53 FOREWORD
54 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
55 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
56 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
57 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
58 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
59 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
60 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
61 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
62 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence between
72 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
73 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
74 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
75 services carried out by independent certification bodies.
76 6) All users should ensure that they have the latest edition of this publication.
77 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
78 members of its technical committees and IEC National Committees for any personal injury, property damage or
79 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
80 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
81 Publications.
82 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
83 indispensable for the correct application of this publication.
84 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
85 rights. IEC shall not be held responsible for identifying any or all such patent rights.
86 International Standard IEC 1557-14 has been prepared by WG8: Measuring and monitoring
87 equipment for testing protective devices in energy distribution systems, of IEC technical
88 committee TC85: Measuring equipment for electrical and electromagnetic quantities.
89 This second edition cancels and replaces the first edition published in 2013. This edition
90 constitutes a technical revision.
91 This edition includes the following significant technical changes with respect to the previous
92 edition:
93 a) Clarifying the introduction;
94 a) Replaced ‘dielectric strength’ by ‘voltage test’;

120 INTRODUCTION
121 This standard defines particular requirements for test and measurement equipment used to
122 determine the electrical safety of electrical equipment of machinery. IEC 61010, other parts of
123 the IEC 61557 series and IEC 60204 do not cover all safety aspects of equipment used for
124 testing electrical equipment of machinery in accordance with the test sequence of IEC 60204-1.
125 This part of IEC 61557 provides additional measures to reduce the risk of electric shock for the
126 test persons and bystanders during voltage tests in the field. The standard also defines
127 performance requirements for each test and measurement function to ensure reliable and
128 comparable results.
