ISO 2234 Stacking Tests Using a Static Load
ISO 2234 assesses the strength of a package or unit load when subjected to stacking. As an ISTA and ISO 17025 certified lab, we realize the importance of international safe transit testing. Meeting the ISO 2234 package integrity requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone’s package testing labs quickly create an accurate test plan to eliminate expensive over-testing. When packages do not meet the requirements, we assist with finding solutions. Keystone Package Testing partners with customers to achieve package compliance.

Summary of ISO 2234 Filled Transport Package and Unit Load
The international standard specifies three methods. These test protocols carry out a stacking test on a complete, filled transport package or unit load. Whichever method is used, the test method assesses the performance of a package, in terms of its strength or the protection it offers to its contents when it is subjected to stacking.
This ISO 2234 test procedure may be performed either as a single test or as part of a sequence of tests. The single test investigates the effects of stacking. The sequence of tests measures the ability of a package or unit load to withstand a distribution system that includes a stacking hazard.
ISO 2234 Stacking Testing Procedures
The test item is conditioned in accordance to ISO 2233.
The test item is placed on a flat, horizontal surface and subjected to an evenly distributed load applied from above. The load, atmospheric conditions, period of time under load, and attitude of the test item are predetermined.
Wherever possible, the test is to be carried out in atmospheric conditions identical to those used for conditioning. In other circumstances, the test shall be carried out in atmospheric conditions which approximate those used for conditioning, as closely as practicable.
Method 1 – Stack of test items, each item being identical with the item under test. The number of test items is such that their total mass forms an appropriate load.
Method 2 – Loading platform, free to tilt to an equilibrium position on the test item, together with an appropriate load.
Method 3 – Loading platform, such that the lower surface is constrained to remain horizontal, together with an appropriate load.
If methods 2 and 3 are being used, the masses are placed making up the load on a platform without impact. This ensures that they are in full contact with the loading platform being released. The load is applied for a required period of time or until collapse.
Lastly, the load is removed and the test item is examined.
At the conclusion of the test, a report is written encompassing the following information:
- A reference to the ISO 2234 standard
- Unique identification of the report
- Date of testing
- Name of test engineer
- A description of the contents
- Relative humidity, temperature, and the time of conditioning
- Any deviations from the test method
- A record of the results
Significance of ISO 2234 Static Load Package Testing
The test is used to investigate the performance of handling equipment under particular conditions of loading. For example, when the bottom package in a stack rests on an open-decked pallet load. Another example includes when the profile of the superimposed load is eccentric, as when it is supported on the bearers of a single decked pallet that rests on a container.
One of the primary objectives of stacking testing is to assess the structural integrity of packages during transportation and storage. Stacking places significant pressure on the lower packages within a stack, which can lead to damage, deformation, or failure if the packaging design is inadequate. ISO 2234 stacking testing ensures that packages can withstand the intended loads, reducing the risk of product damage, contamination, and potential safety hazards.
Additionally, products can be sensitive to environmental conditions, such as pressure, vibration, and impact. Stacking testing helps evaluate package design and material strength to minimize the risk of product damage during handling, loading, and unloading. By subjecting packages to controlled stacking tests, manufacturers can identify weak points and make design improvements that protect the integrity and quality of the products throughout the supply chain.
Lastly, ISO 2234 stacking testing plays a crucial role in protecting product quality, enhancing customer satisfaction, and reducing costs for businesses across various industries.
