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 deemed to satisfy provisions.
Initially one specimen is tested in each of the machine and cross directions. Two additional specimens are then tested in the worst performing direction. A specimen of flooring system is subjected to a graded heat along its length with a radiant panel located at one end. An ignition flame is applied at the heated end. The distance that the specimen burns under the influence of the heat load is measured.
The heat flux at the point of extinction (CHF) is recorded together with the total amount of smoke generated during the test (Smoke Value).
All types of flooring can be tested, including:
- Carpets
- Carpet tiles
- Underlays
- Vinyl sheeting
- Floorboards
- Artificial Turf
In order to carry out this work we require three specimens in each direction (length and width), each 1050mm x 230mm in size, or alternately, enough sample for us to prepare them.
When submitting a sample for testing, please provide information detailing:
- Product name (as it should appear on the report)
- Composition (pile and backing for carpets)
- Thickness
- Mass or Density (pile mass for carpets)
- Installation process (loose lay or adhered)
- If underlay is to be used (specify underlay*)
We stock a limited range of commonly requested underlay products. Please consult a technologist to confirm availability. If the required product is not available, sufficient underlay must be provided to allow preparation of six specimens.
