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.

(EXTENSION OF CARPETS DUE TO THE APPLICATION OF MECHANICAL FORCES - A MEASURE OF RUCKING AND/OR BUBBLING OF A CARPET IN USE) : : : T59A The method is applicable to all machine-made textile floor coverings. Specimens of carpet are subjected to cyclic loading and unloading and various mechanical properties determined after 10 load/recovery cycles. Samples shall be selected in accordance with AS2119. Specimens 30 x 5cm shall be cut from the sample in both length and width directions. There is considerable argument about interpretation of results obtained using this test method. The Woolmark Company in association with the Carpet Institute of Australia suggest this method (which has been withdrawn) only be used as a manufacturing tool to compare batch to batch non-recoverable extension. It is not appropriate for determining performance of carpet in use. As a guide, AWTA suggest that the sum of the non-recoverable extensions in length and width directions should not exceed 2.5 percent. : : : 7 days.
