WG 3 - TC 65/SC 65E/WG 3

IEC 62382:2024 defines procedures and specifications for loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the beginning of cold commissioning. This document is applicable for the construction of new plants and for expansion or retrofits (i.e. revamping) of electrical and instrument (E&I) installations in existing plants (including PLC, DCS, panel-mounted and field instrumentation). It does not include a detailed checkout of power distribution systems, except as they relate to the loops being checked (i.e. a motor starter or a power supply to a four-wire transmitter). Loop checks can be performed throughout the lifecycle of the plant. This document is also applicable when loop checks are performed after commissioning. This document describes what is intended to be tested but not how the test is performed, due to the wide range of technologies and equipment available.
The intent of this document is to provide a means for all parties, including the owner, the installer and the vendor, to clearly establish and agree on the scope of activities and responsibilities involved in performing these tests in order to achieve a timely delivery and acceptance of the automation system. The activities described in this document can be taken as a guideline and adapted to the specific requirements of the process, plant or equipment.
This edition includes the following significant technical changes with respect to the previous edition:
a) general re-organization of the content of the previous edition, moving informative content to the annexes;
b) replacing the forms based on I/O type in IEC 62382:2012, Annex A to Annex E with an example of a generic loop check form;
c) providing additional references to other applicable standards.

IEC 62381:2024 defines requirements and checklists for the factory acceptance test (FAT), the factory integration test (FIT), the site acceptance test (SAT), and the site integration test (SIT). These tests are carried out to demonstrate that the automation system meets the requirements of the applicable specification. This document provides a means for all parties, including the owner, the buyer, and the vendor, to clearly establish and agree on the scope of activities and responsibilities involved in performing these tests in order to achieve a timely delivery and acceptance of the automation system. The activities specified in this document can be used to develop test plans adapted to the specific requirements of the process/plant/equipment. The annexes of this document contain checklists which are available for consideration when preparing specific test procedures and documentation for a specific automation system.
This edition includes the following significant technical changes with respect to the previous edition:
a) General re-organization of the standard;
b) Current technology incorporated;
c) Optional factory integration test (FIT) added;
d) Replaced the forms in the annexes with detailed checklists of activities which can be used to develop project-specific test plans; and
e) Provided additional references to other applicable standards.

IEC 62382:2012 describes the steps recommended to complete a loop check, which comprises the activities between the completion of the loop construction (including installation and point-to-point checks) and the start-up of cold commissioning. This standard is applicable for the construction of new plants and for expansion/retrofits (i.e. revamping) of E&I installations in existing plants (including PLC, BAS, DCS, panel-mounted and field instrumentation). This second edition cancels and replaces the first edition published in 2006 and constitutes a technical revision. The main changes with respect to the previous edition are: The definition of the documents mentioned in the standards is in accordance with IEC 62708: Documents for Electrical and Instrumentation Projects in the Process Industry. Subclause 6.3 has been revised.

IEC 62337:2012 defines specific phases and milestones in the commissioning of electrical, instrumentation and control systems in the process industry. By way of example, it describes activities following the "completion-of-erection" milestone of the project and prior to the "acceptance-of-the-plant" phase by the owner. Such activities need to be adapted for each type of process/plant concerned. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. The main changes with respect to the previous edition is: the definition of the documents mentioned in this standard is in accordance with future IEC 62708. The contents of the corrigendum of December 2012 have been included in this copy.

IEC 62381:2012 defines the procedures and specifications for the Factory Acceptance Test (FAT), the Site Acceptance Test (SAT), and the Site Integration Test (SIT). These tests are carried out to prove that the automation system is in accordance with the specification. The description of activities given in this standard can be taken as a guideline and adapted to the specific requirements of the process, plant or equipment. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. The main changes with respect to the previous edition are: The definition of the documents mentioned in this standard is in accordance with future IEC 62708.

IEC 62381:2006 defines procedures and specifications for the Factory Acceptance Test (FAT), the Site Acceptance Test (SAT), and the Site Integration Test (SIT). These tests are carried out to prove that the automation system is in accordance with the specification. It cancels and replaces IEC/PAS 62381 published in 2004. This first edition constitutes a technical revision. This bilingual version (2013-04) corresponds to the monolingual English version, published in 2006-11.
