<P>PROBLEM TO BE SOLVED: To solve a problem wherein the corrosion caused by the adhesion of flying salt particles in the natural environment can not be reproduced, and the irregularity of atomizing is yet large at the same time in conventional testing equipment for testing the acceleration of atmospheric corrosion and the irregularity of the adhesion amount of salt particles in a testing tank can not be controlled. Ž<P>SOLUTION: The acceleration test of atmospheric corrosion is achieved by this testing equipment for testing the acceleration of atmospheric corrosion controlling the diameter of the liquid droplet of salt water to be bonded to a testing target and the adhesion position of the liquid droplet and capable of uniformly adhering the liquid droplets of salt water to the testing target without flocculating the liquid droplets of salt water attached to the testing target. The testing equipment for testing the acceleration of atmospheric corrosion is concretely constituted of: a thermostatic and humidistatic tank; a corrosion testing target stand on which a corrosion testing target is placed; a washing mechanism; and a salt water discharging mechanism for atomizing the salt water to the corrosion testing target. The relation between the diameter (r) of the liquid droplet of the salt water and the diameter (R) of the liquid droplet controlled by the salt water discharging mechanism is r≤1.1R, and the relation between the interval (L) between the liquid droplets attached to the surface of the corrosion testing target, and the diameter (R) of the liquid droplet controlled by the salt water discharging mechanism is of an interval of L≥1.2R or more. A predetermined amount of salt water is attached to the surface of the corrosion testing target per a unit area. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
