New White Paper Describes exida’s Most Detailed Field Failure Study to Date
October 06, 2020
exida has just released a new White Paper describing their most detailed field failure study to date. A comparison between exida’s Calibrated FMEDA process and OREDA failure reports has been performed on a specific manufacturer/model number valve. The comparison was accomplished with unprecedented access to unpublished failure reports from the latest OREDA database.
“We wish to acknowledge with gratitude the gracious support of the OREDA organization which provided detailed data for gate valve assemblies from its database,” said Dr. Julia V. Bukowski, who performed the analysis. She added “We also thank OREDA personnel for their efforts in reviewing the research results.”
Dr. William Goble said “We have been enhancing our Component Reliability Database (CRD)TM for nearly twenty years. This database is used to perform FMEDA analysis on automation devices to predict failure rates, useful life, and proof test coverage. The results show a strong match between actual field failure data and the Calibrated FMEDA predictions.”
A copy of the White Paper showing the derivation of the results is available here.
