    This contribution deals with the determination of the reference temperature of JRQ steel using miniaturized
    specimens. The dimensions of the miniaturized specimens used were 3 × 4 × 27 mm (thickness × width ×
    length). This specimen type allows utilizing a limited amount of test material or the broken halves of pre-cracked
    Charpy or larger specimens. The test material comes from the broken halves of 0.5T SE(B) specimens
    previously tested for the determination of the reference temperature at Ciemat, Madrid. The fracture toughness
    tests were performed in the transition region of the steel according to the recommendations of the standard
    ASTM E1921 and according to Wallin’s recommended temperature range of miniaturized specimens. The
    reference temperature of the Master Curve was very similar to the ones obtained from three-point-bend
    specimens of sizes 0.2T, 0.4T and 0.5T. The results obtained confirm a necessity to conduct tests at low
    temperatures and to test a sufficient number of specimens in order to generate enough valid data for the
    determination of the reference temperature.
