Meeting Architecture Constraints in SIF Design

Recording Date: March 2013

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.
