scope:

This document 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. It gives test procedures for the systems used, as well as describing relevant, and critical, features of the installation and commissioning procedures needed to implement the calculated design in a building. It covers systems intended to protect means of escape such as stairwells, corridors and lobbies, as well as systems The systems incorporate smoke control components in accordance with the relevant Parts of EN 12101 and kits comprising these and possibly other components (see 3.1.18). This document gives requirements and methods for the evaluation of conformity for such kits.
