The applications of toughness scaling diagrams for correction of fracture toughness data in regime of constraint loss have been followed. The applications included adjustment of invalid data from standard specimens and correction of fracture toughness values generated by pre-cracked Charpy type specimens (P-CVN). Standard three point bend specimens have been tested to get the reference values. The Dodds-Anderson toughness scaling model was applied for toughness data correction and transfer from P-CVN specimens being combined with master curve methodology for fracture toughness - temperature diagram quantification. Local parameters, Weibull stress and parameter of scatter have been applied for another toughness scaling diagram calculation. Also in this case good correlation of predicted data with the real fracture behaviour has been found.
