Product Description

1.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

2. Standards

ISO148-2006, ASTM E23, GB/T3808-2002 ,GB/T229-2007

3. Features :

3.1 Cooling by liquid nitrogen refrigeration

3.2 Which adopts PC computer control, this machine can auto-complete the following actions: rising pendulum, hanging pendulum, sending specimen, positioning, impacting,temperature conditioning

3.3 After impacting the specimen, the machine can raise pendulum with surplus energy automatically so as to be ready for the next test

3.4 PC machine can display material impact absorption power, impact toughness, pendulum raising angle and test average value, and can print the test data and the average value of the test.
