Colleagues - I have been encouraged to record in a final email what I have discovered with your help in my search for reliability data, so that future searches of the EMC-PSTC archive will turn up the references. The reliability/probability-of-failure figures are needed to allow calculations to confirm the SIL level of a safety critical system comprising both mechanical and electrical parts. Here are the Standards, with a couple of website links too:
Mechanical Reliability NSWC 98 Handbook of Reliability Prediction Procedures for Mechanical Equipment, latest issue and supporting MechRel software package are both available at no charge from the following web site: http://www.dt.navy.mil/tot-shi-sys/pro/rd-pro/mec/index.html NPRD-95 The Non-electronic Parts Reliability Data databook is published by the Reliability Analysis Center and provides historical field failure rate data on a wide variety of mechanical assemblies. This document has to be purchased.
