Compression & Deflection
Testing a material’s sealing force retention or ability to maintain elastic properties after compression is routinely performed at ARDL. Compression testing begins with the determination of the appropriate deflection or the constant force a material will be subjected to according to the requirements given. Materials may also be exposed to a variety of fluids and environments while under compressive forces.
ARDL regularly measures customer materials’ performance under load deflection according to industry standards. ARDL follows the specifications and customer requirements to determine a compressive load or force for the customer’s application. Testing is performed by measuring the thickness of the material after being placed between two platens and a specified load placed on the material. A force stress/strain curve can also be recorded.
