How is a temperature test conducted?
A temperature test follows a structured test protocol designed to simulate realistic conditions as accurately as possible. At our reputable partners, this is done in special climate chambers in which both temperature and humidity can be set and controlled with great precision.
Step 1 – Analysis and test plan
In step 1, an analysis is made of the application, the product and the transport and storage conditions. Where possible, a suitable test protocol is selected (e.g. ISTA, ASTM, ISO or MIL-STD methods). For certain product groups, the test plan is already determined by mandatory standards, as mentioned earlier.
Step 2 – Preparation of the packaging
The packaging to be tested is assembled in the same way as it is used in practice. At Faes, we often test with a dummy: an object that matches the customer’s product in terms of shape and weight. This ensures that the test results are representative of the actual situation.
Step 3 – Placement in the climate chamber
The packaging is placed in a climate chamber, after which the temperature is raised or lowered in a controlled manner according to the test protocol. Depending on the test, the temperature range for packaging is usually between -40°C and +80°C, with possibilities up to +180°C. In addition, there are chambers available that can cool to -70°C and chambers with the ability to subject the product to rapid temperature changes (thermal shocks).
Step 4 – Test execution
Depending on the protocol, the test may consist of a constant low or high temperature, cycles in which the temperature alternates between cold and warm, or a combination with humidity and mechanical stresses such as vibrations or shocks. This simulates how packaging behaves under prolonged exposure and sudden climate fluctuations.
Step 5 – Evaluation and reporting
Afterwards, the packaging is checked for damage, loss of function or defects in construction and sealing. The results are recorded in a test report, which provides insight into the performance and any areas for improvement in the design.
