This paper reports the summary of JIc test procedures based on an ultrasonic method proposed earlier. The single-specimen JIc measurements for low- and intermediate-strength, high-toughness materials show excellent agreement with those determined by multispeciment test procedures. The JIc values of the weldment were also determined from a single specimen. In addition, a statistical analysis of the JIc distribution was done.
