Synthetic and natural materials are used extensively by the motor vehicle industry to provide customers appealing and safe vehicle interiors. The materials used in all aspects of vehicles interior, range from cloth and leather seats to the plastics used in the dashboards. The manufacturing process used for these materials typically include volatile (VOC) and semi volatile organic compound (SVOC) which are released into the interior of vehicles.

These compounds give the vehicles that new smell but can also lead to fog on the interior glass surfaces of the car and health issues with the occupants. Vehicle manufactures and government regulatory agencies are investigating limits relating to the VOC and SVOC and their allowable concentrations in the interior of vehicles. The Japanese Automotive Manufactures Association (JAMA) and the voluntary program for the European Automotive Industry, VDA, whose limits are defined by TÜVRheinland are two of these agencies.
