1. WLTP Phase 2 Presentation and discussion of the Term of Reference for the Durability Task Force
Paris, April 2016
14th WLTP IWG meeting
DG GROW.C4

Set-up of the DTF
Wrap-up and conclusion

3. Background
The WLTP IWG has received the mandate to develop durability requirements not only for conventional and electrified vehicles as regards to pollutant emissions, but also for the assessment of the REESS deterioration with mileage and time. WE propose that the Durability Task Force (DTF) take charge of the pollutant emissions part, while the EV subgroup lead the REESS deterioration aspects.

4. Objective of the Durability TF (DTF)
To define a procedure for assessing the evolution of pollutant emissions during the lifetime of the vehicle
Such procedure should cover all existing and future engine/vehicle technologies having an impact on emissions

5. Mandate of the DTF
be open to all experts, stakeholders and CP representatives that have an interest in WLTP;
be chaired by the European Commission;
develop a procedure to demonstrate the durability of pollutant control systems for the WLTP GTR;
act as a platform for the exchange of information and contributions of stakeholders, to be discussed and agreed during the development process;
report to the WLTP-IWG on the progress;
deliver technical advice and a GTR text proposal;
focus only on the technical issues regarding the procedure to be developed

6. ToR for the DTF Develop proposals along the following two lines:
Whole vehicle durability test;
Bench ageing durability test (normal and accelerated ageing).
In both cases:
Start with an analysis of the existing normative and literature on the method;
Prepare a comparative analysis amongst the different regional procedures;
Propose a way forward for the development of a harmonized procedure, including considerations on whether there is need for experimental activities and to what extent;
Develop the harmonized method;
Validate the method.
