Recorded Webinars: Final Element Proof Tests
Proof test coverage is an important variable in Safety Instrumented System design that can impact risk reduction by an entire SIL level. This is shown in PFDavg calculations. Most engineers who design and verify safety instrumented functions (SIFs) understand how hard it is to design a manual proof test with high effectiveness (also called high proof test coverage).
This webinar will show that the real objective is to detect failures NOT detected by automatic diagnostics explain proof test coverage, why this is an important safety parameter, and will explain how proof test coverage is calculated, showing several examples of proof test procedures along with the test coverage.
This subject is covered more in depth in exida’s latest publication Final Elements in Safety Instrumented Systems, IEC 61511 Compliant Systems and IEC 61508 Compliant Products.
Blog Entry: Fake Fact: IEC 61508 Does Not Affect Me As an End User
Though this is largely true, I want to discourage people from completely ignoring the good things that IEC 61508 does for the end user. IEC 61511 is the process industry functional safety standard derived from IEC 61508. In the very first section of IEC 61511 (“Scope”), the standard describes exactly…

Recorded Webinars: What’s in a Failure’s Name? Random, Systematic, or Both?
This webinar will discuss the definitions of each type of failures along with their key differences: random failures are included in probabilistic failure analysis and systematic failures require changes in operating procedures. It will look at the results of a survey where respondents classified real failures, showing that many failures classified as systematic which would result in an unrealistically low failure rate and possibly dangerous designs. We will then discuss why field failure collection systems must count all real failures until it is shown by new failure records that a change in a procedure is effective in eliminating a type of failure no matter if what it is called.
