Good evening. Are you aware of any table/method of conversion between the values obtained from charpy resilience tests?
my problem lies in the fact that the norms en 13445-2 define the minimum resilience of the material with charpy samples cut to v, without specifying anything else. but in the reference standard for these tests, the uni en 10045, the default test is 10x10 mm, and it is provided, always for the v inlet, sections reduced by 7.5 and 5 mm, firm remaining the other dimensions and the carving. so from what I understand the values reported in 13445 refer to the test 10x10.
of course the resilience values made with 10x10 or 7.5x7.5 differ considerably and substantially, in particular the values obtained with the first are much higher, and for some materials makes the difference in being able or unable to use it, considering the measured value in absolute terms.
However, the size of the test results from my mechanical details does not allow to obtain the 10x10, but only the 5x5, hence the question: is there a way to convert resilience measured on a 5x5 to what you would get on a 10x10?
the norms are not reported. or maybe I didn't find it
