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.

The significant hazards are given in Table 1, which is based on the principles of EN ISO 12100:2010, Annex B. Also shown are the subclause references to the safety requirements and/or protective measures in this document, if applicable. When the present standard was compiled, it was assumed that: a) the systems are operated by properly trained personnel only; b) components not subject to particular requirements are: 1) designed according to standard engineering practice and calculation methods, including due consideration to all modes of failure; 2) designed to be mechanically robust; 3) made of materials with strength and quality meeting the requirements of this European Standard; 4) 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; SIST EN 16327:2014
5 Classification and designation 5.1 Classification and designation of positive-pressure proportioning systems (PPPS) Positive-pressure proportioning systems (PPPS) are classified according to the criteria shown in Table 2, whereby a dosage ratio of between 0fo % and 1 % is to be assumed in all cases. Table 2 – Classification of positive-pressure proportioning systems (PPPS) Short designation Guarantee point 1 nominal foam solution delivery rate at nominal dosage ratio of 1 % l/min Guarantee point 2 foam solution delivery rate at dosage ratio of 0fo % at least l/min PPPS 200 200 100 PPPS 400 400 100 PPPS 800 800 100 PPPS 1600 1600 200 PPPS 2400 2400 800 NOTE 1 The values stated for guarantee point 1 are minimum requirements. NOTE 2 The values stated for guarantee point 2 specifies the values above which foam concentrate is to be added. This ensures that an adequate dosage is achieved even for delivery rates lower than the nominal delivery rate (e.g. if only one nozzle/branch pipe is utilized). Positive-pressure proportioning systems (PPPS) which conform to this standard shall be designated as follows: a) long designation; b) number of this European standard EN 16327; c) short designation PPPS; d) additive dosage ratio range, SIST EN 16327:2014
5.2 Classification and designation of compressed-air foam systems (CAFS) Compressed-air foam systems (CAFS) are classified according to the criteria shown in Table 3 and by the positive-pressure proportioning system (PPPS) used in conjunction with them (see Table 2). Table 3 – Classification of compressed-air foam systems (CAFS) Short designation Guarantee point 1 Nominal foam solution delivery rate at nominal proportioning rate of 1 % l/min Guarantee point 2 Nominal air delivery rate at normal condition l/min CAFS 200 200 600 CAFS 400 400 1 200 CAFS 800 800 2 400 CAFS 1600 1 600 4 800 Where compressed-air foam systems with higher volume delivery rates are required, the manufacturer and the customer are to reach a special agreement on characteristics of these. The nominal air delivery rate from the compressor shall comply with Table 3. The nominal foam solution delivery rate shall be as required by the customer but at least it shall be possible to generate wet foam (see 3.4). NOTE See sample diagram showing the operating range of a compressed-air foam system (CAFS) in Annex C. Compressed-air foam systems (CAFS) conforming to this standard are to be designated as follows: a) long designation; b) number of this European standard EN 16327; SIST EN 16327:2014
In all cases, a positive-pressure proportioning system (PPPS) capable of achieving at least the foam solution delivery rate specified in Table 2 shall be used. 6 Safety requirements and/or protective measures 6.1 Safety requirements applying to all systems 6.1.1 General Conformity to all requirements shall be verified by the measures described (type test). In addition, each system put on the market shall meet the requirements of this document that are indicated by “(IND)” in the verification procedures (standing for individual test) before dispatch. NOTE A guideline for acceptance testing and inspection on delivery of a system is given in informative Annex A. The system shall still be in a working condition and in compliance with this standard after completion of the tests. Positive-pressure proportioning systems (PPPS) and compressed-air foam systems (CAFS) shall comply with the safety requirements and/or protective measures of this clause. In addition, the provisions of EN 1846-2 and EN 1846-3 also apply to positive-pressure proportioning systems and compressed-air foam systems permanently installed in fire-fighting vehicles. In addition, the systems shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards (e.g. sharp edges), which are not dealt with by this document. General requirements regarding electromagnetic compatibility (EMC) can be met by applying the corresponding clauses of EN oo012 (CISPR 12) on interference emissions, provided that the system is only powered by internal-combustion engines, or by applying the generic standards EN 61000-6-3 for interference emissions and EN 61000-6-2 for immunity to disturbance. In order to check whether all hazards of a system have been dealt with in this clause, the manufacturer should carry out a risk assessment for the system to determine any additional hazards not covered by this European Standard. When additional hazards are identified, it is the responsibility of the manufacturer to incorporate suitable protective measures to reduce the risk from these hazards to an acceptable level. In order to minimize the risks associated with operating and installing the system, information for user/operating instructions in accordance with Clause 9 shall be provided. SIST EN 16327:2014
