Abstract
Provided are an apparatus for testing a tensile strength under a high temperature condition and a unit for measuring elongation provided in the same. The apparatus for testing a tensile strength under a high temperature condition includes a base frame part, a test sample loader and a cylinder part connected to the base frame part and applying a tensile force to a test sample, and a heater for forming a high temperature condition to the test sample. The unit for measuring elongation includes a movable frame, a vertical bar, and a measurement head part connected to the vertical bar to measure elongation of the test sample and blocking heat from the heater. Therefore, since a tensile strength and elongation of the test sample can be measured under a high temperature condition, it is possible to recognize deformation characteristics of a material due to a fire and prevent deformation of or damage to the elongation measurement unit even under the high temperature condition, improving durability and reliability of the apparatus.
