What compression testing means?
During transport, handling and warehouse automatic storage, compressive forces are produced on the load due to the stacking of the packages or the exercise pressure between each other during movement. A compression tester allows to characterize the product & packaging systems and to simulate the stress that it suffers during the distribution cycle.
The main goal of a compression test is to determine the behavior or response of a material while it experiences a compressive load by measuring fundamental variables, such as strain, stress, and deformation.
Compression testing equipment procedure:
In a compression test, the package is placed between the two plates of the compression tester, that distribute the applied force that pushes inward from opposite sides.
Different testing modes:
- BCT(Box Compression Test) determination.
- Creep characterization.
- Apply and hold.
- Apply and release.
