46 FOREWORD
47 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
48 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
49 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
50 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
51 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
52 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
53 in the subject dealt with may participate in this preparatory work. International, governmental and non -
54 governmental organizations liaising with the IEC also participate in this preparation. IEC col laborates closely
55 with the International Organization for Standardization (ISO) in accordance with conditions determined by
56 agreement between the two organizations.
57 2) The formal decisions or agreements of IEC on technical matters express, as nearly as pos sible, an international
58 consensus of opinion on the relevant subjects since each technical committee has representation from all
59 interested IEC National Committees.
60 3) IEC Publications have the form of recommendations for international use and are accepte d by IEC National
61 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
62 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
63 misinterpretation by any end user.
64 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
65 transparently to the maximum extent possible in their national and regional publications. Any divergence
66 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
67 the latter.
68 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
69 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
70 services carried out by independent certification bodies.
71 6) All users should ensure that they have the latest edition of this publication.
72 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
73 members of its technical committees and IEC National Committees for any personal injury, property damage or
74 other damage of any nature whatsoever, whether direct or indirect, or for costs (including l egal fees) and
75 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
76 Publications.
77 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
78 indispensable for the correct application of this publication.
79 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
80 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
81 International Standard IEC 61340-5-1 has been prepared by IEC technical committee 101:
82 Electrostatics.

114 INTRODUCTION
115 This part of IEC 61340 covers the requirements necessary to design, establish, implement
116 and maintain an electrostatic discharge (ESD) control program for activities that: manufacture,
117 process, assemble, install, package, label, service, test, inspect, transport or otherwise
118 handle electrical or electronic parts, assemblies and equipment susceptible to damage by
119 electrostatic discharges greater than or equal to 100 V human body model (HBM), 200 V
120 charged device model (CDM) and 35 V on isolated conductors. Isolated conductors were
121 historically represented by machine model (MM). The 35 V limit is related to the level
122 achievable using ionizers specified in this standard. The MM test is no longer required for
123 qualification of devices, only the HBM and CDM tests are. The requirements relating to MM
124 are retained in this standard for process control of isolated conductors only.
125 Any contact and physical separation of materials or flow of solids, liquids, or particle-laden
126 gases can generate electrostatic charges. Common sources of ESD include charged:
127 personnel, conductors, common polymeric materials, and processing equipment. ESD
128 damage can occur when:
129 • a charged person or object comes into contact with an ESD sensitive device (ESDS);
130 • an ESDS comes into direct contact with a highly conductive surface while exposed to an
131 electrostatic field;
132 • a charged ESDS comes into contact with another conductive surface which is at a different
133 electrical potential. This surface can be grounded or ungrounded.
134 Examples of ESDS are microcircuits, discrete semiconductors, thick and thin film resistors,
135 hybrid devices, printed circuit boards and piezoelectric crystals. It is possible to determine
136 device and item susceptibility by exposing the device to simulated ESD events. The ESD
137 withstand voltage determined by sensitivity tests using simulated ESD events does not
138 necessarily represent the ability of the device to withstand ESD from real sources at that
139 voltage level. However, the levels of sensitivity are used to establish a baseline of
140 susceptibility data for comparison of devices with equivalent part numbers from different
141 manufacturers. Three different models have been used for qualification of electronic
142 components – HBM, MM, and CDM. In current practice devices are qualified only using HBM
143 and CDM susceptibility tests.
144 This standard covers the ESD control program requirements necessary for setting up a
145 program to handle ESDS, based on the historical experience of both military and commercial
146 organizations. The fundamental ESD control principles that form the basis of this standard are
147 as follows.
148 • Avoid a discharge from any charged, conductive object (personnel and especially
149 automated handling equipment) into the ESDS. This can be accomplished by bonding or
150 electrically connecting all conductors in the environment, including personnel, to a known
151 ground or contrived ground (as on board ship or on aircraft). This attachment creates an
152 equipotential balance between all conducting objects and personnel. Electrostatic
153 protection can be maintained at a potential different from a “zero” voltage ground potential
154 as long as all conductive objects in the system are at the same potential.
155 • Avoid a discharge from any charged ESD sensitive device. Charging can result from direct
156 contact and separation or it can be induced by an electric field. Necessary insulators in
157 the environment cannot lose their electrostatic charge by attachment to ground. Ionization
158 systems provide neutralization of charges on these necessary insulators (circuit board
159 materials and some device packages are examples of necessary insulators). The ESD
160 hazard created by electrostatic charges on the necessary insulators in the work place is
161 assessed to ensure that appropriate actions are implemented, according to the risk.
162 • Once outside of an electrostatic discharge protected area (hereinafter referred to as an
163 EPA) it is generally not possible to control the above items, therefore, ESD protective
164 packaging can be required. ESD protection can be achieved by enclosing ESD sensitive
165 products in static protective materials, although the type of material depends on the
166 situation and destination. Inside an EPA, static dissipative materials can provide adequate
167 protection. Outside an EPA, static discharge shielding materials are recommended. Whilst
168 all of these materials are not discussed in this standard, it is important to recognize the

169 differences in their application. For more information see IEC 61340-5-3 and IEC TR
170 61340-5-5.
171 Each organization has different processes, and so will require a different blend of ESD
172 prevention measures for an optimum ESD control program. Measures should be selected,
173 based on technical necessity and carefully documented in an ESD control program plan, so
174 that all concerned can be sure of the program requirements.
175 Training is an essential part of an ESD control program in order to ensure that the personnel
176 involved understand the equipment and procedures they are to use in order to be in
177 compliance with the ESD control program plan. Training is also essential in raising awareness
178 and understanding of ESD issues. Without training, personnel are often a major source of
179 ESD risk. With training, they become an effective first line of defence against ESD damage.
180 Product qualification ensures that equipment sourced for use in the ESD control program
181 meets the technical requirements before it is placed in service. A product qualification plan
182 details the criteria to be used for selection of ESD control items.
183 Regular compliance verification checks and tests are essential to ensure that equipment
184 remains effective and that the ESD control program is correctly implemented in compliance
185 with the ESD control program plan.

194 1 Scope
195 This part of IEC 61340 applies to organizations that: manufacture, process, assemble, install,
196 package, label, service, test, inspect, transport or otherwise handle electrical or electronic
197 parts, assemblies and equipment with withstand voltages greater than or equal to 100 V
198 human body model (HBM) and 200 V charge device model (CDM). Also, protection from
199 isolated conductors is addressed by limiting the voltage on isolated conductors to less than
200 35 V. ESDS with lower withstand voltages can require additional control elements or adjusted
201 limits. Processes designed to handle items that have lower ESD withstand voltage(s) may still
202 claim compliance to this standard.
