Safety requirements specification (SRS)
Clarifies what is in a SRS, and additions
. E.g.:
–
Defining the safe state for a stable state achieved
.
–
Defining that the response time to bring the
process to a safe state is < the process safety time.
–
Written procedures to be applied during bypassing
.
Allows the Application Program (AP) safety
requirements to be in the SRS, or in a
separate document (e.g., APRS)
.
If separate APRS it shall be similar to SIS
SRS.
