of damper types, NAAD-22 provides guidance on minimum regulatory requirements for routine maintenance, testing and inspection of installed dampers. It also covers installation, testing and commissioning of dampers during initial installation, as well as considerations for the correct design Some key areas to study are the requirements relating to system design and damper selection, and the importance of detail and quality of workmanship during installation. Recognition is given that the required
knowledge may not be held by a single party, therefore, the involvement of a manufacturer at the early stage of design, who can support the Dutyholder with respect to the should be considered. In the case of a new build, once the building has been designed for compartmentalisation, and the damper is being selected, the type of supporting construction into which the damper is to be installed is crucial. The manufacturer must provide a Declaration of Performance (DoP) and Installation & Operating Manual Without both of these documents, there is no guarantee of performance that the installation will meet the
