ISO 9239 - For Critical Radiant Heat Flux of Flooring material

The AS ISO 9239 standard establishes the testing procedure for flooring materials. The test involves a floor panel laid horizontally. A radiant panel placed at an angle is then heated. The sample has a pilot flame applied to induce the panel to burn. The spread of fire is measured, and the critical radiant heat flux is determined. The test samples are to be 1050mm x 230mm. In total six samples should be tested.

 

The Building Code of Australia, through Clause C1.10 establishes the radiant heat flux requirements for materials in sprinklered or non-sprinklered applications. The critical radiant heat flux for sprinklered buildings is to be not less than 1.2kW/m² and for non-sprinklered buildings the critical radiant heat flux is to be not less than 2.2 kW/m²

 

 

The test samples are required to be conditioned. This can take up to a week with testing occurring after the conditioning is complete.
