Abstract: Qualification is the process of demonstrating that a product is capable of meeting or exceeding specified requirements. The specified requirements are expected to depend on the final product and its specific life cycle application conditions. In most cases, the traditional qualification process has not been efficient or cost effective. In this paper, a prognostics-based qualification is proposed. The approach does not require a product to fail in the test, because in addition to detecting failure, the health of the product is monitored, including degraded health and intermittent product disruptions. The results are a significant decrease in qualification time and much improved understanding of the product’s reliability.
