Test report (xx/2015)
Certificate (xx/2015)
Families
Extension rules

Reminder
The purpose of this group is to determine how to approve a vehicle and make recommendations to the AdminWG.
It will then be the AdminWG that agrees and prepares the requirements/text to be included in the new EU WLTP regulation.
Remarks
This is a working document for the expert TF: comments, proposal and agreement are blue
Each reference to a regulation is written in ‘Times new roman’
When the Vehicle Low (VL) is mentioned: when existing (interpolation approach)
Actions are highligthed in red
21-22/05/2015
TA process with WLTP 2

3. Test Current agreement / Text Proposal/agreement/comment
Choice of the tested vehicles
The choice of VL and VH is an agreement between TS/TAA and OEM
The information about the tested vehicle is provided in the information document
Checking of their parameter (by testing, calculation)
'virtual' vehicle (not produced) agreement
Same vehicle tested (H and L)
The only difference between VL and VH is the roadload
Number of test
CO2/FC rules (dp1, dp2)
CO2/FC rules are at least on combined results.
Are they applicable for each phase?
Action EC to answer – see also conclusion from EU WLTP meeting 11/5/15.
Pollutant rules
Interaction?
JRC proposal (A. Marotta) for GRPE (June) ongoing
CO2/FC: results on test report (692/2008) and test result (ann VIII 2007/46)
Pollutants PASS/FAIL criteria (character) + results in the test report (692/2008)
Question: KBA/German (or other MS) position?
21-22/05/2015
TA process with WLTP

4. Information document 1/4
Current agreement
/ Text (xx/2015 annex I appendix 3)
Proposal/agreement/comment
Declaration of:
14°C family
Roadload family
RDE family?
How-where to identify the families?
- Roadload + ATCT: test results (e.g. coastdown results in the document)
- RDE: ?
What about TA issued by different TAAs (e.g. for roadload and ATCT)?
Responsibility lies with the TAA that issues the type approval certificate (with information from different TS)
GENERAL CONSTRUCTION CHARACTERISTICS OF THE VEHICLE
The only difference between the physical VL and VH is the roadload
(and transmission in tolerance of 0-8%)

5. Information document 2/4
Current agreement
/ Text (xx/2015 annex I appendix 3)
Proposal/agreement/comment
2. MASSES AND DIMENSIONS (in kg and mm)
(reminder: TM of Vind : actual mass of Vind + 25 kg + mass representative of payload)
MRO, maximum and reference masses for VL and VH
TM of VL and VH
 Modification of appendix of information document (“test conditions”)
(ann I&III of 2007/46) 2.6.2: mass of the optional equipment
To be changed in “maximum mass of…”
Need to check alignment of 2007/46 and 692/2008 for Mass in Running Order
3.5. CO2 emissions/fuel consumption (manufacturer’s declared value)
for VL and VH:
CO2-FC declaration in WLTP on each phase + combined final values (after corrections)
During transient period in NEDC on combined and phases (for metamodel/double testing)
Other ‘short-lived’ regulation on correlation could be introduced for transitional period
interpolation family needed (physical WLTP results) for MM

for all tyre options indicate, size designation, load-capacity index, speed category symbol, rolling resistance to ISO (where applicable)
for tyres of category Z intended to be fitted on vehicles whose maximum speed exceeds 300 km/h equivalent information shall be provided; for wheels indicate rim size(s) and off-set(s)
(quite the same in ann I & ann III of the 2007/46)
 Action To be clarified/harmonised by EC (KS)
VH and VL RR is already included in the “test conditions” appendix
 6.6. Tyres dimensions
for tyres of category Z intended to be fitted on vehicles whose maximum speed exceeds 300 km/h equivalent information shall be provided;  still relevant? R117? Not included in the 2007/46 for wheels indicate rim size(s) and off-set(s)
Aerodrag of VH and VL
See appendix “test conditions”
and Spark plug + ignition coil
(ann I 2007/46)  to be added in the information document (annI app3 of xx/2015)
Erased from “test conditions” appendix
See attached document
4.7. Maximum vehicle design speed (in 2007/46 not in xx/2015)
 to be added for harmonisation

TA process with WLTP

7. Information document 4/4
Gear shift
Idling speed  same as (annex 1 appendix 3 xx/2015 and annexes I & III 2007/46)
Additional safety margin (2 values)
nmin drive (if the OEM declares higher than GTR calculated values)
Maximum power curve (Pwot(nnorm))
Need to be added in the information document  Action AdminWG
EC proposal to add result of the tool for gearshifting (VH & VL)
It represents around 150 points.
Action: H. Steven will have a proposal to have one number (for instance averaging gear shift)
 Unic number specific to one vehicle (one for VH, one for VL)
 Aim: to have a checksum -> easy to control / easy to calculate
 EC agrees with this idea (need to see the proposal)
 Action TF to propose where it could be register:
in the proposal « information on tests condition »?
or test report (xx/2015)?
Reminder about Gearshfting:
Need a full description of the calculation in xx/2015
Add an Excel sheet for calculation? (EU or UNECE websites): Action
Remark:
Gear shifting depends on specific characteristics of the tested vehicles (effective radius)

TA process with WLTP

9. Test report (xx/2015) 2/3 Current agreement / Text
Proposal/agreement/comment
Electrified vehicles:
Transitional period: choice of vehicle to test (no interpolation approach)
Decide how to deal with hybrid vehicles
Reminder of electrified vehicles results:
WLTP:
- CD (OVC+PEV): Criteria Emissions, FC, CO2, AER, EAER, RCDC, RCDA, EAC
- CS (OVC+NOVC): Criteria Emissions, FC, CO2
WLTP city
CD (OVC+PEV): AERcity, EACcity
ACEA proposal: still ongoing
Action ACEA to provide a proposal
Need a template of minimal information ?
A template needs to be defined (minimum information)
Action TF to write a proposal
From certificate template (first)
ATCT
Action LB + A. Eder to check if the text is clear
3.8.3 FCF documentation requirement (sub annex 6a)  to be clarified
How and when to apply?

TA process with WLTP

10. Test report (xx/2015) 3/3 Current agreement / Text
Proposal/agreement/comment
Other tests during transitional period:
OBD
Durability Ki
For Ki:
Information document
(annex I appendix 3 xx/2015 // 2007/46 annexes I and III)
To be modified to specify which type 1 (NEDC or WLTP)
For those tests : if NEDC  NEDC roadload used
OBD: ACEA + EC discussions ongoing
Action EC+ACEA
Ki (phase 1b) included in xx/2015? If NEDC Ki and WLTP Ki could be used it has to be declared somewhere
Ki and Durability : accepted to keep NEDC values for a transitional period
Action ACEA to provide a proposal (especially on Ki)
Discussion:
Ki NEDC used until monitoring ‘base year’ because of Ki needed for correlation
or need to be correlated (from WLTP)
Action TF to modify addendum of TA certificate // information doc (xx/2015 and 2007/46)
 By using characters ? (A, B, …, ZX??)
21-22/05/2015
TA process with WLTP

11. Reporting: work on test report AdminWG-38
The document has been separated into 3 documents
Test sheet
Test report
Recorded but no need to be kept
« Test sheet » means kept by the OEM
 to be defined
Content
How long will it be kept?
Test Report – currently each TAA uses a different format. Agreed that having some form of harmonisation would be beneficial.

Does it still exist?
See details :
Version definition (2007/46 annex II part B)
Proposal:
(k) for transition period, NEDC based EI  to keep EI in the version definition ?
(h), (i) and (j)  “combined or weighted, combined xxx on NEDC” (where xxx is either CO2, or energy or fuel consumption)
692/2008 Article 2
Proposal : remove (a)?
NB: editorial note footnote (2) refers to the OJ  if (a) is deleted the footnote will need to be moved to the next reference to Reg.83?

What becomes of the DAM?
Combined approach for N-category vehicles
 Classes versus VH-VL definition
EC position: no problem to have different emissions limits (from different classes) and a interpolation between VL and VH for CO2/FC
Other categories of vehicles M2, N1 cl1, 2, 3 …
Dates, masses…
Action TF to work on it (character…?)
Smoke opacity
Still relevant in the EU-WLTP? (no more reference to R24 in 582/2011 (Heavy Duty)
xx/2015 may be needed for periodic inspection (regulation)
