factor of safety (FOS)
Standard
ECSS-E-ST-32C Rev. 1Definition
factor by which design limit loads are multiplied in order to account for uncertainties of the verification methods, and uncertainties in manufacturing process and material propertiesNotes
- NOTE 1 Factor of safety is synonym of safety factor.
- NOTE 2 FS and SF are also recognized abbreviations used for factor of safety
- NOTE 3 The factor of safety is a combination of factors according to various sources of uncertainties. Its magnitude is based on proven processes and verification methods for analyses, tests and manufacturing. To account for uncertainties of analysis, higher values of factor of safety are normally used for verification by analysis only. Higher values of factors of safety are also used if higher reliability is desired than was taken in the limit load determination.
