During a product’s distribution cycle, impacts and shocks are some of the hazards that can compromise its safety. By using a shock testing machine, it is possible to forecast the effect of these hazards on the package and goods, and design a packaging that is able to protect the load.
Which companies develop shock testing methods?
Shock testing methods are essential for many companies that see the safety of their products threatened by various situations that take place during transportation: Rough Handling, Pallet marshalling and rail car switching are some of the processes where impacts can compromise the goods.
By using shock testing equipment they can avoid the effect of these impacts and optimize the transportation packaging accordingly.
Furthermore, it is possible to perform shock testing methods to test the stability of a product, and how it behaves during shipping & handling, analyzing their weak spots.
How to perform an impact test, step by step
Shock testing methods are included in all package testing protocols.
International regulations and standards such as ISTA, ASTM, ISO and MIL STD establish different procedures for the performance of these tests.
Generally, the procedure involves the following steps:
- The load to be tested is placed on the testing platform of the shock testing machine.
- The impact velocity is selected.
- The test is executed.
- The load impacts the impact surface.
- Damages to the load are evaluated.
- The test is repeated as many times as required and for all necessary package faces.
Some protocols require the load to impact a specific obstacle, such as the forks of a cart. In this case, it is possible to secure a fork-shaped implement – or other obstacles specified in the testing protocols – to the impact surface.
In addition, the most advanced shock testing equipment allows for the control of the impact wave, which may be sinusoidal or trapezoidal. This type of test, which requires advanced knowledge, is common in technology institutes or testing laboratories.
What shock testing machine do you need?
Safe Load TT has developed two machines for performing mechanical shock tests.
In both cases it is possible to modify the impact surface by adding several implements as outlined in different regulations and cases (such as, for example, the forks of a cart).
The incline shock machine
This incline shock simulation system simulates the horizontal shocks and impacts that affect the stability and safety of a load during shipping & handling.
It uses the force of gravity to perform the test. In this case, the platform that will carry the loads slides along rails on an incline, offering a maximum impact velocity of 2.5 m/s. This speed can be increased if required by the client.
There are four standard models of incline shock machines to choose from depending on the maximum test load that they can support and the maximum impact speed that they can reach.
The horizontal shock testing system
The horizontal impact simulation machine simulates the horizontal impacts that may affect the safety and stability of the load, which take place during the transportation or handling of the goods.
The shock machine uses a motor to propel the load against a cylinder, which can control the impact wave.
In this way, the impact wave simulation machine provides a more advanced solution: the cylinder, which is filled with nitrogen, allows for the adjustment of pressures in the impact area, which makes it possible to program the impact wave.
This shock testing system comes in two different models:
- Model SF-HIH1000 uses a hydraulic actuator and allows for the testing of loads of up to 1000kg (2,205 lb.), with an impact velocity of 4 m/s and an impact platform of 1500x2000x2000 mm².
- The remaining solutions (SF-HIE2000, SF-HIE1500 and SF-HIE100 ) use electric motors and allow for a maximum load of 2000kg (4,410 lb.) and an impact surface of 1400×1800 mm².
Why you should choose Safe Load TT’s shock testing equipment
Safe Load Testing Technologies’ shock testing machine offers two clear advantages: its design and its user-friendly operation.
On one hand, the external looks of the machine pays special attention to aesthetics. It has also been designed with international standards and protocols in mind.
On the other, the control software developed by Safe Load Testing Technologies has been designed with the user in mind, making the use of the machines a completely intuitive experience.
Still, even the most demanding and complex tests can be easily performed by any operator using a touchscreen and a simple program.
In addition, there is a wide range of incline shock testing systems and horizontal shock machines to choose from, to accommodate the needs of the company and the users.
Thanks to its modular design, the horizontal shock machine can be customized to be able to perform EUMOS stability tests.
