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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which

INTRODUCTION
Compliance verification is the process of monitoring and measuring all elements of an ESD
control program. Regular compliance verification checks and tests are an essential part of this
process, ensure that area precautions and equipment remain effective, and that an ESD control
program is correctly implemented in compliance with an organization's ESD control program
plan.
Qualification testing is typically carried out under controlled conditions, often in a laboratory
environment, and using industry recognized standards. Compliance verification testing is
carried out under operational conditions using test methods that are appropriate to a user's
requirements. Although qualification test methods can be used, compliance verification testing
often uses simple equipment and procedures. Accuracy is still important, but of equal
importance is the ability to carry out non-destructive testing without interrupting the normal
business of the organization.
This document describes equipment and test methods that can be used for compliance
verification testing of ESD control items and systems and provides users with troubleshooting
guidance regarding the verification procedures for the ESD control items.

IEC TS 61340-5-4 © IEC 2026
1 Scope
This part of IEC 61340 describes compliance verification testing for technical items included in
ESD control programs, such as those specified in IEC 61340-5-1.
Test methods are based on those specified in IEC 61340-5-1 and other parts of the IEC 61340
series and are simplified, where appropriate, for the purposes of compliance verification.
This document describes compliance verification procedures intended for use by competent
personnel familiar with the operation of test equipment and knowledgeable about the ESD
control items being verified.
Organizations can, by reference to this document in their compliance verification plan, adopt
the necessary compliance verification procedures described herein without change or addition.
Alternatively, compliance verification procedures described in this document can be adapted to
match the organization's ESD control program requirements, provided deviations in test
equipment and compliance verification procedures are documented in their compliance
verification plan.
Product qualification is excluded from the scope of this document.

5 General aspects
5.1 Use of this document
This document is organized by compliance verification clauses based on the order that the ESD
control items are referenced in IEC 61340-5-1. It is separated into general compliance
verification objectives; a listing of IEC 61340 series documents that the compliance verification
procedure is based upon; and test equipment needed to perform the compliance verification,
followed by compliance verification procedures using various test equipment, as applicable.
Figures that follow the compliance verification procedures are intended as examples only and
should be modified by the user as necessary. The troubleshooting clause offers guidance for
addressing common issue with test equipment used in the compliance verification process. For
information and guidance on error consideration and uncertainty of measurements, refer to
IEC TR 61340-1-1 [2] .
Test equipment shall be verified to be working properly before performing compliance
verification procedures.
– Initial compliance verification procedures should be applied when the ESD control item is
first brought into service. Subsequent compliance verification of the ESD control item should
