Values in this workbook are synthesized estimates, consistent with order-of-magnitude ranges reported in IEC 61709, IEC 62380, SN 29500, MIL-HDBK-217F, MIL-HDBK-338B, FMD-2016 and FIDES. They have not been taken from or verified against the licensed documents, which are copyrighted. The values are intended as placeholders and sanity-check figures until replaced with licensed or vendor-supplied data for a specific analysis. The purpose of this workbook is to allow safety and hardware engineers to populate preliminary FMEDA (FIT) and MTTFD (year) failure modes and estimates in building their calculation worksheets until more refined calculations are required.
