IEC EN 61386 and PMA DO 9.21-4330 describe tests to evaluate the resistance of conduits to high energy impacts.
They can be performed on conduits at various temperatures. Weights of different mass are dropped from an adjustable height directly onto a conduit sample which has been conditioned at the specified temperature. The energy of impact can be calculated as mass x gravity x height. The geometry of the object falling onto the conduit is regulated. No breaks, cracks or excessive permanent deformation should be visible after the test.
