63 FOREWORD

64 1) The International Electrotechnical Commission (IEC) is a worldwide organization for st andardization comprising

65 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

66 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

67 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

68 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

69 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

70 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

71 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

72 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

73 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

74 consensus of opinion on the relevant subjects since each technical committee has representation from all

75 interested IEC National Committees.

76 3) IEC Publications have the form of recommendations for international use and are accepted by I EC National

77 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

78 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

79 misinterpretation by any end user.

80 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

81 transparently to the maximum extent possible in their national and regional publications. Any divergence between

82 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

83 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

84 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

85 services carried out by independent certification bodies.

86 6) All users should ensure that they have the latest edition of this publication.

87 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

88 members of its technical committees and IEC National Committees for any personal injury, property damage or

89 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal f ees) and

90 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

91 Publications.

92 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

93 indispensable for the correct application of this publication.

94 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

95 rights. IEC shall not be held responsible for identifying any or all such patent rights.

96 IEC 61010-2-033 has been prepared by IEC technical committee 66: Safety of measuring,

97 control and laboratory equipment.

98 It has the status of a group safety publication in accordance with IEC Guide 104.

99 This third edition cancels and replaces the second edition published in 2019. This edition

100 constitutes a technical revision.

145 INTRODUCTION

146 IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment

147 within its scope. For certain types of equipment, the requirements of IEC 61010-1 and its

148 amendment will be supplemented or modified by the special requirements of one, or more than

149 one, particular Part 2 which are read in conjunction with the Part 1 requirements.

150 1) Part 2-030 specifies the safety requirements for equipment with testing or measuring

151 circuits which are connected for test or measurement purposes to devices or circuits outside

152 the measurement equipment itself.

153 2) Part 2-032 specifies the safety requirements for hand-held and hand-manipulated current

154 sensors for measuring, detecting, injecting current, or indicating current waveforms on

155 circuits without physically opening the current path of the circuit being measured.

156 Most of the requirements of Part 2-030 have been included into Part 2-032. Equipment

157 within the scopes of both Part 2-030 and Part 2-032 are considered to be covered by the

158 requirements of Part 2-032.

159 However, for current sensor in combined equipment with protective bonding and automatic

160 disconnection of the supply, Part 2-030 and Part 2-032 are read in conjunction

161 3) Part 2-033 specifies the safety requirements for hand-held multimeters and other meters for

162 domestic and professional use, capable of measuring mains voltage, intended to measure

163 voltage and other electrical quantities such as resistance or current.
164 All relevant requirements of Part 2-030 have been included into Part 2-033.

165 4) Part 2-034 specifies the safety requirements for measurement equipment for insulation

166 resistance and test equipment for electric strength which are connected to units, lines or

167 circuits for test or measurement purposes.

168 All relevant requirements of Part 2-030 have been included into Part 2-034. However, for

169 equipment within the scope of Part 2-032 and Part 2-034, these standards are read in

170 conjunction.

171 IEC 61010-031 specifies the safety requirements for hand-held and hand-manipulated probe

172 assemblies and their related accessories intended to be used in particular with equipment in

173 the scope of Part 2-030, Part 2-032, Part 2-033 and Part 2-034. These probe assemblies are

174 for non-contact or direct electrical connection between a part and electrical test and

175 measurement equipment. They may be fixed to the equipment or be detachable accessories for

176 the equipment.
