Additional information for individual loop.This standard establishes minimum required information andidentifies additional optional information for a loop diagram foran individual instrumentation loop. This loop is typically part ofa process depicted on the class of engineering drawings referred toas Piping and Instrument Drawings (P&IDs).
Suitability. This standard is suitable for usein the chemical, petroleum, power generation, air conditioning,metal refining, and many other industries.
Specialty fields. Certain fields, such asastronomy, navigation, and medicine, use very specializedinstruments that are different from the conventional industrialprocess instruments. No specific effort to have this standard meetthe requirements of those fields has been made. However, thisstandard is flexible enough to meet many of the needs of specialtyfields.
Purpose
Provide guidelines. This standard will provideguidelines for the preparation and use of instrument loop diagramsin the design, construction, start-up, operation, maintenance, andmodification of instrumentation systems.
Assist understanding. This standard will assistthe understanding of instrument loop diagrams and improvecommunications among technical, non-technical, management, design,construction, operating, and maintenance personnel.
