In many cases, OREDA provides separate failure rate estimates for different severity classes as well as failure rate estimates for each failure mode reported within a severity class. OREDA estimated failure rates are for sub(systems) consisting of several different devices within a defined boundary. On the other hand, FMEDA provides predictions for describes how various OREDA data were used to identify failures reported by OREDA under the critical severity class that are not accounted for by FMEDA analysis summarizes the results for mean and 90% confidence limits for OREDA failure rates recomputed after some OREDA failures, not accounted for by FMEDA, are eliminated The use of relevant failure data is an essential part of any quantitative reliability analysis. It is also one of the most challenging parts and raises a number of questions concerning the availability and relevance of the data, the assumptions underlying the data and what uncertainties are related to the data. FMEDA data is for a specific product design, and OREDA data is for a category of products Any competent failure data analyst, including the experts at exida, must consider the worst design example when publishing failure data for a generic class of devices. Some designs have much greater failure rates than others. exida’s SILSafeData tables are based on data from three field failure studies and over 350 billion unit operating hours of manufacturers field return data.

fThis paper is a continuation of two papers presented at ESREL 1995 4 and ESREL 1996 7 conference. 1998-05-01 · OREDA failure data on gas turbines are utilised giving estimates for critical failure rates as a function of the preventive maintenance interval r, and the critical failure rate given that no preventive maintenance is performed (as r - -, this is denoted "the naked failure rate").

§ Offshore Reliability Data(OREDA) contains data from a wide range of components and systems used in offshore oil and gas installations § MechRel is an open reliability data source developed for mechanical equipment by the Naval Surface Warfare Center.

Finding meaningful and accurate failure data and failure rates is one of the key challenges of SIS engineering. According to IEC 61511 2 nd edition: “ The lack of reliability data reflective of the operating environment is a recurrent shortcoming of probabilistic calculations ” (11.9.3 note 2).
