Charpy Impact Testing
Charpy Impact Testing
(OP)
Dear respected members,
your clarification regarding the phrase "full scale" in the following paragraph taken from ASTM A 370 – 03a, would be much more appreciated.
22.2.2.1 For flat material less than 7⁄16 in. (11 mm) thick, or when the absorbed energy is expected to exceed 80% of full scale, use standard subsize test specimens.
Thanks in advance.
