Compression Test on Plastic Beakers, Buckets, Boxes, Containers, Barrels and Similar Dimensionally Stable Packagings

Compression tests have different purposes. Examples:

• Determination of stacking characteristics: There are various methods for this type of test according to Standard and material. Individual or several packages are loaded until failure. This will indicate the maximum stacking height which can be used. For plastic joghurt pots, this test is also made with completely filled trays. Or a certain load may be applied for a pre-set length of time or until failure.
• Determination of inherent rigidity: This test gives information for the process of packaging: The packaging has a certain load applied when it is closed (when the lid is put on), and it must withstand this closing process without problem.
• Fatigue tests: A hysteresis test is performed on a pail to see how often a certain load can be applied before it breaks. In practice this happens when palettes are loaded and unloaded. Not every loading and unloading cycle is shown. Only the 1st, 100th, 500th and 1000th cycles are displayed for monitoring.
