Abstract: According to IEC 65111 and IEC 65108 standards and the characteristics of petrochemical refining and chemical enterprises, this paper makes a demonstrative evaluation on the relevant safety instrumented systems, the newer instruments that have been certified by third parties. The evaluation work mainly includes the establishment and management of relevant safety instrument functions and verification of the functions. It also proposes the requirements that need to be supplemented in the safety instrument management of petrochemical enterprises.

Key words: safety instrument system/SIS, safety integrity level, safety instrumented function/SIF, hazard and operability study/HAZOP, layer of protection analysis/LOPA
