Recorded Webinars: IEC 61511 - Proof Test Planning, Data Collection, and Analysis
Equipment failures that would prevent an automatic safety function from performing a trip are called “dangerous failures.” These failures not detected by automatic diagnostics are only detected during a manual proof test. Making this manual testing very critical to the ongoing safety. This web seminar covers manual proof test planning and the important proof test quality metric called “proof test coverage.” The necessary procedures for recording the results of such testing are described. The methods used to analyze this data to confirm Prior Use justifications and failure data are described including the Predictive Analytic techniques used by exida.

Recorded Webinars: Accurate Failure Data – Field Calibrated FMEDA Results
While most agree that the FMEDA method provides very accurate diagnostic measurements, it is understood that overall results depend on a good component failure database that matches the application environment. A database calibrated and compared to well analyzed field failure data offers high accuracy, perhaps the best. The web seminar describes the FMEDA technique. This web seminar also then describes Predictive Analytics, a field failure analysis technique that utilizes known design information to verify quality of the data. The results from over ten billion unit operating hours of field failure studies are compared with FMEDA results. The resulting improvements to both the component database and the field failure data collection systems are covered.
Recorded Webinars: SIF Verification – Scaling the Three Barriers
This web seminar will describe the SIF verification process and three “barriers” that must be met to show that a specific design has met performance requirements for a given SIL. It will also describe the SIF Verification CFSE Endorsement requirements and is excellent preparation in part for this highly valued functional safety recognition.
Recorded Webinars: IEC 61508 (2010): What’s New and How Does it Affect Me
The IEC released their second edition of the umbrella standard for Functional Safety, IEC 61508 in 2010, which is applicable to programmable electronic safety related systems. This webinar will discuss:
• What has changed in the standard compared to first edition (2000)
• How it will impact the market for functional safety including suppliers, product developers, and end users

Recorded Webinars: Meeting Architecture Constraints in SIF Design
Minimum architecture requirements were defined in IEC 61508 in 2000. For the process industries, these requirements were “simplified” for IEC 61511 and a new optional table was added for “Prior Use” elements. The 2010 edition of IEC 61508 has retained the existing requirements, now called Route 1H, and added a new alternative set of requirements for elements with “90% confidence” in failure data and failure modes. This web seminar will review the alternative architecture constraint requirements including the new Route 2H and show one method that exida is using to claim 90% confidence in the failure rate and failure mode data.
Recorded Webinars: Final Elements and the IEC 61508 Certification
Final Elements and the IEC 61508 Certification
Attendees of the webinar will:
• Learn how IEC 61511 impacts turbine safety systems
• Develop an understanding of how implementing IEC 61511 can be used to show compliance with safety regulations
• Examine strategies to effectively implement the requirements of the standard
Recorded Webinars: Improving Reliability and Safety Performance of Solenoid Valves by Stroke Testing
Solenoid valves integrated into the design of emergency shutdown valves (ESD) used in industrial process systems, can tend to bind, i.e., to become stuck in one position, when not moved for long periods of time. This binding, also known as failure due to excessive stiction, has significant negative impacts on the valve’s reliability and safety performance. It is a serious and costly problem normally addressed by expensive and time-consuming proof tests which typically have required a process shutdown to perform testing. This webinar will describe an effective, alternative in-service testing protocol, known as valve stroke testing, which verifies whether or not the solenoid valve is stuck in position. Best practice procedure for implementing the valve stroke test will also be described, and a quantitative example of how valve stroke testing significantly improves safety performance will be provided.
Recorded Webinars: Applying IEC 61511 to Industrial Turbines: A Case Study
Turbines and their associated equipment have long been a focus of safety and safety protection functions driven by the risks to personnel and damage to equipment. Now the international safety standards are being applied in addition to local standards and requirements. Meeting IEC 61511 requires a new perspective on turbine safety systems and presents both challenges and opportunities for turbine owners. This webinar provides a review of the IEC 61511 standard and highlights its impact on turbine safety systems.
Attendees of the webinar will:
• Learn how IEC 61511 impacts turbine safety systems
• Develop an understanding of how implementing IEC 61511 can be used to show compliance with safety regulations
• Examine strategies to effectively implement the requirements of the standard
Recorded Webinars: Functional Safety: An IEC 61508 SIL 3 Compliant Development Process
This webinar provides developers of safety application products with an overview of how to implement a development process that meets the requirements of Safety Integrity Level (SIL) 3 of the IEC 61508 standard. It will illuminate and interpret the requirements of the standard, including the 2010 version, so that organizations can adapt their existing processes to comply with the standard. Material will be taken from the book of the same name, as presented by the author.
