The work of preparing International
15、Standards is normally carried out 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, al
16、so take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committ
17、ees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the poss
18、ibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7240-10 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 3, Fire

27、DIS 19292, prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 1, Lifesaving and fire protection. A fire detection and fire alarm system is required to function satisfactorily, not only in the event of a fire, but also during and after exposure to conditions likely
28、 to be met in practice, such as corrosion, vibration, direct impact, indirect shock and electromagnetic interference. Some tests specified are intended to assess the performance of the fire detectors under such conditions. The performance of flame detectors is assessed from results obtained in speci
29、fic tests. This part of ISO 7240 is not intended to place any other restrictions on the design and construction of such flame detectors.

31、and performance criteria for point-type, resettable flame detectors that operate using radiation from a flame for use in fire detection systems installed in buildings. Additional requirements for flame detectors for use in marine applications are specified in Annex A. This part of ISO 7240 does not

44、al 3.5 sensitivity measure of the ability of a flame detector to detect fires NOTE Sensitivity is not necessarily directly related to the response point. 3.6 sensitivity adjustment any adjustment of the detector or of the alarm criteria within the supply and monitoring equipment that leads to a chan
