Description	In this paper J-R curves were measured with Charpy size SE(B) and C(T) specimens of P91 steel using the unloading compliance technique. The fracture toughness parameters were determined according to the test standards ASTM E1820 and ISO 12135 and whose evaluation differences and validity criteria were assessed. Despite the available sophisticated instrumentation used for obtaining the J-R curves and strict implementation of the recommended test procedure, a scatter in the initial portion of the curve is persistent. This creates problems in the evaluation of the measured J-∆a values and in obtaining valid and unambiguous JIC and J0.2BL values according to both standards. The influence of these scatter on the fracture toughness values is discussed. Accompanying fractographic studies were performed to assess the J-R curves and to determine the SZW.
