ASTM D1414 Rubber O-Rings: Compression Set of Elastomers
When an elastomer is compressed it will deform. This deformation may be temporary so that elastomer returns to its initial size and shape when the pressure is released, or it may be permanent. A permanent deformation, known as a “compression set”, occurs when the compression force is so great that the elastomer will not return to its initial shape and size. O-rings used as seals in pumps, and other mechanical systems are compressed during normal use to prevent leaks in interfacing surfaces. If compression set occurs, the O-rings may no longer properly stop leaks. This test determines the compression set of elastomers exposed to hydraulic fluids.
Note: Compression set measures permanent deformation of elastomers resulting from a squeezing force. Tensile strength refers to how much an elastomer can be stretched before snapping. Tensile strength describes what happens when an elastomer is pulled apart and compression set refers to what happens when it is pushed together.
