Safety Instrumented System Compliance Case Study 3 –
Safety Instrumented System Site Testing

An existing client had recently completed commissioning of a new process plant, which incorporated several safety critical instrumented systems. The client did not have the relevant internal resource to be able to complete the periodic alarm and trip proof testing that was needed to support the safety instrumented systems’ SIL rating.

IEC generated the associated alarm and trip periodic test methods and then arranged for our compliance engineers to perform the actual tests.
