Abstract
The claimed method and system develops accelerated aging test protocols for a component of a process control device, such as a polymeric component of a valve assembly, where the accelerated aging test protocol is specifically developed in response to expected operating conditions to be used during operation of the process control device in a process plant installation. Test data from the developed accelerated aging tests is analyzed to determine a projected lifetime profile of the component that profiles the component through failure under those expected operating conditions. Particular profiling for polymeric features includes oxidation failure profiling and other fatigue conditions.
