SERVICE TESTS CHARACTERIZE the performance of materials in specific applications and should mimic the environment of the actual application as much as possible. This includes simulating the chemical composition of the atmosphere, the temperature and thermal cycle profiles, stress states, fatigue conditions, and design. These tests may be accomplished by exposing test racks to actual service conditions or through the use of prototype apparatus designed and constructed to duplicate the end-use application. Additionally, laboratory service tests designed to evaluate the effect of one or more critical aspects of the exposure conditions may be employed. Service test data enable one to determine failure mechanisms, component or material life, or to screen materials for an application.
