Abstract
We report the results of the second Charpy Interlaboratory Comparison between NIST (National Institute of Standards and Technology, Boulder, Colorado, USA) and ATMS (Anand Testing Machine Services, Kabnur, India). The first comparison was run in 2022, and was described in NIST Technical Report 2243. Both studies involved testing in both locations Charpy reference specimens, certified and produced by both Institutes at different levels of absorbed energy. Test results obtained at NIST and ATMS were compared using the same machine configuration (C-type hammer) and striker type (2 mm), and statistical methods (unpaired two-sample t-test) were employed to assess the significance of interlaboratory differences.Citation
