Mark I think you are looking for the NSWC mechanical model for prediction. Most of the proprietary software packages support this.

From: Mark Hone [mailto:[email protected]] Sent: 29 October 2008 11:15 To: [email protected] Subject: Reliability: MTBFs and Probability of Failure Dear All, I am most embarrassed to say that I can't find in my saved emails or in a search of the EMC-PSTC archives or in Google search, a reference I think I once saw to a Mil Handbook that helps with calculations of MTBFs for mechanical items. I'm sure someone has mentioned it in the same breath as Mil Hdbk 217F. Can someone help me with a reference, please?! And any book recommendations on the subject (preferably titled "The Idiot's Guide to...")? For your interest, we're doing some safety assessments (to IEC 61508) of a new piece of equipment with a view to achieving an appropriate SIL rating.
