Abstract
Equipment and techniques for evaluating the stability, creep, and sealability of gasket facing materials at high temperatures are presented. Mathematical models for predicting long-term failure of elastomer-bonded gaskets from short-term high-temperature tests were used. The value of differential thermal analyses and differential scanning calorimetry in the ranking of facing compositions and alternatives to engine testing to establish confidence in screening gasketing materials are the projects presented.

- High-temperature creep experiments were run using a 75 mm O.D. x 55 mm I.D. ring sample held under constant load while the temperature was increased at 10°C/minute. Three replicates constituted a single test
- Sealability was run at the listed temperatures with a 90 mm O.D. x 50 mm I.D. test ring under various clamp loads at an internal pressure of 580 psi. Four replicates constituted a single test
