54 FOREWORD
55 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization compris ing
56 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
57 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
58 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
59 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
60 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
61 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
62 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
63 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
64 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
65 consensus of opinion on the relevant subjects since each technical committee has representation from all
66 interested IEC National Committees.
67 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
68 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
69 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
70 misinterpretation by any end user.
71 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
72 transparently to the maximum extent possible in their national and regional publications. Any divergence between
73 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
74 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
75 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
76 services carried out by independent certification bodies.
77 6) All users should ensure that they have the latest edition of this publication.
78 7) No liability shall attach to IEC or its directors, employees, servants or agents incl uding individual experts and
79 members of its technical committees and IEC National Committees for any personal injury, property damage or
80 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
81 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
82 Publications.
83 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
84 indispensable for the correct application of this publication.
85 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
86 rights. IEC shall not be held responsible for identifying any or all such patent rights.
87 International standard IEC 60601-2-46 has been prepared by IEC subcommittee 62D
88 Electromedical equipment, of IEC technical committee 62: Electrical equipment in medical
89 practice.
90 This third edition cancels and replaces the second edition published in 2010 and constitutes a
91 technical revision. This edition of IEC 60601-2-46 was revised to align structurally with the 2005
92 edition of IEC 60601-1, IEC 60601-1:2005/AMD1:2012 and IEC 60601-1:2005/AMD2:2020.
93 The text of this standard is based on the following documents:

134 INTRODUCTION
135 This particular standard concerns the BASIC SAFETY and ESSENTIAL PERFORMANCE of OPERATING
136 TABLES. It amends and supplements IEC 60601-1:2005, IEC 60601-2:2005/AMD1:2012 and IEC
137 60601-1:2005/AMD2:2020, hereinafter referred to as the general standard.
138 The aim of this third edition is to bring this particular standard up to date with reference to the
139 third edition of the general standard through reformatting and technical changes .
140 The requirements of this particular standard take priority over those of the general standard.
141 A “General guidance and rationale” for the more important requirements of this particular
142 standard is included in Annex AA. It is considered that knowledge of the reasons for these
143 requirements will not only facilitate the proper application of the standard but will, in due course,
144 expedite any revision necessitated by changes in clinical practice or as a result of developments
145 in technology. However, Annex AA does not form part of the requirements of this Standard.

183 IEC 60601-1-2 and IEC 60601-1-3 apply as modified in Clauses 202 and 203 respectively.
184 IEC 60601-1-8, IEC 60601-1-9, IEC 60601-1-10, IEC 60601-1-11 and IEC 60601-1-12 do not
185 apply. All other published collateral standards in the IEC 60601-1 series apply as published.
186 201.1.4 Particular standards
187 Replacement:
188 In the IEC 60601 series, particular standards may modify, replace or delete requirements
189 contained in the general standard and collateral standards as appropriate for the particular ME
190 EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL PERFORMANCE
191 requirements.
192 A requirement of a particular standard takes priority over the general standard.
193 For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.
194 Collateral standards are referred to by their document number.
195 The numbering of clauses and subclauses of this particular standard corresponds to that of the
196 general standard with the prefix “201” (e.g. 201.1 in this standard addresses the content of
197 Clause 1 of the general standard) or applicable collateral standard with the prefix “20x”
198 where is the final digit(s) of the collateral standard document number (e.g. 202.4 in this
199 particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral standard,
200 203.4 in this particular standard addresses the content of Clause 4 of the IEC 60601-1-3
201 collateral standard, etc.). The changes to the text of the general standard are specified by the
202 use of the following words:
203 "Replacement" means that the clause or subclause of the general standard or applicable
204 collateral standard is replaced completely by the text of this particular standard.
205 "Addition" means that the text of this particular standard is additional to the requirements of the
206 general standard or applicable collateral standard.
207 "Amendment" means that the clause or subclause of the general standard or applicable
208 collateral standard is amended as indicated by the text of this particular standard.
209 Subclauses, figures or tables which are additional to those of the general standard are
210 numbered starting from 201.101. However, due to the fact that definitions in the general
211 standard are numbered 3.1 through 3.154, additional definitions in this standard are numbered
212 beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and additional items
213 aa), bb), etc.
214 Subclauses, figures or tables which are additional to those of a collateral standard are
215 numbered starting from 20x, where “x” is the number of the collateral standard, e.g. 202 for
216 IEC 60601-1-2, 203 for IEC 60601-1-3, etc.
217 The term "this standard" is used to make reference to the general standard, any applicable
218 collateral standards and this particular standard taken together.
219 Where there is no corresponding clause or subclause in this particular standard, the clause or
220 subclause of the general standard or applicable collateral standard, although possibly not
221 relevant, applies without modification; where it is intended that any part of the general standard
222 or applicable collateral standard, although possibly relevant, is not to be applied, a statement
223 to that effect is given in this particular standard.
