This report documents findings on the non-operating reliability of accumulators. The study consists of over 326 million part hours. The sources show an overall storage failure rate of 32.6 FITS failures per billion hours with a one sided 90 confidence limit of 54.8 FITS for hydraulic accumulators. Elements of accumulator design are discussed. This information is part of a research program being conducted by the U.S. Army Missile Command, Redstone Arsenal, Alabama. The objective of this program is the development of non- operating storage reliability prediction and assurance techniques for missile materiel.
