Rotational Corner Integrity Testing

What is Rotational Corner Drop Testing?

Rotational drop testing evaluates the integrity of a unitized load, large shipping cases, and crates. More specifically, rotational corner drop testing helps determine the ability of the contents inside the shipping system to endure rough handling.

As an ISTA and ISO 17025 certified lab, Keystone Package Testing realizes the importance of corner drop integrity compliance. Meeting specified rotational corner drop testing requirements can be difficult. We understand the challenges and guide companies through the process. 

Keystone takes a consultative approach throughout the entire test program. When packages do not meet the requirements, we assist with finding solutions. Keystone Package Testing partners with customers to achieve package compliance.

Why is Rotational Corner Drop Integrity Testing Important?

Rotational corner drop testing measures the ability of a case, crate, or unitized load to withstand rough handling. This testing provides useful information for improving the design of a packaging system.

Damages to products observed during testing qualitatively correlate with damage found during the actual transportation cycle. Damages to packaging during distribution can also bring about expensive replacement fees. A harsh distribution system results in a decline in sales, lost customer loyalty, and constant interruptions and delays. Many of these costs may be significantly reduced or eliminated with the proper testing and certification.

Package testing will ensure packaging integrity throughout transportation to mitigate risks. When correctly performing bridge impact integrity compliance testing, benefits will include:

  • Product to market time reduction
  • Confidence in product launch
  • Reduced damages and product loss
  • Balanced distribution costs
  • Increased customer satisfaction and a growing market share

Rotational Corner Drop Testing Procedures

Before testing, several cases, crates or unitized loads are chosen to accurately represent the units. The same test item may often be used for all applicable tests if not tested to failure. This test type recommends conditioning the units per ASTM Method D4332: Conditioning Containers, Packages, or Packaging Containers for Testing

The rotational corner drop test is completed using a measuring device, a support block, and a flat rigid surface such as concrete or steel. The support block is 3.5 to 4.0 inches in height and width and at least 8 inches longer than the longest package dimension to be supported.

To perform the test, one of the corners of the product is placed on the support block. The opposite corner is lifted 9 inches and then released quickly, allowing it to free fall to the rigid surface.

The test sequence calls for multiple drops of the product on specific corners. If the product, while in a particular orientation, topples over before a corner can be lifted to the required support or drop height, then the rotational corner drop test is not possible.

After the testing has been completed, a report is written with the following information.

  • Dimensions of the case, crate, or unitized load
  • Description of the contents, if simulated or dummy contents are used, details are given
  • Condition of the test item(s) after testing
  • Description of any damage
  • Detailed record of tests including procedures used, angle of drop, and height of drop

Keystone’s Rotational Drop Equipment and Capabilities

Keystone’s test machines are capable of precise drops from different heights and angles. Furthermore, our package testing laboratory includes multiple compression testers and shakers up to 12 kips.

We utilize more than two dozen climatic chambers with sizes ranging from reach-in to large walk-in chambers up to 1,300 cubic feet. These thermal chambers can accommodate up to entire vehicles and substantial pieces of equipment. Keystone can test flexible and rigid packages of all shapes and sizes.
