The work of preparing International Standards is normally carried o
11、ut through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO c
12、ollaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different ap
13、proval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be th

18、ment Part 6: Vehicle mounted compressed air foam systems ISO 2016 All rights reserved v ISO 7076-6:2016(E) Introduction Compressed air foam systems (CAFS) complying with this part of ISO 7076 are installed in or used in conjunction with fire-fighting vehicles to improve the efficiency of fire-exting
19、uishing processes. Compressed air foam systems 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 foam. This is achieved by adding foam concentrates and compr
20、essed air, to be delivered into water under pressure by the fire-fighting pump, to the fire. Compressed air foam systems generate homogeneous foam that increases the effective contact area of the foam on the burning material, and improves the adhesion and penetration of the foam to non- horizontal s
21、urfaces of the burning material, thereby increasing the period in which heat is effectively transferred. It is assumed that systems defined in this part of ISO 7076 will only be operated by properly trained personnel. For CAFS to be used at a temperature outside this temperature range, the particula
22、r temperature range should be specified by the user and the manufacturer should determine by a risk assessment any need for additional precautions.vi ISO 2016 All rights reserved Fire protection Foam fire extinguishing systems Part 6: Vehicle mounted compressed air foam systems 1 Scope This part of
23、ISO 7076 specifies requirements for compressed air foam systems (CAFS) in which foam concentrate and compressed air are continuously added to the water being discharged from the fire- fighting pump. This part of ISO 7076 is applicable to CAFS that can be permanently installed in fire- fighting vehic
24、les, transportable, or mobile. This part of ISO 7076 specifies requirements for CAFS which are used at ambient temperatures ranging from 10 C to +40 C. This part of ISO 7076 does not apply to stationary CAFS. This part of ISO 7076 does not apply to requirements for hazards related to handling foam c
25、oncentrates, noise generated by CAFS, drives, auxiliary equipment, power sources, or pumps connected to the CAFS. This part of ISO 7076 does not specify requirements for special hazards arising from particular conditions under which CAFS are used, for example: immunity against electromagnetic fields
26、 and electrostatic discharge; operation without supervision; events specific to the location where the CAFS is set up (e.g. on public roads); handling of any equipment, devices, etc., which have to be connected to the CAFS or are joined to it (e.g. branch pipes, nozzles and pressure hoses); decommis
27、sioning and disposal. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、equirements of Clauses 4, 6 and 7, which shall be verified by visual inspection or engineering assessment, shall be tested as described in Clause 5 and shall meet the requirements of the tests (see Annex A for guidance on conducting the assessments). It is recognized that minor variations occur in t
42、he design of CAFS (e.g. to ensure compatibility with multiple truck types). Where minor variations occur and in the interests of economy, only one variant of each model need undergo type assessments. The CAFS should undergo new type assessments where a design change is likely to affect a requirement
43、 of this part of ISO 7076. The extent of the re-assessment can be limited, depending on the type of design change that has been made to the CAFS. In all cases, the manufacturer should maintain appropriate documentation. 4.1.2 Individual assessments In addition to the requirements of 4.1.1, each CAFS
44、 produced by the manufacturer shall meet the requirements of Table 1, which shall be verified by visual inspection, engineering assessment or test, and shall meet the requirements of the tests (see Annex A for guidance on conducting the assessments).
