Immediate Action Required: ASTM D4169-23e1 Introduces Tougher Testing for All Existing Packaging

ASTM D4169, the gold standard for transportation simulation testing of packaging, has undergone significant revisions with its latest updates, ASTM D4169-23 and ASTM D4169-23e1. These updates introduce stricter H-Factor and compression load requirements, ensuring that all packaging previously certified under older versions must now be rigorously retested to meet these enhanced standards. This article highlights the critical changes that reflect the latest advancements in packaging technology and regulatory requirements, particularly essential for sectors like biomedical, where safety and compliance are paramount.

Overview of Recent Changes to ASTM D4169

Recent revisions to ASTM D4169 have incorporated significant modifications, including:

Conditioning References: Addition of ASTM F2825 for more relevant climatic stressing
Compression Load Adjustments: Updates to the H-Factor and compression values, specifically increasing the default shipping density from 10 lb/ft³ to 12 lb/ft³, impacting how compression tests are conducted
Reclassification of Packages: New definitions for small or lightweight packages, affecting their testing protocols and standards

Detailed Analysis of New Standards

Conditioning References

The inclusion of ASTM F2825 for climatic conditioning represents a significant shift in testing protocols. Unlike the previous references to ASTM D4332, which provided general guidelines for conditioning based on broad temperature and humidity ranges, ASTM F2825 targets specific climatic stressing of packaging systems intended for single parcel delivery. This change ensures that the conditioning phase of testing is more closely aligned with the actual environmental conditions that packages are likely to encounter during shipping, leading to more accurate testing outcomes and better preparation for real-world conditions.

Compression and Stack Heights

Changes to H-Factor: Previously, ASTM D4169 allowed for adjustments in stack height based on the size and weight of the package, which directly influenced the compression load applied during testing. With the latest revision, certain exceptions for reducing the stack height have been removed, specifically the note that allowed smaller stack heights for lighter packages. This means that all packages are now subject to a uniform stack height of 108 inches in the calculation, increasing the compression load for smaller, lighter packages.

Increase in Compression Values: The update from a default shipping density of 10 lb/ft³ to 12 lb/ft³ for unknown densities marks a 20% increase in the compression load. This change is intended to better reflect the stresses encountered during transportation, especially given that actual shipping densities can vary widely. The new standard helps ensure that the testing is robust enough to prevent damage during shipping, accommodating for worst-case scenarios more effectively.

Safety and Integrity Enhancements

The ASTM D4169-23 standard’s updates contribute significantly to the safety and integrity of shipping containers. By refining testing parameters to better match real-world conditions and potential risks, the standard helps ensure that packaging can reliably protect its contents against the rigors of transport. For instance, the increased compression load requirements mean that packaging must be designed to withstand greater forces, which can help prevent failures in the field. Furthermore, the consistent application of a higher stack height in testing reflects a conservative approach, preparing packaging for extreme stacking scenarios that might occur during mishandled or over-stacked shipping processes.

These detailed expansions provide a deeper insight into how the changes in the ASTM D4169-23 standard affect packaging testing, ensuring that stakeholders can better prepare for compliance and optimize their packaging designs accordingly.

This past weekend, two of my key engineers were at your facility working a highly visible and critical program for Northrop Grumman, the ATFLIR program supporting the FA-18s. I wanted to pass along my sincerest thanks to you for arranging support at your facility, and most particularly to the two gentlemen, Dan Gordon and Bernie Cameron, who worked with us on Friday, October 13th and Saturday, October 14th. Without their professional assistance and support, we could not have managed to achieve all that we did in such a short time or on such short notice. Both should be commended for providing top notch level of support. I have been told by both Northrop Grumman engineers who were at your facility that Dan and Bernie gave 110% effort. Please express to each our thanks, not only for their support, but for giving up a part of their personal time on our behalf.

Lorrie Gampp, ATFLIR 1550 Program Manager, Northrop Grumman

I would like to express my appreciation for the support I received from your organization on our latest round of testing last week of the APR-39A Receiver Assemblies. I would especially like to thank your technical staff, particularly Dan and Bernie, for successful test profiling and after-hour support on a holiday weekend. Timely completion of the testing sequence represented approximately 400K in end of year sales for our Littleton Operation. Thanks again and I look forward to future programs with your organization.
