ISTA Package Testing: Do It BEFORE You Ship Your Product [Podcast]
Key Drop Test Standards: ASTM and ISTA
Two major organizations shape the guidelines for drop testing: ASTM International and the International Safe Transit Association (ISTA). These standards are designed to assess packaging strength and ensure products can endure the challenges of shipping and handling.
ASTM D5276: Free Fall Drop Test
ASTM D5276 is the go-to standard for testing packages weighing 110 lbs or less that are typically handled manually. This test mimics the drops that packages endure during shipping, storage, and delivery.
The procedure involves dropping packages from specific heights onto a rigid surface, like concrete or steel. The drop height depends on the package weight: up to 20 lbs are dropped from 30 inches, 21–40 lbs from 24 inches, and 41–60 lbs from 18 inches.
What sets this standard apart is its orientation-specific testing. Packages are dropped on their faces, edges, and corners to pinpoint weak spots. Most packages undergo five drops in different orientations, offering a thorough test of their durability. After each drop, inspectors examine both the packaging and its contents for damage, documenting any issues. Similarly, ISTA protocols incorporate drop testing into their broader transit simulations.
ISTA Series: Safe Transit Testing Protocols
ISTA standards take a more comprehensive approach, combining drop testing with other methods to simulate the entire shipping process. Unlike ASTM, which focuses on individual drops, ISTA replicates full shipping journeys through pre-shipment testing.
- ISTA 1A is the basic standard for products weighing 150 lbs or less. Along with drop tests, it includes vibration and compression tests to mimic the full shipping experience, including warehouse handling.
- ISTA 2A is tailored for less-than-truckload (LTL) shipping, where packages face more frequent handling. This test involves edge and corner drops from heights up to 12 inches, reflecting the typical impacts seen in LTL scenarios.
- ISTA 3A focuses on unitized loads and palletized shipments. It includes drop tests simulating forklift handling and dock-to-dock transfers. These tests emphasize the stability of palletized loads rather than individual packages, using lower drop heights.
ISTA protocols combine drop tests with vibration and compression testing. This integrated approach evaluates how packages perform when exposed to multiple stresses, offering a realistic picture of shipping conditions.
Other ASTM Standards
ASTM offers additional standards for specialized packaging needs, addressing scenarios not covered by D5276.
- ASTM D6179 targets unitized loads and transport packages that exceed D5276's weight limits. Instead of free-fall drops, it uses incline impact tests to simulate the handling of heavier loads.
- ASTM D880 focuses on controlled impact testing for shipping containers. This method allows for precise force measurements, making it ideal for fine-tuning packaging designs before full-scale testing.
- ASTM D4169 provides a complete distribution cycle simulation, incorporating multiple drop test methods. Companies can customize this standard to match their specific shipping conditions by selecting relevant tests from the ASTM library.
- ASTM D7386 addresses temperature-sensitive products, recognizing that packaging materials behave differently under extreme conditions. This standard requires testing packages after conditioning them at specific temperatures, exposing vulnerabilities that might not appear during room-temperature tests.
These standards collectively offer a detailed framework for testing and improving packaging. The choice of standard depends on factors like package weight, shipping method, environmental conditions, and specific industry needs.
Drop Test Methods and Procedures
Accurate drop tests demand careful planning, precise execution, and detailed evaluation to mimic real-world scenarios effectively.
Preparing for a Drop Test
Before testing, packages should be conditioned at 73°F ± 4°F and 50% ± 5% humidity for 24 hours. This step ensures the materials reach their natural moisture balance since factors like humidity can impact the performance of packaging materials such as cardboard.
Each test package must include the actual product or a substitute that matches the weight and weight distribution of the original item. Testing empty packages is ineffective because they lack the internal forces present during real drops. Additionally, test specimens must be sealed exactly as they would be for shipping, using the same tape, adhesives, or closures.
To streamline testing, label each face, edge, and corner of the package clearly with permanent markers. A standard practice is to number the six faces and mark the specific drop points, ensuring all required positions are tested and results are accurately documented.
Before starting, ensure all equipment is calibrated. The drop apparatus should be properly aligned, and the impact surface must be clean, level, and meet standard requirements. Most guidelines specify a rigid concrete floor at least 4 inches thick or a steel plate mounted on concrete. The impact area should be large enough to fully accommodate the package during the drop.
Once everything is prepared, attention shifts to executing the drop test with precision.
Executing the Drop Test
With specimens ready and equipment calibrated, the drop test follows a strict protocol. Drop height must be measured from the lowest point of the package to the impact surface, ensuring accuracy. For ASTM D5276 standards, packages weighing up to 20 lbs are dropped from a height of 30 inches, while heavier packages have proportionally lower drop heights. The release mechanism must allow the package to fall freely, avoiding any added forces or rotations.
The test sequence typically involves five drops: one on the weakest face, one on the strongest face, one on the longest edge, one on the shortest edge, and one on the most vulnerable corner. This approach ensures all critical structural elements are tested for potential failure points.
Environmental conditions, such as temperature and humidity, must remain within the specified ranges throughout the test. If conditions deviate, testing should pause until they stabilize. Some facilities use climate-controlled chambers to maintain consistent conditions during testing.
Every drop must be carefully documented in real time. Record the exact drop height, package orientation, impact location, and any visible damage immediately after each drop. Photos should be taken before testing begins and after each drop to provide a visual record of the package’s condition.
After completing the drop sequence, the data collected is used to evaluate the package’s performance.
Evaluating Test Results
Once the drop tests are complete, the results are analyzed to assess damage. This includes a visual inspection of both the packaging and its contents, focusing on external and internal damage. The evaluation differentiates between cosmetic damage (minor dents or scuffs) that doesn’t affect the package’s protective capabilities and functional failures that compromise its structural integrity.
Pass/fail criteria vary depending on the product and test standards. Generally, a package passes if it maintains its structure and protects the contents from damage. Cosmetic issues like small dents are usually acceptable unless they interfere with the package’s protective function. However, problems like seam openings, significant deformation, or damaged contents typically result in failure.
When failures occur, it’s important to identify the root cause. For example, weak adhesives or insufficient material thickness might be the issue. Understanding these causes allows engineers to make targeted design improvements rather than resorting to unnecessary material increases.
To ensure reliable data, test at least five samples per design. A single failure might indicate a manufacturing defect, but consistent failures across multiple samples highlight design flaws that need to be addressed.
Finally, companies often compare lab test results with real-world shipping performance. If field damage rates exceed expectations, the testing protocols may require adjustments to better replicate actual shipping conditions.
The insights gained from drop test data play a critical role in refining packaging designs and maintaining quality control standards.
