Omfang

This European Standard applies to systems in which a foam concentrate is added to the water being discharged from the fire-fighting centrifugal pump: a) by a positive-pressure foam proportioning system or b) together with compressed air by means of a compressed-air foam system. In both cases pressure is applied to the foam concentrate in order to permit continuous operation. Such systems are permanently installed in fire-fighting vehicles (or may be designed as mobile or portable devices, providing that they meet minimum safety and performance requirements). Stationary systems are not covered by this standard. This European Standard applies to the design, manufacturing and operation of such systems. This European Standard applies to systems which are used at ambient temperatures ranging from -15 °C to +35 °C as stated in EN 1846-3. NOTE The safety requirements and/or protective measures are specified in clause 4 and the performance requirements in clause 5. In both clauses, the specifications are supplemented by a description of the corresponding tests. Clause 6 describes the classifications. This European Standard does not apply to the technical safety requirements concerning the design and manufacturing of drives, auxiliary equipment, sources of energy or pumps. Furthermore, this standard does not deal with special hazards arising from the particular conditions under which these systems are used, for example: a) handling of any equipment, devices etc. which have to be connected to the system or are joined to it (e.g. handling of branch pipes/nozzles and pressure hoses); b) events specific to the location where the system is set up (e.g. on public roads); c) decommissioning and disposal; d) operation without supervision; e) immunity against electromagnetic fields and electrostatic discharge. Annex E contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this document, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk. Hazards relating to any kind of mechanical, electrical, hydraulic, pneumatic and other equipment dealt with by the respective standards for such equipment are not covered by the present standard. References to the relevant standards are made wherever such standards exist and whenever necessary. This European Standard does not deal with the hazards arising from noise. For hazards arising from noise of systems installed in vehicles see EN 1846-2 and EN 1846-3. For hazards arising from noise of mobile or portable systems see the relevant clauses in EN 14466. When the present standard was compiled, it was assumed that: a) the systems described will only be operated by properly trained personnel; b) components not subject to particular requirements: 1) are designed according to standard engineering practice and calculation methods, including due consideration to all modes of failure; 2) are designed to be mechanically robust; 3) are made of materials which are of suitable strength and quality; 4) are manufactured of flawless materials. c) no hazardous materials (e.g. asbestos) are used; d) components are kept in good condition in order to maintain the required characteristics; e) the structural dimensions of load-bearing elements ensure safe operation and remain fully operational even after testing; f) fault-free operational functioning of the system is ensured within the specified ambient temperature ranges; g) manufacturers and operators of the system have agreed upon the system’s characteristics and operating conditions. This European Standard is not applicable to systems which are manufactured before the date of publication of this European Standard by CEN.
