Fire resistance tests for non-loadbearing elements - Part 4: Curtain walling - Part configuration

This European Standard specifies a method for determining the fire resistance of parts of curtain walling and of the perimeter seal. It examines the fire resistance to internal and external fire exposure of: — the spandrel panel, i.e. downstand, upstand or a combination thereof, or — the perimeter seal, or — the fixing of the framing system (anchoring) used to attach the curtain walling to the floor element, or — combinations thereof.
