Webinar: Proof Testing of Safety Instrumented Functions

Webinar: Proof Testing of Safety Instrumented Functions
  • Date From 7th May 2021
  • Date To 7th May 2021
  • Price Free of charge, open to all.
  • Location Online: 09:00 BST. Duration: 1 hour.

Overview

A key part of any IEC 61511 or IEC 61508 Safety Integrity Level (SIL) Assessment is the Random Hardware Failures verification; does the Safety Instrument Function (SIF) meet its Probability of Failure on Demand (PFD). Achieving this is heavily dependent on the frequency at which a SIF (and its constituent elements) is PROOF TESTED. This means that if the proof testing strategy (frequency, coverage, management etc.) is flawed, risk targets may not be met, despite ‘what the numbers say’. Clearly a good understanding of the principles of proof testing is essential. This webinar will cover:

  • main concepts and definitions
  • overview of IEC 61511 requirements
  • proof testing principles
  • practical issues
  • resource implications
  • proof test procedures
  • worked examples.

This webinar is aimed at plant managers; engineers of various engineering disciplines; safety managers and technicians.
