BS EN 1364-5:2026

This standard BS EN 1364-5:2026 Fire resistance tests for non-loadbearing elements is classified in these ICS categories:

• 13.220.50 Fire-resistance of building materials and elements
• 91.060.99 Other elements of buildings

This document 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 document is applicable to 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 (see Annex A). This document evaluates the behaviour of the air transfer grille when exposed to the heating 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 noted in describing the general behaviour of test specimens during the test. The determination of the rate of leakage of smoke at ambient temperature or at 200 °C as an optional requirement for ATG with declared smoke control is specified in EN 1634 3. This document is not applicable to the determination of the fire resistance of air transfer grilles that are used in ducts because ATG are considered as separating elements. The test method for ATG used in ducts is described in the corresponding duct standards. This document is not applicable to the determination of the fire resistance of a fire damper or a fire barrier connected to a duct one or both sides, as an ATG is tested as a fire-separating element on its own. Fire dampers are tested according to EN 1366 2. Non-mechanical fire barriers are tested according to EN 1366 12. This document is not applicable to the determination of the fire resistance of air transfer grilles in fire doors, shutters and openable windows as specified in EN 1634 1 and EN 1364 2, because the deformation of fire doors, shutters and openable windows in fire conditions differs from the deformation of flexible/rigid walls. Moreover, the location of thermocouples in the door standard is too specific to be handled in this document. All values given in this document are nominal unless otherwise specified.
