BS EN 14470-1:2004 – Fire safety storage cabinets — Part 1: Safety storage cabinets for flammable liquids

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 3 , which may be free standing, restrained to a wall with a total internal volume of not greater than 1 m 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.
2 Normative references

These normative references are cited at the appropriate places in the text, and the publications are listed hereafter.

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN ISO 13943:2000 and the following apply.
3.1
type
specimen of a design manufactured with the characteristics intended for series production
3.2
type testing
conformity testing on the basis of one or more specimens of product representative of the production
4 Classification
A fire safety storage cabinet shall be classified as one of the Types listed in Table 1.
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 0 (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.
