64 FOREWORD
65 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
66 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
67 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
68 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
69 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
70 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
71 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
72 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
73 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
74 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
75 consensus of opinion on the relevant subjects since each technical committee has representation from all
76 interested IEC National Committees.
77 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
78 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
79 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
80 misinterpretation by any end user.
81 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
82 transparently to the maximum extent possible in their national and regional publications. Any divergence between
83 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
84 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
85 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
86 services carried out by independent certification bodies.
87 6) All users should ensure that they have the latest edition of this publication.
88 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
89 members of its technical committees and IEC National Committees for any personal injury, property damage or
90 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
91 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
92 Publications.
93 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
94 indispensable for the correct application of this publication.
95 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
96 rights. IEC shall not be held responsible for identifying any or all such patent rights.
97 International Standard IEC 61557-16 has been prepared by IEC technical committee 85:
98 Measuring equipment for electrical and electromagnetic quantities.
99 This second edition cancels and replaces the first edition published in 2014. This edition
100 constitutes a technical revision.
101 This edition includes the following significant technical changes with respect to the previous
102 edition:
103 a) splitting of uncertainty requirements for medical and non-medical electrical equipment in
104 4.2.1
105 b) addition of a definition of ranges with defined uncertainty in 4.1.2 up to 4.1.7
106 c) addition of an optional measuring device (MD) for non-medical devices in 4.2.1.
107 d) addition of a limitation of the maximum intrinsic uncertainty for medical applications at
108 leakage current in 4.2.1

109 e) change of 4.2.3 from test sockets to sockets for service purposes;
110 f) addition of a warning in the operating instructions;
111 g) integration of former 6.3 into 6.2;
112 h) update of Table 1;
113 i) alignment of the structure with that of the whole IEC 61557 series.
