Page 2 TITLE AWTA TEST CODE APPLICATION : Critical Radiant Flux Test : : T45C This test method is applicable to all flooring systems. It is used to provide data on the Critical Radiant Flux and Smoke evolution as required in the Building Code of Australia. A 1.05m x 0.24m specimen of the flooring system is subjected to 2 2 a graded heat flux of between 11 kW/m and 1.1 kW/m along it's length. The specimen is then ignited at the hot end and the distance that the specimen burns under the influence of the heat load is measured. The heat flux at the point of extinction is recorded together with the total amount of smoke generated in the test. A piece of the flooring system approximately 1.5m x 2m is required. This must include the underlay and any glue used in the system. The substrate must also be specified. From this sample, 3 specimens are prepared in the machine direction and three in the cross direction. One specimen is tested in each of the machine and cross directions. Two further specimens are then tested in the worse performing direction. The mean results in the worse direction are compared with the requirements of the relevant building code. The Building Code of Australia sets requirements for various classes of building in Specification C1.10a. 15 working days See current Fees List.
