1P End Wall Testing

Your eyes do not deceive you. The container doors are in fact bulging out beyond the ISO plain. The picture to the left is a picture of end wall testing. To be more specific it is 1P end wall testing. Normally, ISO and CSC certified containers need to pass end wall testing at forty percent of the payload. Which is far less pressure and less dangerous. In both cases, a calculated uniform load based on the payload of the container is distributed across the end surface to test structural integrity of the container walls. This test is instituted and especially needed when cargo is free moving inside the container during international travel to make sure that the container will not be damaged outside of its ISO measurement tolerances, as well as, not allow the cargo to spill out of the container causing harm to itself and whatever is outside of it. In this case, the picture depicts a 1P test being run on a specialized container modified in a matter to be able to support at least one hundred percent of the payload. The test was run from a safe distance and the container passed after it was able to bend without breaking or more importantly deflect to an extreme amount, but not open and go back to its original position.
