scope:

This European Standard specifies a method for determining the fire resistance of parts of curtain walling incorporating non-fire-resistant infilling product, e.g. glazing. It examines the fire resistance to internal and external fire exposure of: - spandrels, including downstand, upstand or the combinations thereof, - the horizontal linear gap seal and - the fixings used to attach the curtain walling to the floor element. The test method includes an assessment regarding falling parts that are liable to cause personal injury. This standard can also be used to determine fire resistance of parts of curtain walling to increase the field of application when previously tested to EN 1364-3.
