ABSTRACT:
A spray corrosion test apparatus comprising an open topped test tank and a lid to cover the top of said test tank, said test tank having provided around the top edge of the side wall thereof a groove between the inner and outer surfaces of the wall thereof, said groove being adapted to receive the edge of said lid, the portion of said side wall defining the outer surface of said groove being higher than the inner surface, said groove being filled with a flexible porous insert of a water absorbing material up to the level of said inner surface. When said insert is sufficiently wetted with water, the tank and lid form an improved seal and the environment within the tank is resistant to fluctuation thereby providing test data of excellent reproducibility.
