2. PEMS Test campaigns – Objectives
Primarily to address:
The improvement or fine-tuning of the currently available PEMS testing and data evaluation procedures
The sharing of know-how and best practices with PEMS testing and data evaluation
Additionally, to contribute to:
The definition of “acceptable testing conditions”, in line with the boundary conditions
A better understanding of realistic “RDE emissions targets”

3. References & Tools RDE-LDV Work Plan – Version 7 (15/10/2012

4. PEMS Test campaigns – Organisation
JRC and/or participating entities will provide test vehicles
Phase 1: 4 vehicles [Until mid-2013]
Phase 2: Additional vehicles [Until end 2013]
Possibly representative for EURO 6 engine, after- treatment and powertrain technologies
The test vehicles will be tested on laboratory cycles (NEDC, WLTP, RDE) by JRC and/or participants
JRC will provide the PEMS equipment for both PEMS tests at JRC and other test sites (2 Units available for the first phase whole exercise)

5. PEMS Test protocol – Minimum requirements
In general, the testing protocol in Annex I shall apply
No vehicle conditioning is needed (i.e., starting after outside or garage parking) but the vehicle parking/weather conditions shall be recorded;
Emissions sampling shall start before engine on;
Measurements shall cover CO2 and the regulated gaseous criteria pollutants.
An external power source (batteries recommended) shall be used to power-up the PEMS equipment;
The total weight of the installed PEMS equipment shall be measured and recorded;

6. PEMS Test protocol – Minimum requirements
The measurement performance of the PEMS equipment shall be in accordance with existing regulatory requirements;
The total weight of the installed PEMS equipment shall be measured, recorded and shall not exceed the vehicle allowed payload and x kg [to be defined];

7. PEMS Test protocol – Minimum requirements
Each emissions test shall have a minimum duration of 1 hour, engaging on a variety of conditions either during the same test or during different tests (Urban, Rural, Motorway, Uphill or downhill);
PEMS emissions tests shall be conducted during normal working days (Monday to Friday) and during daytime.

8. Optional elements
PEMS test protocol: Road grade, head wind and THC measurements
Vehicles tested with 2 PEMS systems (simultaneously or not, on the same routes or not)

9. Complementary laboratory tests
Vehicles shall be tested on NEDC, WLTP (cold start)
Vehicles shall be tested on Random Cycles whose phases duration shall be between 8 and 12 minutes each (total cycle duration between 24 and 36 minutes)
Bag measurements for each phase
Modal measurements required
Comparison laboratory PEMS equipment to be conducted on some cycles
PM and PN for diesek vehicles
