What is BS EN 1364-3 - Fire resistance tests for curtain walling about?
BS EN 1364-3 is the third part of the multiple series that specifies a method for determining the fire resistance of curtain walling – full configuration. BS EN 1364-3 is used in conjunction with EN 1363-1.
Note 1: BS EN 1364-3 does not cover double skin façades, over-cladding systems and ventilated façade systems on external walls.
Note 2: BS EN 1364-3 does not deal with the reaction to fire behavior of curtain walling.
Note 3: 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.

Why should you use BS EN 1364-3 - Fire resistance tests for curtain walling?
The fire resistance of curtain walling is determined under internal or external exposure conditions. In the latter case, the external fire exposure curve given in EN 1363-2 is used, subject to deviating national regulations.
BS EN 1364-3 test method is applicable to curtain walling type B i.e., fire-resistant glazing outside the spandrel area - fully fire-resistant curtain walling. For vertical linear gap seals, BS EN 1364-3 defines testing on individual sections of a curtain walling (for example, the perimeter seal, infill panel, or fixing of the frame system (anchoring) used to attach the curtain walling to the floor element.
Overall, BS EN 1364-3 will assist you in protecting yourself in the event of a fire hazard.
