Methods and devices for in-situ establishment of mechanical properties of wood have been recently developed in cooperation of Czech and US researchers. The development of new methods was motivated by requirements from engineers who need most accurate data of mechanical properties of specific elements when planning renovations of historic buildings. The established data replace mean standard values of strengths in their static calculations, which results in the demanded possible retaining of a larger amount of original material as the behaviour of the specific elements is safely assessed. The newly developed methods, which are described in this chapter, are tensile strength of small samples, compression strength of cores, compression strength in a drilled hole, and mechanical resistance to pin pushing. Although the devices for the testing of mechanical properties by the mentioned methods provide more accurate results than the methods used so far, they are not mass produced, which should change soon.
