AS 5113:2016 pdf free.Fire propagation testing and classification of external walls of buildings
Where cavity barriers are part of the external wall system, the specimen shall include cavity barriers installed in accordance with the design specification. Floor levels shall be assumed to occur 0.3 m and 3 m above the opening to establish the position of cavity barriers if the design specification defines the cavity barrier position relative to floor levels. Framing of the opening shall be representative of the intended installation.
If the external wall system to be classified comprises an inner leaf having the fire resistance levels specified by the National Construction Code (NCC) (but not less than -/30/30) and satisfying all other NCC fire related criteria for external walls and the external cladding is either directly fixed or fixed by means of a supporting framework, the test shall be performed with the cladding fixed to a representative wall system.
NOTE: A lightweight partition system faced with two 13 mm fire-rated plasterboard sheets may be used to represent the non-combustible inner leaf.
All of the following performance criteria shall be satisfied:
(a) Temperatures 4 m above the opening measured 10 mm from the exposed specimen face shall not exceed 600°C for a continuous period greater than 30 s.
(b) Temperatures at the mid-depth of each combustible layer or any cavity 4 m above the opening shall not exceed 250°C for a continuous period greater than 30 s.
(c) Where the system is attached to a wall that is not required to have an FRL of -/30/30 or 30/30/30 or more, the temperature on the unexposed face of the specimen 900 mm above the opening shall not exceed a 180 K rise. Five thermocouples equally spaced at 500 mm centres with insulating pads, fitted in accordance with the requirements of AS 1530.4 for the measurement of surface temperatures shall be used.
(d) Where the system is attached to wall that is not required to have an FRL of-/30/30 or 30/30/30 or more, flaming or the occurrence of openings in the unexposed face of the specimen above the opening shall not occur.
(e) Flame spread beyond the confines of the specimen in any direction, as determined during the post-test examination, shall not occur. The examination shall include flame damage such as melting, charring but not smoke discolouration or staining of the surface, any intermediate layers and the cavity.AS 5113 pdf free.
