Does a vehicle smell unpleasant or does the customer get a headache after ten minutes? Are all government requirements regarding vehicle indoor air quality (VIAQ) fulfilled? In order to answer such questions, vehicles can be examined in a special test chamber.
A wide range of scenarios in parking and driving mode can be simulated under clearly-defined boundary conditions. Different thermal loads typically encountered by stationary vehicles (e.g. solar radiation when parked) can also be simulated. In addition, the area around the vehicle can be specifically exposed to contaminants such as pollen, VOCs, nitrogen oxides, ozone or fine dust. This enables the efficiency of air filters for the vehicle interior, for example, to be determined. Air samples can be taken from the vehicle interior as required for online analysis, or for comprehensive substance-specific analysis in the laboratory. The air inside the vehicle can also be evaluated for odors at any time. If desired, the source(s) of any unpleasant odors can be located.
Besides these special tests, we also conduct tests according to common standards, such as DIN ISO 12219-1, or according to the specifications of Asian manufacturing companies (GB/T 27630-2011, JAMA).
