FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 61340-5-3 has been prepared by IEC technical committee 101: Electrostatics. It is an
International Standard.
This third edition cancels and replaces the second edition published in 2015. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

4 Tailoring
This document, or portions thereof, does not necessarily apply to all applications. Tailoring is
accomplished by evaluating the applicability of each requirement for the specific application.
Upon completion of the evaluation, requirements may be added, modified or deleted.
Tailoring decisions, including rationale, shall be documented.
5 Packaging application requirement
5.1 General
Transportation and storage of ESDSs require packaging that provides protection from
electrostatic hazards (for example from an electrostatic discharge). Within an EPA in which all
ESD risks are well controlled, it is possible that ESD protective packaging will not be necessary.
5.2 Inside an EPA
Packaging used within an EPA shall consist of dissipative or conductive materials for intimate
contact.
Additional protection can be necessary for items sensitive to < 100 V for HBM, < 200 V for CDM
and < 35 V for isolated conductors, depending on application and program plan requirements.
NOTE Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM)
damage is a concern.
5.3 Outside an EPA
Transportation and storage of sensitive products outside of an EPA shall be done in packaging
that provides both
a) dissipative or conductive materials for intimate contact,
b) a structure that provides electrostatic discharge shielding.

---------------------- Page: 15 ----------------------
SIST EN IEC 61340-5-3:2022
– 10 – IEC 61340-5-3:2022  IEC 2022
If electrostatic field shielding materials are used to provide discharge shielding, a material that
provides a barrier to current flow should be used in combination with the electrostatic field
shielding material.
NOTE Dissipative materials are preferred for intimate packaging in situations where charged device model (CDM)
damage is a concern.
6 Classification of ESD packaging material properties
6.1 General
Materials and packaging that are useful in preventing damage to ESD sensitive devices exhibit
certain properties. These properties include:
a) resistance properties:
– conductive;
– dissipative;
b) shielding properties:
– electrostatic discharge;
– electrostatic field;
c) low charging properties:
See Annex D.
6.2 Material resistance properties
6.2.1 General
Most standard packaging materials are electrically insulating and insulating materials retain
charge. Making the packaging less insulating provides a path for the charge to dissipate from
the packaging to a material at a lower potential.
Specific ranges of resistance are useful for different purposes. Packaging can be classified by
these resistance ranges of the material used in its construction.
6.2.2 Resistance of conductive materials
Conductive materials can be surface conductive, volume conductive or both.
a) Surface conductive materials
4
Surface conductive materials shall have a surface resistance of < 1 × 10 Ω.
b) Volume conductive materials
4
Volume conductive materials shall have a volume resistance of < 1 × 10 Ω.
NOTE The thickness of the material can have a significant influence on the measured value of volume resistance.
6.2.3 Resistance of dissipative materials
Dissipative materials can be surface dissipative, volume dissipative or both.
a) Surface dissipative materials
4 11
Surface dissipative materials shall have a surface resistance ≥ 1 × 10 and < 1 × 10 Ω.
b) Volume dissipative materials
4 11
Volume dissipative materials shall have a volume resistance ≥ 1 × 10 and < 1 × 10 Ω.
