FOR AUTOMATION SYSTEMS IN THE PROCESS INDUSTRY

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
A PAS is a technical specification not fulfilling the requirements for a standard but made available to
the public.
IEC-PAS 62381 has been processed by IEC technical committee 65: Industrial-process measurement
and control.
The text of this PAS is based on the This PAS was approved for publication
following document: by the P-members of the committee
concerned as indicated in the following
document
Draft PAS Report on voting
65/309/PAS 65/322/RVD
Following publication of this PAS, which is a pre-standard publication, the technical committee or
subcommittee concerned will transform it into an International Standard.

INTRODUCTION
There is an increasing trend in the process industry to shorten the time period for project execution. At

the same time, the complexity of automation systems is being increased due to the number of

connected systems and the use of new technologies, for example, fieldbus systems.

Experience has shown that the owner, the contractor and the vendor have long and extensive

discussions to unambiguously lay down the scope of activities and responsibilities in order to achieve
a timely delivery and acceptance of automation systems.

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 additional interests of industries which are subject to special
requirements such as validation.
The annexes of this standard contain forms which may be used in the test procedures. They are
attached to this publication in Excel format. Buyers of this publication may copy these forms for their
own purposes only in the required amount.
The IEC sells read-only PDF files as a general rule. In the present instance, and quite exceptionally,
to enable the user to fill in the forms, a revisable file is included in a pocket affixed to the back cover of
this publication. Please use the zip/unzip function.
This file can also be downloaded from the Web as a PDF file.
