    Abstract. It is considered how the design of the sample during the impact bending tests affects the efficiency of evaluation of the visco-brittle transition of steels for building metal structures with different strength, as well as with different degree of dispersion of the structure and purity of the metal by harmful impurities and non-metallic inclusions. It is shown that the effectiveness of impact bending tests for assessing the fracture resistance of structural steels is due to the fact that such tests simulate the possibility of steel transition from a viscous state to a brittle state in the range of climatic temperatures. The main factors that contribute to the visco-brittle transition in steels and the minimum number of simultaneously acting such factors, deterministically providing a visco-brittle transition, and, in particular, acting in shock bending tests in the range of climatic temperatures are discussed. The conditions for ensuring the sensitivity of these tests to adverse changes in the microstructure are described. In order to ensure the required sensitivity, the issues of compliance with the principles of structural similarity in the tests are raised. It is explained that when the dispersion of the structure increases, the volume-stress state at the top of the cut should be toughened. The influence of the degree of contamination of the metal and the grain boundary density on the occurrence and propagation of cracks when testing for impact bending, as well as the requirements for compliance with the degree of grinding of the structure and improve the purity of the metal are considered. The necessity of using specimens with a concentrator in the form of a fatigue crack for the correct estimation of impact viscosity of modern steels with micron grain and high purity by harmful impurities is shown.
