Icing & Freezing Rain Testing

Guarantee the quality of your products

What is THE Icing & Freezing Rain testing and why is it important?

Icing testing reduces the risk of product failure in the field by assessing equipment's ability to withstand a build up of surface ice. The test is performed in a climatic chamber and replicates the formation of ice due to freezing rain, or from sea spray and splash.

Failures seen from this type of testing are varied, ranging from the binding of moving parts, structural damage, through to loss of visibility through windshields and optical devices.

Why choose TÜV SÜD for Icing & Freezing Rain testing?

TÜV SÜD engineers carefully build up ice by spraying water conditioned to just above freezing point over the equipment which is stable at a temperature below freezing. The water freezes upon impact on the equipment forming a layer of ice. Test specifications typically ask for 3 to 75 mm of ice build up.

We can provide manufacturers with the following testing services:

  • Testing for large test items down to small hand held items
  • Quick build to the desired depth of ice by experienced engineers 
  • Customer access within the chamber for inspection and functional checks

We provide testing for icing and freezing rain to many specifications including the following common standards:

  • MIL-STD-810
  • DEF-STAN 00-35
  • EN 62271-102


  • 11 temperature chambers
  • Temperatures between -65°C and +190°C
  • Largest chamber 6 x 5 x 4 meters
  • 3 rapid temperature change chambers greater than 5˚ / minute
