The invention refers to a mobile experimental stand for testing a linear structural element, with a length of approximately 1 ÷ 4 m, to temperatures of 600⁰C÷800⁰C. It may be used in testing various types of beams or columns to high temperatures. The stand presents versatility, the height of the burner and the distance between burners being easily set according to the user’s needs. Furthermore, the stand is simple enough to be disassembled and moved to other locations, thus reducing transportati
