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 t

Colleagues - May I thank everyone who has Emailed me both directly and though the mailing list, for the help they have provided. In just five-and-a-half hours I have received enough links and pointers to keep occupied solidly for a week or two reading it all. With thanks again, Mark

Predicting the reliability of mechanical systems is much more complicated than for electrical systems. Part of the trouble is that there are often more uncontrolled variables in mechanical systems. You may find some information on mechanical predictions in the electrical reliability sources, but
