Some results are presented of a continuing program at Sandia Laboratories whose main goal is to develop more reliable accelerated aging techniques for testing the effects of aging on materials. An interesting situation in accelerated aging occurs when two or more environmental stresses lead to the deterioration of a component. Synergism is sometimes important in such cases so that the deteriorating effects of the various environments are not additive. A model potentially applicable to combined environment aging is proposed. The model is described and how it can be used to carry out accelerated aging in combined environment situations is indicated. Some preliminary data on the embrittlement of neoprene cable jacketing material aged in single and combined thermal and radiation environments are described and analyzed according to the formalism of the model.
