Acid Rain Resistance Tests
Environmental Testing Equipment The ability to predict actual field performance of a product through accelerated laboratory conditions is necessary to assure long term performance and satisfied customers. The effects of prolonged exposure to heavy industrial air pollution are simulated in a special sulfur dioxide (Kesternich) cabinet (ASTM G 87). This test accelerates the effect of acid rain or other acidic environments in order to predict the long term performance of a material. All pigments used to formulate coatings for paneling are acid resistant, meaning they won’t change colors in an acid rain environment.
The Weather-Ometer is used to simulate exterior exposure, alternating periods of hot sunshine and periods of cool, damp darkness (ASTM D 3361 and G 23). This test accelerates the chalking and fading of paints in order to predict the long term performance of the finish. The Test Lab is also equipped to test materials for other atmospheric conditions including the corrosive effect of salt-laden air (ASTM B 117), reaction to prolonged high humidity (ASTM D 2247), the effect of ultraviolet light (ASTM D 795 and D 1501) on paints, plastics and rubbers, corrosion of metals and paints and the performance of materials after prolonged exposure to extreme cold and heat.
