Testing standard impact test

Dear imechanicans,
I am starting to do charpy test on a fiber composite and I am wondering about the testing standards. (because I dont wont to choose a wrong geometrie).
The problem is: the given sample is a hollow tube with a given wall thickness.
Do you have any ideas on which testing standrads my analysis should be based on?
Or what should I pay attention? (because it is not a standard sample)?
THANKS

hi, there are several ASTM
hi, there are several ASTM standards cover this topic. Check out ASTM E23, ASTM A370. The size is (in mm) 10x10x55, 2 mm depth 45 deg V-notch, root radius 0.25 mm.
you will probably get different results if you are talking about cutting a specimen from a thick pipe in the hoop and longitudinal direction.
