1. 1.     Usage and features

l       Mainly used to test the capacity of impact resistance under dynamic load for metallic materials，in order to determine the property of the materials under the dynamic load.

l       Automatically swing with remaining erengy after impact test, easy to operate, highly effective, reliably, especially suitable for laboratory with successive impact tests and metallurgical and mechanical manufacture industries with lots of impact tests.

The series of impact testers are designed according to national standard GB/T3808—1995 Pendulum Impact Tester，doing impact test to metallic materials according to GB/T229—1994 Metal Charpy Gap Impact Test Method.
