Shock, bump and impact testing

Impact by means of falling, bumping or colliding during the logistical trajectory and the life cycle of a product is normal. Shocks may severely damage the product with or without its packaging. Using an electric dynamical vibration table, a shock machine, an inclined plane tester and a HIT-machine, the shock resistance of a product or its packaging can be determined.

The controlled execution of an impact test, using known shock levels, is essential to determine the weakest links in a product or packaging. Using the results, the product or packaging can be optimized.

If a correct integration of the shock and drop requirements during the product design or the engineering is used, a drop or impact test will not be destructive, but prove ultimately that a product will survive a fall from a required height or shock. A good shock and vibration design will generally not result in a more expensive product. It will make the product more reliable and mostly lighter. The packaging volume will decrease as a result of less or no protective material, significantly lowering the packaging and transport costs.

Electric dynamic vibration table

Using this advanced technology, it is possible to execute shock and impact tests on one of our vibration tables following MIL STD 810 and IEC 60068-2-27 standards. The impact may be simulated vertically or horizontally. It is also possible to offer an SRS (shock response spectrum).


  • Test weight max.: 700 kg
  • Test direction: vertical and horizontal
  •  Dimensions table top: 1200 x 1200 mm
  •  Peak acceleration: 100 g
  •  Velocity: 2,5 m/s
  •  Displacement: 60 mm (peak-peak)

Shock bank

The standard ASTM D3332 describes, for instance, the ‘Step Velocity and Step Acceleration Test’ to determine the so-called ‘Damage Boundary Curve’. The D-Bound curve shows up to which critical acceleration and velocity changes the product will incur no damage as a result of a shock or drop. A variety of half-sinus shaped, block and saw tooth pulses can be achieved.


  • Test weight max.: 1.200 kg
  • Test direction: vertical
  • Dimensions table top: 1200 x 1200 mm
  • Peak acceleration: 1.200 g
  • Velocity: 6 m/s (possible to increase to 10 m/s)
  • Displacement: 2.000 mm

Horizontal inclined impact test

ASTM D 5277 and ISO 2244 describe, amongst others, a horizontal impact test of colliding a pallet using a certain speed with a 13 mm thick steel wall. This simulation shows the stability of the pallet during transport. Imagine a truck braking hard (<0,8 g) - it will be nice to know that your pallet is still upright.


  • Test weight: 2.000 kg
  • Test direction: horizontal (inclined to 10 degrees)
  • Dimensions table top: 1500 x 1500 mm
  • Velocity: 4 m/s

Horizontal shock test (also known as HIT machine)

ASTM D 4003 and various ISTA procedures describe a horizontal shock test in which a pallet must endure an impact of fifteen milliseconds and a velocity of 0,9 meters per second.


  • Test weight: 2.000 kg
  • Test direction: horizontal
  • Dimensions table top: 1500 x 1500 mm
  • Velocity: 2 m/s
  • Puls duration:

Data acquisition

Measuring shocks is done using a Lansmont SAVER, LAB Equipment Analyser and with Dactron control/analysers. This equipment registers and analyses the measured acceleration signals and the matching timeframe.

Integration of shock and vibration requirements in the design will result in lower costs for packaging. Guaranteed.
