What Architectural Constraints Does My Device Meet, and What Does it Mean?

Recording Date: January 2016

This webinar will discuss what an architectural constraint is, how it is determined, what architectural constraint is met, and what other factors go into a SIL requirement and the certification. Minimum architecture requirements were defined in IEC 61508 in 2000. 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.
