Standardized climatic tests: Heat and cold. Constant and changing

No one can choose the weather, but definitely the best packaging for products!

Climatic testing is used to simulate climatic conditions during transport and at the destination of packages, load units and equipment. How much moisture can the corrugated board withstand? What temperature fluctuations can the test samples be exposed to? Does the equipment work properly in high heat? How much is too much? Of course, the same goes in the opposite direction: does the machine work well in cold and sub-zero temperatures? How little is too little?

But this does not answer all our questions, because: What happens to the products under changing climatic conditions? For example: When products are exposed to particularly low temperatures and then become damp. As a result, ice formation or condensation can damage the products. If they are exposed to particularly high heat, the plastic could melt or the product could spoil.

Unique in northern Germany: A 24 m² climate chamber

The climatic tests are carried out in our walk-in climatic chambers. Or, optionally, in our climatic chambers. We can also test the function of air-conditioning systems. We provide electrical connections, compressed air or network connection for this purpose.

The test procedures differ significantly: on the one hand we can work with constant climate, on the other hand there are test options with alternating climate conditions. If the sample is exposed to a constant climate, this usually means that the climate penetrates into every area of the test sample. A frequent specification in test procedures is therefore an exposure time of 72 hours.

Climate change tests, on the other hand, have a different focus. Here, the aim is to simulate shipping conditions. These tests, called temperature studies, are of particular interest to customers who are active in the medical field and want to qualify their packaging systems. For example, manufacturers of medical packaging or vaccines.

When we simulate a shipping process, we do so with the help of strategically placed sensors called temperature and climate sensors. These check whether all sensors have the same temperature after the test. If this is the case: Great, that tells us that the selected packaging is suitable, for example, for shipping medications at a specified temperature.

Change of temperature from 10°C to 50°C in only eight minutes

When we use our climate chambers, we can adjust the temperature as desired. Just as if you were walking with your package from the Arctic to the desert. Down to a minimum temperature of -70 degrees Celsius and at a rate of change of 4.8 Kelvin per minute. That sounds fast and productive. And it is, because it enables us to implement your testing needs quickly and accurately.
