FIELD: testing engineering.
SUBSTANCE: method comprises setting the rod on three supports. The center of symmetry of the rod is set on one of the supports. The two other supports are positioned at the same distance from the first support. The first support receives the receiver of acoustical signals. The two other supports receive strikers. The acoustical signal generating by each striker is analyzed in the receiver. The analysis is divided into time intervals which allow the analysis of the condition of each part of the rod, including its heads.
EFFECT: enhanced reliability of testing.
