ISO 2234 Stacking Test 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 ISO 2234 package sustainability load testing. Meeting the ISO 2234 stacking requirements can be difficult. Keystone understands the challenges and guides companies through the process.
Keystone Compliance creates an accurate test plan to eliminate expensive over-testing. Keystone also takes a consultative approach throughout the entire test program. We provide comprehensive reports shortly after completion of the testing. Finally, we provide the peace of mind that all of your needs will be met.

Summary of ISO 2234 Filled Transport Package and Unit Load Information
The international standard specifies three regulatory compliance methods. These package integrity test protocols carry out a stacking test on a complete, filled transport package or unit load. Whichever ISO 2234 method is used, the ISO transit compliance 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.
The ISO 2234 standard test procedure performs testing either as a single test or as part of a sequence of tests. The single ISO 2234 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.
After the completion of the ISO 2234 transportation standard, a custom report is written and includes the following information:
- A description of contents, if simulated or substituted contents were used, full details must be given;
- The relative humidity, temperature and the time of conditioning;
- The altitudes in which the test item was tested;
- The design and dimensions of any profile used;
- The type of apparatus used;
- Any deviations from the test methods described below;
- A record of the results, including observations which assist in the correct interpretation of the results.
Scope of ISO 2234 Complete, Filled Transport Packages and Unit Loads
The packaged 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 ISO regulatory compliance package test is to be carried out in atmospheric conditions identical to those used for conditioning. In other circumstances, the ISO 2234 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 method 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.
Significance of ISO 2234 Static Load Testing
The package integrity test is used to investigate 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 which rests on a container.
Expert ISO 2234 Stacking Tests Using a Static Load Package Testing
We can accommodate flexible and rigid packages of all sizes, including large pallets. In addition to ISO static load testing, Keystone Compliance has a full scope of expertise including drop, leak penetration, and accelerated aging. Lastly, we have a full lab of test equipment which permits us to provide short lead times on scheduling.
