Scope

1.1 ISA-TR84.00.02-2002 - Part 4 is informative and does not contain any mandatory requirements.ISA-TR84.00.02-2002 - Part 4 is intended to be used only after a thorough understanding of ISATR84.00.02-2002 ? Part 1. This technical report is intended to provide

a) technical guidance in Safety Integrity Level (SIL) Analysis;
b) ways to implement Safety Instrumented Functions (SIF) to achieve a specified SIL;
c) failure rates and failure modes of SIF components;
d) diagnostics, diagnostic coverage, covert faults, test intervals, redundancy of SIF components; and
e) tool(s) for SIL verification of SIF.

1.2 ISA-TR84.00.02-2002 - Part 4 provides one possible technique for calculating PFDavg values forSafety Instrumented Systems (SIS) installed in accordance with ANSI/ISA-84.01-1996, "Application ofSafety Instrumented Systems for the Process Industries.?

1.3 Persons using ISA-TR84.00.02-2002 - Part 4 require knowledge of the Markov modeling technique.The reader who is interested in learning more about Markov modeling is referred to:

- Evaluating Control Systems Reliability(5), Chapter 5;
- Reliability Evaluation of Engineering Systems(12), Chapter 8 and 9;
- Introduction to Reliability Engineering(13), Chapter 9;
- ISA-TR84.00.02-2002 - Part 5.
1.4 ISA-TR84.00.02-2002 - Part 4 introduces the reader to three examples, which explain the Markovtheory and capabilities. These three examples make it possible to better understand the Base Example,which is also presented in ISA-TR84.00.02-2002 ? Part 2 and ISA-TR84.00.02-2002 ? Part 3.
