Mobile fire extinguishers - Part 1: Characteristics, performance and test methods

This European Standard specifies the rules of design, type testing and inspection during manufacturing, ratings and classification of mobile fire extinguishers and test methods to be used. It applies to mobile fire extinguishers with a total mass above 20 kg for powder, water based and CO2 extinguishers. This standard applies to mobile fire extinguishers that are manoeuvred by an operator on foot only.
It does not cover fire tests for class C and class F fires, but the used extinguishing media can be effective on these types of fire. Class D fires are considered to be a very specialist application and are not included in this standard, but may be made the object of national specification.

Fahrbare Feuerlöscher - Teil 1: Eigenschaften, Löschleistung und Prüfungen

Diese Europäische Norm legt die Vorgaben im Hinblick auf die konstruktive Gestaltung, die Typprüfung und die Überprüfung während der Fertigung, die Leistungsdaten und die Klassifizierung von fahrbaren Feuerlöschern sowie das anzuwendende Prüfverfahren fest. Diese Norm gilt für fahrbare Feuerlöscher mit einer Gesamtmasse von mehr als 20 kg, ausgeführt als Pulver  Feuerlöscher, als Feuerlöscher mit wässrigem Löschmittel und als CO2 Feuerlöscher. Weiterhin gilt diese Norm nur für fahrbare Feuerlöscher, die durch eine sich zu Fuß fortbewegende Person bewegt werden.
Nicht erfasst werden Löschprüfungen der Brandklassen C und F, wobei jedoch die im Rahmen dieser Norm verwendeten Löschmittel für diese Brände effektiv sein können. Brände der Brandklasse D gelten als sehr spezielle Brände, die in dieser Norm nicht erfasst werden; für sie können jedoch nationale Vorschriften erstellt werden.

Extincteurs d'incendie mobiles - Partie 1 : Caractéristiques, performances et méthodes d'essai

La présente Norme européenne spécifie les règles de conception, les essais de type, les contrôles en cours
de production, les performances et la classification des extincteurs d’incendie mobiles ainsi que la méthode
d’essai à employer. Elle s’applique aux extincteurs d’incendie mobiles d’une masse totale supérieure à 20 kg
pour les extincteurs à poudre, à base d’eau et les extincteurs à CO2 La présente norme s’applique
uniquement aux extincteurs d’incendie mobiles manoeuvrés par un opérateur à pied.
Elle ne traite pas des essais de résistance au feu pour les feux de classes C et F, mais les agents extincteurs
utilisés peuvent être efficaces sur ces types de feux. Les feux de classe D sont considérés comme une
application très particulière et ne figurent pas dans la présente norme ; ils peuvent toutefois faire l’objet d’une
spécification nationale.

6.4 Retention of propellant 6.4.1 General Extinguishers and propellant containers shall be designed in such a way as to permit their retention of propellant to be verified at regular intervals. 6.4.2 Propellant container The mass and/or the pressure of the propellant gas shall be validated by weighing or by checking the pressure. All required information (type of propellant; nominal charge; tare weight) shall be permanently marked on the cylinder. 6.4.3 Stored pressure extinguishers 6.4.3.1 Water based and powder extinguishers It shall be possible to check the state of charge of stored pressure extinguishers by measuring the internal pressure. This shall be obtained by means of a connection to enable the internal pressure to be checked directly by an independent apparatus. Such a connection shall be fitted with a pressure retaining cap and shall communicate directly to the contents under pressure. A pressure indicator shall be fitted. 6.4.3.2 CO2 extinguishers The state of charge of CO2 extinguishers is checked by weighing. 6.4.4 Acceptance levels Leakage from an extinguisher, or propellant cartridge, shall not exceed the following for: a) stored pressure extinguishers a maximum pressure loss of 5 % per year measured at 20 °C; b) extinguishers and propellant cartridges tested by weighing, a rate of 5 % of the nominal charge per year;

EN 1866-1:2007 (E) 12 c) extinguishers, pressurised only at the moment of operation, between pressurization and opening of the control valve, the pressure loss shall be less than 1 % per minute. 6.5 Control valve Extinguishers shall be fitted with a control valve to enable the discharge to be temporarily interrupted. Furthermore, the valve shall be resistant to leakage following cessation of the emission. This shall be verified in accordance with A.5. The difference in pressure shall not be more than 20 %. The control valve with a nozzle must be situated at the end of the hose. 6.6 Working position In normal working position, the extinguishers with its nominal charge shall remain stable when the hose completely unrolled, is pulled with a force of 150 N. The direction of the force is applied under the least favourable condition. 6.7 Hose and coupling The length of the flexible section of the hose assembly shall be not less than 5 m. The hose and coupling system shall function throughout the operating temperature range, and coupling systems shall be designed and fitted in such a way that they cannot damage the hose. 6.8 Operation devices 6.8.1 General With the exception of safety devices to prevent inadvertent activation of the operating mechanism (see 6.8.3), the extinguisher shall have no components which need to be added or removed before use.

6.8.2 Operating and jet control mechanisms devices The activation of the extinguisher shall not depend upon the repetition of a given action on the same device. When measured in accordance with A.3 or A.4 as appropriate, the force or the energy required to activate the operating device(s) shall not be greater than the values laid down in Table 8 for the operating temperature range. Activation implies the totality of actions required for pressurisation (if the extinguisher is not permanently under pressure) and the initial release of the extinguishing media.

EN 1866-1:2007 (E) 13 Table 8 — Maximum force or energy of operation Maximum allowance Type of device Force in N Energy in J Operating lever and squeeze grip lever 200 - Valve wheel 100a - Strike knob - 2 a The force shall be measured at the outside edge of the wheel. 6.8.3 Safety devices The operating mechanism shall be provided with a safety device to prevent inadvertent operation. The release of the safety device shall involve an operation distinct from that of the operating mechanism, shall require a force between the limits of 20 N and 100 N and shall in no way affect the operation of the equipment. It shall be possible to determine whether the safety device has been operated, by means of a safety element, consisting for example of a metal wire and seal. This device shall be so constructed that any unaided manual attempt, using a force or impact equal to twice the relevant value in Table 8 to initiate discharge without first operating the safety device shall not deform or break any part of the mechanism in such a way as to prevent the subsequent discharge of the extinguisher. 6.8.4 Discharge from water based extinguishers The discharge from water based extinguishers shall be ensured as follows:  in case of a dip tube, it shall be made from materials resistant to the extinguishing agent;  discharge of the extinguishing media shall be through a filter, in order to retain foreign matter. This filter shall be placed upstream of the smallest section of the discharge passage. Each orifice of the filter shall have an area smaller than that of the smallest cross section of the discharge passage. The total area of the combined filter orifices shall be at least equal to eight times the smallest cross section of the discharge passage. This filter shall be accessible to facilitate maintenance. 6.8.5 Pressure gauge 6.8.5.1 General Powder and water based stored pressure extinguishers shall be provided with a pressure gauge. This pressure gauge shall be capable of being checked to ensure that it is in good working order by an independent apparatus which uses the application of pressure. 6.8.5.2 Requirements for the scale of pressure gauges The scale of the pressure gauge shall have:  zero zone (to indicate zero pressure). If there is an end stop for the moving pointer, this shall be on the negative pressure side of the zero zone. The pointer shall not contact the end stop at zero pressure;  green zone (working zone), covering pressures at temperatures over the range of operating temperatures (see 6.1.1). The scale of the pressure gauge shall be calibrated in bars.

EN 1866-1:2007 (E) 14 The zones at either side of the green zone shall be red. A diagram of the scale of the pressure gauge is shown in Figure 1. Errors in the pressure gauge calibration shall not exceed the f
