Studies are reported that will determine the effects of weather factors such as solar radiation, temperature, moisture, pollutants, hail and wind upon both traditional and innovative building materials. Other factors such as imposed stresses, growth of microorganisms, chemical and physical compatibility between adjoining materials, and the manner in which the materials is actually used may also be taken into consideration. This research on materials durability involves 2 types of tests: natural weathering tests which include the exposure of materials under in-service conditions; and accelerated weathering testing which is a laboratory simulation on an intensified scale of natural weathering factors. The tests which are conducted at the National Bureau of Standards' Exposure Stations, may be designed to investigate the effects of a single factor or a group of factors.
