60 FOREWORD
61 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
62 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
63 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
64 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
65 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
66 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
67 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
68 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
69 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
70 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
71 consensus of opinion on the relevant subjects since each technical committee has representation from all
72 interested IEC National Committees.
73 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
74 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
75 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
76 misinterpretation by any end user.
77 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
78 transparently to the maximum extent possible in their national and regional publications. Any divergence between
79 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
80 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
81 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
82 services carried out by independent certification bodies.
83 6) All users should ensure that they have the latest edition of this publication.
84 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
85 members of its technical committees and IEC National Committees for any personal injury, property damage or
86 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
87 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
88 Publications.
89 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
90 indispensable for the correct application of this publication.
91 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
92 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
93 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
94 may be required to implement this document. However, implementers are cautioned that this may not represent
95 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
96 shall not be held responsible for identifying any or all such patent rights.
97 International Standard IEC 62381 has been prepared by subcommittee 65E: Devices and
98 integration in enterprise systems, of IEC technical committee 65: Industrial-process
99 measurement, control and automation.
100 This third edition cancels and replaces the second edition published in 2012. This edition
101 constitutes a technical revision.
102 The main changes with respect to the previous edition are listed below:

127 INTRODUCTION
128 There is an increasing trend in the process industry to shorten the time period for project
129 execution. At the same time, the complexity of automation systems is being increased due to
130 the number of connected systems and the use of new technologies, for example, fieldbus
131 systems.
132 Experience has shown that the owner, the buyer and the vendor have long and extensive
133 discussions to unambiguously establish the scope of activities and responsibilities in order to
134 achieve a timely delivery and acceptance of automation systems.
135 This standard is intended to provide requirements and guidance on acceptance testing of
136 control system installations, lead to an improvement and acceleration of the negotiation phase,
137 and lead to a mutual understanding about the scope of activities of each party.

322 4 Overview of automation system testing
323 4.1 General
324 An automation system is to be tested at various stages in its development and
325 implementation. Each new automation system shall be subjected to three tests to demonstrate
326 proper operation in accordance with project-specific requirements: Factory Acceptance Test
327 (FAT), Site Acceptance Test (SAT) and Site Integration Test (SIT). After the SAT, loop tests
328 shall be performed in accordance with IEC 62382. All these tests shall be completed, with any
329 open items documented and agreed upon, prior to the system being placed in operation. An
330 optional fourth test, Factory Integration Test (FIT) can also be performed on all or part of the
331 system while at the vendor’s factory.
332 Note: Refer to IEC 62337 for the typical sequence of project phases noted in this document.
333 The typical order of execution of these tests is:
334 • The Factory Acceptance Test (FAT) is performed on the automation system, sub-system
335 or component before it leaves the vendor’s factory to demonstrate that it functions in
336 accordance with the project specific requirements.
337 • The Factory Integration Test (FIT) is a fourth, optional testing point to demonstrate that
338 the merging of some or all of the various subsystems and components function as
339 specified. This test is performed after or in conjunction with the FAT, before the
340 automation system, sub-system or component leaves the vendor’s factory.
341 • The Site Acceptance Test (SAT) is performed after installation on site to demonstrate the
342 automation system, subsystem, or component is in accordance with the applicable
343 standards, codes, specifications, and installation instructions. This test is performed after
344 each sub-system is installed.
345 • The Site Integration Test (SIT) is performed after the SAT to demonstrate that the merging
346 of the various subsystems and components into one overall automation system is
347 complete and that all sub-systems and components work together as specified. This test

---------------------- Page: 13 ----------------------
oSIST prEN IEC 62381:2023
– 12 – IEC CDV 62381 © IEC:2023
348 can be performed on two or more sub-systems or components after each has been
349 installed and successfully completed an SAT or after all sub-systems and components
350 have been installed and successfully completed an SAT.
351 4.2 Methods of test performance
352 This standard provides checklists for developing test plans for the automation system.
353 Traditionally, these tests are performed using manual methods. With modern systems, these
354 tests can also be performed using automated methods, depending on the system’s capability.
355 If automated methods are used, it is the vendor’s responsibility to demonstrate that the
356 automated tests completely cover all aspects
