Natural smoke and heat exhaust ventilation systems (NSHEVS) extract smoke gases in the event of fire, to ensure a smoke-free area at ground level and on escape routes. The devices used in a smoke and heat exhaust ventilation system are called "natural" if they work without an additional ventilation drive. Throughout Europe, NSHEVS are tested in accordance with the DIN EN 12101-2 standard.
