ISO 12048 defines compression and stacking tests for complete, filled transport packages using a compression tester. It is commonly used to evaluate how a packed shipping case or carton will resist top-load forces during warehousing, pallet stacking, and distribution.
If you are not sure whether your package type, loading targets, or pass/fail criteria align with ISO 12048 versus other package performance standards, talk with our team about your application before specifying equipment or test conditions.
ISO 12048:1994 — Packaging — Complete, filled transport packages — Compression and stacking tests using a compression tester
ISO 12048 is an International Standard for evaluating the compression resistance of complete, filled transport packages and for running a stacking test using the same type of compression-test apparatus.
In practice, this standard is used when you need a controlled, repeatable way to apply compressive loading to a packed shipper (for example, a corrugated box or similar transport package) to understand deformation behavior and/or failure under load.

Quick Definition
ISO 12048 describes how to run controlled compression and stacking evaluations on a complete, filled transport package using a compression testing machine (compression tester) with platens, to simulate top-load forces encountered in storage and distribution.
What This Standard Covers
ISO 12048 focuses on two closely related test approaches performed on a filled package using a compression tester.
- Compression resistance test: A controlled compressive load is applied to the package to evaluate its resistance to compression.
- Stacking test: A specified compressive force is maintained for an agreed period of time (or until failure) to simulate sustained stacking conditions.
Because the test item is the complete, filled package, results reflect the combined behavior of the outer container, closures, internal packaging, and contents interaction under top-load.
Why This Standard Matters in Testing
Compression and stacking performance are common limiting factors for shipping cases and palletized loads. ISO 12048 supports decisions such as choosing a package design, setting a maximum stacking height, qualifying changes to materials or closures, and checking whether a packed product can tolerate expected warehouse and transit loads.
For QA/QC and procurement, this test approach is often used to set acceptance criteria tied to real distribution risks (excessive deformation, loss of seal integrity, or collapse) rather than relying only on material-level properties.
Common Materials, Product Types, or Applications Covered
ISO 12048 is applied to “transport packages” as shipped, across a wide range of industries. Typical examples include:
- Corrugated shipping boxes (filled with product and internal packaging)
- Folding cartons or paperboard cases used as transport packaging
- Retail-ready shippers or multi-packs intended to be stacked during distribution
- Cases used in pallet stacking where top-load is a dominant hazard
Because the method is package-level, it can also be useful for comparing alternative pack-outs (different inserts, void fill, partitions, or product orientation) when the outer box remains the same.
Common Test or Verification Workflow
ISO 12048 is typically used within a package qualification or design validation workflow where the test lab and the spec owner agree on the load targets and the pass/fail criteria for the specific shipment scenario.
Common workflows: Screening packaging designs, comparing suppliers, validating packaging changes, setting stacking limits, and supporting distribution test schedules that include compression/stacking as one element.
What to define up front: Package orientation, loading target (to a limit or to failure), duration for sustained stacking, and what constitutes unacceptable deformation or failure for the product and pack-out.
Equipment Commonly Used for This Standard
ISO 12048 calls for a compression tester suitable for applying compressive loading to complete, filled transport packages in a controlled way.
Common equipment: Package compression testers or universal testing machines configured for compression with appropriately sized compression platens.
- Compression platens: Flat platens sized to cover the package footprint; platen alignment and stiffness matter for repeatability.
- Load measurement and control: A load cell and control system capable of reaching the required force range for the package type and maintaining an agreed load for stacking evaluations.
- Fixture and clearance considerations: Sufficient daylight/opening for the tallest packages, and a stable frame for larger shipping cases.
- Data capture: Force and displacement (and, when needed, time under load for stacking) to support reporting and acceptance criteria.
If you are comparing force capacity, platen size, or test space for larger shippers or pallet-pattern cases, you can request pricing for a compression-testing setup matched to your package dimensions and target loads.
How to Read This Designation or Revision
ISO 12048:1994 identifies the standard number (12048) and the publication year (1994). In many specifications and test reports, the year is included to avoid ambiguity about the referenced edition.
ISO also indicates that this edition has been reviewed and confirmed (most recently noted in 2022). When quoting or reporting results, it is good practice to cite the complete designation as written in the purchase specification or test plan.
Revision sensitivity: Equipment setup is generally stable (compression tester with platens), but details such as conditioning, procedure options, and reporting expectations can vary by the exact cited edition and by the test plan agreed between parties.
Related Standards, Methods, or Frameworks
Compression and stacking performance may be referenced alongside broader packaging test planning or alternative stacking approaches, depending on how a company builds its distribution qualification.
- ISO 2234 addresses stacking tests using a static load (often used when sustained stacking is evaluated without a compression tester approach).
- Legacy references: Older ISO compression-test documents in this area have been withdrawn and replaced by newer publications.
When a customer specification cites multiple package tests (for example, vibration, drop, and compression/stacking), confirm which document governs each portion of the sequence and what order/conditioning is expected.
