In this paper is presented the 1-point method for material behaviour prediction, in terms of fracture toughness,
of the ferritic steel EN 1.6310 in the transition temperature regime (-60°C and -90°C). Experiments were carried
out at two different temperatures, representing two studies joined in one. Experimental testing was perfomed
according to ASTM 1820 standard. This 1-point method is based on statistical processing (of 2-parameters
Weibull statistics) of obtained experimental results, i.e. scattered J-integral values, of C(T) specimens with
different geometries. Fixing value of one Weibull parameter and taking into account size-dependence of
second one, fracture probabilities in the function of J-integral for large C(T)100 and C(T)200 were determined
based on testing of C(T)50 specimen size. This research pointed out the sensitivty of proposed method on
statistical sample size. One of the aims of proposed method was reducing the cost and price of laboratory
tests in overal...l by predicting material behaviour and testing smaller C(T) specimen size. This research
represents an upgrade of the Landes and Heerens works, and it is dedicated to their efforts in understanding
and characterisation of transition temperature regime of ferritic steels.
