Evolutionary Themes from ISA 84 to ISA 61511
Abstract
ANSI/ISA 84.00.01 was the second edition of ISA standard to address safety instrumented systems for the process industry sector and was recognized by OSHA as a good engineering practice within process safety management. Nevertheless, standards must evolve over time based on application experience. After a decade of international process sector experience in applying these requirements for safety instrumented systems (SIS), a new edition of the IEC 61511 international standard was published. Recently published, ANSI/ISA 61511-1 brings the ISA standard into complete alignment with IEC 61511-1. This paper will review ten major themes of change between ANSI/ISA 84.00.01 and ANSI/ISA 61511-1.
