Latest White Paper: https://lnkd.in/eGcWMrQh The goal of performing a failure modes, effects, and diagnostics analysis (FMEDA) is to obtain important reliability and Safety metrics including: the failure rates per failure mode,  automatic diagnostic effectiveness, useful life,  and latent fault test (proof test) effectiveness of a device. This information is used for many reasons including identification of weak areas in a design, warranty cost prediction, etc. But perhaps most importantly, FMEDA results are used to calculate the safety integrity of equipment designed for automatic protection purposes (often called safety instrumented systems - SIS). These safety integrity metrics are an essential part of functional safety certification.  As valuable as the FMEDA results are, many find that the engineering time needed to perform a quality FMEDA is excessive. How can we do better? There are several techniques that are used by top FMEDA professionals to not only reduce engineering hours but increase analysis quality. One of the most effective techniques is to organize the FMEDA input information into functional blocks, with functions and failure modes for each block documented. At first glance, the introduction of functional block information seems to add complexity without clarity. However, the advantages of doing this before starting the FMEDA analysis significantly outweigh the up-front effort. This paper describes the Functional Failure Mode FMEDA process.  #exida #whitepaper #functionalsafety #FMEDA #failuremode

Registration is now open! 1-Day Training Class focused on key concepts, questions, and strategy for taking the Certified Functional Safety Professional (CFSP) exam in Process Safety. The course will be split into two ½ day (4 hour) sessions. This assumes the participants have either completed exida’s FSE100 training course or is experienced in the Functional Safety Field.  While the course will revisit the basic Functional Safety Concepts, they will be covered quickly and with minimal emphasis on the history, derivation or supporting criteria. Led by Dr. Steve Gandy Register Today:

Registration Now Open: This short course provides an overview of the IEC 62443 series of standards including the information that product marketing, sales, and senior leadership needs to know about these standards. In addition, the course talks about marketing strategies for getting out the word to your customers that your products or processes have been certified to this standard.  Course Length:  This course will run as online-live/instructor led August 21, 2024 This course is tentatively scheduled to run 9:00am-12:00pm EST Register Today:

Latest blog: https://lnkd.in/eq_pW_2T I had an engineer from a European Certification Body ask me why exida would bother paying any attention to these failure rate numbers, especially on mechanical devices? He said that he does not know anyone who actually uses them! To answer why exida pays attention to failure rates, we must ask what are we trying to accomplish by using probabilistic analysis to evaluate risk reduction provided by any automatic protection function. Why does IEC 61508 define the need for probability of dangerous failures? #exida #blog #IEC #IEC61508 #functionalsafety

Latest white paper: https://lnkd.in/eafx-4yD Remote actuated valve assemblies (RAVA) are a frequently used final element of safety instrumented functions (SIF) in the process industry.  Studies of field failure data at exida has shown potentially dangerous failures of these valve assemblies significantly depend on how they are used – the application. #exida #whitepaper #functionalsafety #RAVA #IEC #IEC61511 #IEC61508 #SIF #processindustry

Red Hat, Inc., the world's leading provider of open source solutions, today announced that the Linux math library (libm.so glibc), a fundamental component of Red Hat In-Vehicle Operating System, has achieved ISO 26262 ASIL-B functional safety certification from exida, a global leader in functional safety and cybersecurity certification. Red Hat is fully committed to attaining continuous and comprehensive safety certification of Linux natively for automotive applications and has the industry's largest pool of Linux maintainers and contributors committed to this initiative. This milestone underscores Red Hat's pioneering role in obtaining continuous and comprehensive Safety Element out of Context (SEooC) certification for Linux in automotive. #exida #redhat #ISO26262 #functionalsafety #ISO #automotive #linux https://lnkd.in/d5Jtnev2

Latest blog: https://lnkd.in/e7yJMYr6 The C programming language has undoubtably extremely successful. It consistently ranks highly in the various rankings of most popular programming languages however these studies seem to be measured. C is not a language that is naturally suited to having safety requirements given to it. So, unsuited is it to safety that the basic safety publication does not recommend C for any integrity level. Using C safely is not a task for the timorous or the brash software engineer. It took fully a quarter of a century before guidelines were first published by MISRA with "assistance to the automotive industry in the creation and application within a vehicle system of safe, reliable software." At that time the language, the hardware and the compilers were essentially all new. People not unlike yourself were using and learning through using and more than likely learning from recovering from complex mistakes. Fully one third of the MISRA C rules are guidance relevant only if the compiler does something the developer does not understand or expect. In fact, the frustration people new to MISRA C find is because the behavior of their compiler is in fact a mystery to them, and they have experience of at most two compilers. #exida #blog #functionalsafety #MISRA #ISO #ISO26262 #C #C++

Join us Live Online July 22-25 for our FSE 100 IEC 61511: Functional Safety Analysis, Design, and Operation course. Looking to become a CFSE or CFSP? This is the course you'll need to pass the exam. Also known as FSE 100, this course provides an overview of process industry safety engineering from the point of view of the Risk Analyst, Process Safety Coordinator, and Control Systems Design Engineer. It delivers a complete overview of the functional safety lifecycle. The course reviews Process Hazard Analysis (PHA), Consequence Analysis, Layer of Protection Analysis (LOPA), Safety Integrity Level (SIL) Target Selection, Safety Requirements Specification (SRS) generation, failure rates, device and system reliability, SIF verification, SIF detailed design and Operations requirements. This course forms a broad review in preparation for the Certified Functional Safety Expert (CFSE) and Certified Functional Safety Professional (CFSP) process industry application engineering exams. #exida #training #functionalsafety #CFSE #CFSP #IEC #IEC61511

We will be at stand V16 next week in Dublin. If you are at the show, stop by and say hello!

This course is now GURANTEED TO RUN! Seats still available for this offering of FSE 100!
