Full and Packed Shipping Packages: Unit Load Stability Test
Shipping packages, essential components of the logistics chain, are subjected to various environmental and mechanical stresses during storage, handling, and transportation. To ensure their performance and structural integrity, it is essential to conduct stability tests on unit loads. These tests simulate real-world conditions that packaging is exposed to, focusing on aspects such as pallet handling and push/pull operations.
Evaluating the performance of ready-to-ship unit loads is crucial to ensuring the safety of packaged products, minimizing transport damage, and optimizing packaging lifespan. Unit loads can undergo a variety of tests to assess their strength and stability, including compression, vibration, drop, stacking, and environmental tests.
Pallet handling is a common practice in shipping logistics and can exert significant stress on packaging. Pallet handling tests aim to replicate these conditions, evaluating how unit loads behave when lifted, moved, and placed using standard pallet handling equipment. These tests can help identify weaknesses in packaging design and inform necessary improvements.
Push/pull operations are also common in handling shipping packages. Unit loads are often pushed or pulled by hand or with the assistance of handling equipment. These actions can create forces and pressures that are not present during standard pallet handling. Push/pull handling tests help determine the packaging's ability to withstand these additional stresses without suffering structural damage.
Forklift handling is another important aspect of unit load stability testing. Annex A provides detailed procedures for these tests. Unit loads are often manipulated using forklifts during transportation and storage, and these machines can impose significant stresses on packaging. Forklift handling tests can help evaluate the packaging's resistance to lifting, moving, and placing forces.
Maritime transport is not covered in this standard.
