IZOD & Charpy Impact Tester

Impact strength is often used to evaluate the ability of materials to resist impact or to judge the brittleness or toughness of materials, which is an important performance index of plastic materials in engineering applications. It reflects the ability of different materials to resist damage caused by high-speed impact. When measuring the impact strength of plastics, the commonly used test methods include the IZOD impact method and the Charpy impact method. There are two types of notched impact and unnotched impact in these two methods. What we will introduce here is the Charpy impact tester.

Charpy Impact Tester is intended to determine the Charpy impact strength of hard plastics, fiber reinforced composites, glass fiber reinforced plastics, ceramics, asbestos and other non-metallic materials under specified conditions. It is capable of mastering the behaviour of stipulated kinds of test pieces under the impact conditions and estimating the brittleness or toughness of test pieces within the limitations inherent in the test conditions. The determination of comparative data from similar kinds of material is available via this equipment. It is an ideal testing instrument for manufacturing industries, research and development institutions, colleges and universities, and quality inspection organizations.

Before the test, a simple calibration of the instrument without placing the specimen is conducted for the resistance of friction and wind. The hammer is released electronically by a solenoid during the test under the operator’s control. Different impact velocities of 2.9 m/s and 3.8 m/s are available by choosing different types of pendulum ranging from 1 J to 50 J. A PLC controller coupled with a touch screen facilitates the parameter setting and data monitoring, including impact energy, impact velocity and sample size, etc.
