Short answer
ASTM D5276 is the standard test method for dropping loaded containers by free fall: boxes, cylindrical containers, and bags and sacks. It describes how to drop a packed unit onto a hard surface and see how the package and its contents respond. It is a test method, not a pass/fail specification, and it does not set a drop height. A supplier or lab that quotes a D5276 result should also say which other document supplied the heights, orientations and acceptance criteria.
Definition and scope
The ASTM title is “Standard Test Method for Drop Test of Loaded Containers by Free Fall”. The current designation on the ASTM store is D5276-19, listed there as reapproved in 2023 (D5276-19R23, shown as active; the base D5276-19 record carries a “Historical” label). Anyone citing the standard in a quality document should name the exact revision they used. Source: ASTM store, checked 2026-11-01.
The scope covers procedures for the drop testing of loaded boxes, cylindrical containers, and bags and sacks by free fall. For containers not exceeding 110 lb (50 kg), ASTM states that the method fulfils ISO 2206:1987 and ISO 2248:1985. The method references related ASTM standards D880, D6055, D6179 and D4003, Practice D4169, and the two ISO documents above.
How the test is used in practice
Westpak, a commercial packaging test laboratory, describes D5276 as a way to evaluate how a package and its contents respond to free-fall impacts of the kind seen in distribution, for units that are handled manually. Drops are made onto corners, faces and edges of the package. The impact surface is a horizontal, flat, rigid surface (concrete, steel or stone) whose mass is at least 50 times that of the heaviest sample (Westpak, checked 2026-11-01).
The same source notes that D5276 does not specify the drop height. The height comes from an industry standard or from a custom test plan written for the product. That is why “tested to D5276” alone does not say how hard the package was dropped.
Related standards compared
D5276 is often named next to other documents that have a different job. The table gives each owner’s own description of its document.
| Document | What its owner says it is | Weight band stated |
|---|---|---|
| ASTM D5276 | Test method: drop test of loaded boxes, cylindrical containers, and bags and sacks by free fall (ASTM store) | 110 lb (50 kg) for the ISO equivalence statement |
| ASTM D4169-22 | Practice for performance testing of shipping containers and systems: a uniform basis of evaluating, in a laboratory, the ability of shipping units (ASTM store) | Not stated on the store page |
| ASTM D6179 and D880 | Named by Westpak as the related methods for large, bulk or unitized loads | Not stated in the source |
| ISTA 1A | Integrity testing for packaged-products weighing 150 lb (68 kg) or less (ISTA) | 150 lb (68 kg) or less |
| ISTA 2A | Partial simulation test, same weight band as 1A (ISTA) | 150 lb (68 kg) or less |
ISTA and ASTM D4169 are separate documents from D5276. For an ISTA parcel-shipping test, see ISTA 3A.
Where it matters for lab and medical supply shipping
For anyone reviewing how packaged laboratory or medical supplies are shipped, the practical value of D5276 is as one input to a documented packaging test. Because the method leaves drop height to another document, a test report is only as informative as the plan around it. A short checklist of what to ask a supplier or test lab:
- Which revision of D5276 was used (for example D5276-19 reapproved 2023)?
- Which other document or custom plan set the drop heights and the corner, edge and face sequence?
- Was the unit within the 110 lb (50 kg) range for which the ISO equivalence statement applies, or was a method for larger loads (D6179, D880) used instead?
- Was D5276 one step inside a broader practice such as ASTM D4169, or a stand-alone drop?
- What did the report treat as damage to the package and to the contents?
Packages that carry regulated contents have their own packaging rules. See hazmat shipping for medical supplies, biohazard bag and container requirements and FDA-cleared sharps containers. A drop test report does not replace those requirements.
Common misunderstandings
“D5276 sets the drop height”
It does not. The height is set by an industry standard or a custom plan.
“A D5276 report means the package passed a distribution standard”
A drop by itself is one hazard. Whether a package meets a distribution test depends on the practice or procedure that wraps it, such as ASTM D4169 or an ISTA procedure, and on its acceptance criteria.
“The standard is historical, so it is withdrawn”
The ASTM store shows a “Historical” label on the D5276-19 record, while the reapproved D5276-19R23 version is listed as active. Cite the revision you used and check the current listing.
FAQ
What is ASTM D5276?
The ASTM standard test method for dropping loaded boxes, cylindrical containers, and bags and sacks by free fall. Source: ASTM store, checked 2026-11-01.
Does D5276 specify a drop height?
No. According to Westpak, the height is set by an industry standard or a custom test plan.
What size of package is it for?
ASTM states it fulfils ISO 2206:1987 and ISO 2248:1985 for containers not exceeding 110 lb (50 kg). Westpak points to D6179 and D880 for large, bulk or unitized loads.
