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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62685, which is a technical report, has been prepared by subcommittee 65C: Industrial
networks, of IEC technical committee 65: Industrial-process measurement, control and
automation.

INTRODUCTION
During the development of IEC 61784-3:2010, the need was recognized for a separate
document covering environmental tests, proofs and information checks, which were currently
1
specified in the German document GS-ET-26 [37] . This document has been one of the
starting points for IEC 61784-3 and most of its contents have been already taken into account
in IEC 61784-3. The material related to environmental tests, proofs and information checks
has been transformed, updated and supplemented into this new document.
NOTE IEC 61784-3 explains the relevant principles for functional safety communications with reference to
IEC 61508 series and specifies several safety communication layers (profiles and corresponding protocols) based
on the communication profiles and protocol layers of IEC 61784-1, IEC 61784-2 and the IEC 61158 series.
2
The combination of the IEC 61508 series , with its new view on complete safety functions,
and of the FSCPs in the IEC 61784-3 series, eases the implementation of safety functions.
Further benefits can be achieved, if the environmental conditions can be defined and
harmonized for FSCP devices.
The objective of this document is to specify the requirements for FSCP devices on how to
fulfill environmental and deployment conditions. It addresses the needs of designers,
manufacturers, assessment bodies, and test laboratories.
Figure 1 provides a basic overview on safety functions, FSCP devices and the impact of the
environment. It demonstrates the necessity of harmonized environmental requirements.

1 Scope
This Technical Report provides information about the assessment aspects of safe
communication such as test beds, proof of increased interference immunity (EMC for
functional safety), electrical safety, and other environmental requirements.
This document is only applicable to safety devices for functional safety communication which
are developed according to IEC 61508 and IEC 61784-3.
NOTE This document does not cover the more complex aspects of preserving existing devices and applications in
the field and migration from safety rules before IEC 61508.
The scope covers general industrial environments such as defined in IEC 61131-2 or
IEC 61000-6-2 and process automation environments such as those covered in the IEC 61326
series.
Reference is made to the ERS (Equipment Requirements Specification) and/or SRS (Safety
Requirements Specification) of a particular safety application to verify the necessary immunity
of devices and systems according to IEC 61508.
