IEC 61511 – Proof Test Planning, Data Collection, And Analysis Apr 2012

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.
