D6179-20 – Standard Test Method Technical Guide
📐 Scope and Primary Test Methods Overview
ASTM D6179-20 provides standardized procedures for evaluating the integrity of unitized loads, large shipping cases, and crates when subjected to the rigors of rough handling during material handling and distribution. The standard defines eight distinct test methods (A through H) to simulate various physical handling hazards.
Drop Tests (Methods A, B, C, D, and E): These methods measure the ability of a container to withstand rough handling impacts. While applicable to a broad range of large containers, the standard specifically notes that Test Methods A and B are normally not applied to unitized loads.
Tip and Tipover Tests (Methods F and G): Method F determines if tall or top-heavy cases, crates, or unitized loads will tip over when tilted to a predetermined angle. Method G assesses the protection provided by the container and packaging against tipover impacts. Note: Test Method G fulfills the requirements of ISO 8768, though the reciprocal is not required.
Rolling Test (Method H): This test determines the ability of a complete, filled large shipping case or crate to withstand the effects of rolling during handling. Note: Test Method H fulfills the requirements of ISO 2876.
💡 Technical Note: While Test Method G is harmonized with ISO 8768, the standard explicitly cautions that ISO 8768 may not meet the full requirements of ASTM D6179-20 Method G. Always verify compliance based on the specific contractual standard cited.
| 🟦 Test Method | 📐 Title | 🎯 Primary Application |
|---|---|---|
| A, B, C, D, E | Drop Test | Shipping cases, crates, and unitized loads |
| F | Tip Test | Top-heavy or tall filled containers |
| G | Tipover Test | Large shipping cases (fulfills ISO 8768) |
| H | Rolling Test | Large shipping cases (fulfills ISO 2876) |
⚙️ Units, Conditioning, and Supporting Standards
The standard establishes inch-pound units as the standard for all measurements, with SI units provided in parentheses for information. It is the responsibility of the user to establish appropriate safety and environmental practices prior to conducting the tests. Conditioning of test specimens should be performed in accordance with Practice D4332.
ASTM D6179-20 is part of a comprehensive suite of packaging test methods. Mechanical handling tests for unitized loads are set forth in Test Method D6055. Additional impact simulation tests include the incline impact test (D880) and programmable horizontal impact tests (D4003 and D5277). For designing and testing the pallets themselves, Test Methods D1185 provides the appropriate framework. Practice D4169 offers a complete series of options for selecting and running performance tests on shipping containers and systems, integrating the methods found in D6179.

🌍 International Standardization: This standard was developed in accordance with internationally recognized principles on standardization established by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
❓ Frequently Asked Questions
🔍 What is the primary purpose of ASTM D6179-20?
This standard outlines test methods for testing the integrity of unitized loads and large shipping cases and crates, as well as the ability of their contents to endure rough handling during material handling and transportation.
💡 Which test methods correspond to specific ISO standards?
Test Method G (Tipover Test) fulfills the requirements of ISO 8768. Test Method H (Rolling Test) fulfills the requirements of ISO 2876. The specification notes that the ISO standards may not fully satisfy the corresponding ASTM methods.
⚡ Are all test methods applicable to unitized loads?
No. The scope explicitly states that Test Methods A and B (Drop Tests) are normally not applied to unitized loads. The selection of the proper method depends on the container type (case, crate, or unitized load).
📌 How does D6179 relate to other packaging standards?
It functions as a specific set of rough handling test protocols. It is closely related to mechanical handling tests in D6055 and performance test schedules in D4169, which provides a framework for selecting appropriate tests from methods like D6179.
