Apparatus for performing weather resistance test

An apparatus for performing a weather resistance test on a composite material having a metallic, inorganic or an organic base member and an organic material covering the base member, comprising:

• sample holding means disposed in a sample chamber for holding a sample of said composite material;
• irradiating means including an artificial light source for irradiating light substantially in the ultraviolet light area to one surface of said sample;
• dipping means for holding the sample in a horizontal position and applying a corrosive ionized aqueous solution selected from the group consisting, of salt, acid and alkali in a liquid state to said sample causing the aqueous solution to stagnate for a predetermined period of time;
• dew condensation means including temperature control means disposed in said sample holding means and moistening means disposed in said sample chamber for causing dew condensation on said surface of said sample;
• cleaning means for cleaning said surface of said sample;
• steaming means including heating means disposed in said sample chamber and said moistening means for steaming said sample in an atmosphere of high temperature and high humidity;
• and
• control means for controlling execution of operations of said irradiating means, said dipping means, said dew condensation means, said cleaning means and said steaming means in a predetermined manner, wherein said control means is adapted to sequentially execute a first step in which the operation of said cleaning means is conducted after the operation of said irradiating means and the operation of said dipping means is conducted after the operation of said cleaning means, a second step in which a second operation of said dipping means is conducted after the operation of said dew condensation means, and a third step in which the operation of said irradiating means is conducted after the operation of said steaming means.
