TEU Testing

To correctly test Twenty-Foot Equivalent Units (TEU) it requires coupled and uncoupled testing. At CCT, we have full capability to perform full testing on all sizes of TEU formations. To receive a CSC certification bicons, tricons, and quadcons must first pass all 1496-1 tests as a TEU. TEU testing or coupled testing is the most critical because in most cases this is how the containers will be shipped whether by truck, train, or ship. Nevertheless, if it is a singular bicon, tricon, and quadcons dummy containers are used to complete the core tests. Once the coupled core tests are completed the TEU is separated and one of the units is selected for singular testing. This singular testing or uncoupled testing consists of top lift, bottom lift, fork pocket lift (both directions), side wall/end wall (dependent), and weatherproofness. All the singular tests are crucial, but the singular lift tests are especially important because this is how the units will be transported when in the field and need to be able to support the weight inside. After all this testing is complete an equivalent unit can be certified for CSC approval. Depicted in the picture is top lift. The container is loaded with test load weight equivalent to 2R-T of the singular unit. Chains connect to all four top corner castings via hook and the chains connect to a ring attached to the Intermodal Test Center’s 30 Ton capacity crane. The container is lifted for five minutes and returned to the ground. No deformation should occur to deem that the unit is not transportable.
