Low Temperature Testing

All matter behaves differently depending on the temperature. In manufacturing, products have to be tested to ensure that they can perform in real world temperatures. One of these tests is the low temperature testing. In this test, products are tested to determine how they behave when exposed to low temperatures.

Low temperature testing chambers are not very different from the air conditioners found in homes. The main differences are the scale of the components and the low temperature testing fluid used in the system.

Certain materials become brittle or change dimensions when cooled. A flexible rubber, for example, becomes rigid and contracts when placed inside a freezer. Another example are combustion engines. In the case of an engine with various mechanical parts that operate under immense pressures, the changes properties from low temperatures can lead to increased wear, premature failure of components, and impeded performance. This is why, with cars, it is important to let the engine warm up for one or two minutes before driving away.

Low temperature testing exposes problems while the products are still in the production process, instead of being in the hand of end-users. Just like all manufacturing tests, it makes sure problems are detected and solved before products leave the factory.
