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 61326-2-5 has been prepared by subcommittee 65A: System

aspects, of IEC technical committee 65: Industrial-process measurement, control and

automation.

This third edition cancels and replaces the second edition published in 2012. This edition

constitutes a technical revision.

This edition includes the following significant technical change with respect to the previous

edition:
– update with respect to IEC 61326-1:2020.

Full information on the voting for the approval of this International Standard can be found in the

report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

This part of IEC 61326 series is to be used in conjunction with IEC 61326-1:2020 and follows

the same numbering of clauses, subclauses, tables and figures.

When a particular subclause of IEC 61326-1 is not mentioned in this part, that subclause applies

as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,

the relevant text in IEC 61326-1 is to be adapted accordingly.
NOTE The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in IEC 61326-1;

– unless notes are in a new subclause or involve notes in IEC 61326-1, they are numbered starting from 101

including those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.

A list of all parts of IEC 61326 series, under the general title Electrical equipment for

measurement, control and laboratory use – EMC requirements can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be

43 FOREWORD

44 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

45 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

46 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

47 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

48 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

49 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

50 in the subject dealt with may participate in this preparatory work. International, governmental and non-

51 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

52 with the International Organization for Standardization (ISO) in accordance with conditions determined by

53 agreement between the two organizations.

54 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

55 consensus of opinion on the relevant subjects since each technical committee has representation from all

56 interested IEC National Committees.

57 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

58 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

59 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

60 misinterpretation by any end user.

61 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

62 transparently to the maximum extent possible in their national and regional publications. Any divergence

63 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

64 the latter.

65 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

66 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

67 services carried out by independent certification bodies.

68 6) All users should ensure that they have the latest edition of this publication.

69 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

70 members of its technical committees and IEC National Committees for any personal injury, property damage or

71 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

72 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

73 Publications.

74 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

75 indispensable for the correct application of this publication.

76 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

77 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

78 International Standard IEC 61326-2-5 has been prepared by subcommittee 65A: System

79 aspects, of IEC technical committee 65: Industrial-process measurement, control and

80 automation.

81 This third edition cancels and replaces the second edition published in 2012. This edition

82 constitutes a technical revision.

88 Full information on the voting for the approval of this standard can be found in the report on

89 voting indicated in the above table.

90 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

91 This part of IEC 61326 series is to be used in conjunction with IEC 61326-1:20xx and follows

92 the same numbering of clauses, subclauses, tables and figures.

93 When a particular subclause of IEC 61326-1 is not mentioned in this part, that subclause

94 applies as far as is reasonable. When this standard states “addition”, “modification” or

95 “replacement”, the relevant text in IEC 61326-1 is to be adapted accordingly.
96 NOTE The following numbering system is used:

97 – subclauses, tables and figures that are numbered starting from 101 are additional to those in

98 IEC 61326-1;

99 – unless notes are in a new subclause or involve notes in IEC 61326-1, they are numbered starting from 101

100 including those in a replaced clause or subclause;
101 – additional annexes are lettered AA, BB, etc.

102 A list of all parts of IEC 61326 series, under the general title Electrical equipment for

103 measurement, control and laboratory use – EMC requirements can be found on the IEC

104 website.

105 The committee has decided that the contents of this publication will remain unchanged until

106 the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

107 related to the specific publication. At this date, the publication will be
