Full Description<\/b><\/p>\n

\n
\n1 Scope<\/p>\n

1.1 ISA-TR84.00.02-2002 – Part 1 is informative and does not contain any mandatory clauses. ISATR84.00.02-
\n2002 is intended to be used only with a thorough understanding of ANSI\/ISA-84.01-1996
\n(see Figure I.1). Prior to proceeding with use of ISA-TR84.00.02-2002 in a safety application, the
\nHazards and Risk Analysis must have been completed and the following information provided<\/p>\n

a) It is determined that a SIS is required.
\nb) Each safety instrumented function to be carried out by the SIS(s) is defined.
\nc) The SIL for each safety instrumented function is defined.<\/p>\n

1.2 ISA-TR84.00.02-2002 – Part 1 provides<\/p>\n

a) guidance in Safety Integrity Level analysis;
\nb) methods to implement Safety Instrumented Functions (SIF) to achieve a specified SIL;
\nc) discussion of failure rates and failure modes (Annex D) of SIS and their components;
\nd) discussion of diagnostic coverage, covert faults, common cause, systematic failures, redundancy of
\nSIF;
\ne) tool(s) for verification of SIL; and
\nf) discussion of the effect of functional test interval.<\/p>\n

1.3 The objective of ISA-TR84.00.02-2002 – Part 1 is to introduce the reader to the performance based
\napproach for evaluating the reliability of SIF and to present system reliability methodologies that can be
\nused to evaluate the system performance parameters, namely, the probability that the SIF fails to respond
\nto a demand and the probability that the SIF creates a nuisance trip. ISA-TR84.00.02-2002 – Part 1
\nserves as an introduction for all other parts.\n <\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
