Abstract
Results are reported of an Interlaboratory Comparison between NIST (National Institute of Standards and Technology, Boulder, Colorado, USA) and ATMS (Anand Technical Machine Services, Kabnur, India). The study consisted in testing in both locations certified Charpy reference specimens produced by both Institutes, corresponding to four different absorbed energy levels (18 J, 60 J, 108 J, and 150 J). Besides directly comparing test results obtained with the same machine configuration (C-type hammer and 2 mm striker), the use of a different hammer (U-type) and striker type (8 mm) at NIST allowed to get some insight in the influence of hammer and striker types on Charpy test results.
