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.
This International Standard IEC 62642-8 has been prepared by IEC technical committee 79:
Alarm and electronic security systems.This standard is based on EN 50131-8 (2009).
The text of this standard is based on the following documents:

INTRODUCTION
This part 8 of the IEC 62642 series of standards gives requirements for security fog
device/systems used in intrusion and hold-up alarm systems. The other parts of this series of
standards are as follows:Part 1 System requirements
Part 2-2 Intrusion detectors – Passive infrared detectors
Part 2-3 Intrusion detectors – Microwave detectors
Part 2-4 Intrusion detectors – Combined passive infrared / microwave detectors
Part 2-5 Intrusion detectors – Combined passive infrared / ultrasonic detectors
Part 2-6 Intrusion detectors – Opening contacts (magnetic)
Part 2-71 Intrusion detectors – Glass break detectors – Acoustic
Part 2-72 Intrusion detectors – Glass break detectors – Passive
Part 2-73 Intrusion detectors – Glass break detectors – Active
Part 3 Control and indicating equipment
Part 4 Warning devices
Part 5-3 Interconnections – Requirements for equipment using radio frequency techniques
Part 6 Power suppliesPart 7 Application guidelines
Part 8 Security fog devices/systems
This International Standard applies to a security fog system that is part of an Intruder and
Hold-up Alarm System (I&HAS) and is used both as a security deterrent device for building
security and as a crime reduction device for the protection of people.This International Standard is intended to assist insurers, intruder alarm companies,
customers and the police in understanding the principles and specification of a security fog
system.The purpose of a security fog system is to reduce the visibility in a protected area by the use
of a non-toxic fog in order to form a barrier between the criminal and the criminal’s intended
target.This International Standard is not intended to cover standalone or mobile security fog
systems.This International Standard has been designed to be flexible enough to encourage and
encompass future developments in the field of security fog systems.---------------------- Page: 8 ----------------------

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 62642-1, as well as
the following apply.3.1.1
confirmed intrusion
signals or messages emanating from two or more independent intrusion detectors indicating
there is a high probability that a genuine intrusion or genuine attempted intrusion has
occurred within a specified timeframe3.1.2
obscuration
the reduction in visibility as a result of the activation of a security fog system
---------------------- Page: 9 ----------------------– 8 – 62642-8 IEC:2011
3.1.3
protected area
the designated space the security fog system is designed to restrict the visibility in when
operated3.1.4
security fog system
device (or a series of separate independent components that make up a device) or system
within tamper resistance housing(s), that, when activated, produces a dense artificial fog,
from a consumable, to reduce visibility in the protected area3.1.5
verification
