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.

8 Production tests
8.1 General
In addition to any other scheme of quality control, extinguishing aerosol dispensers shall be tested
according to the production testing schemes of this sub clause.
8.2 Verification of strength
8.2.1 General
The integrity of each extinguishing aerosol dispenser shall be verified by one of the following methods.
Directive 75/324/EEC specifies that if 8.2.3 or 8.2.4 are used the test method shall be approved by a
competent authority.
NOTE Further information in bibliography [4] and [5].
8.2.2 Hot water bath method
Each extinguishing aerosol dispenser shall be fully immersed in water, which is maintained at 50 °C.
The extinguishing aerosol dispenser shall remain in the water bath long enough to allow the contents to
also reach 50 °C and therefore develop P(T ). The extinguishing aerosol dispenser shall then be
max
observed for a period of 15s, any extinguishing aerosol dispenser that deforms or show any sign of
leakage with bubbles shall be rejected (this does not satisfy the requirement of 8.6).
For each production cycle it shall be demonstrated that P(T ) is actually reached in a representative
max
test sample.
8.2.3 Hot final test method
Each extinguishing aerosol dispenser shall be warmed in such a way as to ensure that the contents are
at 50 °C and therefore develops the internal pressure P(T ). This pressure shall be maintained for a
max
minimum of 15 s, any extinguishing aerosol dispensers that deform shall be rejected.
Leaks shall be detected with the same precision as in the case of the hot water bath test.
8.2.4 Cold final test method
Prior to assembly, each body shall be subjected to test pressure in accordance with E.2. No permanent
deformation shall be detected.
8.3 Burst test
From every batch, bodies shall be selected at random in accordance with the sampling plan in Table 2
and shall be subjected to a burst pressure test in accordance with E.3.
The pressure at which each of the bodies bursts shall be greater than that calculated in 5.7.
Table 2 — Burst test sampling plan
Number of assemblies per Number of assemblies
batch N sampled
N ≤ 2 500 5
Each additional 2 500 5
If a body bursts at a pressure less than that calculated in 5.7, then the test shall be repeated with
another number of samples, randomly selected from the same batch in accordance with Table 2. If a
body from the second series of tests bursts below the pressure calculated in 5.7, then the whole batch
shall be rejected.
8.4 Crimped closures
8.4.1 During production, the first extinguishing aerosol dispenser produced from each batch of valves
or bodies and the first extinguishing aerosol dispenser produced from each crimping head each day,
shall be checked for conformity to 5.2.2 and the results recorded.
If this sample does not conform, a further sample, produced after any appropriate adjustments, shall be
checked.
Production shall not commence until a sample conforming to 5.2.2 has been tested.
8.4.2 If more than 2500 extinguishing aerosol dispensers are produced in a day, from a crimping
head, one extinguishing aerosol dispenser in every 2500 subsequently produced shall be tested; if one
fails to conform to 5.2.2 then checks to identify all faulty extinguishing aerosol dispensers shall be
made. All that do not conform to 5.2.2 shall be rejected and the procedure specified in 8.4.1 shall be
repeated.
A record of the measured dimensions shall be kept.
8.5 Discharge test
One extinguishing aerosol dispenser in every 2500 shall be fully discharged in the normal working
position with the valve fully opened. The discharge duration and percentage discharge shall be
recorded. If these extinguishing aerosol dispensers do not meet the requirements of 7.2 and 7.3, then 10
more extinguishing aerosol dispensers shall be tested, if any fail, the batch shall be rejected.
8.6 Leak test
Each extinguishing aerosol dispenser shall be submitted to a final inspection of the filled and
pressurized extinguishing aerosol dispenser, capable of detecting a leakage rate equivalent to a loss of
pressure of 5 % per annum. Products with a leakage rate greater than 5 % per annum shall be rejected.
NOTE Leak detection by means of tracer gas detection is a suitable test method.
9 Colour and marking of extinguishing aerosol dispensers
9.1 Colour
The extinguishing aerosol dispensers shall be coloured as follows:
— between 50 % and 70 % of the surface area of the extinguishing aerosol dispensing body shall be
red in the range RAL 3000 to RAL 3002 as specified in Farbregister RAL −841-GL;
— the remainder of the surface area, which will be an area of between 50 % and 30 % of the
extinguishing aerosol body shall be of colour to identify the classes of fires on which the aerosol

10 Sampling
Annex L provides an example of samples required for completion of testing.
Annex A
(normative)
Test conditions
A.1 Storing and temperature
Unless otherwise stated, store extinguishing aerosol dispensers for not less than 24 h at a temperature
of (22 ± 8) °C before tests are carried out and maintain them within this temperature range until tested.
Unless stated otherwise, the ambient temperature for carrying out the tests is 0 °C to 30 °C.
For the discharge performance tests of Annex F, Annex G and Annex H and the fire performance tests of
Annex I use extinguishing aerosol dispensers fitted with a protective cap or safety device.
A.2 Mechanical preparation
Hold the extinguishing aerosol dispenser in the vertical position and drop it vertically 500 times from a
height of (15 ± 1) mm at a frequency of (1 ± 0,02) Hz onto a rigid steel plate, of dimensions (300 ± 5)
mm square and (60 ± 1) mm thick. Store the extinguishing aerosol dispenser at a temperature (22 ± 8)
°C for not less than 24 h.
A.3 Pressure connection
