FIELD: test engineering.
SUBSTANCE: device comprises a lower base, a stack of test annular specimens mounted on it with a common central opening, a support, a means for clamping, a means of monitoring the condition of the test samples. The device also comprises an upper base with a central threaded opening which is coaxial to the opening of the lower base, in which the loading screw is mounted, which clamps the stack of samples through the support. The upper base is connected to the lower by means of elastic elements with applied resistance strain gages connected to the input of strain-gauge means of monitoring the stress condition of the samples.
EFFECT: enhanced functionality, improvement of the effectiveness of the monitoring of process of degradation of protective coverings which are under conditions of aggressive environment.
