Impact energy acceptance criteria
Impact energy acceptance criteria
(OP)
ASTM A370 specifies a range of impact energies that can be used as an acceptance criteria for a Charpy impact test. How do you decide what impact value to use for a particular specimen size? Some material specs state the impact energy acceptance criteria and temperature that the test has to be performed at, but others don't.
I'm generally looking at stainless steels such as A479 316 and carbon steels such as A352 LCB.

RE: Impact energy acceptance criteria
It has nothing to do with acceptance levels.
If you have a steel that requires testing at -40, and a 20lb-ft min, but you can't get a full size sample then you use this table to tell you what that translates to for a 1/2 size sample.
