What is the IBC Stacking Test?
Companies perform regular testing of their Intermediate Bulk Containers (IBCs) to guarantee the safety and longevity of their tanks. One such test, the stacking test, involves filling the container to a certain percentage of capacity, stacking it on another filled to the same capacity, and leaving it for a certain amount of time.
Why is the Stacking Test Used?
The stacking test ensures that each IBC tank lives up to its claims of sturdiness and stackability. A tank that collapsed in travel or storage would be a liability to the company that rented or sold it and could risk the lives of those moving it, as the tanks often weigh as much as 1100 kg when full.
What are the Specifics of the Stacking Test?
To pass the stacking test, an IBC must be loaded to at least 95% capacity and set on a flat surface. A second similar weighted unit or weighted plate is set on top. The unit must be left for a set amount of time, ranging from five minutes in some models to over 24 hours in others.
Who Performs the Stacking Test on IBCs?
Every company that sells or rents IBCs must perform this test on their units at regular intervals. These tests may be administered inhouse or by a testing company so long as certain details are recorded, including the name of the facility and administrator as well as general results and notes from each test.
