45 FOREWORD
46 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
47 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
48 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
49 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
50 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
51 Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
52 in the subject dealt with may participate in this preparatory work. International, governmental and non-
53 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
54 with the International Organization for Standardization (ISO) in accordance with conditions determined by
55 agreement between the two organizations.
56 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
57 consensus of opinion on the relevant subjects since each technical committee has representation from all
58 interested IEC National Committees.
59 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
60 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
61 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
62 misinterpretation by any end user.
63 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
64 transparently to the maximum extent possible in their national and regional publications. Any divergence
65 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
66 the latter.
67 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
68 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
69 services carried out by independent certification bodies.
70 6) All users should ensure that they have the latest edition of this publication.
71 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
72 members of its technical committees and IEC National Committees for any personal injury, property damage or
73 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
74 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
75 Publications.
76 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
77 indispensable for the correct application of this publication.
78 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
79 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
80 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
81 which may be required to implement this document. However, implementers are cautioned that this may not
82 represent the latest information, which may be obtained from the patent database available at
83 https://patents.iec.ch or www.iso.org/patents. IEC shall not be held responsible for identifying any or all such
84 patent rights.
85 IEC 61554 has been prepared by IEC technical committee 85: Measuring equipment for
86 electrical and electromagnetic quantities.
87 This second edition cancels and replaces the first edition published in 1999.
IEC CDV 61554 CDV IEC:2024 – 4 – 85/913/CDV
88 This edition includes the following significant technical changes with respect to the previous
89 edition:
90 a) Complement more sizes and tolerances of instruments and some practical information for
91 panel mounting which were not mentioned in IEC 61554:1999;
92 b) Modify several current sizes and tolerance of instruments ;
93 c) Update the Figures in Annex A;
94 d) Change Annex A from Informative Annex into Nornative Annex.
95 The text of this International Standard is based on the following documents:

115 DIMENSIONS FOR PANEL MOUNTING
119 1 Scope
120 This International Standard defines a system of dimensions for panel mounting of equipment.
121 It is applicable to electrical and electrically operated indicating, recording and control
122 instruments.
123 It applies to the following types of instruments with protruding bezels:
124 • instruments with square housing;
125 • instruments with rectangular housing with lateral orientation;
126 • instruments with rectangular housing with upright orientation;
127 • instruments with round housing and square bezel;
128 • instruments with round housing and rectangular bezel.
129 The purpose of this standard is to establish dimensional interchangeability between instruments
130 made by different manufacturers. To fulfil this requirement, a defined set of dimensions has
131 been chosen. Using these dimensions, it should be easy to combine instruments of different
132 sizes on the same panel making good use of the available panel space and to produce a
133 satisfactory layout.
134 2 Normative references
135 There are no normative references in this document.
136 3 Terms and definitions
137 For the purposes of this document, the following terms and definitions apply.

149 instrument size
150 the overall maximum width and height of the bezel
151 4 Requirements
152 4.1 General
153 The instrument size serves as a basis for defining the various dimensions which permit
154 interchangeability of the instrument.
155 Only positive tolerances are allowed for cut-out dimensions and only negative tolerances for
156 the instrument size.
157 The dimensions of the housings of the instruments are not specified in this standard. The only
158 exception to this is instruments with round housing which are covered in annex A.
159 Instruments that are mounted together in a common cut-out are shown as mounted without any
