This document gives guidance and requirements for the design and calculation methods, installation, acceptance testing, routine testing and maintenance for pressure differential systems (PDS).<\/p>\n

PDSs are 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 and to keep tenable conditions in escape and access routes depending on the application.<\/p>\n

It covers systems intended to protect means of escape e.g. staircases, corridors, lobbies, as well as systems intended to provide a protected firefighting bridgehead for the fire services.<\/p>\n

It provides details on the critical features and relevant procedures for the installation.<\/p>\n

It describes the commissioning procedures and acceptance testing criteria required to confirm that the calculated design is achieved in the building.<\/p>\n

This document gives complete rules, requirements and procedures to design PDS for buildings up to 60 m.<\/p>\n

For buildings taller than 60 m the same requirements are given (e.g. Table 1<\/span>), but additional calculations and verification methods are necessary. Requirements for such methods and verification are given in Annex D<\/span>, but the methods fall outside the scope of this document [e.g. Computational Fluid Dynamics (CFD)].<\/p>\n

Routine testing and maintenance requirements are also defined in the document.<\/p>\n

In the absence of national requirements and under expected ambient and outside conditions, the requirements in Table 1<\/span> are fulfilled by the PDS.<\/p>\n","protected":false},"excerpt":{"rendered":"
