Climate test in the laboratory

Climate tests include a large number of climatic change tests for products, technical equipment and materials. Climatic tests are among the environmental tests and are precisely regulated in the test standards DIN EN 60068-2 and DIN EN 60068-3.
Climate chambers or climatic cabinets are used as laboratories. The temperatures and humidity levels generated within them simulate real climatic loads but also extremes as well. For example, we can simulate global transport routes or ageing in the laboratory. It is also necessary to determine how technical equipment or individual components behave when they are exposed to continuous or sudden extremes of cold and heat or dry and humid heat.

 

Cyclic temperature changes and temperature shock tests also help to package products correctly. Climate tests in the laboratory demonstrate the serviceability and resistance of individual packaging materials and packaging. The knowledge gained in this way is equally important for product developers, manufacturers, shippers and users.

Changeable trend: We simulate all climates

A problem during transport: condensation in the container
Condensation in container

Modern consumer goods have often covered thousands of kilometres and passed through various climatic zones on their journey from producer to shop.
At the BFSV Institut of Packaging in Hamburg, we simulate these routes because our climatic test equipment generates cold and heat from -50 °C to +80 °C and we achieve relative humidity levels of 10% to 98%. Constant temperature tests and cyclically changing climatic tests show up weaknesses and material defects.

Why not use the BFSV climatic laboratories before your product goes into mass production?

Climatic loads are not only caused by external factors. During transport, closed containers protect against rain, saltwater and sun but things are happening inside: the ambient temperature rises and falls over the course of the day; moisture evaporates from the cargo. This gives rise to condensation which leads to mould or corrosion.

We simulate the climate on land, at sea and in the air. We can position, stack and test entire load units in our 24 m2 climatic chambers. Depending on the environmental simulation, we additionally subject the test specimens to mechanical loads and negative pressure.

Temperature tests accelerate ageing

If primary packaging is subjected to a climatic test, it is possible to determine the material’s lifetime. With controlled temperature increases in the climatic cabinet, the natural ageing process is greatly accelerated and it becomes possible to calculate the service life and expiry date. Without artificial ageing in the laboratory, the data would have to be generated in real time, which can take years. Temperature tests of this type are particularly relevant for medical packaging.
Accelerated ageing according to ASTM F-1980 allows statements to be made about the stability of the material over time. Pharmaceutical manufacturers then know when the sterile barrier system will deteriorate or may fail completely.
Using the various climatic tests permits targeted optimisation of packaging and ensures safe packing of products. Our test equipment and its specifications provide further information about this.
