Drop Weight Impact Testing Machine(30000J~100000J)
Application
DWTT series is mainly used for drop weight tear test (DWTT) of Ferrite Steels, to observe specimen fracture surface after impact within the temperature that fracture type is converted from non-ductility to ductility. This test method is that the hammer striker with weights is raised to a specific height then released. Free drop hammer impacts and tears the specimen. After the impact, proportions of ductile fracture (shear) and cleavage on the fracture surfaces are measured.
This testing machine complies with the relevant requirements of standards for DWTT such as metallic materials Drop-weight tear tests of ferrite steels.
Standards:
API RP 5L3 (recommended),ASTM E 436,EN 10274,GB 8363,ASTM E208
