This document gives guidance for system designers, installers, commissioners and maintenance teams on the
incorporation of protective measures for air distribution systems including dual purpose systems for smoke
and heat exhaust systems within buildings, to prevent the initiation and the spread of fire, smoke and other byproducts
of combustion.
This document intends to only support any national (building) regulations, which are the basis of any design of
a building or parts of it. It is up to the designer to enquire about the suitability (in particular in legal terms) of a
specific solution given in this document (e.g. although “dual purpose systems” are covered in this document,
they may not be permitted in some Member States or only in certain types of buildings).
This document applies to all air distribution systems including dual purpose systems (except systems only
dedicated to smoke exhaust systems, which are dealt in other European standards) including technical rooms
or spaces for the installation of devices to assist in ventilation of a building (e.g. distance of storage of
combustible materials to devices and not the fire resistance of the building structure), penetrations, and
following components/products used in the system like:
inlet/outlet louvres;
fans not exposed / exposed to the smoke;
air control dampers;
ducts;
fire control dampers;
air terminal devices;
anchors and supports;
duct fittings;
control panels;
cables and connections;
air handling units;
air filters;
sound attenuators;
heat exchangers.
