Hello All,

One of our locations is putting in some mechanical test equipment for an Internal Lab. They currently have a T-O to do Yeild, Tensile, & Elongation tests and a Rockwell hardness tester. They are looking into acquiring the equipment to do their own Charpy Testing. Does anyone in the forum have a procedure or work instructions they would be willing to share on Charpy testing?

Also see the attachment, a NIST document that might be helpful.

Hi Jim,

Great link. I had not seen that NIST Special Publication.

ASTM E 23 referenced in the NIST PDF is the standard that we used. You can buy the NIST Charpy calibration standards directly from NIST. I recommend keeping two sets for each of the ranges, and ordering well in advance of your next calibration due date.

great resource, Jim.

my suggestion to the OP is to use this, the ASTM standards, and your specific machine training/operating manual to come up with a specific work instruction/training plan for operations.

great resource, Jim.


Thanks; I got it from my good friend Mr. Google.
