Atlas Weathering Services Group, www.atlaswsg.com, is a global network of material testing and evaluation laboratories. Atlas has been testing for over 80 years and provides a wide range of climatic and environmental conditions ideal for material durability testing. The scientific staff at Rust Bullet chose Atlas Weathering Services Group as one of the real-time testing facilities because of its extensive experience and long established favorable reputation. Ten test panels were installed on Atlas outdoor testing racks at the Arizona facility on July 25, 2001. These test panels were identical to the panels used for the accelerated weathering tests that were performed at National Testing Standards, Inc.
