Subsized Charpy V Notch Values
Subsized Charpy V Notch Values
(OP)
We have customer requirements that state we need to achieve CVN values of 27j @ -50 on weldments. Upon testing our weldments a testing lab used subsized samples (5mm x 5mm x 20mm), is there a mathmatic way to correlate the subsized CVN results back to a standard size sammple (10mm x 10mm x 20mm).

And yes I was confused on the standard size.

For carbon steels at that temperature, there is a substantial penalty for specimens that are 50% of full size.
