JBN-300 IZOD Impact Testing Machine

1.Usage 
JBN-300 IZOD Impact Testing Machine is used to measure metal materials impact resistance performance under dynamic load, in order to judge the nature of the material under dynamic load.

This machine is semi-automatic testing machine, easy to operate and high efficiency. They can make use of spare energy to raise pendulum automatically and be ready for next impact test, can carry out the impact test continuously. It is widely used in the laboratory, metallurgy, machinery manufacturing industry, etc.
It correspond these standards:

1. ISO R84 

2. B·S 131 part 4 

3. GB4158-84 

Reference scale:GB4158-84“Metal airy impact testing method”.

The max. Impact force is 162J, Sample: Square cross section is 10*10mm; Circular cross section isΦ11.43.
