Subject: Field Factors on MTBF
About three years ago I read and kept the formulas for converting MTBF to a field factor for ground vehicle and hand held devices from a RADC report. I can not find the report or a reference to the report, but I still have and use the formulas.
Do you know the reference?

The formulas that were developed for converting predicted and tested MTBFs(mean-time-between-failure) are contained in the Technical Report RADC-TR-89-299, Reliability and Maintainability Operational Parameter Translation II, dated December 1989. Excerpts from this report are included in the Reliability Toolkit, Commercial Practices Edition that show the formulas and examples. This toolkit is available from our product catalog. The technical report is available from the Defense Technical Information Center, Ft. Belvoir, VA.
