This paper highlights the shortcomings of flexural testing at high temperatures and stresses the necessity to resort to uniaxial testing for reliable data generation. The parameters to define and quantify bending in a uniaxial test setup are reviewed and a procedure to measure the maximum amount of bending along the gauge length of a uniaxial testpiece is described. The alignment performances of two uniaxial loading setups developed in-house are presented. The factors to consider when testing at high temperature are discussed and a set of recommendations for reliable uniaxial testing at high temperature is formulated.
