18、 BSI. This document has the general title Fixed fire-fighting systems Condensed aerosol extinguishing systems and will consist of the following parts: Part 1: Requirements and test methods for components; Part 2: Design, installation and maintenance. PD CEN/TR 15276-1:2009 CEN/TR 15276-1:2009 (E) 5

19、Introduction It has been assumed in the preparation of this document that the execution of its provisions is entrusted to appropriately qualified and experienced people in the specification, design, installation, testing, approval, inspection, operation and maintenance of systems and equipment, for

20、whose guidance it has been prepared, and who can be expected to exercise a duty of care to avoid unnecessary release of extinguishant. Product certification: Users of this document are advised to consider the desirability of independent certification of product conformity with this document based on

21、 testing and continuing surveillance, which may be coupled with assessment of manufacturer quality systems against EN ISO 9001. Fire-fighting systems covered in this document are designed to provide a supply of fixed condensed aerosol extinguishing medium to extinguish fire. The requirements of this

22、 document are made in the light of the best technical data known to the working group at the time of writing but, since a wide field is covered, it has been impracticable to consider every possible factor or circumstance that might affect implementation of the requirements. It is important that the

23、fire protection of a building or plant be considered as a whole. Aerosol extinguishant systems form only a part, though an important part, of the available facilities, but it should not be assumed that their adoption necessarily removes the need to consider supplementary measures, such as the provis

24、ion of portable fire extinguishers or other mobile appliances for first aid or emergency use, or to deal with special hazards. Aerosol extinguishants have been recognized as effective media for the extinction of Class A fires (solid surface burning fires) and Class B and Class C fires according to E

25、N 2, but it should not be forgotten, in the planning of comprehensive schemes, that there may be hazards for which these mediums are not suitable, or that in certain circumstances or situations there may be dangers in their use requiring special precautions. Advice on these matters can be obtained f

26、rom the appropriate manufacturer of the aerosol generators or the extinguishing system. Information may also be sought from the appropriate fire authority, the health and safety authorities and insurers. In addition, reference should be made as necessary to other national standards and statutory reg

27、ulations. It is essential that fire-fighting equipment be carefully maintained to ensure instant readiness when required. Routine maintenance is liable to be overlooked or given insufficient attention by the owner of the system. It is, however, neglected at peril to the lives of occupants of the pre

28、mises and at the risk of crippling financial loss. The importance of maintenance cannot be too highly emphasised. Condensed aerosol may contain traces of toxic substances like those produced by a fire, and will obscure vision like smoke from fire. PD CEN/TR 15276-1:2009 CEN/TR 15276-1:2009 (E) 6 1 S

29、cope This document specifies requirements, describes test methods for condensed aerosol extinguishing components and covers solely condensed aerosols. This document is not intended to indicate approval of the extinguishants listed herein by the appropriate authorities, as other extinguishants may be

30、 equally acceptable. This document is intended as a standard covering solely condensed aerosol. The condensed aerosol generator typically consists of the following main components: a) solid aerosol-forming compound; b) cooling mechanism; c) ignition device(s); d) end plate discharge outlet(s); e) ho

31、using; f) mounting bracket. This document does not cover dispersed aerosols. This document requires, as a precaution, that the room is evacuated and sealed off whenever a generator is activated. Precautions include evacuation of the proximity area, criteria for re-entering and other safeguards as st
