Introduction
This European Standard describes the design and testing criteria for safety cabinets to be used in
laboratories to store flammable liquids in closed containers at normal room temperatures.
Primarily, this European Standard covers the three major safety requirements for storage of
flammable liquids, which are:
a) minimising the fire risks associated with the storage of flammable substances and protection of
the cabinet's contents in the event of fire for a known (tested) minimum length of time (fire rating);
b) minimising the amount of vapour released into the working environment;
c) retention of accidental spillage within the cabinet.
Testing of the cabinet [see a) above] under fire conditions is a normative part of the standard and the
procedures and interpretation of the tests are described in detail.
The fire test [see a) above] provides for four categories of fire protection / ratings. In practice the
degree of fire protection/rating allows the user to select, depending on individual circumstances, a
cabinet which will allow sufficient time for personnel to leave, and fire fighters to enter the laboratory
before it is likely to that the flammables stored turn a possible minor / extinguishable fire into an
uncontrollable one. The methods of achieving b) and c) above are sufficiently flexible to allow for
local/national needs.
Caution should be exercised when determining the appropriate cabinet fire rating when flammables
having auto-ignition temperatures below 200 °C and/or having high vapour pressures at room
temperature are involved. When such flammable materials are being stored, expert advice should be
sought.
1 Scope
This European Standard is a product specification, giving performance requirements for fire safety
cabinets to be used for the storage of flammable liquids in laboratories. It is applicable to cabinets
with a total internal volume of not greater than 1 m , which may be free standing, restrained to a wall
or mounted on wheels or castors. It is not applicable to brick enclosures or walk-in storage rooms.
This European Standard is not applicable to cabinets which do not take their weight on their base.
Requirements are given in respect of the construction of the cabinet and its capacity to resist fire
conditions on the outside. A classification of cabinets is given, according to the level of fire resistance
offered, and a type test is included, which draws on already existing fire resistance tests, such as
those given in ISO 834-1 [1] and EN 1363-1.
The tests described in this European Standard are type tests.
NOTE 1 This European Standard does not discriminate between different flammable liquids, which may have
considerably different physical properties. The suitability of the standard in respect of any given flammable liquid
should be ascertained by the user.
NOTE 2 Attention is drawn to national regulations which may apply with regard to the storage of flammable
liquids.

5 Construction
5.1 Fire protection
In the case of a fire, the cabinet shall assure that, for at least 15 min, the contents of the cabinet do
not contribute any additional risks or spread of fire.
5.2 Doors
5.2.1 The doors of the cabinet shall be fully self-closing from any position.
The closing time of the doors, from the time of door release, shall not exceed 20 s. The time for
closing doors from their completely open position or from the position given by a hold open feature
shall be measured with a stopwatch, at a temperature of (20 ± 5) °C.
If a hold-open feature is included, the doors shall close fully in the event of a temperature of
(50 ) °C being reached in the vicinity of the front of the cabinet. The temperature release sensor
-10
for this shall be positioned in freely circulating air, so that it can heat up rapidly.
5.2.2 The temperature release component of the closing device shall be confirmed as conforming
to the requirements specified in 5.2.1, by the manufacturer's declaration of conformity.
5.2.3 Doors and their surroundings shall be designed such that the risk of injuries by pinching is
minimised. To minimise injuries by closure of the doors, the static force shall not exceed 100 N
between the main closing edge and the counter closing edge.
5.2.4 It shall be possible to operate each door single-handedly.
5.2.5 If the doors are lockable, the locking device shall not compromise the self-closing
performance required in 5.2.1.
5.3 Side and back walls
The side and back walls of the cabinet shall be of the same thickness and comparable construction.
5.4 Ventilation
5.4.1 Cabinets shall be equipped with openings for inlet and exhaust air, enabli
