Smoke and heat control systems - Specification for pressure differential systems. Kits Ingestion-build-117251 This British Standard is theThis European Standard, a part of the BS EN 12101 series, specifies pressure differential systems designed to hold back smoke at a leaky physical barrier in a building, such as a door (either open or closed) or other similarly restricted openings. It covers methods for calculating the parameters of pressure differential smoke control systems as part of the design procedure. BS EN 12101 6: 2005 gives test procedures for the systems used, as well as
