IEC 61511 was developed as a process sector-specific implementation of IEC 61508, focusing on two core concepts: the safety lifecycle and safety integrity levels (SIL). The safety lifecycle serves as the foundation, connecting key elements throughout the standard to guide the design and implementation of safety-instrumented systems (SIS). This structured engineering approach ensures that process risks are thoroughly evaluated, and performance requirements for SIS-such as availability and risk reduction-are clearly established. Implementing the safety lifecycle is essential for achieving consistent, reliable SIS designs and safeguarding operational integrity. #SIS #SIL #Safety #Instrumentation #Process

What is "Safety Manual" in context to SIF elements (sensors, logic solvers & final elements) & how it is important in context to Functional Safety Lifecycle: Both IEC61511 & IEC61508 (International Standard for Safety Instrumented System) enforces requirement of safety manuals to OEMs/Vendors of safety related equipment which as a minimum shall contain following safety critical data required to ensured SIF reliability calculation: - Classification of devices/instrument i.e. Type-A or Type-B (as per IEC) - Failure data including λSd, λSu, λDd & λDu (safe detected, safe undetected, dangerous detected & dangerous undetected respectively) - Most importantly declaration of "Systematic Safety Integrity i.e. Systematic Capability (SC); it means if we are aiming for SIL3 classified SIF then respective product manufacturer's "Functional Safety Management" must be matured enough for SIL3. Many times "Safety Manual" requirement is overlooked during start of the project OR during realization phase functional safety loop which is one the biggest gap. Hence being end-user always ask for Safety Manual when having technical bid evaluations and ordering safety related equipment/devices. Well established manufacturers having robust FSM in place have following information in safety manual as per below screenshot. This document not only helps to perform SIF reliability calculation but also helps to develop proof test/partial proof test procedure for safety lifecycle. This is why during start of any project/development of Functional Safety Management plan - "Safety Requirement Specification (SRS)" defining these requirements is must needed deliverable from end-user/EPCs to respective OEM/Vendor.

Process Industries rely upon the performance of Safety Instrumented Functions (SIFs) to protect and maintain operating assets. Engineers and designers are required to verify if the designed process is safe, and the SIFs meet the requirements for their SIL. #TUV’s Design SIL Achievement training course has been designed for those delegates that require more detailed training in the concepts and principles that underpin the IEC 61511 functional safety standard and its use for verifying the Safety Integrity Level of a proposed or existing safety instrumented function. Join me, on the Design SIL Achievement training course and on completion you will: - Understand the concepts underpinning SIL achievement requirements - Identify what information is essential before starting the calculation - Apply correct formula PDFavg / PFH for serial or parallel instrument configurations - Derive instrument failure rates from commonly available sources - The benefits and disadvantages of manufacturers certificates - What checking and approval is needed for different Safety Integrity Levels - Verify the achieved SIL from a number of worked examples 📅Date: 3rd & 4th September 2024 🏢Location: TUV Offices, Billingham,Teesside #SIL #IEC61511 #processsafety #functionalsafety

Your Equipment SIL Level is Virtual Without Testing: The Effect of Imperfect Proof Test SIL is a measure of the amount of “risk reduction” provided by a Safety Instrumented Function. Each SIL level provides a one order of magnitude decrease in the frequency of the event. As per IEC 61511, a Safety Function should prevent a specific hazardous event. A safety Instrumented Function (SIF) is derived from the Safety Function which has an associated safety Integrity Level (SIL) and carried out by a specific safety Instrumented System (SIS). For Each Safety Function we need to know how often it fails. The probability of failure danger (PFDavg or PFH) is the probability that the safety function does not work upon demand from the process. Let us think on the “Failure” with respect to Functional Safety; -         Safe Failure: the element fails safe, if it carries out the safety function without a demand from the process. -         Dangerous Failure: the element fails danger, if it cannot carry out the safety function upon demand. -         Detected Failure: a failure is detected if built-in diagnostics reveals the failure. -         Undetected Failure: a failure that may be left unrevealed until a demand is placed upon it. -          Revealing Failures: Failures can be revealed in three ways; -         Through normal operation (Bad Thing, From a Safety point of view and also from Process Availability point of view.) -         Through built-in diagnostic tests (online, automatic) -         Through periodic proof tests (offline, initiated by human action) Over time the impact of imperfect proof testing will result in a gradual increase of PFD which may eventually lead to system not meeting the PFD requirements and reaching unacceptable level. So, now your Safety Instrumented Function (SIF) without testing becomes “Under Specified SIF” with Not enough risk reduction. #riskmanagement #processsafety #functionalsafety #SIS #SIL #integrity #maintenance #reliability

#Significance of "C" Factor in Studying Short Circuit Current in ETAP #Typically, the C factor is employed in symmetrical component analysis, which breaks down the system into positive, negative, and zero sequence components in order to examine how the system behaves when there is a failure. It is used to determine the fault currents at various locations in the system by using the right C factors for each sequence component. #ETAP #Device_Duty IEC 60909 #3Phase_Short_Circuit_Current IEC 60909 #Symmetrical_Component
