International Society of Automation News Release
ISA Standard on Loop Checks Approved by ANSI
Research Triangle Park, North Carolina, USA (2 August 2012)—The International Society of Automation (ISA) announced today that an ISA standard, ANSI/ISA-62382-2012 (IEC 62382 Modified), Automation Systems in the Process Industry—Electrical and Instrumentation Loop Check, has been approved by the American National Standards Institute (ANSI) and is now available.
This standard defines procedures and specifications for loop checks, which comprise the activities between the completion of the loop construction (including installation and point-to-point checks) and the start-up of cold commissioning. It is applicable to the construction of new plants and to expansion/retrofits (i.e. revamping) of E&I (electrical & instrument) installations in existing plants (including PLC, DCS, panel-mounted and field instrumentation).
The standard is a US-modified adoption by the ISA105 standards committee of IEC 62382 Edition 1. While the content is largely the same as IEC 62382, this adoption includes such changes as:
This adoption follows the adoption by ISA105 and publication in late 2011 of the following: ANSI/ISA-62381-2011 (IEC 62381 Modified), Automation Systems in the Process Industry—Factory Acceptance Test (FAT), Site Acceptance Test (SAT) and Site Integration Test (SIT).
