JBDW -C Series Ultralow-temperature Automatic Impact Testing Machine
Application
JBDW-C type impact testing machine is used for measuring the metal material resistance performance under dynamic load, in order to determine the material properties under dynamic load. It’s a necessary testing machine, not only used in the metallurgy, machine manufacture etc areas, but also used for the science research.
Standards
ASTM E23, ISO148-2006 and GB/T3038-2002, GB/229-2007
