Hualong WCJ Series is mainly used for drop weight tear test (DWTT) of Ferritic 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 striker with some weights is raised to some height then released. Free drop striker impacts and tears the specimen. After impact, observe shape and features of fracture surface.
This testing machine accords with the relevant requirements of Standards for DWTT such as: Metallic materials－Drop-weight tear tests of ferritic steels (GB8363-87), ASTM E604, Metallic materials－Dynamic tear testing method (GB5482－93), ASTM E 436-1991(Re1997) and APIRP 5L3-1996.API-5L3, EN 10274, ASTM-E 436
Capacity: 30000J/40000J/50000J
