The life cycle of safety instrumented systems (SIS) —specification, design, analysis, programming, installation, maintenance and change management — is the focus of a new book from the International Society of Automation (ISA).

“Safety Instrumented Systems: A Life-Cycle Approach” leverages the performance and documentation requirements defined in the ISA/IEC 61511 functional process safety standard along with the authors’ nearly 80 years of safety system experience and insights. The book, in addition to explaining the significance and value of the ISA/IEC 61511 standard in improving functional process safety, provides important practical guidance and real-world case studies.
