Vehicle Interior Air Quality Testing


Hundreds of volatile organic compounds (VOCs), which off-gas from the materials and finishes used in car interiors, can be present in the air inside a new vehicle. VOCs can cause odor complaints and have been linked to numerous health concerns. As the demand for healthier products increases, vehicle manufacturers that tell a compelling sustainability story can capitalize on a significant opportunity to grow market share.
UL helps manufacturers capture value for their sustainability efforts, mitigate risks and comply with increasingly complex regulations.


UL helps manufacturers manage their supply chains to minimize VOC emissions from interior components with chemical emissions testing and advisory services. Chemical emissions testing uses advanced technology to detect and measure VOC emissions from materials and components. Our experts can help manufacturers select the best materials early in the design process, confirm performance of complete assemblies prior to mass production, and monitor the quality of raw materials throughout production of the vehicle.


Our global network of laboratories uses advanced technology to detect and measure VOC emissions from materials and components, and has capabilities for all major ISO, VDA, and manufacturer-specific test methods.

Through testing and advisory services, UL can help manufacturers manage their supply chain to help minimize VOC emissions from interior components.

UL provides trusted third-party scientific data to help manufacturers comply with complex regulations and expand into other markets.

Our advisory services can help vehicle component manufacturers make sustainable choices and avoid costly design changes and impacts to final vehicles that can delay product release.
