Overview
ISO 12048:1994 is an international standard specifying test methods for evaluating the compression resistance and stacking performance of complete, filled transport packages. Developed by ISO Technical Committee ISO/TC 122, this standard provides a clear procedure using a compression tester to apply loads to packages, simulating real-world conditions during storage and distribution. By carrying out compression and stacking tests, manufacturers and supply chain professionals can assess package strength and protection to ensure product safety and integrity during transport.
The standard consolidates previous editions (ISO 2872:1985 and ISO 2874:1974) into one updated document, facilitating uniform testing and reliable performance assessment for filled transport packaging. It is applicable to various packaging types, including boxes, crates, metal drums, and other filled transport containers.
Key Topics
- Compression Testing Method: Applies a gradually increasing load on the package through platens of a motor-driven compression tester to determine the maximum load the package can sustain before failure or collapse.
- Stacking Test Procedure: Applies a predetermined static load to simulate the effect of stacked packages for a specific duration, assessing the package’s ability to sustain load without collapse when stacked during storage or transport.
- Apparatus Specifications: Describes requirements for compression testers, including platen flatness, rigidity, and alignment to ensure uniform load application and reliable test results.
- Test Package Preparation: Guidance on filling packages with intended or simulated contents to replicate actual transport conditions accurately.
- Conditioning Requirements: Recommends that packages be conditioned under controlled temperature and humidity (referencing ISO 2233) to reflect environmental factors impacting packaging performance.
- Test Conditions and Speed: Specifies a loading speed of 10 mm/min ± 3 mm/min during testing to standardize results and prevent load peaks.
- Measurement and Reporting: Instructions for recording load, displacement data, dimensional changes, and any package failure with detailed reporting requirements for traceability and analysis.
- Deformation Measurement: Outlines methods for measuring package deformation during compression tests to assess structural behavior.
- Variations for Different Packaging Types: Notes on adjusting parameters such as loading speed for fragile or rigid packaging (e.g., metal drums or wooden crates) for accurate testing.
