HST-DWT-300IG Instrumented Drop Weight Impact Testing Machine
1.Application:
HST DWI-300G instrumented drop hammer impact tester is mainly used to test the puncture performance of anti-stab clothing. It uses impact force sensor, test system, and high-speed data acquisition card to measure the load and deformation transient value of the impacted sample fracture process through oscilloscope impact sensor, that is, impact absorption work, force-displacement-energy curve of the impact process and characteristic points on the curve: maximum force Fm, total impact energy Wt and corresponding displacement and other parameters.
2.Function
Test the puncture performance of stab-resistant clothing.
3.Implementation standard
GB/T2611-2022 "General Technical Requirements for Testing Machines"
