Pendulum Impact Testing Machine
Pendulum impact testing machines, also called Charpy impact testers, measure how much energy a metal can take before breaking from a sudden blow (impact). During the test, a notched specimen rests horizontally on two supports while a weighted pendulum swings down and strikes it.
Standards: GB/T, ISO, ASTM, JJG -
Pendulum Impact Tester (for DWTT & DT Tests)
Pendulum impact testers for DWTT and DT testing are high-energy instruments designed for larger and thicker metal specimens than those normally used in Charpy tests. The pendulum impacts the notched specimen at high speed and causes it to break with one blow.
Standards: GB/T, ISO, ASTM, JJG -
Charpy & Izod Pendulum Impact Tester for Plastic
Charpy and Izod pendulum impact testers measure the way in which plastics and other non-metallic materials react when struck by a sudden blow/impact. In these tests, a pendulum which has been released from a certain height hits the specimen, and the amount of energy it loses as a result of the impact indicates how much energy the material has absorbed before it breaks.

NDT Drop Weight Impact Testing Machine
NDT drop weight impact testers determine the nil-ductility transition temperature of ferritic steel, which is the highest temperature at which a standard specimen still fractures in a brittle manner under specified impact conditions.
Standards: GB/T, ISO, ASTM, GOST, EN -
DWTT Drop Weight Tear Tester
DWTT drop weight tear testers are mainly used for ferritic steel plates and line-pipe steels to determine whether a crack will continue to grow after a sudden impact. During each test, a full-thickness notched specimen rests on two supports.
Standards: GB/T, ASTM, EN -
Instrumented Drop Tower / Falling Weight Impact Tester
Instrumented drop towers, or falling weight impact testers, are used when more than a simple pass/fail result is required. The guided weight drops from a set height, so the striker hits the specified point on the specimen.
Standards: GB/T, ISO, ASTM, EN -
Drop Weight Impact Tester for Plastic
Drop weight impact testers for plastics measure how well plastic sheets, pipes, and other specimens withstand a sudden impact. To perform the test, a striker of a specified weight is raised to a particular height and then allowed to fall, moving down the guide columns before hitting the specimen underneath.
