Introduction
Security Fog Devices are used both as a deterrent device for building security and as a crime
reduction device for the protection of people.
This European Standard applies to a Security Fog Device that can be connected to an Intruder and
Hold-up Alarm System (I&HAS). It can assist insurers, intruder alarm companies, customers and the
police in understanding the principles and specifications of a Security Fog Device.
The purpose of a Security Fog Device 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 European Standard is not intended to cover standalone or mobile Security Fog Devices.
This European Standard has been designed to be flexible enough to encourage and encompass
future developments in the field of Security Fog Devices.
1 Scope
This document specifies the requirements for Security Fog Devices as part of an I&HAS. It covers
application and performance and also gives the necessary tests and trials to ensure efficiency and
reliability of such obscuration devices.
This document also gives guidance on the criteria for design, installation, operation and maintenance
of Security Fog Devices.

4 Environmental requirements
4.1 Environmental classification
The Security Fog Device shall meet Environmental Class II (Indoor – General: environmental
influences normally experienced indoors when the temperature is not well maintained) in accordance
with EN 50131-1.
4.2 Environmental tests
For all operation the SFD shall not activate, generate tamper, fault or other signals or messages when
subject to the specific range of environmental and EMC conditions and shall continue to function
normally and within the safety specifications of its components.
The following Class II level environmental tests from EN 50130-5:2011 shall be applicable when
testing the SFD:
— Clause 8: dry heat (operational);
— Clause 10: cold test (operational);
— Clause 14: damp heat, cyclic (operational);
— Clause 17: sulphur dioxide (SO2) (endurance);
— Clause 20: impact (operational);
— Clause 22: vibration sinusoidal (operational).
4.3 Immunity to electromagnetic interferences
Electromagnetic compatibility (immunity, operational) shall be assessed in accordance with
EN 50130-4.
4.4 IP/IK rating
All parts and consumables of the SFD shall be housed in an enclosure meeting the following
requirements:
— IP rating of IP20 or better;
— IK rating of IK08 or better.
5 Access levels
The access levels used in this standard shall be as stated in EN 50131-1:2006, 8.3.1.
6 Protection requirements
6.1 General
The SFD shall operate in a way that does not harm persons and other equipment in its vicinity.
6.2 Product safety
This standard does not specify product safety requirements. Such requirements can be found in
relevant product safety standards.
NOTE 1 If the SFD falls under the Low Voltage Directive (2014/35/EU), electrical safety requirements can be
found in EN 60065 or EN 60950-1.
NOTE 2 EN 60065 and EN 60950-1 are being replaced by EN 63268-1.
NOTE 3 The standards mentioned above cover both electrical and flammability hazards.
6.3 EMC
This standard does not specify EMC requirements. Such requirements can be found in relevant EMC
standards.
NOTE 1 Emission limits and test methods are defined in the generic standard EN 61000-6-3.
NOTE 2 Immunity requirements for components of fire, intruder, hold up, CCTV, access control and social
alarm systems are defined in EN 50130-4 (see also 4.3).
6.4 Non-toxicity
The manufacturer shall provide evidence that the consumable(s) and the emitted fog do not present a
health and safety hazard to persons in normal use within the manufacturer’s specified consumable
life-time.
The non-toxicity assessment shall be carried out by a laboratory accredited to EN ISO/IEC 17025 in
the relevant field and shall include the following minimum elements:
— identification of the substances present in the consumable (fog liquid) and in the emitted fog;
— bibliographical research;
— sampling and analysis of all pollutants (gaseous, aerosol liquid and airborne particles) that
contribute to the potential exposure as identified in the bibliographical research.
For that assessment, the laboratory shall use pollutant specific standards referenced in EN 482 or
EN ISO 16000-1.
The non-toxicity assessment shall be repeated after each modification to the SFD or to the
consumable that can affect the toxicity of the ejected/emitted fog. It is the manufacturer’s responsibility
to decide whether such a change in design or formulation has occurred.
6.5 Pressure vessels requirements
When SFD includes a pressure vessel as propelling gas container, the container and its accessories
shall be such that:
— Maximum working pressure ≤ 30 bar (3 MPa)
— “Ps x V” ≤ 50 bar.litre (5 MPa.dm )
— Minimum working temperature ≤ -10 °C, but ≥ -50 °C
— Maximum working temperature ≥ 75 °C, but ≤ 300 °C for steel containers and ≤ 100 °C for
aluminium containers
NOTE This means the pressurized container will be suitable for any working temperatures between -10 °C
and +75 °C.
The container shall also meet the applicable requirements specified in EN 286-1.
