Blog Entry: The exida Certificate Explained
A manufacturer whose product passes the exida IEC 61508 Assessment Scheme will receive a certificate based on IEC 61508 and perhaps other functional safety standards. There is a significant amount of information on a certificate that may not be always trivial for a novice. This document explains how one should…
Recorded Webinars: Comparing Failure Rate Data
This webinar will show the results of a set of recent failure rate data comparisons between exida FMEDA results and field failure data from the process industries. A number of different categories of comparisons were done, including transmitters, valves, actuators, and solenoid valves. Results from DOW and OREDA are directly compared against FMEDA results.
It is essential that any predictive failure technique like FMEDA be calibrated via actual field failure results. The technique used by exida to accomplish this calibration will be described along with examples of lessons learned after ten years of comparisons.
This webinar will help any engineer doing SIF verification calculations to understand how to pick failure rate data.
Blog Entry: How Good Is Your Functional Safety Management?
Those operating in the process world should be familiar with the concept of Functional Safety Management (FSM) and the need to have well defined processes and procedures in place. Otherwise, how else will they be able to ensure that their Safety Instrumented System 〈SIS〉 and plant are operating safely? Functional…
White Paper: Functional Safety and EMI
Electromagnetic Interference (EMI) is just one of the environmental stresses that can stop a system from performing its safety function. It is important for a functional safety system to be immune from the EMI levels that are likely to be present. Unlike other environmental stresses, like temperature and vibration, EMI…
Blog Entry: Functional Safety And Electromagnetic Interference: What’s the Connection?
Functional Safety and Electromagnetic Interference (EMI) may not often be used in the same sentence. But EMI is just one of the environmental stresses that can stop a system from performing its safety function. It is important for a functional safety system to be immune from the EMI levels that…
Recorded Webinars: An Introduction to Universal Modeling Language (UML)
Universal Modeling Language (UML) is a popular modeling notation used to specify functional requirements, architectural design, detailed design and can even be used to generate executable software. IEC 61508 semi-formal methods, computer-aided specification and design tools, and model-based requirements can be addressed by UML notation and the tools that support it. This brief (1½ hour) introduction covers the basic notation and diagrams used in modeling.

Recorded Webinars: How are You Handling the O & M Requirements of IEC 61511?
It is hard to believe that the IEC 61511 standard has been in existence since 2003 and most companies operating in the process, chemical, and refining industries, (or any other hazardous process manufacturer) have adopted its practices. It is also significant that any plants that were built at that time with a Safety Instrumented System (SIS) will now be halfway through their useful life. This begs the question of how well have companies been recording the performance of their SIS systems, in terms of failures, spurious trips, and proof testing results? This webinar highlights how testing and documenting the performance of the SIS is an essential part of ensuring that the SIS is able to fulfill its designed functional safety requirements. This is especially true as the SIS approaches its end of useful life.

Blog Entry: Stress vs. Strength… In My Process?
I consistently find that with companies who are new to functional safety development, the SW process is not as structured or mature as the HW process. SW development is often more informal, and subject to the interpretation of one or more SW developers. But when project delays occur, it’s usually…
Recorded Webinars: Gas Detection and Safety Instrumented Systems
Many critical functions rely on effective gas monitoring and detection. When the functions are part of safety instrumented systems, additional requirements apply for the process owners and equipment suppliers. This webinar will review some of the key considerations that must be addressed when designing systems for safety applications. Topics to be covered include:
- Requirements for SIF design utilizing gas detection
- Typical gas detection SIFs
- Market and compliance requirements for manufacturers of gas detection sensors
- Product certification strategies
Who should attend:
- Gas detection and monitoring OEMs
- Safety Engineers
- Corporate Compliance Engineers and Managers
Blog Entry: World Cup Fever & Failure Rates
Do you have World Cup Fever? Well I do. Especially after the Netherlands (Holland) beat Spain 5-1 on Friday. I wished that was the score last time they played. So what does this have to do with failure rates? Sometimes my mind works in odd ways. While driving home from…
