EN 12101-2:2017 (E) 5 European foreword This document (EN 12101-2:2017) has been prepared by Technical Committee CEN/TC 191 “Fixed firefighting systems”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2017, and conflicting national standards shall be withdrawn at the latest by December 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12101-2:2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. This European Standard is one of the parts of the European Standard EN 12101 covering smoke and heat control systems. This European Standard has the general title Smoke and heat control systems and currently consists of the following parts: — Part 1: Specification for smoke barriers; — Part 2: Natural smoke and heat exhaust ventilators [the present document]; — Part 3: Specification for powered smoke and heat exhaust ventilators; — Part 4: Installed SHEVS systems for smoke and heat ventilation [Technical Report CEN/TR 12101-4]; — Part 5: Guidelines on functional recommendations and calculation methods for smoke and heat exhaust ventilation systems [Technical Report CEN/TR 12101-5]; — Part 6: Specification for pressure differential systems – Kits; — Part 7: Smoke control sections; — Part 8: Smoke control dampers; — Part 10: Power supplies. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 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 smoke. 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, reducing 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 exhaust 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 fire emergency. SIST EN 12101-2:2017



EN 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 natural 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.
