This can be done by staying well below the creep limit, which is defined as the stress to which a material can be subjected without the creep exceeding a specified amount after a given time at the operating temperature (for example, a creep rate of 0.01 in 100,000 hours at operating temperature).

Stress rupture testing is similar to creep testing except that the stresses used are higher than in a creep test. Stress rupture testing is always done until failure of the material. In creep testing the main goal is to determine the minimum creep rate in stage II.

3. Using the creep test procedures in the load frame control system, conduct one creep test on a specimen of each material, recording the stress and strain as a function of time. After the sample is removed from the load frame, measure its length and diameter immediately, and then after every 5 minutes for the next hour.

I am worried about creep in this application. My vendor has recommended moving to a 90 durometer FKM, which has a slightly higher compression set than the 75 durometer material. My questions; - is there a correlation between creep and compression set?

Previous studies of how material creep parameters can be measured by nanoindentation testing have focused mostly on how one can determine the stress exponent for creep, n, and the activation energy for creep, Q. However, a more complete characterization requires that the material constant A in the uniaxial creep...
