Material deformation testing stand (1) for the long-term monitoring of deformation characteristics under constant pressure which consists of a base (2) in the form of a frame with a supporting frame (3) rising from one end, at a distance from it there is a positioning frame (4), and further it consists of a weight bearing arm (9) rested on said supporting frame (3), wherein the weight bearing arm has on one end a pivot (15) for a swinging connection with at least one tie rod (14) which has on its other side another pivot (16) for hanging onto a pressing arm (6) arranged approximately parallel to the weight bearing arm (9) and the exerting arm (6) is held in position by a pivot (16) and also by a horizontal pivot (13) located on the positioning frame (4), wherein the horizontal pivot (13) is arranged at a distance from the free end of the exerting arm (6) and between the free end of the exerting arm (6) and the base (2) is a space for arrangement of a measurement assembly (17) with the test sample (20) on the supporting block (18).
