This document (EN 16327:2014) has been prepared by Technical Committee CEN/TC 192 “Fire and rescue service equipment” (Secretariat: BSI, United Kingdom), Working Group WG 2 “Firefighting pumps” (Secretariat: DI
6、N, Germany). The responsible German body involved in its preparation was the Normenausschuss Feuerwehrwesen (Firefighting and Fire Protection Standards Committee), Working Committee NA 031-04-05 AA Feuerlschpumpen SpA zu CEN/TC 192/WG 2. This European Standard is based on the German Standard DIN 144
7、30. It describes systems installed in fire-fighting vehicles in order to improve the efficiency of fire-extinguishing processes. This is achieved by adding chemical solutions or foam concentrates under pressure to the water being delivered by the firefighting centrifugal pump. Compressed-air may be
8、injected in some cases to create the finished foam. Stationary systems and mobile or portable equipment operating independently are not within the scope of this standard. The aim of the systems described is to improve the adhesion, penetration and retention time of the fire-extinguishing agent on th
9、e burning material, thereby transferring more energy, and improving the cooling effect of the applied media. The object of using foams with fire-extinguishing agents is to increase the effective contact area of the foam solution and to improve the adhesion to non-horizontal surfaces of the burning m
10、aterial, thereby increasing the time period in which heat is effectively transferred. The legal status of this standard is as follows: This standard contains specifications meeting the essential requirements set out in the “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that
11、 are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a
12、 manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 7000 DIN ISO 7000 DIN EN 16327:2014-07 3 Amendmen
13、ts This standard differs from DIN 14430:2008-12 as follows: a) the national standard has been converted into a European Standard; b) the Foreword and Scope have been rendered more precise including information on environmental impact of fluorine-containing foam extinguishing agents; c) all reference
14、s to national standards have been deleted; d) terms and definitions have been revised and volume ratios have been aligned with DIN EN 1568; e) a list of significant hazards has been included in Clause 4; f) safety and performance requirements have been revised; g) the classification and designation
15、of compressed-air foam systems (CAFS) has been modified; h) Annex C “Sample of a compressed-air foam system (CAFS) operating range diagram” has been added; i) Annex D “Test procedure for finished CAFS Foam” has been added (in analogy with DIN EN 1568); j) Annex E “Technical CAFS diagrams” has been a
16、dded; k) the text of the standard has been revised in form and substance.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered
38、are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built a
39、ccording to the provisions of this type C standard. The present document describes systems installed in a fire-fighting vehicle in order to improve the efficiency of fire-extinguishing processes. This is achieved by adding chemical solutions or foam concentrates (hereinafter collectively called foam
40、 concentrates) under pressure to the water being delivered by the fire-fighting centrifugal pump. Compressed-air may be injected in some cases to create the finished foam. In addition to Class B fire-fighting operation, the described systems are used in Class A fire-fighting operation, with the aim
41、to improve the adhesion, penetration and retention time of the fire-extinguishing agent on the burning material, thereby transferring more energy, and improving the cooling effect of the applied media. The object of using foams with fire extinguishing agents is to increase the effective contact area
42、 of the foam solution and to improve the adhesion to non-horizontal surfaces of the burning material, thereby increasing the time period in which heat is effectively transferred. Another aim of the systems described is to improve, ease, and speed-up the use of foam concentrates during regular use in
43、 municipal or similar fire-fighting operations. The following principles can be considered for mixing foam concentrates to water for fire-fighting purpose, where a) and b) is not part of this standard: a) Venturi type inductors which create a vacuum to draw foam concentrate into the water stream. Th
44、ese inductors may be used as loose equipment, coupled into the hose line or permanently installed with a fire pump. A “Round the Pump” (RTP) system takes water from the pump discharge through a venturi device to draw foam concentrate into the pump- suction NOTE These mobile systems are subject of a
45、standard currently in preparation by CEN/TC 192/WG 8. An RTP system may be used in conjunction with a PPPS if the full flow capacity of a fire pump is delivered as solution, and the full flow pump capacity exceeds the performance of the PPPS. All discharges on a fire pump will provide solution once
46、an RTP is in operation. A RTP system will contaminate the fire pump and related installations with foam concentrate. b) Premix (also known as batch mix) is a concept used in certain applications, where a measured amount of foam concentrate is added to the water in the vehicle tank, each time the wat
47、er tank is filled. There is no special mixing technology used, the foam concentrate is simply poured into the water tank. This principle is typically used for seasonal fire- fighting operation (forest and wildland) where the equipment is flushed, serviced and stored away once the season is over. c)
48、Positive-pressure proportioning systems (PPPS) use a foam concentrate pump to inject the foam agent into the water stream at a pressure higher than the water pressure. A PPPS typically provides solution to designated discharges on a fire pump. The systems considered in this standard were originally designed as “Class A foam proportioners” to handle low injection rates and variable flows. However, they can be used with any other suitable foam concentrate. Recent developments on foam concentrates allow low injection rate
