Abstract
Standard test methods, such as ASTM C719, evaluate sealant performance though threshold test measurements. This method and its derivatives do not offer reliable predictions of in-service performance. This article will detail efforts to move away from the use of threshold tests towards a reliability-based method for predicting the service life of sealant materials. The central role of dose-damage based models in this approach is explained. The first task is designing a method to monitor the damage to a sealant through changes in the mechanical properties. Changes in the cross-link density of a sealant are monitored during cure by measuring changes in the tensile modulus.
