Abstract

The method for determination of static hardness of wood includes pressing of indenter to wood under effect of static load. As indenter a cut at angle α to the side of the working blade three-facet prism with angle at the top β is used, its blade with width L at pressing to the sample is oriented with respect to the wood fiber at needed angles. The value of hardness is calculated with division of the value of load by the area of obtained imprint, at that the values of the angles α and β are chosen within (25-65)° and (30-90)°, respectively.
