46 FOREWORD
48 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
49 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-
50 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
51 other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available
52 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical
53 committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.
54 International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
55 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
56 determined by agreement between the two organizations.57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC
59 National Committees.60 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees
61 in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate,
62 IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
63 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently
64 to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication
65 and the corresponding national or regional publication shall be clearly indicated in the latter.
66 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
67 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
68 independent certification bodies.69 6) All users should ensure that they have the latest edition of this publication.
70 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
71 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
72 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the
73 publication, use of, or reliance upon, this IEC Publication or any other IEC 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 patent rights.
77 IEC shall not be held responsible for identifying any or all such patent rights.
78 International Standard IEC 61557-2 has been prepared by subcommittee TC85: Measuring equipment
79 for electrical and electromagnetic quantities.80 This third edition cancels and replaces the second edition published in 2007. This edition constitutes a
81 technical revision.82 This edition includes the following significant technical changes with respect to the previous edition:
83 a) requirement for measurement category added84 b) new requirements for operating instructions added
85 c) Alignment of the structure to the whole series IEC 61557
