A formal specification defining the safety functions and performance requirements necessary to achieve functional safety objectives.
A Safety Requirements Specification (SRS) is a controlled engineering document that defines the functional, performance and integrity requirements for safety-related systems, including Safety Instrumented Functions (SIFs). The SRS establishes the technical basis for the design, implementation, verification, operation and maintenance of Safety Instrumented Systems throughout their lifecycle.
Safety Requirements Specifications define the functional and performance requirements necessary to achieve and maintain functional safety.
The Safety Requirements Specification is a key lifecycle deliverable within IEC 61508 and IEC 61511 and provides the technical foundation for designing and validating Safety Instrumented Systems.
A Safety Requirements Specification defines the required performance of safety functions, whereas a Safety Instrumented System implements those requirements through hardware and software.
