In order to determine the strength of a packaging, a so-called Box Compression Test (BCT) is conducted. Prior to the test, the packaging is conditioned on the necessary temperature and humidity so the starting conditions are always equal. If necessary, this allows for a comparison of the test results to previous tests.
The test is always conducted five times in order to exclude any coincidental occurrences. This test is performed in accordance with the ASTM test standard D642-00.
