ISO 12048

Package Compression Testing

Introduction

ISO 12048 is a widely recognized international standard that specifies test methods for the compression and stacking performance of complete, filled transport packages. It plays a crucial role in assessing packaging durability, particularly for fragile or critical goods, including infusion bags used in medical settings.

As product safety and compliance become more demanding, especially in medical and pharmaceutical logistics, ISO 12048 offers a clear methodology to evaluate whether a package can withstand mechanical pressures during storage and transit. This standard underpins many testing protocols, including package compression test, a key method for simulating real-world stresses.

Why Package Compression Test Matters in Packaging Durability Assessment

The package compression test, guided by ISO 12048, simulates vertical stacking forces a package may face during warehousing and transportation. When combined with environmental pre-conditioning (23±2℃, 50±5% RH for ≥24 hours), this test can offer valuable insights into both structural integrity and functional reliability.

High-value sectors such as pharmaceuticals, food, and medical devices rely on packaging to protect against contamination and mechanical failure. The packaging durability assessment helps ensure the product’s sterility and usability remain intact from production to point-of-care delivery.

Common metrics measured include:

Initial deformation point (onset of structural compromise)
Total crushing point (maximum resistance threshold)
Deformation limits (e.g., height drop ≤10%, or ≤5% for infusion bags)
Functional failures (seal rupture, leakage)

Cell Instruments’ PCT-01 offers highly accurate results aligned with ISO 12048. With a force measurement error within ±0.5% and a platen parallelism deviation of ≤0.05%, it guarantees uniform load distribution. It also supports reduced loading speeds below 5 mm/min for fragile materials like soft film infusion bags.

Infusion Bag Compression Test: A Special Case of ISO 12048

The infusion bag compression test is a specialized subset of package compression testing. Due to the soft and flexible nature of medical-grade film, such packages are particularly vulnerable to deformation and rupture. ISO 12048 offers a robust testing framework, and in many cases, it’s integrated with YY/T 0681.3, which focuses on leak testing in sterile barrier systems.

Important testing points include:

Height drop limits (≤5% for soft packs)
Seal integrity and fluid leakage evaluation
Load application using speed < 5 mm/min
Calibration compliance with ISO 7500-1

PIT-01P’s low-speed precision control and flat platen design (Ra ≤3.2μm) make it ideal for such sensitive applications. Test results are output as a pressure-deformation curve highlighting key failure modes, including content leakage or structural collapse.

Test Methodology and Reporting: Following ISO 12048 Protocol

Compression Test Method:

Sample Conditioning: Maintain samples under controlled conditions (23°C ±2 / 50% RH ±5) for at least 24 hours.
Loading Method: Apply load vertically using constant speed (10 ±3 mm/min; slower for delicate materials).
Data Capture: Monitor and record the pressure-deformation curve.
Evaluation Criteria: Mark initial deformation, crushing point, and check for functional issues like leakage.

Reporting Requirements:
According to ISO 12048 and industry best practices, the report should include:

Test environment details
Loading speed
Plate dimensions
Deformation thresholds
Failure type (structural or functional)
Graphical output of compression curve

Cell Instruments’ PCT-01 supports automated data logging and graphical analysis, ensuring compliance and reproducibility.

Enhancing Packaging Durability Through ISO 12048 Testing

In competitive sectors like electronics, beverages, daily chemicals, and healthcare, package failure is more than a minor issue — it can lead to contamination, financial loss, or patient risk. ISO 12048-compliant testing, therefore, isn’t just a regulatory checkbox but a strategic tool for quality assurance.

Whether you are validating a new cardboard structure, analyzing multi-layer film behavior, or qualifying a medical infusion bag, following ISO 12048 helps elevate your packaging reliability.

For customers needing custom test development or automation transformation, Cell Instruments offers tailored solutions based on the PIT-01P and a wide suite of precision testing platforms.

Conclusion

By centering packaging evaluation around ISO 12048, manufacturers can ensure their products meet global standards for compression resistance and durability. In fields like infusion bag compression test or packaging durability assessment, compliance not only guarantees product protection but also enhances customer trust.

For dependable, ISO-aligned testing solutions, the Cell Instruments PCT-01 stands out — delivering precision, flexibility, and professional-grade support for industries that demand nothing less than excellence.
