A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Not all of the test methods are applicable to all products, containers, and loads. These test methods are applicable to common means of material handling as follows: Normally, Test Methods A and B are not applied to unitized loads.
The SI units given in parentheses are for information only. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Additional tests that apply to mechanical handling of unitized loads and large cases and crates include incline impact tests, described in Test Method D and horizontal impact tests, described in Test Methods D and Test Method D Test Methods D includes a special pallet marshaling test and Test Methods D provides test methods for pallets and related structures.
Current edition approved Sept. A case or crate of this type may weigh from lb 45 kg up to many tons and measure xstm. The case or crate may be secured to or carried by a base or pallet. Frame members may be provided for rigidity throughout the container. Where this test is performed to satisfy a regulatory or contractual requirement, its use is subject to approval by the agency concerned.
Apply sufficient force to lift test item to prescribed height, then release test itemor 5. Perform the test upon a? Test Specimen and Number of Tests 6. If it is not possible to test an entire unitized load, then sufficient articles or containers should be assembled such that the height and one base dimension are nearly the same as the proposed unitized load.
The same test item may often be used for all applicable tests if not tested to failure. Load the test item with the actual contents for which it was designed.
If use of actual contents is not practical, a dummy load of the same total mass, size, and weight distribution may be substituted. The contents or dummy load shall be blocked, braced, and cushioned in place and the package closed normally as for shipment. Raise the other end of the test item successively to prescribed heights and release to fall freely on the impact surface. Where test items are tall or top heavy, provision must be made to prevent the test item from tipping over after the drop is made.
The drop test impact surface is speci? See Annex A1 for alternative drop test procedures. Place a 4 to 10 in. Raise the unsupported end of the test item so that the lower corner of that end reaches a speci? Position load while in the air for?
Release the test item and allow to fall freely. NOTE 3—When conducting a drop test using slings on a corrugated? This board will prevent each sling from collapsing the top of the corrugated?

In addition to these measures, a record should be made of any changes or breakage in the test item and their location. A recommended sample form for recording the measurements and notations made during the drop tests is shown in Fig.
Loose chains, slings, or other similar restraints may be positioned around the test item to prevent a complete tipover and impact that could result in personal injury. Such restraints should not be used as an alternative to conducting the test in an area large enough to ensure operator safety. Tipover Test Procedure In the case of tall test items, the repeat tests shall be carried out with the test item standing on its normal base and toppling onto each side face in turn see Fig.
In the case of?
For the designation of the faces referred to in the tables, see Test Method D If use of actual 4 contents is not practical, a dummy load of the same total mass, size, and weight distribution may be asm.
The contents, or dummy load shall be blocked, braced, and cushioned in place and the package closed normally as for shipment.
Then allow it to overbalance without thrust so as to impact on Surface 4. If simulated or dummy contents were used, full details shall be given.
