BS EN 12101-2:2017EN 12101-2:2017 (E) 6 Introduction In a fire situation, smoke and heat exhaust ventilation systems create and maintain a smoke free layer above the floor by removing smok

36、e. They also serve simultaneously to exhaust hot gases released by a fire in the developing stages. The use of such systems to create smoke-free areas beneath a buoyant layer has become widespread. Their value in assisting in the evacuation of people from buildings and other construction works, redu

37、cing fire damage and financial loss by preventing smoke damage, facilitating access for firefighting by improving visibility, reducing roof temperatures and retarding the lateral spread of fire is firmly established. For these benefits to be obtained it is essential that natural smoke and heat exhau

38、st ventilators (referred to in this standard as NSHEV) operate fully and reliably whenever called upon to do so during their installed life. A smoke and heat exhaust ventilation system (referred to in this standard as a SHEVS) is a system of safety equipment intended to perform a positive role in a

39、fire emergency. BS EN 12101-2:2017EN 12101-2:2017 (E) 7 1 Scope This European Standard applies to natural smoke and heat exhaust ventilators (NSHEV) operating as part of smoke and heat exhaust systems (SHEVS), placed on the market. This standard specifies requirements and gives test methods for natu

40、ral smoke and heat exhaust ventilators which are intended to be installed in smoke and heat control systems in buildings. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
