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.

    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 A2.4, has a Spread-of-Flame Index and a 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 subject to (a), (b) or (c) comply with a required Flammability Index, Spread-of-Flame Index or Smoke-Developed Index must be certified by—
    1. its manufacturer or distributor—
