Fire Hazard Properties (Specs C1.10 & C1.10a) Print E-mail
The Building Code of Australia (BCA) regulates materials that are used in construction of Class 2 to 9 buildings (not single family homes). These are stipulated by "Specification C1.10".

In addition, the BCA regulates materials that are used for floor, wall and ceiling coverings separately in Class 2 to 9 buildings (not single family homes). These are stipulated by "Specification C1.10a".

The term that is used is Fire Hazard Properties and the reference clause in the BCA is "C1.10 Fire Hazard Properties".

The BCA requires any material or assembly used for flooring, floor covering and wall and ceiling lining materials to comply with Specification C1.10a. All other materials (i.e. whatever holds up the floor covering or lining) are required to comply with Specification C1.10.
(See: Specification C1.10: Materials & Assemblies)

Some products may require different specifications depending on use. An example of this is plywood flooring used on joists and bearers. The plywood is required to comply with Specification C1.10a when the plywood is the topmost layer, i.e. exposed plywood flooring. When it has a carpet, decorative timber or tiles etc over it, then the plywood is required to comply with Specification C1.10. The topmost layer of carpet or other floor covering is required to comply with Specification C1.10a as it is the covering.
(See: Specification C1.10a: Floor Coverings)

Similarly for walls, a lining such as timber linings or panels are required to comply with Specification C1.10a. The studs that are used to support the linings are required to comply with Specification C1.10.
(See: Specification C1.10a: Wall and Ceiling Linings)

The BCA exempts certain circumstances such as timber framed windows, timber hand rails or skirting, door skins, joinery, cupboards, shelving or similar. The BCA also exempts paint, varnish or lacquer or adhesives used.
