Several vehicle-level test procedures exist for measuring and analyzing volatile organic compound (VOC) emissions from new vehicle interiors. In this paper, four vehicle-level procedures were examined to determine the effect of interior air temperature (driver's side breath position), ventilation, vehicle age, and solar load (intensity and source) on the total VOC concentration. A new vehicle (11 days old) was tested over five weeks at interior air temperatures of ambient, 40°C, and 50°C with the ventilation on and off. Three sources of solar load were examined with loads between 600 and 1,100 W/m₂. The three sources of solar load were 5-Zones of halogen lights, an SC03 test site with metal halide lights, and the sun. Total VOCs were measured (μg/m₃) as well as individual hydrocarbons including formaldehyde. Six temperature points in and around the vehicle were monitored over the course of each test.
