ÖNORM EN 1364-3

This European Standard specifies a method for determining the fire resistance of curtain walling - full configuration. This European Standard is used in conjunction with EN 1363-1. The test method is applicable to curtain walling type B. The test is not appropriate for testing curtain walling type A. The fire resistance of curtain walling may be determined under internal or external exposure conditions. In the latter case the external fire exposure curve given in EN 1363-2 may be used, subject to deviating national regulations. Tests on individual parts of a curtain walling (e.g. perimeter seal, infill panel or fixing of the framing system (anchoring) used to attach the curtain walling to the floor element) or systems with fire resistance requirements only to the spandrel area may be performed using EN 1364-4. For vertical linear gap seals, this part of the standard applies. This European Standard does not cover double skin façades, over-cladding systems and ventilated façade systems on external walls. It does not deal with the reaction to fire behaviour of curtain walling. This standard is intended to be read in conjunction with EN 1363-1 and EN 1363-2.
