FIELD: testing.
SUBSTANCE: invention can be used for testing and adjustment of flaw detectors of eddy current and magnetic flaw detection. Control sample for eddy current and magnetic flaw detection, having the form of a round metal disk with a central hole and containing artificial defects extending to at least one of its end surfaces, is equipped with a shaft passing through the central hole of the disc, installed coaxially with it and fixed relative to the disc, wherein the artificial defects are made in the form of notches on the end surface of the disc in the radial direction, oriented along the planes passing through the axis of the central hole, displaced relative to each other along the angular coordinate by a monotonously increasing value, and the shaft is made with an inner cavity throughout its length.
EFFECT: enabling testing and adjustment of eddy current and magnetic flaw detection facilities in dynamic mode.
