Table Notes
- In a fire control room or fire-isolated stairway, a material used as an attachment or part of an attachment to a building element must, if combustible, be attached directly to a non-combustible substrate and not exceed 1 mm finished thickness.
- A material, other than one located within a fire-isolated exit or fire control room, may be covered on all faces by concrete or masonry not less than 50 mm thick, as an alternative to meeting the specified indices.
- In the case of a composite member or assembly, the member or assembly must be constructed so that when assembled as proposed in a building—
- any material which does not comply with this Table is protected on all sides and edges from exposure to the air; and
- the member or assembly, when tested in accordance with Specification 3, has Spread-of-Flame Index and Smoke-Developed Index not exceeding those prescribed in this Table; and
- the member or assembly retains the protection in position so that it prevents ignition of the material and continues to screen it from access to free air for a period of not less than 10 minutes.

- the member or assembly retains the protection in position so that it prevents ignition of the material and continues to screen it from access to free air for a period of not less than 10 minutes.
- Any fire-retardant coating used in an entertainment venue to make a material comply with a required Flammability Index, Spread-of-Flame Index or Smoke-Developed Index must be certified by—
- its manufacturer or distributor—
- as approved for use with the fabric to achieve the required indices; and
- to retain its retardancy effect after a minimum of 5 commercial dry cleaning or laundering operations carried out in accordance with AS 2001.5.4, Procedure 7A, using non-phosphate ECE reference detergent A (without optical brightener); and
- the applicator as having been carried out in accordance with the manufacturer’s specification.
- its manufacturer or distributor—
- Materials used in an entertainment venue must have a label affixed to a representative sample of each different material indicating, in legible characters—
- name of manufacturer; and
- trade name and description of material’s composition; and
- retardant treatment (if any), name of applicator and date of application; and
- AS 1530 Part 2 and/or AS/NZS 1530 Part 3 test number and its Flammability Index, Spread-of-Flame Index and Smoke-Developed Index; and
- approved methods of cleaning.
- A cinematograph screen must have a supporting frame of metal construction.
