ISO 12048 Compression Testing

ISO 12048 Compression and Stacking Package Testing

ISO 12048 specifies the resistance to compression of a transportation package. As an ISTA and ISO 17025 certified lab, we realize the importance of ISO 12048 compression package testing. Meeting the resistance requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone provides the peace of mind that all of your needs will be met. When packages do not meet the requirements, we assist with finding solutions. We are in constant communication throughout the test process. Lastly, Keystone takes pride in having a reputation for helping customers achieve their ISO 12048 package testing certifications.

Summary of ISO 12048 Compression Tester Information

The ISO 12048 standard specifies a method for testing the resistance to compression. The testing is of a complete, filled transport package. Additionally, ISO 12048 testing is for carrying out a stacking test such as: ISO 2234 Stacking Tests Using a Static Load. These tests use the same packaging apparatuses.

ISO 12048 evaluates the performance of a package in terms of its strength. The protection a package offers to its contents when subjected to compressive forces can also be assessed by this testing procedure.

The ISO 12048 standard may be performed as a single or sequence of specialized procedures. The single test measures the effects of compression or stacking. On the other hand, the sequence of tests measures the ability of the package to withstand a distribution system that includes compression or stacking hazards.

ISO 12048 Compression Testing Procedures

The specimen being tested is first placed between the platens of a compression tester. In the case of a compression test, a load is applied until failure occurs. In the case of a stacking test, the predetermined load is applied for a predetermined time or until failure occurs.

Compression Test

The package is first weighed and the external dimensions are measured. The package is then placed centrally on the lower platen of the test machine. 

The load is applied by the relative movement of the platens at the appropriate speed. This is done in such a way that peaks in excess of the predetermined load do not occur. In measuring deformations, the initial reading is taken at the initial load.

If required, the predetermined load is maintained for a period of time or until collapse occurs. Then, the load is removed by the movement of the platens.

Stacking Test

The ISO 12048 stack testing method proceeds almost the same as the method above. Information to be noted is that the transport package is filled to resist external compression loads applied during stacking. A tester with one fixed platen is preferred.

Once the load is removed from the specimen, that package integrity is then examined. If a collapse has occurred, the dimensions and contents are measured and recorded.

The ISO 12048 performance test is used to model stacking in which the test investigates performance under particular conditions of load. An example of this package performance test includes when the bottom package in a stack rests on an open-decked pallet.

Information within the test reports include, but is not limited to:

  • Whether a compression or stacking test was carried out.
  • Number of replicate packages tested.
  • Full description of the package, including dimensions, structural and material specifications, and its fittings.
  • Description of any contents.
  • Mass of the package and mass of the contents.
  • The attitude in which the package was tested.
  • Location of measurement points on the packages and stage of the test at which measurements were made.
  • Test conditions, i.e.: the rate of application of the load, the load applied, and the duration of the applied load to the package.

Significance of ISO 12048 Stacking and Compression Testing

ISO 12048 provides guidelines for testing the performance and integrity of packaging materials and systems. The standard covers a wide range of packaging types, including boxes, bags, containers, and more. By adhering to ISO 12048, manufacturers and suppliers can evaluate their packaging solutions to ensure they meet the required quality standards and regulations.

By subjecting packages to these tests, manufacturers can identify weaknesses or vulnerabilities in their packaging design and make necessary improvements.

Additionally, efficient supply chain management relies heavily on robust packaging solutions. Packaging that fails during transit can lead to delays, losses, or damages. ISO 12048 package testing helps identify potential weaknesses in packaging design or materials that may compromise the product’s safe passage through the supply chain.
