Electrostatics - Part 4-6: Standard test methods for specific applications - Wrist straps
This part of IEC 61340 provides electrical and mechanical test methods and performance limits for evaluation, acceptance and periodic verification testing of wrist straps. NOTE All dimensions are nominal except where indicated. This standard is intended for testing wrist straps and wrist strap systems used for the grounding of personnel engaged in working with ESD sensitive assemblies and devices. It does not address constant monitoring systems.

75 FOREWORD
76 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
77 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
78 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
79 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
80 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
81 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
82 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
83 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
84 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
85 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
86 consensus of opinion on the relevant subjects since each technical committee has representation from all
87 interested IEC National Committees.
88 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
89 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
90 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
91 misinterpretation by any end user.
92 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
93 transparently to the maximum extent possible in their national and regional publications. Any divergence between
94 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
95 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
96 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
97 services carried out by independent certification bodies.
98 6) All users should ensure that they have the latest edition of this publication.
99 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
100 members of its technical committees and IEC National Committees for any personal injury, property damage or
101 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
102 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
103 Publications.
104 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
105 indispensable for the correct application of this publication.
106 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
107 rights. IEC shall not be held responsible for identifying any or all such patent rights.
108 IEC 61340-4-6 has been prepared by IEC technical committee 101: Electrostatics. It is an
109 International Standard.
110 This third edition cancels and replaces the second edition published in 2015. This edition
111 constitutes a technical revision.
112 This edition includes the following significant technical changes with respect to the previous
113 edition:
114 a) editorial comments made during the review of the second edition were reviewed and
115 incorporated where appropriate;
116 b) addition of a normative section, clause 2 to address safety of equipment;
117 The text of this International Standard is based on the following documents:
