GB/T 4857.3

Test Materials: The test materials specified in GB/T 4857.3 are transport packages and unit cargoes, typically consisting of items like cartons, boxes, or containers filled with goods. These materials must be in a condition representative of their typical use in transportation, including the packaging and contents.
Test Process: The static load stacking test involves placing a package or unit cargo on a flat surface and applying a specified load for a given duration. The load is applied evenly across the top of the package to simulate conditions during transportation and storage. The test conditions, including load weight and duration, are defined according to the package’s intended use.
Test Result Interpretation: Test results are interpreted based on whether the package or unit cargo maintains its structural integrity under the applied load. If deformation, leakage, or breakage occurs, the package fails the test. The acceptable load-bearing capacity of the package is determined by the absence of significant damage during the test period.
