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 this paper, a prognostics-based qualification is proposed, which is more efficient and cost effective than the traditional qualification process. 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, this paper, a prognostics-based qualification is proposed, which is more efficient and cost effective than the traditional qualification process. 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.
