PURPOSE: A testing device is provided to accurately measure a stress applied to a sample with a load cell, thereby immediately measuring a fracture of a sample. CONSTITUTION: A testing device comprises a base(10), a container(20), a cover(30), a supply flow path unit(40), a fixing unit(50), and an extension unit(60). The base comprises a first through-hole where one side of a sample penetrates through. The container comprising a space is seated on the base. The cover comprising a second through-hole where the other side of the sample penetrates through, a gas inlet, and a gas outlet is seated on the container. One side of the supply flow path unit is connected to the gas supply unit and the other side of the supply flow path unit is connected to the gas inlet, thereby supplying gas to the container. The fixing unit comprising a load cell measuring a stress applied on the sample is joined to one side of the sample, thereby fixing the sample. The tensile unit is joined to the other side of the sample, thereby stretching the sample. |
