Automotive Interiors

Automotive interiors are comprised of a variety of materials and produced by several companies. To achieve a uniform appearance, automotive companies have tight quality control (QC) tolerances. Color tolerances are typically ­±0.5 for ΔL*, Δa*, Δb* and gloss tolerances are typically ±0.3 to 0.5 gloss units (GU).

Weathering is a routine performance test to determine durability of paint and plastics under extreme weather conditions. The most popular areas for weathering studies are located in AZ and South FL. Samples can also be placed into chambers that can simulate changes in temperature, humidity and UV levels. More…
