Vehicle Interior Air Quality – Quality You Can Breathe
The air we breathe in our vehicles has a direct impact on our well-being. Inside modern vehicles, volatile organic compounds (VOCs) released from materials and components can significantly impair the air quality and cause unpleasant odors.
To keep these emissions to a minimum, vehicle manufacturers (OEMs) define specific quality requirements for all components used in the vehicle – in particular for VOCs and odor emissions. Compliance with these requirements is verified using various high-precision laboratory test methods that vary depending on the type and properties of the materials.
Targeted test methods to ensure healthy interior air quality
The OEM-specific test procedures focus on the identification and quantification of chemical substances that are released from vehicle interior materials and components under defined conditions. These analyses are supplemented by sensory inspections that detect unpleasant odors in advance, thus ensuring an air quality that lasts.
In addition to general VOCs, the main focus is on formaldehyde, as this substance is subject to particularly low emission limits:
- OEM-specific requirements to minimize formaldehyde emissions
- Future REACH limit value: 0.062 mg/m³ in vehicle interiors
These specifications are intended to protect vehicle occupants and impose high standards on the materials used. We will draw on our comprehensive expertise to help you meet these requirements. In our DIN EN ISO 17025 accredited TÜV Rheinland Group emissions laboratory, we carry out all standard test methods in accordance with OEM specifications – precisely, reliably and in compliance with the standards.
