Force and Seal Evaluation of Elastomeric O-Rings
The purpose of this program is to measure the force on an elastomeric O-ring while it is compressed and held at constant thickness during cool-down from room temperature to 76°K. The O-ring functions as a seal during the test, and the force and temperature at which a leak begins is noted. In addition, the force-temperature curve is continuously recorded so that not only the end points but the shapes of the curves for various elastomers can be compared.
