Ansti Life Support System Test Facility (LSTF)

The Life Support System Test Facility (LSTF) is a fully integrated laboratory system offering the capability to conduct tests at the surface and immersed in temperature controlled water to a maximum depth of up to 500msw (or deeper upon request).


Enables precise testing to extreme conditions so design engineers can ensure the effectiveness of critical equipment.

  • Diving depth control with water chilling and heating
  • Breathing air heated & humidified with adjustable breaths per minute and tidal volume
  • Valve cracking effort, exhale resistance and work of breathing
  • Fast response gas analysis with CO2 injection and O2 dilution simulating respiration
  • Hydrostatic imbalance testing of rebreathers
  • Cold water chiller 
  • Breathing air heated & humidified
  • Buoyancy Control Device Testing



  • Suitable for CE marking performance tests of defence, commercial and recreational SCUBA equipment

  • Verify whether equipment meets or exceeds dynamic breathing performance requirements

  • Define the limits of product performance under diverse operating conditions

  • Reduce costs of product testing with real time results achieved accurately and efficiently every time

  • View the performance of breathing apparatus under test with real time data acquisition and display

  • Large test vessel diameters up to 1000mm and internal variable orientation accommodate twin cylinder SCUBA equipment, rebreathers, diving masks, helmets, bandmasks or other equipment

  • Intuitive console controls, clear computerised virtual instruments and printable test certificates
