Compression Test Systems
Stacking forces generated during warehouse storage and transit can generate severe compressive loads. Compression tests are an essential part of the package design process. Lansmont offers a full range of Compression Test Systems to determine the performance of unit loads, individual packages, components, and materials under compressive loads. This information enables the engineer to minimize damage, costs, and liability due to stacking failure.
What Is Compression Testing?
Compression testing is a mechanical procedure used to determine how a test sample will react to a force being applied across one side of the test sample. A box compression testing machine applies the compressive force to the container, while holding the container between two plates that distribute the load. Typically, one of the two plates is fixed, while the other is movable. As the dynamic force is applied to one side of the test container, the test system monitors and reports both the force and deflection throughout the duration test.
Packaging Engineers use compressing test equipment to design protective packaging systems that can withstand the compressive forces that packaged products will experience when traveling through the supply chain. Common test items They most often test materials used in a load-bearing capacity where durability under compressive forces is essential, such as:
- Corrugated paperboard and containers
Types of Compression Tests
Compression testing involves at least two opposing forces directed toward each other and applied to opposite sides of the test sample. There are several types of compression testing setups accounting for different combinations of variables.
Four of the most common compression test methods include:
- Top-load testing: Also called crush testing, this method is a quality control parameter that’s used for corrugated boxes, plastic containers, glass jars, and metal cans. Top-load testing replicates the force applied to packaging in its initial production and after it’s filled, closed, stored and transported.
- Testing to failure: A force is applied to one side of a test sample at a constant application rate. That application continues until a predetermined failure condition occurs. Failure is typically associated with a rapid drop in indicated force, caused by structural failure of the test sample. Both the force and deflection at that point of failure are recorded.
- Constant load testing: A predetermined force, or load is applied to a test sample, and held continuously, either for a predetermined time duration, or until a failure condition is met. Failure is typically based upon the amount of cumulative deflection, or creep of the test sample. Both force and deflection are recorded during this testing.
- Flexure testing: Flexure, or bend, testing evaluates a material’s flexural strength by placing a sample horizontally over two supports and applying force to the sample’s surface through one or two points of contact until the material fails.
