Product Serial : QC-639C、639D
Mechanical Impact Tester
Confirm to ASTM D256、ASTM D6110、ISO 179、ISO 180、ISO 13802 Standard

QC-639 series tester can measure the impact resistance of polymer materials. It calculates the absorbed impact energy based on the energy conversion relation. The precision of the impact hammer will highly affect the speed and mass position when impact, and this might influence the test accuracy. QC-639C/D uses a pointer to record the impact angle. The dedicated software can support calculating and correcting the test results for users. In this kind of test, Izod and Charpy are the most common test methods. This machine can change the hammers and vises rapidly to satisfy different test methods and standards (ASTM & ISO).
