    Statistical analysis of the variability of crack-arrest toughness (Ka) is reviewed. The standard deviation of Ka is 12 MPa · m1/2 for an individual heat of low-alloy steel and 15 MPa · m1/2 when data for all heats are referred to the Charpy 41-J (30 ft-lb) temperature. These results aid in the definition of acceptable size limitations for crack-arrest test specimens. Miniature specimens (50 by 50 by 12.7 mm) are shown to give acceptably conservative results when tested in the vicinity of the reference transition temperature.
