Abstract
A drum testing apparatus simultaneously tests the bottom chine, sidewall vertical chine, and wall integrity of a typical drum, such as a 55-gallon drum. The apparatus includes a frame for supporting the drum to be tested in a generally upright position. A turntable base is moveably supported by the frame and provides a rotatable surface for supporting and turning the drum at its bottom end portion. A reservoir immerses the drum bottom chine and the top chine during testing and while the turntable base rotates the drum. A liquid spray simultaneously immerses the drum sidewall and the vertical chine during testing and while the drum rotates. A holder including a pair of spaced-apart flanged portions engages respectively the top end portion and the bottom end portion of the drum and preloads the drum end portions to prevent removal of the drum end portions during testing. An air pressure source pressurizes the drum interior during testing. Leakage is detected by bubbles appearing visually to an inspector as the entire drum outer surface is covered with water or a water and chemical solution during the testing procedure.
