Tests were conducted to compare the regular type ASTM Designation B117-54T salt spray cabinet using the conventional salt solution aspiration mechanism with the new Fog Dispersion Tower Conversion Kit means of salt-fog emission. Tests indicated that better fog distribution and less consumption of solution result from the use of the conversion tower type equipment. Collection rate data obtained by placing collection funnels at certain positions, or stations, proved this to be true. The ASTM designated B117-54T equipment sometimes fails to complete a full week-end of operation 64 hours, while the Conversion Tower-Type apparatus operates for 96 hours or more before the solution supply is exhausted. It was found that practically no reduction of the quantity or quality of the fog in the collection graduates resulted as the solution level in the supply tank decreased. Author
