Humidity testing

Guarantee the quality of your products

What is THE Humidity testing and why is it important?

Humidity testing reduces the risk of product failure in the field by simulating the humidity conditions that products are exposed to during their lifetime. The test specification defines the applied humidity and test conditions, this may be a condensing test, where temperature and humidity cycle is performed precipitating condensation onto the sample, or a non condensing test where humidity is present in the air but does not cause condensation to form.

Why choose TÜV SÜD for humidity testing?

TÜV SÜD has the capability to test at humidity levels between 5% rh and 98% rh at various temperatures. Testing is performed in climatic chambers ranging in size from a small desk top chamber up to a 120 m³ drive-In chamber.

The laminar airflow within the climatic chambers ensures that a uniform humidity distribution is achieved throughout the entire volume of the chamber.

We can provide manufacturers with the following testing services:

  • Condensing and non-condensing humidity testing
  • Combined humidity and temperature testing
  • Combined humidity and altitude testing
  • Combined humidity, temperature and altitude testing

We provide testing for temperature to many specifications including the following common standards:

  •  IEC 60068
  • IEC 60529
  • RTCA/DO-160
  • MIL-STD-810
  • DEF-STAN 00-35

Any test not on our UKAS scope which is within our capability can be added quickly through our flexible schedule, which is a rare privilege granted to us by our accrediting authority


  • 11 humidity chambers
  • Humidity from 5% rh to saturation at +5°C to +85°C
  • Largest chamber 6 x 5 x 4 meters
