Australasian Regulatory Requirements Australia The technical provision relating to Building Control have been consolidated Nationally in Australia under the Building Code of Australia (BCA), which has been in all States & Territories through their respective Building Control related legislation. The Australian Building Codes Board, ABCB, currently maintains the BCA. New Zealand The introduction of the Building Act in New Zealand in 1991 consolidated a wide range of previous building-related legislation and also established the Building Industry Authority (BIA), who administers the New Zealand Building Code (NZBC). The various clauses of the performance-based NZBC can be met by satisfying the requirements of the prespective BIA Acceptable Solution, or by a performance-based Alternative Solution. Australian Reaction to fire requirements The reaction to fire requirements for wall and ceiling lining materials contained within the BCA have recently been reviewed and a new Specification C1.10a has been introduced to run in parallel for a grace period of 2 years (expiring July 1 st 2005) with existing Specification C1.10 The previous requirements, contained within BCA Specification C1.10, utilize the Spread-of-Flame, Smoke Developed and Flammability Indices of a material determined by testing the material in accordance with the small-scale reaction to fire test, Australian Standard AS1530.3 - “Simultaneous determination of ignitability, flame propagation, heat release and smoke release”. This small-scale reaction to fire test standard sets out a test method for the assessment of materials and components according to their tendency to ignite and propagate flame, the heat they release once ignition has occurred, and their tendency to release smoke. fastening of the panels. A relatively new ISO test method has been developed, ISO 13784 Part 1 which is a so called “free-standing set up”, based on the basic principles of ISO 9705, but catering for the exacting requirements of testing insulted (sandwich) panels. This test method was developed after some pioneering work conducted by Patrik Johansson and Patrick Van Hees of SP Swedish National Testing and Research Institute. New Zealand Reaction to Fire Requirements Under prespective Acceptable Solution (C/AS1) for the Fire Safety clauses of the NZBC, all formed plastic materials forming part of the wall, ceiling or roof system must be protected from ignition. Depending on the application of the sandwich panel with a foamed plastic core, this protection from ignition is achieved by either satisfying the fl ame propagation criteria of AS1366.3, the nominated spread of fl ame index and smoke development index criteria tested under AS1530.3, or passing a ten minute fl ame barrier test in accordance with AS1530.4. In other situations, depending on building height, distance to relevant boundary and building occupancy, C/AS1 requires that external cladding materials meet nominated performance criteria when tested to AS/NZS3837. Reaction To Fire Testing Standards AS1530.3 Full title: AS1530-Methods of Test On Building Material, Components and Structures - Part 3- Simultaneous Determination of Ignitability,Flame Propogation, Heat Release and Smoke Release. This standard is small scale fire test that provides reaction to fire test results for the ease of ignitability, flame propagation, heat and smoke release and provides data as 4 discrete indices. Under the new requirements contained in Specification C1.10a, reaction to fire testing requirements will require either a full-scale test, ISO 9705, (Full-scale room test for surface products), or in some special cases allow the use of fire testing at a smaller scale, accordingly using the cone calorimeter test apparatus defined in fire test standard, AS/NZS3837. The ISO 9705 full-scale test method may not in fact be the best test method for testing of insulating (sandwich) panels, as the test does not cater fully for the mechanical behaviour of the panels, such as the important influence on performance by way of the proprietary and relatively complex panel to panel joint systems, and the proprietary mechanical Figure 8: AS1530.3 tests on fi re retardant thatch.

This fire test method when applied to wall and ceiling linings is being made redundant in the Building Code of Australia and is being replaced by ISO9705 and/or AS/NZS3837 fire test data.

AS/NZS3837 Full Title: AS/NZS3837 - Joint Australian and New Zealand Standard - Method of test for heat and smoke release rates for materials and products using an oxygen consumption calorimeter. This is small scale reaction to fire test used for wall and ceiling linings. It is one of the two new fire test options for determing the new Building Code of Australia Group Number for wall and ceiling lining materials and in its own right, or alternatively using the ISO9705 full scale testing depending on the product type, replaces the previous small scale reaction to fire test requirements of AS1530.3 contained in the Building Code of Australia. Refer to figure 6 on page 10. ISO 9705 - “Room Corner Test” Full title: Fire tests - Full-scale room test for surface products. The ISO9705, Full-scale room test for surface products, consists of a non-combustible test room of given dimensions, with an open doorway. This room is lined with the product under test, by fixing the product onto the non-combustible walls. A fire, of known size is ignited in one corner and the corresponding heat release and smoke production rates are measured. The schematic of the reaction to fire test configuration is shown as Figure 2 and actual photos of products under test are shown in Figures 3 to 10.
