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 61069-1 has been prepared by subcommittee 65A: System
aspects, of IEC technical committee 65: Industrial-process measurement, control and
automation.
This second edition cancels and replaces the first edition published in 1991. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Reorganization of the material of IEC 61069-1:1991 to make the overall set of standards
more organized and consistent;
b) IEC TS 62603-1:2014 has been incorporated into this edition.

INTRODUCTION
IEC 61069 deals with the method which should be used to assess system properties of a
basic control system (BCS). IEC 61069 consists of the following parts:
Part 1: Terminology and basic concepts
Part 2: Assessment methodology
Part 3: Assessment of system functionality
Part 4: Assessment of system performance
Part 5: Assessment of system dependability
Part 6: Assessment of system operability
Part 7: Assessment of system safety
Part 8: Assessment of other system properties
Assessment of a system is the judgement, based on evidence, of the suitability of the system
for a specific mission or class of missions.
To obtain total evidence would require complete evaluation (for example under all influencing
factors) of all system properties relevant to the specific mission or class of missions.
Since this is rarely practical, the rationale on which an assessment of a system should be
based is:
– the identification of the importance of each of the relevant system properties;
– the planning for evaluation of the relevant system properties with a cost-effective
dedication of effort to the various system properties.
In conducting an assessment of a system, it is crucial to bear in mind the need to gain a
maximum increase in confidence in the suitability of a system within practical cost and time
constraints.
An assessment can only be carried out if a mission has been stated (or given), or if any
mission can be hypothesized. In the absence of a mission, no assessment can be made;
however, examination of the system to gather and organize data for a later assessment done
by others is possible. In such cases, the standard can be used as a guide for planning an
evaluation and it provides methods for performing evaluations, since evaluations are an
integral part of assessment.
In preparing the assessment, it can be discovered that the definition of the system is too
narrow. For example, a facility with two or more revisions of the control systems sharing
resources, e.g., a network, should consider issues of co-existence and inter-operability. In this
case, the system to be investigated should not be limited to the “new” BCS; it should include
both. That is, it should change the boundaries of the system to include enough of the other
system to address these concerns.
The part structure and the relationship among the parts of IEC 61069 are shown in Figure 1.

INDUSTRIAL-PROCESS MEASUREMENT, CONTROL AND AUTOMATION –
EVALUATION OF SYSTEM PROPERTIES
FOR THE PURPOSE OF SYSTEM ASSESSMENT –

Part 1: Terminology and basic concepts



1 Scope
This part of IEC 61069 defines the terminology and outlines basic concepts in the assessment
of a basic process control system (BPCS) and a basic discrete control system (BDCS). These
two general system types cover the areas of discrete, batch and continuous applications. In
IEC 61069 these two, BPCS and BDCS, together are referred to as "basic control system(s)",
(BCS).
The treatment of safety in IEC 61069 is confined to hazards that can be present within the
BCS itself.
Considerations of hazards that can be introduced by the process or equipment under control,
of the BCS to be assessed, are excluded.
Where the BCS risk reduction is intended to be less than 10 (i.e. SIL < 1, per IEC 61508-4),
then assessment comes under IEC 61069.
A BCS with a safety integrity level (SIL) or performing any safety instrumented function (SIF)
is not covered by IEC 61069, where SIL is defined by IEC 61508-4 and SIF is defined by
IEC 61511-1.
This part of IEC 61069 is intended for the users and manufacturers of systems, and also for
those who are responsible for carrying out assessments as an independent party.
