This paper describes a methodology of small sample test technique for fracture toughness determination in the upper shelf region. The effect of size and strain rate has been investigated and described. Standard and small sized samples for 3-point bend test were produced and tested from several steels. The results is promising for further usage in many fields, where only limited amount of material is available, like residual life assessment, additive manufacturing industry, local properties determination in case of heterogenic material, etc. In addition, competitive methods like small punch test will be discussed as well.Keywords: Fracture toughness, miniaturized samples, Micro-Tensile Test, Digital Image Correlation (DIC)
