Comparison of Charpy's at different energies and temperatures
Comparison of Charpy's at different energies and temperatures
(OP)
Is there any way to compare V Notch Charpy tests?
The commonly available steel (to BS EN 10025) is tested at 27J at -20 degrees. The design code requires 35J at -5 degrees. Is there an approximation which would allow you to say that a 27J impact at -20 deg would similar to a ??J at -5 deg?
We have a materials department who will ultimately resolve this and probably get it tested but I wondered if there was a go by which is used as an indication. This is for my own benefit more than anything else.

Now if it met 35J at -20 you would be home free.
