Methodology and interpretation of stability tests as commonly applied when testing elastomers are described. Traditional compatibility screening does not adequately reproduce the operating conditions of many elastomeric seals, such as O-rings for instance. For this reason, compression set testing of mass-produced parts in contact with the operating media is presented here as an effective test procedure. Several examples from real life have made it possible to demonstrate that, even after short testing periods, conclusive indications regarding the selection of materials can be obtained.
