63 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
64 FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
66 Part 2-034: Particular requirements for measurement equipment
67 for insulation resistance and test equipment for electric strength
69 FOREWORD
70 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
71 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -
72 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
73 addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
74 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their preparation
75 is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
76 participate in this preparatory work. International, governmental and non-governmental organizations liaising with
77 the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
78 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
79 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
80 consensus of opinion on the relevant subjects since each technical committee has representation from all interested
81 IEC National Committees.
82 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
83 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
84 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
85 misinterpretation by any end user.
86 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
87 transparently to the maximum extent possible in their national and regional publications. Any divergence between
88 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
89 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
90 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services
91 carried out by independent certification bodies.
92 6) All users should ensure that they have the latest edition of this publication.
93 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
94 members of its technical committees and IEC National Committees for any personal injury, property damage or
95 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
96 arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
97 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
98 indispensable for the correct application of this publication.
99 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
100 rights. IEC shall not be held responsible for identifying any or all such patent rights.
101 International Standard IEC 61010-2-034 has been prepared by IEC technical committee 66:
102 Safety of measuring, control and laboratory equipment.
103 It has the status of a group safety publication in accordance with IEC Guide 104.
104 This second edition cancels and replaces the first edition published in 2017. This edition
105 constitutes a technical revision.
106 The text of this International Standard is based on the following documents:
FDIS Report on voting
66/xxx/FDIS 66/xxx/RVD
108 Full information on the voting for the approval of this International Standard can be found in the
109 report on voting indicated in the above table.
