ASTM D6344 Transport Packaging Concentrated Impact

Completely filled transport packaging, susceptible to damage by concentrated low level impacts, are tested as per ASTM D6344. Specimen packages are tested on pass or fail basis by dropping or swinging a solid cylinder onto identified points as per free-fall or pendulum scenarios.

Scope:

The standard ASTM D6344 describes the apparatus and procedures used to test the robustness of completely filled packaging against low level impacts. Transport packaging is subjected to various impact loads during transportation that place the contents at risk. Packaging for transport involves optimum material selection and package design, to meet cost and strength requirements. The ASTM D6344 test simulates realistic low level impact scenarios on samples of the filled transport packaging and is useful in evaluating various material and design options. This test is appropriate for lighter grade corrugated/fluted cardboard boxes or stretch-film wrapped packaging.The standard ASTM D6344 describes the apparatus and procedures used to test the robustness of completely filled packaging against low level impacts.

Test Procedure:

Realistic test specimens of packages filled with actual contents are subjected to dropped object and pendulum impacts in accordance with ASTM D6344. The desired impact spots on the surfaces and the pass or fail criteria are decided prior to commencement. If the package requires conditioning (e.g cold storage or controlled humidity), it is preferable to conduct the tests in the conditioned atmosphere.

The test apparatus comprises a solid steel rod with a rounded end that is used to impact the package at identified points, with support and guiding arrangements. Free-fall impacts of the steel rod can be guided (through a cylindrical tube) or non-guided, from various heights and energy levels. The specimen is deemed passed or failed based on agreed acceptance criteria. It is possible to conduct this type of testing using modified procedures that provide a numerical response.

The number of test specimens can be decided by statistical methods in case large quantities are involved.

Specimen size:

Large as well as small packages can be subjected to this test, subjected to handling limitations at the test facility.

Result:

The retardation is reported in nanometres (nm) and the stress values in Megapascals (MPa). Visual patterns of stress The tested specimen is deemed pass or fail based on acceptance criteria established prior to commencing the test.
