ISO 9854 Pipe sample impact tester

Charpy Impact is a single point test that measures a materials resistance to impact from a swinging pendulum. Charpy impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. The values obtained can be used for quality control or to differentiate general toughness.

ISO 9854-1 Specifies the general impact test method to be used for the determination of the impact strength of unnotched test pieces cut from thermoplastics pipes for the transport of fluids.

United Test product both the IZOD and Charpy impact tester, in dial display, LCD screen display and computer control used determine the impact ductility of nonmetallic materials, such as Rigid thermoplastic and thermosetting plastic, thermosetting plastic and thermoplastic after fiber-reinforced. It is widely used in the industries of plastic products, plastic manufacture, petro chemical etc, University, scientific research institute and commodity inspection department.

Charpy Test: The specimen is mounted horizontally and supported unclamped at both ends. The hammer is released and allowed to strike through the specimen. If breakage does not occur, a heavier hammer is used until failure occurs.
