Exterior Exposure Testing

 

ASTM D 1006-01

 

Berea, OH exposure site. Open backed metal racks on asphalt slab.  Open backed panels will be used unless otherwise specified.   Panels typically exposed at 45° South.

 

Additional asphalt area available for horizontal panel exposure (deck stains).  If necessary horizontal coatings can be exposed on pallets.  Panels will be evaluated typically at 6 months, 1 year, and 2 years unless otherwise specified.  A report will detail substrate type and a client can contact CRGI for any further details on the substrate used.  CRGI washes panels using dish soap and water. 

 

CRGI subcontracts panels to Q-Panel for exposure (Homestead ,Florida, and Buckeye, Arizona) if needed.

 

Berea weather information yearly averages is presented below.  Humidity is not available. This information is directly from the NOAA website www.noaa.gov .  It is from the weather station at Cleveland Hopkins airport which is about five miles away from Coatings Research Group Exposure Site.
