COMMISSIONING OF ELECTRICAL, INSTRUMENTATION
AND CONTROL SYSTEMS IN THE PROCESS INDUSTRY –
SPECIFIC PHASES AND MILESTONES

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 62337 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:

INTRODUCTION
There is an increasing trend in the process industry to award the construction of whole plants
to contractors on a lump-sum turnkey or similar commercial basis. Experience has shown that
both the process industry (hereinafter called “the owner”) and the contractor have long and
expensive discussions to lay down unambiguously the scope of activities to be taken by the
contractor and the owner and their responsibilities to achieve the handover of the plant.
This standard is intended to lead to an improvement and acceleration of the negotiation phase
and to a mutual understanding about the scope of the activities of each party.

COMMISSIONING OF ELECTRICAL, INSTRUMENTATION
AND CONTROL SYSTEMS IN THE PROCESS INDUSTRY –
SPECIFIC PHASES AND MILESTONES



1 Scope
This International Standard defines specific phases and milestones (see Figure 1) 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.
NOTE This standard assumes that the “acceptance-of-the-plant” milestone will occur after the performance test. If
there is a reduced scope, this document should be adapted accordingly.

NOTE Construction and precommissioning activities could be overlapping.

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).
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and

– date and time of test or check;
– identification of equipment and facilities;
– test pressure if applicable, test data and results, including remarks, if any;
– signature of the owner’s personnel witnessing the data recorded, if required.
b) Check, test and records thereof shall be carried out by the contractor’s personnel.
Wherever the owner’s witness or attesting for the check or test is required, the owner’s
personnel shall attend such check and test. For this purpose, the contractor shall keep the
owner informed of the day-to-day test-plan schedule. The test-plan schedule should be
constantly revised to reflect the actual progress of the work and test.
c) Any items found incomplete or requiring repair or adjustment shall be marked as such on a
separate punch list and reported by the contractor to the owner’s and the contractor’s
personnel in charge of the relevant construction area. The check list for items in the punch
list will be left blank until the problem has been corrected.
d) The contractor shall expedite and follow up the termination of all incomplete, repaired or
adjusted work items in the punch list and shall keep these expediting records up to date.
e) Checking procedures shall be repeated until all the items on the check list are cleared.
f) At the completion of each test, the owner shall certify on the test reports that the test has
been satisfactory; otherwise, t
