What is Rotational Flat Drop Package Testing?

Rotational flat drop testing evaluates the integrity of unitized loads and large shipping crates and cases during rough handling. This test type will also provide clarity and useful information pertaining to the design of the container and its integrity.

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

When packages do not meet the requirements, we assist with finding solutions. Keystone Package Testing takes a consultative approach throughout the entire test program. Also, Keystone creates an accurate test plan to eliminate expensive over-testing.

Why is Rotational Flat Drop Testing Important?

During testing, damages to products and packages must always be anticipated. Thus, the damages may qualitatively correlate to damage observed in the actual distribution handling system.

This test method will allow the user to determine the integrity and stability of a load. Additionally, it assists with improving the design of the shipping container where deficiencies are found.

Damages to products and packaging during distribution can bring about expensive replacement fees. A rough transportation system can also result in lost customer loyalty, a decline in sales, and production interruptions and delays. Many of these costs can be significantly reduced or eliminated with the proper testing and certification.

Package testing ensures 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 Flat Drop Integrity Procedures

First, a sample is chosen to represent an accurate portion of the units being tested. The unit(s) chosen are then conditioned to ASTM D4332: Conditioning of Containers, Packages, or Packaging Components.

The rotational drop test is completed using a measuring device and a flat rigid surface such as concrete or steel. The test is performed by raising one of the sides of the product 9 inches off the ground, then releasing it quickly so that it free falls to the ground.

The rotational flat drop test sequence calls for multiple drops of the product on predetermined sides and orientations that are detailed in the standard. This standard test method is considered a shock test.

On the other hand, a full rotational drop test is carried out on flat or elongated packages. The product is placed so that one of the smallest faces rests on a flat, rigid surface. Sufficient force is then applied to the upper half of the product so that the product falls on its face without moving it from its position. This test is to be performed in multiple different orientations.

Lastly, a report is written with the following information. This list is not intended to be all-inclusive.

  • Condition of the test item(s) after the test
  • Date, time, and name of engineer conducting the test
  • Description of the equipment used to conduct the test
  • Description of the contents
  • Description of the test procedures used, angle of the drop, and height of the drop.
  • Dimensions of the case, crate, or unitized load

Keystone’s Rotational Flat Drop Equipment and Capabilities

Many companies find that with other laboratories, they face over-testing. I.e: When a lab tests more products than necessary. Keystone does not over-test. We work with companies to find qualifying exemptions because we have your best interest in mind. Our engineers constantly seek to develop long-term relationships with our customers.

In addition, our test machines are capable of precise drops from different heights and angles. 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 sizable pieces of equipment. Our package testing laboratory includes multiple compression testers and shakers up to 12 kips.
