During transport and storage, packaging is exposed to varying climatic conditions. For some products, such as high-tech components, medical equipment or defence equipment, exposure to extreme cold or heat can have a major impact on performance and safety. A temperature test simulates these low and high temperature conditions.
At Faes, we understand that such a test is more than just a formality. Through our renowned partners, we carry out temperature tests that closely match your specific application and relevant standards. This gives you not only a test result, but also insight into how your packaging performs in practice and where optimisations are possible to minimise risks.
A temperature test is a simulation in which packaging is exposed to both low and high temperatures for a predetermined period of time. This can range from extremely cold (down to −40 °C or lower) to very hot (+70 °C, +80 °C or even +180 °C depending on the test protocol). The aim is to check whether the construction, materials and closures of the packaging can withstand the physical and functional challenges posed by temperature fluctuations. Depending on the method chosen, the temperature can be maintained at a constant level, cycled or combined with humidity to simulate realistic transport and storage conditions.
Both cold and heat can affect materials: at low temperatures, plastics and coatings become brittle, adhesive bonds can come loose and seals can harden. At high temperatures, plastics and metals deform, while adhesives and coatings can become liquid. This can result in the packaging providing less protection against shocks, moisture or contamination. By testing in advance, you can determine whether your product or packaging can withstand extreme conditions.
Temperature testing is primarily intended to determine whether packaging, such as a crate or case, retains its protective function under extreme conditions. This demonstrates that the construction and materials perform well in practice. In addition, temperature tests play an important role in certification and compliance with international standards, such as IEC 60068, ISO 16750, ISTA, ASTM and military standards (including MIL-STD-810H). In some cases, such as with lithium batteries, specific test protocols are even mandatory.
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.
At Faes, we guide the process from start to finish, so you can be sure of packaging that not only passes the test, but also performs optimally in practice. Our approach consists of four key steps.
Requirements determine
Together with the customer, we identify all relevant product and transport characteristics, as well as applicable standards. Consider dimensions, weight, fragility, transport modalities and any sector- or customer-specific guidelines. This analysis forms the basis for the packaging design and testing requirements.
Design and optimization
Our engineers translate the specifications into packaging that meets all requirements. This includes the choice of materials, the construction of the case or crate, and the interior design that protects the contents. Any improvements from previous test results are incorporated immediately.
Coordinate the test
Faes works with reputable partners to carry out the test professionally and according to proper standards. We take care of the logistical coordination, deliver the packaging to the testing authority and ensure that all documentation is available and correct.
Evaluation and improvement
After completion, we analyze the test results and discuss them with the customer. If necessary, we make improvements in the design or choice of materials so that the packaging performs optimally in practice.
This structured approach enables us to deliver packaging solutions that comply with international standards and are perfectly tailored to your logistical and operational reality.
A temperature test is a reliable way to assess whether packaging and its materials can withstand extreme cold and heat. This shows whether the construction, closures and interior retain their protective function under varying temperature conditions during transport and storage.
At Faes, we combine in-depth knowledge of packaging design and production processes with testing capabilities. This allows us to demonstrate that packaging meets the specified requirements and guarantee quality at every step: from design to implementation.
