Portable aerosol dispensers for fire extinguishing purposes

This draft European Standard specifies the characteristics, performance and test methods for extinguishing aerosol dispensers, in accordance with Directive 75/324/EEC, for fire extinguishing purposes. Requirements in this draft Standard are specified for products containing less than 1 kg or 1 l of extinguishing media, which can be expelled by the action of internal pressure and are intended to extinguish test fires of type A + B, or type A + F, or type A + B + F classes of EN 2. These extinguishing aerosol dispensers are intended to be used by untrained persons for domestic applications. They are not intended to be used on gas fires (class C) and metal fires (class D).
Requirements are specified for minimum performance in Annex I for extinguishing test fires of type A, type B and type F classes of EN 2, as appropriate.
Annex A gives the conditioning treatment to be applied to extinguishing aerosol dispensers prior to testing as described in Annex B to Annex K.

Introduction

This document has been written with the aim of producing a specification for small disposable, aerosol

dispensers for fire extinguishing purposes with an acceptable level of performance. This type of product

is intended for domestic use only in situations where fires of limited proportions are anticipated

because of the nature of some process or activity, where the possibility of fire spreading to other

materials is remote, or where people are present at the likely times of risk. These products are not

intended to supplant extinguishers that comply with EN 3.

Special attention is drawn to Directive 75/324/EEC of 20 May 1975, on the approximation of the laws

of the member states relating to Aerosol Dispensers, Directive 2008/47/EC and Commission Directive

94/1/EC of 6 January 1994 adapting some technicalities of Council Directive 75/324/EEC on the

approximation of the laws of the Member States relating to aerosol dispensers.

1 Scope

This document specifies the requirements for non-refillable portable aerosol dispensers for fire

extinguishing purposes.

It supplements the characteristics, performance and test methods for extinguishing aerosol dispensers

for fire extinguishing purposes, in addition to the requirements of the Directive 75/324/EEC.

Requirements in this document are specified for products containing less than 1 kg or 1 l of

extinguishing media, which can be expelled by the action of internal pressure and are intended to

extinguish test fires of type A + B, or type A + F, or type A + B + F classes of EN 2. These extinguishing

aerosol dispensers are intended to be used by untrained persons for domestic applications. They are

not intended to be used on gas fires (class C) and metal fires (class D).

Requirements are specified for minimum performance in Annex I for extinguishing test fires of type A,

type B and type F classes of EN 2, as appropriate.

Annex A gives the conditioning to be applied to extinguishing aerosol dispensers prior to testing as

described in Annex B to Annex K.

— when the extinguishing aerosol dispenser is tested in accordance with G.1 each duration of

operation at (20 ± 10) °C shall be within ± 25 % with a maximum deviation of 5 s of the average

value determined in 7.2;
— the extinguishing aerosol dispenser shall fulfill the requirements of 5.7.
5.3.3 Chemical and pressure stability

The contents shall not generate pressure by reacting with the body or any lining. The complete

assembly shall be chemically stable. Small increases are permitted, but the total pressure may increase

min of being subjected to the tests in Annex C. The discharge time shall be ± 25 % with a maximum

deviation of 5 s of the actual time measured in 7.2 and the minimum discharge shall be in accordance

with 7.3.
5.5 Resistance to shock and mechanical damage

After being subjected to testing in accordance with Annex D, the extinguishing aerosol dispenser (with

safety device) shall operate as intended i.e. the discharge time shall be ± 25 % with a maximum

deviation of 5 s of the average effective discharge time measured in 7.2 and the minimum discharge

shall be in accordance with 7.3.

NOTE Disposal might be controlled by National laws and regulations.
5.9 Dielectric test
5.9.1 General

The dielectric test is designed to determine the electrical conductivity of the water based extinguishing

aerosol dispenser discharge stream during the test when performed in accordance with Annex J.

5.9.2 Required performance

When the extinguishing aerosol dispenser is in operation and the metallic plate is live, the current

between the aerosol dispenser and earth, and between the nozzle and earth, shall not be more than

0,5 mA at any time during the complete discharge of the extinguishing aerosol dispenser. The test shall

be carried out in accordance with Annex J.
