Introduction：
Weatherproof test: This test is conducted to find out the impacts on some items and parts in a natural condition by such factors as sunbeam, ozone, rain, snow, temperature and humidity. It will also find out the resistance of the aforesaid items to the aging effects imposed on them by the elements. The changes of properties of the items under test such as deformation, discoloration, rate of penetration, gloss, peeling, hardness and softness maybe found out easily in a short time. With the result of the test, the quality requirement may be improved. This test device may be used in many fields such as aviation, coating industry, automobile industry, textile industry, dyestuff industry, plastic industry and construction companies.
