ABSTRACT
This chapter describes the basic terminology and process used in FMEA. In addition, the procedures for setting up, conducting and following up FMEA are described.
Introduction Similar to a HAZOP, the FMEA is a bottom-up approach starting with components and using a single-point failure approach to progressively work up to the top level. During the FMEA study, risk is estimated by rating the severity of failure effects, the likelihood of causes, and the likelihood of detecting the cause of a failure or the failure mode. Table 6-1 shows a sample FMEA worksheet for documenting the result of the analysis. The terminology used on the worksheet and the FMEA procedures are described below.
