Abstract
A procedure of the pulse echo-mirror method for testing rods by Pochhammer waves that uses multiple reflections of the transmitted pulse from flaws and free end faces of these rods is presented. It is shown that the sensitivity of the method can be increased considerably. The experimental studies of multiple reflections from an artificial flaw are confirmed theoretically.
