This standard has been developed as a process sector implementation of IEC 61508.Part 2 provides guidance on the specification, design, installation, operation and maintenance of Safety Instrumented Functions and related safety instrumented system as defined in ANSI/ISA-84.00.01-2004 Part 1 (IEC 61511-1 Mod). For existing SIS designed and constructed in accordance with codes, standards, or practicesprior to the issue of this standard (e.g., ANSI/ISA-84.01-1996), the owner/operator shalldetermine that the equipment is designed, maintained, inspected, tested, and operating in a safe manner.Part 3 provides information on:– the underlying concepts of risk, the relationship of risk to safety integrity, see Clause 3;– the determination of tolerable risk, see Annex A;– a number of different methods that enable the safety integrity levels for the safety instrumented functions to be determined, see Annexes B, C, D, E, and F.In particular, Part 3:a) applies when functional safety is achieved using one or more safety instrumented functions for the protection of either personnel, the general public, or the environment;b) may be applied in non-safety applications such as asset protection;c) illustrates typical hazard and risk assessment methods that may be carried out to define the safety functional requirements and safety integrity levels of each safety instrumented function;d) illustrates techniques/measures available for determining the required safety integritylevels;e) provides a framework for establishing safety integrity levels but does not specify the safetyintegrity levels required for specific applications;f) does not give examples of determining the requirements for other methods of risk reduction.
