Bump Tester
The purpose of bump test is to know when the specimen encounters repetitive mechanical-hit environment, the accumulation of its damage and degradation of specific functions. It also can be used to assess the structural integrity.

This bump test is to simulate the possible repetitive impacting effects that the equipment and components in the transporting process; it is mainly testing for the non-packaging or carton-packed specimens. For the latter case, carton shall be tested together with the specimens.

During test, the test specimens are usually fixed to the fixture or on the shock tester’s platform; and use the repetitive half-sine wave to impact the specimens. Duplicated frequency of a half-sine wave, wave peak and the holding time will follow the requirements specified in the relevant specification.
This tester complies with IEC-60068-2 test specification.
Easy in installation and operation; no maintenance required; function holds long.
Resonance-free structure; air bellow anti-vibration pad can effectively isolate floor vibration.
Accelerometer feedback measurement; adjustable half-sine wave generator; data control is precise.
TAF-certified lab and two decades professional in design & production; worth for your trustfulness.
