Step by step procedures will be developed which provide for the detailed evaluation of electronic, mechanical and pyrotechnic devices with respect to the effects of long term storage. These procedures will provide for theoretical (paper) evaluations of these elements, as well as storage containers, specifications, and production procedures, which may lead to additional physical evaluations and tests. Because of the wide variety of fuse types, these _procedures will provide outlines for the preparation of physical evaluations and test procedures. Problems isolated by this methodology will provide the basis for recommending corrective action. When required, verification tests, such as thermal shock, accelerated life and pressure cooker tests, will be performed during phase II.
