英文4857.4

Test Materials: GB/T 4857.4 outlines the use of transport packages, typically cartons or other packaging materials, to assess their compression strength and stacking performance. These materials should represent the packaging typically used during transport and must be prepared as they would be in real-world conditions, including appropriate sealing and filling.
Test Process: The test involves applying a controlled compressive force using a compression tester until the packaging material shows signs of failure, such as deformation or collapse. The load is applied progressively in a uniform manner according to the package’s size and type. The test is conducted under specific environmental conditions such as temperature and humidity, as stipulated by the standard.
Test Result Interpretation: Test results are evaluated based on the ability of the packaging to withstand the applied compressive force without collapsing or undergoing significant deformation. The maximum load a package can endure before failure indicates its stacking strength. This result helps determine the durability and performance of packaging materials under realistic transport conditions.
