What is Horizontal Compression Integrity Testing?
Horizontal compression package testing evaluates the ability of a container to resist external compressive loads. Compression testing may also be used to:
- Compare the characteristics of a given design of a container
- Assess the package in terms of strength and how well it offers protection to its contents
Keystone Compliance realizes the importance of horizontal compression integrity testing. Meeting compression testing requirements can be difficult. We understand the challenges and guide companies through the process.
Why is Horizontal Compression Testing Important?
This test type determines a shipping container’s ability to successfully survive real-world compressive forces. These compressive forces are found during storage and/or the distribution process.
Poorly packaged products can be expensive and lead to unwanted costs. Other negative attributes include loss of customer loyalty, a decline in sales, and constant interruptions and delays.
On the other hand, the benefits of package testing to withstand the transportation cycle may include:
- Balanced distribution costs
- Confidence in product launch
- Increased customer satisfaction and a growing market share
- Product to market time reduction
Horizontal Compression Compliance Testing Procedures
Depending on the test method being performed, the package is either conditioned with ISO 2233: Complete, filled transport Packages and Unit Loads – Conditioning for Testing or ASTM D4332: Conditioning of Containers, Packages, or Packaging Components.
Next, a sample size is chosen. This must accurately represent the units manufactured.
The horizontal compression test is completed by either using a clamp tester or a compression machine. If the clamp tester is used, the platens must be larger than the side dimensions of the test item. An opening must be sufficient to accommodate the test item.
If a compression machine is used, the rigid load applicator must be larger than the test sample face to be tested. A rigid load applicator can consist of a piece of plywood or steel plate. The horizontal compression test is performed by applying a predetermined amount of force to predetermined faces of the product.
After the testing is completed, a report is written including the following information:
- Description of the contents
- Description of the interior packaging (if used)
- Detailed test results for each specimen
- Number of specimens tested
- Identification of test apparatus and instrumentation used
Keystone’s Compression Testing Equipment and Capabilities
Keystone’s package testing laboratory includes multiple compression testers and shakers up to 12 kips. Additionally, our test machines are capable of performing precise drops from different heights and angles.
We use dozens of 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 Compliance owns all the equipment needed to perform professional package integrity testing. We can test flexible and rigid packages of all sizes. Furthermore, we are an ISO 17025 and ISTA-certified test facility that offers the peace of mind that all your package testing needs are met under one roof.
Expert Horizontal Compression Package Testing Laboratory
In addition to horizontal compression testing, Keystone has a full scope of expertise including sterile barrier, altitude, and cold chain. Our team strives to give our customers more time and energy on product development instead of testing.
