Measurements of exhaust emission via various methods (from sample bags, continuous measurments) over various drive cycles (NEDC, WLTC, FTP-75, HFET, US06, SC03, JC08, RDE or custom) in a climatic chamber with the following parameters:
- temperature control ranging from -35°C to +60°C, with an accuracy of ±1,2°C during emission testing,
- absolute humidity control during emission test ranging from 5,5 to 15,0 grams of water per 1 kg of dry air in the temperature range from +20°C to +35°C,
- humidity variation ≤ 5%.
The purpose of such tests is evaluation of the influence of different environmental conditions on the level of exhaust emissions.
