Safety Requirement Specification (SRS)

The Safety Requirement Specification (SRS) (clause 10 of ISA/IEC 61511) takes the results of the hazard and risk assessments and defines the requirements of the Safety Instrumented Functions (SIFs) that have to be performed by the Safety Instrumented Systems (SIS).

aeSolutions is qualified with Certified Functional Safety Experts to quantify process hazard risks and develop the Safety Requirement Specification (SRS) for a process. The SRS is an input to the SIS design process but not all of the required information is available when design starts. Our SIS Specialists have configuration, instrumentation, and operations experience, allowing them specify feasible solutions to complex SIF implementation problems.
