    Abstract: Provided are an atmospheric corrosion test procedure and an apparatus used for the test. The procedure involves a salt spray step for supplying salt content containing chloride ions on the surfaces of test pieces placed in a thermo-humidistat chamber and a subsequent dry-wet cyclic step including a dry sub-step for drying the surface of the test pieces in the thermo-humidistat chamber at a low relative humidity and a subsequent wet sub-step at a higher relative humidity than that in the dry sub-step, which are cycled. The salt content is supplied by spraying the salt water in the salt spray step. An exhaust step for removing the salt mist sprayed inside thermo-humidistat chamber is further inserted between the salt deposition step and the dry sub-step. The quantity of the salt content deposited on the surfaces of the test pieces is controlled by adjusting the quantity of the sprayed salt water.
