ELECTRICAL AND INSTRUMENTATION LOOP CHECK

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62382 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.
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 listed below:
– 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.
The text of this standard is based on the following documents:

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a

INTRODUCTION
The inspection and verification of the individual measurements and controls in conjunction
with the control systems used to monitor these devices (DCS, PLC, etc.) is referred to as loop
check. In industry, numerous methods and philosophies are used to check the instrumentation
and controls after mechanical installation within projects for modified or new facilities.
This standard was created to provide a better understanding of what loop check consists of
and also to provide a standard methodology for executing a loop check.
The annexes of this standard contain forms which may be used in the check procedures.
Buyers of this standard may copy these forms for their own purposes only in the required
amount.

CONTROL SYSTEMS IN THE PROCESS INDUSTRY –
ELECTRICAL AND INSTRUMENTATION LOOP CHECK

1 Scope
This International Standard 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). 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).
For application in the pharmaceutical or other highly specialized industries, additional
guidelines (for example, Good Automated Manufacturing Practice (GAMP)), definitions and
stipulations should apply in accordance with existing standards, for example, for GMP
Compliance 21 CFR (FDA) and the Standard Operating Procedure of the European Medicines
Agency (SOP/INSP/2003).

4 Order of loop check and cold commissioning in the project schedule
The loop checks will ideally occur in the precommissioning phase of the schedule shown in
Figure 1.
62382 © IEC:2012 – 9 –
However, normal occurrence is that the loop checks begin when any specific loop is
completed and turned over to the checkout crew even if it is during the "construction" phase.
The loop check could substantially overlap the "construction" phase.

Figure 1 – Definition of phases and milestones
The loop check has the following characteristics:
• it follows the E&I construction phase and FAT of the DCS in a project;
• it is the last systematic check before mechanical completion to ensure that:
• all E&I documents (loop sheets, etc.) are available and correspond to their latest revision;
• all instrumentation and equipment is delivered according to the design specifications if not
already verified during FAT or quality check during equipment receiving;
• installation has occurred in accordance to engineering documents, applicable codes and
local regulations;
• loop functionality is correct.
This provides that:
• in a project, the quality check for E&I engineering, and for the delivered instrumentation
and equipment and their installation;
• the base for the commissioning phase which consists of the following phases:
