b'Delta MW and EPS-FR Panel Awning and Patio Roof System The AS1530.1 test provides determination of combustibility for each material independently. The mineral wool has been tested to AS1530.1 (test 1 in Table 3-4) and is deemed not combustible.Low carbon steel is widely accepted as a non-combustible construction material. This is also confirmed by an AS1530.1 test for low carbon steel manufactured by Bluescope Australia (test 11 in Table 3-4) in which the test outcome demonstrates that the material (low carbon steel) is not deemed combustible. The NCC Guide further illudes to this in a number of cases by explicitly stating - non-combustible materials (such as steel). On this basis, low carbon steel is assumed to be non-combustible, regardless of who the manufacturer is or whether the manufacturer has tested the material to AS1530.1. This assessment is based on the assumption that EPS-FR is combustible and has the thermal characteristics outlined in Table 3-5. The values given in Table 3-5 were obtained through bench-scale testing that was undertaken by the University of Queensland (UQ) and is available in the UQ cladding material library as sample INS04.
