AS 5113:2016 Classification of external walls of buildings based on reaction-to-fire performance
Standards Australia
This Standard incorporates Amendment No. 1 (September 2018). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.
After consultation with stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Australian Standard rather than an Australian/New Zealand Standard.
The objective of this Standard is to provide procedures and criteria for the classification of external walls of buildings according to their tendency to limit the spread of fire via the external wall and between adjacent buildings and limit falling debris that could be hazardous to evacuating occupants and fire fighters.
Further information on the relationship of this standard with the National Construction Code is provided in Appendix A.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
First published as AS5113:2016. Reissued incorporating Amendment No. 1 (September 2018).
This Standard sets out the procedures and criteria for the classification of external walls of buildings according to their tendency to spread fire—
(a) via the external wall;
(b) between adjacent buildings;
and production of falling debris that could be hazardous to evacuating occupants and fire fighters.
This Standard is applicable to all external vertical or near vertical surfaces and covers all types of external wall systems, including façades, outer skins, core materials, cavities and
attachments.
This Standard does not address the fire resistance and load bearing capacity of external walls, the fire hazard properties of internal surfaces or the impact of construction on the fire
severity of a fire occurring within a building.
