26、n) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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 rep

27、resented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards a

28、re drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio

29、nal Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility 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 21927-9 was

30、prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 11, Smoke and heat control systems and components. ISO 21927 consists of the following parts, under the general title Smoke and heat control systems: Part 1: Specification for smoke barriers P

31、art 2: Specification for natural smoke and heat exhaust ventilators Part 3: Specification for powered smoke and heat exhaust ventilators Part 9: Specification for control equipment Part 10: Specification for power output devices BS ISO 21927-9:2012ISO 21927-9:2012(E) ISO 2012 All rights reserved vii

32、Introduction Smoke- and heat-control systems (SHCS) create and maintain smoke-free areas in a construction works by controlling smoke flow, thus improving the conditions for the safe escape and/or rescue of people and animals and the protection of property, and permit fire-fighting in the early stag

33、es of the fire. The use of smoke and heat exhaust ventilation systems (SHEVS) to create smoke-free areas beneath a buoyant smoke layer has become widespread. Their value in assisting in the evacuation of people from construction works, reducing fire damage and financial loss by preventing smoke logg

34、ing, facilitating fire fighting, reducing roof temperatures and retarding the lateral spread of fire, is firmly established. For these benefits to be obtained, it is essential that smoke and heat exhaust ventilators operate fully and reliably whenever called upon to do so during their installed life

35、 A heat and smoke exhaust ventilation system is a scheme of safety equipment intended to perform a positive role in a fire emergency. Components for any smoke and heat control system are installed as part of a properly designed system. Smoke and heat control systems help to: keep the escape and acc

36、ess routes free from smoke; facilitate fire fighting operations; delay and/or prevent flashover and thus full development of the fire; protect equipment and furnishings; reduce thermal effects on structural components during a fire; reduce damage caused by thermal decomposition products and hot gase

37、s. Pressure differential systems are used to either positively pressurize spaces separated from the fire or to depressurize the space containing the fire in order to limit or prevent the flow of smoke and heat into adjacent spaces. A typical use would be to pressurize an escape stairwell in order to

38、 protect vertical means of escape. Depending on the design of the system, natural or powered smoke and heat ventilators can be used in a smoke and heat control system. Control equipment (c.e.) is required to control all components in a SHCS, such as: natural ventilators; powered ventilators; smoke b

39、arriers; smoke dampers; air inlets. SHCS control equipment may also provide control for day-to-day ventilation and signals to other fire safety equipment under fire conditions. SHCS control equipment may be for extra-low-voltage or low-voltage electrical systems or pneumatic systems or any combinati

40、on of these. Power output devices for control equipment are dealt with in ISO 21927-10.
