Popis:	Statistical analyses were conducted by using the cyclic crack growth rate data for pressure vessel steels stored in the JAERI Material Performance Database (JMPD), and comparisons were made on variability and/or reproducibility of the data between obtained by Δ K -increasing and by Δ K -constant type tests. Based on the results of the statistical analyses, it was concluded that Δ K -constant type tests are generally superior to the commonly used Δ K -increasing type tests from the viewpoint of variability and/or reproducibility of the data. Such a tendency was more pronounced in the tests conducted in simulated LWR primary coolants than those in air.
