ASTM: Doubts regarding impact energy in impact tests
Thread Content
As the title suggests, why are there so many different values corresponding to the impact energy of impact specimens in small size categories? Which one should be taken as the standard?
If it is not possible to use full-size impact specimens, smaller specimens can be used as a substitute. Determine what is the largest impact specimen that can be manufactured based on the properties of the material, and then decide whether to use smaller specimens
For each small test sample pair, with multiple impact energies available, which one should be chosen?

So can the impact test only be conducted using one of the torques or initial values listed?
@Niata8888, teacher, please come and give your comments
The acceptable criteria for the specific impact energy and the temperature for the impact test shall be in accordance with the provisions of the relevant material standards.

I don’t understand what his confusion is about. . .
