Vehicle Indoor Air Quality Testing and Certification

Increase buyer satisfaction and avoid complaints with product emissions testing.

Inside of car


Since the early 2000s, researchhas demonstrated that vehicle indoor air contains volatile organic compounds (VOCs) emitted from interior components, such as plastics, fabrics and adhesives. In reality, that “new car smell” is chemicals emitting from interior components and it can cause health effects such as headaches, sore throat, nausea and drowsiness. And while emissions can taper off after the first several weeks after a product is manufactured, cars pose a challenge because interiors can heat up during warm weather and chemicals can continue emitting long after a vehicle is no longer considered new. It is critical to gain an understanding of the potential impact of VOC emissions during the research and development phase. Our chemical emissions testing utilizes advanced technology to detect and measure emissions emanating from products and components and determine their impacts on human health.


We can help you understand the chemical emissions potential of their vehicle interiors to:

  • Determine if chemical emissions from interiors pose a health risk for buyers
  • Avoid buyer complaints due to odor
  • Meet a variety of international requirements for vehicle indoor air quality including those in Japan, Korea and China

We can test to a variety of test global test methods. UL Solutions testing follows International Organization for Standardization (ISO) 12219 framework with the flexibility to meet regional and specific original equipment manufacturers (OEM) requirements
