VOC-Emission

Automotive suppliers need to validate the compliance of their components to certain OEM specifications for emission behavior prior to their use in the vehicle interior.

All plastic materials (thermoplastics, elastomers, thermosets and composites) can release volatile organic compounds (VOCs) into the ambient air. Depending on their concentration, these VOCs have an influence on the odor perception, well-being or health of people inside the vehicle.

As a result the automotive industry has issued regulations for certain substances and substance classes in the field of vehicle indoor air quality (VIAQ).

The emission behavior is typically analyzed by the following test methods:

  • VOC determination
  • Odor testing
  • Fogging testing

 

Below is a selection of test procedures, which UL offers.
