MILESTONES AND ACTIVITIES DURING COMMISSIONING
OF ELECTRICAL INSTRUMENTATION AND CONTROL SYSTEMS
IN THE PROCESS INDUSTRY
FOREWORD
A PAS is a technical specification not fulfilling the requirements for a standard, but made available to the public.
IEC-PAS 62337 has been prepared by IEC technical committee 65: Industrial-process measurement and control.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document:
Draft PAS Report on voting
65/291/PAS 65/300/RVD
Following publication of this PAS, the technical committee or subcommittee concerned will investigate the
possibility of transforming the PAS into an International Standard.
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the
form of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
This PAS shall remain valid for no longer than 3 years starting from 2002-09. The validity may be
extended for a single 3-year period, following which it shall be revised to become another type of
normative document, or shall be withdrawn.

INTRODUCTION
There is an increasing trend in the process industry to award the construction of total plants to
contractors on a lump-sum turnkey or similar commercial basis. Experience has shown that both the
process industry (hereafter called owner) and the contractor have long and expensive discussion to
lay down unambiguously the scope of activities to be taken by the contractor and the owner and their
responsibilities to achieve the hand over of the plant.
This document should lead to an improvement and acceleration of the negotiation phase and to a
mutual understanding about the scope of activities of each party.
This document does not reflect the interests of the pharmaceutical industry or other highly specialized
industries.
MILESTONES AND ACTIVITIES DURING COMMISSIONING
OF ELECTRICAL INSTRUMENTATION AND CONTROL SYSTEMS
IN THE PROCESS INDUSTRY
1 Scope
This document defines phases and milestones (see figure 1) and describes as an example activities
after the “Completion of Erection” milestone of the project and prior to the Acceptance of Plant by the
owner. For each type of process/plant the activities shall be adapted.

NOTE Construction and Precommissioning activities could be overlapping.

2 Definitions
For the purposes of this document the following definitions apply.
2.1
precommissioning
phase, during which the activities of non-operating adjustments, cold alignment checks, cleaning, and
testing of machinery take place. Refer to Annex B for the detailed activities.
2.2
mechanical completion
milestone, which is achieved („Mechanically Complete’’) when the plant, or any part thereof, has been
erected and tested in accordance with drawings, specifications, instructions, and applicable codes and
regulations to the extent necessary to permit cold commissioning. This includes completion of all
necessary electrical and instrumentation work. This is a milestone marking the end of the
precommissioning activities.
2.3
cold commissioning
phase, during which the activities associated with the testing and operation of equipment or facilities
using test media such as water or inert substances prior to introducing any chemical in the system
take place.
2.4
start Up
milestone marking the end of Cold Commissioning. At this stage the operating range of every
instrument loops shall already be adjusted to reflect the actual working condition.

2.5
hot commissioning
phase, during which the activities associated with the testing and operation of equipment or facilities
using the actual process chemical prior to making an actual production run take place.
2.6
start of production
milestone marking the end of Hot Commissioning. At this stage the Plant is ready for full and
continuous operation.
2.7
performance test
milestone at which time the Owner’s personnel run the production plant, with the help and supervision
of the contractor, to its design capacity. This test is to demonstrate the Contractor’s Process
Performance and Consumption Guarantees as specified in the contract.
2.8
acceptance of plant
milestone in which the formal turn over of the plant from the contractor to the owner is carried out. At
this time the contractor is relieved from any obligation, with exception to defect liability and any other
outstanding obligations which are part of the contract. The owner resumes full responsibility in running
and maintaining the plant.
2.9
owner
company that hired a contractor to build a chemical plant, petrochemical plant, etc.
2.10
contractor
company which is hired by the owner to design and build a chemical plant, petrochemical plant, etc.
This company is responsible for all activities as described in a separate contract including e.g. the
engineering design, procurement, erection of the plant as well as the implementation of all tests and
acceptance that are necessary to deliver a serviceable plant. This company may also be responsible
in training the owner’s production as well as maintenance personnel on plant operation.
2.11
licenser
company or individual that has a process know how which willingly provides the owner with the
technology to be used in the construction, operation and maintenance of a chemical plant,
petrochemical plant, etc., or part of the process in such a plant.
2.12
vendor
manufacturer or distributor of a piece of equipment/instrument/package unit. The vendor should be the
expert for the proper installation as well as the operation of the equipment/instrument/package unit.
2.13
process Industry
refers to the following types of industries: chemical, petrochemical, waste treatment, paper, cement,
etc. It does not include such industries as equipment/machine manufacturing or other similar
industries and does not include pharmaceutical or other highly specialized industry.
3 Recommendations for the usage of this document
This document assumes that the “Acceptance of Plant” milestone will occur after the Performance
Test. If this is not the case, this document should be adapted accordingly.
4 General preparations before acceptance of plant
The following items shall be completed in accordance with the responsibilities as defined within the
Contract:
a) Documents
The agreed upon documents pursuant to Annex A, clause A.1 shall be issued by contractor to
owner.
b) Manpower Mobilization Plan
The agreed upon amount of manpower required both from the owner as well as from the
contractor including their qualification and their availability shall be available. The organization of
personnel during Precommissioning, Commissioning and Performance test shall be established.
c) Equipment and Tools
The agreed up
