Mechanical Impact Testing Machines

No модели : QC-639C、639D
Mechanical Impact Tester
Confirm to ASTM D256, ASTM D6110, ISO179, ISO180, ISO13802 Standard

QC-639C/D series tester can be used to determine impact resistance of polymers. It use the energy conversion to calculate the energy absorbed by the sample after impact. The precise of impact hammer will highly affect the center position of its mass and impact speed, which in turn influence the test accuracy. QC-639C/D uses pointer to record the angle after impact. It has a dedicated software to calculate and correction helping user to get the test result. Izod/Charpy is the most common methods. QC-639S/T can support to change the impact hammer and vise rapidly to satisfy different test condition and standards (ASTM & ISO).
