When tested independently (tests 7 to 10 in Table 3-4), the test results obtained for each AS1530.3 index (Ignitability, Spread of Flame, Heat Evolved and Smoke Developed) are almost identical with only a small variance in the Smoke Developed Index. In all cases, the AS1530.3 results are within the following value range:Ignitability Index: 0 Spread of Flame Index: 0 Heat Evolved Index: 0 Smoke Developed Index: 0-3 When the AS1530.3 test is repeated with the steel facings bonded either side of a material deemed not combustible under AS1530.1, in this case mineral wool (tests 1, 2 & 3 in Table 3-4), the results give a near identical outcome to tests 7 to 10 in Table 3-4, that is: Ignitability Index: 0 Spread of Flame Index: 0 Heat Evolved Index: 0 Smoke Developed Index: 2-3 Similarly, when the AS1530.3 test is repeated with the steel facings bonded either side of a combustible EPS-FR core material (tests 4 and 5 in Table 3-4), the results again provide a near identical outcome to tests 7 to 10 in Table 3-4, that is: Ignitability Index: 0 Spread of Flame Index: 0 Heat Evolved Index: 0 Smoke Developed Index: 2 Based on these results and with reference to the tested facings and substrates, the tested indices are independent of the substrate to which the coated metallic facings are bonded. The results are indicative only of the fire performance of the coated metallic facings during the early stages of fire development, before involvement of the substrate. As such, the test results are independent of the thickness of the core material used (substrate) to which the coated metallic facings are bonded. Furthermore, the AS1530.3 results in tests 2, 3, 4 & 5 (Table 3-4) indicate that the DeltaOrb system and the DeltaTrim system achieves identical early fire hazard performance. Based on these results, the differing profiles of the DeltaOrb and DeltaTrim systems do not appear to have any significant effect on the achieved fire performance of the panels. As such, the DeltaOrb and DeltaTrim panels may be used interchangeably and the outcomes of this assessment remain applicable to both panel types.Revision 1-417'
