ISA-18

Standards and Technical Reports

ISA-18.1-1979 (R2004), Annunciator Sequences and Specifications. This standard is primarily for use with electrical annunciators that call attention to abnormal process conditions by the use of individual illuminated visual displays and audible devices. Annunciators can range from a single annunciator cabinet, to complex annunciator systems with many lamp cabinets and remote logic cabinets. The sequence designations provided can be used to describe basic annunciator sequences and also many sequence variations.

ANSI/ISA-18.2-2009, Management of Alarm Systems in the Process Industries. This standard provides requirements and recomendations for the activities of the alarm management lifecyle. Lifecycle stages include philosophy, identification, rationalization, detail design, implementation, operation, maintenance, monitoring & assessment, management of change, and audit.

ISA-TR18.2.4-2012, Enhanced and Advanced Alarm Methods. This technical report provides guidance on enhanced and advanced alarm methods and focuses on the scope of Clause 12 of ISA-18.2. Enhanced alarm design covers guidance on additional logic, programming, or modeling used to modify alarm behavior. These methods may include: dynamic alarming, state-based alarming, adaptive alarms, logic-based alarming, and predictive alarming, as well as most of the designed suppression methods.

ISA-TR18.2.5-2012, Alarm System Monitoring, Assessment, and Auditing. This technical report provides guidance on monitoring, assessment and audit of alarms. TR5 focuses on the scope of ANSI/ISA-18.02-2009 Clauses 16 and 18. Monitoring, assessment, and audit cover the continuous monitoring, periodic performance assessment, and recurring audit of the alarm system.

ISA-TR18.2.6-2012, Alarm Systems for Batch and Discrete Processes. This technical report covers the application of alarm management principles in ISA-18.2 to batch and discrete processes. The general principles and techniques are intended for use in the lifecycle management of an alarm system based on programmable electronic controller and computer-based human machine interface (HMI) technology.
