ISA 84.01

Purpose

This standard addresses the application of Safety Instrumented Systems (SIS) for the process industries. The SIS addressed includes Electrical (E)/, Electronic (E)/ and Programmable Electronic (PE) technology. This standard is process industry specific within the framework of the International Electrotechnical Commission (IEC) draft Publication 1508 (References C.8 and C.9). This standard follows the Safety Life Cycle presented later (see Figure 4.1).

• This document is intended for those who are involved with SIS in the areas of
• design and manufacture of SIS products, selection, and application
• installation, commissioning, and Pre-Startup Acceptance Test
• operation, maintenance, documentation, and testing
