EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 1364-5 testing. This European standard specifies a method for determining the fire resistance of air transfer grilles (ATG).
It can be applied to air transfer grilles intended to be mounted on building components (typically walls, floors or ceilings). The mounting direction of the air transfer grille can be vertical or horizontal.
The closing mechanism of the air transfer grille can come from material expansion or any mechanical or electrical closing device. This test method is applicable to fire resistant or fire resistant and smoke controlled air transfer grilles.
An additional test configuration applies to fire resistant or fire resistant and smoke controlled air transfer grilles in applications where there is a risk of flame impingement from the onset of the fire.
This test method evaluates the behavior of the air transfer grille when subjected to the standard fire curve described in EN 1363-1 and the standard pressure described in EN 1363-1. The purpose of this test is not to provide quantitative information on the leak rate of smoke or hot gases, or the transmission or generation of fumes under fire conditions. Such phenomena should only be noted when describing the general behavior of test specimens during testing.
Smoke leakage rate at ambient temperature or 200°C as an optional requirement for ATG with declared smoke control will be certified according to standard EN 1634-3.
Since ATG is considered a separating element, this test method is not applicable to determine the fire resistance of air transfer grilles used in ducts. The test method for ATG used in channels is described in the relevant channel standards.
This test method is not applicable to determining the fire resistance of a fire damper or a fire barrier connected to a duct because an ATG is tested as a fire separator on its own. Fire dampers are tested according to EN 1366-2. Non-mechanical fire barriers are tested according to EN 1366-12.
This test method is not applicable for determining the fire resistance of air transfer grilles in fire doors, shutters and opening windows specified in EN 1634-1 and EN 1364-2 due to deformation of fire doors, shutters and openable windows under fire conditions.
