ASTM D6055 Standard Test Methods for Mechanical Handling of Unitized Loads and Large Shipping Cases and Crates
The purpose of ASTM D6055 shipping container testing is to determine the integrity of unitized loads and large cases and crates. The standard assesses the ability of the contents to endure normal handling using standard mechanical handling equipment. This package testing standard is not intended for individual drums or palletized drums.
An ASTM-D-6055 test lab must be able to provide the testing using one of the following seven test methods:
Test Method A: Fork Truck Handling. This method is used for testing the ability of the shipping unit to withstand repeated handlings of a fork truck. In performing the fork truck handling test, use an actual lift truck with fork attachment to lift the shipping unit. The lift truck and blade(s) shall be capable of handling the size and quantity of products in accordance with current practice.
Test Method B: Spade Lift Test. Test method B is used or lifting by spade lift attachment to determine the ability of the handling flap of the case or shipping unit to withstand repeated lifting and handling. In performing the spade lift test, use an actual lift truck with spade lift attachment to lift the shipping unit under the lifting flap. The lift truck and blade(s) must be capable of handling the size and quantity of products in accordance with current practice.
Test Method C: Clamp Handling Test. This method is used for lifting by a hydraulic clamp attachment. This determines the ability of the shipping unit to withstand squeeze clamp handling consisting of repeated side compression and lifting. In performing the clamp handling test, use an actual lift truck with the appropriate load clamping device to lift the shipping unit. Provision shall be made to measure the clamp force between the platens using a load cell(s) or other suitable device.
Test Method D: Push-Pull Handling Test. The push-pull handling test determines the ability of a unitized load on a slip-sheet to withstand repeated handling by this test method. In performing the push-pull test, use an actual lift truck with the appropriate gripper jaw for pulling the load by the slip sheet tab onto the load plate. Alternatively, any suitable pulling device equipped with a gripper jaw may be used.
Test Method E: Grabhook Test. This test method uses grabhooks to determine the ability of the shipping unit to withstand the horizontal pressures of the grabhooks. In lifting the case or crate with grabhooks or slings, a hoist with grabhooks or slings attached is the simplest and easiest, but the test may be made with a tackle or by lifting the case or crate with jacks and setting it into grabhooks or slings supported by some form of truss.
Test Method F: Sling Tests. The method is used for lifting by wire rope, cable, or woven fiber slings to determine the ability of the shipping unit to withstand the compression of slings.
Additional Test Methods. Additional test methods that apply to mechanical handling and rough handling tests of unitized loads and large cases and crates can be used. These can include incline impact tests, described in Test Method D 880; horizontal impact tests, described in Test Method D 4003.
