materjali sitkuse määramine Charpy meetodil, mille korral sälguga või sälguta horisontaalselt kahele toele paigutatud teimikule rakendatakse löökkoormus (vt löökpaindekatse; vrd Izod löökpaindekatse), a flexed beam, notched-specimen impact test in which both ends of notched specimen are supported and a stricker carried on a pendulum impacts the specimen centrally on the face opposite the notch; the energy absorbed in fracture is then calculated (see: impact bending test; compare: Izod impact test)
