Will your package and product withstand the rigorous
conditions that it will face during transportation and
will it work properly in various climates? Our chambers can simulate a wide variety of conditions.
Conditioning, testing atmosphere:
Environmental chamber to simulate temperatures
and humidity encountered by packages.
The environmental conditions of testing are critical.
The measured performance of many packages is
affected by the conditioning and testing atmospheres.
For example, paper based products are strongly affected by their moisture content: Relative humidity needs to be controlled. Plastic products are often strongly affected by temperature.
Conditions of 23°C (73.4°F) and 50% relative humidity are common but other standard testing conditions are also published in material and package test standards. Engineering tolerances for the conditions are also specified. Often the package is conditioned to the specified environment and tested under those conditions. This can be in a conditioned room or in a chamber enclosing the test. With some testing, the package is conditioned to a specified environment, then is removed to ambient conditions and quickly tested. The test report needs to state the actual conditions used.
Engineers have found it important to know the effects of the full range of expected conditions on package performance. This can be through investigating published technical literature, obtaining supplier documentation, or by conducting controlled tests at diverse conditions.

Conditioning Containers, Packages, or
Packaging Components for Testing
