76 FOREWORD
77 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
78 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
79 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
80 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
81 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
82 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
83 in the subject dealt with may participate in this preparatory work. International, governmental and non-
84 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
85 with the International Organization for Standardization (ISO) in accordance with conditions determined by
86 agreement between the two organizations.
87 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
88 consensus of opinion on the relevant subjects since each technical committee has representation from all
89 interested IEC National Committees.
90 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
91 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
92 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
93 misinterpretation by any end user.
94 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
95 transparently to the maximum extent possible in their national and regional publications. Any divergence
96 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
97 the latter.
98 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
99 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
100 services carried out by independent certification bodies.
101 6) All users should ensure that they have the latest edition of this publication.
102 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
103 members of its technical committees and IEC National Committees for any personal injury, property damage or
104 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
105 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
106 Publications.
107 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
108 indispensable for the correct application of this publication.
109 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
110 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
111 International Standard IEC 61340-4-9 has been prepared by IEC technical committee 101:
112 Electrostatics.
113 This third edition cancels and replaces the second edition published in 2010. This edition
114 constitutes a technical revision.
115 This edition includes the following significant technical changes with respect to the previous
116 edition:
117 a) IEC 61010-1 and IEC 61010-2-030 were added as requirements for measurement
118 equipment
119 b) Testing voltage for personal ground path changed from 7 V DC to 30 V DC to 7 V DC to
120 100 V DC
121 c) Cleaning requirements changed from a minimum of 5 cycles of cleaning to a minimum of 3
122 cycles of cleaning.
