IEC 61511 and Failure Rates

Recording Date: August 2020

This webinar will help in understanding the changes to IEC61511 2016 regarding failure rates for use in the reliability calculations (i.e. PFDavg or PFH) of random failures for SIF equipment. Some certification agencies have been issuing certificates for equipment with extremely low failure rates, when compared to industry databases. This can lead to optimistically and dangerously low estimates of PFDavg/PFH for SIF equipment. The webinar will identify how to look at these failure rates and to make a quick judgement on whether they meet the requirements of IEC61511.

What you will learn:

  • How to identify bad failure rates
  • What to look for on certificates
  • Where to be able to compare certificates

Who should attend:

  • Engineering companies
  • End Users
  • Supervisors & Managers
