FIELD: testing technology.
SUBSTANCE: impact bending tests of prismatic samples are carried out, which have a notch with the record of the destruction curve in the coordinates of load-offset of the striker by identifying of characteristic points on it. On the destruction curve obtained the linear dropdown site is isolated, the values of load FH, FK and offset SH, SK are identified on it, corresponding to the beginning and the end of this stage of destruction, the area under the selected site is determined, and the level of viscosity KB is determined by the formula.
EFFECT: ability of determining the characteristics of viscosity for validation of under-broken samples.
