EN 16327 Fire-fighting - Positive-pressure proportioning systems (PPPS) and compressed-air foam systems (CAFS) - This European Standard applies to systems which add a foam concentrate to the water discharged from a fire-fighting centrifugal pump either: a) by a positive-pressure proportioning system (PPPS) alone, or b) together with compressed-air by means of a compressed-air foam system (CAFS). 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. Permanently installed or fixed systems in buildings or structures are not covered by this European Standard. NOTE 1 This European Standard is intended to be used in conjunction with EN 1846–2 and EN 1846–3. This European Standard applies to the design, manufacture and operation of such systems. This European Standard deals with all significant hazards, hazardous situations and events relevant to PPPS and CAFS when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacture (see Clause 4). NOTE 2 Performance requirements are also given (see Clause 7). 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. For systems to be used at temperature outside this temperature range, the particular temperature range should be specified by the user and the manufacturer should determine by a risk assessment any need for additional precautions. 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 European Standard does not deal with special hazards arising from the particular conditions under which these systems are used, for example: c) handling of any equipment, devices etc. which are connected to the system or are joined to it (e.g. handling of branch pipes/nozzles and pressure hoses); a) events specific to the location where the system is set up (e.g. on public roads); f) decommissioning and disposal; g) operation without supervision; h) immunity against electromagnetic fields and electrostatic discharge. 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. NOTE 3 EN 1846–2 covers hazards arising from noise for the complete vehicle. This European Standard does not deal with hazards related to handling foam concentrates or contact with. NOTE 4 Additive installation is dealt with in EN 1846–3. This European Standard is not applicable to systems which are manufactured before the date of publication of this European Standard by CEN.
