Table Notes
  1. 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.
  2. 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.
  3. 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—
    1. any material which does not comply with this Table is protected on all sides and edges from exposure to the air; and
    2. 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
    3. 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.

  4. 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—
    1. its manufacturer or distributor—
      1. as approved for use with the fabric to achieve the required indices; and
      2. 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
    2. the applicator as having been carried out in accordance with the manufacturer’s specification.
  5. Materials used in an entertainment venue must have a label affixed to a representative sample of each different material indicating, in legible characters—
    1. name of manufacturer; and
    2. trade name and description of material’s composition; and
    3. retardant treatment (if any), name of applicator and date of application; and
    4. 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
    5. approved methods of cleaning.
  6. A cinematograph screen must have a supporting frame of metal construction.
