Variations in Charpy impact data evaluated by a round-robin testing program -- A summary
- Lowe Associates, Lynchburg, VA (United States)
A round-robin type test program was designed to quantify some of the variables associated with Charpy impact test data. Each participant tested pre-machined specimens at each of six designated test temperatures. The data were evaluated using several techniques normally used to determine transition region temperatures and upper-shelf energies. These data were interpreted statistically to determine mean values and standard deviations. Variations in data appear to be more a factor of the specimen location within the material than related to test temperature. The variations in the data between the different testing participants were within the limits commonly observed. The expected erosion determining the 30 and 50 ft-lb transition temperatures and the upper-shelf energies were found to be independent of the evaluation technique used.
