The operating environment for your product will be subject to temperature swings, humidity changes and mechanical knocks and shakes. We can help you characterise your product for the intended operating conditions.

Environmental Testing

  • Temperature cycling – the repeated thermal expansion and contraction accompanying a temperature cycle can accelerate and exacerbate latent failure modes within the equipment under test.
  • High humidity & high temperature – this test will accelerate corrosion caused by atmospheric moisture.
  • Test to failure – useful data can be gained by gradually increasing the temperature outside the specified operating temperature range of the product to see what component or system fails. This is a good way of identifying potential weak spots in the design.

We have two environmental test chambers and can provide temperature monitoring of your equipment during the process

Chamber 1:

  • Temperature control from -60 to +180°C
  • Humidity control from 5% to 95%
  • Programmable temperature and humidity cycling
  • 115 litre capacity, internal dimensions 600 x 480 x 400mm, 60kg load

Chamber 2:

  • Temperature control from -40 to +125°C
  • Programmable temperature cycling
  • 250 litre capacity

Vibration Testing

Your product will be subjected to mechanical shocks and vibration during its life. This could occur during the shipping and handling process before it reaches your customer. Or, once unpackaged and in service, it could end up being installed or used anywhere. Equipment destined for industrial or automotive locations will be particularly susceptible to vibration.

When is the best time in the product development cycle to perform vibration testing? As soon as the prototype mechanical parts are available is preferred as it gives you time to fix any issues found during the testing.

Our vibration test system allows us to test your product to likely transport, operation and storage scenarios. We can apply different types of vibration tests to your product

  • Sinusoidal – a swept frequency sinusoidal displacement lets us find the resonant frequencies within the equipment under test and will highlight areas of improvement in the mechanical design. We have seen hard disk drives or batteries break free from their mounts with a surprising amount of damage resulting.
  • Random – most real world vibrations will be of a random nature such as those incurred during shipping.
  • Shock – a sudden application of force with a wide range of frequency components

The LDS V724 electro-dynamic vibration generator we use has the following capabilities

  • Sinusoidal max acceleration = 94g, max force = 6.7kN
  • Random max acceleration = 50g, max force = 5.3kN
  • Displacement max = 25mm pk-pk
  • Maximum velocity = 1.78m/s
  • Operating frequency = 1 to 4000 Hz
