Abstract:
1. A testing apparatus, comprising a reservoir configured to contain a solution; a stationary test tank fluidly coupled to the reservoir and configured to contain a test specimen and receive the solution from the reservoir; a fill pump configured to pump the solution from the reservoir to the test tank; and a drain valve configured to drain the solution from the test tank and into the reservoir; a sequence controller communicatively coupled to the fill pump and the drain valve and configured to provide sequence timing for the activation and deactivation of the fill pump and drain value to alternately fill and drain the test tank to alternately immerse the test specimen during an immersion time period and allow the test specimen to dry during a drying time for a repeated number of immersion and drying cycles, the sequence controller closing the drain valve after the test tank is drained of solution and maintaining the fill pump in a deactivated state during each drying time period prior to reactivating the fill pump for refilling the test tank to re-immerse the test specimen during each immersion time period.
