JING-JIN-JI Institute of Remanufac.turing Industry Technology) Abstract： The remanufactured object is part that undergoes one or more service cycles. Whether the part has remaining life and its remaining life can be adapted to the next service cycle is problem that should be solved first before manufacturing. The goal of the remanufacturing project is to make the remanufactured products reach or exceed the new products through remanufacturing, and if the parts that have no remaining life without life evaluation will be used again, which will bring losses to users and enterprises. This paper introduces the importance of life assessment for the development of remanufacturing industry, and elaborates on the principles, preparation process and main contents of GB/T34631-2017, Remanu£acturing-The residual life assessment guidelines of mechanical components. It clarifies the technical points and precautions of the standard, indicating the importance of developing the standard, to help
