71 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

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

73 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

74 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

75 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

76 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

77 in the subject dealt with may participate in this preparatory work. International, governmental and non-

78 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

79 with the International Organization for Standardization (ISO) in accordance with conditions determined by

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

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

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

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

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

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

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

90 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

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

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

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

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

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

98 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

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

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

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

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

105 International Standard IEC 61326-1 has been prepared by subcommittee 65A: System

106 aspects, of IEC technical committee 65: Industrial-process measurement, control and

108 This third edition cancels and replaces the second edition, published in 2012. This edition

110 The significant technical changes with respect to the previous edition are as follows:

112 – requirements for PORTABLE TEST AND MEASUREMENT EQUIPMENT have been clarified and

124 A list of all parts of the IEC 61326 series under the general title Electrical equipment for

125 measurement, control and laboratory use – EMC requirements, can be found on the IEC

127 The committee has decided that the contents of this publication will remain unchanged until

128 the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

137 Instruments and equipment within the scope of this standard may often be geographically

139 The limitation of undesired electromagnetic emissions ensures that no other equipment,

140 installed nearby, is unduly influenced by the equipment under consideration. The limits are

141 more or less specified by, and therefore taken from, IEC and International Special Committee

143 However, the equipment should function without undue degradation in an electromagnetic

144 environment typical for the locations where it is intended to be operated. In this respect the

145 standard specifies three different types of electromagnetic environment and the levels for

146 immunity. More detailed information about issues related to electromagnetic environments are

147 given in IEC 61000-2-5. Special risks, involving for example nearby or direct lightning strikes,

148 circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are not

151 design and installation, taking into consideration the electromagnetic environment, any

153 This part of IEC 61326 specifies the EMC requirements that are generally applicable to all

154 equipment within its scope. For certain types of equipment, these requirements will be

155 supplemented or modified by the special requirements of one, or more than one, particular

156 part within IEC 61326-2 series. These should be read in conjunction with the IEC 61326-1

169 This part of IEC 61326 specifies requirements for immunity and emissions regarding electro-

170 magnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of

171 less than 1 000 V AC or 1 500 V DC or from the circuit being measured. Equipment intended

172 for professional, industrial-process, industrial-manufacturing and educational use is covered

177 – accessories intended for use with the above (such as sample handling equipment),

179 Computing devices and assemblies and similar equipment within the scope of Information

180 Technology Equipment (ITE) and complying with applicable ITE EMC standards may be used

181 in systems within the scope of this part of IEC 61326 without additional testing, if they are
