the exhaust exits 
the PEMS sampling installation into the environment. If the PEMS feeds 
back a flow to the tail pipe, this shall occur downstream of the sampling 
probe in a manner that does not affect during engine operation the nature 
of the exhaust gas at the sampling point(s). If the length of the sampling 
line is changed, the system transport times shall be verified and if 
necessary corrected.  
If the engine is equipped with an exhaust after-treatment system, the 
exhaust sample shall be taken downstream of the exhaust after- 
treatment system. When testing a vehicle with a branched exhaust 
manifold, the inlet of the sampling probe shall be located sufficiently 
far downstream so as to ensure that the sample is representative of the 
average exhaust emissions of all cylinders. In multi-cylinder engines, 
having distinct groups of manifolds, such as in a ‘V’ engine configur ­
ation, the sampling probe shall be positioned downstream of where the 
manifolds combine. If this is technically not feasible, multi-point 
sampling at locations of well-mixed exhaust may be used, if approved 
by the Type Approval Authority. In this case, the number and location of 
sampling probes shall match as far as possible those of the exhaust mass 
flow meters. In case of unequal exhaust flows, proportional sampling or 
sampling with multiple analysers shall be considered.  
If particles are measured, the exhaust shall be sampled from the centre of 
the exhaust stream. If several probes are used for emissions sampling, the 
particle sampling probe should be placed upstream of the other sampling 
probes. The particle sampling probe should not interfere with the 
sampling of gaseous pollutants. The type and specifications of the 
probe and its mounting shall be documented in detail.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 140  
If hydrocarbons are measured, the sampling line shall be heated to 463 
± 10 K (190 ± 10 °C). For the measurement of other gaseous components 
with or without cooler, the sampling line shall be kept at a minimum 
of 333 K (60 °C) to avoid condensation and to ensure appropriate 
penetration efficiencies of the various gases. For low pressure sampling 
systems, the temperature can be lowered corresponding to the pressure 
decrease provided that the sampling system ensures a penetration effi ­
ciency of 95 % for all regulated gaseous pollutants. If particles are 
sampled and not diluted at the tailpipe, the sampling line from the raw 
exhaust sample point to the point of dilution or particle detector shall 
be heated to a minimum of 373 K (100 °C). The residence time of the 
sample in the particle sampling line shall be less than 3 s until reaching 
first dilution or the particle detector.  
All parts of the sampling system from the exhaust pipe up to the particle 
detector, which are in contact with raw or diluted exhaust gas, shall be 
designed to minimize deposition of particles. All parts shall be made from 
antistatic material to prevent electrostatic effects.  
▼B 
4. PRE-TEST PROCEDURES  
4.1. PEMS leak check  
After the installation of the PEMS is completed, a leak check shall be 
performed at least once for each PEMS-vehicle installation as prescribed 
by the PEMS manufacturer or as follows. The probe shall be disconnected 
from the exhaust system and the end plugged. The analyser pump shall be 
switched on. After an initial stabilization period all flow meters shall read 
approximately zero in the absence of a leak. Else, the sampling lines shall 
be checked and the fault be corrected.  
The leakage rate on the vacuum side shall not exceed 0.5 per cent of the 
in-use flow rate for the portion of the system being checked. The analyser 
flows and bypass flows may be used to estimate the in-use flow rate.  
Alternatively, the system may be evacuated to a pressure of at least 20 
kPa vacuum (80 kPa absolute). After an initial stabilization period the 
pressure increase  Δp (kPa/min) in the system shall not exceed: 
Δp ¼ p e 
V s Ü q vs Ü 0:005 
Alternatively, a concentration step change at the beginning of the 
sampling line shall be introduced by switching from zero to span gas 
while maintaining the same pressure conditions as under normal system 
operation. If for a correctly calibrated analyser after an adequate period of 
time the reading is ≤ 99 per cent compared to the introduced concen ­
tration, the leakage problem shall be corrected.  
▼M1 
4.2. Starting and stabilizing the PEMS  
The PEMS shall be switched on, warmed up and stabilized in accordance 
with the specifications of the PEMS manufacturer until key functional 
parameters, e.g., pressures, temperatures and flows have reached their 
operating set points before test start. To ensure correct functioning, the 
PEMS may be kept switched on or can be warmed up and stabilized 
during vehicle conditioning. The system shall be free of errors and 
critical warnings.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 141  
4.3. Preparing the sampling system  
The sampling system, consisting of the sampling probe and sampling 
lines shall be prepared for testing by following the instruction of the 
PEMS manufacturer. It shall be ensured that the sampling system is 
clean and free of moisture condensation.  
▼B 
4.4. Preparing the Exhaust mass Flow Meter (EFM)  
If used for measuring the exhaust mass flow, the EFM shall be purged 
and prepared for operation in accordance with the specifications of the 
EFM manufacturer. This procedure shall, if applicable, remove conden ­
sation and deposits from the lines and the associated measurement ports.  
4.5. Checking and calibrating the analysers for measuring gaseous 
emissions  
Zero and span calibration adjustments of the analysers shall be performed 
using calibration gases that meet the requirements of point 5 of Appendix 
2. The calibration gases shall be chosen to match the range of pollutant 
concentrations expected during the RDE test. To minimize analyser drift, 
one should conduct the zero and span calibration of analysers at an 
ambient temperature that resembles, as closely as possible, the 
temperature experienced by the test equipment during the trip.  
▼M1 
4.6. Checking the analyser for measuring particle emissions  
The zero level of the analyser shall be recorded by sampling HEPA 
filtered ambient air at an appropriate sampling point, usually at the 
inlet of the sampling line. The signal shall be recorded at a constant 
frequency of at least 1,0 Hz averaged over a period of 2 minutes; the 
final concentration shall be within the manufacturer’s specifications, but 
shall not exceed 5 000 particles per cubic-centimetre.  
▼B 
4.7. Determining vehicle speed  
Vehicle speed shall be determined by at least one of the following 
methods:  
(a) a GPS; if vehicle speed is determined by a GPS, the total trip distance 
shall be checked against the measurements of another method 
according to point 7 of Appendix 4.  
(b) a sensor (e.g., optical or micro-wave sensor); if vehicle speed is 
determined by a sensor, the speed measurements shall comply with 
the requirements of point 8 of Appendix 2, or alternatively, the total 
trip distance determined by the sensor shall be compared with a 
reference distance obtained from a digital road network or topo ­
graphic map. The total trip distance determined by the sensor shall 
deviate by no more than 4 % from the reference distance.  
(c) the ECU; if vehicle speed is determined by the ECU, the total trip 
distance shall be validated according to point 3 of Appendix 3 and 
the ECU speed signal adjusted, if necessary to fulfil the requirements 
of point 3.3 of Appendix 3. Alternatively, the total trip distance as 
determined by the ECU can be compared with a reference distance  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 142  
obtained from a digital road network or topographic map. The total 
trip distance determined by the ECU shall deviate by no more than 
4 % from the reference.  
4.8. Check of PEMS set up  
The correctness of connections with all sensors and, if applicable, the 
ECU shall be verified. If engine parameters are retrieved, it shall be 
ensured that the ECU reports values correctly (e.g., zero engine speed 
[rpm] while the combustion engine is in key-on-engine-off status).  
►M1 The PEMS shall function free of errors and critical warnings. ◄ 
5. EMISSIONS TEST  
▼M1 
5.1. Test start  
Sampling, measurement and recording of parameters shall begin prior to 
the ‘ignition on’ of the engine. To facilitate time alignment, it is recom ­
mended to record the parameters that are subject to time alignment either 
by a single data recording device or with a synchronised time stamp. 
Before and directly after ‘ignition on’, it shall be confirmed that all 
necessary parameters are recorded by the data logger.  
5.2. Test  
Sampling, measurement and recording of parameters shall continue 
throughout the on-road test of the vehicle. The engine may be stopped 
and started, but emissions sampling and parameter recording shall 
continue. Any warning signals, suggesting malfunctioning of the PEMS, 
shall be documented and verified. If any error signal(s) appear during the 
test, the test shall be voided. Parameter recording shall reach a data 
completeness of higher than 99 %. Measurement and data recording 
may be interrupted for less than 1 % of the total trip duration but for 
no more than a consecutive period of 30 s solely in the case of 
unintended signal loss or for the purpose of PEMS system maintenance. 
Interruptions may be recorded directly by the PEMS but it is not 
permissible to introduce interruptions in the recorded parameter via the 
pre-processing, exchange or post-processing of data. If conducted, auto 
zeroing shall be performed against a traceable zero standard similar to the 
one used to zero the analyser. It is strongly recommended to initiate 
PEMS system maintenance during periods of zero vehicle speed.  
5.3. Test end  
The end of the test is reached when the vehicle has completed the trip and 
the ignition is turned off. Excessive idling of the engine after the 
completion of the trip shall be avoided. The data recording shall 
continue until the response time of the sampling systems has elapsed.  
▼B 
6. POST-TEST PROCEDURE  
6.1. Checking the analysers for measuring gaseous emissions  
The zero and span of the analysers of gaseous components shall be 
checked by using calibration gases identical to the ones applied under 
point 4.5 to evaluate the analyser's zero and response drift compared to 
the pre-test calibration. It is permissible to zero the analyser prior to 
verifying the span drift, if the zero drift was determined to be within 
the permissible range. The post-test drift check shall be completed as  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 143  
soon as possible after the test and before the PEMS, or individual 
analysers or sensors, are turned off or have switched into a non- 
operating mode. The difference between the pre-test and post-test 
results shall comply with the requirements specified in Table 2.  
Table 2  
Permissible analyser drift over a PEMS test  
▼M1 
Pollutant  Absolute Zero response drift  Absolute Span response drift (  1 ) 
CO  2 ≤ 2 000 ppm per test  ≤ 2 % of reading or ≤ 2 000 ppm per test, whichever 
is larger  
CO ≤ 75 ppm per test  ≤ 2 % of reading or ≤ 75 ppm per test, whichever is 
larger  
NO  X ≤ 5 ppm per test  ≤ 2 % of reading or ≤ 5 ppm per test, whichever is 
larger  
CH  4 ≤ 10 ppm C  1 per test  ≤ 2 % of reading or ≤ 10 ppm C  1 per test, whichever 
is larger  
THC  ≤ 10 ppm C  1 per test  ≤ 2 % of reading or ≤ 10 ppm C  1 per test, whichever 
is larger  
( 1 ) If the zero drift is within the permissible range, it is permissible to zero the analyser prior to verifying the span drift.  
▼B 
If the difference between the pre-test and post-test results for the zero and 
span drift is higher than permitted, all test results shall be voided and the 
test repeated.  
▼M1 
6.2. Checking the analyser for measuring particle emissions  
The zero level of the analyser shall be recorded in accordance with 
point 4.6.  
▼B 
6.3. Checking the on-road emission measurements  
The calibrated range of the analysers shall account at least for 90 % of the 
concentration values obtained from 99 % of the measurements of the 
valid parts of the emissions test. It is permissible that 1 % of the total 
number of measurements used for evaluation exceeds the calibrated range 
of the analysers by up to a factor of two. If these requirements are not 
met, the test shall be voided.  ▼B

3. LINEARITY VERIFICATION  
3.1. General  
►M1 The accuracy and linearity of analysers, flow-measuring instru ­
ments, sensors and signals, shall be traceable to international or 
national standards. ◄ Any sensors or signals that are not directly 
traceable, e.g., simplified flow-measuring instruments shall be calibrated 
alternatively against chassis dynamometer laboratory equipment that has 
been calibrated against international or national standards.  
3.2. Linearity requirements  
All analysers, flow-measuring instruments, sensors and signals shall 
comply with the linearity requirements given in Table 1. If air flow, 
fuel flow, the air-to-fuel ratio or the exhaust mass flow rate is obtained 
from the ECU, the calculated exhaust mass flow rate shall meet the 
linearity requirements specified in Table 1.

( 4 ) To be updated based on error propagation and traceability charts.  
3.3. Frequency of linearity verification  
The linearity requirements pursuant to point 3.2 shall be verified:  
(a) for each gas analyser at least every 12 months or whenever a system 
repair or component change or modification is made that could 
influence the calibration;  
(b) for other relevant instruments, such as PN analysers, exhaust mass 
flow meters and traceably calibrated sensors, whenever damage is 
observed, as required by internal audit procedures or by the 
instrument manufacturer but no longer than one year before the 
actual test.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 147  
The linearity requirements pursuant to point 3.2 for sensors or ECU 
signals that are not directly traceable shall be performed with a 
traceably calibrated measurement device on the chassis dynamometer 
once for each PEMS-vehicle setup.  
▼B 
3.4. Procedure of linearity verification  
3.4.1.  General requirements  
The relevant analysers, instruments and sensors shall be brought to their 
normal operating condition according to the recommendations of their 
manufacturer. The analysers, instruments and sensors shall be operated 
at their specified temperatures, pressures and flows.  
3.4.2.  General procedure  
The linearity shall be verified for each normal operating range by 
executing the following steps:  
(a) The analyser, flow-measuring instrument or sensor shall be set to zero 
by introducing a zero signal. For gas analysers, purified synthetic air 
or nitrogen shall be introduced to the analyser port via a gas path that 
is as direct and short as possible.  
(b) The analyser, flow-measuring instrument or sensor shall be spanned 
by introducing a span signal. For gas analysers, an appropriate span 
gas shall be introduced to the analyser port via a gas path that is as 
direct and short as possible.  
(c) The zero procedure of (a) shall be repeated.  
(d) The linearity shall be verified by introducing at least 10, approxi ­
mately equally spaced and valid, reference values (including zero). 
The reference values with respect to the concentration of components, 
the exhaust mass flow rate or any other relevant parameter shall be 
chosen to match the range of values expected during the emissions 
test. For measurements of exhaust mass flow, reference points below 
5 % of the maximum calibration value can be excluded from the 
linearity verification.  
(e) For gas analysers, known gas concentrations in accordance with point 
5 shall be introduced to the analyser port. Sufficient time for signal 
stabilisation shall be given.  
(f) The values under evaluation and, if needed, the reference values shall 
be recorded at a constant frequency of at least 1.0 Hz over a period of 
30 seconds.  
(g) The arithmetic mean values over the 30 seconds period shall be used 
to calculate the least squares linear regression parameters, with the 
best-fit equation having the form:  
y ¼ a 1 x þ a 0 
where:  
y is the actual value of the measurement system  
a 1 is the slope of the regression line  
x is the reference value  
a 0 is the  y intercept of the regression line  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 148  
The standard error of estimate (SEE) of  y on x and the coefficient of 
determination (r  2 ) shall be calculated for each measurement parameter 
and system.  
(h) The linear regression parameters shall meet the requirements specified 
in Table 1.  
3.4.3.  Requirements for linearity verification on a chassis dynamometer  
Non-traceable flow-measuring instruments, sensors or ECU signals that 
cannot directly be calibrated according to traceable standards, shall be 
calibrated on a chassis dynamometer. The procedure shall follow as far 
as applicable, the requirements of Annex 4a to UN/ECE Regulation 
No 83. If necessary, the instrument or sensor to be calibrated shall be 
installed on the test vehicle and operated according to the requirements of 
Appendix 1. The calibration procedure shall follow whenever possible the 
requirements of point 3.4.2; at least 10 appropriate reference values shall 
be selected as to ensure that at least 90 % of the maximum value expected 
to occur during the RDE test is covered.  
If a not directly traceable flow-measuring instrument, sensor or ECU 
signal for determining exhaust flow is to be calibrated, a traceably cali ­
brated reference exhaust mass flow meter or the CVS shall be attached to 
the vehicle’s tailpipe. It shall be ensured that the vehicle exhaust is 
accurately measured by the exhaust mass flow meter according to point 
3.4.3 of Appendix 1. The vehicle shall be operated by applying constant 
throttle at a constant gear selection and chassis dynamometer load.  
4. ANALYSERS FOR MEASURING GASEOUS COMPONENTS  
4.1. Permissible types of analysers  
4.1.1.  Standard analysers  
The gaseous components shall be measured with analysers specified in 
points 1.3.1 to 1.3.5 of Appendix 3, Annex 4A to UN/ECE Regulation 
No 83, 07 series of amendments. If an NDUV analyser measures both 
NO and NO  2 , a NO  2 /NO converter is not required.  
4.1.2.  Alternative analysers  
Any analyser not meeting the design specifications of point 4.1.1 is 
permissible provided that it fulfils the requirements of point 4.2. The 
manufacturer shall ensure that the alternative analyser achieves an 
equivalent or higher measurement performance compared to a standard 
analyser over the range of pollutant concentrations and co-existing gases 
that can be expected from vehicles operated with permissible fuels under 
moderate and extended conditions of valid RDE testing as specified in 
points 5, 6 and 7 of this Annex. Upon request, the manufacturer of the 
analyser shall submit in writing supplemental information, demonstrating 
that the measurement performance of the alternative analyser is 
consistently and reliably in line with the measurement performance of 
standard analysers. Supplemental information shall contain:  
(a) a description of the theoretical basis and the technical components of 
the alternative analyser;  
(b) a demonstration of equivalency with the respective standard analyser 
specified in point 4.1.1 over the expected range of pollutant concen ­
trations and ambient conditions of the type-approval test defined in 
Annex 4a to UN/ECE Regulation No 83, 07 series of amendments as 
well as a validation test as described in point 3 of Appendix 3 for a 
vehicle equipped with a spark-ignition and compression-ignition 
engine; the manufacturer of the analyser shall demonstrate the 
significance of equivalency within the permissible tolerances given 
in point 3.3 of Appendix 3.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 149  
(c) a demonstration of equivalency with the respective standard analyser 
specified in point 4.1.1 with respect to the influence of atmospheric 
pressure on the measurement performance of the analyser; the demon ­
stration test shall determine the response to span gas having a concen ­
tration within the analyser range to check the influence of atmos ­
pheric pressure under moderate and extended altitude conditions 
defined in point 5.2 of this Annex. Such a test can be performed 
in an altitude environmental test chamber.  
(d) a demonstration of equivalency with the respective standard analyser 
specified in point 4.1.1 over at least three on-road tests that fulfil the 
requirements of this Annex.  
(e) a demonstration that the influence of vibrations, accelerations and 
ambient temperature on the analyser reading does not exceed the 
noise requirements for analysers set out in point 4.2.4.  
Approval authorities may request additional information to substantiate 
equivalency or refuse approval if measurements demonstrate that an alter ­
native analyser is not equivalent to a standard analyser.  
4.2. Analyser specifications  
4.2.1.  General  
In addition to the linearity requirements defined for each analyser in point 
3, the compliance of analyser types with the specifications laid down in 
points 4.2.2 to 4.2.8 shall be demonstrated by the analyser manufacturer. 
Analysers shall have a measuring range and response time appropriate to 
measure with adequate accuracy the concentrations of the exhaust gas 
components at the applicable emissions standard under transient and 
steady state conditions. The sensitivity of the analysers to shocks, 
vibration, aging, variability in temperature and air pressure as well as 
electromagnetic interferences and other impacts related to vehicle and 
analyser operation shall be limited as far as possible.  
4.2.2.  Accuracy  
The accuracy, defined as the deviation of the analyser reading from the 
reference value, shall not exceed 2 % of reading or 0.3 % of full scale, 
whichever is larger.  
4.2.3.  Precision  
The precision, defined as 2.5 times the standard deviation of 10 repetitive 
responses to a given calibration or span gas, shall be no greater than 1 % 
of the full scale concentration for a measurement range equal or above 
155 ppm (or ppmC  1 ) and 2 % of the full scale concentration for a 
measurement range of below 155 ppm (or ppmC  1 ). 
4.2.4.  Noise  
The noise, defined as two times the root mean square of ten standard 
deviations, each calculated from the zero responses measured at a 
constant recording frequency of at least 1.0 Hz during a period of 30 
seconds, shall not exceed 2 % of full scale. Each of the 10 measurement 
periods shall be interspersed with an interval of 30 seconds in which the 
analyser is exposed to an appropriate span gas. Before each sampling 
period and before each span period, sufficient time shall be given to 
purge the analyser and the sampling lines.  
4.2.5.  Zero response drift  
The drift of the zero response, defined as the mean response to a zero gas 
during a time interval of at least 30 seconds, shall comply with the 
specifications given in Table 2.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 150  
4.2.6.  Span response drift  
The drift of the span response, defined as the mean response to a span gas 
during a time interval of at least 30 seconds, shall comply with the 
specifications given in Table 2.

The rise time, defined as the time between the 10 per cent and 90 per cent 
response of the final reading ( t 90 – t 10 ; see point 4.4), shall not exceed 
3 seconds.  
4.2.8.  Gas drying  
Exhaust gases may be measured wet or dry. A gas-drying device, if used, 
shall have a minimal effect on the composition of the measured gases. 
Chemical dryers are not permitted.  
4.3. Additional requirements  
4.3.1.  General  
The provisions in points 4.3.2 to 4.3.5 define additional performance 
requirements for specific analyser types and apply only to cases, in 
which the analyser under consideration is used for RDE emission 
measurements.  
4.3.2.  Efficiency test for NO  X converters  
If a NO  X converter is applied, for example to convert NO  2 into NO for 
analysis with a chemiluminescence analyser, its efficiency shall be tested 
by following the requirements of point 2.4 of Appendix 3 of Annex 4a to 
UN/ECE Regulation No 83, 07 series of amendments. The efficiency of 
the NO  X converter shall be verified no longer than one month before the 
emissions test.  
4.3.3.  Adjustment of the Flame Ionisation Detector (FID)  
(a) Optimization of the detector response  
If hydrocarbons are measured, the FID shall be adjusted at intervals 
specified by the analyser manufacturer by following point 2.3.1 of  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 151  
Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of 
amendments. A propane-in-air or propane-in-nitrogen span gas shall 
be used to optimize the response in the most common operating 
range.  
(b) Hydrocarbon response factors  
If hydrocarbons are measured, the hydrocarbon response factor of the 
FID shall be verified by following the provisions of point 2.3.3 of 
Appendix 3 of Annex 4a to UN/ECE Regulation No 83, 07 series of 
amendments, using propane-in-air or propane-in-nitrogen as span 
gases and purified synthetic air or nitrogen as zero gases, respectively.  
(c) Oxygen interference check  
The oxygen interference check shall be performed when introducing a 
FID into service and after major maintenance intervals. A measuring 
range shall be chosen in which the oxygen interference check gases 
fall in the upper 50 per cent. The test shall be conducted with the 
oven temperature set as required. The specifications of the oxygen 
interference check gases are described in point 5.3.  
The following procedure applies:  
(i) The analyser shall be set at zero;  
(ii) The analyser shall be spanned with a 0 per cent oxygen blend 
for positive ignition engines and a 21 per cent oxygen blend for 
compression ignition engines;  
(iii) The zero response shall be rechecked. If it has changed by 
more than 0.5 per cent of full scale, steps (i) and (ii) shall be 
repeated;  
(iv) The 5 per cent and 10 per cent oxygen interference check gases 
shall be introduced;  
(v) The zero response shall be rechecked. If it has changed by 
more than ±1 per cent of full scale, the test shall be repeated;  
(vi) The oxygen interference  E O2 shall be calculated for each 
oxygen interference check gas in step (iv) as follows:  
E O2 ¼ ðc ref;d Ä cÞ 
ðc ref;d Þ Ü 100 
where the analyser response is:  
c ¼ ðc ref;d Ü c FS;b Þ 
c m;b Ü c m;b 
c FS;d 
where:  
c ref,b is the reference HC concentration in step (ii) [ppmC  1 ] ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 152  
c ref,d is the reference HC concentration in step (iv) [ppmC  1 ] 
c FS,b is the full scale HC concentration in step (ii) [ppmC  1 ] 
c FS,d is the full scale HC concentration in step (iv) [ppmC  1 ] 
c m,b is the measured HC concentration in step (ii) [ppmC  1 ] 
c m,d is the measured HC concentration in step (iv) [ppmC  1 ] 
(vii) The oxygen interference  E O2 shall be less than ±1.5 per cent for 
all required oxygen interference check gases.  
(viii) If the oxygen interference  E O2 is higher than ±1.5 per cent, 
corrective action may be taken by incrementally adjusting the 
air flow (above and below the manufacturer's specifications), 
the fuel flow and the sample flow.  
(ix) The oxygen interference check shall be repeated for each new 
setting.  
4.3.4.  Conversion efficiency of the non-methane cutter (NMC)  
If hydrocarbons are analysed, a NMC can be used to remove non- 
methane hydrocarbons from the gas sample by oxidizing all hydrocarbons 
except methane. Ideally, the conversion for methane is 0 per cent and for 
the other hydrocarbons represented by ethane is 100 per cent. For the 
accurate measurement of NMHC, the two efficiencies shall be determined 
and used for the calculation of the NMHC emissions (see point 9.2 of 
Appendix 4). It is not necessary to determine the methane conversion 
efficiency in case the NMC-FID is calibrated according to method (b) 
in point 9.2 of Appendix 4 by passing the methane/air calibration gas 
through the NMC.  
(a) Methane conversion efficiency  
Methane calibration gas shall be flown through the FID with and 
without bypassing the NMC; the two concentrations shall be 
recorded. The methane efficiency shall be determined as:  
E M ¼ 1 Ä c HCðw=NMCÞ 
c HCðw=oNMCÞ 
where:  
c HC(w/NMC)  is the HC concentration with CH  4 flowing through the 
NMC [ppmC  1 ] 
c HC(w/o NMC)  is the HC concentration with CH  4 bypassing the NMC 
[ppmC  1 ] 
(b) Ethane conversion efficiency  
Ethane calibration gas shall be flown through the FID with and 
without bypassing the NMC; the two concentrations shall be 
recorded. The ethane efficiency shall be determined as:  
E E ¼ 1 Ä c HCðw=NMCÞ 
c HCðw=oNMCÞ 
where:  
c HC(w/NMC)  is the HC concentration with C  2 H 6 flowing through 
the NMC [ppmC  1 ] ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 153  
c HC(w/o NMC)  is the HC concentration with C  2 H 6 bypassing the 
NMC [ppmC  1 ] 
4.3.5.  Interference effects  
(a) General  
Other gases than the ones being analysed can affect the analyser 
reading. A check for interference effects and the correct functionality 
of analysers shall be performed by the analyser manufacturer prior to 
market introduction at least once for each type of analyser or device 
addressed in points (b) to (f).  
(b) CO analyser interference check  
Water and CO  2 can interfere with the measurements of the CO 
analyser. Therefore, a CO  2 span gas having a concentration of 80 
to 100 per cent of full scale of the maximum operating range of the 
CO analyser used during the test shall be bubbled through water at 
room temperature and the analyser response recorded. The analyser 
response shall not be more than 2 per cent of the mean CO concen ­
tration expected during normal on-road testing or ± 50 ppm, 
whichever is larger. The interference check for H  2 O and CO  2 may 
be run as separate procedures. If the H  2 O and CO  2 levels used for 
the interference check are higher than the maximum levels expected 
during the test, each observed interference value shall be scaled 
down by multiplying the observed interference with the ratio of 
the maximum expected concentration value during the test and the 
actual concentration value used during this check. Separate inter ­
ference checks with concentrations of H  2 O that are lower than the 
maximum concentration expected during the test may be run and the 
observed H  2 O interference shall be scaled up by multiplying the 
observed interference with the ratio of the maximum H  2 O concen ­
tration value expected during the test and the actual concentration 
value used during this check. The sum of the two scaled interference 
values shall meet the tolerance specified in this point.  
(c) NO  X analyser quench check  
The two gases of concern for CLD and HCLD analysers are CO  2 
and water vapour. The quench response to these gases is propor ­
tional to the gas concentrations. A test shall determine the quench at 
the highest concentrations expected during the test. If the CLD and 
HCLD analysers use quench compensation algorithms that utilize 
H 2 O or CO  2 measurement analysers or both, quench shall be 
evaluated with these analysers active and with the compensation 
algorithms applied.  
(i) CO  2 quench check  
A CO  2 span gas having a concentration of 80 to 100 per cent of 
the maximum operating range shall be passed through the 
NDIR analyser; the CO  2 value shall be recorded as A. The 
CO  2 span gas shall then be diluted by approximately 50 per 
cent with NO span gas and passed through the NDIR and CLD 
or HCLD; the CO  2 and NO values shall be recorded as B and 
C, respectively. The CO  2 gas flow shall then be shut off and 
only the NO span gas shall be passed through the CLD or 
HCLD; the NO value shall be recorded as D. The per cent 
quench shall be calculated as:  
E CO2 ¼ Ï 
1 Ä Í C Ü A 
ðD Ü AÞ Ä ðD Ü BÞ ÎB 
Ü 100 ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 154  
where:  
A is the undiluted CO  2 concentration measured with the NDIR 
[%] 
B is the diluted CO  2 concentration measured with the NDIR 
[%] 
C is the diluted NO concentration measured with the CLD or 
HCLD [ppm]  
D is the undiluted NO concentration measured with the CLD 
or HCLD [ppm]  
Alternative methods of diluting and quantifying of CO  2 and NO 
span gas values such as dynamic mixing/blending are permitted 
upon approval of the approval authority.  
(ii) Water quench check  
This check applies to measurements of wet gas concentrations 
only. The calculation of water quench shall consider dilution of 
the NO span gas with water vapour and the scaling of the water 
vapour concentration in the gas mixture to concentration levels 
that are expected to occur during an emissions test. A NO span 
gas having a concentration of 80 per cent to 100 per cent of full 
scale of the normal operating range shall be passed through the 
CLD or HCLD; the NO value shall be recorded as  D. The NO 
span gas shall then be bubbled through water at room 
temperature and passed through the CLD or HCLD; the NO 
value shall be recorded as  C. The analyser's absolute operating 
pressure and the water temperature shall be determined and 
recorded as E and F, respectively. The mixture's saturation 
vapour pressure that corresponds to the water temperature of 
the bubbler  F shall be determined and recorded as  G. The water 
vapour concentration  H [%] of the gas mixture shall be 
calculated as:  
▼C2 
H ¼ G 
E Ü 100 
▼B 
The expected concentration of the diluted NO-water vapour 
span gas shall be recorded as  D e after being calculated as:  
D e ¼ D Ü Ê 
1 Ä H 
100 Ì 
For diesel exhaust, the maximum concentration of water vapour 
in the exhaust gas (in per cent) expected during the test shall be 
recorded as  H m after being estimated, under the assumption of a 
fuel H/C ratio of 1.8/1, from the maximum CO  2 concentration 
in the exhaust gas A as follows:  
H m ¼ 0,9 Ü A 
The per cent water quench shall be calculated as:  
E H2O ¼ Í Ê D e Ä C 
D e Ì 
Ü Ê H m 
H Ì Î 
Ü 100 
where:  
D e is the expected diluted NO concentration [ppm]  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 155  
C is the measured diluted NO concentration [ppm]  
H m is the maximum water vapour concentration [%]  
H is the actual water vapour concentration [%]  
(iii) Maximum allowable quench  
The combined CO  2 and water quench shall not exceed 2 per 
cent of full scale.  
(d) Quench check for NDUV analysers  
Hydrocarbons and water can positively interfere with NDUV 
analysers by causing a response similar to that of NO  X . The manu ­
facturer of the NDUV analyser shall use the following procedure to 
verify that quench effects are limited:  
(i) The analyser and chiller shall be set up by following the 
operating instructions of the manufacturer; adjustments 
should be made as to optimise the analyser and chiller 
performance.  
(ii) A zero calibration and span calibration at concentration values 
expected during emissions testing shall be performed for the 
analyser.  
(iii) A NO  2 calibration gas shall be selected that matches as far as 
possible the maximum NO  2 concentration expected during 
emissions testing.  
(iv) The NO  2 calibration gas shall overflow at the gas sampling 
system's probe until the NO  X response of the analyser has 
stabilised.  
(v) The mean concentration of the stabilized NO  X recordings over 
a period of 30 s shall be calculated and recorded as NO  X,ref . 
(vi) The flow of the NO  2 calibration gas shall be stopped and the 
sampling system saturated by overflowing with a dew point 
generator's output, set at a dew point of 50 °C. The dew point 
generator's output shall be sampled through the sampling 
system and chiller for at least 10 minutes until the chiller is 
expected to be removing a constant rate of water.  
(vii) Upon completion of (iv), the sampling system shall again be 
overflown by the NO  2 calibration gas used to establish NO  X,ref 
until the total NO  X response has stabilized.  
(viii) The mean concentration of the stabilized NO  X recordings over 
a period of 30 s shall be calculated and recorded as NO  X,m . 
(ix) NO  X,m shall be corrected to NO  X,dry based upon the residual 
water vapour that passed through the chiller at the chiller's 
outlet temperature and pressure.  
The calculated NO  X,dry shall at least amount to 95 % of NO  X,ref . ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 156  
(e) Sample dryer  
A sample dryer removes water, which can otherwise interfere with 
the NO  X measurement. For dry CLD analysers, it shall be demon ­
strated that at the highest expected water vapour concentration  H m 
the sample dryer maintains the CLD humidity at ≤ 5 g water/kg dry 
air (or about 0.8 per cent H  2 O), which is 100 per cent relative 
humidity at 3.9 °C and 101.3 kPa or about 25 per cent relative 
humidity at 25 °C and 101.3 kPa. Compliance may be demonstrated 
by measuring the temperature at the outlet of a thermal sample dryer 
or by measuring the humidity at a point just upstream of the CLD. 
The humidity of the CLD exhaust might also be measured as long as 
the only flow into the CLD is the flow from the sample dryer.  
(f) Sample dryer NO  2 penetration  
Liquid water remaining in an improperly designed sample dryer can 
remove NO  2 from the sample. If a sample dryer is used in 
combination with a NDUV analyser without an NO  2 /NO converter 
upstream, water could therefore remove NO  2 from the sample prior 
to the NO  X measurement. The sample dryer shall allow for 
measuring at least 95 per cent of the NO  2 contained in a gas that 
is saturated with water vapour and consists of the maximum NO  2 
concentration expected to occur during emission testing.  
4.4. Response time check of the analytical system  
For the response time check, the settings of the analytical system shall be 
exactly the same as during the emissions test (i.e. pressure, flow rates, 
filter settings in the analysers and all other parameters influencing the 
response time). The response time shall be determined with gas switching 
directly at the inlet of the sample probe. The gas switching shall be done 
in less than 0.1 second. The gases used for the test shall cause a concen ­
tration change of at least 60 per cent full scale of the analyser.  
The concentration trace of each single gas component shall be recorded. 
The delay time is defined as the time from the gas switching ( t 0 ) until the 
response is 10 per cent of the final reading ( t 10 ). The rise time is defined 
as the time between 10 per cent and 90 per cent response of the final 
reading ( t 90 – t 10 ). The system response time ( t 90 ) consists of the delay 
time to the measuring detector and the rise time of the detector.  
For time alignment of the analyser and exhaust flow signals, the trans ­
formation time is defined as the time from the change ( t 0 ) until the 
response is 50 per cent of the final reading ( t 50 ). 
The system response time shall be ≤ 12 s with a rise time of ≤ 3 seconds 
for all components and all ranges used. When using a NMC for the 
measurement of NMHC, the system response time may exceed 12 
seconds.  
5. GASES  
5.1. General  
The shelf life of calibration and span gases shall be respected. Pure and 
mixed calibration and span gases shall fulfil the specifications of points 
3.1 and 3.2 of Appendix 3 of Annex 4A to UN/ECE Regulation No 83, 
07 series of amendments. In addition, NO  2 calibration gas is permissible. 
The concentration of the NO  2 calibration gas shall be within two per cent 
of the declared concentration value. The amount of NO contained in the 
NO  2 calibration gas shall not exceed 5 per cent of the NO  2 content.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 157  
5.2. Gas dividers  
Gas dividers, i.e., precision blending devices that dilute with purified N  2 
or synthetic air, can be used to obtain calibration and span gases. The 
accuracy of the gas divider shall be such that the concentration of the 
blended calibration gases is accurate to within ± 2 per cent. The verifi ­
cation shall be performed at between 15 and 50 per cent of full scale for 
each calibration incorporating a gas divider. An additional verification 
may be performed using another calibration gas, if the first verification 
has failed.  
Optionally, the gas divider may be checked with an instrument which by 
nature is linear, e.g. using NO gas in combination with a CLD. The span 
value of the instrument shall be adjusted with the span gas directly 
connected to the instrument. The gas divider shall be checked at the 
settings typically used and the nominal value shall be compared with 
the concentration measured by the instrument. The difference shall in 
each point be within ±1 per cent of the nominal concentration value.  
5.3. Oxygen interference check gases  
Oxygen interference check gases consist of a blend of propane, oxygen 
and nitrogen and shall contain propane at a concentration of 350 ± 75 
ppmC  1 . The concentration shall be determined by gravimetric methods, 
dynamic blending or the chromatographic analysis of total hydrocarbons 
plus impurities. The oxygen concentrations of the oxygen interference 
check gases shall meet the requirements listed in Table 3; the 
remainder of the oxygen interference check gas shall consist of purified 
nitrogen.

6. ANALYSERS FOR MEASURING (SOLID) PARTICLE EMISSIONS  
▼B 
This sections will define future requirement for analysers for measuring 
particle number emissions, once their measurement becomes mandatory.  
▼M1 
6.1. General  
The PN analyser shall consist of a pre-conditioning unit and a particle 
detector that counts with 50 % efficiency from approximately 23 nm. It is 
permissible that the particle detector also pre-conditions the aerosol. The 
sensitivity of the analysers to shocks, vibration, aging, variability in 
temperature and air pressure as well as electromagnetic interferences 
and other impacts related to vehicle and analyser operation shall be 
limited as far as possible and shall be clearly stated by the equipment 
manufacturer in its support material. The PN analyser shall only be used 
within its manufacturer’s declared parameters of operation.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 158  
Figure 1  
Example of a PN analyser setup: Dotted lines depict optional parts. 
EFM = Exhaust mass Flow Meter, d = inner diameter, PND = 
Particle Number Diluter.
  
The PN analyser shall be connected to the sampling point via a sampling 
probe which extracts a sample from the centreline of the tailpipe tube. As 
specified in point 3.5 of Appendix 1, if particles are not diluted at the 
tailpipe, the sampling line shall be heated to a minimum temperature of 
373 K (100 °C) until the point of first dilution of the PN analyser or the 
particle detector of the analyser. The residence time in the sampling line 
shall be less than 3 s.  
All parts in contact with the sampled exhaust gas shall be always kept at 
a temperature that avoids condensation of any compound in the device. 
This can be achieved, e.g. by heating at a higher temperature and diluting 
the sample or oxidizing the (semi)volatile species.  
The PN analyser shall include a heated section at wall temperature ≥ 573 
K. The unit shall control the heated stages to constant nominal operating 
temperatures, within a tolerance of ± 10 K and provide an indication of 
whether or not heated stages are at their correct operating temperatures. 
Lower temperatures are acceptable as long as the volatile particle removal 
efficiency fulfils the specifications of 6.4.  
Pressure, temperature and other sensors shall monitor the proper operation 
of the instrument during operation and trigger a warning or message in 
case of malfunction.  
The delay time of the PN analyser shall be ≤ 5 s.  
The PN analyser (and/or particle detector) shall have a rise time of ≤ 3,5 s.  
Particle concentration measurements shall be reported normalised to 273 K 
and 101,3 kPa. If necessary, the pressure and/or temperature at the inlet of 
the detector shall be measured and reported for the purposes of normalizing 
the particle concentration.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 159  
PN systems that comply with the calibration requirements of the UNECE 
Regulations 83 or 49 or GTR 15 automatically comply with the cali ­
bration requirements of this Annex.  
6.2. Efficiency requirements  
The complete PN analyser system including the sampling line shall fulfil 
the efficiency requirements of Table 3a.  
Table 3a  
PN analyser (including the sampling line) system efficiency requirements  
d p [nm]  Sub-23  23  30  50  70  100  200  
E(d  p ) PN analyser  To be 
determined  0,2 – 0,6  0,3 – 1,2  0,6 – 1,3  0,7 – 1,3  0,7 – 1,3  0,5 – 2,0  
Efficiency E(d  p ) is defined as the ratio in the readings of the PN analyser 
system to a reference Condensation Particle Counter (CPC)’s (d  50 % = 10 
nm or lower, checked for linearity and calibrated with an electrometer) or 
an Electrometer’s number concentration measuring in parallel mono ­
disperse aerosol of mobility diameter d  p and normalized at the same 
temperature and pressure conditions.  
The efficiency requirements will need to be adapted, in order to make 
sure that the efficiency of the PN analysers remains consistent with the 
margin PN. The material should be thermally stable soot-like (e.g. spark 
discharged graphite or diffusion flame soot with thermal pre-treatment). If 
the efficiency curve is measured with a different aerosol (e.g. NaCl), the 
correlation to the soot-like curve must be provided as a chart, which 
compares the efficiencies obtained using both test aerosols. The 
differences in the counting efficiencies have to be taken into account 
by adjusting the measured efficiencies based on the provided chart to 
give soot-like aerosol efficiencies. The correction for multiply charged 
particles should be applied and documented but shall not exceed 10 %. 
These efficiencies refer to the PN analysers with the sampling line. The 
PN analyser can also be calibrated in parts (i.e. the pre-conditioning unit 
separately from the particle detector) as long as it is proven that PN 
analyser and the sampling line together fulfil the requirements of Table 
3a. The measured signal from the detector shall be > 2 times the limit of 
detection (here defined as the zero level plus 3 standard deviations).  
6.3. Linearity requirements  
The PN analyser including the sampling line shall fulfil the linearity 
requirements of point 3.2 in Appendix 2 using monodisperse or poly ­
disperse soot-like particles. The particle size (mobility diameter or count 
median diameter) should be larger than 45 nm. The reference instrument 
shall be an Electrometer or a Condensation Particle Counter (CPC) with 
d 50 = 10 nm or lower, verified for linearity. Alternatively, a particle 
number system compliant with UNECE Regulation 83.  
In addition the differences of the PN analyser from the reference 
instrument at all points checked (except the zero point) shall be within 
15 % of their mean value. At least 5 points equally distributed (plus the 
zero) shall be checked. The maximum checked concentration shall be the 
maximum allowed concentration of the PN analyser.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 160  
If the PN analyser is calibrated in parts, then the linearity can be checked 
only for the PN detector, but the efficiencies of the rest parts and the 
sampling line have to be considered in the slope calculation.  
6.4. Volatile removal efficiency  
The system shall achieve > 99 % removal of ≥ 30 nm tetracontane 
(CH  3 (CH  2 ) 38 CH  3 ) particles with an inlet concentration of ≥ 10 000 
particles per cubic-centimetre at the minimum dilution.  
The system shall also achieve a > 99 % removal efficiency of poly ­
disperse alcane (decane or higher) or emery oil with count median 
diameter > 50 nm and mass > 1 mg/m  3 . 
The volatile removal efficiency with tetracontane and/or polydisperse 
alcane or oil have to be proven only once for the instrument family. 
The instrument manufacturer though has to provide the maintenance or 
replacement interval that ensures that the removal efficiency does not 
drop below the technical requirements. If such information is not 
provided, the volatile removal efficiency has to be checked yearly for 
each instrument.

7. INSTRUMENTS FOR MEASURING EXHAUST MASS FLOW  
7.1. General  
Instruments, sensors or signals for measuring the exhaust mass flow rate 
shall have a measuring range and response time appropriate for the 
accuracy required to measure the exhaust mass flow rate under 
transient and steady state conditions. The sensitivity of instruments, 
sensors and signals to shocks, vibration, aging, variability in temperature, 
ambient air pressure, electromagnetic interferences and other impacts 
related to vehicle and instrument operation shall be on a level as to 
minimize additional errors.  
7.2. Instrument specifications  
The exhaust mass flow rate shall be determined by a direct measurement 
method applied in either of the following instruments:  
(a) Pitot-based flow devices;  
(b) Pressure differential devices like flow nozzle (details see ISO 5167);  
(c) Ultrasonic flow meter;  
(d) Vortex flow meter.  
Each individual exhaust mass flow meter shall fulfil the linearity 
requirements set out in point 3. Furthermore, the instrument manufacturer 
shall demonstrate the compliance of each type of exhaust mass flow meter 
with the specifications in points 7.2.3 to 7.2.9.  
It is permissible to calculate the exhaust mass flow rate based on air flow 
and fuel flow measurements obtained from traceably calibrated sensors if 
these fulfil the linearity requirements of point 3, the accuracy 
requirements of point 8 and if the resulting exhaust mass flow rate is 
validated according to point 4 of Appendix 3.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 161  
In addition, other methods that determine the exhaust mass flow rate 
based on not directly traceable instruments and signals, such as simplified 
exhaust mass flow meters or ECU signals are permissible if the resulting 
exhaust mass flow rate fulfils the linearity requirements of point 3 and is 
validated according to point 4 of Appendix 3.  
7.2.1.  Calibration and verification standards  
The measurement performance of exhaust mass flow meters shall be

The compliance of exhaust mass flow meters with points 7.2.3 and 7.2.9 
shall be verified no longer than one year before the actual test.  
7.2.3.  Accuracy  
The accuracy, defined as the deviation of the EFM reading from the 
reference flow value, shall not exceed ± 2 percent of the reading, 
0,5 % of full scale or ± 1,0 per cent of the maximum flow at which 
the EFM has been calibrated, whichever is larger.  
7.2.4.  Precision  
The precision, defined as 2,5 times the standard deviation of 10 repetitive 
responses to a given nominal flow, approximately in the middle of the 
calibration range, shall not exceed 1 per cent of the maximum flow at 
which the EFM has been calibrated.  
7.2.5.  Noise

deviations, each calculated from the zero responses measured at a 
constant recording frequency of at least 1,0 Hz during a period of 30 
seconds, shall not exceed 2 per cent of the maximum calibrated flow 
value. Each of the 10 measurement periods shall be interspersed with 
an interval of 30 seconds in which the EFM is exposed to the 
maximum calibrated flow.  
7.2.6.  Zero response drift  
The zero response drift is defined as the mean response to zero flow 
during a time interval of at least 30 seconds. The zero response drift 
can be verified based on the reported primary signals, e.g., pressure. 
The drift of the primary signals over a period of 4 hours shall be less 
than ±2 per cent of the maximum value of the primary signal recorded at 
the flow at which the EFM was calibrated.  
7.2.7.  Span response drift

of the primary signals over a period of 4 hours shall be less than ± 2 per 
cent of the maximum value of the primary signal recorded at the flow at 
which the EFM was calibrated.  
7.2.8.  Rise time  
The rise time of the exhaust flow instruments and methods should match 
as far as possible the rise time of the gas analysers as specified in 
point 4.2.7 but shall not exceed 1 second.  ▼B

7.2.9.  Response time check  
The response time of exhaust mass flow meters shall be determined by 
applying similar parameters as those applied for the emissions test (i.e., 
pressure, flow rates, filter settings and all other response time influences). 
The response time determination shall be done with gas switching directly 
at the inlet of the exhaust mass flow meter. The gas flow switching shall 
be done as fast as possible, but highly recommended in less than 0,1 
second. The gas flow rate used for the test shall cause a flow rate change 
of at least 60 per cent full scale of the exhaust mass flow meter. The gas 
flow shall be recorded. The delay time is defined as the time from the gas

90 per cent response ( t 90 – t 10 ) of the final reading. The response time 
(t 90 ) is defined as the sum of the delay time and the rise time. The 
exhaust mass flow meter response time ( t 90 ) shall be ≤ 3 seconds with 
a rise time ( t 90 – t 10 ) of ≤ 1 second in accordance with point 7.2.8.

The PEMS shall be installed and prepared according to the requirements 
of Appendix 1. The PEMS installation shall be kept unchanged in the 
time period between the validation and the RDE test.  
3.2.2.  Test conditions  
The validation test shall be conducted on a chassis dynamometer, as far 
as applicable, under type approval conditions by following the 
requirements of Annex 4a to UN/ECE Regulation No 83, 07 series of 
amendments or any other adequate measurement method. It is recom ­

mass flow meters or the exhaust mass flow rate calculated from 
non-traceable sensors or ECU signals shall be validated under transient 
conditions for each test vehicle against a calibrated exhaust mass flow 
meter or the CVS. The validation can be executed without the installation

3. TIME CORRECTION OF PARAMETERS  
For the correct calculation of distance-specific emissions, the recorded 
traces of component concentrations, exhaust mass flow rate, vehicle 
speed, and other vehicle data shall be time corrected. To facilitate the 
time correction, data which are subject to time alignment shall be 
recorded either in a single data recording device or with a synchronised 
timestamp following point 5.1 of Appendix 1. The time correction and 
alignment of parameters shall be carried out by following the sequence 
described in points 3.1 to 3.3.  
3.1. Time correction of component concentrations  
The recorded traces of all component concentrations shall be time 
corrected by reverse shifting according to the transformation times of 
the respective analysers. The transformation time of analysers shall be 
determined according to point 4.4 of Appendix 2:  
c i;c ðt Ä Δt t;i Þ ¼ c i;r ðtÞ 
where:  
c i,c is the time-corrected concentration of component i as function of 
time t 
c i,r is the raw concentration of component i as function of time  t 
Δt t,i is the transformation time t of the analyser measuring component i  
3.2. Time correction of exhaust mass flow rate  
The exhaust mass flow rate measured with an exhaust flow meter shall be 
time corrected by reverse shifting according to the transformation time of 
the exhaust mass flow meter. The transformation time of the mass flow 
meter shall be determined according to point 4.4.9 of Appendix 2:

cross-correlation between the calculated exhaust mass flow rate and the 
exhaust mass flow rate measured following point 4 of Appendix 3.  
3.3. Time alignment of vehicle data  
Other data obtained from a sensor or the ECU shall be time-aligned by 
cross-correlation with suitable emission data (e.g., component concen ­
trations).  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 170  
3.3.1.  Vehicle speed from different sources  
To time align vehicle speed with the exhaust mass flow rate, it is first 
necessary to establish one valid speed trace. In case vehicle speed is 
obtained from multiple sources (e.g., the GPS, a sensor or the ECU), 
the speed values shall be time aligned by cross-correlation.  
3.3.2.  Vehicle speed with exhaust mass flow rate  
Vehicle speed shall be time aligned with the exhaust mass flow rate by 
cross-correlation between the exhaust mass flow rate and the product of 
vehicle speed and positive acceleration.  
3.3.3.  Further signals  
The time alignment of signals whose values change slowly and within a 
small value range, e.g. ambient temperature, can be omitted.  
▼M1 
4. COLD START  
Cold start is the period from the first start of the combustion engine until 
the point when the combustion engine has run cumulatively for 5 min. If 
the coolant temperature is determined, the cold start period ends once the 
coolant has reached 343 K (70 °C) for the first time but no later than the 
point at which the combustion engine has run cumulatively for 5 min 
after initial engine start.  
5. EMISSION MEASUREMENTS DURING STOP OF THE 
COMBUSTION ENGINE  
Any instantaneous emissions or exhaust flow measurements obtained 
while the combustion engine is deactivated shall be recorded. In a 
separate step, the recorded values shall afterward be set to zero by the 
data post processing. The combustion engine shall be considered as deac ­
tivated if two of the following criteria apply: the recorded engine speed is 
< 50 rpm; the exhaust mass flow rate is measured at < 3 kg/h; the 
measured exhaust mass flow rate drops to < 15 % of the typical 
steady-state exhaust mass flow rate at idling.  
▼B 
6. CONSISTENCY CHECK OF VEHICLE ALTITUDE  
In case well-reasoned doubts exist that a trip has been conducted above of 
the permissible altitude as specified in point 5.2 of this Annex and in case 
altitude has only been measured with a GPS, the GPS altitude data shall 
be checked for consistency and, if necessary, corrected. The consistency 
of data shall be checked by comparing the latitude, longitude and altitude 
data obtained from the GPS with the altitude indicated by a digital terrain 
model or a topographic map of suitable scale. Measurements that deviate 
by more than 40 m from the altitude depicted in the topographic map 
shall be manually corrected and marked.  
7. CONSISTENCY CHECK OF GPS VEHICLE SPEED  
The vehicle speed as determined by the GPS shall be checked for 
consistency by calculating and comparing the total trip distance with 
reference measurements obtained from either a sensor, the validated 
ECU or, alternatively, from a digital road network or topographic map. 
It is mandatory to correct GPS data for obvious errors, e.g., by applying a 
dead reckoning sensor, prior to the consistency check. The original and 
uncorrected data file shall be retained and any corrected data shall be 
marked. The corrected data shall not exceed an uninterrupted time period 
of 120 s or a total of 300 s. The total trip distance as calculated from the  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 171  
corrected GPS data shall deviate by no more than 4 % from the reference. 
If the GPS data do not meet these requirements and no other reliable 
speed source is available, the test results shall be voided.  
8. CORRECTION OF EMISSIONS  
8.1. Dry-wet correction  
If the emissions are measured on a dry basis, the measured concentrations 
shall be converted to a wet basis as:  
where:  
c wet ¼ k w Ü c dry 
c wet is the wet concentration of a pollutant in ppm or per cent volume  
c dry is the dry concentration of a pollutant in ppm or per cent volume  
k w is the dry-wet correction factor  
The following equation shall be used to calculate  k w : 
k w ¼ Í 1 
1 þ α Ü 0,005 Ü ðc co 2 þ c co Þ Ä k w1 Î 
Ü 1,008  
where:  
k w1 ¼ 1,608 Ü H a 
1 000 þ ð1,608 Ü H a Þ 
where:  
H a is the intake air humidity [g water per kg dry air]  
c CO2 is the dry CO  2 concentration [%]  
c CO is the dry CO concentration [%]  
α is the molar hydrogen ratio  
8.2. Correction of NO  x for ambient humidity and temperature  
NO  x emissions shall not be corrected for ambient temperature and 
humidity.  
9. DETERMINATION OF THE INSTANTANEOUS GASEOUS 
EXHAUST COMPONENTS  
9.1. Introduction  
The components in the raw exhaust shall be measured with the 
measurement and sampling analysers described in Appendix 2. The raw 
concentrations of relevant components shall be measured in accordance 
with Appendix 1. The data shall be time corrected and aligned in 
accordance with point 3.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 172  
9.2. Calculating NMHC and CH  4 concentrations  
For methane measurement using a NMC-FID, the calculation of NMHC 
depends on the calibration gas/method used for the zero/span calibration 
adjustment. When a FID is used for THC measurement without a NMC, 
it shall be calibrated with propane/air or propane/N  2 in the normal 
manner. For the calibration of the FID in series with a NMC, the 
following methods are permitted:  
(a) the calibration gas consisting of propane/air bypasses the NMC;  
(b) the calibration gas consisting of methane/air passes through the NMC.  
It is strongly recommended to calibrate the methane FID with methane/air 
through the NMC.  
In method (a), the concentrations of CH  4 and NMHC shall be calculated 
as follows:  
c CH  4 ¼ c HCðw=oNMCÞ Ü ð1 Ä E M Þ Ä c HCðw=NMCÞ 
ðE E Ä E M Þ 
c NMHC ¼ c HCðw=NMCÞ Ä c HCðw=oNMCÞ Ü ð1 Ä E E Þ 
r h Ü ðE E Ä E M Þ 
In method (b), the concentration of CH  4 and NMHC shall be calculated 
as follows:  
c CH  4 ¼ c HCðw=NMCÞ Ü r h Ü ð1 Ä E M Þ Ä c HCðw=oNMCÞ Ü ð1 Ä E E Þ 
r h ÜðE E Ä E M Þ 
c NMHC ¼ c HCðw=oNMCÞ Ü ð1 Ä E M Þ Ä c HCðw=NMCÞ Ü r h Ü ð1 Ä E M Þ 
ðE E Ä E M Þ 
where:  
c HC(w/oNMC)  is the HC concentration with CH  4 or C  2 H 6 bypassing the 
NMC [ppmC  1 ] 
c HC(w/NMC)  is the HC concentration with CH  4 or C  2 H 6 flowing 
through the NMC [ppmC  1 ] 
r h is the hydrocarbon response factor as determined in point 
4.3.3.(b) of Appendix 2  
E M is the methane efficiency as determined in point 4.3.4.(a) 
of Appendix 2  
E E is the ethane efficiency as determined in point 4.3.4(b) of 
Appendix 2  
If the methane FID is calibrated through the cutter (method b), then the 
methane conversion efficiency as determined in point 4.3.4.(a) of 
Appendix 2 is zero. The density used for calculating the NMHC mass 
shall be equal to that of total hydrocarbons at 273,15 K and 101,325 kPa 
and is fuel-dependent.  
10. DETERMINATION OF EXHAUST MASS FLOW RATE  
10.1.  Introduction  
The calculation of instantaneous mass emissions according to points 11 
and 12 requires determining the exhaust mass flow rate. The exhaust mass  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 173  
flow rate shall be determined by one of the direct measurement methods 
specified in point 7.2 of Appendix 2. Alternatively, it is permissible to 
calculate the exhaust mass flow rate as described in points 10.2 to 10.4.  
10.2.  Calculation method using air mass flow rate and fuel mass flow rate  
The instantaneous exhaust mass flow rate can be calculated from the air 
mass flow rate and the fuel mass flow rate as follows:  
q mew ;i ¼ q maw ;i þ q mf;i 
where:  
q mew,i is the instantaneous exhaust mass flow rate [kg/s]  
q maw,i is the instantaneous intake air mass flow rate [kg/s]  
q mf,i is the instantaneous fuel mass flow rate [kg/s]  
If the air mass flow rate and the fuel mass flow rate or the exhaust mass 
flow rate are determined from ECU recording, the calculated instan ­
taneous exhaust mass flow rate shall meet the linearity requirements 
specified for the exhaust mass flow rate in point 3 of Appendix 2 and 
the validation requirements specified in point 4.3 of Appendix 3.  
10.3.  Calculation method using air mass flow and air-to-fuel ratio  
The instantaneous exhaust mass flow rate can be calculated from the air 
mass flow rate and the air-to-fuel ratio as follows:  
q mew ;i ¼ q maw ;i Ü Í

Verification of trip dynamic conditions and calculation of the final RDE 
emissions result with method 1 (Moving Averaging Window)  
1. INTRODUCTION  
The Moving Averaging Window method provides an insight on the 
real-driving emissions (RDE) occurring during the test at a given scale. 
The test is divided in sub-sections (windows) and the subsequent stat ­
istical treatment aims at identifying which windows are suitable to assess 
the vehicle RDE performance.  
The ‘normality’ of the windows is conducted by comparing their CO  2 
distance-specific emissions (  1 ) with a reference curve. The test is complete 
when the test includes a sufficient number of normal windows, covering 
different speed areas (urban, rural, motorway).

3. MOVING AVERAGING WINDOWS  
3.1. Definition of averaging windows  
The instantaneous emissions calculated according to Appendix 4 shall be 
integrated using a moving averaging window method, based on the 
reference CO  2 mass. The principle of the calculation is as follows: The 
mass emissions are not calculated for the complete data set, but for sub- 
sets of the complete data set, the length of these sub-sets being 
determined so as to match the CO  2 mass emitted by the vehicle over 
the reference laboratory cycle. The moving average calculations are 
conducted with a time increment Δt corresponding to the data sampling 
frequency. These sub-sets used to average the emissions data are referred 
to as ‘averaging windows’.  ►M1 ►C1 The calculation described in the 
present point shall be run from the first point (forward). ◄ ◄ 
The following data shall not be considered for the calculation of the CO  2 
mass, the emissions and the distance of the averaging windows:  
— The periodic verification of the instruments and/or after the zero drift 
verifications;  
▼M1 
▼C1 __________  
▼B 
— Vehicle ground speed < 1 km/h;

The mass (or particle number) emissions  M gas,j shall be determined by 
integrating the instantaneous emissions in g/s (or #/s for PN) calculated as 
specified in Appendix 4.

in this annex;  
— The distance-specific CO  2 emissions  M CO2,d,j  ; 
— The average vehicle speed  v j

point of ignition on and include driving events during which no CO  2 is 
emitted.

4. EVALUATION OF WINDOWS  
4.1. Introduction  
The reference dynamic conditions of the test vehicle are set out from the 
vehicle CO  2 emissions versus average speed measured at type approval 
and referred to as ‘vehicle CO  2 characteristic curve’.  
To obtain the distance-specific CO  2 emissions, the vehicle shall be tested 
on the chassis dynamometer by applying the vehicle road load settings as 
determined following the procedure prescribed in Annex 4 of the UNECE 
Global Technical Regulation No. 15 - Worldwide harmonized Light 
vehicles Test Procedure (ECE/TRANS/180/Add.15). The road loads 
shall not account for the mass added to the vehicle during the RDE 
test, e.g. the co-pilot and the PEMS equipment.  
4.2. CO  2 characteristic curve reference points  
The reference points  P 1, P 2 and P 3 required to define the curve shall be 
established as follows:  
4.2.1.  Point P  1 
v P1 ¼ 19 km=h (average speed of the Low Speed phase of the WLTP 
cycle)  
M CO  2;d;P 1 = Vehicle CO  2 emissions over the Low Speed phase of the 
WLTP cycle x 1,2 [g/km]  
4.2.2.  Point P  2 
4.2.3.  v P2 ¼ 56,6 km =h (average speed of the High Speed phase of the WLTP 
cycle)  
M CO  2;d;P 2 = Vehicle CO  2 emissions over the High Speed phase of the 
WLTP cycle x 1.1 [g/km]  
4.2.4.  Point P  3 
4.2.5.  v P3 ¼ 92,3 km =h (average speed of the Extra High Speed phase of the 
WLTP cycle)  
M CO  2;d;P 3 = Vehicle CO  2 emissions over the Extra High Speed phase of 
the WLTP cycle x 1,05 [g/km]  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 182  
4.3. CO  2 characteristic curve definition  
Using the reference points defined in section 4.2, the characteristic curve 
CO  2 emissions are calculated as a function of the average speed using 
two linear sections ( P 1 , P 2 ) and ( P 2 , P 3 ). The section ( P 2 , P 3 ) is limited to 
145 km/h on the vehicle speed axis. The characteristic curve is defined by 
equations as follows:  
For the section ( P 1 ,P 2 ): 
M CO  2;d;CC ðvÞ ¼ a 1 v þ b 1 
with:  a  1 ¼ ðM CO  2;d;P 2 Ä M CO  2;d;P 1 Þ=ðv P2 Ä v P1 Þ 
and: b  1 ¼ M CO  2;d;P 1 Ä a 1 v P1 
For the section ( P 2 ,P 3 ): 
M CO  2;d;C C ðvÞ ¼ a 2 v þ b 2 
with:  a  2 ¼ ðM CO  2;d;P 3 Ä M CO  2;d;P 2 Þ=ðv P 3 Ä v P 2 Þ 
and: b  2 ¼ M CO  2;d;P 2 Ä a 2 v P2

smaller than 45 km/h,  
4.4.2. Rural windows are characterized by average vehicle ground speeds  v j 
greater than or equal to 45 km/h and smaller than 80 km/h,

5. VERIFICATION OF TRIP COMPLETENESS AND NORMALITY  
▼M1 
▼C1 
For N2 category vehicles that are equipped in accordance with Directive 
92/6/EEC with a device limiting vehicle speed to 90 km/h, the share of 
motorway windows in the complete test shall be at least 5 %.  
▼B 
5.1. Tolerances around the vehicle CO  2 characteristic curve  
The primary tolerance and the secondary tolerance of the vehicle CO  2 
characteristic curve are respectively  tol  1 = 25 % and  tol  2 = 50 %.  
5.2. Verification of test completeness  
The test shall be complete when it comprises at least 15 % of urban, rural 
and motorway windows, out of the total number of windows.  
5.3. Verification of test normality  
The test shall be normal when at least 50 % of the urban, rural and 
motorway windows are within the primary tolerance defined for the char ­
acteristic curve.  
If the specified minimum requirement of 50 % is not met, the upper 
positive tolerance  tol  1 may be increased by steps of 1 percentage point 
until the 50 % of normal windows target is reached. When using this 
approach,  tol  1 shall never exceed 30 %.  
▼M1 
▼C1 
When testing a NOVC-HEV and only if the specified minimum 
requirement of 50 % is not met, the upper positive tolerance  tol  1 may 
be increased by steps of 1 percentage point until the 50 % of normal 
windows target is reached. When using this approach,  tol  1 shall never 
exceed 50 %.  ▼B

7.3. Urban, rural and motorway windows - Trip completeness  
In this numerical example, the trip consists of 7 036 averaging windows. 
Table 5 lists the number of windows classified in urban, rural and 
motorway according to their average vehicle speed and divided in 
regions with respect to their distance to the CO  2 characteristic curve. 
The trip is complete since it comprises at least 15 % of urban, rural 
and motorway windows out of the total number of windows. In 
addition the trip is characterized as normal since at least 50 % of the 
urban, rural and motorway windows are within the primary tolerances 
defined for the characteristic curve.

3. EVALUATION OF THE MEASURED EMISSIONS USING A STAN ­
DARDISED WHEEL POWER FREQUENCY DISTRIBUTION  
The power binning method uses the instantaneous emissions of the pollu ­
tants, m  gas, i (g/s) calculated in accordance with Appendix 4.  
The m  gas, i values shall be classified in accordance with the corresponding 
power at the wheels and the classified average emissions per power class 
shall be weighted to obtain the emission values for a test with a normal 
power distribution according to the following points.  
3.1. Sources for the actual wheel power  
The actual wheel power P  r,i shall be the total power to overcome air 
resistance, rolling resistance, road gradients, longitudinal inertia of the 
vehicle and rotational inertia of the wheels.  
When measured and recorded, the wheel power signal shall use a torque 
signal meeting the linearity requirements laid down in Appendix 2, 
point 3.2. The reference point for measurement are the wheel hubs of 
the driven wheels.  
As an alternative, the actual wheel power may be determined from the 
instantaneous CO  2 emissions following the procedure laid down in 
point 4 of this Appendix.  
▼M1 
The provisions of this Appendix 6 shall only be applicable for 
NOVC-HEVs (as defined in point 1.2.40) if the power at the wheels 
has been determined by wheel hub torque measurements.  
3.2. Calculation of the moving averages of the instantaneous test data  
Three second moving averages shall be calculated from all relevant 
instantaneous test data to reduce influences of possibly imperfect time 
alignment between emission mass flow and wheel power. The moving 
average values shall be computed in a 1 Hz frequency:  
m gas;3s;k ¼ P kþ2 
i¼k m gas;i 
3 
P w;3s;k ¼ P kþ2 
i¼k P w;i

ν 3s;k ¼ P kþ2

3.3. Classification of the moving averages to urban, rural and motorway  
The standard power frequencies are defined for urban driving and for the 
total trip (see paragraph 3.4) and a separate evaluation of the emissions 
shall be made for the total trip and for the urban part. For the later 
evaluation of the urban part of the trip, the three second moving 
averages calculated according to paragraph 3.2 shall be allocated to 
urban driving conditions according to the three second moving average 
of the velocity signal (v  3s,k ) following the speed range defined in Table 1- 
1. The sample for the total trip evaluation shall cover all speed ranges 
including also the urban part.

3.5. Classification of the moving average values  
▼M1 __________  
▼B 
Each moving average value calculated according to point 3.2 shall be 
sorted into the de-normalized wheel power class into which the actual 3 
second moving average wheel power P  w , 3s,k fits. The de-normalised 
wheel power class limits have to be calculated according to point 3.3.  
The classification shall be done for all three second moving averages of 
the entire valid trip data including also all urban trip parts. Additionally 
all moving averages classified to urban according to the velocity limits 
defined in table 1-1 shall be classified into one set of urban power classes 
independently of the time when the moving average appeared in the trip.  
Then the average of all three second moving average values within a 
wheel power class shall be calculated for each wheel power class per 
parameter. The equations are described below and shall be applied once 
for the urban data set and once for the total data set.  
Classification of the 3-second moving average values into power class j 
(j = 1 to 9):  
if P  C;j lower bound < P w;3s;k Ï P C;j upper bound  
then: class index for emissions and velocity = j  
The number of 3-second moving average values shall be counted for each 
power class:  
if P  C;j lower bound < P w;3s;k Ï P C;j upper bound  
then: counts  j = n + 1 (counts  j is counting the number of 3 second moving 
average emission values in a power class to check later the minimum 
coverage demands)  ▼M2
 02017R1151 — EN — 27.07.2017 — 001.003 — 197  
3.6. Check of power class coverage and of normality of power distribution  
For a valid test a sufficient number of measured emission values have to 
be allocated to the relevant power classes. This demand is checked by the 
number of 3 second average values (counts) allocated to each power 
class:  
— a minimum coverage of 5 counts is demanded for the total trip in each

of the rated power whatever gives the lower class number. If the 
counts in a wheel power class above number 6 are less than 5, the 
average class emission value (m  gas,3s,k  ) and the average class velocity 
(v 3s,k ) shall be set to zero.  
— a minimum coverage of 5 counts is required for the urban part of the 
trip in each wheel power class up to class No 5 or up to the class 
containing 90 % of the rated power whatever gives the lower class 
number. If the counts in the urban part of the trip in a wheel power 
class above number 5 are less than 5, the average class emission value 
(m gas,3s,k  ) and the average class velocity (v  3s,k ) shall be set to zero.  
▼B 
3.7. Averaging of the measured values per wheel power class  
The moving averages sorted in each wheel power class shall be averaged 
as follows:  
m gas;j ¼ P 
all k in class  j m gas;3s;k 
counts  j 
v j ¼ P 
all k in class  j v 3s;k 
counts  j 
Where  
j wheel power class 1 to 9 according to Table 1  
m gas;j average emission value of an exhaust gas component in a wheel 
power class (separate value for total trip data and for the urban 
parts of the trip), [g/s]  
v j average velocity in a wheel power class (separate value for total 
trip data and for the urban parts of the trip), [km/h]  
k time step for moving average values  
3.8. Weighting of the average values per wheel power class  
The average values of each wheel power class shall be multiplied with the 
time share, t  C,j per class according to Table 1 and summed up to produce 
the weighted average value for each parameter. This value represents the 
weighted result for a trip with the standardised power frequencies. The 
weighted averages shall be computed for the urban part of the test data 
using the time shares for urban power distribution as well as for the total 
trip using the time shares for the total.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 198  
The equations are described below and shall be applied once for the 
urban data set and once for the total data set.  
m gas ¼ X  9 
j¼1 m gas;j Ü t c;j 
v ¼ X  9 
j¼1 v j Ü t c;j 
3.9 Calculation of the weighted distance-specific emission value  
The time based weighted averages of the emissions in the test shall be 
converted into distance based emissions once for the urban data set and 
once for the total data set as follows:  
For the total trip:  
M w;gas;d ¼ m gas Ü 3 600  
v 
For the urban part of the trip:  
M w;gas;d;U ¼ m gas;U Ü 3 600

For particle number the same method as for gaseous pollutants shall be 
applied but the unit [#/s] shall be used for  m PN and [#/km] shall be used 
for M  w,PN : 
For the total trip:  
M w;PN;d ¼ m PN Ü 3 600

For the urban part of the trip:  
M w;PN;d;U ¼ m PN Ü 3 600

4. ASSESSMENT OF THE WHEEL POWER FROM THE INSTAN ­
TANEOUS CO  2 MASS FLOW  
The power at the wheels (P  w,i ) can be computed from the measured CO  2 
mass flow in 1 Hz. For this calculation the vehicle specific CO  2 line 
(‘Veline’) shall be used.  
The Veline shall be calculated from the vehicle type approval test in the 
WLTC according to the test procedure described in UNECE Global 
Technical Regulation No. 15 - Worldwide harmonized Light vehicles 
Test Procedure (ECE/TRANS/180/Add.15).  
The average wheel power per WLTC phase shall be calculated in 1 Hz 
from the driven velocity and from the chassis dynamometer settings. For 
all wheel power values below the drag power shall be set to the drag 
power value.

Then a linear regression shall be made with the CO  2 mass flow from the 
bag values of the WLTC on the y-axis and from the average wheel power  
P w,p per phase on the x-axis as illustrated in Figure 2.  
The resulting Veline equation defines the CO  2 mass flow as function of 
the wheel power:

The actual wheel power shall be calculated from the measured CO  2 mass 
flow as follows:  
P w;i ¼ CO  2 i Ä D WLTC

With CO  2 in [g/h]  
P w,j in [kW]  
The above equation can be used to provide P  Wi for the classification of 
the measured emissions as described in point 3 with following additional 
conditions in the calculation:  
(I) if v  i ≤ 1 km/h and if CO2  i ≤ D WLTC  then P w,i = 0 
(II) if v  i > 1 km/h and if CO2  i < 0,5 X D  WLTC  then P w,i = P  drag 
▼B 
In time steps where (I) and (II) are valid, condition (II) shall be applied.  ▼M1

Due to their particular characteristics, PEMS tests are not required to be 
performed for each ‘ vehicle type with regard to emissions and vehicle 
repair and maintenance information ’ as defined in Article 2(1) of this 
Regulation, which is called in the following  ‘vehicle emission type’ . 
Several vehicle emission types may be put together by the vehicle manu ­
facturer to form a ‘ PEMS test family ’ according to the requirements of 
point 3, which shall be validated according to the requirements of 
point 4.  
2. SYMBOLS, PARAMETERS AND UNITS

3. PEMS TEST FAMILY BUILDING  
A PEMS test family shall comprise finished vehicles with similar 
emission characteristics. Vehicle emission types may be included in a 
PEMS test family only as long as the completed vehicles within a PEMS 
test family are identical with respect to the characteristics in points 3.1 
and 3.2.

3.2.6. Engine volume  
The vehicle manufacturer shall specify a value V_eng_max (= maximum 
engine volume of all vehicles within the PEMS test family). The engine 
volumes of vehicles in the PEMS test family shall not deviate more than 
– 22 % from V_eng_max if V_eng_max ≥ 1 500 ccm and – 32 % from

3.2.11. Exhaust gas recirculation (with or without, internal/external, cooled/non- 
cooled, low/high pressure)  
3.3. Extension of a PEMS test family  
An existing PEMS test family may be extended by adding new vehicle 
emission types to it. The extended PEMS test family and its validation 
must also fulfil the requirements of points 3 and 4. This may in 
particular require the PEMS testing of additional vehicles to validate 
the extended PEMS test family according to point 4.  
3.4. Alternative PEMS test family  
As an alternative to the provisions of points 3.1 to 3.2 the vehicle 
manufacturer may define a PEMS test family, which is identical to a 
single vehicle emission type. In this the requirement of point 4.1.2 for 
validating the PEMS test family shall not apply.  
4. VALIDATION OF A PEMS TEST FAMILY  
4.1. General requirements for validating a PEMS test family  
4.1.1. The vehicle manufacturer presents a representative vehicle of the PEMS 
test family to the authority. The vehicle shall be subject to a PEMS test 
carried out by a Technical Service to demonstrate compliance of the 
representative vehicle with the requirements of this Annex.  
4.1.2. The authority selects additional vehicles according to the requirements of 
point 4.2 of this Appendix for PEMS testing carried out by a Technical 
Service to demonstrate compliance of the selected vehicles with the 
requirements of this Annex. The technical criteria for selection of an 
additional vehicle according to point 4.2 of this Appendix. shall be 
recorded with the test results.  
4.1.3. With agreement of the authority, a PEMS test can also be driven by a 
different operator witnessed by a Technical Service, provided that at 
least the tests of the vehicles required by points 4.2.2 and 4.2.6 of 
this Appendix and in total at least 50 % of the PEMS tests required 
by this Appendix for validating the PEMS test family are driven by a 
Technical Service. In such case the Technical Service remains 
responsible for the proper execution of all PEMS tests pursuant to the 
requirements of this Annex.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 203  
4.1.4. A PEMS test results of a specific vehicle may be used for validating 
different PEMS test families according to the requirements of this 
Appendix under the following conditions:  
— the vehicles included in all PEMS test families to be validated are 
approved by a single authority according to the requirements of 
Regulation (EC) 715/2007 and this authority agrees to the use of 
the specific vehicle's PEMS test results for validating different PEMS 
test families;  
— each PEMS test family to be validated includes a vehicle emission 
type, which comprises the specific vehicle;  
For each validation the applicable responsibilities are considered to be 
borne by the manufacturer of the vehicles in the respective family, 
regardless of whether this manufacturer was involved in the PEMS 
test of the specific vehicle emission type.  
4.2. Selection of vehicles for PEMS testing when validating a PEMS test 
family  
By selecting vehicles from a PEMS test family it should be ensured that 
the following technical characteristics relevant for pollutant emissions 
are covered by a PEMS test. One vehicle selected for testing can be 
representative for different technical characteristics. For the validation of 
a PEMS test family vehicles shall be selected for PEMS testing as 
follows:  
4.2.1. For each combination of fuels (e.g. petrol-LPG, petrol-NG, petrol only), 
on which some vehicle of the PEMS test family can operate, at least one 
vehicle that can operate on this combination of fuels shall be selected for 
PEMS testing.  
4.2.2. The manufacturer shall specify a value PMR  H (= highest power-to-mass- 
ratio of all vehicles in the PEMS test family) and a value PMR  L (= 
lowest power-to-mass-ratio of all vehicles in the PEMS test family). 
Here the ‘power-to-mass-ratio’ corresponds to the ratio of the 
maximum net power of the internal combustion engine as indicated in 
point 3.2.1.8 of Appendix 3 to Annex I of this Regulation and of the 
reference mass as defined in Article 3(3) of Regulation (EC) No 
715/2007. At least one vehicle configuration representative for the 
specified PMR  H and one vehicle configuration representative for the 
specified PMR  L of a PEMS test family shall be selected for testing. If 
the power-to-mass ratio of a vehicle deviates by not more than 5 % from 
the specified value for PMR  H , or PMR  L , the vehicle should be 
considered as representative for this value.  
4.2.3. At least one vehicle for each transmission type (e.g., manual, automatic, 
DCT) installed in vehicles of the PEMS test family shall be selected for 
testing.  
4.2.4. At least one four-wheel drive vehicle (4x4 vehicle) shall be selected for 
testing if such vehicles are part of the PEMS test family.  
4.2.5. For each engine volume occurring on a vehicle in the PEMS family at 
least one representative vehicle shall be tested.  
4.2.6. At least one vehicle for each number of installed exhaust after-treatment 
components shall be selected for testing.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 204  
4.2.7. At least one vehicle in the PEMS family shall be tested in hot start 
testing.  
4.2.8. Notwithstanding the provisions in points 4.2.1 to 4.2.6, at least the 
following number of vehicle emission types of a given PEMS test 
family shall be selected for testing:  
Number N of vehicle emission 
types in a PEMS test family  Minimum number NT of vehicle emission types 
selected for PEMS cold start testing  Minimum number NT of vehicle 
emission types selected for PEMS 
hot start testing  
1 1  1 (  2 ) 
From 2 to 4  2  1  
from 5 to 7  3  1  
from 8 to 10  4  1  
from 11 to 49  NT = 3 + 0,1 x N (  1 ) 2  
more than 49  NT = 0,15 x N (  1 ) 3  
( 1 ) NT shall be rounded to the next higher integer number. 
( 2 ) when there is only one vehicle emission type in a PEMS test family, it shall be tested in both hot and cold start 
conditions.  
▼B 
5. REPORTING  
5.1. The vehicle manufacturer provides a full description of the PEMS test 
family, which includes in particular the technical criteria described in 
point 3.2 and submits it to the authority.  
5.2. The manufacturer attributes a unique identification number of the format  
MS-OEM-X-Y  to the PEMS test family and communicates it to the auth ­
ority. Here  MS is the distinguishing number of the Member State issuing 
the EC type-approval (  1 ), OEM is the 3 character manufacturer,  X is a 
sequential number identifying the original PEMS test family and  Y is a 
counter for its extensions (starting with 0 for a PEMS test family not 
extended yet).

3. TRIP INDICATORS  
3.1. Calculations  
3.1.1.  Data pre-processing  
Dynamic parameters like acceleration,  ν · a pos or RPA shall be 
determined with a speed signal of an accuracy of 0,1 % for all speed 
values above 3 km/h and a sampling frequency of 1 Hz. This accuracy 
requirement is generally fulfilled by signals obtained from a wheel 
(rotational) speed sensor.  
The speed trace shall be checked for faulty or implausible sections. The 
vehicle speed trace of such sections is characterised by steps, jumps, 
terraced speed traces or missing values. Short faulty sections shall be 
corrected, for example by data interpolation or benchmarking against a 
secondary speed signal. Alternatively, short trips containing faulty 
sections could be excluded from the subsequent data analysis. In a 
second step the acceleration values shall be calculated and ranked in 
ascending order, as to determine the acceleration resolution  
a res ¼ ðminimum acceleration value > 0Þ. 
If a res Ï 0,01 m =s 2 , the vehicle speed measurement is sufficiently 
accurate.  
If 0,01 m =s 2< a res , data smoothing by using a T4253H Hanning filter 
shall be performed  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 207  
The T4235 Hanning filter performs the following calculations: The 
smoother starts with a running median of 4, which is centred by a 
running median of 2. The filter then re-smoothes these values by 
applying a running median of 5, a running median of 3, and hanning 
(running weighted averages). Residuals are computed by subtracting the 
smoothed series from the original series. This whole process is then 
repeated on the computed residuals. Finally, the smoothed final speed 
values are computed by summing up the smoothed values obtained the 
first time through the process with the computed residuals.  
The correct speed trace builds the basis for further calculations and 
binning as described in paragraph 8.1.2.  
3.1.2.  Calculation of distance, acceleration and  ν · a 
The following calculations shall be performed over the whole time based 
speed trace (1 Hz resolution) from second 1 to second  t t (last second).  
The distance increment per data sample shall be calculated as follows:  
▼C2 
d i ¼ v i 
3,6; i ¼ 1 to N  t 
▼B 
where:  
d i is the distance covered in time step i [m]  
ν i is the actual vehicle speed in time step i [km/h]  
N t is the total number of samples  
The acceleration shall be calculated as follows:  
a i ¼ ðv iþ1 Ä v iÄ1 Þ=ð2 · 3,6Þ; i ¼ 1 to N  t 
where:  
a i is the acceleration in time step i [m/s  2 ]. For  i = 1:  v iÄ1 ¼ 0, for i ¼ N t : 
v iþ1 ¼ 0. 
The product of vehicle speed per acceleration shall be calculated as 
follows: 
ðv · aÞ i ¼ v i · a i=3,6; i ¼ 1 to N  t 
where: 
ðν · aÞ i is the product of the actual vehicle speed per acceleration in time 
step i [m  2 /s 3 or W/kg].  
3.1.3.  Binning of the results  
After the calculation of  a i and ðν · aÞ i , the values  v i , d i , a i and ðν · aÞ i 
shall be ranked in ascending order of the vehicle speed.  
All datasets with  v i Ï 60 km =h belong to the ‘urban’ speed bin, all 
datasets with  60 km =h< v i Ï 90 km =h belong to the ‘rural’ speed bin 
and all datasets with  v i> 90 km =h belong to the ‘motorway’ speed bin.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 208  
The number of datasets with acceleration values  a i> 0,1 m =s 2 shall be 
bigger or equal to 150 in each speed bin.  
For each speed bin the average vehicle speed  v k shall be calculated as 
follows:  
v k ¼ Ê X  
i v i;k Ì
=N k; i ¼ 1 to N  k; k ¼ u; r; m 
where:  
N k is the total number of samples of the urban, rural, and motorway 
shares.  
3.1.4.  Calculation of  v · a posÄ ½95â per speed bin  
The 95  th percentile of the  v · a pos values shall be calculated as follows:  
The ðv · aÞ i;k values in each speed bin shall be ranked in ascending order 
for all datasets with  a i;k> 0,1 m =s 2 a i;k ã 0,1 m =s 2 and the total 
number of these samples  M k shall be determined.  
Percentile values are then assigned to the  ðv · a pos Þ i;k values with  
a i;k ã 0,1 m =s 2 as follows:  
The lowest  v · a pos value gets the percentile 1/ M k , the second lowest 
2/M k , the third lowest 3/ M k and the highest value  M k=M k ¼ 100% : 
ðv · a pos Þ k Ä ½95â is the ðv · a pos Þ j;k value, with  j=M k ¼ 95% : If 
j=M k ¼ 95% : cannot be met, ðv · a pos Þ k Ä ½95â shall be calculated by 
linear interpolation between consecutive samples j and j+1 with  
j=M k< 95%  and ðj þ 1Þ=M k> 95% . 
The relative positive acceleration per speed bin shall be calculated as 
follows:  
RPA  k ¼ X  
j ðΔt · ðv · a pos Þ j;k Þ= X  
i d i;k; j ¼ 1 to M  k; i ¼ 1 to N  k; k ¼ u; r; m 
where:  
RPA  k is the relative positive acceleration for urban, rural and motorway 
shares in [m/s  2 or kWs/(kg*km)]  
Δ t is a time difference equal to 1 second  
M k is the sample number for urban, rural and motorway shares with 
positive acceleration  
N k is the total sample number for urban, rural and motorway shares

time t [s] that has passed since test start.

4.1. General  
The cumulative positive elevation gain of a RDE trip shall be calculated 
as a three-step procedure, consisting of (i) the screening and principle 
verification of data quality, (ii) the correction of instantaneous vehicle 
altitude data, and (iii) the calculation of the cumulative positive 
elevation gain.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 212  
4.2. Screening and principle verification of data quality  
The instantaneous vehicle speed data shall be checked for completeness. 
Correcting for missing data is permitted if gaps remain within the 
requirements specified in Point 7 of Appendix 4; else, the test results 
shall be voided. The instantaneous altitude data shall be checked for 
completeness. Data gaps shall be completed by data interpolation. The 
correctness of interpolated data shall be verified by a topographic map. It 
is recommended to correct interpolated data if the following condition 
applies: 
jh GPS ðtÞ Ä h map ðtÞj> 40m 
The altitude correction shall be applied so that:

where:

The altitude  h(0)  at the start of a trip at  d(0)  shall be obtained by GPS 
and verified for correctness with information from a topographic map. 
The deviation shall not be larger than 40 m. Any instantaneous altitude 
data h(t) shall be corrected if the following condition applies:  
jhðtÞ Ä hðt Ä 1Þj> ðvðtÞ=3,6 Ü sin45°Þ 
The altitude correction shall be applied so that:  
h corr ðtÞ ¼ h corr ðt Ä 1Þ 
where:  
h(t) —  vehicle altitude after the screening and principle verifi ­
cation of data quality at data point t [m above sea level]

cation of data quality at data point t-1 [m above sea level]

 02017R1151 — EN — 27.07.2017 — 001.003 — 213  
Upon the completion of the correction procedure, a valid set of altitude 
data is established. This data set shall be used for the calculation of the 
cumulative positive elevation gain as described in Point 13.4.  
4.4. Final calculation of the cumulative positive elevation gain  
4.4.1.  Establishment of a uniform spatial resolution  
The total distance  d tot [m] covered by a trip shall be determined as sum of 
the instantaneous distances  d i . The instantaneous distance  d i shall be 
determined as:  
d i ¼ v i 
3,6 
Where:  
d i — instantaneous distance [m]  
v i — instantaneous vehicle speed [km/h]  
The cumulative elevation gain shall be calculated from data of a constant 
spatial resolution of 1 m starting with the first measurement at the start of 
a trip  d(0) . The discrete data points at a resolution of 1 m are referred to 
as way points, characterized by a specific distance value d (e.g., 0, 1, 2, 3 
m…) and their corresponding altitude  h(d)  [m above sea level].  
The altitude of each discrete way point  d shall be calculated through 
interpolation of the instantaneous altitude  h corr (t) as: 
h int ðdÞ ¼ h corr ð0Þ þ h corr ð1Þ Ä h corr ð0Þ 
d 1 Ä d 0 Ü ðd Ä d 0 Þ 
Where:  
h int (d) —  interpolated altitude at the discrete way point under con ­
sideration  d [m above sea level]

[m above sea level]

[m above sea level]

under consideration  d [m]

directly before the respective way point  d [m]

directly after the respective way point  d [m]

by applying a two-step procedure;  d a and d e denote the first and last data 
point respectively (Figure 1). The first smoothing run shall be applied as 
follows:

signals
  
4.4.3.  Calculation of the final result  
The positive cumulative elevation gain of a trip shall be calculated by 
integrating all positive interpolated and smoothed road grades, i.e.  
road  grade,2  (d). The result should be normalized by the total test distance  
d tot and expressed in meters of cumulative elevation gain per one hundred 
kilometers of distance.  
5. NUMERICAL EXAMPLE  
Tables 1 and 2 show how to calculate the positive elevation gain on the 
basis of data recorded during an on-road test performed with PEMS. For 
the sake of brevity an extract of 800m and 160s is presented here.  
5.1. Screening and principle verification of data quality  
The screening and principle verification of data quality consists of two 
steps. First, the completeness of vehicle speed data is checked. No data 
gaps related to vehicle speed are detected in the present data sample (see 
Table 1). Second, the altitude data are checked for completeness; in the 
data sample, altitude data related to seconds 2 and 3 are missing. The 
gaps are filled by interpolating the GPS signal. In addition, the GPS 
altitude is verified by a topographic map; this verification includes the 
altitude  h(0)  at the start of the trip. Altitude data related to seconds 112 
-114 are corrected on the basis of the topographic map to satisfy the 
following condition:  
h GPS ðtÞ Ä h map ðtÞ< Ä40m 
As result of the applied data verification, the data in the fifth column  h(t) 
are obtained.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 216  
5.2. Correction of instantaneous vehicle altitude data  
As a next step, the altitude data  h(t) of seconds 1 to 4, 111 to 112 and 
159 to 160 are corrected assuming the altitude values of seconds 0, 110 
and 158 respectively since for the altitude data in these time periods the 
following condition applies:  
jhðtÞ Ä hðt Ä 1Þj> ðvðtÞ=3,6 Ü sin45°Þ 
As result of the applied data correction, the data in the sixth column  
h corr (t) are obtained. The effect of the applied verification and correction 
steps on the altitude data is depicted in Figure 2.  
5.3. Calculation of the cumulative positive elevation gain  
5.3.1.  Establishment of a uniform spatial resolution  
The instantaneous distance  d i is calculated by dividing the instantaneous 
vehicle speed measured in km/h by 3.6 (Column 7 in Table 1). Recalcu ­
lating the altitude data to obtain a uniform spatial resolution of 1 m yields 
the discrete way points d (Column 1 in Table 2) and their corresponding 
altitude values  h int (d) (Column 7 in Table 2). The altitude of each discrete 
way point d is calculated through interpolation of the measured instan ­
taneous altitude  h corr as: 
h int ð0Þ ¼ 120,3 þ 120,3 Ä 120,3 
0,1 Ä 0,0 Ü ð0 Ä 0Þ ¼ 120,3000  
h int ð520Þ ¼ 132,5 þ 132,6 Ä 132,5 
523,6 Ä 519,9 Ü ð520 Ä 519,9Þ ¼ 132,5027  
5.3.2.  Additional data smoothing  
In Table 2, the first and last discrete way points are:  d a =0m and  d e =799m, 
respectively. The altitude data of each discrete way point is smoothed by 
applying a two steps procedure. The first smoothing run consists of:  
road  grade ;1 ð0Þ ¼ h int ð200mÞ Ä h int ð0Þ 
ð0 þ 200mÞ ¼ 120,9682 Ä 120,3000 
200 ¼ 0,0033  
chosen to demonstrate the smoothing for d ≤ 200m 
road  grade ;1 ð320Þ ¼ h int ð520Þ Ä h int ð120Þ 
ð520Þ Ä ð120Þ ¼ 132,5027 Ä 121,0 
400 ¼ 0,0288  
chosen to demonstrate the smoothing for 200m < d < (599m) 
road  grade ;1 ð720Þ ¼ h int ð799Þ Ä h int ð520Þ 
799 Ä ð520Þ ¼ 121,2000 Ä 132,5027 
279 ¼ Ä0,0405  
chosen to demonstrate the smoothing for d ≥ (599m)  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 217  
The smoothed and interpolated altitude is calculated as:  
h int;sm;1 ð0Þ ¼ h int ð0Þ þ road  grade ;1 ð0Þ ¼ 120,3 þ 0,0033 Ô 120,3033 m 
h int;sm;1 ð799Þ ¼ h int;sm;1 ð798Þ þ road  grade ;1 ð799Þ ¼ 121,2550 Ä 0,0220 ¼ 121,2330 m 
Second smoothing run:  
road  grade ;2 ð0Þ ¼ h int;sm;1 ð200Þ Ä h int;sm;1 ð0Þ 
ð200Þ ¼ 119,9618 Ä 120,3033 
ð200Þ ¼ Ä0,0017  
chosen to demonstrate the smoothing for d ≤ 200m 
road  grade ;2 ð320Þ ¼ h int;sm;1 ð520Þ Ä h int;sm;1 ð120Þ 
ð520Þ Ä ð120Þ ¼ 123,6809 Ä 120,1843 
400 ¼ 0,0087  
chosen to demonstrate the smoothing for 200m < d < (599) 
road  grade ;2 ð720Þ ¼ h int;sm;1 ð799Þ Ä h int;sm;1 ð520Þ 
799 Ä ð520Þ ¼ 121,2330 Ä 123,6809 
279 ¼ Ä0,0088  
chosen to demonstrate the smoothing for d ≥ (599m)  
5.3.3.  Calculation of the final result  
The positive cumulative elevation gain of a trip is calculated by inte ­
grating all positive interpolated and smoothed road grades, i.e. values 
in the column  road  grade,2  (d) in Table 2. For the entire data set the total 
covered distance was  d tot ¼ 139,7 km  and all positive interpolated and 
smoothed road grades were of 516m. Therefore the positive cumulative 
elevation gain reached 516*100/139,7=370m/100km.

Appendix 7c  
Verification of trip conditions and calculation of the final RDE emissions 
result for OVC-HEVs  
1. INTRODUCTION  
This Appendix describes the verification of trip conditions and the calculation 
of the final RDE emissions result for OVC-HEVs. The method proposed in 
the Appendix will undergo review in order to find a more complete one.  
2. SYMBOLS, PARAMETERS AND UNITS  
M t is the weighted distance specific mass of gaseous pollutants 
[mg/km] or particle number [#/km], respectively emitted over 
the complete trip  
m t is the mass of gaseous pollutant [g] or particle number [#] 
emissions, respectively emitted over the complete trip  
m t,CO2 is the mass of CO  2 [g] emitted over the complete trip  
M u is the weighted distance-specific mass of gaseous pollutants 
[mg/km] or particle number [#/km], respectively emitted over 
the urban part of the trip  
m u is the mass of gaseous pollutant or the particle number emissions, 
respectively emitted over the urban part of the trip [mg]  
m u,CO2  is the mass of CO  2 [g] emitted over the urban part of the trip  
M WLTC,CO2  is the distance specific mass of CO  2 [g/km] for a test in charge 
sustaining mode over the WLTC  
3. GENERAL REQUIREMENTS  
The gaseous and particle pollutant emissions of OVC-HEVs shall be 
evaluated in two steps. First, the trip conditions shall be evaluated in 
accordance with point 4. Second, the final RDE emissions result is calculated 
in accordance with point 5. It is recommended to start the trip in charge- 
sustaining battery status to ensure that the third requirement of point 4 is 
fulfilled. The battery shall not be charged externally during the trip.  
4. VERIFICATION OF TRIP CONDITIONS  
It shall be verified in a simple three-step procedure that:  
(1) the trip complies with the general requirements, boundary conditions, trip 
and operational requirements, and the specifications for lubricating oil, 
fuel and reagents defined in points 4 to 8 of this Annex IIIa;  
(2) the trip complies with the trip conditions defined in Appendices 7a and 7b 
of this Annex IIIa.  
(3) the combustion engine has been working for a minimum cumulative 
distance of 12 km under urban conditions.  ▼M1
 02017R1151 — EN — 27.07.2017 — 001.003 — 222  
If the at least one of the requirements is not fulfilled, the trip shall be declared 
invalid and repeated until the trip conditions are valid.  
5. CALCULATION OF THE FINAL RDE EMISSIONS RESULT  
For valid trips, the final RDE result is calculated based on a simple evaluation 
of the ratios between the cumulative gaseous and particle pollutant emissions 
and the cumulative CO  2 emissions in three steps:  
(1) Determine the total gaseous pollutant and particle number emissions 
[mg;#] for the complete trip as  m t and over the urban part of the trip 
as m u . 
(2) Determine the total mass of CO  2 [g] emitted over the complete RDE trip 
as m t,CO2 and over the urban part of the trip as  m u,CO2  . 
(3) Determine the distance-specific mass of CO  2 M WLTC,CO2  [g/km] in 
charge-sustaining mode for the individual vehicles (declared value for 
the individual vehicle) as described in the Regulation (EU) 2017/1151; 
Type I test, including cold start.  
(4) Calculate the final RDE emissions result as:  
M t ¼ m t 
m t;CO  2 · M WLTC ;CO  2 for the complete trip;  
M u ¼ m u 
m u;CO  2 · M WLTC ;CO  2 for the urban part of the trip.  ▼M1

 02017R1151 — EN — 27.07.2017 — 001.003 — 254  
Figure VI.2  
Canister bench aging procedure
  
5.1.1. Temperature conditioning test  
In a dedicated temperature chamber, the canister(s) is (are) cycled 
between temperatures from – 15 °C to 60 °C, with 30 min of 
stabilisation at – 15 °C and 60 °C. Each cycle shall last 210 min 
as in Figure 3. The temperature gradient shall be as close as possible 
to 1 °C/min. No forced air flow should pass through the canister(s).  
The cycle is repeated 50 times consecutively. In total, this operation 
will last 175 hours.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 255  
Figure VI.3  
Temperature conditioning cycle
  
5.1.2. Canister vibration conditioning test  
After the temperature aging procedure, the canister(s) is (are) shaken 
along the vertical axis with the canister(s) mounted as per its orien ­
tation in the vehicle with overall Grms (  1 ) > 1.5m/sec  2 with 
frequency of 30 ± 10 Hz. The test shall last 12 hours.  
5.1.3. Canister Fuel aging test  
5.1.3.1. Fuel Aging for 300 cycles  
5.1.3.1.1. After the temperature conditioning test and vibration test, the 
canister(s) is aged with a mixture of Type 1 E10 market fuel as 
specified in point 5.1.3.1.1.1 below and nitrogen or air with a 50 ± 
15 percent fuel vapour volume. The fuel vapour fill rate must be 
kept between 60 ± 20 g/h.  
The canister(s) is (are) loaded to the corresponding breakthrough. 
Breakthrough shall be considered as the point at which the cumu ­
lative quantity of hydrocarbons emitted is equal to 2 grams. As an 
alternative, the loading is deemed completed when the equivalent 
concentration level at the vent hole reaches 3 000 ppm.  
5.1.3.1.1.1 The E10 market fuel used for this test shall fulfil the same 
requirements as an E10 reference fuel for the following points:  
Density at 15 °C  
— Vapour Pressure (DVPE)  
— Distillation (evaporates only)  
— Hydrocarbon analysis (olefins, aromatics, benzene only)  
— Oxygen content  
— Ethanol content  ▼B 
( 1 ) Grms: The root mean square (rms) value of the vibration signal is calculated by 
squaring the magnitude of the signal at every point, finding the average 
(mean) value of the squared magnitude, then taking the square root of the 
average value. The resulting number is the Grms metric.
 02017R1151 — EN — 27.07.2017 — 001.003 — 256  
5.1.3.1.2. The canister(s) shall be purged according the procedure of paragraph 
5.1.3.8. of Annex 7 to UN/ECE Regulation No 83.  
The canister must be purged between 5 minutes to 1 hour maximum 
after loading.  
5.1.3.1.3. The steps of the procedure set out in points 5.1.3.1.1. and 5.1.3.1.2. 
shall be repeated 50 times, followed by a measurement of the 
Butane Working Capacity (BWC), meant as the ability of an 
activated carbon canister to absorb and desorb butane from dry air 
under specified conditions, in 5 butane cycles, as described in point 
5.1.3.1.4 below. The fuel vapour ageing will continue until 300 
cycles are reached. A measurement of the BWC in 5 butane 
cycles, as set out in point 5.1.3.1.4, will be made after the 300 
cycles.  
5.1.3.1.4. After 50 and 300 Fuel aging cycles, a measurement of BWC is 
performed. This measurement consists of loading the canister 
according to paragraph 5.1.6.3., of Annex 7 to UN/ECE Regulation 
No 83 until breakthrough. The BWC is recorded.  
Then, the canister(s) shall be purged according the procedure of 
paragraph 5.1.3.8. of Annex 7 to UN/ECE Regulation No 83.  
The canister must be purged between 5 minutes to 1 hour maximum 
after loading.  
The operation of butane loading is repeated 5 times. The BWC is 
recorded after each butane loading step. The BWC  50 is calculated as 
the average of the 5 BWC and recorded.  
In total, the canister(s) will be aged with 300 fuel aging cycles + 10 
butane cycles and considered to be stabilized.  
5.1.3.2. If the canister(s) is (are) provided by the Suppliers, the Manufac ­
turers shall inform in advance the Type Approval Authorities to 
allow them to witness any part of the aging in the Supplier’s facil ­
ities.  
5.1.3.3. The manufacturer shall provide to the Type Approval Authorities a 
test report including at least the following elements:

fixed to a rig, then soaked with E10 reference fuel for 20 weeks at 
40 °C +/– 2 °C. The orientation of the fuel storage system on the rig 
has to be similar to the original orientation on the vehicle.  
5.2.1. The tank is filled with fresh E10 reference fuel at a temperature of 
18 °C ± 8 °C. The tank is filled at 40 +/– 2 % of the nominal tank 
capacity. Then, the rig with the fuel system is placed in a specific 
and secure room with a controlled temperature of 40 °C +/– 2 °C 
for 3 weeks.  
5.2.2. At the end of the 3  rd week, the tank is drained and refilled with 
fresh E10 reference fuel at a temperature of 18 °C ± 8 °C at 40 +/– 
2 % of the nominal tank capacity.  
Within 6 to 36 hours, the last 6h at 20 °C ± 2 °C the rig with the 
fuel system is placed in a VT-SHED a diurnal procedure is 
performed over a period of 24 hours, according to the procedure 
described according to paragraph 5.7. of Annex 7 of UN/ECE Regu ­
lation No 83. The fuel system is vented to the outside of the VT- 
SHED to eliminate the possibility of the tank venting emissions 
being counted as permeation. The HC emissions are measured and 
the value is recorded as HC  3W . ▼B

than the total load of VL at 80 km/h + 5 %, then the VH road load shall be 
used. VL and VH are defined in point 4.2.1.2 of Sub-Annex 4 to Annex 
XXI. Alternatively the manufacturer may choose to use road loads that have 
been determined according to the provisions of Appendix 7 of Annex 4a of 
UN/ECE Regulation No 83 for a vehicle included in the interpolation

3. IN-USE PERFORMANCE  
3.1. General Requirements  
The technical requirements and specifications shall be those set out in 
Appendix 1 to Annex 11 to UN/ECE Regulation No 83 with the 
exceptions and additional requirements as described in the following 
sections.  
3.1.1. The requirements of paragraph 7.1.5 of Appendix 1 to Annex 11 to 
UN/ECE Regulation No 83 shall be understood as being as follows.  
For new type approvals and new vehicles the monitor required by point 
2.9 of this Annex shall have an IUPR greater or equal to 0,1 until three 
years after the dates specified in Article 10(4) and (5) of Regulation 
(EC) No 715/2007 respectively.  
3.1.2. The requirements of paragraph 7.1.7 of Appendix 1 to Annex 11 to 
UN/ECE Regulation No 83 shall be understood as being as follows.  
The manufacturer shall demonstrate to the approval authority and, upon 
request, to the Commission that these statistical conditions are satisfied 
for all monitors required to be reported by the OBD system according 
to paragraph 7.6. of Appendix 1 to Annex 11 to Regulation No 83 not 
later than 18 months after the entry onto the market of the first vehicle 
type with IUPR in an OBD family and every 18 months thereafter. For 
this purpose, for OBD families consisting of more than 1000 regis ­
trations in the Union, that are subject to sampling within the 
sampling period, the process described in Annex II shall be used 
without prejudice to the provisions of paragraph 7.1.9. of Appendix 1 
to Annex 11 to Regulation No 83.  
In addition to the requirements set out in Annex II and regardless of the 
result of the audit described in Section 2 of Annex II, the authority 
granting the approval shall apply the in-service conformity check for 
IUPR described in Appendix 1 to Annex II in an appropriate number of 
randomly determined cases. ‘In an appropriate number of randomly 
determined cases’ means, that this measure has a dissuasive effect on 
non-compliance with the requirements of Section 3 of this Annex or the 
provision of manipulated, false or non-representative data for the audit. 
If no special circumstances apply and can be demonstrated by the type- 
approval authorities, random application of the in-service conformity 
check to 5 % of the type approved OBD families shall be considered 
as sufficient for compliance with this requirement. For this purpose, 
type-approval authorities may find arrangements with the manufacturer 
for the reduction of double testing of a given OBD family as long as 
these arrangements do not harm the dissuasive effect of the type- 
approval authority’s own in-service conformity check on non- 
compliance with the requirements of Section 3 of this Annex. Data 
collected by Member States during surveillance testing programmes  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 282  
may be used for in-service conformity checks. Upon request, type- 
approval authorities shall provide data on the audits and random in- 
service conformity checks performed, including the methodology used 
for identifying those cases, which are made subject to the random in- 
service conformity check, to the Commission and other type-approval 
authorities.  
3.1.3. Non-compliance with the requirements of paragraph 7.1.6. of Appendix 
1 to Annex 11 to Regulation No 83 established by tests described in 
point 3.1.2 of this Appendix or paragraph 7.1.9 of Appendix 1 to 
Annex 11 to Regulation No 83 shall be considered as an infringement 
subject to the penalties set out in Article 13 of Regulation (EC) No 
715/2007. This reference does not limit the application of such penalties 
to other infringements of other provisions of Regulation (EC) No 
715/2007 or this Regulation, which do not explicitly refer to Article 13 
of Regulation (EC) No 715/2007.  
3.1.4. Paragraph 7.6.1. of Appendix 1 to Annex 11 of UN/ECE Regulation 
No 83 shall be replaced with the following:  
‘7.6.1. The OBD system shall report, in accordance with the standard 
listed in paragraph 6.5.3.2.(a) of this Appendix, the ignition 
cycle counter and general denominator as well as separate 
numerators and denominators for the following monitors, if 
their presence on the vehicle is required by this annex:  
(a) Catalysts (each bank to be reported separately);  
(b) Oxygen/exhaust gas sensors, including secondary oxygen 
sensors  
(each sensor to be reported separately);  
(c) Evaporative system;  
(d) EGR system;  
(e) VVT system;  
(f) Secondary air system;  
(g) Particulate filter;  
(h) NOx after-treatment system (e.g. NOx absorber, NOx 
reagent/catalyst system);  
(i) Boost pressure control system.’  
Paragraph 7.6.2. of Appendix 1 to Annex 11 of UN/ECE Regulation 
No 83 shall be replaced with the following:  
‘7.6.2. For specific components or systems that have multiple 
monitors, which are required to be reported by this point 
(e.g. oxygen sensor bank 1 may have multiple monitors for 
sensor response or other sensor characteristics), the OBD 
system shall separately track numerators and denominators 
for each of the specific monitors and report only the  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 283  
corresponding numerator and denominator for the specific 
monitor that has the lowest numerical ratio. If two or more 
specific monitors have identical ratios, the corresponding 
numerator and denominator for the specific monitor that has 
the highest denominator shall be reported for the specific 
component.’  
A new paragraph 7.6.2.1. of Appendix 1 to Annex 11 of UN/ECE 
Regulation No 83 shall be inserted as follows:  
‘7.6.2.1. Numerators and denominators for specific monitors of 
components or systems, that are monitoring continuously for 
short circuit or open circuit failures are exempted from 
reporting.  
“Continuously,” if used in this context means monitoring is 
always enabled and sampling of the signal used for moni ­
toring occurs at a rate no less than two samples per second 
and the presence or the absence of the failure relevant to that 
monitor has to be concluded within 15 seconds.  
If for control purposes, a computer input component is 
sampled less frequently, the signal of the component may 
instead be evaluated each time sampling occurs.  
It is not required to activate an output component/system for 
the sole purpose of monitoring that output component/system.’  ▼B

‘ANNEX IX  
EC CERTIFICATE OF CONFORMITY  
0. OBJECTIVES  
The certificate of conformity is a statement delivered by the vehicle 
manufacturer to the buyer in order to assure him that the vehicle he has 
acquired complies with the legislation in force in the European Union 
at the time it was produced.  
The certificate of conformity also serves the purpose to enable the 
competent authorities of the Member States to register vehicles 
without having to require the applicant to supply additional technical 
documentation.  
For these purposes, the certificate of conformity has to include:  
(a) the Vehicle Identification Number;  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 331  
(b) the exact technical characteristics of the vehicle (i.e. it is not 
permitted to mention any range of value in the various entries).  
1. GENERAL DESCRIPTION  
1.1. The certificate of conformity shall consist of two parts.  
(a) SIDE 1, which consists of a statement of compliance by the manu ­
facturer. The same template is common to all vehicle categories.  
(b) SIDE 2, which is a technical description of the main characteristics 
of the vehicle. The template of side 2 is adapted to each specific 
vehicle category.  
1.2. The certificate of conformity shall be established in a maximum format 
A4 (210 × 297 mm) or a folder of maximum format A4.  
1.3. Without prejudice to the provisions in Section O(b), the values and 
units indicated in the second part shall be those given in the type- 
approval documentation of the relevant regulatory acts. In case of 
conformity of production checks the values shall be verified 
according to the methods laid down in the relevant regulatory acts. 
The tolerances allowed in those regulatory acts shall be taken into 
account.  
2. SPECIAL PROVISIONS  
2.1. Model A of the certificate of conformity (complete vehicle) shall cover 
vehicles which can be used on the road without requiring any further 
stage for their approval.  
2.2. Model B of the certificate of conformity (completed vehicles) shall 
cover vehicles which have undergone a further stage for their approval.  
This is the normal result of the multi-stage approval process (e.g. a bus 
built by a second stage manufacturer on a chassis built by a vehicle 
manufacturer).  
The additional features added during the multi-stage process shall be 
described briefly.  
2.3. Model C of the certificate of conformity (incomplete vehicles) shall 
cover vehicles which need a further stage for their approval (e.g. truck 
chassis).  
Except for tractors for semi-trailers, certificates of conformity covering 
chassis-cab vehicles belonging to category N shall be of Model C.

8. Cycle modification  
Paragraph 8. of this Sub-Annex shall not apply to OVC-HEVs, 
NOVC-HEVs and NOVC-FCHVs.  
8.1. General remarks  
The cycle to be driven shall depend on the test vehicle’s rated power 
to mass in running order ratio, W/kg, and its maximum velocity, 
v max , km/h.  
Driveability problems may occur for vehicles with power to mass 
ratios close to the borderlines between Class 1 and Class 2, Class 2 
and Class 3 vehicles, or very low powered vehicles in Class 1.  
Since these problems are related mainly to cycle phases with a 
combination of high vehicle speed and high accelerations rather 
than to the maximum speed of the cycle, the downscaling 
procedure shall be applied to improve driveability.  
8.2. This paragraph describes the method to modify the cycle profile using 
the downscaling procedure.  
8.2.1. Downscaling procedure for Class 1 vehicles  
Figure A1/14 shows a downscaled medium speed phase of the Class 1 
WLTC as an example.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 459  
Figure A1/14  
Downscaled medium speed phase of the class 1 WLTC
  
For the Class 1 cycle, the downscaling period is the time period 
between second 651 and second 906. Within this time period, the 
acceleration for the original cycle shall be calculated using the 
following equation: 
a orig  i ¼ v iþ1 Ä v i 
3,6 
where:  
v i is the vehicle speed, km/h;  
i is the time between second 651 and second 906.  
The downscaling shall be applied first in the time period between 
second 651 and second 848. The downscaled speed trace shall be 
subsequently calculated using the following equation: 
v dsc iþ1 ¼ v dsc i þ a orig  i Ü ð1 Ä f dsc Þ Ü 3,6 
with i = 651 to 847.  
For i = 651,  v dsc  i ¼ v orig  i 
In order to meet the original vehicle speed at second 907, a correction 
factor for the deceleration shall be calculated using the following 
equation: 
f corr_dec ¼ v dsc_848 Ä 36,7 
v orig_848 Ä 36,7  
where 36,7 km/h is the original vehicle speed at second 907.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 460  
The downscaled vehicle speed between second 849 and second 906 
shall be subsequently calculated using the following equation: 
v dsc i ¼ v dsc iÄ1 þ a orig  iÄ1 Ü f corr_dec Ü 3,6 
for i = 849 to 906.  
8.2.2. Downscaling procedure for Class 2 vehicles  
Since the driveability problems are exclusively related to the extra 
high speed phases of the Class 2 and Class 3 cycles, the downscaling 
is related to those paragraphs of the extra high speed phases where the 
driveability problems occur (see Figure A1/15).  
Figure A1/15  
Downscaled extra high speed phase of the class 2 WLTC
  
For the Class 2 cycle, the downscaling period is the time period 
between second 1520 and second 1742. Within this time period, the 
acceleration for the original cycle shall be calculated using the 
following equation: 
a orig  i ¼ v iþ1 Ä v i 
3,6 
where:  
v i is the vehicle speed, km/h;  
i is the time between second 1520 and second 1742.  
The downscaling shall be applied first to the time period between 
second 1520 and second 1725. Second 1725 is the time when the 
maximum speed of the extra high speed phase is reached. The down ­
scaled speed trace shall be subsequently calculated using the 
following equation: 
v dsc iþ1 ¼ v dsc i þ a orig  i Ü ð1 Ä f dsc Þ Ü 3,6 ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 461  
for i = 1520 to 1724.  
For i = 1520,  v dsc  i ¼ v orig  i 
In order to meet the original vehicle speed at second 1743, a 
correction factor for the deceleration shall be calculated using the 
following equation: 
f corr_dec ¼ v dsc_1725 Ä 90,4 
v orig_1725 Ä 90,4  
90,4 km/h is the original vehicle speed at second 1743.  
The downscaled vehicle speed between second 1726 and second 1742 
shall be calculated using the following equation: 
v dsc i ¼ v dsc iÄ1 þ a orig  iÄ1 Ü f corr_dec Ü 3,6 
for i = 1726 to 1742.  
8.2.3. Downscaling procedure for Class 3 vehicles  
Figure A1/16 shows a downscaled extra high speed phase of the Class 
3 WLTC as an example.  
Figure A1/16  
Downscaled extra high speed phase of the class 3 WLTC
  
For the Class 3 cycle, the downscaling period is the time period 
between second 1533 and second 1762. Within this time period, the 
acceleration for the original cycle shall be calculated using the 
following equation: 
a orig  i ¼ v iþ1 Ä v i 
3,6 ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 462  
where:  
v i is the vehicle speed, km/h;  
i is the time between second 1533 and second 1762.  
The downscaling shall be applied first in the time period between 
second 1533 and second 1724. Second 1724 is the time when the 
maximum speed of the extra high speed phase is reached. The down ­
scaled speed trace shall be subsequently calculated using the 
following equation: 
v dsc iþ1 ¼ v dsc i þ a orig  i Ü ð1 Ä f dsc Þ Ü 3,6 
for i = 1533 to 1723.  
For i = 1533,  v dsc  i ¼ v orig  i 
In order to meet the original vehicle speed at second 1763, a 
correction factor for the deceleration shall be calculated using the 
following equation: 
f corr_dec ¼ v dsc_1724 Ä 82,6 
v orig_1724 Ä 82,6  
82.6 km/h is the original vehicle speed at second 1763.  
The downscaled vehicle speed between second 1725 and second 1762 
shall be subsequently calculated using the following equation: 
v dsc i ¼ v dsc iÄ1 þ a orig  iÄ1 Ü f corr_dec Ü 3,6 
for i = 1725 to 1762.  
8.3. Determination of the downscaling factor  
The downscaling factor f  dsc , is a function of the ratio r  max between the 
maximum required power of the cycle phases where the downscaling 
is to be applied and the rated power of the vehicle, P  rated . 
The maximum required power P  req,max,i  (in kW) is related to a specific 
time i and the corresponding vehicle speed v  i in the cycle trace and is 
calculated using the following equation: 
P req;max;i ¼ Ê 
ðf 0 Ü v i Þ þ ðf 1 Ü v 2 
i Þ þ ðf 2 Ü v 3 
i Þ þ ð1,03 Ü TM Ü v i Ü a i Þ Ì 
3 600  
where:  
f 0 , f 1 , f 2 are the applicable road load coefficients, N, N/(km/h), and 
N/(km/h)  2 respectively;  
TM is the applicable test mass, kg;  
v i is the speed at time i, km/h.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 463  
The cycle time i at which maximum power or power values close to 
maximum power is required, is: second 764 for Class 1, second 1574 
for Class 2 and second 1566 for Class 3 vehicles.  
The corresponding vehicle speed values, v  i , and acceleration values, 
a i , are as follows:  
v i = 61,4 km/h, a  i = 0,22 m/s  2 for Class 1,  
v i = 109,9 km/h, a  i = 0,36 m/s  2 for Class 2,  
v i = 111,9 km/h, a  i = 0,50 m/s  2 for Class 3.  
r max shall be calculated using the following equation: 
r max ¼ P req;max;i 
P rated 
The downscaling factor, f  dsc , shall be calculated using the following 
equations:  
if r max< r 0 , then  f dsc ¼ 0 
and no downscaling shall be applied.  
If r max ã r 0 , then  f dsc ¼ a 1 Ü r max þ b 1 
The calculation parameter/coefficients, r  0 , a 1 and b  1 , are as follows:  
Class 1 r  0 = 0,978, a  1 = 0,680, b  1 = – 0,665  
Class 2 r  0 = 0,866, a  1 = 0,606, b  1 = – 0,525.  
Class 3 r  0 = 0,867, a  1 = 0,588 b  1 = – 0,510.  
The resulting f  dsc is mathematically rounded to 3 places of decimal 
and is applied only if it exceeds 0,010.  
The following data shall be included in all relevant test reports:  
(a) f  dsc ; 
(b) v  max ; 
(c) distance driven, m.  
The distance shall be calculated as the sum of v  i in km/h divided by 
3,6 over the whole cycle trace.  
8.4. Additional requirements  
For different vehicle configurations in terms of test mass and driving 
resistance coefficients, downscaling shall be applied individually.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 464  
If, after the application of downscaling the vehicle maximum speed is 
lower than the maximum speed of the cycle, the process described in 
paragraph 9. of this Sub-Annex shall be applied with the applicable 
cycle.  
If the vehicle cannot follow the speed trace of the applicable cycle 
within the tolerance at speeds lower than its maximum speed, it shall 
be driven with the accelerator control fully activated during these 
periods. During such periods of operation, speed trace violations 
shall be permitted.  
9. Cycle modifications for vehicles with a maximum speed lower than 
the maximum speed of the cycle specified in the previous paragraphs 
of this Sub-Annex  
9.1. General remarks  
This paragraph applies to vehicles that are technically able to follow 
the speed trace of the cycle specified in paragraph 1. of this Sub- 
Annex (base cycle or downscaled base cycle) at speeds lower than 
their maximum speed, but whose maximum speed is lower than the 
maximum speed of the cycle. The maximum speed of such a vehicle 
shall be referred to as its capped speed v  cap . The maximum speed of 
the base cycle shall be referred to as v  max,cycle  . 
In such cases the base cycle shall be modified as described in 
paragraph 9.2. in order to achieve the same cycle distance for the 
capped speed cycle as for the base cycle.  
9.2. Calculation steps  
9.2.1. Determination of the distance difference per cycle phase

manual transmissions  
1. General approach  
1.1. The shifting procedures described in this Sub-Annex shall apply to vehicles 
equipped with manual shift transmissions.  
1.2. The prescribed gears and shifting points are based on the balance between 
the power required to overcome driving resistance and acceleration, and the 
power provided by the engine in all possible gears at a specific cycle phase.  
1.3. The calculation to determine the gears to use shall be based on engine 
speeds and full load power curves versus engine speed.  
1.4. For vehicles equipped with a dual-range transmission (low and high), only 
the range designed for normal on-road operation shall be considered for 
gear use determination.  
1.5. The prescriptions for the clutch operation shall not be applied if the clutch 
is operated automatically without the need of an engagement or 
disengagement of the driver.  
1.6. This Sub-Annex shall not apply to vehicles tested according to 
Sub-Annex 8.  
2. Required data and precalculations  
The following data are required and calculations shall be performed in 
order to determine the gears to be used when driving the cycle on a 
chassis dynamometer:  
(a) P  rated , the maximum rated engine power as declared by the manufac ­
turer, kW;  
(b) n  rated , the rated engine speed at which an engine develops its maximum 
power. If the maximum power is developed over an engine speed 
range, n  rated shall be the minimum of this range, min  –1 ; 
(c) n  idle , idling speed, min  –1 ; 
n idle shall be measured over a period of at least 1 minute at a sampling 
rate of at least 1 Hz with the engine running in warm condition, the 
gear lever placed in neutral, and the clutch engaged. The conditions for 
temperature, peripheral and auxiliary devices, etc. shall be the same as 
described in Sub-Annex 6 for the Type 1 test.  
The value to be used in this Sub-Annex shall be the arithmetic average 
over the measuring period, rounded or truncated to the nearest 10 
min  –1 ; ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 469  
(d) ng, the number of forward gears;  
The forward gears in the transmission range designed for normal 
on-road operation shall be numbered in descending order of the ratio 
between engine speed in min  –1 and vehicle speed in km/h. Gear 1 is the 
gear with the highest ratio, gear ng is the gear with the lowest ratio. ng

reached, min  –1 ; 
If n  max_95  is less than 65 per cent of n  rated , n max_95  shall be set to 65 per 
cent of n  rated . 
If 65 per cent of  ðn rated Ü ndv  3=ndv  2 Þ< 1,1 Ü ðn idle þ 0,125Ü 
(n rated - n idle )), n  max_95  shall be set to:  
1,1 Ü ðn idle þ 0,125 Ü ðn rated Ä n idle ÞÞ Ü ndv  2=ndv  3 
n max ðng vmax Þ ¼ ndvðng vmax Þ Ü v max;cycle 
where:  
ng vmax is defined in paragraph 2(i) of this Sub-Annex.;  
v max,cycle  is the maximum speed of the vehicle speed trace according 
to Sub-Annex 1, km/h;  
n max is the maximum of n  max_95  and n  max (ng  vmax ), min  –1 . 
(h) P  wot (n), the full load power curve over the engine speed range from 
n idle to n  rated or n  max , or ndv(ng  vmax ) × v  max , whichever is higher.  
ndv(ng  vmax ) is the ratio obtained by dividing the engine speed n by the 
vehicle speed v for the gear ng  vmax , min  –1 /km/h;  
The power curve shall consist of a sufficient number of data sets (n, 
P wot ) so that the calculation of interim points between consecutive data 
sets can be performed by linear interpolation. Deviation of the linear 
interpolation from the full load power curve according to Annex XX 
shall not exceed 2 per cent. The first data set shall be at n  idle or lower. 
Data sets need not be spaced equally. The full load power at engine 
speeds not covered by Annex XX (e.g. n  idle ) shall be determined 
according to the method described in Annex XX.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 470  
(i) ng  vmax 
ng vmax , the gear in which the maximum vehicle speed is reached and 
shall be determined as follows:  
If v  max (ng) ≥ v max (ng-1), then,  
ng vmax = ng  
otherwise, ng  vmax = ng-1  
where:  
v max (ng) is the vehicle speed at which the required road load power 
equals the available power, P  wot , in gear ng (see Figure 
A2/1a).  
v max (ng-1) is the vehicle speed at which the required road load power 
equals the available power, P  wot , in the next lower gear 
(see Figure A2/1b).  
The required road load power, kW, shall be calculated using the 
following equation:  
P required ¼ f 0 Ü v max þ f 1 Ü v 2 
max þ f 2 Ü v 3 
max 
3 600  
where:  
v max is the vehicle speed, km/h.  
The available power at vehicle speed v  max in gear ng or gear ng - 1 
may be determined from the full load power curve, P  wot (n), by using 
the following equation:  
n ng ¼ ndv  ng Ü v max ðngÞ; n ngÄ1 ¼ ndv  ngÄ1 Ü v max ðng Ä 1Þ 
and by reducing the power values of the full load power curve by 10 
per cent.  ▼B

(2) The vehicle family is homologated to tow a trailer;  
(3) ðndv  1=ndvðng vmax ÞÞ Ü ðv max Ü ndvðng vmax Þ=n rated Þ> 7;

(5) The vehicle, having a mass as defined in the equation below, shall 
be able to pull away from standstill within 4 seconds, on an uphill 
gradient of at least 12 per cent, on five separate occasions within a 
period of 5 minutes.  
m r + 25 kg + (MC – m  r – 25 kg) × 0,28 (0,15 in the case of category 
M vehicles).  
where:  
ndv(ng  vmax ) is the ratio obtained by dividing the engine speed n by 
the vehicle speed v for gear ng  vmax , min  –1 /km/h;  
m r is the mass in running order, kg;  
MC is the gross train mass (gross vehicle mass + max. trailer 
mass), kg.  
In this case, gear 1 is not used when driving the cycle on a chassis 
dynamometer and the gears shall be renumbered starting with the 2  nd 
gear as gear 1.  
(k) Definition of n  min_drive  
n min_drive  is the minimum engine speed when the vehicle is in motion, 
min  –1 ; 
For n  gear = 1, n  min_drive  = n  idle , 
For n  gear = 2, 
(a) for transitions from 1  st to 2  nd gear:  
n min_drive  = 1,15 ×n  idle , 
(b) for decelerations to standstill:  
n min_drive  = n  idle . 
(c) for all other driving conditions:  
n min_drive  = 0,9 × n  idle . ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 473  
For n  gear > 2, n  min_drive  shall be determined by:  
n min_drive  = n  idle + 0,125 ×(n  rated -n idle ). 
The final result for n  min_drive  shall be rounded to the nearest integer. 
Example: 1 199,5 becomes 1 200, 1 199,4 becomes 1 199.  
Higher values may be used if requested by the manufacturer.  
(l) TM, test mass of the vehicle, kg.  
3. Calculations of required power, engine speeds, available power, and 
possible gear to be used  
3.1. Calculation of required power  
For each second j of the cycle trace, the power required to overcome 
driving resistance and to accelerate shall be calculated using the 
following equation: 
P required ;j ¼ Í f 0 Ü v j þ f 1 Ü v 2 
j þ f 2 Ü v 3 
j 
3 600 Î 
þ kr Ü a j Ü v j Ü TM 
3 600  
where:  
P required,j  is the required power at second j, kW;  
a j is the vehicle acceleration at second j, m/s  2 , a j ¼ ðv jþ1 Äv j Þ 
3,6Üðt jþ1 Ät j Þ ; 
kr is a factor taking the inertial resistances of the drivetrain during 
acceleration into account and is set to 1,03.  
3.2. Determination of engine speeds  
For any v  j < 1 km/h, it shall be assumed that the vehicle is standing still 
and the engine speed shall be set to.The gear lever shall be placed in 
neutral with the clutch engaged except 1 second before beginning an accel ­
eration from standstill where first gear shall be selected with the clutch 
disengaged.  
For each v  j ≥ 1 km/h of the cycle trace and each gear i, i = 1 to ng  max , the 
engine speed, n  i,j , shall be calculated using the following equation: 
n i;j ¼ ndv  i Ü v j 
3.3. Selection of possible gears with respect to engine speed  
The following gears may be selected for driving the speed trace at v  j : 
(a) all gears i < ng  vmax where n  min_drive  ≤ n i,j ≤ n max_95  , 
(b) all gears i ≥ ng  vmax where n  min_drive  ≤ n i,j ≤ n max (ng  vmax ) 
(c) gear 1, if n  1,j < n  min_drive  . ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 474  
If a  j ≤ 0 and n  i,j ≤ n idle , n i,j shall be set to n  idle and the clutch shall be 
disengaged.  
If a  j > 0 and n  i,j ≤ (1,15 × n  idle ), n  i,j shall be set to (1,15 × n  idle ) and the 
clutch shall be disengaged.  
3.4. Calculation of available power  
The available power for each possible gear i and each vehicle speed value 
of the cycle trace, shall be calculated using the following equation: 
P available_i ;j ¼ P wot ðn i;j Þ Ü ð1 Ä ðSM þ ASMÞÞ 
where:  
P rated is the rated power, kW;  
P wot is the power available at n  i,j at full load condition from the full load 
power curve;  
SM is a safety margin accounting for the difference between the 
stationary full load condition power curve and the power 
available during transition conditions. SM is set to 10 per cent;  
ASM is an additional exponential power safety margin, which may be 
applied at the request of the manufacturer. ASM is fully effective 
between n  idle and n  start , and approaches zero exponentially at n  end 
as described by the following requirements:  
If n  i,j ≤ n start , then ASM = ASM  0 ; 
If n  i,j > n  start , then: 
ASM ¼ ASM  0 Ü expðlnð0,005 =ASM  0 Þ Ü ðn start Ä nÞ=ðn start Ä n end ÞÞ 
ASM  0 , n start and n  end shall be defined by the manufacturer but shall fulfil 
the following conditions:  
n start ≥ n idle , 
n end > n  start . 
If a  j > 0 and i = 1 or i = 2 and P  available_i,i  < P  required,j  , n i,j shall be increased 
by increments of 1 min  –1 until P  available_i,i  = P  required,j  , and the clutch shall 
be disengaged.  
3.5. Determination of possible gears to be used  
The possible gears to be used shall be determined by the following 
conditions:  
(a) The conditions of paragraph 3.3. are fulfilled, and  
▼C2 
(b) P  available_i,j  ≥ P required,j  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 475  
The initial gear to be used for each second of the cycle trace is the highest 
final possible gear, i  max . When starting from standstill, only the first gear 
shall be used.  
The lowest final possible gear is i  min . 
4. Additional requirements for corrections and/or modifications of gear use  
The initial gear selection shall be checked and modified in order to avoid 
too frequent gearshifts and to ensure driveability and practicality.  
An acceleration phase is a time period of more than 3 seconds with a 
vehicle speed ≥ 1 km/h and with monotonic increase of vehicle speed. A 
deceleration phase is a time period of more than 3 seconds with a vehicle 
speed ≥ 1 km/h and with monotonic decrease of vehicle speed.  
Corrections and/or modifications shall be made according to the following 
requirements:  
(a) If a lower gear is required at a higher vehicle speed during an accel ­
eration phase, the higher gears before shall be corrected to the lower 
gear.  
Example:  v j < v  j+1 < v  j+2 < v  j+3 < v  j+4 < v  j+5 < v  j+6 . The original 
calculated gear use is 2, 3, 3, 3, 2, 2, 3. In this case the gear use shall 
be corrected to 2, 2, 2, 2, 2, 2, 3.  
(b) Gears used during accelerations shall be used for a period of at least 2 
seconds (e.g. a gear sequence 1, 2, 3, 3, 3, 3, 3 shall be replaced by 1, 
1, 2, 2, 3, 3, 3). Gears shall not be skipped during acceleration phases.  
(c) During a deceleration phase, gears with n  gear > 2 shall be used as long 
as the engine speed does not drop below n  min_drive  . 
If the duration of a gear sequence is only 1 second, it shall be replaced 
by gear 0 and the clutch shall be disengaged.  
If the duration of a gear sequence is 2 seconds, it shall be replaced by 
gear 0 for the 1  st second and for the 2  nd second with the gear that 
follows after the 2 second period. The clutch shall be disengaged for 
the 1  st second.  
Example : A gear sequence 5, 4, 4, 2 shall be replaced by 5, 0, 2, 2.  
(d) The 2  nd gear shall be used during a deceleration phase within a short 
trip of the cycle as long as the engine speed does not drop below (0.9 × 
n idle ). 
If the engine speed drops below n  idle , the clutch shall be disengaged.  
(e) If the deceleration phase is the last part of a short trip shortly before a 
stop phase and the 2  nd gear would only be used for up to two seconds, 
the clutch may be either disengaged or the gear lever placed in neutral 
and the clutch left engaged.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 476  
A downshift to first gear is not permitted during those deceleration 
phases.  
(f) If gear is used for a time sequence of 1 to 5 seconds and the gear prior 
to this sequence is lower and the gear after this sequence is the same as 
or lower than the gear before this sequence, the gear for the sequence 
shall be corrected to the gear before the sequence.  
Examples:  
(i) gear sequence i – 1, i, i – 1 shall be replaced by i – 1, i – 1,i – 1;  
(ii) gear sequence i – 1, i, i, i – 1 shall be replaced by i – 1, i – 1, 
i – 1, i – 1;  
(iii) gear sequence i – 1, i, i,i, i – 1 shall be replaced by i – 1, i – 1, 
i – 1, i – 1, i – 1;  
(iv) gear sequence i – 1, i, i, i, i, i – 1 shall be replaced by i – 1, i – 1,

the complete cycle trace in each case. Since modifications to paragraphs 
4.(a) to 4.(f) of this Sub-Annex may create new gear use sequences, these 
new gear sequences shall be checked three times and modified if necessary.  
In order to enable the assessment of the correctness of the calculation, the 
average gear for v ≥ 1 km/h, rounded to four places of decimal, shall be 
calculated and included in all relevant test reports.  ▼B

Sub-Annex 4  
Road load and dynamometer setting  
1. Scope  
This Sub-Annex describes the determination of the road load of a 
test vehicle and the transfer of that road load to a chassis dynamo ­
meter.  
2. Terms and definitions  
2.1. Reserved  
2.2. Reference speed points shall start at 20 km/h in incremental steps of 
10 km/h and with the highest reference speed according to the 
following provisions:  
(a) The highest reference speed point shall be 130 km/h or the 
reference speed point immediately above the maximum speed 
of the applicable test cycle if this value is less than 130 km/h. In 
the case that the applicable test cycle contains less than the 4 
cycle phases (Low, Medium, High and Extra High) and at the 
request of the manufacturer and with approval of the approval 
authority, the highest reference speed may be increased to the 
reference speed point immediately above the maximum speed of 
the next higher phase, but no higher than 130 km/h; in this case 
road load determination and chassis dynamometer setting shall 
be done with the same reference speed points;  
(b) If a reference speed point applicable for the cycle plus 14 km/h 
is more than or equal to the maximum vehicle speed v  max , this 
reference speed point shall be excluded from the coastdown test 
and from chassis dynamometer setting. The next lower reference 
speed point shall become the highest reference speed point for 
the vehicle.  
2.3. Unless otherwise specified, a cycle energy demand shall be 
calculated according to paragraph 5. of Sub-Annex 7 over the 
target speed trace of the applicable drive cycle.  
2.4. f  0 , f 1 , f 2 are the road load coefficients of the road load equation 
F = f  0 + f 1 × v + f  2 × v  2 , determined according to this Sub-Annex.  
f 0 is the constant road load coefficient, N;  
f 1 is the first order road load coefficient,, N/(km/h);  
f 2 is the second order road load coefficient, N/(km/h)  2 . 
Unless otherwise stated, the road load coefficients shall be 
calculated with a least square regression analysis over the range 
of the reference speed points.  ▼B

2.5. Rotational mass  
2.5.1. Determination of m  r 
m r is the equivalent effective mass of all the wheels and vehicle 
components rotating with the wheels on the road while the gearbox 
is placed in neutral, in kilograms (kg). m  r shall be measured or 
calculated using an appropriate technique agreed upon by the 
approval authority. Alternatively, m  r may be estimated to be 3 per 
cent of the sum of the mass in running order and 25 kg.  
2.5.2. Application of rotational mass to the road load  
Coastdown times shall be transferred to forces and vice versa by 
taking into account the applicable test mass plus m  r . This shall 
apply to measurements on the road as well as on a chassis dyna ­
mometer.  
2.5.3. Application of rotational mass for the inertia setting  
If the vehicle is tested on a 4 wheel drive dynamometer and if both 
axles are rotating and influencing the dynamometer measurement 
results, the equivalent inertia mass of the chassis dynamometer 
shall be set to the applicable test mass.  
Otherwise, the equivalent inertia mass of the chassis dynamometer 
shall be set to the test mass plus either the equivalent effective mass 
of the wheels not influencing the measurement results or 50 per cent 
of m  r . 
3. General requirements

load coefficients and will ensure this for each production vehicle 
within the road load family. Tolerances within the road load deter ­
mination, simulation and calculation methods shall not be used to

4. Road load measurement on road  
4.1. Requirements for road test  
4.1.1. Atmospheric conditions for road test  
4.1.1.1. Permissible wind conditions  
The maximum permissible wind conditions for road load deter ­
mination are described in paragraphs 4.1.1.1.1. and 4.1.1.1.2.  
In order to determine the applicability of the type of anemometry to 
be used, the arithmetic average of the wind speed shall be 
determined by continuous wind speed measurement, using a 
recognized meteorological instrument, at a location and height 
above the road level alongside the test road where the most rep ­
resentative wind conditions will be experienced.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 483  
If tests in opposite directions cannot be performed at the same part 
of the test track (e.g. on an oval test track with an obligatory driving 
direction), wind speed and direction at each part of the test track 
shall be measured. In this case the higher measured value 
determines the type of anemometry to be used and the lower 
value the criterion for the allowance of waiving of a wind 
correction.  
4.1.1.1.1. Permissible wind conditions when using stationary anemometry  
Stationary anemometry shall be used only when wind speeds over a 
period of 5 seconds averages less than 5 m/s and peak wind speeds 
are less than 8 m/s for less than 2 seconds. In addition, the vector 
component of the wind speed across the test road shall be less than 
2 m/s. Any wind correction shall be calculated as given in paragraph 
4.5.3. of this Sub-Annex. Wind correction may be waived when the 
lowest arithmetic average wind speed is 2 m/s or less.  
4.1.1.1.2. Wind conditions using on-board anemometry  
For testing with an on-board anemometer, a device shall be used as 
described in paragraph 4.3.2. of this Sub-Annex. The overall 
arithmetic average of the wind speed during the test activity over 
the test road shall be less than 7 m/s with peak wind speeds of less 
than 10 m/s. In addition, the vector component of the wind speed 
across the road shall be less than 4 m/s.  
4.1.1.2. Atmospheric temperature  
The atmospheric temperature should be within the range of 5 °C up 
to and including 35 °C.  
If the difference between the highest and the lowest measured 
temperature during the coastdown test is more than 5 °C, the 
temperature correction shall be applied separately for each run 
with the arithmetic average of the ambient temperature of that run.  
In that case the values of the road load coefficients f  0 , f 1 and f  2 shall 
be determined and corrected for each individual run. The final set of 
f 0 , f 1 and f  2 values shall be the arithmetic average of the indi ­
vidually corrected coefficients f  0 , f 1 and f  2 respectively.  
At its option, a manufacturer may choose to perform coastdowns 
between 1 °C and 5 °C.  
4.1.2. Test road  
The road surface shall be flat, even, clean, dry and free of obstacles 
or wind barriers that might impede the measurement of the road 
load, and its texture and composition shall be representative of 
current urban and highway road surfaces. The longitudinal slope 
of the test road shall not exceed ± 1 per cent. The local slope 
between any points 3 metres apart shall not deviate more than 
± 0,5 per cent from this longitudinal slope. If tests in opposite 
directions cannot be performed at the same part of the test track 
(e.g. on an oval test track with an obligatory driving direction), the 
sum of the longitudinal slopes of the parallel test track segments 
shall be between 0 and an upward slope of 0,1 per cent. The 
maximum camber of the test road shall be 1,5 per cent.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 484  
4.2. Preparation  
4.2.1. Test vehicle  
Each test vehicle shall conform in all its components with the 
production series, or, if the vehicle is different from the production 
vehicle, a full description shall be included in all relevant test 
reports.  
4.2.1.1. Without using the interpolation method  
A test vehicle (vehicle H) with the combination of road load 
relevant characteristics (i.e. mass, aerodynamic drag and tyre 
rolling resistance) producing the highest cycle energy demand 
shall be selected from the interpolation family (see paragraph 5.6. 
of this Annex).  
If the aerodynamic influence of the different wheel rims within one 
interpolation family is not known, the selection shall be based on 
the highest expected aerodynamic drag. As a guideline, the highest 
aerodynamic drag may be expected for a wheel with a) the largest 
width, b) the largest diameter, and c) the most open structure design 
(in that order of importance).  
The wheel selection shall be executed without prejudice to the 
requirement of the highest cycle energy demand.  
4.2.1.2. Using the interpolation method  
At the request of the manufacturer, the interpolation method may be 
applied for individual vehicles in the interpolation family (see 
paragraph 1.2.3.1. of Sub-Annex 6 and paragraph 3.2.3.2. of Sub- 
Annex 7).  
In this case, two test vehicles shall be selected from the interpolation 
family complying with the requirements of the interpolation method 
(paragraphs 1.2.3.1. and 1.2.3.2. of Sub-Annex 6).  
Test vehicle H shall be the vehicle producing the higher, and 
preferably highest, cycle energy demand of that selection, test 
vehicle L the one producing the lower, and preferably lowest, 
cycle energy demand of that selection.  
All items of optional equipment and/or body shapes that are chosen 
not to be considered in the interpolation method shall be fitted to 
both test vehicles H and L such that these items of optional 
equipment produce the highest combination of the cycle energy 
demand due to their road load relevant characteristics (i.e. mass, 
aerodynamic drag and tyre rolling resistance).  
4.2.1.3. Application of the road load family  
4.2.1.3.1. At the request of the manufacturer and upon fulfilling the criteria of 
paragraph 5.7. of this Annex, the road load values for vehicles H 
and L of an interpolation family shall be calculated.  
4.2.1.3.2. For the purposes of paragraph 4.2.1.3. of this Sub-Annex, vehicle H 
of a road load family shall be designated vehicle H  R . All references 
to vehicle H in paragraph 4.2.1. of this Sub-Annex shall be replaced 
by vehicle H  R and all references to an interpolation family in 
paragraph 4.2.1. of this Sub-Annex shall be replaced by road load 
family.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 485  
4.2.1.3.3. For the purposes of paragraph 4.2.1.3. of this Sub-Annex, vehicle L 
of a road load family shall be designated vehicle L  R . All references 
to vehicle L in paragraph 4.2.1. of this Sub-Annex shall be replaced 
by vehicle L  R and all references to an interpolation family in 
paragraph 4.2.1. of this Sub-Annex shall be replaced by road load 
family.  
4.2.1.3.4. Notwithstanding the requirements referring to the range of an inter ­
polation family in paragraphs 1.2.3.1. and 1.2.3.2. of Sub-Annex 6, 
the difference in cycle energy demand between H  R and L  R of the 
road load family shall be at least 4 per cent and shall not exceed 35 
per cent based on H  R over a complete WLTC Class 3 cycle.  
If more than one transmission is included in the road load family, a 
transmission with the highest power losses shall be used for road 
load determination.  
4.2.1.3.5. Road loads H  R and/or L  R shall be determined according to this Sub- 
Annex.  
The road load of vehicles H (and L) of an interpolation family 
within the road load family shall be calculated according to para ­
graphs 3.2.3.2.2. to 3.2.3.2.2.4. inclusive of Sub-Annex 7, by:  
(a) using H  R and L  R of the road load family instead of H and L as 
inputs for the equations;  
(b) using the road load parameters (i.e. test mass, Δ(C D × A  f ) 
compared to vehicle L  R , and tyre rolling resistance) of vehicle 
H (or L) of the interpolation family as inputs for the "individual 
vehicle";  
(c) repeating this calculation for each H and L vehicle of every 
interpolation family within the road load family.  
The road load interpolation shall only be applied on those road load 
relevant characteristics that were identified to be different between 
test vehicle L  R and H  R . For other road load relevant character ­
istic(s), the value of vehicle H  R shall apply.  
4.2.1.4. Application of the road load matrix family  
A vehicle that fulfils the criteria of paragraph 5.8. of this Annex that 
is: 
(a) representative of the intended series of complete vehicles to be 
covered by the road load matrix family in terms of estimated 
worst C  D value and body shape, and  
(b) representative of the intended series of vehicles to be covered 
by the road load matrix family in terms of estimated average of 
the mass of optional equipment, shall be used to determine the 
road load.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 486  
In the case that no representative body shape for a complete vehicle 
can be determined, the test vehicle shall be equipped with a square 
box with rounded corners with radii of maximum of 25 mm and a 
width equal to the maximum width of the vehicles covered by the 
road load matrix family, and a total height of the test vehicle of 3,0 
m ± 0,1 m, including the box.  
The manufacturer and the approval authority shall agree which 
vehicle test model is representative.  
The vehicle parameters test mass, tyre rolling resistance and frontal 
area of both a vehicle H  M and L  M shall be determined in such a way 
that vehicle H  M produces the highest cycle energy demand and 
vehicle L  M the lowest cycle energy from the road load matrix 
family. The manufacturer and the approval authority shall agree 
on the vehicle parameters for vehicle H  M and L  M . 
The road load of all individual vehicles of the road load matrix 
family, including H  M and L  M , shall be calculated according to 
paragraph 5.1. of this Sub-Annex.  
4.2.1.5. Movable aerodynamic body parts  
Movable aerodynamic body parts on the test vehicles shall operate 
during road load determination as intended under WLTP Type 1 test 
conditions (test temperature, vehicle speed and acceleration range, 
engine load, etc.).  
Every vehicle system that dynamically modifies the vehicle’s 
aerodynamic drag (e.g. vehicle height control) shall be considered 
to be a movable aerodynamic body part. Appropriate requirements 
shall be added if future vehicles are equipped with movable 
aerodynamic items of optional equipment whose influence on 
aerodynamic drag justifies the need for further requirements.  
4.2.1.6. Weighing  
Before and after the road load determination procedure, the selected 
vehicle shall be weighed, including the test driver and equipment, to 
determine the arithmetic average mass, m  av . The mass of the vehicle 
shall be greater than or equal to the test mass of vehicle H or of 
vehicle L at the start of the road load determination procedure.  
4.2.1.7. Test vehicle configuration  
The test vehicle configuration shall be included in all relevant test 
reports and shall be used for any subsequent coastdown testing.  
4.2.1.8. Test vehicle condition  
4.2.1.8.1. Run-in  
The test vehicle shall be suitably run-in for the purpose of the 
subsequent test for at least 10 000 but no more than 80 000 km.  
4.2.1.8.1.1. At the request of the manufacturer, a vehicle with a minimum of 
3 000 km may be used.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 487  
4.2.1.8.2. Manufacturer's specifications  
The vehicle shall conform to the manufacturer’s intended production 
vehicle specifications regarding tyre pressures described in 
paragraph 4.2.2.3. of this Sub-Annex, wheel alignment described 
in paragraph 4.2.1.8.3. of this Sub-Annex, ground clearance, 
vehicle height, drivetrain and wheel bearing lubricants, and brake 
adjustment to avoid unrepresentative parasitic drag.  
4.2.1.8.3. Wheel alignment  
Toe and camber shall be set to the maximum deviation from the 
longitudinal axis of the vehicle in the range defined by the manu ­
facturer. If a manufacturer prescribes values for toe and camber for 
the vehicle, these values shall be used. At the request of the manu ­
facturer, values with higher deviations from the longitudinal axis of 
the vehicle than the prescribed values may be used. The prescribed 
values shall be the reference for all maintenance during the lifetime 
of the vehicle.  
Other adjustable wheel alignment parameters (such as caster) shall 
be set to the values recommended by the manufacturer. In the 
absence of recommended values, they shall be set to the arithmetic 
average of the range defined by the manufacturer.  
Such adjustable parameters and set values shall be included in all 
relevant test sheets.  
4.2.1.8.4. Closed panels  
During the road load determination, the engine compartment cover, 
luggage compartment cover, manually-operated movable panels and 
all windows shall be closed.  
4.2.1.8.5. Coastdown mode  
If the determination of dynamometer settings cannot meet the 
criteria described in paragraphs 8.1.3. or 8.2.3. of this Sub-Annex 
due to non-reproducible forces, the vehicle shall be equipped with a 
vehicle coastdown mode. The coastdown mode shall be approved by 
the approval authority and the use of a coastdown mode shall be 
included in all relevant test reports.  
4.2.1.8.5.1. If a vehicle is equipped with a vehicle coastdown mode, it shall be 
engaged both during road load determination and on the chassis 
dynamometer.  
4.2.2. Tyres

Sub-Annex with their rolling resistances measured according to 
Annex 6 of UN/ECE Regulation No. 11702 series of amendments.  
The rolling resistance coefficients shall be aligned and categorised 
according to the rolling resistance classes in Regulation (EC) 
No 1222/2009.  ▼B

The actual rolling resistance values for the tyres fitted to the test 
vehicles shall be used to determine the gradient of the interpolation 
line of the interpolation method in paragraph 3.2.3.2 of Sub-Annex 
7. For individual vehicles in the interpolation family, the inter ­

mination;  
(d) Have a constant tread depth before the test between 100 and 80

All vehicles shall be driven at 90 per cent of the maximum speed of 
the applicable WLTC. The vehicle may be driven at 90 per cent of 
the maximum speed of the next higher phase (see Table A4/2) if 
this phase is added to the applicable WLTC warm-up procedure as 
defined in paragraph 7.3.4. of this Sub-Annex. The vehicle shall be

means of operation on the test vehicle where such calibration occurs 
during the warm-up for the test.  
4.3.2.1.1. Relative wind speed shall be measured at a minimum frequency of

frequency of 5 Hz. Ambient temperature shall be synchronised and 
sampled at a minimum frequency of 1 Hz.  
4.3.2.4. Vehicle coastdown procedure  
The measurements shall be carried out in opposite directions until a

run in the opposite direction shall be rejected. All valid pairs shall 
be included in the final analysis with a minimum of 5 pairs of 
coastdown runs. See paragraph 4.3.2.6.10. of this Sub-Annex for

anemometer shall be mounted within 30 cm from the top of 
the windshield.  
(c) On the engine compartment cover of the vehicle at its 
centreline, mounted at the midpoint position between the 
vehicle front and the base of the windshield.  
In all cases, the anemometer shall be mounted parallel to the road 
surface. In the event that positions (b) or (c) are used, the coastdown 
results shall be analytically adjusted for the additional aerodynamic 
drag induced by the anemometer. The adjustment shall be made by 
testing the coastdown vehicle in a wind tunnel both with and 
without the anemometer installed in the same position as used on 
the track., The calculated difference shall be the incremental 
aerodynamic drag coefficient C  D combined with the frontal area, 
which shall be used to correct the coastdown results.  
4.3.2.4.1. Following the vehicle warm-up procedure described in paragraph 
4.2.4. of this Sub-Annex and immediately prior to each test 
measurement, the vehicle shall be accelerated to 10 to 15 km/h 
above the highest reference speed and shall be driven at that

collected in a single run for all the reference speed points. For split 
runs, care shall be taken so that vehicle conditions remain as stable 
as possible at each split point.

road load matrix family, the coefficient B  m shall be set to zero and 
the coefficients A  m and C  m shall be recalculated with a least squares 
regression analysis.

A three-term equation shall be generated to describe the road load 
force as a function of velocity, F = A + Bv + Cv  2 , corrected to 
standard ambient temperature and pressure conditions, and in still 
air. The method for this analysis process is described in paragraphs 
4.3.2.6.1. to 4.3.2.6.10. inclusive in this Sub-Annex.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 497  
4.3.2.6.1. Determining calibration coefficients  
If not previously determined, calibration factors to correct for 
vehicle blockage shall be determined for relative wind speed and 
yaw angle. Vehicle speed v, relative wind velocity v  r and yaw Y 
measurements during the warm-up phase of the test procedure shall 
be recorded. Paired runs in alternate directions on the test track at a 
constant velocity of 80 km/h shall be performed, and the arithmetic 
average values of v, v  r and Y for each run shall be determined. 
Calibration factors that minimise the total errors in head and cross 
winds over all the run pairs, i.e. the sum of (head  i – head  i+1 ) 2 , etc., 
shall be selected where head  i and head  i+1 refer to wind speed and 
wind direction from the paired test runs in opposing directions 
during the vehicle warm-up/stabilization prior to testing.

Data points gathered where yaw angles are greater than ± 20 
degrees from the direction of vehicle travel shall be flagged. Data 
points gathered where relative wind is less than + 5 km/h (to avoid 
conditions where tailwind speed is higher than vehicle speed) shall 
also be flagged. Data analysis shall be restricted to vehicle speeds 
within the speed range selected according to paragraph 4.3.2.2. of 
this Sub-Annex.  
4.3.2.6.7. Final data analysis

constrained analysis may be applied such that the vehicle’s frontal 
area, A  f , and the drag coefficient, C  D , may be fixed if they have 
been previously determined.  
4.3.2.6.9. Correction to reference conditions  
Equations of motion shall be corrected to reference conditions as 
specified in paragraph 4.5. of this Sub-Annex.  
4.3.2.6.10. Statistical criteria for on-board anemometry  
The exclusion of each single pair of coastdown runs shall change 
the calculated road load for each coastdown reference speed v  j less 
than the convergence requirement, for all i and j:

In the case that the convergence requirement is not met, pairs shall 
be removed from the analysis, starting with the pair giving the 
highest change in calculated road load, until the convergence 
requirement is met, as long as a minimum of 5 valid pairs are 
used for the final road load determination.  
4.4. Measurement and calculation of running resistance using the torque 
meter method  
As an alternative to the coastdown methods, the torque meter 
method may also be used in which the running resistance is 
determined by measuring wheel torque on the driven wheels at 
the reference speed points for time periods of at least 5 seconds.  
4.4.1. Installation of torque meter

4.4.2.2. Data collection  
Data sets consisting of actual speed v  ji actual torque C  ji and time 
over a period of at least 5 seconds shall be measured for every v  j at 
a sampling frequency of at least 10 Hz. The data sets collected over 
one time period for a reference speed v  j shall be referred to as one 
measurement.  
4.4.2.3. Vehicle torque meter measurement procedure  
Prior to the torque meter method test measurement, a vehicle warm- 
up shall be performed according to paragraph 4.2.4. of this Sub- 
Annex.  
During test measurement, steering wheel movement shall be avoided 
as much as possible, and the vehicle brakes shall not be operated.  
The test shall be repeated until the running resistance data satisfy 
the measurement precision requirements as specified in paragraph 
4.4.3.2. of this Sub-Annex.  
Although it is recommended that each test run be performed without 
interruption, split runs may be performed if data cannot be collected 
in a single run for all the reference speed points. For split runs, care 
shall be taken so that vehicle conditions remain as stable as possible 
at each split point  
4.4.2.4. Velocity deviation  
During a measurement at a single reference speed point, the velocity 
deviation from the arithmetic average velocity, v  ji –v jm , calculated 
according to paragraph 4.4.3. of this Sub-Annex, shall be within 
the values in Table A4/5.  
Additionally, the arithmetic average velocity v  jm at every reference 
speed point shall not deviate from the reference speed v  j by more 
than ± 1 km/h or 2 per cent of the reference speed v  j , whichever is 
greater.

vehicle exhaust shall be continuously diluted with ambient air 
under controlled conditions using a constant volume sampler. A 
critical flow venturi (CFV) or multiple critical flow venturis 
arranged in parallel, a positive displacement pump (PDP), a 
subsonic venturi (SSV), or an ultrasonic flow meter (UFM) may 
be used. The total volume of the mixture of exhaust and dilution 
air shall be measured and a continuously proportional sample of 
the volume shall be collected for analysis. The quantities of 
exhaust gas compounds shall be determined from the sample 
concentrations, corrected for their respective content of the 
dilution air and the totalised flow over the test period.  
3.1.1.2. The exhaust dilution system shall consist of a connecting tube, a 
mixing device and dilution tunnel, dilution air conditioning, a 
suction device and a flow measurement device. Sampling probes 
shall be fitted in the dilution tunnel as specified in paragraphs 4.1., 
4.2. and 4.3. of this Sub-Annex.  
3.1.1.3. The mixing device referred to in paragraph 3.1.1.2. of this Sub- 
Annex shall be a vessel such as that illustrated in Figure A5/3 in 
which vehicle exhaust gases and the dilution air are combined so 
as to produce a homogeneous mixture at the sampling position.  
3.2. General requirements  
3.2.1. The vehicle exhaust gases shall be diluted with a sufficient 
amount of ambient air to prevent any water condensation in the 
sampling and measuring system at all conditions that may occur 
during a test.  
3.2.2. The mixture of air and exhaust gases shall be homogeneous at the 
point where the sampling probes are located (paragraph 3.3.3. of 
this Sub-Annex). The sampling probes shall extract representative 
samples of the diluted exhaust gas.  
3.2.3. The system shall enable the total volume of the diluted exhaust 
gases to be measured.  
3.2.4. The sampling system shall be gas-tight. The design of the variable 
dilution sampling system and the materials used in its construction 
shall be such that the concentration of any compound in the 
diluted exhaust gases is not affected. If any component in the 
system (heat exchanger, cyclone separator, suction device, etc.) 
changes the concentration of any of the exhaust gas compounds 
and the systematic error cannot be corrected, sampling for that 
compound shall be carried out upstream from that component.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 532  
3.2.5. All parts of the dilution system in contact with raw or diluted 
exhaust gas shall be designed to minimise deposition or alteration 
of the particulate or particles. All parts shall be made of elec ­
trically conductive materials that do not react with exhaust gas 
components, and shall be electrically grounded to prevent elec ­
trostatic effects.  
3.2.6. If the vehicle being tested is equipped with an exhaust pipe 
comprising several branches, the connecting tubes shall be 
connected as near as possible to the vehicle without adversely 
affecting their operation.  
3.3. Specific requirements  
3.3.1. Connection to vehicle exhaust  
3.3.1.1. The start of the connecting tube is the exit of the tailpipe. The end 
of the connecting tube is the sample point, or first point of 
dilution.  
For multiple tailpipe configurations where all the tailpipes are 
combined, the start of the connecting tube shall be taken at the 
last joint of where all the tailpipes are combined. In this case, the 
tube between the exit of the tailpipe and the start of the connecting 
tube may or may not be insulated or heated.  
3.3.1.2. The connecting tube between the vehicle and dilution system shall 
be designed so as to minimize heat loss.  
3.3.1.3. The connecting tube shall satisfy the following requirements:  
(a) Be less than 3.6 metres long, or less than 6.1 metres long if 
heat-insulated. Its internal diameter shall not exceed 105 mm; 
the insulating materials shall have a thickness of at least 25 
mm and thermal conductivity shall not exceed 0,1 W/m  –1 K –1 
at 400 °C. Optionally, the tube may be heated to a 
temperature above the dew point. This may be assumed to 
be achieved if the tube is heated to 70 °C;  
(b) Not cause the static pressure at the exhaust outlets on the 
vehicle being tested to differ by more than ± 0,75 kPa at 50 
km/h, or more than ± 1,25 kPa for the duration of the test 
from the static pressures recorded when nothing is connected 
to the vehicle exhaust pipes. The pressure shall be measured 
in the exhaust outlet or in an extension having the same 
diameter and as near as possible to the end of the tailpipe. 
Sampling systems capable of maintaining the static pressure to 
within ± 0,25 kPa may be used if a written request from a 
manufacturer to the approval authority substantiates the need 
for the closer tolerance;  
(c) No component of the connecting tube shall be of a material 
that might affect the gaseous or solid composition of the 
exhaust gas. To avoid generation of any particles from 
elastomer connectors, elastomers employed shall be as 
thermally stable as possible and have minimum exposure to 
the exhaust gas. It is recommended not to use elastomer 
connectors to bridge the connection between the vehicle 
exhaust and the connecting tube.  
3.3.2. Dilution air conditioning  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 533  
3.3.2.1. The dilution air used for the primary dilution of the exhaust in the 
CVS tunnel shall pass through a medium capable of reducing 
particles of the most penetrating particle size in the filter 
material by ≤ 99,95 per cent, or through a filter of at least class 
H13 of EN 1822:2009. This represents the specification of High 
Efficiency Particulate Air (HEPA) filters. The dilution air may 
optionally be charcoal-scrubbed before being passed to the 
HEPA filter. It is recommended that an additional coarse 
particle filter be situated before the HEPA filter and after the 
charcoal scrubber, if used.  
3.3.2.2. At the vehicle manufacturer's request, the dilution air may be 
sampled according to good engineering practice to determine the 
tunnel contribution to background particulate and particle levels, 
which can be subsequently subtracted from the values measured in 
the diluted exhaust. See paragraph 1.2.1.3. of Sub-Annex 6.  
3.3.3. Dilution tunnel  
3.3.3.1. Provision shall be made for the vehicle exhaust gases and the 
dilution air to be mixed. A mixing device may be used.  
3.3.3.2. The homogeneity of the mixture in any cross-section at the 
location of the sampling probe shall not vary by more than ± 2 
per cent from the arithmetic average of the values obtained for at 
least five points located at equal intervals on the diameter of the 
gas stream.  
3.3.3.3. For PM and PN emissions sampling, a dilution tunnel shall be 
used that:  
(a) Consists of a straight tube of electrically-conductive material 
that is grounded;  
(b) Causes turbulent flow (Reynolds number ≥ 4 000) and be of 
sufficient length to cause complete mixing of the exhaust and 
dilution air;  
(c) Is at least 200 mm in diameter;  
(d) May be insulated and/or heated.  
3.3.4. Suction device  
3.3.4.1. This device may have a range of fixed speeds to ensure sufficient 
flow to prevent any water condensation. This result is obtained if 
the flow is either:  
(a) Twice as high as the maximum flow of exhaust gas produced 
by accelerations of the driving cycle; or  
(b) Sufficient to ensure that the CO  2 concentration in the dilute 
exhaust sample bag is less than 3 per cent by volume for 
petrol and diesel, less than 2.2 per cent by volume for LPG 
and less than 1.5 per cent by volume for NG/biomethane.  
3.3.4.2. Compliance with the requirements in paragraph 3.3.4.1. of this 
Sub-Annex may not be necessary if the CVS system is designed 
to inhibit condensation by such techniques, or combination of 
techniques, as:  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 534  
(a) Reducing water content in the dilution air (dilution air dehu ­
midification);  
(b) Heating of the CVS dilution air and of all components up to 
the diluted exhaust flow measurement device and, optionally, 
the bag sampling system including the sample bags and also 
the system for the measurement of the bag concentrations.  
In such cases, the selection of the CVS flow rate for the test shall 
be justified by showing that condensation of water cannot occur at 
any point within the CVS, bag sampling or analytical system.  
3.3.5. Volume measurement in the primary dilution system  
3.3.5.1. The method of measuring total dilute exhaust volume incorporated 
in the constant volume sampler shall be such that measurement is 
accurate to ± 2 per cent under all operating conditions. If the 
device cannot compensate for variations in the temperature of 
the mixture of exhaust gases and dilution air at the measuring 
point, a heat exchanger shall be used to maintain the temperature 
to within ± 6 °C of the specified operating temperature for a PDP 
CVS, ± 11 °C for a CFV CVS, ± 6 °C for a UFM CVS, and 
± 11 °C for an SSV CVS.  
3.3.5.2. If necessary, some form of protection for the volume measuring 
device may be used e.g. a cyclone separator, bulk stream filter, 
etc. 
3.3.5.3. A temperature sensor shall be installed immediately before the 
volume measuring device. This temperature sensor shall have an 
accuracy and a precision of ± 1 °C and a response time of 0,1 
seconds at 62 per cent of a given temperature variation (value 
measured in silicone oil).  
3.3.5.4. Measurement of the pressure difference from atmospheric pressure 
shall be taken upstream from and, if necessary, downstream from 
the volume measuring device.  
3.3.5.5. The pressure measurements shall have a precision and an accuracy 
of ± 0,4 kPa during the test. See Table A5/5.  
3.3.6. Recommended system description  
Figure A5/3 is a schematic drawing of exhaust dilution systems 
that meet the requirements of this Sub-Annex.  
The following components are recommended:  
(a) A dilution air filter, which may be pre-heated if necessary. 
This filter shall consist of the following filters in sequence: an 
optional activated charcoal filter (inlet side), and a HEPA filter 
(outlet side). It is recommended that an additional coarse 
particle filter be situated before the HEPA filter and after 
the charcoal filter, if used. The purpose of the charcoal filter 
is to reduce and stabilize the hydrocarbon concentrations of 
ambient emissions in the dilution air;  ▼B

(b) A connecting tube by which vehicle exhaust is admitted into a 
dilution tunnel;  
(c) An optional heat exchanger as described in paragraph 3.3.5.1. 
of this Sub-Annex;  
(d) A mixing device in which exhaust gas and dilution air are 
mixed homogeneously, and which may be located close to the 
vehicle so that the length of the connecting tube is minimized;  
(e) A dilution tunnel from which particulate and particles are 
sampled;  
(f) Some form of protection for the measurement system may be 
used e.g. a cyclone separator, bulk stream filter, etc.;  
(g) A suction device of sufficient capacity to handle the total 
volume of diluted exhaust gas.  
Exact conformity with these figures is not essential. Additional 
components such as instruments, valves, solenoids and switches 
may be used to provide additional information and co-ordinate the 
functions of the component system.

3.3.6.1. Positive displacement pump (PDP)  
3.3.6.1.1. A positive displacement pump (PDP) full flow exhaust dilution 
system satisfies the requirements of this Sub-Annex by metering 
the flow of gas through the pump at constant temperature and 
pressure. The total volume is measured by counting the revol ­
utions made by the calibrated positive displacement pump. The 
proportional sample is achieved by sampling with pump, flow 
meter and flow control valve at a constant flow rate.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 536  
3.3.6.2. Critical flow venturi (CFV)  
3.3.6.2.1. The use of a CFV for the full flow exhaust dilution system is 
based on the principles of flow mechanics for critical flow. The 
variable mixture flow rate of dilution and exhaust gas is main ­
tained at sonic velocity that is directly proportional to the square 
root of the gas temperature. Flow is continually monitored, 
computed and integrated throughout the test.  
3.3.6.2.2. The use of an additional critical flow sampling venturi ensures the 
proportionality of the gas samples taken from the dilution tunnel. 
As both pressure and temperature are equal at the two venturi 
inlets, the volume of the gas flow diverted for sampling is propor ­
tional to the total volume of diluted exhaust gas mixture produced, 
and thus the requirements of this Sub-Annex are fulfilled.  
3.3.6.2.3. A measuring CFV tube shall measure the flow volume of the 
diluted exhaust gas.  
3.3.6.3. Subsonic flow venturi (SSV)  
3.3.6.3.1. The use of an SSV (Figure A5/4) for a full flow exhaust dilution 
system is based on the principles of flow mechanics. The variable 
mixture flow rate of dilution and exhaust gas is maintained at a 
subsonic velocity that is calculated from the physical dimensions 
of the subsonic venturi and measurement of the absolute 
temperature (T) and pressure (P) at the venturi inlet and the 
pressure in the throat of the venturi. Flow is continually moni ­
tored, computed and integrated throughout the test.  
3.3.6.3.2. An SSV shall measure the flow volume of the diluted exhaust gas.  
Figure A5/4  
Schematic of a subsonic venturi tube (SSV)
  
3.3.6.4. Ultrasonic flow meter (UFM)  
3.3.6.4.1. A UFM measures the velocity of the diluted exhaust gas in the 
CVS piping using the principle of ultrasonic flow detection by 
means of a pair, or multiple pairs, of ultrasonic transmitters/re ­
ceivers mounted within the pipe as in Figure A5/5. The velocity of 
the flowing gas is determined by the difference in the time 
required for the ultrasonic signal to travel from transmitter to 
receiver in the upstream direction and the downstream direction. 
The gas velocity is converted to standard volumetric flow using a 
calibration factor for the tube diameter with real time corrections 
for the diluted exhaust temperature and absolute pressure.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 537  
3.3.6.4.2. Components of the system include:  
(a) A suction device fitted with speed control, flow valve or other 
method for setting the CVS flow rate and also for maintaining 
constant volumetric flow at standard conditions;  
(b) A UFM;  
(c) Temperature and pressure measurement devices, T and P, 
required for flow correction;  
(d) An optional heat exchanger for controlling the temperature of 
the diluted exhaust to the UFM. If installed, the heat 
exchanger shall be capable of controlling the temperature of 
the diluted exhaust to that specified in paragraph 3.3.5.1. of 
this Sub-Annex. Throughout the test, the temperature of the 
air/exhaust gas mixture measured at a point immediately 
upstream of the suction device shall be within ± 6 °C of 
the arithmetic average operating temperature during the test.  
Figure A5/5  
Schematic of an ultrasonic flow meter (UFM)
  
3.3.6.4.3. The following conditions shall apply to the design and use of the 
UFM type CVS:  
(a) The velocity of the diluted exhaust gas shall provide a 
Reynolds number higher than 4 000 in order to maintain a 
consistent turbulent flow before the ultrasonic flow meter;  
(b) An ultrasonic flow meter shall be installed in a pipe of 
constant diameter with a length of 10 times the internal 
diameter upstream and 5 times the diameter downstream;  
(c) A temperature sensor (T) for the diluted exhaust shall be 
installed immediately before the ultrasonic flow meter. This 
sensor shall have an accuracy and a precision of ± 1 °C and a 
response time of 0,1 seconds at 62 per cent of a given 
temperature variation (value measured in silicone oil);  
(d) The absolute pressure (P) of the diluted exhaust shall be 
measured immediately before the ultrasonic flow meter to 
within ± 0,3 kPa;  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 538  
(e) If a heat exchanger is not installed upstream of the ultrasonic 
flow meter, the flow rate of the diluted exhaust, corrected to 
standard conditions, shall be maintained at a constant level 
during the test. This may be achieved by control of the 
suction device, flow valve or other method.  
3.4. CVS calibration procedure  
3.4.1. General requirements  
3.4.1.1. The CVS system shall be calibrated by using an accurate flow 
meter and a restricting device and at the intervals listed in Table 
A5/4. The flow through the system shall be measured at various 
pressure readings and the control parameters of the system 
measured and related to the flows. The flow metering device 
(e.g. calibrated venturi, laminar flow element (LFE), calibrated 
turbine meter) shall be dynamic and suitable for the high flow 
rate encountered in constant volume sampler testing. The device 
shall be of certified accuracy traceable to an approved national or 
international standard.  
3.4.1.2. The following paragraphs describe methods for calibrating PDP, 
CFV, SSV and UFM units using a laminar flow meter, which 
gives the required accuracy, along with a statistical check on the 
calibration validity.  
3.4.2. Calibration of a positive displacement pump (PDP)  
3.4.2.1. The following calibration procedure outlines the equipment, the 
test configuration and the various parameters that are measured to 
establish the flow rate of the CVS pump. All the parameters 
related to the pump are simultaneously measured with the 
parameters related to the flow meter that is connected in series 
with the pump. The calculated flow rate (given in m  3 /min at pump 
inlet for the measured absolute pressure and temperature) shall be 
subsequently plotted versus a correlation function that includes the 
relevant pump parameters. The linear equation that relates the 
pump flow and the correlation function shall be subsequently 
determined. In the case that a CVS has a multiple speed drive, 
a calibration for each range used shall be performed.  
3.4.2.2. This calibration procedure is based on the measurement of the 
absolute values of the pump and flow meter parameters relating 
the flow rate at each point. The following conditions shall be 
maintained to ensure the accuracy and integrity of the calibration 
curve:  
3.4.2.2.1. The pump pressures shall be measured at tappings on the pump 
rather than at the external piping on the pump inlet and outlet. 
Pressure taps that are mounted at the top centre and bottom centre 
of the pump drive head plate are exposed to the actual pump 
cavity pressures, and therefore reflect the absolute pressure differ ­
entials.  
3.4.2.2.2. Temperature stability shall be maintained during the calibration. 
The laminar flow meter is sensitive to inlet temperature oscil ­
lations that cause data points to be scattered. Gradual changes 
of ± 1 °C in temperature are acceptable as long as they occur 
over a period of several minutes.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 539  
3.4.2.2.3. All connections between the flow meter and the CVS pump shall 
be free of leakage.  
3.4.2.3. During an exhaust emissions test, the measured pump parameters 
shall be used to calculate the flow rate from the calibration 
equation.  
3.4.2.4. Figure A5/6 of this Sub-Annex shows an example of a calibration 
set-up. Variations are permissible, provided that the approval 
authority approves them as being of comparable accuracy. If the 
set-up shown in Figure A5/6 is used, the following data shall be 
found within the limits of accuracy given:  
Barometric pressure (corrected), P  b ± 0,03 kPa  
Ambient temperature, T ± 0,2 K  
Air temperature at LFE, ETI ± 0,15 K  
Pressure depression upstream of LFE, EPI ± 0,01 kPa  
Pressure drop across the LFE matrix, EDP ± 0,0015 kPa  
Air temperature at CVS pump inlet, PTI ± 0,2 K  
Air temperature at CVS pump outlet, PTO ± 0,2 K  
Pressure depression at CVS pump inlet, PPI ± 0,22 kPa  
Pressure head at CVS pump outlet, PPO ± 0,22 kPa

3.4.2.5. After the system has been connected as shown in Figure A5/6., 
the variable restrictor shall be set in the wide-open position and 
the CVS pump shall run for 20 minutes before starting the cali ­
bration.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 540  
3.4.2.5.1. The restrictor valve shall be reset to a more restricted condition in 
increments of pump inlet depression (about 1 kPa) that will yield a 
minimum of six data points for the total calibration. The system 
shall be allowed to stabilize for 3 minutes before the data 
acquisition is repeated.  
3.4.2.5.2. The air flow rate Q  s at each test point shall be calculated in 
standard m  3 /min from the flow meter data using the manufac ­
turer's prescribed method.  
3.4.2.5.3. The air flow rate shall be subsequently converted to pump flow V  0 
in m  3 /rev at absolute pump inlet temperature and pressure.  
V 0 ¼ Q s 
n Ü T p 
273,15 K Ü 101,325 kPa 
P p 
where:  
V 0 is the pump flow rate at T  p and P  p , m  3 /rev; 
Q s is the air flow at 101,325 kPa and 273,15 K (0 °C), m  3 /min;  
T p is the pump inlet temperature, Kelvin (K);  
P p is the absolute pump inlet pressure, kPa;  
n is the pump speed, min  –1 . 
3.4.2.5.4. To compensate for the interaction of pump speed pressure vari ­
ations at the pump and the pump slip rate, the correlation function 
x 0 between the pump speed n, the pressure differential from pump 
inlet to pump outlet and the absolute pump outlet pressure shall be 
calculated using the following equation:  
x 0 ¼ 1 
n ﬃﬃﬃﬃﬃﬃﬃﬃ 
ΔP p 
P e s 
where:  
x 0 is the correlation function;  
ΔP p is the pressure differential from pump inlet to pump outlet, 
kPa; 
P e absolute outlet pressure (PPO + P  b ), kPa.  
A linear least squares fit shall be performed to generate the cali ­
bration equations having the following form:  
V 0 ¼ D 0 Ä M Ü x 0 
n ¼ A Ä B Ü ΔP p 
where B and M are the slopes, and A and D  0 are the intercepts of 
the lines.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 541  
3.4.2.6. A CVS system having multiple speeds shall be calibrated at each 
speed used. The calibration curves generated for the ranges shall 
be approximately parallel and the intercept values, D  0 shall 
increase as the pump flow range decreases.  
3.4.2.7. The calculated values from the equation shall be within 0.5 per 
cent of the measured value of V  0 . Values of M will vary from one 
pump to another. A calibration shall be performed at initial instal ­
lation and after major maintenance.  
3.4.3. Calibration of a critical flow venturi (CFV)  
3.4.3.1. Calibration of a CFV is based upon the flow equation for a critical 
venturi:  
Q s ¼ K v P ﬃﬃﬃ 
T p 
where:  
Q s is the flow, m  3 /min;  
K v is the calibration coefficient;  
P is the absolute pressure, kPa;  
T is the absolute temperature, Kelvin (K).  
Gas flow is a function of inlet pressure and temperature.  
The calibration procedure described in paragraph 3.4.3.2. to 
3.4.3.3.3.4. inclusive of this Sub-Annex establishes the value of 
the calibration coefficient at measured values of pressure, 
temperature and air flow.  
3.4.3.2. Measurements for flow calibration of a critical flow venturi are 
required and the following data shall be within the limits of 
precision given:  
Barometric pressure (corrected), P  b ± 0,03 kPa,  
LFE air temperature, flow meter, ETI ± 0,15 K,  
Pressure depression upstream of LFE, EPI ± 0,01 kPa,  
Pressure drop across LFE matrix, EDP ± 0,0015 kPa,  
Air flow, Q  s ± 0,5 per cent,  
CFV inlet depression, PPI ± 0,02 kPa,  
Temperature at venturi inlet, T  v ± 0,2 K.  
3.4.3.3. The equipment shall be set up as shown in Figure A5/7 and 
checked for leaks. Any leaks between the flow-measuring device 
and the critical flow venturi will seriously affect the accuracy of 
the calibration and shall therefore be prevented.  ▼B

CFV calibration configuration
  
3.4.3.3.1. The variable-flow restrictor shall be set to the open position, the 
suction device shall be started and the system stabilized. Data 
from all instruments shall be collected.  
3.4.3.3.2. The flow restrictor shall be varied and at least eight readings 
across the critical flow range of the venturi shall be made.  
3.4.3.3.3. The data recorded during the calibration shall be used in the 
following calculation:  
3.4.3.3.3.1. The air flow rate, Q  s at each test point shall be calculated from the 
flow meter data using the manufacturer's prescribed method.  
Values of the calibration coefficient shall be calculated for each 
test point:  
K v ¼ Q s ﬃﬃﬃﬃﬃ T v p 
P v 
where:  
Q s is the flow rate, m  3 /min at 273,15 K (0 °C) and 101,325, 
kPa; 
T v is the temperature at the venturi inlet, Kelvin (K);  
P v is the absolute pressure at the venturi inlet, kPa.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 543  
3.4.3.3.3.2. K  v shall be plotted as a function of venturi inlet pressure P  v . For 
sonic flow K  v will have a relatively constant value. As pressure 
decreases (vacuum increases), the venturi becomes unchoked and 
K v decreases. These values of K  v shall not be used for further 
calculations.  
3.4.3.3.3.3. For a minimum of eight points in the critical region, an arithmetic 
average K  v and the standard deviation shall be calculated.  
3.4.3.3.3.4. If the standard deviation exceeds 0,3 per cent of the arithmetic 
average K  v , corrective action shall be taken.  
3.4.4. Calibration of a subsonic venturi (SSV)  
3.4.4.1. Calibration of the SSV is based upon the flow equation for a 
subsonic venturi. Gas flow is a function of inlet pressure and 
temperature, and the pressure drop between the SSV inlet and 
throat.  
3.4.4.2. Data analysis  
3.4.4.2.1. The airflow rate, Q  ssv , at each restriction setting (minimum 16 
settings) shall be calculated in standard m  3 /s from the flow 
meter data using the manufacturer's prescribed method. The 
discharge coefficient, C  d , shall be calculated from the calibration 
data for each setting using the following equation:  
C d ¼ Q SSV

To determine the range of subsonic flow, C  d shall be plotted as a 
function of Reynolds number Re at the SSV throat. The Reynolds 
number at the SSV throat shall be calculated using the following 
equation:

S is 110,4 (empirical constant), Kelvin (K).  
3.4.4.2.2. Because Q  SSV is an input to the Re equation, the calculations shall 
be started with an initial guess for Q  SSV or C  d of the calibration 
venturi, and repeated until Q  SSV converges. The convergence 
method shall be accurate to at least 0.1 per cent.  
3.4.4.2.3. For a minimum of sixteen points in the region of subsonic flow, 
the calculated values of C  d from the resulting calibration curve fit 
equation shall be within ± 0,5 per cent of the measured C  d for 
each calibration point.  
3.4.5. Calibration of an ultrasonic flow meter (UFM)  
3.4.5.1. The UFM shall be calibrated against a suitable reference flow 
meter.  
3.4.5.2. The UFM shall be calibrated in the CVS configuration that will be 
used in the test cell (diluted exhaust piping, suction device) and 
checked for leaks. See Figure A5/8.  
3.4.5.3. A heater shall be installed to condition the calibration flow in the 
event that the UFM system does not include a heat exchanger.  
3.4.5.4. For each CVS flow setting that will be used, the calibration shall 
be performed at temperatures from room temperature to the 
maximum that will be experienced during vehicle testing.  
3.4.5.5. The manufacturer's recommended procedure shall be followed for 
calibrating the electronic portions (temperature (T) and pressure 
(P) sensors) of the UFM.

Temperature at UFM inlet, T  act ± 0,2 K.  
3.4.5.7. Procedure  
3.4.5.7.1. The equipment shall be set up as shown in Figure A5/8 and 
checked for leaks. Any leaks between the flow-measuring device 
and the UFM will seriously affect the accuracy of the calibration.  
Figure A5/8  
UFM calibration configuration
  
3.4.5.7.2. The suction device shall be started. Its speed and/or the position of 
the flow valve shall be adjusted to provide the set flow for the 
validation and the system stabilised. Data from all instruments 
shall be collected.  
3.4.5.7.3. For UFM systems without a heat exchanger, the heater shall be 
operated to increase the temperature of the calibration air, allowed 
to stabilise and data from all the instruments recorded. The 
temperature shall be increased in reasonable steps until the 
maximum expected diluted exhaust temperature expected during 
the emissions test is reached.  
3.4.5.7.4. The heater shall be subsequently turned off and the suction device 
speed and/or flow valve shall be adjusted to the next flow setting 
that will be used for vehicle emissions testing after which the 
calibration sequence shall be repeated.  
3.4.5.8. The data recorded during the calibration shall be used in the 
following calculations. The air flow rate Q  s at each test point 
shall be calculated from the flow meter data using the manufac ­
turer's prescribed method. 
K v ¼ Q reference  
Q s 
where:  
Q s is the air flow rate at standard conditions (101,325 kPa, 
273,15 K (0 °C)), m  3 /s; 
Q reference  is the air flow rate of the calibration flow meter at 
standard conditions (101,325 kPa, 273,15 K (0 °C)), 
m 3 /s; ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 546  
K v is the calibration coefficient.  
For UFM systems without a heat exchanger, K  v shall be plotted as 
a function of T  act . 
The maximum variation in K  v shall not exceed 0,3 per cent of the 
arithmetic average K  v value of all the measurements taken at the 
different temperatures.  
3.5. System verification procedure  
3.5.1. General requirements  
3.5.1.1. The total accuracy of the CVS sampling system and analytical 
system shall be determined by introducing a known mass of an 
emissions gas compound into the system whilst it is being 
operated under normal test conditions and subsequently 
analysing and calculating the emission gas compounds according 
to the equations of Sub-Annex 7. The CFO method described in 
paragraph 3.5.1.1.1. of this Sub-Annex and the gravimetric 
method described in paragraph 3.5.1.1.2. of this Sub-Annex are 
both known to give sufficient accuracy.  
The maximum permissible deviation between the quantity of gas 
introduced and the quantity of gas measured is 2 per cent.  
3.5.1.1.1. Critical flow orifice (CFO) method  
The CFO method meters a constant flow of pure gas (CO, CO  2 , or 
C 3 H 8 ) using a critical flow orifice device.  
3.5.1.1.1.1. A known mass of pure carbon monoxide, carbon dioxide or 
propane gas shall be introduced into the CVS system through 
the calibrated critical orifice. If the inlet pressure is high 
enough, the flow rate q which is restricted by means of the 
critical flow orifice, is independent of orifice outlet pressure 
(critical flow). The CVS system shall be operated as in a 
normal exhaust emissions test and enough time shall be allowed 
for subsequent analysis. The gas collected in the sample bag shall 
be analysed by the usual equipment (paragraph 4.1. of this Sub- 
Annex) and the results compared to the concentration of the 
known gas samples If deviations exceed 2 per cent, the cause of 
the malfunction shall be determined and corrected.  
3.5.1.1.2. Gravimetric method  
The gravimetric method weighs a quantity of pure gas (CO, CO  2 , 
or C  3 H 8 ). 
3.5.1.1.2.1. The weight of a small cylinder filled with either pure carbon 
monoxide, carbon dioxide or propane shall be determined with a 
precision of ± 0,01 g. The CVS system shall operate under normal 
exhaust emissions test conditions while the pure gas is injected 
into the system for a time sufficient for subsequent analysis. The 
quantity of pure gas involved shall be determined by means of 
differential weighing. The gas accumulated in the bag shall be 
analysed by means of the equipment normally used for exhaust

 02017R1151 — EN — 27.07.2017 — 001.003 — 552  
4.2.1.2. General requirements  
4.2.1.2.1. The sampling probe for the test gas flow for particulate shall be 
arranged within the dilution tunnel so that a representative sample 
gas flow can be taken from the homogeneous air/exhaust mixture 
and shall be upstream of a heat exchanger (if any).  
4.2.1.2.2. The particulate sample flow rate shall be proportional to the total 
mass flow of diluted exhaust gas in the dilution tunnel to within a 
tolerance of ± 5 per cent of the particulate sample flow rate. The 
verification of the proportionality of the particulate sampling shall 
be made during the commissioning of the system and as required 
by the approval authority.  
4.2.1.2.3. The sampled dilute exhaust gas shall be maintained at a 
temperature above 20 °C and below 52 °C within 20 cm 
upstream or downstream of the particulate sampling filter face. 
Heating or insulation of components of the particulate sampling 
system to achieve this is permitted.  
In the event that the 52 °C limit is exceeded during a test where 
periodic regeneration event does not occur, the CVS flow rate 
shall be increased or double dilution shall be applied (assuming 
that the CVS flow rate is already sufficient so as not to cause 
condensation within the CVS, sample bags or analytical system).  
4.2.1.2.4. The particulate sample shall be collected on a single filter 
mounted within a holder in the sampled dilute exhaust gas flow.  
4.2.1.2.5. All parts of the dilution system and the sampling system from the 
exhaust pipe up to the filter holder that are in contact with raw 
and diluted exhaust gas shall be designed to minimise deposition 
or alteration of the particulate. All parts shall be made of elec ­
trically conductive materials that do not react with exhaust gas 
components, and shall be electrically grounded to prevent elec ­
trostatic effects.  
4.2.1.2.6. If it is not possible to compensate for variations in the flow rate, 
provision shall be made for a heat exchanger and a temperature 
control device as specified in paragraphs 3.3.5.1. or 3.3.6.4.2. of 
this Sub-Annex, so as to ensure that the flow rate in the system is 
constant and the sampling rate accordingly proportional.  
4.2.1.2.7. Temperatures required for the measurement of PM shall be 
measured with an accuracy of ± 1 °C and a response time (t  10 
– t 90 ) of 15 seconds or less.  
4.2.1.2.8. The sample flow from the dilution tunnel shall be measured with 
an accuracy of ± 2.5 per cent of reading or ± 1.5 per cent full 
scale, whichever is the least.  
The accuracy specified above of the sample flow from the CVS 
tunnel is also applicable where double dilution is used. 
Consequently, the measurement and control of the secondary 
dilution air flow and diluted exhaust flow rates through the filter 
shall be of a higher accuracy.  
4.2.1.2.9. All data channels required for the measurement of PM shall be 
logged at a frequency of 1 Hz or faster. Typically these would 
include:  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 553  
(a) Diluted exhaust temperature at the particulate sampling filter;  
(b) Sampling flow rate;  
(c) Secondary dilution air flow rate (if secondary dilution is 
used);  
(d) Secondary dilution air temperature (if secondary dilution is 
used).  
4.2.1.2.10. For double dilution systems, the accuracy of the diluted exhaust 
transferred from the dilution tunnel V  ep defined in paragraph 
3.3.2. of Sub-Annex 7 in the equation is not measured directly 
but determined by differential flow measurement.  
The accuracy of the flow meters used for the measurement and 
control of the double diluted exhaust passing through the 
particulate sampling filters and for the measurement/control of 
secondary dilution air shall be sufficient so that the differential 
volume V  ep shall meet the accuracy and proportional sampling 
requirements specified for single dilution.  
The requirement that no condensation of the exhaust gas occur in 
the CVS dilution tunnel, diluted exhaust flow rate measurement 
system, CVS bag collection or analysis systems shall also apply in 
the case that double dilution systems are used.  
4.2.1.2.11. Each flow meter used in a particulate sampling and double 
dilution system shall be subjected to a linearity verification as 
required by the instrument manufacturer.

4.2.1.3.1.1. The sample probe shall deliver the particle size classification 
performance specified in paragraph 4.2.1.3.1.4. of this Sub- 
Annex. It is recommended that this performance be achieved by 
the use of a sharp-edged, open-ended probe facing directly into the 
direction of flow plus a pre-classifier (cyclone impactor, etc.). An 
appropriate sample probe, such as that indicated in Figure A5/11, 
may alternatively be used provided it achieves the pre-classifi ­
cation performance specified in paragraph 4.2.1.3.1.4. of this 
Sub-Annex.  
4.2.1.3.1.2. The sample probe shall be installed at least 10 tunnel diameters 
downstream of the exhaust gas inlet to the tunnel and have an 
internal diameter of at least 8 mm.  
If more than one simultaneous sample is drawn from a single

identical sub-flows to avoid sampling artefacts.  
If multiple probes are used, each probe shall be sharp-edged, 
open-ended and facing directly into the direction of flow. Probes

of reducing particles in the most penetrating particle size of the 
filter material by ≥ 99,95 per cent, or through a HEPA filter of at 
least class H13 of EN 1822:2009. The dilution air may optionally 
be charcoal-scrubbed before being passed to the HEPA filter. It is 
recommended that an additional coarse particle filter be situated 
before the HEPA filter and after the charcoal scrubber, if used.  
4.2.1.3.3.1.2. The secondary dilution air should be injected into the PTT as 
close to the outlet of the diluted exhaust from the dilution 
tunnel as possible.  
4.2.1.3.3.1.3. The residence time from the point of secondary diluted air 
injection to the filter face shall be at least 0.25 seconds, but no 
longer than 5 seconds.  
4.2.1.3.3.1.4. If the double diluted sample is returned to the CVS, the location 
of the sample return shall be selected so that it does not interfere 
with the extraction of other samples from the CVS.  
4.2.1.3.4. Sample pump and flow meter  
4.2.1.3.4.1. The sample gas flow measurement unit shall consist of pumps, gas 
flow regulators and flow measuring units.  
4.2.1.3.4.2. The temperature of the gas flow in the flow meter may not 
fluctuate by more than ± 3 °C except:  
(a) When the sampling flow meter has real time monitoring and 
flow control operating at a frequency of 1 Hz or faster;  
(b) During regeneration tests on vehicles equipped with period ­
ically regenerating after-treatment devices.  
Should the volume of flow change unacceptably as a result of

4.2.1.3.5.2. For a given test, the gas filter face velocity shall be set to an initial 
value within the range 20 cm/s to 105 cm/s and shall be set at the 
start of the test so that 105 cm/s will not be exceeded when the 
dilution system is being operated with sampling flow proportional 
to CVS flow rate.  
4.2.1.3.5.3. Fluorocarbon coated glass fibre filters or fluorocarbon membrane 
filters shall be used.  
All filter types shall have a 0,3 μm DOP (di-octylphthalate) or

velocity of 5,33 cm/s measured according to one of the following 
standards:

possible) during all filter conditioning and weighing.  
(b) Humidity shall be maintained at a dew point of less than 
10.5 °C and a relative humidity of 45 per cent ± 8 per cent.  
(c) Limited deviations from weighing chamber (or room) 
temperature and humidity specifications shall be permitted

specified conditions are permitted.  
4.2.2.2. Linear response of an analytical balance  
The analytical balance used to determine the filter weight shall 
meet the linearity verification criteria of Table A5/1 applying a

determination r  2 
Particulate Balance  ≤ 1 μg 0,99 – 1,01  ≤ 1per cent max  ≥ 0,998  
4.2.2.3. Elimination of static electricity effects  
The effects of static electricity shall be nullified. This may be 
achieved by grounding the balance through placement upon an 
antistatic mat and neutralization of the particulate sampling 
filters prior to weighing using a polonium neutraliser or a 
device of similar effect. Alternatively, nullification of static 
effects may be achieved through equalization of the static charge.  
4.2.2.4. Buoyancy correction  
The sample and reference filter weights shall be corrected for their 
buoyancy in air. The buoyancy correction is a function of 
sampling filter density, air density and the density of the 
balance calibration weight, and does not account for the 
buoyancy of the particulate matter itself.  
If the density of the filter material is not known, the following 
densities shall be used:  
(a) PTFE coated glass fibre filter: 2 300 kg/m  3 ; 
(b) PTFE membrane filter: 2 144 kg/m  3 ; 
(c) PTFE membrane filter with polymethylpentene support ring: 
920 kg/m  3 . 
For stainless steel calibration weights, a density of 8 000 kg/m  3 
shall be used. If the material of the calibration weight is different, 
its density shall be known and be used. International Recommen ­
dation OIML R 111-1 Edition 2004(E) (or equivalent) from Inter ­
national Organization of Legal Metrology on calibration weights 
should be followed.  
The following equation shall be used:  
m f ¼ m uncorr Ü A 
1 Ä ρ a 
ρ w 
1 Ä ρ a 
ρ f ! 
where:  
Pe f is the corrected particulate sample mass, mg;  
Pe uncorr  is the uncorrected particulate sample mass, mg;  
ρ a is the density of the air, kg/m  3 ; 
ρ w is the density of balance calibration weight, kg/m  3 ; ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 558  
ρ f is the density of the particulate sampling filter, kg/m  3 . 
The density of the air ρ a shall be calculated using the following 
equation:  
ρ a ¼ p b Ü M mix 
R Ü T a 
p b is the total atmospheric pressure, kPa;  
T a is the air temperature in the balance environment, 
Kelvin (K);  
M mix is the molar mass of air in a balanced environment, 
28,836 g mol  –1 ; 
R is the molar gas constant, 8,3144 J mol  –1 K –1 .

4.3.1.1.1. The particle sampling system shall consist of a probe or sampling 
point extracting a sample from a homogenously mixed flow in a

the exit of the PCF at the volumetric flow rate selected for particle 
sampling.  
A sample probe acting as an appropriate size-classification device,

5.2.2.1. The analyser linearization curve shall be established by at least 
five calibration points spaced as uniformly as possible. The 
nominal concentration of the calibration gas of the highest concen ­
tration shall be not less than 80 per cent of the full scale.  
5.2.2.2. The calibration gas concentration required may be obtained by 
means of a gas divider, diluting with purified N  2 or with 
purified synthetic air.  
5.2.2.3. The linearization curve shall be calculated by the least squares 
method. If the resulting polynomial degree is greater than 3, the 
number of calibration points shall be at least equal to this poly ­
nomial degree plus 2.  
5.2.2.4. The linearization curve shall not differ by more than ± 2 per cent 
from the nominal value of each calibration gas.  
5.2.2.5. From the trace of the linearization curve and the linearization 
points it is possible to verify that the calibration has been 
carried out correctly. The different characteristic parameters of 
the analyser shall be indicated, particularly:  
(a) Analyser and gas component;  
(b) Range;  
(c) Date of linearisation.  
5.2.2.6. If the approval authority is satisfied that alternative technologies 
(e.g. computer, electronically controlled range switch, etc.) give 
equivalent accuracy, these alternatives may be used.  
5.3. Analyser zero and calibration verification procedure  
5.3.1. Each normally used operating range shall be checked prior to each 
analysis in accordance with paragraphs 5.3.1.1. and 5.3.1.2. of this 
Sub-Annex  
5.3.1.1. The calibration shall be checked by use of a zero gas and by use of a 
calibration gas according to paragraph 1.2.14.2.3. of Sub-Annex 6,  
5.3.1.2. After testing, zero gas and the same calibration gas shall be used for

 02017R1151 — EN — 27.07.2017 — 001.003 — 565  
5.4.3.1. The response factor R  f for a particular hydrocarbon compound is 
the ratio of the FID C  1 reading to the gas cylinder concentration, 
expressed as ppm C  1 . 
The concentration of the test gas shall be at a level to give a 
response of approximately 80 per cent of full-scale deflection 
for the operating range. The concentration shall be known to an 
accuracy of ± 2 per cent in reference to a gravimetric standard 
expressed in volume. In addition, the gas cylinder shall be precon ­
ditioned for 24 hours at a temperature between 20 and 30 °C.  
5.4.3.2. Response factors shall be determined when introducing an 
analyser into service and at major service intervals thereafter.

are: 
Propylene and purified air:  0,90 < R f< 1,10  
Toluene and purified air:  0,90 < R f< 1,10  
These are relative to an R  f of 1,00 for propane and purified air.  
5.5. NO  x converter efficiency test procedure  
5.5.1. Using the test set up as shown in Figure A5/15 and the procedure 
described below, the efficiency of converters for the conversion of 
NO  2 into NO shall be tested by means of an ozonator as follows:  
5.5.1.1. The analyser shall be calibrated in the most common operating 
range following the manufacturer's specifications using zero and 
calibration gas (the NO content of which shall amount to approxi ­
mately 80 per cent of the operating range and the NO  2 concen­
tration of the gas mixture shall be less than 5 per cent of the NO 
concentration). The NO  x analyser shall be in the NO mode so that 
the calibration gas does not pass through the converter. The 
indicated concentration shall be included in all relevant test sheets.  
5.5.1.2. Via a T-fitting, oxygen or synthetic air shall be added 
continuously to the calibration gas flow until the concentration 
indicated is approximately 10 per cent less than the indicated 
calibration concentration given in paragraph 5.5.1.1. of this Sub- 
Annex. The indicated concentration (c) shall be included in all 
relevant test sheets. The ozonator shall be kept deactivated 
throughout this process.  
5.5.1.3. The ozonator shall now be activated to generate enough ozone to 
bring the NO concentration down to 20 per cent (minimum 10 per 
cent) of the calibration concentration given in paragraph 5.5.1.1. 
of this Sub-Annex. The indicated concentration (d) shall be 
included all relevant test sheets.  
5.5.1.4. The NO  x analyser shall be subsequently switched to the NO  x 
mode, whereby the gas mixture (consisting of NO, NO  2 , O  2 and 
N 2 ) now passes through the converter. The indicated concentration 
(a) shall be included in all relevant test sheets.  
5.5.1.5. The ozonator shall now be deactivated. The mixture of gases 
described in paragraph 5.5.1.2. of this Sub-Annex shall pass 
through the converter into the detector. The indicated concen ­
tration (b) shall be included in all relevant test sheets.  ▼B

NO  x converter efficiency test configuration
  
5.5.1.6. With the ozonator deactivated, the flow of oxygen or synthetic air 
shall be shut off. The NO  2 reading of the analyser shall then be no 
more than 5 per cent above the figure given in paragraph 5.5.1.1. 
of this Sub-Annex.  
5.5.1.7. The per cent efficiency of the NO  x converter shall be calculated 
using the concentrations a, b, c and d determined in paragraphs 
5.5.1.2. to 5.5.1.5. of this Sub-Annex inclusive using the 
following equation:  
Efficiency ¼ Í 
1 þ a Ä b 
c Ä d Î 
Ü 100 
5.5.1.7.1. The efficiency of the converter shall not be less than 95 per cent. 
The efficiency of the converter shall be tested in the frequency 
defined in Table A5/3.  
5.6. Calibration of the microgram balance  
5.6.1. The calibration of the microgram balance used for particulate 
sampling filter weighing shall be traceable to a national or inter ­
national standard. The balance shall comply with the linearity 
requirements given in paragraph 4.2.2.2. of this Sub-Annex. The 
linearity verification shall be performed at least every 12 months 
or whenever a system repair or change is made that could 
influence the calibration.  
5.7. Calibration and validation of the particle sampling system  
Examples of calibration/validation methods are available at:

pmpFCP.html  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 567  
5.7.1. Calibration of the PNC  
5.7.1.1. The approval authority shall ensure the existence of a calibration 
certificate for the PNC demonstrating compliance with a traceable 
standard within a 13-month period prior to the emissions test. 
Between calibrations either the counting efficiency of the PNC 
shall be monitored for deterioration or the PNC wick shall be 
routinely changed every 6 months. See Figures A5/16 and 
A5/17. PNC counting efficiency may be monitored against a 
reference PNC or against at least two other measurement PNCs. 
If the PNC reports particle number concentrations within ± 10 per 
cent of the arithmetic average of the concentrations from the 
reference PNC, or a group of two or more PNCs, the PNC shall 
subsequently be considered stable, otherwise maintenance of the 
PNC is required. Where the PNC is monitored against two or 
more other measurement PNCs, it is permitted to use a 
reference vehicle running sequentially in different test cells each 
with its own PNC.

Extended PNC annual sequence (in the case that a full PNC calibration is delayed)
  
5.7.1.2. The PNC shall also be recalibrated and a new calibration certifi ­
cate issued following any major maintenance.  
5.7.1.3. Calibration shall be traceable to a national or international 
standard calibration method by comparing the response of the 
PNC under calibration with that of:  
(a) A calibrated aerosol electrometer when simultaneously 
sampling electrostatically classified calibration particles; or  
(b) A second PNC that has been directly calibrated by the method 
described above.  
5.7.1.3.1. In paragraph 5.7.1.3. (a) of this Sub-Annex, calibration shall be 
undertaken using at least six standard concentrations spaced as 
uniformly as possible across the PNC’s measurement range.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 568  
5.7.1.3.2. In paragraph 5.7.1.3. (b) of this Sub-Annex, calibration shall be 
undertaken using at least six standard concentrations across the 
PNC’s measurement range. At least 3 points shall be at concen ­
trations below 1,000 per cm  3 , the remaining concentrations shall 
be linearly spaced between 1,000 per cm  3 and the maximum of 
the PNC’s range in single particle count mode.  
5.7.1.3.3. In paragraphs 5.7.1.3.(a) and 5.7.1.3.(b) of this Sub-Annex, the 
selected points shall include a nominal zero concentration 
point produced by attaching HEPA filters of at least class H13 
of EN 1822:2008, or equivalent performance, to the inlet of each 
instrument. With no calibration factor applied to the PNC under 
calibration, measured concentrations shall be within ± 10 per cent 
of the standard concentration for each concentration, with the 
exception of the zero point, otherwise the PNC under calibration 
shall be rejected. The gradient from a linear least squares 
regression of the two data sets shall be calculated and recorded. 
A calibration factor equal to the reciprocal of the gradient shall be 
applied to the PNC under calibration. Linearity of response is 
calculated as the square of the Pearson product moment 
correlation coefficient (r) of the two data sets and shall be equal 
to or greater than 0.97. In calculating both the gradient and r  2 , the 
linear regression shall be forced through the origin (zero concen ­
tration on both instruments).  
5.7.1.4. Calibration shall also include a check, according to the 
requirements of paragraph 4.3.1.3.4.(h) of this Sub-Annex, on 
the PNC’s detection efficiency with particles of 23 nm electrical 
mobility diameter. A check of the counting efficiency with 41 nm 
particles is not required.  
5.7.2. Calibration/validation of the VPR  
5.7.2.1. Calibration of the VPR’s particle concentration reduction factors 
across its full range of dilution settings, at the instrument’s fixed 
nominal operating temperatures, shall be required when the unit is 
new and following any major maintenance. The periodic vali ­
dation requirement for the VPR’s particle concentration 
reduction factor is limited to a check at a single setting, typical 
of that used for measurement on particulate filter-equipped 
vehicles. The approval authority shall ensure the existence of a 
calibration or validation certificate for the VPR within a 6-month 
period prior to the emissions test. If the VPR incorporates 
temperature monitoring alarms, a 13 month validation interval is 
permitted.  
It is recommended that the VPR is calibrated and validated as a 
complete unit.  
The VPR shall be characterised for particle concentration 
reduction factor with solid particles of 30, 50 and 100 nm elec ­
trical mobility diameter. Particle concentration reduction factors 
f r (d) for particles of 30 nm and 50 nm electrical mobility 
diameters shall be no more than 30 per cent and 20 per cent 
higher respectively, and no more than 5 per cent lower than that 
for particles of 100 nm electrical mobility diameter. For the 
purposes of validation, the arithmetic average of the particle 
concentration reduction factor shall be within ± 10 per cent of 
the arithmetic average particle concentration reduction factor  f r 
determined during the primary calibration of the VPR.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 569  
5.7.2.2. The test aerosol for these measurements shall be solid particles of 
30, 50 and 100 nm electrical mobility diameter and a minimum 
concentration of 5 000 particles per cm  3 at the VPR inlet. As an 
option, a polydisperse aerosol with an electrical mobility median 
diameter of 50 nm may be used for validation. The test aerosol 
shall be thermally stable at the VPR operating temperatures. 
Particle number concentrations shall be measured upstream and 
downstream of the components.  
The particle concentration reduction factor for each monodisperse 
particle size, f  r (d i ), shall be calculated using the following 
equation:  
f r ðd i Þ ¼ N in ðd i Þ 
N out ðd i Þ 
where:  
N in (d i ) is the upstream particle number concentration for 
particles of diameter d  i ; 
N out (d i ) is the downstream particle number concentration for 
particles of diameter d  i ; 
d i is the particle electrical mobility diameter (30, 50 or 
100 nm).  
N in (d i ) and N  out (d i ) shall be corrected to the same conditions.  
The arithmetic average particle concentration reduction factor  f r at 
a given dilution setting shall be calculated using the following 
equation:  
f r ¼ f r ð30nmÞ þ f r ð50nmÞ þ f r ð100nmÞ 
3 
Where a polydisperse 50 nm aerosol is used for validation, the 
arithmetic average particle concentration reduction factor  f v at the 
dilution setting used for validation shall be calculated using the 
following equation:  
f v ¼ N in 
N out 
where:  
N in is the upstream particle number concentration;  
N out is the downstream particle number concentration.  
5.7.2.3. The VPR shall demonstrate greater than 99.0 per cent removal of 
tetracontane (CH  3 (CH  2 ) 38 CH  3 ) particles of at least 30 nm elec ­
trical mobility diameter with an inlet concentration ≥ 10 000 
per cm  3 when operated at its minimum dilution setting and manu ­
facturers recommended operating temperature.  ▼B

5.7.3. PN measurement system check procedures  
5.7.3.1. On a monthly basis, the flow into the PNC shall have a measured 
value within 5 per cent of the PNC nominal flow rate when 
checked with a calibrated flow meter.  
5.8. Accuracy of the mixing device  
In the case that a gas divider is used to perform the calibrations as 
defined in paragraph 5.2. of this Sub-Annex, the accuracy of the 
mixing device shall be such that the concentrations of the diluted 
calibration gases may be determined to within ± 2 per cent. A 
calibration curve shall be verified by a mid-span check as 
described in paragraph 5.3. of this Sub-Annex. A calibration gas 
with a concentration below 50 per cent of the analyser range shall 
be within 2 per cent of its certified concentration.

Sub-Annex 6  
Type 1 test procedures and test conditions  
1. Test procedures and test conditions  
1.1 Description of tests  
1.1.1. The Type 1 test is used to verify the emissions of gaseous 
compounds, particulate matter, particle number, CO  2 mass 
emission, fuel consumption, electric energy consumption and 
electric ranges over the applicable WLTP test cycle.  
1.1.1.1. The tests shall be carried out according to the method described in 
paragraph 1.2. of this Sub-Annex or paragraph 3. of Sub-Annex 8 
for pure electric, hybrid electric and compressed hydrogen fuel 
cell hybrid vehicles. Exhaust gases, particulate matter and 
particles shall be sampled and analysed by the prescribed methods.  
1.1.2. The number of tests shall be determined according to the 
flowchart in Figure A6/1. The limit value is the maximum 
allowed value for the respective criteria pollutant as specified in 
Annex I of Regulation (EC) No 715/2007.  
1.1.2.1. The flowchart in Figure A6/1 shall be applicable only to the whole 
applicable WLTP test cycle and not to single phases.  
1.1.2.2. The test results shall be the values after the REESS energy 
change-based, Ki and ATCT corrections are applied.  
1.1.2.3. Determination of total cycle values  
1.1.2.3.1. If during any of the tests a criteria emissions limit is exceeded, the 
vehicle shall be rejected.  
1.1.2.3.2. Depending on the vehicle type, the manufacturer shall declare as 
applicable the total cycle value of the CO  2 mass emission, the 
electric energy consumption, fuel consumption for NOVC-FCHV 
as well as PER and AER according to Table A6/1.  
1.1.2.3.3. The declared value of the electric energy consumption for 
OVC-HEVs under charge-depleting operating condition shall not 
be determined according to Figure A6/1. It shall be taken as the 
type approval value if the declared CO  2 value is accepted as the 
approval value. If that is not the case, the measured value of 
electric energy consumption shall be taken as the type approval 
value.  
1.1.2.3.4. If after the first test all criteria in row 1 of the applicable Table 
A6/2 are fulfilled, all values declared by the manufacturer shall be 
accepted as the type approval value. If any one of the criteria in 
row 1 of the applicable Table A6/2 is not fulfilled, a second test 
shall be performed with the same vehicle.  
1.1.2.3.5. After the second test, the arithmetic average results of the two 
tests shall be calculated. If all criteria in row 2 of the applicable 
Table A6/2 are fulfilled by these arithmetic average results, all 
values declared by the manufacturer shall be accepted as the  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 573  
type approval value. If any one of the criteria in row 2 of the 
applicable Table A6/2 is not fulfilled, a third test shall be 
performed with the same vehicle.  
1.1.2.3.6. After the third test, the arithmetic average results of the three tests 
shall be calculated. For all parameters which fulfil the 
corresponding criterion in row 3 of the applicable Table A6/2, 
the declared value shall be taken as the type approval value. 
For any parameter which does not fulfil the corresponding 
criterion in row 3 of the applicable Table A6/2, the arithmetic 
average result shall be taken as the type approval value.  
1.1.2.3.7. In the case that any one of the criterion of the applicable Table 
A6/2 is not fulfilled after the first or second test, at the request of 
the manufacturer and with the approval of the approval authority, 
the values may be re-declared as higher values for emissions or 
consumption, or as lower values for electric ranges, in order to 
reduce the required number of tests for type approval.  
1.1.2.3.8. dCO2  1 , dCO2  2 and dCO2  3 determination.  
1.1.2.3.8.1. Without prejudice to the requirement of paragraph 1.1.2.3.8.2., the 
following values for dCO2  1 , dCO2  2 and dCO2  3 shall be used in 
relation to the criteria for the number of tests in Table A6/2:  
dCO2  1 = 0,990  
dCO2  2 = 0,995  
dCO2  3 = 1,000  
1.1.2.3.8.2. If the charge depleting Type 1 test for OVC-HEVs consists of two 
or more applicable WLTP test cycles and the dCO2x value is 
below 1,0, the dCO2x value shall be replaced by 1,0.  
1.1.2.3.9. In the case that a test result or an average of test results was taken 
and confirmed as the type approval value, this result shall be 
referred to as ‘declared value’ for further calculations.

1.1.2.4. Determination of phase-specific values  
1.1.2.4.1. Phase-specific value for CO  2 
1.1.2.4.1.1. After the total cycle declared value of the CO  2 mass emission is 
accepted, the arithmetic average of the phase-specific values of the 
test results in g/km shall be multiplied by the adjustment factor 
CO2_AF to compensate for the difference between the declared 
value and the test results. This corrected value shall be the type 
approval value for CO  2 . 
CO2_AF ¼ Declared value 
Phase combined value  
where: 
Phase combined value  ¼ CO2  ave  L Ü D L þ CO2  ave  M Ü D M þ CO2  ave  H Ü D H þ CO2  ave  exH Ü D exH 
D L þ D M þ D H þ D exH 
where:  
CO2  ave  L is the arithmetic average CO  2 mass emission result for 
the L phase test result(s), g/km;  
CO2  ave  M is the arithmetic average CO  2 mass emission result for 
the M phase test result(s), g/km;  
CO2  ave  H is the arithmetic average CO  2 mass emission result for 
the H phase test result(s), g/km;  
CO2  ave  exH is the arithmetic average CO  2 mass emission result for 
the exH phase test result(s), g/km;  
D L is theoretical distance of phase L, km;  
D M is theoretical distance of phase M, km;  
D H is theoretical distance of phase H, km;  
D exH is theoretical distance of phase exH, km.  
1.1.2.4.1.2. If the total cycle declared value of the CO  2 mass emission is not 
accepted, the type approval phase-specific CO  2 mass emission 
value shall be calculated by taking the arithmetic average of the 
all test results for the respective phase.  
1.1.2.4.2. Phase-specific values for fuel consumption  
1.1.2.4.2.1. The fuel consumption value shall be calculated by the phase- 
specific CO  2 mass emission using the equations in paragraph 
1.1.2.4.1. of this Sub-Annex and the arithmetic average of the 
emissions.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 577  
1.1.2.4.3. Phase-specific value for electric energy consumption, PER and 
AER.  
1.1.2.4.3.1. The phase-specific electric energy consumption and the phase- 
specific electric ranges are calculated by taking the arithmetic 
average of the phase specific values of the test result(s), without 
an adjustment factor.  
1.2. Type 1 test conditions  
1.2.1. Overview  
1.2.1.1. The Type 1 test shall consist of prescribed sequences of dyna ­
mometer preparation, fuelling, soaking, and operating conditions.  
1.2.1.2. The Type 1 test shall consist of vehicle operation on a chassis 
dynamometer on the applicable WLTC for the interpolation 
family. A proportional part of the diluted exhaust emissions 
shall be collected continuously for subsequent analysis using a 
constant volume sampler.  
1.2.1.3. Background concentrations shall be measured for all compounds 
for which dilute mass emissions measurements are conducted. For 
exhaust emissions testing, this requires sampling and analysis of 
the dilution air.  
1.2.1.3.1. Background particulate measurement  
1.2.1.3.1.1. Where the manufacturer requests subtraction of either dilution air 
or dilution tunnel background particulate mass from emissions 
measurements, these background levels shall be determined 
according to the procedures listed in paragraphs 1.2.1.3.1.1.1. to 
1.2.1.3.1.1.3. inclusive of this Sub-Annex.  
1.2.1.3.1.1.1. The maximum permissible background correction shall be a mass 
on the filter equivalent to 1 mg/km at the flow rate of the test.  
1.2.1.3.1.1.2. If the background exceeds this level, the default figure of 1 
mg/km shall be subtracted.  
1.2.1.3.1.1.3. Where subtraction of the background contribution gives a negative 
result, the background level shall be considered to be zero.  
1.2.1.3.1.2. Dilution air background particulate mass level shall be determined 
by passing filtered dilution air through the particulate background 
filter. This shall be drawn from a point immediately downstream 
of the dilution air filters. Background levels in g/m  3 shall be 
determined as a rolling arithmetic average of at least 14 
measurements with at least one measurement per week.  
1.2.1.3.1.3. Dilution tunnel background particulate mass level shall be 
determined by passing filtered dilution air through the particulate 
background filter. This shall be drawn from the same point as the 
particulate matter sample. Where secondary dilution is used for the 
test, the secondary dilution system shall be active for the purposes 
of background measurement. One measurement may be performed 
on the day of test, either prior to or after the test.  
1.2.1.3.2. Background particle number determination  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 578  
1.2.1.3.2.1. Where a manufacturer requests a background correction, these 
background levels shall be determined as follows:  
1.2.1.3.2.1.1. The background value may be either calculated or measured. The 
maximum permissible background correction shall be related to 
the maximum allowable leak rate of the particle number 
measurement system (0,5 particles per cm  3 ) scaled from the 
particle concentration reduction factor, PCRF, and the CVS flow 
rate used in the actual test;  
1.2.1.3.2.1.2. Either the approval authority or the manufacturer may request that 
actual background measurements are used instead of calculated 
ones.  
1.2.1.3.2.1.3. Where subtraction of the background contribution gives a negative 
result, the PN result shall be considered to be zero.  
1.2.1.3.2.2. Dilution air background particle number level shall be determined 
by sampling filtered dilution air. This shall be drawn from a point 
immediately downstream of the dilution air filters into the PN 
measurement system. Background levels in particles per cm  3 
shall be determined as a rolling arithmetic average of least 14 
measurements with at least one measurement per week.  
1.2.1.3.2.3. Dilution tunnel background particle number level shall be 
determined by sampling filtered dilution air. This shall be drawn 
from the same point as the PN sample. Where secondary dilution 
is used for the test the secondary dilution system shall be active 
for the purposes of background measurement. One measurement 
may be performed on the day of test, either prior to or after the 
test using the actual PCRF and the CVS flow rate utilised during 
the test.  
1.2.2. General test cell equipment  
1.2.2.1. Parameters to be measured  
1.2.2.1.1. The following temperatures shall be measured with an accuracy of 
± 1,5 °C:  
(a) Test cell ambient air;  
(b) Dilution and sampling system temperatures as required for 
emissions measurement systems defined in Sub-Annex 5.  
1.2.2.1.2. Atmospheric pressure shall be measurable with a resolution of ± 
0,1 kPa.  
1.2.2.1.3. Specific humidity H shall be measurable with a resolution of ± 1 g 
H 2 O/kg dry air.  
1.2.2.2. Test cell and soak area  
1.2.2.2.1. Test cell  
1.2.2.2.1.1. The test cell shall have a temperature set point of 23 °C. The 
tolerance of the actual value shall be within ± 5 °C. The air 
temperature and humidity shall be measured at the test cell’s 
cooling fan outlet at a minimum frequency of 1 Hz. For the 
temperature at the start of the test, see paragraph 1.2.8.1. in 
Sub-Annex 6.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 579  
1.2.2.2.1.2. The specific humidity H of either the air in the test cell or the 
intake air of the engine shall be such that:  
5,5 Ï H Ï 12,2 ðg H  2 O=kg dry airÞ 
1.2.2.2.1.3. Humidity shall be measured continuously at a minimum frequency 
of 1 Hz.  
1.2.2.2.2. Soak area  
The soak area shall have a temperature set point of 23 °C and the 
tolerance of the actual value shall be within ± 3 °C on a 5 minute 
running arithmetic average and shall not show a systematic 
deviation from the set point. The temperature shall be measured 
continuously at a minimum frequency of 1 Hz.  
1.2.3. Test vehicle  
1.2.3.1. General  
The test vehicle shall conform in all its components with the 
production series, or, if the vehicle is different from the production 
series, a full description shall be included in all relevant test 
reports. In selecting the test vehicle, the manufacturer and 
approval authority shall agree which vehicle model is representa ­
tive for the interpolation family.  
For the measurement of emissions, the road load as determined 
with test vehicle H shall be applied. In the case of a road load 
matrix family, for the measurement of emissions, the road load as 
calculated for vehicle H  M according to paragraph 5.1. of Sub- 
Annex 4 shall be applied.  
If at the request of the manufacturer the interpolation method is 
used (see paragraph 3.2.3.2. of Sub-Annex 7), an additional 
measurement of emissions shall be performed with the road load 
as determined with test vehicle L. Tests on vehicles H and L 
should be performed with the same test vehicle and shall be 
tested with the shortest final transmission ratio within the inter ­
polation family. In the case of a road load matrix family, an 
additional measurement of emissions shall be performed with 
the road load as calculated for vehicle L  M according to 
paragraph 5.1. of Sub-Annex 4.  
1.2.3.2. CO  2 interpolation range  
The interpolation method shall only be used if the difference in 
CO  2 between test vehicles L and H is between a minimum of 5 
and a maximum of 30 g/km or 20 per cent of the CO  2 emissions 
from vehicle H, whichever value is the lower.  
At the request of the manufacturer and with approval of the 
approval authority, the interpolation line may be extrapolated to 
a maximum of 3 g/km above the CO  2 emission of vehicle H 
and/or below the CO  2 emission of vehicle L. This extension is 
valid only within the absolute boundaries of the interpolation 
range specified above.  
This paragraph is not applicable for the difference in CO  2 between 
vehicles H  M and L  M of a road load matrix family.  
1.2.3.3. Run-in  
The vehicle shall be presented in good technical condition. It shall 
have been run-in and driven between 3 000 and 15 000 km before 
the test. The engine, transmission and vehicle shall be run-in in 
accordance with the manufacturer’s recommendations.  ▼B

1.2.4.2.2. The vehicle’s dynamometer operation mode, if any, shall be 
activated by using the manufacturer's instruction (e.g. using 
vehicle steering wheel buttons in a special sequence, using the 
manufacturer’s workshop tester, removing a fuse).  
The manufacturer shall provide the approval authority a list of the 
deactivated devices and justification for the deactivation. The 
dynamometer operation mode shall be approved by the approval 
authority and the use of a dynamometer operation mode shall be 
included in all relevant test reports.  
1.2.4.2.3. The dynamometer operation mode shall not activate, modulate, 
delay or deactivate the operation of any part that affects the 
emissions and fuel consumption under the test conditions. Any 
device that affects the operation on a chassis dynamometer shall 
be set to ensure a proper operation.  
1.2.4.2.4. If the test vehicle is tested in a two-wheel drive (2WD) mode, the 
test vehicle shall be tested on a single-axis chassis dynamometer 
which fulfils the requirements according to paragraph 2. of Sub- 
Annex 5. At the request of the manufacturer and with the approval 
of the approval authority, the vehicle may be tested on a dual-axis 
chassis dynamometer.  
1.2.4.2.5. If the test vehicle is tested in a mode which under WLTP 
conditions would enter into partially or permanent four-wheel 
drive (4WD) operation over the applicable cycle, the test vehicle 
shall be tested on a dual-axis chassis dynamometer which fulfils 
the requirements according to paragraph 2.3. of Sub-Annex 5.  
At the request of the manufacturer and with the approval of the 
approval authority, the vehicle may be tested on a single-axis 
chassis dynamometer if the following conditions are met:  
(a) the test vehicle is converted to permanent 2WD operation in 
all test modes;  
(b) the manufacturer provides evidence to the approval authority 
that the CO  2 , fuel consumption and/or electrical energy 
consumption of the converted vehicle is the same or higher 
as for the non-converted vehicle being tested on a dual-axis 
chassis dynamometer.  
1.2.4.3. The vehicle’s exhaust system shall not exhibit any leak likely to 
reduce the quantity of gas collected.  
1.2.4.4. The settings of the powertrain and vehicle controls shall be those 
prescribed by the manufacturer for series production.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 581  
1.2.4.5. Tyres shall be of a type specified as original equipment by the 
vehicle manufacturer. Tyre pressure may be increased by up to 50 
per cent above the pressure specified in paragraph 4.2.2.3. of Sub- 
Annex 4. The same tyre pressure shall be used for the setting of 
the dynamometer and for all subsequent testing. The tyre pressure 
used shall be included in all relevant test reports.  
1.2.4.6. Reference fuel  
1.2.4.6.1. The appropriate reference fuel as defined in Annex IX shall be 
used for testing.  
1.2.4.7. Test vehicle preparation  
1.2.4.7.1. The vehicle shall be approximately horizontal during the test so as 
to avoid any abnormal distribution of the fuel.  
1.2.4.7.2. If necessary, the manufacturer shall provide additional fittings and 
adapters, as required to accommodate a fuel drain at the lowest 
point possible in the tank(s) as installed on the vehicle, and to 
provide for exhaust sample collection.  
1.2.4.7.3. For PM sampling during a test when the regenerating device is in 
a stabilized loading condition (i.e. the vehicle is not undergoing a 
regeneration), it is recommended that the vehicle has completed > 
1/3 of the mileage between scheduled regenerations or that the 
periodically regenerating device has undergone equivalent loading 
off the vehicle.  
1.2.5. Preliminary testing cycles  
1.2.5.1. Preliminary testing cycles may be carried out if requested by the 
manufacturer to follow the speed trace within the prescribed 
limits.  
1.2.6. Test vehicle preconditioning  
1.2.6.1. The fuel tank (or fuel tanks) shall be filled with the specified test 
fuel. If the existing fuel in the fuel tank (or fuel tanks) does not 
meet the specifications contained in paragraph 1.2.4.6. of this Sub- 
Annex, the existing fuel shall be drained prior to the fuel fill. The 
evaporative emission control system shall neither be abnormally 
purged nor abnormally loaded.  
1.2.6.2. REESSs charging  
Before the preconditioning test cycle, the REESSs shall be fully 
charged. At the request of the manufacturer, charging may be 
omitted before preconditioning. The REESSs shall not be 
charged again before official testing.  
1.2.6.3. The test vehicle shall be moved to the test cell and the operations 
listed in paragraphs 1.2.6.3.1. to 1.2.6.3.9. inclusive shall be 
performed.  
1.2.6.3.1. The test vehicle shall be placed, either by being driven or pushed, 
on a dynamometer and operated through the applicable WLTCs.

paragraph 1.2.4.5. of this Sub-Annex.  
1.2.6.3.5. Between the tests on the first gaseous reference fuel and the 
second gaseous reference fuel, for vehicles with positive ignition 
engines fuelled with LPG or NG/biomethane or so equipped that 
they can be fuelled with either petrol or LPG or NG/biomethane, 
the vehicle shall be preconditioned again before the test on the 
second reference fuel.  
1.2.6.3.6. For preconditioning, the applicable WLTC shall be driven. 
Starting the engine and driving shall be performed according to 
paragraph 1.2.6.4. of this Sub-Annex.  
The dynamometer shall be set according to Sub-Annex 4.  
1.2.6.3.7. At the request of the manufacturer or approval authority, ad ­
ditional WLTCs may be performed in order to bring the vehicle 
and its control systems to a stabilized condition.  
1.2.6.3.8. The extent of such additional preconditioning shall be included in 
all relevant test reports.  
1.2.6.3.9. In a test facility in which there may be possible contamination of a 
low particulate emitting vehicle test with residue from a previous 
test on a high particulate emitting vehicle, it is recommended, for 
the purpose of sampling equipment preconditioning, that a 120 
km/h steady state drive cycle of 20 minutes duration be driven 
by a low particulate emitting vehicle. Longer and/or higher speed 
running is permissible for sampling equipment preconditioning if 
required. Dilution tunnel background measurements shall be taken 
after the tunnel preconditioning, and prior to any subsequent 
vehicle testing.  
1.2.6.4. The powertrain start procedure shall be initiated by means of the

e.g. the engine does not start as anticipated or the vehicle displays 
a start error, the test is void, preconditioning tests shall be repeated 
and a new test shall be driven.  
1.2.6.4.2. The cycle starts on initiation of the powertrain start procedure.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 583  
1.2.6.4.3. In the cases where LPG or NG/biomethane is used as a fuel, it is 
permissible that the engine is started on petrol and switched auto ­
matically to LPG or NG/biomethane after a predetermined period 
of time that cannot be changed by the driver.  
1.2.6.4.4. During stationary/idling vehicle phases, the brakes shall be applied 
with appropriate force to prevent the drive wheels from turning.  
1.2.6.4.5. During the test, speed shall be measured against time or collected 
by the data acquisition system at a frequency of not less than 1 Hz 
so that the actual driven speed can be assessed.  
1.2.6.4.6. The distance actually driven by the vehicle shall be included in all 
relevant test sheets for each WLTC phase.  
1.2.6.5. Use of the transmission  
1.2.6.5.1. Manual shift transmission  
The gear shift prescriptions specified in Sub-Annex 2 shall be 
followed. Vehicles tested according to Sub-Annex 8 shall be 
driven according to paragraph 1.5. of that Sub-Annex.  
Vehicles that cannot attain the acceleration and maximum speed 
values required in the applicable WLTC shall be operated with the 
accelerator control fully activated until they once again reach the 
required speed trace. Speed trace violations under these circum ­
stances shall not void a test. Deviations from the driving cycle 
shall be included in all relevant test sheets.

1.2.6.5.2.2. Vehicles equipped with automatic shift transmissions with driver- 
selectable modes shall fulfill the limits of criteria emissions in all 
automatic shift modes used for forward driving. The manufacturer 
shall give appropriate evidence to the approval authority. On the 
basis of technical evidence provided by the manufacturer and with 
the agreement of the approval authority, the dedicated driver- 
selectable modes for very special limited purposes shall not be 
considered (e.g. maintenance mode, crawler mode).  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 584  
1.2.6.5.2.3. The manufacturer shall give evidence to the approval authority of 
the existence of a mode that fulfils the requirements of paragraph 
3.5.9. of this Annex. With the agreement of the approval auth ­
ority, the predominant mode may be used as the only mode for the 
determination of criteria emissions, CO  2 emissions, and fuel 
consumption. Notwithstanding the existence of a predominant 
mode, the criteria emission limits shall be fulfilled in all 
considered automatic shift modes used for forward driving as 
described in paragraph 1.2.6.5.2.2. of this Sub-Annex.  
1.2.6.5.2.4. If the vehicle has no predominant mode or the requested 
predominant mode is not agreed by the approval authority as a 
predominant mode, the vehicle shall be tested in the best case 
mode and worst case mode for criteria emissions, CO  2 emissions, 
and fuel consumption. Best and worst case modes shall be 
identified by the evidence provided on the CO  2 emissions and 
fuel consumption in all modes. CO  2 emissions and fuel 
consumption shall be the arithmetic average of the test results in 
both modes. Test results for both modes shall be included in all 
relevant test reports. Notwithstanding the usage of the best and 
worst case modes for testing, the criteria emission limits shall be 
fulfilled in all automatic shift modes in consideration used for 
forward driving as described in paragraph 1.2.6.5.2.2. of this 
Sub-Annex.

time during the test. Initial engagement shall be done 1 second 
before beginning the first acceleration.  
1.2.6.5.2.6. Vehicles with an automatic transmission with a manual mode shall 
be tested according paragraph 1.2.6.5.2. of this Sub-Annex.  
1.2.6.6. Speed trace tolerances  
The following tolerances shall be permitted between the actual 
vehicle speed and the prescribed speed of the applicable test 
cycles. The tolerances shall not be shown to the driver:

trace within ± 1,0 second of the given point in time;  
(b) Lower limit: 2,0 km/h lower than the lowest point of the trace 
within ± 1,0 second of the given time.  
See Figure A6/2.

1.2.6.8.1. During decelerations of the cycle, the driver shall deactivate the 
accelerator control but shall not manually disengage the clutch 
until the point specified in paragraph 4.(c) of Sub-Annex 2.  
1.2.6.8.1.1. If the vehicle decelerates faster than prescribed by the speed trace, 
the accelerator control shall be operated such that the vehicle 
accurately follows the speed trace.  
1.2.6.8.1.2. If the vehicle decelerates too slowly to follow the intended decel ­
eration, the brakes shall be applied such that it is possible to 
accurately follow the speed trace.

1.2.9. Gaseous sampling  
Gaseous samples shall be collected in bags and the compounds 
analysed at the end of the test or a test phase, or the compounds 
may be analysed continuously and integrated over the cycle.  
1.2.9.1. The following steps shall be taken prior to each test.  
1.2.9.1.1. The purged, evacuated sample bags shall be connected to the

levels.  
1.2.9.1.6. Any electronic integrating device shall be zeroed and may be re- 
zeroed before the start of any cycle phase.  
1.2.9.1.7. For all continuous gas analysers, the appropriate ranges shall be 
selected. These may be switched during a test only if switching is 
performed by changing the calibration over which the digital 
resolution of the instrument is applied. The gains of an analyser’s 
analogue operational amplifiers may not be switched during a test.  
1.2.9.1.8. All continuous gas analysers shall be zeroed and calibrated using 
gases fulfilling the requirements of paragraph 6. of Sub-Annex 5.  
1.2.10. Sampling for PM determination  
1.2.10.1. The steps described in paragraphs 1.2.10.1.1. to 1.2.10.1.2.3. 
inclusive of this Sub-Annex shall be taken prior to each test.  
1.2.10.1.1. Filter selection  
1.2.10.1.1.1. A single particulate sample filter without back-up shall be 
employed for the complete applicable WLTC. In order to accom ­
modate regional cycle variations, a single filter may be employed 
for the first three phases and a separate filter for the fourth phase.  
1.2.10.1.2. Filter preparation  
1.2.10.1.2.1. At least 1 hour before the test, the filter shall be placed in a petri 
dish protecting against dust contamination and allowing air 
exchange, and placed in a weighing chamber (or room) for stabil ­
ization.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 588  
At the end of the stabilization period, the filter shall be weighed 
and its weight shall be included in all relevant test sheets. The 
filter shall subsequently be stored in a closed petri dish or sealed 
filter holder until needed for testing. The filter shall be used within 
8 hours of its removal from the weighing chamber (or room).  
The filter shall be returned to the stabilization room within 1 hour 
after the test and shall be conditioned for at least 1 hour before 
weighing.  
1.2.10.1.2.2. The particulate sample filter shall be carefully installed into the 
filter holder. The filter shall be handled only with forceps or 
tongs. Rough or abrasive filter handling will result in erroneous 
weight determination. The filter holder assembly shall be placed in 
a sample line through which there is no flow.  
1.2.10.1.2.3. It is recommended that the microbalance be checked at the start of 
each weighing session, within 24 hours of the sample weighing, 
by weighing one reference item of approximately 100 mg. This 
item shall be weighed three times and the arithmetic average result 
included in all relevant test sheets. If the arithmetic average result 
of the weighings is ± 5 μg of the result from the previous 
weighing session, the weighing session and balance are considered 
valid.

Sub-Annex.  
1.2.11.1.2.1. A leak check, using a filter of appropriate performance attached to 
the inlet of the entire PN measurement system, VPR and PNC, 
shall report a measured concentration of less than 0.5 particles per 
cm 3 . 
1.2.11.1.2.2. Each day, a zero check on the PNC, using a filter of appropriate 
performance at the PNC inlet, shall report a concentration of ≤ 0,2 
particles per cm  3 . Upon removal of the filter, the PNC shall show 
an increase in measured concentration to at least 100 particles per 
cm 3 when sampling ambient air and a return to ≤ 0.2 particles per 
cm 3 on replacement of the filter.  
1.2.11.1.2.3. It shall be confirmed that the measurement system indicates that 
the evaporation tube, where featured in the system, has reached its 
correct operating temperature.  
1.2.11.1.2.4. It shall be confirmed that the measurement system indicates that 
the diluter PND  1 has reached its correct operating temperature.  
1.2.12. Sampling during the test  
1.2.12.1. The dilution system, sample pumps and data collection system 
shall be started.  ▼B

start procedure and end on conclusion of the cycle.  
1.2.12.5. Sample switching  
1.2.12.5.1. Gaseous emissions  
1.2.12.5.1.1. Sampling from the diluted exhaust and dilution air shall be 
switched from one pair of sample bags to subsequent bag pairs, 
if necessary, at the end of each phase of the applicable WLTC to 
be driven.  
1.2.12.5.2. Particulate  
1.2.12.5.2.1. The requirements of paragraph 1.2.10.1.1.1. of this Sub-Annex 
shall apply.  
1.2.12.6. Dynamometer distance shall be included in all relevant test sheets 
for each phase.  
1.2.13. Ending the test  
1.2.13.1. The engine shall be turned off immediately after the end of the 
last part of the test.

continuous diluted measurement shall be checked. The test shall 
be considered acceptable if the difference between the pre-test and 
post-test results is less than 2 per cent of the calibration gas value.  
1.2.14.2. Bag analysis  
1.2.14.2.1. Exhaust gases and dilution air contained in the bags shall be 
analysed as soon as possible. Exhaust gases shall, in any event, 
be analysed not later than 30 minutes after the end of the cycle 
phase.  
The gas reactivity time for compounds in the bag shall be taken 
into consideration.  
1.2.14.2.2. As soon as practical prior to analysis, the analyser range to be 
used for each compound shall be set to zero with the appropriate 
zero gas.  
1.2.14.2.3. The calibration curves of the analysers shall be set by means of 
calibration gases of nominal concentrations of 70 to 100 per cent 
of the range.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 590  
1.2.14.2.4. The zero settings of the analysers shall be subsequently rechecked: 
if any reading differs by more than 2 per cent of the range from 
that set in paragraph 1.2.14.2.2. of this Sub-Annex, the procedure 
shall be repeated for that analyser.  
1.2.14.2.5. The samples shall be subsequently analysed.  
1.2.14.2.6. After the analysis, zero and calibration points shall be rechecked 
using the same gases. The test shall be considered acceptable if 
the difference is less than 2 per cent of the calibration gas value.  
1.2.14.2.7. The flow rates and pressures of the various gases through 
analysers shall be the same as those used during calibration of 
the analysers.  
1.2.14.2.8. The content of each of the compounds measured shall be included 
in all relevant test sheets after stabilization of the measuring 
device.  
1.2.14.2.9. The mass and number of all emissions, where applicable, shall be 
calculated according to Sub-Annex 7.  
1.2.14.2.10. Calibrations and checks shall be performed either:  
(a) Before and after each bag pair analysis; or  
(b) Before and after the complete test.  
In case (b), calibrations and checks shall be performed on all 
analysers for all ranges used during the test.  
In both cases, (a) and (b), the same analyser range shall be used 
for the corresponding ambient air and exhaust bags.  
1.2.14.3. Particulate sample filter weighing  
1.2.14.3.1. The particulate sample filter shall be returned to the weighing 
chamber (or room) no later than 1 hour after completion of the 
test. It shall be conditioned in a petri dish, which is protected 
against dust contamination and allows air exchange, for at least 
1 hour, and weighed. The gross weight of the filter shall be 
included in all relevant test sheets.  
1.2.14.3.2. At least two unused reference filters shall be weighed within 8 
hours of, but preferably at the same time as, the sample filter 
weighings. Reference filters shall be of the same size and 
material as the sample filter.  
1.2.14.3.3. If the specific weight of any reference filter changes by more than 
± 5 μg between sample filter weighings, the sample filter and 
reference filters shall be reconditioned in the weighing chamber 
(or room) and reweighed.  
1.2.14.3.4. The comparison of reference filter weighings shall be made 
between the specific weights and the rolling arithmetic average 
of that reference filter's specific weights. The rolling arithmetic 
average shall be calculated from the specific weights collected 
in the period after the reference filters were placed in the 
weighing chamber (or room). The averaging period shall be at 
least one day but not more than 15 days.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 591  
1.2.14.3.5. Multiple reconditionings and reweighings of the sample and 
reference filters are permitted until a period of 80 hours has 
elapsed following the measurement of gases from the emissions 
test. If, prior to or at the 80 hour point, more than half the number 
of reference filters meet the ± 5 μg criterion, the sample filter 
weighing may be considered valid. If, at the 80 hour point, two 
reference filters are employed and one filter fails the ± 5 μg 
criterion, the sample filter weighing may be considered valid 
under the condition that the sum of the absolute differences 
between specific and rolling means from the two reference 
filters shall be less than or equal to 10 μg. 
1.2.14.3.6. In the case that less than half of the reference filters meet the ± 5 
μg criterion, the sample filter shall be discarded, and the emissions 
test repeated. All reference filters shall be discarded and replaced 
within 48 hours. In all other cases, reference filters shall be 
replaced at least every 30 days and in such a manner that no 
sample filter is weighed without comparison to a reference filter 
that has been present in the weighing chamber (or room) for at 
least one day.  
1.2.14.3.7. If the weighing chamber (or room) stability criteria outlined in 
paragraph 4.2.2.1. of Sub-Annex 5 are not met, but the 
reference filter weighings meet the above criteria, the vehicle 
manufacturer has the option of accepting the sample filter 
weights or voiding the tests, repairing the weighing chamber (or 
room) control system and re-running the test.  ▼B

Sub-Annex 6  
Appendix 1  
Emissions test procedure for all vehicles equipped with periodically 
regenerating systems  
1. General  
1.1. This Appendix defines the specific provisions regarding testing a 
vehicle equipped with periodically regenerating systems as defined in 
paragraph 3.8.1. of this Annex.  
Upon request of the manufacturer and with approval of the approval 
authority, a manufacturer may develop an alternative procedure to 
demonstrate its equivalency, including filter temperature, loading 
quantity and distance driven. This may be done on an engine bench 
or on a chassis dynamometer.  
Alternatively to carrying out the test procedures defined in this 
Appendix, a fixed K  i value of 1,05 may be used for CO  2 and fuel 
consumption.  
1.2. During cycles where regeneration occurs, emission standards need not 
apply. If a periodic regeneration occurs at least once per Type 1 test and 
has already occurred at least once during vehicle preparation, it does not 
require a special test procedure. In this case, this Appendix does not 
apply.  
1.3. The provisions of this Appendix shall apply for the purposes of PM 
measurements only and not PN measurements.  
1.4. At the request of the manufacturer, and with approval of the approval 
authority, the test procedure specific to periodically regenerating 
systems will not apply to a regenerative device if the manufacturer 
provides data demonstrating that, during cycles where regeneration 
occurs, emissions remain below the emissions limits for the relevant 
vehicle category.  
1.5. At the request of the manufacturer and with the agreement of the 
approval authority the Extra High phase may be excluded for deter ­
mining the regenerative factor K_i for Class 2 and Class 3 vehicles.  
2. Test Procedure  
The test vehicle shall be capable of inhibiting or permitting the regen ­
eration process provided that this operation has no effect on original 
engine calibrations. Prevention of regeneration is only permitted during 
loading of the regeneration system and during the preconditioning 
cycles. It is not permitted during the measurement of emissions 
during the regeneration phase. The emission test shall be carried out 
with the unchanged, original equipment manufacturer's (OEM) control 
unit. At the request of the manufacturer and with approval of the 
approval authority, an ‘engineering control unit’ which has no effect 
on original engine calibrations may be used during K  i determination.  
2.1. Exhaust emissions measurement between two WLTCs with regeneration 
events  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 593  
2.1.1. The arithmetic average emissions between regeneration events and 
during loading of the regenerative device shall be determined from 
the arithmetic mean of several approximately equidistant (if more 
than two) Type 1 tests. As an alternative, the manufacturer may 
provide data to show that the emissions remain constant (± 15 per 
cent) on WLTCs between regeneration events. In this case, the 
emissions measured during the Type 1 test may be used. In any other 
case, emissions measurements for at least two Type 1 cycles shall be 
completed: one immediately after regeneration (before new loading) and 
one as close as possible prior to a regeneration phase. All emissions 
measurements shall be carried out according to this Sub-Annex and all 
calculations shall be carried out according to paragraph 3. of this 
Appendix.  
2.1.2. The loading process and determination shall be made during the Type 1 
driving cycle on a chassis dynamometer or on an engine test bench 
using an equivalent test cycle. These cycles may be run continuously 
(i.e. without the need to switch the engine off between cycles). After 
any number of completed cycles, the vehicle may be removed from the 
chassis dynamometer and the test continued at a later time.  
2.1.3. The number of cycles D between two WLTCs where regeneration 
events occur, the number of cycles over which emission measurements 
are made n and mass emissions measurement M ′ sij for each compound i 
over each cycle j shall be included in all relevant test sheets.  
2.2. Measurement of emissions during regeneration events  
2.2.1. Preparation of the vehicle, if required, for the emissions test during a 
regeneration phase, may be completed using the preconditioning cycles 
in paragraph 1.2.6. of this Sub-Annex or equivalent engine test bench 
cycles, depending on the loading procedure chosen in paragraph 2.1.2. 
of this Sub-Annex.  
2.2.2. The test and vehicle conditions for the Type 1 test described in this 
Annex apply before the first valid emission test is carried out.  
2.2.3. Regeneration shall not occur during the preparation of the vehicle. This 
may be ensured by one of the following methods:  
2.2.3.1. A ‘dummy’ regenerating system or partial system may be fitted for the 
preconditioning cycles.  
2.2.3.2. Any other method agreed between the manufacturer and the approval 
authority.  
2.2.4. A cold start exhaust emissions test including a regeneration process 
shall be performed according to the applicable WLTC.  
2.2.5. If the regeneration process requires more than one WLTC, each WLTC 
shall be completed. Use of a single particulate sample filter for multiple 
cycles required to complete regeneration is permissible.  
2.2.5.1. If more than one WLTC is required, subsequent WLTC(s) shall be 
driven immediately, without switching the engine off, until complete 
regeneration has been achieved. In the case that the number of gaseous 
emission bags required for the multiple cycles would exceed the number 
of bags available, the time necessary to set up a new test shall be as 
short as possible. The engine shall not be switched off during this 
period.  ▼B

Test procedure for electric power supply system monitoring  
1. General  
In the case that NOVC-HEVs and OVC-HEVs are tested, Appendices 2 
and 3 of Sub-Annex 8 shall apply.  
This Appendix defines the specific provisions regarding the correction of 
test results for CO  2 mass emission as a function of the energy balance 
ΔE REESS  for all REESSs.  
The corrected values for CO  2 mass emission shall correspond to a zero 
energy balance ( ΔE REESS  = 0), and shall be calculated using a correction 
coefficient determined as defined below.  
2. Measurement equipment and instrumentation  
2.1. Current measurement  
REESS depletion shall be defined as negative current.  
2.1.1. The REESS current(s) shall be measured during the tests using a clamp- 
on or closed type current transducer. The current measurement system 
shall fulfil the requirements specified in Table A8/1. The current trans ­
ducer(s) shall be capable of handling the peak currents at engine starts 
and temperature conditions at the point of measurement.  
2.1.2. Current transducers shall be fitted to any of the REESS on one of the 
cables connected directly to the REESS and shall include the total REESS 
current.  
In case of shielded wires, appropriate methods shall be applied in 
accordance with the approval authority.  
In order to easily measure REESS current using external measuring 
equipment, manufacturers should preferably integrate appropriate, safe 
and accessible connection points in the vehicle. If this is not feasible, 
the manufacturer shall support the approval authority by providing the 
means to connect a current transducer to the REESS cables in the manner 
described above.  
2.1.3. The measured current shall be integrated over time at a minimum 
frequency of 20 Hz, yielding the measured value of Q, expressed in 
ampere-hours Ah. The measured current shall be integrated over time, 
yielding the measured value of Q, expressed in ampere-hours Ah. The 
integration may be done in the current measurement system.  
2.2. Vehicle on-board data  
2.2.1. Alternatively, the REESS current shall be determined using vehicle-based 
data. In order to use this measurement method, the following information 
shall be accessible from the test vehicle:  ▼B

(a) Integrated charging balance value since last ignition run in Ah;  
(b) Integrated on-board data charging balance value calculated at a 
minimum sample frequency of 5 Hz;  
(c) The charging balance value via an OBD connector as described in 
SAE J1962.  
2.2.2. The accuracy of the vehicle on-board REESS charging and discharging 
data shall be demonstrated by the manufacturer to the approval authority.  
The manufacturer may create a REESS monitoring vehicle family to 
prove that the vehicle on-board REESS charging and discharging data 
are correct. The accuracy of the data shall be demonstrated on a represen ­
tative vehicle.  
The following family criteria shall be valid:  
(a) Identical combustion processes (i.e. positive ignition, compres ­
sion→ignition, two-stroke, four-stroke);  
(b) Identical charge and/or recuperation strategy (software REESS data 
module);  
(c) On-board data availability;  
(d) Identical charging balance measured by REESS data module;  
(e) Identical on-board charging balance simulation.  
3. REESS energy change-based correction procedure  
3.1. Measurement of the REESS current shall start at the same time as the test 
starts and shall end immediately after the vehicle has driven the complete 
driving cycle.  
3.2. The electricity balance Q measured in the electric power supply system, 
shall be used as a measure of the difference in the REESS energy content 
at the end of the cycle compared to the beginning of the cycle. The 
electricity balance shall be determined for the total WLTC for the 
applicable vehicle class.  
3.3. Separate values of Q  phase shall be logged over the cycle phases required 
to be driven for the applicable vehicle class.  
3.4. Correction of CO  2 mass emission over the whole cycle as a function of 
the correction criterion c.  
3.4.1. Calculation of the correction criterion c  
The correction criterion c is the ratio between the absolute value of the

test cycle, km;  
10 conversion factor to Wh.  
3.4.2. The correction shall be applied if ΔE REESS  is negative (corresponding to 
REESS discharging) and the correction criterion c calculated according to 
paragraph 3.4.1. of this Sub-Annex is greater than the applicable tolerance 
according to Table A6.App2/2.  
3.4.3. The correction shall be omitted and uncorrected values shall be used if 
the correction criterion c calculated according to paragraph 3.4.1. of this 
Sub-Annex is less than the applicable tolerance according to Table 
A6.App2/2.  
3.4.4. The correction may be omitted and uncorrected values may be used if:  
(a) ΔE REESS  is positive (corresponding to REESS charging) and the 
correction criterion c calculated according to paragraph 3.4.1. of 
this Sub-Annex is greater than the applicable tolerance according to 
Table A6.App2/2;  
(b) the manufacturer can prove to the approval authority by measurement 
that there is no relation between ΔE REESS  and CO  2 mass emission and 
ΔE REESS  and fuel consumption respectively.

η alternator ¼ 0,67 for electric power supply system REESS alternators  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 602

and all vehicles H of the interpolation families within the ATCT 
Family, the end temperature of the engine coolant shall be measured 
after driving the respective Type 1 test at 23 °C and after soaking at 
23 °C for the duration of t  soak_ATCT  , with a tolerance of an additional 15 
minutes.  
3.9.1.1. In the case that t  soak_ATCT  was extended in the respective ATCT test, 
the same soaking time shall be used, with a tolerance of an additional 
15 minutes.  
3.9.2. The cool down procedure shall be undertaken as soon as possible after

measured soaking time is the time between the measurement of the end 
temperature and the end of the Type 1 test at 23 °C, and shall be 
included in all relevant test sheets.  
3.9.3. The average soak area temperature of the last 3 hours of the soak 
process has to be subtracted from the measured end temperature of 
the engine coolant at the end of the soaking time specified in 
paragraph 3.9.1. This is referred to as Δ T_ATCT  . 
3.9.4. Unless the resulting Δ T_ATCT  is within the range of – 2 °C to + 4 °C 
from the reference vehicle, this Interpolation Family shall not be 
considered to be a member of the same ATCT Family.  
3.9.5. For all vehicles within an ATCT Family the coolant shall be measured 
at the same location in the cooling system. That location shall be as 
close as possible to the engine so that the coolant temperature is as 
representative as possible to the engine temperature.  
3.9.6. The measurement of the temperature of the soak areas shall be as 
specified in paragraph 3.2.2.2. of this Sub-Annex.  ▼B

Rf CH4 is the FID response factor to methane as defined in 
paragraph 5.4.3.2. of Sub-Annex 5.  
3.2.1.1.3.2. For methane measurement using an NMC-FID, the calculation of

Shortened Type 1 test procedure speed trace
  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 645  
The dynamic segments DS  1 and DS  2 are used to determine the 
energy consumption for the applicable WLTP test cycle.  
The constant speed segments CSS  M and CSS  E are intended to 
reduce test duration by depleting the REESS more rapidly than 
the consecutive cycle Type 1 test procedure.  
3.4.4.2.1.1. Dynamic segments  
Each dynamic segment DS  1 and DS  2 consists of an applicable 
WLTP test cycle according to paragraph 1.4.2.1. followed by an 
applicable WLTP city test cycle according to paragraph 1.4.2.2.  
3.4.4.2.1.2. Constant speed segment  
The constant speeds during segments CSS  M and CSS  E shall be 
identical. If the interpolation approach is applied, the same 
constant speed shall be applied within the interpolation family.  
(a) Speed specification  
The minimum speed of the constant speed segments shall be 
100 km/h. At the request of manufacturer and with approval of 
the approval authority, a higher constant speed in the constant 
speed segments may be selected.  
The acceleration to the constant speed level shall be smooth and 
accomplished within 1 minute after completion of the dynamic 
segments and, in the case of a break according to Table A8/4, 
after initiating the powertrain start procedure.  
If the maximum speed of the vehicle is lower than the required 
minimum speed for the constant speed segments according to 
the speed specification of this paragraph, the required speed in 
the constant speed segments shall be equal to the maximum 
speed of the vehicle.  
(b) Distance determination of CSS  E and CSS  M 
The length of the constant speed segment CSS  E shall be 
determined based on the percentage of the usable REESS 
energy UBE  STP according to paragraph 4.4.2.1. of this Sub- 
Annex. The remaining energy in the traction REESS after 
dynamic speed segment DS  2 shall be equal to or less than 10 
per cent of UBE  STP . The manufacturer shall provide evidence to 
the approval authority after the test that this requirement is 
fulfilled.  
The length of the constant speed segment CSS  M may be 
calculated using the following equation:  
d CSSM ¼ PER  est Ä d DS1 Ä d DS2 Ä d CSSE 
where:  
PER  est is the estimated pure electric range of the considered 
PEV, km;  
d DS1 is the length of dynamic speed segment 1, km;  
d DS2 is the length of dynamic speed segment 2, km;  
d CSSE is the length of constant speed segment CSS  E , km.  ▼B

This Appendix describes the procedure to correct the charge-sustaining Type 1 
test CO  2 mass emission for NOVC-HEVs and OVC-HEVs, and the fuel 
consumption for NOVC-FCHVs as a function of the electric energy change of 
all REESSs.

2.1. The CO  2 mass emission correction coefficient K  CO2 , the fuel 
consumption correction coefficients K  fuel,FCHV  , as well as, if 
required by the manufacturer, the phase-specific correction coef ­
ficients K  CO2,p  and K  fuel,FCHV,p  shall be developed based on the 
applicable charge-sustaining Type 1 test cycles.  
In the case that vehicle H was tested for the development of the

family.  
2.2. The correction coefficients shall be determined from a set of charge- 
sustaining Type 1 tests according to paragraph 3. of this Appendix. 
The number of tests performed by the manufacturer shall be equal to 
or greater than five.  
The manufacturer may request to set the state of charge of the REESS 
prior to the test according to the manufacturer’s recommendation and 
as described in paragraph 3. of this Appendix. This practice shall only 
be used for the purpose of achieving a charge-sustaining Type 1 test 
with opposite sign of the ΔE REESS,CS  and with approval of the 
approval authority.  
The set of measurements shall fulfil the following criteria:

(b) The difference in M  CO2,CS  between the test with the highest 
negative electric energy change and the test with the highest 
positive electric energy change shall be greater than or equal to 
5 g/km. This criterion shall not be applied for the determination of 
K fuel,FCHV  . 
In the case of the determination of K  CO2 , the required number of 
tests may be reduced to three tests if all of the following criteria 
are fulfilled in addition to (a) and (b):  
(c) the difference in M  CO2,CS  between any two adjacent measure ­
ments, related to the electric energy change during the test, 
shall be less than or equal to 10 g/km.  
(d) in addition to (b), the test with the highest negative electric energy 
change and the test with the highest positive electric energy 
change shall not be within the region that is defined by:

negative electric energy change and the mid-point, and the 
difference in M  CO2,CS  between mid-point and the test with the 
highest positive electric energy change shall be similar and 
preferably be within the range defined by (d).  
The correction coefficients determined by the manufacturer shall 
be reviewed and approved by the approval authority prior to its 
application.  
If the set of at least five tests does not fulfil criterion (a) or 
criterion (b) or both, the manufacturer shall provide evidence to 
the approval authority as to why the vehicle is not capable of 
meeting either or both criteria. If the approval authority is not 
satisfied with the evidence, it may require additional tests to be 
performed. If the criteria after additional tests are still not fulfilled, 
the approval authority will determine a conservative correction 
coefficient, based on the measurements.

Preconditioning, soaking and REESS charging conditions of PEVs and 
OVC-HEVs  
1. This Appendix describes the test procedure for REESS and combustion 
engine preconditioning in preparation for:  
(a) Electric range, charge-depleting and charge-sustaining measurements 
when testing OVC-HEVs; and  
(b) Electric range measurements as well as electric energy consumption 
measurements when testing PEVs.  
2. OVC-HEV preconditioning and soaking  
2.1. Preconditioning and soaking when the test procedure starts with a 
charge-sustaining test  
2.1.1. For preconditioning the combustion engine, the vehicle shall be driven 
over at least one applicable WLTP test cycle. During each driven 
preconditioning cycle, the charging balance of the REESS shall be 
determined. The preconditioning shall be stopped at the end of the 
applicable WLTP test cycle during which the break-off criterion is 
fulfilled according to paragraph 3.2.4.5. of this Sub-Annex.  
2.1.2. As an alternative to paragraph 2.1.1. of this Appendix, at the request of 
the manufacturer and upon approval of the approval authority, the state 
of charge of the REESS for the charge-sustaining Type 1 test may be 
set according to the manufacturer’s recommendation in order to achieve 
a test under charge-sustaining operating condition.  
In such a case, a preconditioning procedure, such as that applicable to 
conventional vehicles as described in paragraph 1.2.6. of Sub-Annex 6, 
shall be applied.  
2.1.3. Soaking of the vehicle shall be performed according to paragraph 1.2.7. 
of Sub-Annex 6.  
2.2. Preconditioning and soaking when the test procedure starts with a 
charge-depleting test  
2.2.1. OVC-HEVs shall be driven over at least one applicable WLTP test 
cycle. During each driven preconditioning cycle, the charging balance 
of the REESS shall be determined. The preconditioning shall be stopped 
at the end of the applicable WLTP test cycle during which the break-off 
criterion is fulfilled according to paragraph 3.2.4.5. of this Sub-Annex.  
2.2.2. Soaking of the vehicle shall be performed according to paragraph 1.2.7. 
of Sub-Annex 6. Forced cooling down shall not be applied to vehicles 
preconditioned for the Type 1 test. During soak, the REESS shall be 
charged using the normal charging procedure as defined in paragraph 
2.2.3. of this Appendix.  
2.2.3. Application of a normal charge  
2.2.3.1. The REESS shall be charged at an ambient temperature as specified in 
paragraph 1.2.2.2.2. of Sub-Annex 6 either with:  
(a) The on-board charger if fitted; or  
(b) An external charger recommended by the manufacturer using the 
charging pattern prescribed for normal charging.  ▼B
 02017R1151 — EN — 27.07.2017 — 001.003 — 702  
The procedures in this paragraph exclude all types of special charges 
that could be automatically or manually initiated, e.g. equalization 
charges or servicing charges. The manufacturer shall declare that, 
during the test, a special charge procedure has not occurred.  
2.2.3.2. End-of-charge criterion  
The end-of-charge criterion is reached when the on-board or external 
instruments indicate that the REESS is fully charged.  
3. PEV preconditioning  
3.1. Initial charging of the REESS  
Initial charging of the REESS consists of discharging the REESS and 
applying a normal charge.  
3.1.1. Discharging the REESS  
The discharge procedure shall be performed according to the manufac ­
turer’s recommendation. The manufacturer shall guarantee that the 
REESS is as fully depleted as is possible by the discharge procedure.  
3.1.2. Application of a normal charge  
The REESS shall be charged according to paragraph 2.2.3.1. of this 
Appendix.  ▼B

Appendix 5  
Utility factors (UF) for OVC-HEVs  
1. Utility Factors (UFs) are ratios based on driving statistics and the ranges 
achieved in charge-depleting mode and charge-sustaining modes for 
OVC-HEVs and are used for weighting emissions, CO  2 emissions and fuel 
consumptions.  
The database used to calculate the Utility Factors in paragraph 2. was 
predominantly based on the use characteristics (e.g. utilization, daily driven 
distance, shares of different vehicle classes) of conventional vehicles. It will 
be necessary to re-evaluate UF and charging frequencies by a customer study 
once a significant number of OVC-HEV vehicles are in use in the European 
market.  
2. For the calculation of each phase specific utility factor (UF), the following 
equation shall be applied:  
UF  i ðd i Þ ¼ 1 Ä exp 8

j¼1 C j Ü 8 
: d i 
d n 9

Where:  
UF  i Utility factor for phase i.  
d i Distance driven to the end of phase i in km.  
C j j th coefficient (see Table A8.App5/1).  
d n Normalized distance (see Table A8.App5/1).

A8.App5/1).

l¼1 UF  l Sum of calculated utility factors up to phase (i-1).  
The curve that is based on the following parameters in Table A8.App5/1 is

(as can be seen in Figure A8/App5/1).
