Scope
\n1.1 ISA-TR84.00.02-2002 – Part 5 is informative and does not contain any mandatory requirements.
\nISA-TR84.00.02-2002 – Part 5 is intended to be used only with a thorough understanding of ISATR84.00.02-
\n2002 – Part 1 which defines the overall scope.<\/p>\n

1.2 ISA-TR84.00.02-2002 – Part 5 provides:<\/p>\n

a) guidance in PFD analysis of logic solvers;
\nNOTE The term "logic solver" will be used throughout Part 5 to indicate the SIS logic solver. The logic solver technology may be any E\/E\/PES.
\nb) a method to determine the PFD of logic solvers;
\nc) failure rates and failure modes of logic solvers;
\nd) the impact of diagnostics, diagnostic coverage, covert faults, test intervals, common cause,
\nsystematic failures, redundancy of logic solvers on the PFD of the logic solver; and
\ne) a method for the verification of PFD of logic solvers.<\/p>\n

1.3 The procedures and examples outlined in ISA-TR84.00.02-2002 – Part 5 provide the engineer with
\nMarkov modeling steps to be followed in determining a mathematical value for the PFD for typical
\nconfigurations of SIS logic solvers designed according to ANSI\/ISA-84.01-1996.<\/p>\n

1.4 Persons using ISA-TR84.00.02-2002 – Part 5 require a basic knowledge of Markov Analysis.<\/p>\n

1.5 See ISA-TR84.00.02-2002 – Part 1 (Introduction), Part 2 (Simplified Equations), Part 3 (Fault Tree
\nAnalysis), and Part 4 (Markov Analysis) if it is necessary to mathematically evaluate the SIL of the safety
\ninstrumented function (SIF).\n <\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
