The Future of Failure Data

Although product specific FMEDA reports offer superior data sources when compared to industry databases, they still do not account for application specific stress conditions that may affect actual failure rates. Ideally in the future manufacturers will be able to provide not only point estimates of failure rates but perhaps even equations with application specific variables to more precisely calculate the needed numbers. That wiU happen if there is demand and the needed data is collected. [Pg.122]

One effort in the right direction is the PERD (Process Equipment Reliability Database) initiative (Ref. 10) from the Center for Chemical Process Safety (CCPIS) of the AIChE (www.aiche.org/ccps/perd/). That [Pg.122]
