What is Proof Testing? Why Proof Test is Important in Oil & Gas Plants?

In Safety Instrumented System (SIS) - Proof testing is very critical to ensure all SIS Sensors, the logic solver & Final control elements are functioning healthily as designed Various International Standards such as IEC, ISA & ANSI govern the requirements of SIS Proof testing. What is Proof testing? Proof testing is a test performed to reveal undetected faults in a Safety Instrumented System, so that in case of any instrument/system deterioration, the system can be restored to its designed functionality as per IEC-61511 standards. #ProofTesting #instrumentation #Instruments Tags: functional safety,exida,safety instrumented system,proof testing,proof test,functional safety engineer,proof testing machine,safety instrumented systems training,safety plc,safety plc realpars,safety plc testing,safety instrumented systems,safety integrity level,sis,iec 61511,process safety,process control,basic process control system,protection layers,sensors,logic solver,valves,shutdown valve,sis instruments,oil and gas,instrumentation training
