Shock tests are used to accurately measure the durability
(or fragility) of various products, components, and to gauge the effectiveness
of protective packaging. Shock-test data is vital information necessary
to ensure that any product or component is capable of surviving in its
Types of shock tests include:
Damage-Boundary Product Fragility Assessment
Industry-standard shock pulse
Company-specific shock testing specification
Examples of shock-test systems and shock testers
are presented below:

shock control system from Lansmont.
The machine controller allows the operator to set up basic functions,
such as drop height, brake pressure, and programmer pressure. More
advanced set up features, such as shock pulse predictor and auto-cycle
functions are also included with the control system. Once the shock
test machine is properly set up, the controller interfaces with
Lansmont's TestPartner software for data
acquisition. TestPartner Windows-based software system includes
analysis tools, such as: Shock Response Spectrum (SRS) analysis,
FFT analysis, shock response animation in both 2D and 3D modes,
Shock Response analysis with programmable model Fn and damping, and tolerance band overlays with selectable Mil-Spec and programmable
This shock-control system may be used to control the shock
