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

edition:

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: 11 ----------------------
– 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
Surface conductive materials shall have a surface resistance of < 1 × 10 Ω.
b) Volume conductive materials
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.

NOTE The thickness of the material can have a significant influence on the measured value of volume resistance.

---------------------- Page: 12 ----------------------
IEC 61340-5-3:2022  IEC 2022 – 11 –
6.2.4 Resistance of insulating materials

Electrostatic insulating materials can be surface insulating, volume insulating or both.

a) Surface insulating materials
Electrostatic surface insulating materials have a surface resistance ≥ 1 × 10 Ω.
b) Volume insulating materials
Electrostatic volume insulating materials have a volume resistance ≥ 1 × 10 Ω.
6.3 Material electrostatic shielding properties

NOTE Electrostatic shielding materials protect packaged ESDSs from the effects of electrostatic discharges and

fields that are external to the packaging.
6.3.1 Electrostatic discharge shielding

Electrostatic discharge shielding packaging is capable of attenuating an electrostatic discharge.

The calculated energy allowed inside an electrostatic discharge shielding bag shall be less than

20 nJ when tested according to IEC 61340-4-8 or equivalent test method modified to

accommodate the product.
6.3.2 Electrostatic field shielding

Electrostatic field shielding packaging is capable of attenuating an electrostatic field.

See Annex C.
7 Technical requirements for ESD protective packaging
7.1 Packaging and material properties

Table 1 and Table 2 provide test methods for determining material classifications for finished

packaging and materials. When possible, testing shall be performed on the finished packaging.

When testing cannot be performed on a finished packaging, the material classification shall be

defined by the bulk material used for the production of the final packaging.

Other probes (electrodes) may be used providing the results correlate with the specified probes

(electrodes). In case of dispute, the probe (electrode) assemblies specified in IEC 61340-2-3

shall be used.
