SIL CALCULATION EXAMPLES

[@ajigeorge6374]

Hello, check the calculation of 1oo1 configuration. please note that PFD avg formula = Lamda [DU] x Ti/2 . but please note that T/2 is not used in the calculation at timing of the video [12:07]. only the Lamda x 8760. NOT DIVIDED by 2.

Could you explain please why the motor starter is not included in the example at 10:30? You have 6.82 FIT for the safety relay. What would you suggest for the motor starter itself? I'm wondering whether you might ne relying on diagnostics and/or fault exclusion techniques.

Really very good explaniation ! thanks a lot ! only one question I have. I will be appreciate if someone can answer, This SIL Loop calculation should be done after procurement of instrument valve and control system according manufacture certificate value . isnt it ?

[@KonradT4]

IEC 61511 requires that uncertainty in reliability data shall be taken into account in the calculations. How do you determine uncertainty intervals and how do you include them in your calculations?

0.488x10^-3 less than 0.001 then it is SIL 3 not SIL 2
