FIELD: mechanical engineering; testing of metal parts. SUBSTANCE: invention relates to making of specimens for mechanical testing of steel pipes, cylinders and other cylindrical articles for impact bending. Specimen is cut out of article square to its axis and stress concentrator is formed on specimen. Specimen is made curvilinear, with bent off ends. Section of specimen on its working length corresponds to curvature of article, and support sections on ends of specimen and point on axis of symmetry of specimen corresponding to half of its thickness are located in one plane. EFFECT: provision of specimens whose test results provide reliable information on impact viscosity of articles. 3 dwg
