Impact Tests

Impact tests on complete pipe sections are usually performed with special non-instrumented drop-weight testers. 
 
Small pipe diameters, as frequently used in automobile construction, can be tested to ISO 7628-2 with a pendulum impact tester in a modified Charpy arrangement with a 7.5J pendulum. 
 
Impact testing or notched impact testing on specimens taken from the pipe wall can also be performed as a materials test using the Charpy or Izod test methods.
