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.

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.

---------------------- Page: 13 ----------------------
SIST EN 50131-8:2019
EN 50131-8:2019 (E)

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.

In order to ensure adequate storage and transportation, the container shall be marked and labeled

according to Clause 12 of EN 286-1:1998. This includes (but is not limited to):
— the maximum working pressure (PS in bar);
— the maximum working temperature (T in °C);
max
— the minimum working temperature (T in °C);
min
— the capacity of the vessel (V in litres);
— the name, registered trade name/mark and the address of the manufacturer;
— the type and serial or batch identification of the container.
6.6 Labels and warnings

The labelling of the SFD and its consumables for transportation, storage and handling shall meet the

provisions of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).

NOTE Safety Data Sheets (SDS) in GHS format also comply with the European “CLP regulation” EC No

1272/2008 and its amendments.
6.7 Energy efficiency

Energy consumption of the SFD in idle mode shall be measured and the results included in the

documentation (see the testing procedure in Annex C).

The idle mode (as defined in 3.1.3) shall guarantee the generation of the maximum quantity of fog for

which the SFD is designed, in one shot, and within a time not longer than the maximum time required

in 7.1.
---------------------- Page: 14 ----------------------
SIST EN 50131-8:2019
EN 50131-8:2019 (E)
