The selection of Mission Time, Proof Test Interval and Proof Test Coverage is very important when it comes to the PFDavg achieved by Low Demand SIFs. Oftentimes, people don’t realise the impact Mission Time can have on the PFDavg, especially when considering “Imperfect” Proof Testing. This is why it’s so important to utilize realistic Proof Test Coverage when considering the SIF. There is no such thing as “Perfect” Proof Testing, which indicates being able to find and fix all dangerous failures. These variables must be based upon End User practices and not just arbitrarily set by the SIS designers. The purpose of this webinar is to illustrate the relationship between these variables and the impact they can have on the overall SIF PFDavg, utilizing a simple example. What you will learn: • What is Mission Time • How Proof Test Interval and Coverage Interplay with Mission Time • How imperfect proof testing and Mission Time impact PFDavg • Why Mission Time and Proof Test Interval are End User defined • How Mission Time interplays with Useful Life #FunctionalSafety #PFDavg #SIF #ProcessSafety #MissionTime #ProofTest ======================================================== Subscribe to this channel: https://bit.ly/36UM1ok exida Home Page: https://www.exida.com Contact Us: https://www.exida.com/Company/Contact LinkedIn: https://www.linkedin.com/company/exida-com
