Guidance for Testing of Process Sector Safety Instrumented Functions (SIF) Implemented as or within Safety Instrumented Systems
Provides guidance on performing testing of SIF components and systems to achieve full safety benefits of the SIF in the most cost-effective way. Presents both manual and automated techniques for off-line and on-line testing of SIF, including existing and proposed techniques, and describes the benefits of each technique. Prepares users to meet the testing requirements of ANSI/ISA-84.01-1996 and IEC 61511 by utilizing the techniques described in conjunction with and overall safety management program. Describes techniques for testing all elements of the SIF including field sensors, final control elements, logic solvers (signal conversion modules included), Human Machine Interface (HMI), communication links with other systems, user application software, and other required auxiliaries such as power. Presents suggested inspection techniques for regular observation of equipment and components to detect potential problems. The techniques described can also be used for testing burner management systems in conjunction with the NFPA 85 code.
