Schedule 3 Definitions
Definitions
Note: States and Territories may vary or add to the definitions contained in Schedule 3 at the relevant State or Territory Appendix.
In the NCC unless the contrary intention appears—
- an organisation accredited by the National Association of Testing Authorities (NATA) to undertake the relevant tests; or
- an organisation outside Australia accredited to undertake the relevant tests by an authority recognised by NATA through a mutual recognition agreement; or
- an organisation recognised as being an Accredited Testing Laboratory under legislation at the time the test was undertaken.
Explanatory information:
This term is used to articulate whether the height of a room or space is sufficient and by what degree. This is achieved by having regard to the room or space's intended use by occupants, through consideration of the defined terms 'activity traits' and 'occupant traits'.
Explanatory information:
This term is used to describe the characteristics of the activities that will be undertaken in a room or space.
For example, the activities likely to be undertaken in a bedroom, and the associated features are—
- sleeping — a person laying horizontally; and
- resting — a person laying horizontally or sitting upright on the bed; and
- leisure activities, such as reading a book — a person sitting upright on the bed, with enough space to stretch their arms vertically; and
- dressing/changing clothes — a person standing with enough space to stretch their arms vertically.
- cools or heats cold or hot rooms; or
- maintains specialised conditions for equipment or processes, where this is the main purpose of the service.
- likely to be subject to significant snowfalls; and
- in New South Wales, A.C.T. or Victoria more than 1200 m above the Australian Height Datum; and
- in Tasmania more than 900 m above the Australian Height Datum.
Note:
This map is approximate only and altitude above Australian Height Datum must be used to determine whether the building falls into an alpine area region.

Explanatory information:
Alpine areas are located in New South Wales, Victoria and Tasmania.
Alpine areas are areas 1200 m or more above Australian Height Datum (AHD) for New South Wales, Australian Capital Territory and Victoria, and 900 m or more above AHD for Tasmania, as shown in Figure 1.
Alpine areas are considered to receive significant snowfalls (snowfalls that result in an average snow accumulation on the ground of 175 mm or greater). Regions in New South Wales, the Australian Capital Territory and Victoria between 600–1200 m AHD are considered to be sub- alpine areas and may receive significant snowfalls, however unlike alpine areas the snow is unlikely to accumulate.
It is recommended that the appropriate authority be consulted to determine whether the building is located in an alpine area . AS/NZS 1170.3 also contains further detail in the identification of alpine areas and the altitude of the alpine regions of Australia.
In the Australian Capital Territory, Canberra is not designated as an alpine area as snow loads are not considered significant.

Resistance to the incipient spread of fire refers to the ability of a ceiling to prevent the spread of fire and thermally insulate the space between the ceiling and the roof or floor above. "Resistance to the incipient spread of fire" is superior to "fire-resistance" because it requires a higher standard of heat insulation.
The definition is used in Volume Two for separating floors/ceilings for a Class 1a dwelling located above a non-appurtenant private garage.
