It is a common practice to conduct periodic washes at designated intervals in order to prevent the atmosphericcorrosion of aircraft. The wash interval depends on the atmospheric conditions, but the wash intervals set bythe U.S. Air Force were widely adopted in Korea without detailed knowledge of the background data. Therefore,it is necessary to determine our own wash intervals representing the atmospheric and geographical conditionsin Korea. This study analyzed previous wash interval algorithms and atmospheric data in Korea. New wash intervalsare then proposed based on the corrosion rate equation in ISO-9223:2012. Atmospheric corrosion testing wasconducted using 7075 and 1050 aluminum alloy specimens to verify the accuracy of the corrosion rate equationin ISO-9223:2012. Test results showed a reasonable agreement with the corrosion rates predicted by the equation.
