DIN EN 1364-5
Fire resistance tests for non-loadbearing elements - Part 5: Air transfer grilles; German version EN 1364-5:2017
Feuerwiderstandsprüfungen für nichttragende Bauteile - Teil 5: Lüftungsbausteine; Deutsche Fassung EN 1364-5:2017
Overview
This European Standard specifies a method for determining the fire resistance of air transfer grilles (ATG). It is applicable to air transfer grilles intended for installation in building components (typically walls, floors or ceilings). The orientation of the installation of the air transfer grille can be vertical or horizontal. The closing mechanism of the air transfer grille can come from expansion of material and/or from any mechanical or electrical closing device. This test method is valid for fire resistant or fire resistant and smoke control air transfer grilles. An additional test configuration is valid for fire resistant or fire resistant and smoke control air transfer grilles in applications where flame impingement is a risk during open state from start of fire (Annex A). This test method evaluates the behaviour of the air transfer grille when exposed to the standard fire curve described in EN 1363-1 and the standard pressure described in EN 1363-1. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes under fire conditions. Such phenomena are only to be noted in describing the general behaviour of test specimens during the test. This document has been prepared by CEN/TC 127 "Fire safety in buildings" (secretariat: BSI, United Kingdom). Working Committee NA 005-52-02 AA "Brandverhalten von Baustoffen und Bauteilen - Bauteile" ("Reaction to fire of building materials and building components - Building components") at DIN Standards Committee Building and Civil Engineering (NABau) is responsible for the German collaboration.
